Regular Maintenance
Engine Maintenance - General
Refer to the engine owner’s manual for all engine main-
tenance procedures and recommendations.
Clean Debris Out of Engine
Compartment
Service Interval: Every 25 Hours, or As Necessary
Stop the engine and allow the unit to cool. Remove all
debris from the engine compartment. Be sure all cooling
fins, radiators, screens, and areas around the exhaust
system are clean.
Clean Radiator
Service Interval: Every 25 Hours, or As Necessary
Clean the radiator, or radiator screen with compressed
air at regular intervals, or if dirty. The radiator is located
at the rear of the engine compartment on liquid-cooled
models. Liquid cooled models also have a removable
radiator screen (F, Figure 24). Clean all cooling system
components.
Clean Transmission Oil Cooler
Service Interval: Every 25 Hours, or As Necessary
The transmission oil cooler (C, Figures 24) is located
behind the engine and should be cleaned with com-
pressed air at regular intervals or if dirty.
Check Engine Coolant Level
Service Interval: Every 25 Hours, or As Necessary
The engine coolant level and quality should be checked
before each use, when the engine is off and cool.
1. Check the coolant level in the overflow reservoir (A,
Figure 24). Coolant should be between the “H” and
“L” marks on the tank.
2. If the coolant level is below the “L” mark on the over-
flow reservoir, add coolant by shutting off the engine,
allowing the engine to cool, removing the reservoir
cap, and adding coolant. Proper coolant mix is a
50/50 mixture of ethylene glycol and distilled water.
Change Engine Coolant
See Engine Manual for antifreeze recommendations and
change intervals. See Figures 24 for drain plug
locations.
WARNING
Keep the unit free of grass, leaves, and other
debris. Flammable debris many be ignited by hot
engine parts causing serious injury or property
damage.
