Service and Repairs
Cooling System
To ensure proper engine cooling, make sure the grass
screen, cooling fins and other external surfaces of the
engine are kept clean at all times.
NOTE: Perform this maintenance procedure at the in-
terval specified in the Operator's Manual.
IMPORTANT: The engine that powers the Workman
HD vehicle is air- -cooled. Operating the engine with
dirty or plugged cooling fins, a blocked grass
screen or a plugged or dirty blower housing will re-
sult in engine overheating and engine damage.
1. Park vehicle on a level surface, stop engine, engage
parking brake and remove key from the ignition switch.
2. Raise or remove the bed or other attachment(s). If
bed is raised, place safety support on lift cylinder.
CAUTION
The engine may be hot. Allow engine to cool be-
fore cleaning the engine cooling fins.
IMPORTANT: Never clean engine with pressurized
water. Water could enter and contaminate the fuel
system.
3. Clean cooling fins on both cylinder heads.
4. Clean grass screen and blower housing of dirt and
debris (Fig. 1).
5. If necessary remove blower housing from engine for
more thorough engine cleaning.
IMPORTANT: Never operate engine without the
blower housing installed. Overheating and engine
damage will result.
6. Make sure blower housing and/or engine cylinder
shrouds are installed to the engine if removed.
