Filling the Fuel Tank

1. Shut the engine off and set the parking brake.
2. Clean around each fuel tank cap and remove the
cap. Add fuel to both fuel tanks, until the level is
1/4 to 1/2 inch (6 to 13 mm) below the bottom of
the filler neck. This space in the tank allows the fuel
to expand. Do not fill the fuel tanks completely full.
3. Install fuel tank caps securely. Wipe up any fuel that
may have spilled.
4. If possible, fill the fuel tank after each use. This will
minimize possible buildup of condensation inside
the fuel tank.

Checking the Engine Oil Level

Before you start the engine and use the machine, check
the oil level in the engine crankcase; refer to Checking
Oil Level in , page

Switching the Fuel Tanks

Important: Do not run the machine out of fuel.
The fuel selector valve is located behind the left side
of the seat.
The unit has two fuel tanks. One tank is on the left
side and one on the right side. Each tank connects to
the fuel selector valve. From there a common fuel line
leads to the engine (Figure 6).
To use the left side fuel tank rotate the fuel selector
valve to the LH, lefthand location. To use the right
side fuel tank rotate the fuel selector valve to the RH,
righthand location (Figure 6)
Close the fuel selector valve before transporting or
storing machine.
