Fuel System
WARNING
 DO NOT operate the saw with a fuel leak.
 DO NOT fuel the saw with the engine
running.

DO NOT smoke or expose fuel to
open flames when filling the fuel
tank and/or working with fuel.
CAUTION
 Clean up spilled fuel prior to starting the
engine.

If over filled fuel may seep out from the
fuel cap vent when the saw is raised.
Adding Fuel
Check the fuel level daily and fill as necessary.
1. Lower the saw to the ground so it is level.
2. Stop the engine and let it cool down.
3. Remove the fuel tank cap.
Figure 26: Fuel Tank Cap
4. Fill the nine-gallon fuel tank with low sulfur or
ultra-low sulfur diesel fuel only. Refer to the
engine manual for a list of appropriate diesel
fuels.
5. Replace the fuel tank cap and tighten to secure.
Cold Weather Fuel
Diesel fuel can become thick in cold weather,
possibly resulting in a clogged fuel system and/or a
less efficient engine. Refer to the engine manual for
a list of appropriate diesel fuels in cold weather.
Storage
Fill the fuel tank to prevent condensation and
contamination in the tank for shorter storage
periods.
Drain the fuel tank and fuel lines for
extended storage periods.
Engine
WARNING
 DO NOT expose yourself or anyone else
to the direct line of the blade when
operating the saw.
 DO NOT leave the engine running
unattended.
 Operate the saw in well-
ventilated areas. Concentrated
engine exhaust can cause loss
of consciousness and/or death.
Engine Governor
The engine governor controls the engine speed.
DO NOT adjust the governor setting unless the
blade size requires a different maximum engine
speed. Occasionally measure the engine speed
and adjust to the required setting following the
steps below:
1. Use a handheld tachometer or other
appropriate device to measure the engine
speed at the engine crankshaft.
2. Adjust the engine governor screw to correct the
engine speed.
