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 prevent the fuel
from gumming. Run engine for a short period to circulate
the additive.
• Replace crankcase oil with new oil.
• Remove spark plugs and pour approximately 1 ounce (30
ml) of engine oil into each cylinder. Replace spark plugs
and crank the engine slowly to distribute the oil.
• Check hydraulic reservoir for water. If water is found,
change the oil and circulate it through the tool hose and
tool.
• Disconnect tool hoses.
ENGINE MAINTENANCE
Follow the maintenance schedule and general maintenance
instructions in the engine maintenance and operation
manual furnished with the power unit.
HYDRAULIC SYSTEM MAINTENANCE
• Check hydraulic uid level daily. Add uid per specica-
tions in this manual. (See "HYDRAULIC FLUID" under the
section titled "OPERATION".
• Remove condensed moisture from the hydraulic
uid by pumping the hydraulic uid into a 5 gal/20 l con-
tainer through the pressure hose. Make sure the engine is
at idle when performing this procedure. When the hydraulic
reservoir is empty turn the engine off immediately.
• Allow the uid to sit long enough for the water to settle to
the bottom of the container. Slowly pour the uid back into
the hydraulic tank, avoiding the water at the bottom of the
container.
• Each day, check hydraulic lines and ttings for leaks,
kinks, etc. Do not use your hand to perform this check.
• Change the hydraulic lter element every 200 hours of
operation. Change more often if cold, moist or dusty condi-
tions exist.
• Check oil cooler for debris. Remove debris with air pres-
sure.
SPARK PLUGS
On power units equipped with Briggs & Stratton Engines,
ONLY Champion RC12YC or equivalent can be used.
Incorrect type spark plugs can produce radio frequency
interference that will corrupt and damage the controller.
Failure to use the correct spark plug could result in a war-
ranty that will not be considered.
