4.2 FILLING THE FUEL TA NK

WARNING:

flammable. Keep fuel in a clean and tight
container. Keep fuel away from fire and heat.
Never put fuel in the fuel tank while the engine
is running or hot. Clean up any spilled fuel
before starting the engine.

Add fuel to the fuel tank as needed. See your engine
manual for the correct type and grade of fuel to be
used.

1. Put the unit in an open and well ventilated area
prior to refueling.

2. Stop the engine.

3. Allow the engine to cool.

4. Clean the fuel cap and in the area around the fuel
cap. Remove the cap from the fuel tank.

5. Fill the fuel tank with the proper grade of fuel
recommended by the engine manufacturer. Be
careful not to spill any fuel.

6. Install fuel cap on the fuel tank and tighten.

7. Clean up any spilled fuel before starting engine.

Use caution with fuel. Fuel is very

4.3 GENERAL LUBRICATION

Apply a small amount of oil to the pivot points as
required for smooth and proper operation.

Every 8 hours of operation, add Sten Mix Hi-Temp
Grease or equivalent to the lube fittings, in each of the
wheel hubs. After every 8 hours of operation, apply a
small amount of oil to the drive chain.

4.4 CHECKING FASTENERS

Each day before operating, check all nuts, bolts, and
other fasteners. Replace fasteners that are missing or
damaged.

4.5 CHECK TIRES

Keep tires properly inflated at all times. The correct air
pressure is 12 to 15 psi 83 to 103 kN/m

2

. After
checking and/or inflating, replace and tighten valve
caps to prevent air loss.

4.6 THE STEERING LEVERS

The steering levers are used to steer the unit. Pull up
on the left hand lever to turn to the left. Pull up on the
right lever to turn to the right. Holding both levers up
stops the unit. See Figures 5 and 6.

WARNING:

When the engine is running and
transmission is in gear, holding only one
steering lever up will cause the unit to circle
around one drive wheel.

4.7 THE STEERING LEVER LATCHES

The steering lever latches are used to hold the steering
levers in the up position. Engaging both steering lever
latches will free one of the operator’s hands for a
throttle adjustment, etc. (see Figures 2 and 3).
