I. CHECKING THE ENGINE OIL
LEVEL
1. Stand the machine on a level surface.
NOTE:
D Place the machine on a suitable stand.
D Make sure that the machine is upright.
2. Remove:
Dengine oil tank cap
3. Check:
Dengine oil level
The engine oil level should be between
the minimum level mark (a) and maxi-
mum level mark (b).
Below the minimum level mark >
Add the recommended engine oil to the
proper level.
a. If the oil level is between the minimum
and maximum level marks marked on the
oil level gauge, you may start the engine.
If there is no oil on the oil level gauge,
add oil up to the minimum level mark.
b. Start the engine and warm up until the oil
temperature rises to approximately
70mC(158mF).
c. Idle the engine more than 10 seconds
while keeping the machine upright. Then
stop the engine and check the oil level
on the upright machine.
W
Never attempt to remove the oil tank cap
just after high speed operation. The heat-
ed oil could spout out, causing danger.
Wait until the oil cools down to approxi-
mately 70m m C(158m m F).
- 17 -
c. Tighten the locknut (1).
W
A soft or spongy feeling in the brake
pedal can indicate the presence of air in
the brake system. Before the vehicle is
operated, the air must be removed by
bleeding the brake system. Air in the
brake system will considerably reduce
braking performance and could result in
loss of control and possibly an accident.
Therefore, check the brake system and
bleed if necessary.
CAUTION:
After adjusting the brake pedal position,
make sure that there is no brake drag.
NOTE:
D Before checking the engine oil level, wait
a few minutes until the oil has settled.
D Do not screw the dipstick in when
inspecting the oil level.
D Adjust the oil level to the maximum level
mark.
