Cleaning the Engine Cooling

Areas

Clean the rotating screen, cooling fins, and external
surfaces of the engine every 100 operating hours
or more often under extremely dusty and dirty
conditions.
Important: Operating the engine with a
blocked rotating screen, dirty or plugged
cooling fins, or cooling shrouds removed will
cause engine damage due to overheating.
2. Level indicator hole
Important: Never clean the engine with
pressurized water because water could
contaminate the fuel system.

Brake Maintenance

Inspecting the Brakes

Brakes are a critical safety component of the
vehicle. As with all safety components, they should
be closely inspected at regular intervals to ensure
optimum performance and safety. The following
inspections should be done every 100 hours:
• Inspect the brake shoes for wear or damage.
If the lining (brake pad) thickness is less than
1/16 inch (1.6 mm), the brake shoes should
be replaced.
• Inspect the backing plate and other
components for signs of excessive wear or
deformation. If any deformation is found, the
appropriate components must be replaced.
• Check the brake fluid level; refer to Checking
the Brake Fluid Level.

Checking the Brake Fluid

Level

The brake fluid reservoir is filled and shipped from
the factory with DOT 3 brake fluid. Check the
level before the engine is first started and every 8
hours or daily, thereafter.
1. Park the machine on a level surface, set the
parking brake, turn the ignition off, and
remove the key.
2. Look at the side of the reservoir. The level
should be above the Minimum line (Figure 50).
If the fluid level is low, clean the area around
the cap, remove the cap, and fill the reservoir
to above the Minimum line. Do not overfill.
