Cleaning
Removing Debris from the
Machine
Service Interval:
After each use
Important:
Use care when using a high-pressure
washer, because it can damage decals, the engine,
and electrical and hydraulic systems, and it can
deplete grease. Ensure that the fuel-tank cap and
oil cap/dipstick are secure to avoid getting water
in the engine. Keep water away from electrical
items and hydraulic valves.
Important:
Operating the engine with blocked
screens, dirty or plugged cooling fins, and/or
cooling shrouds removed will result in engine
damage from overheating.
1.
Park the machine on a level surface, engage
the parking brake (if applicable), and lower the
boom.
2.
Shut off the engine, remove the key, and wait
for the engine to cool.
3.
Wipe away debris from the air cleaner.
4.
Clean any debris buildup on the engine and
muffler with a brush or blower.
Important:
It is preferable to blow dirt
out, rather than washing it out. If you use
water, keep it away from electrical items and
hydraulic valves. Do not use a high-pressure
washer on the engine.
5.
Clean debris from the oil cooler.
