Shock Absorbers; General Lubrication - Arctic Cat 550 H1 EFI Manual

When filling the cooling system, use a
coolant/water mixture which will satisfy
the coldest anticipated weather condi-
tions of the area in accordance with the
coolant manufacturer's recommenda-
tions. While the cooling system is being
filled, air pockets may develop; there-
fore, run the engine for five minutes
after the initial fill, shut the engine off,
and then fill the cooling system to the
bottom of the stand pipe in the radiator
neck.
„
NOTE: Use a good quality, biode-
gradable glycol-based, automotive-
type antifreeze.
! WARNING
Never check the coolant level when
the engine is hot or the cooling sys-
tem is under pressure.
CAUTION
After operating the ATV for the initial
5-10 minutes, stop the engine, allow
the engine to cool down, and check
the coolant level. Add coolant as
necessary.

SHOCK ABSORBERS

Each shock absorber should be visibly
checked weekly for excessive fluid leak-
age (some seal leakage may be observed
but it does not indicate the shock is in
need of replacement), cracks or breaks
in the lower case, or a bent shock rod. If
any one of these conditions is detected,
replacement is necessary.
„
NOTE: When the ATV is operated in
extremely cold weather (-23°C/-10°F or
colder), a small amount of leakage
may be present.
Unless the leakage is excessive, replace-
ment is not necessary. The shock
absorber has a spring force adjustment
sleeve with five adjustment positions to
allow the spring to be adjusted for dif-
ferent riding and loading conditions. If
the spring action is too soft or too stiff,
adjust it according to the chart.
„
NOTE: Use a spanner wrench to
adjust the sleeve to the desired
position.

GENERAL LUBRICATION

Cables
None of the cables require lubrication;
however, it is advisable to lubricate the
ends of the cables periodically with a
good cable lubricant.
Engine/Transmission Oil
and Filter
„ NOTE: Refer to the recommended
oil viscosity chart (on page 46) in
this manual for the proper engine
oil.
Change the engine oil and oil filter at
the scheduled intervals. The engine
should always be warm when the oil is
changed so the oil will drain easily and
completely.
1. Park the ATV on level ground.
2. Remove the oil level stick. Be care-
ful not to allow contaminates to
enter the opening.
