NOTICE
Your mower's engine is shipped from the factory without
engine oil. A bottle of engine oil (15 fluid oz.) is included
with your mower's packaging. Check oil level before starting
engine. If you start the engine without oil, the engine will be
damaged beyond repair and will void your warranty.
Checking and Adding Engine Oil
Types of Oil to Use
Use high detergent motor oil having an API service classifi-
cation of SG, SH, SJ or higher. Choose motor oil viscosity
according to Fig. 15. For most range of service tempera-
tures, 10-30 viscosity oil is recommended.
NOTICE
Use of non-detergent oil or 2-stroke engine oil may damage
the engine and void your warranty.
1. Check oil level each time before starting engine.
Check oil level daily or every eight (8) hours of
operation. Keep oil level at UPPER LEVEL on dipstick
(See Figure 9).
2. Always check oil level with engine cool and mower on
flat, level surface.
3. Clean around oil fill spout, remove dipstick and wipe
clean with a cloth.
4. Replace dipstick – without tightening. Make sure
dipstick is fully inserted into oil fill spout. Remove and
check oil level.
5. Oil level should be at UPPER LEVEL on dipstick. See
Figure 9.
6. If oil is needed, add oil slowly through the oil fill
spout and recheck. Do not overfill.
NOTICE
Overfilling with oil may cause hard starting, spark plug fouling,
and engine smoking.
