Do not use Cutting Oil for other purposes.●CuttingOilshouldbeusedonly fordrilling.Pleaserefer to Section 5-5 of thismanual for furtherwarningsandinstructionsaboutCuttingOil.

The Drill Motor will stop automatically when drilling operation is completed. If the Drill Motor fails to stop automatically, turn off the Motor Switch to stop it and then contact sales agent from which you have purchased your machine or an authorized dealer near you for repair.

CAUTIONDo not use power that is generated by an engine-driven welder.●Theuseofanengine-drivenwelderasapowersourcemaycauseyourmagneticdrivenmachineto

Don’t use this machine on the steel material being electrically welded.●Whentheelectricwelder isnotproperlygrounded,electricitywill run through theAtraAcemachinev ia i ts Magnet , causing possib le fa i lure ormalfunctioning,whichinturnmaycauseaccident.

Don’t force to feed cutter when drilling manually.●Because theHi-Broach and Jet-Broach haverather thincuttingedgeswith lesscuttingpressureresistanceascomparedtotwistdrill,donotforcetofeedthecutterwhendrillingmanually.

Ifyou feed itwith toomuch force, thecuttermaybreakorendupwithshorterlifethanotherwise.

Always use a compatible Pilot Pin.●ThePilotPinmustbecompatiblewiththecutter.AnimproperPilotPinmayresult inanaccident.SeeSection5-3 to identifycompatiblePilotPinsandcutters.TheproperPilotPin tobeusedwillvary,dependingonthetypeofcutter,thediameterofthecutter,andthelengthofthecutter.

Don’t switch to auto while drilling in manual mode.●Whenyouwantautomaticdrilling,set themachine

Don’t apply manual force when feeding in auto mode.●Don’tapplyforcetotheRodHandlewhenfeedinginautomode(with theRodHandlepushedtowardthemachine).

Don’t start drilling with manual feed.●Don’t startdrillingwithmanual feed. Onceyouhavestartedwithmanual feed,however,youmustnotchangemodetoautomaticfeedhalfwaythroughtheoperationbecausetheDrillMotormaycometoastopmakingitimpossibletocompletethehole.

Leaving the machine alone in a subzero C˚ environment for many hours may cause Drill Motor start-up failure at the initial startup. This is nothing unusual. Set the auto-feed switch to OFF (with the Rod Handle pulled out toward the operator) and run the machine idly for a few minutes. That should take care of initial startup failure.

6. MACHINE OPERATION

WARNING● Always Wear Safety Glasses.● Always Wear Hearing Protection.● Wear respiratory protective equipment.● Never touch the mounted cutter and the rotating

parts of the machine such as the Spindle Arbor after the power cable is connected to power source.

CAUTION● Do not use hard material such as a screwdriver,

to operate the Motor Switch. This may damage the panel and switch, which would lead to machine failure.

(9) Finishing Drilling Operation

WARNING● When drilling cycle is complete, the Drill Motor

will stop automatically. If it doesn’t, it’s a machine failure. Turn off the Motor Switch and contact sales agent through which you have purchase your machine or an authorized dealer near you for repair.

● Be alert at the end of drilling operation when slug will automatically pop out. Don’t touch slug: it’s very hot and has sharp edges.

6-4. Drilling Stacked Plates

CAUTION● Remove slug as each plated is f inished:

otherwise, being blocked by the slug left unremoved, the cutter cannot cut into the next layer of plate, which results in the Magnet base being pushed up possibly causing accident.

● For stacked plates drilling, always use manual feed and drill slowly and carefully.

● Before drilling stacked plates, securely clamp the plates together in place.

● When drilling stacked plates, retract the cutter as each layer of plate is finished in order to remove slug from the drilling area, then put another hole in the next layer of plate.

8. MAINTENANCE/SERVICE

WARNING ● Always disconnect the power and turn off the

switch before attempting any maintenance. Failure to disconnect the power and turn off the switch during set up, inspection or maintenance can cause accidents and severe injuries.

● Check to see periodically that mounting screws are tight. If you find them loose, retighten.
