Cooling System
IMPORTANT: The engine that powers the machine
is air−cooled. Operating the engine with dirty or
plugged cooling fins or a plugged or dirty blower
housing will result in engine overheating and dam-
age.
1. Park machine on a level surface. Make sure engine
is OFF. Remove spark plug wire from the spark plug.
IMPORTANT: Never clean engine with pressurized
water. Water could enter and contaminate the fuel
system.
2. Clean cooling fins on cylinder and cylinder head. Re-
move engine cylinder shroud from engine for more thor-
ough cleaning (Fig. 2).
3. Clean blower housing of dirt and debris (Fig. 3). Re-
move housing if necessary.
IMPORTANT: Never operate engine with the cylin-
der shroud and blower housing removed. Overheat-
ing and engine damage will result.
4. Make sure blower housing and/or engine cylinder
shroud are installed to the engine if removed.
5. Attach spark plug wire to spark plug.
