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
3100 is air–cooled. Operating the engine with dirty
or plugged cooling fins, a blocked grass screen, or
a plugged or dirty blower housing will result in en-
gine 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 (see
Operator’s Manual).
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). Remove screen and housing if neces-
sary.
IMPORTANT: Never operate engine without the
blower housing installed. Overheating and engine
damage will result.
5. Make sure grass screen and blower housing are re-
installed to the engine if removed.
