BLEEDING THE OIL SYSTEM
To facilitate bleeding of the oil system, we have added a hose connection
piece and a plastic hose to the set of tools. Take an empty oil can (1 liter)
and drill a 7 mm-diameter hole into the lid. Screw the hose connection
piece into the lid from the outside, and secure it from the inside with the
M8 hexagon nut.
Slip the plastic hose onto the hose connection piece, and you will have your
filling tool.
Fill 0.6 liters of engine oil into the can and remove the plug
1
next to the
steering head. Introduce the plastic hose into the vent hole
B
, and fill 0.6
liters of engine oil into the frame’s front tube. Remove plastic hose, start
engine, and let it idle (approx. 20 seconds) until oil escapes at the hole
B
.
As soon as oil starts to escape, turn off the engine, and mount the plug
together with the gasket.
Allow the engine to warm up, check the engine oil level and correct if neces-
sary. Afterwards, check the entire oil system for leakage.
Mount the engine guard.
Changing oil filter *
Replace the oil filter when changing the engine oil. Press the foot brake
pedal and place a screwdriver or similar between foot brake pedal and
stopper roll so that the oil filter cover is more accessible. Remove banjo bolt
2 and the three screws. Remove oil filter cover 3 and oil filter. Clean the
filter case, oil filter cover and sealing areas. Make sure the oil duct in the oil
filter cover is not clogged.
Place the new oil filter
4
on the connection in the oil filter cover and mount
together with a new seal
5
. Tighten the 3 screws in the filter cover to
5 Nm (4 ft.lb). Tighten the hollow screw with seals and tighten to 15 Nm
(11 ft.lb).
Finally, start the engine and check the oil system for leakage.
