Gas C ~ D In addition to sealing thv tank, the gas cap also serves to coniprnsate the pressure by venting the fuel tank, which is necessary to assure that fuel can flow unrestricted into the carburetor. It is therefore impotant that this pressure compensation is not hindered or blocked by inserting foam rubber rings or simi- lar seals. The gas cap is designed as a bayonet type closure. Therefore to open: Turn to the left

Fuel cock

The ilustration on this page shows the fuel cock and its three different posi- tions.

At "OPEN" - cock turned down - the tank will drain except for the reserve quantity.

At "SHUT" - cock turned foreward - the flow of fuel is stopped.

At "RESERVE" - cock turned upward - the tank will drain completely.

It is ~ ~ r ~ r a a a ~ j to close the fuel shut-off immediately after riding. Otherwise it could happen that row gasoline will cause damage of the crankshaft. A guarantee replacement could not be granted in these cases.

Operating Before the motor can be operated, it is necessary to add the specified transmission oil (see "Lubrication and Maitenance Schedule") and to remove the rubber string from the vent slot in the end cover.

Starting Engine

1. Move handlebar ignition switch lever to "ON" position. 2. Turn gasoline shut-off lever straight down, to open position. 3. Depress carburator "tickler" 3 to 5 seconds (for cold starts). 4. Mount moped and pump pedals as a bicycle to approximately 5 mph. 5. With left hand, pull starter control lever to handlebar. 6. With right hand, rotate twist grip counter-clockwise to open throttle and pull choke lever with

right thumb. 7. Release starter control lever and engine should start. 8. Continue to use cho'ke control until engine warms up. 9. If engine does not start, pull start lever and continue to pedal. Use choke and throttle as

required. Stop pedaling.

Moving Off Accelerate slowly after the motor has begun to run. The centrifugal clutch engages as the engine speed increases and the bike moves off. It is recommended to use the pedals for help when moving off on gradients.

Shutting Off Shut off motor with cutoff switch on handlebar. Do not shut off motor by applying the starter control. Shut fuel cock.

Anti-theft Lock

This device is built in the steering head. The key is inserted in the lock and the handle bars turned toward the right about 20 degrees. Now turn the key to the left and press in the lock until the lock catch engages in the slot in the front wheel fork. Finally turn the key toward the right and remove. Unloj in reverse sequence.

Warning: Remove 'key before oferating moped.

rools and Air Pump

Telescopic Front Fork The front wheel telescopic fork is practically maintenance free thanks to life time lubrication. Check tightness of all fork and handle bar mounting screws and nuts every 1200 miles12000 km for safety's sake. Should the springs become stiff after long periods of operation, have a specialist dismantle, clean and lubricate the fork. !4

Chain tension

The chain tension should be checked at certain operating intervals. This requires little effort and should therefore be accomplished before the chain begins to hit against the chain guard.

To check the chain tension lift the chain to the end of its play. The distance which the chain can be lifted - the slack - should amount to 0 98 - 1.38 in 124-35 mm with the vehicle loaded. See Fig. 20.

If this is not the case, loosen the axle nuts, "2" - Fig. 21 -, and change the position of the rear wheel correspondingly using the chain tightener. "I" - Fig. 21 -. Adjust the chain tightener u n ~ 30th sides in order to maintain the proper wheel alignment.

Fig. 20

Servicing Chains

The chains should be a) lubricated thoroughly with a good quality "chain hube" on the engaging side of the gears

every 300 milesi500 km and

b) removed and cleaned thoroughly in boiling water every 1800 miles/3000 km, then lubricated.

Cleaning Chains

a) Treat chains in kerosine or solvent to :emove dirt and hardened lubricants, by appling a steel brush and a normal brush to the links which are turned continuously until all of the links are clean and easy to move.

b) Place air dried chains in a warm special chain grease. Turn the chains several times after they have taken on the temperature of the grease bath. Move all of the links on the complete chain continuously and take the chain out of the bath as soon as the bath is just barely in a drip state. Hang up chains to drip dry.

Rear Wheel Drive The rear wheel drive is effected by pedalling and by motor force operating the rear wheel via one roller chains. These chains are held together by a chain lock. Make sure that the lock spring of the chain lock has its closed end facing toward the direction of travel.

2. ljnscrew speedometer cable nut on left side of hub and remove the cable.

3. Screw up brake cable (6) counternut on right side of wheel all the way, press down cable adjusting screw (1) as far as possible and disconnect holder (5). If necessary turn the bra- ke control lever clockwise with a wrench at hex nut (4).

4. Unscrew both axle nuts (3) and re- move strut of the fender from axle. Take off wheel downwards. When reinstalling, make sure that the fork holders on the right side engage in the slot of front wheel hub lever (2). Tighten axle nuts again. After con- necting the brake cable, the brakes will have to be adjusted again, i. e. the brake control lever travel at the handle bars must be about .40 in./ 10 mm so that the bra'kes catches. (See Fig. 25.)

Adjusting Brakes

It is necessary to adjust the brakes as soon as it is noticed that the brake control lever travel has increased. Normal travel is .40 in./ 10 mm, measured at the brake control lever near the con. necting nipple. When set at this distance the brake shoes shouid be felt as they grip.

Readjustment of the rear brakes

Screw the knurled nut (1, Fig. 27) onto the brake rod until the bra'ke lever on the engine (1, Fig. 28) extends down- ward horizontally when the brake is actuated.

Be extremely careful that the brake lever on the engine does not rub against the engine block when the brake is actuated.

Adjustment of brake light SV

The brake light switch must be ad- justed so that the brake light illumi- nates immediately when the coaster brake is actuated.

Adjustment is possible by moving the shackle (2, Fig. 28) on the brake rod.

Hubs

Maintenance to the hubs requires professional skill and should be accomplished by a trained mechanic. I Bearing adjustment

The hubs have an adjustable conical bearing. If readjustment is required care must be taken that the bearings are not adjusted too tight. The cone retaining nut must be screwed down tight while holding the cone in place. After securing recheck for freedom of movement. The wheel should have a slight amount of lateral play nfter it is mounted in the vehicle are tightened.

Lubrlcation

Relubrication is necessary after 5000. . .I0000 km 13000 mi.. . .6000 mi.

Excessive braking effect (grabbing)

xle nuts

By this rust de-

period

As all motorized vehicle brakes, the brakes are subject to so called "morning sickness". we mean that the brakes tend to grab even when applied lightly. This is caused by posits on the brake linings which forms when the brakes are not used for a longel (parking the vehicle over night) due to humidity or water which has seeped in. We recommend as a matter of principle that the brakes be actuated lightly, and then forcefully each time the vehicle is operated at the beginning. After 18.. .30 mi.130.. .50 km of driving the rust deposit will be ground off and the brakes will again operate perfectly. 1

Winter operation and corrosion protection If the vehicle is used dur~ng thc wlnter month, considerable damage to the frame and engine could result from salt on the streets. We recommend that the frame and engine be thorougly cleaned often during this season (parti- culary after longer periods of operating) with SACHS Engine and Hub Cleaner (F & S Order No. 0269 004 000) observing the following instructions. a) that the engine block, cylinder head, aluminum hub parts and other Darts on the vehicle be

cleaned with a brush (do not use a wire brush) and treated with coirosion protection paint (F & S Order No. 0269 001 100).

b) that the frame, chrome and enameled parts with SACHS Spray Preservative and Polish (F & S Order No. 0269 003 000).

Storing the engine H the engine is not used for a longer period of time, there is a danger that rust will form. Before storing the engine, shut off the engine by closing the fuel cock after the last run. Allow the carburetor to empty 11nt1l thr engine stops running, this will prevent the fuel line and carburetor system from gumming,up. To protect the bearings, crankshaft and inside of the cylinder, squirt 8 . . .10 cc's of SACHS corrosion protection oil (F & S Order No. 0969090005) into the carburetor inta'ke and 3 . . .5 cc's into the spark plug hole, and actuate the starting mechanism several times. For protecting the outside of the engine we recommend SACHS Spray Preservative and Polish (F & S Order No. 0269 003 000).
