Servicing the Air Cleaner
The air cleaner is a dry type with a “C” flow cartridge. A definite time schedule for changing the filter
cartridge cannot be determined because of varying operating conditions, therefore an air restriction
indicator lamp (Sect. 1-3; 16, Figure 1) is mounted on the control panel. Change the filter when the red
indicator lamp glows.
a. Cartridge Removal
(1)
Open right rear canopy door to gain access to the air cleaner.
(2)
Using a 5/16 socket, loosen the clamps which surround the air cleaner and secure it to the air
filter bracket.
(3)
Loosen and remove the clamp and air cleaner from the intake hose.
DO NOT attempt to clean or re-use old cartridge.
b. Cartridge Installation
(1)
Attach the new air filter cartridge to the intake hose and tighten the clamp.
(2)
Secure the air filter cartridge to the air filter bracket with the same two large clamps. DO NOT
over-tighten.
4.
Servicing the Fuel Filter
Refer to the Engine Manufacturers User’s Handbook for instructions on removal and replacement of
fuel filter elements.
5.
Drive Belt Service
Check all drive belts and adjust if necessary each 250 hours. Refer to Engine Manufacturers User’s
Manual for proper procedures.
6.
Engine Cooling System
NOTE:
Refer to the Engine Manufacturers User’s Manual for detailed instructions on servicing the engine’s
cooling system.
In all weather situations, the engine coolant should always contain a solution of 50% water and 50%
antifreeze (ethylene glycol). Rust inhibitors are recommended in the coolant as rust corrosion can still
occur.
Never remove the cap from a hot radiator. The radiator cap should not be
removed unless the engine temperature is 140º F (60º C) or below.
