MAN0646 (7/6/2007)
OWNER SERVICE
The information in this section is written for operators
who possess basic mechanical skills. If you need help,
your dealer has trained service technicians available.
For your protection, read and follow the safety informa-
tion in this manual.
Before performing any service or maintenance,
lower attachment to ground, turn off power unit
engine, remove key, and disconnect battery ground
cable (negative -).
■ Before working underneath, read manual
instructions, securely block up, and check stability.
Secure blocking prevents equipment from drop-
ping due to hydraulic leak down, hydraulic system
failure, or mechanical component failure.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
RADIATOR AND PRESCREEN
NOTICE
■ Clean the prescreen daily and the radiator fins
every 40 hours or annually, which ever is less. Do
not use high pressure on radiator fins to avoid radi-
ator damage.
ENGINE SERVICE
NOTE: Follow engine manufacturer recommendations
in engine manual.
Check Engine Oil Level
NOTE: Never attempt to check oil level while engine is
running. Serious injury or damage to equipment could
result.
1. Park power unit on a level surface.
2. Stop engine and clean off dirt and dust from around
dipstick.
3. Remove dipstick, check oil level. Oil level should
be between marks on dipstick. Avoid touching
exhaust manifold if unit has been running.
4. Add oil as necessary.
Change Engine Oil
NOTICE
■ Use care to prevent hot oil from contacting bare
skin.
1. Run engine to allow oil to become hot. This will
ensure that most foreign materials are in
suspension and will be flushed out with the oil.
2. Remove drain plug and drain crankcase.
3. Remove oil filter.
4. Install new oil filter.
5. Install drain plug and add oil.
NOTE: Refer to the engine manual for oil specifica-
tions, capacity, service rating, and proper grade.
Engine Coolant
Refer to the engine manual for the coolant specifica-
tions, coolant capacity, service rating, and proper mix-
ture.
LUBRICATION INFORMATION
1. Do not let excess grease collect on or around
parts, particularly when operating in sandy areas.
2. See Figure 6 for lubrication points and frequency or
lubrication based on normal operating conditions.
Severe or unusual conditions may require more
frequent lubrication.
3. Use a lithium grease of #2 consistency with a
MOLY (molybdenum disulfide) additive for all
locations unless otherwise noted. Be sure to clean
fittings thoroughly before attaching grease gun.
One good pump of most guns is sufficient when the
lubrication schedule is followed.
