CHECK TIRE PRESSURES
Tire pressure should be checked periodically, and main-
tained at the levels shown in the chart. Note that these
pressures may differ slightly from the "Max Inflation"
stamped on the side-wall of the tires. The pressures
shown provide proper traction, improve cut quality, and
extend tire life.
CHECKING / ADDING FUEL
To add fuel:
1. Remove the fuel cap (see A, Figure 2).
2. Fill the tank to the bottom of the filler neck. This will
allow for fuel expansion.
NOTE: Do not overfill. Refer to your engine manual for
specific fuel recommendations.
3. Install and hand tighten the fuel cap.

FUEL FILTER

The fuel filter is located in the fuel line between fuel shut
off valve and carburetor, near the fuel pump. If filter is
dirty or clogged, replace as follows:
1. Disconnect the negative battery cable.
2. Place a container below the filter to catch spilled fuel.
3. Using a pliers, open and slide hose clamps from fuel
filter.
4. Remove hoses from filter.
5. Install new filter in proper flow direction in fuel line.
6. Secure with hose clamps.
7. Reconnect the negative battery cable when finished.

ENGINE MAINTENANCE

Refer to engine owners manual for all engine mainte-
nance procedures and recommendations.
CHECK HYDRAULIC OIL LEVEL
1. Before removing the reservoir cap, make sure the
area around the reservoir cap and fill neck of the
reservoir is free of dust, dirt, or other debris.
2. Unscrew the reservoir cap (B, Figure 11).
3. Look down the filler neck of the hydraulic oil reservoir
(A, Figure 11) and observe the oil level. When cold,
the oil level should approximately 2-1/2" (6,4 cm)
below top of the filler neck.
4. If necessary, add either Mobil 1™, 15W-50 synthetic
oil or Castrol Syntec™ 5W-50 oil. DO NOT use con-
ventional oils.
5. Reinstall the reservoir cap.

WARNING
Gasoline is highly flammable and must be
handled with care. Never fill the tank when the
engine is still hot from recent operation. Do not
allow open flame, smoking or matches in the area.
Avoid over-filling and wipe up any spills.
Do not remove fuel filter when engine is hot, as
spilled gasoline may ignite. DO NOT spread hose
clamps further than necessary. Ensure clamps
grip hoses firmly over filter after installation.
Do not use gasoline containing METHANOL,
gasohol containing more than 10% ethanol,
gasoline additives, premium gasoline, or white
gas because engine/fuel system damage
could result.
