Periodic Maintenance Procedures
Change the engine oil every 250 hours of operation
after the initial change at 50 hours. Replace the
engine oil filter at the same time. See Replace
Engine Oil and Engine Oil Filter on page 5-20.
Check and Clean Radiator Fins
Dirt and dust adhering to the radiator fins reduce
the cooling performance, causing overheating.
Make it a rule to check the radiator fins daily and
clean as needed.
Note that a typical radiator is shown in Figure 5-10
for illustrative purposes only.
• Blow off dirt and dust from fins and radiator with
28 psi (0.19 MPa; 2 kgf/cm
2
) or less of
compressed air (Figure 5-10, (1)). Be careful
not to damage the fins with the compressed air.
• If there is a large amount of contamination on
the fins, apply detergent, thoroughly clean and
rinse with tap water.
CAUTION
• ALWAYS be environmentally
responsible.
• Follow the guidelines of the EPA or
other governmental agencies for the
proper disposal of hazardous
materials such as engine oil, diesel
fuel and engine coolant. Consult the
local authorities or reclamation facility.
• NEVER dispose of hazardous
materials irresponsibly by dumping
them into a sewer, on the ground, or
into ground water or waterways.
• Failure to follow these procedures may
seriously harm the environment.

A
CAUTION
FLYING OBJECT HAZARD!
• ALWAYS wear eye protection when
servicing the engine and when using
compressed air or high-pressure
water. Dust, flying debris, compressed
air, pressurized water or steam may
injure your eyes.
• Failure to comply may result in minor
or moderate injury.

CAUTION
NEVER use high-pressure water or
compressed air at greater than 28 psi
(193 kPa; 19 686 mmAq) or a wire brush
to clean the radiator fins. Radiator fins
damage easily.
