Note: This situation may be particularly prevalent if the
rear discharge cutting unit is being used. The front of the
radiator can be cleaned thoroughly by blowing with
compressed air from the fan side of the radiator. Make sure
to clean out any debris that settles to the bottom of the
screen. The screen in front of radiator can be removed—by
loosening wing nuts at top of screen—to make cleaning
easier.
Changing Engine Oil And Filter
Check oil level after each day’s operation or each time
machine is used. Change oil after every 50 hours of
operation; change oil filter after first 50 hours and every
100 hours operation thereafter. If possible, run engine just
before changing oil because warm oil flows better and
carries more contaminants than cold oil.
1. Position machine on a level surface.
2. Open the hood. Set drain pan under the oil pan and in
line with drain plug (Fig. 36).

oil that is spilled.
7. Fill crankcase with oil; refer to Check Crankcase Oil.
Servicing Fuel System
Note: Refer to Fill Fuel Tank With Diesel Fuel for proper
fuel recommendations.
Danger
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
• Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 1 in. (25 mm)
below the bottom of the filler neck. This empty
space in the tank allows the fuel to expand.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
• Store fuel in a clean, safety-approved container
and keep the cap in place.
Fuel Tank
Drain and clean fuel tank every 800 hours operation or
yearly, whichever comes first. Also, drain and clean tank if
fuel system becomes contaminated or if machine is to be
stored for an extended period. Use clean diesel fuel to flush
out the tank.
Fuel Lines and Connections
Check lines and connections every 400 hours or yearly,
whichever comes first. Inspect for deterioration, damage or
loose connections.
Water Separator
Drain water or other contaminants from water separator
(Fig. 38) daily.
1. Place a clean container under water separator. Water
separator is mounted to inside of frame, next to left side
of engine.
2. Loosen drain plug on bottom of filter canister. Tighten
plug after draining.
