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.
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. A warm battery has much more starting capacity
than a cold battery.
4. Use fresh winter grade fuel. NOTE: Winter grade
gasoline has higher volatility to improve starting.
Do not use gasoline left over from summer.
Starting
1. For a Cold Engine or a Warm Engine – Place
the throttle/choke control into the “fast/choke on”
position. This will also place the choke into the
“on” position. See Figure 5.
Figure 5. Throttle Position for Starting Engine.
2. Start the engine as follows:
For a Retractable Start Engine – 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.
Extend the starting rope periodically and check its
condition. If the rope is frayed, have it replaced
immediately by your Kohler Engine Service
Dealer.
