Operating Instructions
Also read the operating instructions of the equipment this engine powers.
Pre-Start Checklist
NOTE: This engine has been shipped without engine
oil. Fill with oil, otherwise it will not start.
• 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.
WARNING: Lethal Exhaust Gases!
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. See Figure 2 on page 4.
2. Declutch all possible external loads.
3. Set speed control at part throttle position.
4. A warm battery has much more starting capacity
than a cold battery.
5. Use fresh winter grade fuel. NOTE: Winter grade
gasoline has a higher volatility to improve starting.
Do not use gasoline left over from summer.
Starting
1. Turn fuel shut-off valve to ‘‘on’’ position. See
Figure 6.
Figure 5. Control Panel.
Figure 6. ‘‘On’’ Position of Fuel Shut-Off Valve.
2. For a Cold Engine – Place the throttle control
midway between the “slow” and “fast” positions.
See Figure 5. Place the choke control into the “on”
position.
For a Warm Engine (normal operating
temperatures) – Place the throttle control midway
between the “slow” and “fast” positions. The
choke is not required to start a warm engine.
3. Start the engine as follows:
For Retractable Start Engine – Turn engine
On/Off switch to ‘‘on’’ (see Figure 7) and SLOWLY
pull the starter handle until just past compression –
STOP! Return starter handle, pull firmly with a
smooth, steady motion to start. Pull the handle
straight out to avoid excessive rope wear from the
starter rope guide.
Figure 7. Retractable Start Engine On/Off Switch.
Extend the starting rope periodically and check its
condition. If the rope is frayed, have it replaced
immediately by your Kohler Engine Service Dealer.
