Lubrication

Checking the engine’s oil level.

Check the oil level in the engine when the Rider is on level ground. Do not check the oil with the engine running.

Open the engine cover.

Loosen the dipstick, pull it up and wipe it off.

Reinstall the dipstick and screw it all the way down

Pull the dipstick out again and read the oil level.

The oil level should be between the markings on the dipstick. If the level is approaching the ADD mark, top up the oil to the FULL mark on the dipstick.

ADD FULL

ADD FULL

The oil is topped off through the hole the dipstick sits in.

Fill the oil slowly. Tighten the dipstick correctly before starting the engine. Start and run the engine at idling speed for approx. 30 seconds. Turn off the motor. Wait 30 seconds and check the oil level. If necessary fill so that the oil comes up to the FULL mark on the dipstick.

Use synthetic engine oil class SJ-CF 5W/30 or 10W/30 for all temperature ranges. Mineral oil SAE30, class SF–CC can be used at temperatures > +5 °C (40 °F)

Do not mix different types of oil.

Replacing the engine oil

The engine oil should be changed the first time after 8 hours running time. It should then be changed after every 50 hours of running time.

When operating with a heavy load or at high ambient temperatures, replace every 25 hours.

WARNING! Engine oil can be very hot if it is

!drained directly after stopping the engine. Allow the engine to cool somewhat first.

1Place a container underneath the engine’s left oil drain plug.

2Remove the dipstick. Remove the drain plug from the engine’s left side.

3 Let the oil run out into the container.

4Fit the drain plug and tighten it.

5Fill with oil up to the ”FULL” mark on the dipstick The oil is topped off through the hole the dipstick sits in. See Checking the engine’s oil level for filling instructions.

The engine holds 1.5 litres (1.6 USqt) when the oil filter is not replaced and 1.7 litres (1.8 USqt) of oil when the oil filter is replaced.

6Run the engine warm, then check that there is no leakage from the oil plug.

IMPORTANT INFORMATION

Used engine oil, antifreeze etc. is a health hazard and must not be disposed of on the ground or in nature; it should always be disposed of at a workshop or appropriate disposal location.

Avoid skin contact; wash with soap and water in case of spills.

Lubricating the front wheel bearings

Jack up the front wheels and support the front end so the front wheels are off the ground.

1Remove the plastic cover that covers the centre of the wheel.

2Remove the circlip and washer on the front wheel axle.

3Lift off the wheel.

4Lubricate the stub axle with molybdenum disulphide grease*.

5Assemble the parts in the reverse order.

IMPORTANT INFORMATION

Check that the circlip enters the groove correctly.

*Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality. The most important property is that the grease provides good protection against corrosion.

General lubrication

All joints and bearings are lubricated using molybdenum disulphide grease during manufacture. Continue to lubricate using the same type of grease *. Lubricate the steering and control wires using engine oil.

Carry out this lubrication regularly.
