1 General safety instructions

Warning!Read and understand all instructions. Failureto follow all instructions listed below, mayresult in electric shock, fire and/or seriouspersonal injury.

Save these instructions!

Work Area

1. Keep your work area clean and welllit. Cluttered benches and dark areas in-vite accidents.

2. Do not operate power tools in explo-sive atmospheres, such as in thepresence of flammable liquids, gases,or dust. Power tools create sparkswhich may ignite the dust or fumes.

3. Keep bystanders, children, and visi-tors away while operating a powertool. Distractions can cause you to losecontrol.

Electrical Safety

4. Double Insulated tools are equippedwith a polarized plug (one blade iswider than the other.) This plug will fitin a polarized outlet only one way. Ifthe plug does not fit fully in the outlet,reverse the plug. If it still does not fit,contact a qualified electrician to installa polarized outlet. Do not change theplug in any way. Double Insulation

Class II Equipment eliminates theneed for the three wire grounded powercord and grounded power supply system.

5. Avoid body contact with groundedsurfaces such as pipes, radiators,ranges and refrigerators. There is anincreased risk of electric shock if yourbody is grounded.

6. Do not expose power tools to rain orwet conditions. Water entering a powertool will increase the risk of electricshock.

7. Do not abuse the cord. Never use thecord to carry the tools or pull the plugfrom an outlet. Keep cord away fromheat, oil, sharp edges or movingparts. Replace damaged cords imme-

7

diately. Damaged cords increase therisk of electric shock.

8. When operating a power tool outside,use an outdoor extension cordmarked "W-A" or "W." These cords arerated for outdoor use and reduce therisk of electric shock.

Personal Safety

9. Stay alert, watch what you are doingand use common sense when operat-ing a power tool. Do not use toolwhile tired or under the influence ofdrugs, alcohol, or medication. A mo-ment of inattention while operating pow-er tools may result in serious personalinjury.

10. Dress properly. Do not wear looseclothing or jewelry. Contain long hair.Keep your hair, clothing, and glovesaway from moving parts. Looseclothes, jewelry, or long hair can becaught in moving parts.

11. Avoid accidental starting. Be sureswitch is off before plugging in. Carry-ing tools with your finger on the switchor plugging in tools that have the switchon invites accidents.

12. Remove adjusting keys or wrenchesbefore turning the tool on. A wrench ora key that is left attached to a rotatingpart of the tool may result in personal in-jury.

13. Do not overreach. Keep proper foot-ing and balance at all times. Properfooting and balance enables better con-trol of the tool in unexpected situations.

14. Use safety equipment. Always weareye protection. Dust mask, non-skidsafety shoes, hard hat, or hearing pro-tection must be used for appropriateconditions.

Tool Use and Care

15. Use clamps or other practical way tosecure and support the work piece toa stable platform. Holding the work byhand or against your body is unstableand may lead to loss of control.

16. Do not force tool. Use the correct toolfor your application. The correct toolwill do the job better and safer at therate for which it is designed.

17. Do not use tool if switch does notturn it on or off. Any tool that cannot becontrolled with the switch is dangerousand must be repaired.

18. Disconnect the plug from the powersource before making any adjust-ments, changing accessories, or stor-ing the tool. Such preventive safetymeasures reduce the risk of starting thetool accidentally.

19. Store idle tools out of reach of chil-dren and other untrained persons.Tools are dangerous in the hands of un-trained users.

20. Maintain tools with care. Keep cuttingtools sharp and clean. Properly main-tained tools, with sharp cutting edgesare less likely to bind and are easier tocontrol.

21. Check for misalignment or binding ofmoving parts, breakage of parts, andany other condition that may affectthe tools operation. If damaged, havethe tool serviced before using. Manyaccidents are caused by poorly main-tained tools.

22. Use only accessories that are recom-mended by the manufacturer for yourmodel. Accessories that may be suit-able for one tool, may become haz-ardous when used on another tool.

SERVICE

23. Tool service must be performed onlyby qualified repair personnel. Serviceor maintenance performed by unquali-fied personnel could result in a risk of in-jury.

24. When servicing a tool, use only identi-cal replacement parts. Follow instruc-tions in the Maintenance section ofthis manual. Use of unauthorized partsor failure to follow Maintenance Instruc-tions may create a risk of electric shockor injury. Certain cleaning agents suchas gasoline, carbon tetrachloride, am-monia etc. may damage plastic parts.

2 Specific safety rules

DO NOT let comfort or familiarity with pro-duct (gained from repeated use) replacestrict adherence to router safety rules. If you

8

use this tool unsafely or incorrectly, you cansuffer serious personal injury.

1. Hold on the power tool by insulatedgripping surfaces when performing anoperations where the cutting tool maycontact hidden wiring or its own cord.Contact with a "live" wire will make ex-posed metal parts of the tool "live" andshock the operator.

2. Always disconnect tool from powersource before making adjustments orchanging bits.

3. Provide clearance under work piece forrouter bit when through cutting.

4. Check to see that the cord will not“hang up” during routing operation.Lead the cord away from the tool to-wards the rear.

5. Avoid cutting nails. Inspect for nailsand remove them from the work piecebefore operation.

6. Let the motor come to a completestop before removing the tool from workpiece and putting the tool down.

7. Do not leave the tool running. Operatethe tool only when hand-held.

8. Check the bit carefully for cracks ordamage before operation. Replacecracked or damaged bit immediately. Al-ways handle bits very carefully.

9. Never touch router bits immediately af-ter use. They may be extremely hot.Danger of injury!

10. Never tighten collet nut without a bit. Itcan be damaged.

11. Always keep hands away from rotatingparts to prevent personal injury.

12. Hold the tool firmly with both hands.13. Wear hearing protection during ex-

tended period of operation.14. Draw attention to the need to use cut-

ters of the correct shank diameter andsuitable for the speed of the tool.

15. Some material contains chemicalswhich may be toxic. Take caution toprevent dust inhalation and skin contact.Follow material supplier safety data.

16. Keep cutting pressure constant. Youcould overload the motor.

17. Make sure the bit is not contacting thework piece before the switch is turnedon.

18. Before using the tool on an actual workpiece, let it run for a while. Watch for

19. vibration or wobbling that could indicateimproperly installed bit.

SAVE THESE INSTRUCTIONS!

WARNING!

Some dust created by power sanding, saw-ing, grinding, drilling, and other constructionactivities contains chemicals known to theState of California to cause cancer, birthdefects or other reproductive harm. Someexamples of these chemicals are:• lead from lead-based paints,• crystalline silica from bricks and cement

and other masonry products, and arsenicand

• chromium from chemically-treated lumber.

Your risk from these exposures varies, de-pending on how often you do this type ofwork. To reduce your exposure to thesechemicals: work in a well ventilated area,and work with approved safety equipment,such as those dust masks that are speciallydesigned to filter out microscopic particles.

ting tapers, rabbet milling, profile milling,etc. The many, many possibilities often be-come apparent only after working with themill cutter. A variety of materials such aswood, synthetics, acryl, MDF, gypsumboard, etc. can be processed. We supplycorresponding and sensible accessories foryou to be able to do that right from the start:a parallel inset and a circular limit stop. Ahost of possible applications can be carriedout with these two tools. You will find addi-tional information about their usage in the in-structions at hand.The mill cutter, the rotating tool in your Prox-xon surface miller driven by a powerful uni-versal motor, achieves a speed of 27,500rpm and thus enables very precise and cleanwork. Collet chucks for mounting the millcutter are supplied in various sizes, allowingyou to use tools with differing shank diame-ters.Tool exchange is fast and comfortablethanks to the shaft lock provided with a stopbutton.The base plate of the MOF is made fromdie-cast aluminum for reasons of stabilityand precision. In order to ensure optimalantifrictional properties and the greatestpossible planarity, a synthetic plate is at-tached to the bottom. The device itself is guided by both columns.One of these takes on the additional func-tion of a depth-control stop. The millingdepth can be precisely adjusted with thethumbnut after making a zero setting (thisdepth-control stop also enables on-the-flysubmersion of the mill into the work piecewith the motor running).For quick pre-adjustment of the mill depthwithout special requirements on precision,the mill cutter router bit can be quickly andsimply moved within the guide columns afterreleasing the locking lever. The integratedsuction device (for connection to a vacuumcleaner) prevents dust nuisances and en-sures “clean” work results from this point ofview, also.

7 Operation

7.1 Mill selection:

WARNING!Make sure the mill cutter router bit is suitablefor at least 27,500 revolutions per minute.

Select a mill cutter router bit dependent onthe desired work results, i.e., the grooveform and the size that you want to fabricate.A variety of different shapes are available(e.g. groove cutters for rectangular groovesand V-grooves, channels mills for half-roundgrooves, and a variety of form cutters forevery conceivable groove and mill form).

CAUTON!When selecting, please keep in mind thatthe shank diameter of the mill cutter routerbit you want to use has to match the diame-ter of the supplied collet chucks.You can acquire a variety of high-grade pro-file mills for wood and similar materials fromProxxon.

11

These mill cutters (with a shank diameter of1/8” or 3.2 mm) are attuned to the use ofyour machine and guarantee excellent re-sults.

7.2 Insertion and replacement of themill cutter router bit (fig. 2):

WARNING!

Please make sure the plug has been pulledout when replacing the mill cutter! In all cases, ensure the mill cutter router bitused is suitable for the speed of the device. Let the router bit cool off after it has beenextensively used!Watch out when gripping: The mill cuttersare sharp-edged!

3. Insert another mill cutter.4. Lock shaft 6 using lock-on button 1,

screw on coupling nut 3 and tighten it us-ing the supplied wrench 2.

7.3 Milling depth adjustment:

WARNING!Please make sure the mains cable has beenpulled out when replacing the mill cutter!

Before milling, the desired milling depthmust be set. The MOF surface mill has twofeatures for this purpose: A milling depth-adjustment and a quick mill-depth adjust-ment. This is how they work:

7.3.1 Quick mill-depth adjustment(Fig. 4):

The quick mill-depth adjustment is used forpreadjusting: to quickly approach millingdepths without special requirements on pre-cision. One uses it to move the millingheight quickly into the proximity of the de-sired value.

12

1. Clamp in the desired cutter (see chapter7.2., „Insertion and replacement of themill cutter router bit“)

2. Pull out lock-on lever 1; the spring pre-load presses the foot into its lowest posi-tion.

3. Press milling-cutter head 2 into theguides against the spring force to a posi-tion corresponding to the desired millingheight or put the cutter with base plate 3on the edge of a slab (4) (or similar) andplace milling-cutter head 2 with pulledlock lever 1 into both columns to thedesired depth.

4. The height is fixed when locking lever 1 isfolded back.

7.3.2 Milling depth adjustment(Fig. 5):

The milling depth adjustment is used for final,precise adjustment of the milling height. Usingsetscrew 1, the desired height change can bemade exact by turning it back and forth.

1. Clamp in the desired cutter (see chapter7.2., „Insertion and replacement of themill cutter router bit“)

2. Pull out locking lever 3 and place the millcutter router bit with base plate 6 on astable support.

3. Carefully press the cutter against thespring force until the nip of the cutterlightly touches the surface of the sup-porting surface (see Fig. 5, left picture).

4. Now turn setscrew 1 toward the bottomuntil it „sits“ on limit-stop post 4 in themilling cutter.

5. The knurl and mill cutting position is now„zeroed“, so to say. Now just let go of themill cutter router bit and turn thesetscrew on its thread toward the top upto the desired depth (see 2nd picture,center). Please use scale 5 for orienta-tion: One entire rotation of the setscrewis equivalent to one millimeter height dif-ference.

6. Now push base plate 6 against the springforce so far in until the limit stop onsetscrew 1 „sits“ (see 3rd picture, right).The mill cutter router bit is now set deep-er than the bottom of base plate 6 by theamount of the value set in step 5. I.e.,this value is also the depth of the groovethat you can now mill out.

7. Fold locking lever 3 back. The milling height has now been adjusted.

7.4 Suction device (fig. 3)

Your surface miller comes equipped with asuction device. It is recommended to use itnot just because of the desired cleanlinessat the work area: when working with certain types of wood orother materials, harmful or explosive dustscan arise. In the interest of your own health,work only with the suction device connectedand always wear a dust protection mask inaddition. Make sure you use a vacuumcleaner that is suitable for the accruing dust.

1. Plug flexible suction hose 1 onto connec-tion 2

2. Connect flexible suction hose 1 usingrubber adapter 3 to the vacuum cleanerhose.

When working with the vacuum cleaner, it isrecommended you to use the PROXXONAS/E suction controller device.

7.5 Milling

7.5.1 General information on milling

• When working with the surface miller, useboth hands to guide the switched-on de-vice over the work piece. Always work inthe opposite direction of the cutter rota-tion (see figure 6). The rotating mill cutterrouter bit must always run with its cuttingedge against the milling movement.

• Otherwise, there is a risk that you willend up with poor milling work, cannotcleanly guide the device, or even that itleaps out of your hand.

• Pay attention that the milling depth is notset too deep! Always set the millingdepth to match the type of mill cutterrouter bit and the material to be milled.

• Too deep a mill setting and too great afeed rate lead to poor milling results andunnecessarily stresses the machine’s me-chanics! It is better to carry out severalmilling passes. Also, readjust the limitstop or the cutter height often.

• Always constrain or tightly clamp thework piece!

13

• For practical purposes, one should useone limit stop for each type of millingwork. There are different possibilities forthis, so only the most practical are ex-plained here:

7.5.2 Milling with limit stops

7.5.2.1 Milling with parallel limitstops

(Limit stop is included in the scope of deliv-ery, see fig. 7a, b)

As suggested by its name, you can use theparallel limit stop to fabricate grooves thatare parallel to the work piece edge, as illus-trated in fig. 7a. To do so, the supplied par-allel limit stop must be mounted and adjust-ed (see fig. 7b regarding this):

1. As in the illustration, push both guidebars (2) into bores 3 in limit stop 1 andfirmly tighten both headless screws (4)with the aid of a hollow hexagon wrench.

2. Press the limit stop with both guide barsin the form as shown in the illustration in-to both bores in base plate 5 and push itup to the desired distance (6).

3. Tightly clamp the limit stop with boththumbscrews (7)

You can now mill as shown in illustration 7a.Pay attention to the feed direction: Thecutter must always be able to work in theopposing direction! (See Fig. 6 and 7.5.1.:General information about milling). If this isnot the case, the limit stop must be moun-ted on the opposite side.

7.5.2.2 Milling with the circular limitstop.

(Circular stop is included in the scope of de-livery, see fig. 8a, b)

With the circular limit stop, you can mill outin circles or circle segments, as shown in il-lustration 8a. First, the limit stop needs to bemounted using the pin. To do so, proceed asdescribed in the previous point 7.1.1.„Milling with parallel limit stops“ aboutmounting the parallel limit stop, but ofcourse use the circular limit stop instead ofthe parallel one:

1. As in illustration 8a, push both guide bars(2) into bores 3 in limit stop 1 using thepin, and firmly tighten both headlessscrews (4) with the aid of a hollow hexa-gon wrench.

2. Press limit stop 1 with both guide bars (2)in the form as shown in the illustrationinto both bores in base plate 5 and pushit up to the desired distance (6). Pleasenote: The radius of the desired circle isthe distance of the pin to the mill cutterrouter bit axis!

3. Tightly clamp the limit stop with boththumbscrews (7)

4. Push the pin onto the previously markedposition of the circle or circle-segmentcenter

5. Switch on the mill and trace circles orarcs with the mill cutter.

CAUTION:When milling, keep the pin of the limit stoppressed down a bit (fig. 8a)!

7.5.3.1 Milling with longitudinal stops(fig. 9)

In cases where the traversing distance of theparallel limit stop is not sufficient for straightmilled grooves, you can make a longitudinalstop by yourself quickly and easily. Simplytightly clamp a straight strip, straight board,etc. using C-clamps to the position on thework piece as needed. Then the outer edgeof the device foot can trace the edge of thelimit stop and the milled groove can be man-ufactured. Please ensure enough clearancebetween the device foot-edge and the mill:of course, you must take this accordingly in-to consideration when positioning the limit-stop strip, the limit-stop board, etc.

7.5.3.2 Milling with simple masterforms (fig. 10)

To mill simple, irregular contours, it is rec-ommended to fabricate a template: The de-sired contours can be placed into a ca. 3/8” /10 mm thick board or similar and used as alimit stop.

14

To do this, clamp it to the work piece using,for example, C-clamps. In this way, the con-tours of the template can be „traced“ withthe MOF foot-edge and the desired milledgroove can be made.However, just as described in the previouspoint, in this procedure it is better to takethe clearance between the outer edge of theMOF device foot and the mill cutter routerbit into consideration, which should also bedone when cutting the template.

7.6 „On-the-fly“ submersion (fig. 11)

This refers to a method in which one doesnot press the milling cutter onto a workpiece edge in the work piece, but starts thegroove in the work piece surface freely. Caution: Please note, so-called on-the-flysubmersion is not to be used for all types ofmilling! Naturally, it must have correspondingcuts on the bottom side also.

1. Pre-select the milling depth. To do so,please start out as previously describedin the chapter „Milling depth adjustment“,but only up to and including point 6: thesetscrew should be at the desired posi-tion, but the locking lever (fig. 11, pos. 2)remains open.

2. Place the mill at the desired position onthe work piece and switch it on.

3. Slowly press the milling cutter down untilsetscrew 1 is seated on the column fordepth-control stop 3. The mill therebysubmerses into the work piece.

4. Mill out the desired groove. 5. If necessary, you can fix the milling height

with locking lever 2.

8 Service and maintenance

8.1 General

DANGER!Always turn switch OFF and always removeplug from power source before making anyadjustments, repairs, changing accessories,or storing the tool. Such preventive safety measures reduce therisk of starting the tool accidentally.

Do not use sol-vents or cleansing agents containing alcohol(e.g. benzene, cleaning alcohol, etc.) asthese can corrode the plastic housings.

The MOF surface mill is extensively mainte-nance free. However, to ensure a long serv-ice life you should clean the device aftereach use with a soft cloth, swab, or brush. Avacuum cleaner is also advisable for this.

External cleaning of the housing can be car-ried out using a soft, possibly moist cloth.While doing so, a mild detergent or othersuitable cleansing agent can be used. Donot use solvents or cleansing agents con-taining alcohol (e.g. benzene, cleaning alco-hol, etc.) as these can corrode the plastichousings.

8.2 Adjusting the clamping (Fig. 13):

If the clamping effect is not sufficient forworking, the clamping force of the stop leverof the height adjustment can be reset. Un-screw the grub screw 1 and turn the slottedscrew 2 slightly clockwise. Then check theclamping effect by activating the stop lever 3.Once the desired effect has been achieved,tighten the grub screw 1 again.
