MAINTENANCE
STORAGE
• Clean the unit thoroughly before storage. Do not use
water pressure.
• Always store the unit in a clean and dry facility.
• If the unit will be stored for a prolonged period (over
30 days), add a fuel additive to the fuel tank to pre-
vent the fuel from gumming. Run engine for a short
period to circulate the additive.
• Replace crankcase oil with new oil.
• Remove the spark plug and pour approximately 1
ounce (30 ml) of engine oil into the cylinder. Replace
the spark plug and crank the engine slowly to distrib-
ute the oil.
• Check hydraulic reservoir for water. If water is found,
change the oil and circulate it through the tool hose
and tool. (See HYDRAULIC SYSTEM MAINTE-
NANCE earlier in this section).
• Disconnect tool hoses.
ENGINE MAINTENANCE
Follow the maintenance schedule and general mainte-
nance instructions in the engine maintenance and op -
eration manual furnished with the power unit. Also see
maintenance schedule on pages 15 & 16.
HYDRAULIC SYSTEM
MAINTENANCE
• Check hydraulic fluid level daily. Add fluid per speci-
fications in this manual. (See HYDRAULIC FLUID
under the section titled OPERATION.
• Remove condensed moisture from the hydraulic
fluid by pumping the hydraulic fluid into a 5 gal/20
l container through the pressure hose. Make sure
the engine is at idle when performing this procedure.
When the hydraulic reservoir is empty turn the en-
gine off immediately.
• Allow the fluid to sit long enough for the water to
settle to the bottom of the container. Slowly pour the
fluid back into the hydraulic tank, avoiding the water
at the bottom of the container.
• Each day, check hydraulic lines and fittings for
leaks, kinks, etc. Do not use your hand to perform
this check.
• Change the hydraulic filter element every 100 hours
of operation or 6 months which ever comes first.
Change more often if cold, moist or dusty conditions
exist.
• Check oil cooler for debris. Remove debris with air
pressure.
