Yamaha pw80 - Manual (Page 16)

Your Yamaha engine has been designed to use
regular unleaded gasoline with a pump octane
number ([R + M]/2) of 86 or higher, or research
octane number of 91 or higher. If knocking or
pinging occurs, use a different brand of gaso­
line or premium unleaded fuel. Unleaded fuel
will give you longer spark plug life and reduced
maintenance cost.
ENGINE OIL (OIL TANK)
Make sure there is sufficient engine oil in the
oil tank. If necessary add oil.
Recommended oil:
Yamalube 2-S or air-cooled
2-stroke engine oil
Oil tank capacity:
0.95 L (0.84 Imp qt, 1.00 US qt)
TRANSMISSION OIL
The only servicing for you to do is to check and
fill the transmission lubricating oil. The trans­
mission dip stick is located right above the kick
starter. To check the level, warm the engine
up for several minutes, screw the dip stick com­
pletely out and then just rest the stick in the
hole.
NOTE: ------------------------------------------
When checking transmission oil level with the
dip stick, let the unscrewed dip stick just rest
on the case threads. Also, be sure the machine
is positioned straight up.

2. Maximum level
3. Minimum level
Recommended oil
Yamalube 4 (10W30)
or SAE 10W30 type SE motor oil
Oil capacity:
Total amount:
0.75 L (0.66 Imp qt, 0.79 US qt)
Periodic oil change:
0.65 L (0.57 Imp qt, 0.69 US qt)
The dip stick has a Minimum and Maximum
mark, and the oil level should be between the
two. If the level is lower, then and sufficient
oil to raise it to the proper level.
On the bottom of the engine there is a drain
plug. Remove it and drain all the transmission
oil out. Reinstall the drain plug (make sure it
is tight). Add oil through the dip stick hole.
1. Drain plug
Drain plug torque:
20 Nm (2.0m*kg, 14fHb)
NOTE: ______________________________
Do not add any chemical additives. Transmis­
sion oil also lubricates the clatch and additives
could cause the clutch to slip.
