ENGINE MAINTENANCE
Follow the maintenance schedule and general mainte-
nance instructions in the engine maintenance and opera-
tion manual furnished with the power unit.
SPARK PLUG
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.
HYDRAULIC SYSTEM MAINTENANCE
• Check hydraulic fluid level daily. Add fluid per specifica
-
tions in this manual. (See "HYDRAULIC FLUID" under the
section titled "OPERATING INSTRUCTIONS".
• Remove condensed moisture from the hydraulic
fluid by pumping the hydraulic fluid 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 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 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.
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.
