Operating Instructions
Also read the operating instructions of the equipment this
engine powers.
Pre-Start Checklist
• Check oil level. Add oil if low. Do not overfill.
• Check fuel level. Add fuel if low.
• Check cooling air intake areas and external
surfaces of engine. Make sure they are clean and
unobstructed.
• Check that the air cleaner components and all
shrouds, equipment covers, and guards are in
place and securely fastened.
• Check that any clutches or transmissions are
disengaged or placed in neutral. This is especially
important on equipment with hydrostatic drive.
The shift lever must be exactly in neutral to
prevent resistance which could keep the engine
from starting.
Carbon Monoxide can cause severe
nausea, fainting or death.
Avoid inhaling exhaust fumes, and
never run the engine in a closed
building or confined area.
Engine exhaust gases contain poisonous carbon monoxide.
Carbon monoxide is odorless, colorless, and can cause death
if inhaled. Avoid inhaling exhaust fumes, and never run the
engine in a closed building or confined area.
Cold Weather Starting Hints
1. Be sure to use the proper oil for the temperature
expected. Refer to Oil Recommendations.
2. Declutch all possible external loads.
3. Use fresh winter grade fuel. NOTE: Winter grade
gasoline has higher volatility to improve starting.
Do not use gasoline left over from summer.
4. Electric Start Models: Be sure the battery is in
good condition. A warm battery has much more
starting capacity than a cold battery.
