SAFETY TEST Checklist Before each ride, carry out a safety check using the checklist. Take the safety check seriously. Carry out maintenance activities before you start your ride or ask a specialized Sachs dealer to do so. This will provide you with the cer tainty that your motorcycle corresponds to traffic regulations. A technically faultless motorcycle is a basic requirement for the safety of both yourself and other road users.
SAFETY TEST Load / lights WARNING For the sake of your safety, use only original Sachs accessories or products released by Sachs. Sachs cannot judge for each third-part product whether it can be safely used in combination with your Sachs motorcycle. Nor can a official approval give such a guarantee in all cases, since the test scope is not always sufficient. Ride safely Correctly loaded - Make sure that the left-right weight distribution is balanced. - Check that fastenings are correct and tight.
RIDING INSTRUCTIONS Ride economically and be aware of the environment Fuel consumption, environmental pollution and wear of engine, brakes and tyres depend on various factors. Your personal riding style is highly determinant for economical fuel consumption and exhaust gas and noise generation. While idling, the engine takes a long time to warm up to operational temperature. In the warm-up phase, however, the wear level and pollutant emissions are very high.
RIDING INSTRUCTIONS Running-in Running-in instructions for engine and transmission CAUTION Excessive revs while running-in the engine increases the wear of the engine. Engine faults during the running-in period must be immediately reported to a specialized Sachs dealer. NOTE During the running-in period, ride in frequently changing load and rpm ranges. Select winding and slightly hilly routes. Avoid constantly low rpm counts and full throttle under load. - During the first 500 km: Less than 1/2 throttle.
RIDING INSTRUCTIONS Starting with the electric starter 2 WARNING Propping up the scooter with the parking stand. Operate the rear handbrake lever to avoid a moving of the scooter. Avoid high engine rpm's while the vehicle is standing still, otherwise the clutch will engage. NOTE The scooter is equipped with a side stand switch. If the side stand is folded up the engine is shoot off and will not start. 5 3 1 Before starting - Propping up the scooter with the parking stand.
RIDING INSTRUCTIONS Starting with kick starter - Propping up the scooter when operating the kick starter. - Turn the ignition lock (1) with the key to its operating position . - Do not open the throttle (4). 6 - Depress the kick starter lever (6) quickly and the engine will start. - After the engine is running return the kick starter lever to its normal position. CAUTION The EMERGENCY OFF switch (3) is a safety device and should normally be in position . ON: Switch downwards.
RIDING INSTRUCTIONS Braking Wet brakes Washing the motorcycle or riding through water or rain can delay the braking effect due to wet or (in winter) ice-covered brake discs and linings. WARNING The brakes must first be operated until they are dry Salt film on the brakes When riding on salted streets without braking for a while, the full braking effect may be delayed.
RIDING INSTRUCTIONS Braking Stopping the engine 1 2 3 Braking The front brake and rear brake are operated independently from each other. The front brake is operated via the righthand brake lever (1) on the handlebars, and the rear brake is operated via the left-hand brake lever (2). When stopping or slowing down, release the throttle gas and operate both brakes at the same time.
SERVICE INSTRUCTIONS Servicing the motorbike / cleaning agents NOTE Regular, expert service will help maintain the value of your motorcycle and is a condition for guarantee claims for corrosion and other such damage. CAUTION Rubber and plastic parts will be damaged by caustic or penetrating cleaning agents or solvents.
SERVICE INSTRUCTIONS Servicing the motorbike / cleaning agents Operation in winter and anti-corrosion protection CAUTION Never use paint-polishing agents on plastic parts. - After a longish ride, thoroughly clean the chassis and the aluminium parts and preserve them with a commercially available anti-corrosion agent. PRESERVATION AGENTS When necessary, the motorcycle must be preserved with commercially available preserving and cleaning agents.
SERVICE INSTRUCTIONS Repairing paint damage Minor paint damage should be immediately repaired. 24 Servicing tyres Lay-up / commission If the motorcycle is not used for a longer period, it is recommended to support the motorcycle so that its weight is not on the tyres. You can prevent the tyres from becoming dry and brittle by spraying them with a silicone-rubber treatment. First thoroughly clean the tyres.
SERVICE INSTRUCTIONS Technical changes, accessories and spare parts WARNING CAUTION Technical changes to the motorcycle can lead to cancellation of the EC operating license. We recommend using only approved Sachs accessories and original Sachs spare parts for Sachs motorcycles. Should you want to make technical changes, observe our guidelines. This will serve to prevent the motorcycle from being damaged and the traffic and operational safety being retained.
