  • Page 26 DRIVING AND OPERATION OF CONTROLS Removing scooter Take hold of handlebars and push machine forward. At the same from stand time place your left foot in front of stand to avoid movement, and roll machine off stand. When the engine has been started (neutral gear), pull the clutch lever and turn the gear control twist–grip to position 1.
  • Page 27 Locking of the wheels should be avoided. Use both brakes together if possible. Your TOURIST four–stroke engine, in contrast to a two–stroke engine, will take over a large part of the braking on long descents.
  • Page 28 The machine is held on the left side by the handlebars and the Putting on stand stand pressed to the ground with the foot. Whilst holding the scooter by the handlebars, pull it smartly backwards until the catch of the stand is reached. This is done without difficulty and without having to lift the scooter.
  • Page 29 SCOOTER MAINTENANCE AND CARE Cleaning The reliability of operation and the service life of the machine depend to a great extent on maintenance and cleaning. Very often, trouble and annoyance can be traced back to lack of proper care. The highly–polished coachwork is best washed with a sponge under running water and afterwards dried with a chamois leather, as is done with any car.
  • Page 30 When replacing the rear body cowling, take care to connect the stop light cable to the correct connectors. When fastening the frame–retaining bolts, make quite sure that the cables for the braking Note! and tail lights are not trapped under the frame (danger of short–circuiting).
  • Page 31 Engine Maintenance Lubrication is of particular importance with a four–stroke engine and the instructions for oil– changing must therefore be strictly adhered to. Use only proprietary oils such as Mobiloil Special for the whole year round or Mobiloil AF in the summer (SAE 40), and Mobiloil A in the winter (SAE 30).
  • Page 32 open the oil filter plug (1) at the top of the cylinder cover and extract the drain plug at the bottom of the engine housing (Figs.3 and 4). When the old oil has drained away, replace the drain plug and fill with just over 1 3/4 pints of proprietary oil such as Mobiloil Special. Turn over the engine for a short time in neutral and then drain the engine oil again.
  • Page 33 Checking the engine oil level Pull out and wipe dipstick (Fig. 4), then re–insert it as far as the screw cap. Check the oil level every time you fill up with petrol; it must never fall below the bottom mark on the dipstick. The maximum level is to the top mark on the dipstick.

  • Page 39 If, with a cold engine, the throttle is operated several times,the pump injects into the mixing chamber amply sufficient petrol for starting. The cylinder of the accelerator pump is the lower enlarged extremity of the pump needle jet, into which the pump piston with valve disc and the pump valve screw are inserted. The pump spring presses the piston against the bottom end of the jet needle.
  • Page 40 The inflow of fuel during fast running is determined by the main jet (16); with the engine running not so fast (about 3500 r.p.m.), the inflow of fuel is determined by the pump–needle jet (10) and jet needle (8). The idling jet (17) fixed on the carburettor housing by the idling jet return screw (18) provides for correct quantity of fuel necessary for idling.
  • Page 41 Micronic air filter The micronic air filter needs no servicing. It keeps any dust out of the engine. The life of the paper filter insert therefore depends on the amount of dirt handled. In town and on tarred roads, it should last some 5000 miles.
  • Page 42 Clutch Power is transmitted to the gearbox by means of a multi–plate clutch. Special care must be taken that the clutch lever on the handlebar has 1/16”–1/8” play. If there is too much play, the clutch does not disengage freely; too little play causes the clutch to slip and results in rapid wear. The adjuster screw for the clutch control cable is placed on the left hand engine housing cover.
  • Page 43 Gear change control The gear is changed by twist–grip control on the handlebars. Gear change from handlebar to gear shift lever is by two Bowden cables. Locking of the gears in the twist–grip can be suited to the touch of the driver by adjustment of the screw (between the figures). For readjustment of the gear–shift, adjuster screws are provided on the clutch cover (see Fig.9).
  • Page 44 The Brakes The front brake is adjusted by the Bowden cable adjuster screw on, the hub brake disc at the right–hand side. If the adjustment of the screw has reached its limits, the adjuster screw is screwed in completely, and the brake actuating lever is advanced by removing nut 3, prising actuating lever from the cam spindle and replacing one notch clockwise.

    It is advisable to pay special attention to the ignition and lighting system, as the reliability of the engine depends on it. Dismantling and reassembling should be done only at a HEINKEL or BOSCH Service workshop, so as to avoid damage to crankshaft or dynamo. From time to time, have the equipment checked by a specialist.
  • Page 47 This includes: a) Checking the contact breaker points the gap should be .014–.018 ins. (every 1500 to 2000 miles); b) Greasing of the lubrication felt at the contact breaker (use grease, not oil). c) Removal of carbon deposits and checking of brushes. require no further maintenance, but it is advisable to check the cable Coil and Regulator connections from time to time (to gain access to these, raise the cowling).
  • Page 48 Plug Check the electrode gap every 1200–2000 miles. It should be .020–.024 ins. The sparking plug is accessible from the lug gage boot. Push the little metal flop aside and remove the plug, using the box spanner. When screwing in the spark plug, do so by hand, using the spanner only for final tightening, so as not to damage the thread.
  • Page 49 up with distilled water. The acid level should be kept a little above the top edge of the plates. Only accumulator acid (1.28) should be used. For charging instructions, see battery cover. Do not let petrol or parrafin touch the battery. Should the scooter be laid up for some time (4 weeks or more), the batteries should be taken out and taken care of separately.

    Fuse Box The fuse box is located at the top right–hand side of the front shield. Access to the fuses is gained by unscrewing the fuse box cover (Fig. 14). Wheel changing Front wheel Disconnect Bowden control cable at brake lever and lean the machine over on its right side until the footplate rests on the ground and loosen 4 cap nuts with the box spanner.
  • Page 51 that the speedometer cable and gearbox are correctly located. The speedometer mechanism has 2 pins which ensure correct fitting of the drive to the counter ring. The notch in the brake anchor or, at the first sharp braking, the plate must be located correctly in the right–hand front fork, wheel will jam and the driver will fall.
  • Page 52 Checking the tyre Pressure The life of your tyres depends to a great extent on correct pressure and careful treatment. Inflate tyres as specified on Page 19. Changing the Tyres Since, in our experience, more strain is put on the rear tyre than on the front tyre, it is advisable, in the interests of even tyre wear, to change over the front and rear wheels every 1850–2500 miles.
  • Page 53 Removing the tyres Make it a principle never to use force when removing or fitting tyres! Unscrew the valve caps and screw out valve insert with reversed cap, let the air out and unscrew rim nuts from the valve. Lay the wheel flat on the ground and, by treading on it, loosen the tyre bead all round.
  • Page 54 the rim. Then take out the inner tube, stand the wheel up and, using the tyre levers, force the second tyre bead (see Fig. 17) over the edge of the rim and pull the tyre sideways and off the rim. Fitting the tyres Place the slightly pumped–up inner tube in the cover so that there are no creases and with the inner tube valve, inserted at the side, facing upwards.

    edge of the rim with the tyre lever (see Fig. 18), until, in the vicinity of the valve, the last piece jumps into place; tighten the rim nuts. Always see (Fig.19) that (B) both beads lie in the drop–base rim whilst at (A) the opposite side of the tyre is being fitted. Pump the tyre up a little and check that both beads are securely inside the rim, as prescribed, by lifting up the wheel and letting it bounce on the ground.

    Every 5000 miles, the oil in the arms of the front fork must be drained and approx 30 cc. of new oil, such as Mobiloil A (SAE 30), poured into each arm (see Fig. 21). To remove the fork, take off the front mudguard. These jobs should only be done at a HEINKEL Service Workshop, which also ensures correct assembly.

    must be greased every 1500 miles with ball–bearing grease, such as Mobilgrease NO.5 (see Fig. 22). Exhaust Once the retaining ring nut has been loosened, the air duct can be turned approximately 90° so that the exhaust can be removed (see Fig. 23). Exhaust 1.
  • Page 59: Winter Operation

    WINTER OPERATION If the scooter is used in winter too, take care to drive slowly and to use brakes carefully on slippery roads. If all–year–round oil, such as Mobiloil Special, is not used, fill up with winter oil (SAE 30) – at any rate when the temperature drops below 40° F. To economise on weight, the scooter batteries are correspondingly small.
  • Page 60 STORING OF SCOOTER If the vehicle is not going to be used for a fairly prolonged period (wintering, or for any other reason), you should: 1. Clean the whole scooter thoroughly. 2. Change the oil with anti–corrosion oil, such as Mobil–Kote 503, just before storing the machine (approx.
  • Page 61: Storage

    TAKING THE VEHICLE OUT OF STORAGE Run the engine warm; drain off anti–corrosion oil and fill up with 1.5 litres of proprietary oil, such as Mobiloil Special. Carry out the next oil–changes as prescribed in the Lubricating Schedule.
