MAINTENANCE
Engine Isolator Limiter Setting
Adjust the front engine isolator limiter so that the stop (D) is
bottomed out on the brace (E).
Hold the engine isolator limiter (D) and torque the jam nut (F)
to specification.
NOTE: Do not adjust this engine isolator limiter as a
torque stop or damage may occur. The approximate
distance from the face of the isolator to the face of
the engine strap is 0.107" (2.72mm).
CLEANING
Air Filter
The intake foam filter (A) limits snow ingestion into the intake
system. When operating in loose powder, check the top of the
foam filter periodically to remove any accumulation of snow.
NOTE: Do not operate a machine with the intake
filters removed. This may cause carburetor icing
resulting poor fuel economy or engine damage.
Water Sediment Trap
Most Polaris snowmobiles incorporate a patented carburetor
bowl water / sediment traps located at the bottom of each
carburetor. The trap consists of a hose with a plug which should
be inspected for contamination every 1000 miles (1600 km).
1. Turn the fuel tank supply valve to the “OFF” position.
2. Position a container or shop towels under the work area to
help catch some of the contaminated gasoline.
3. Slide the clamp (A) away from the drain plug (B) and
remove it from the sediment tube and drain the
contaminated material from the bowl. Repeat for each
carburetor.
4. Wipe off the residue from the plug and reinstall the clamps.
Nosepan Care
If your nosepan becomes dirty with soot, you can use Polaris
Carbon Clean (PN 2872890) to remove the soot.
STORAGE
Chassis And Hood
Proper storage starts by cleaning, washing and waxing the hood,
chassis, upholstery and plastic parts. Clean and touch up with
paint any rusted or bare metal surfaces. Ensure that all corrosive
salt and acids are removed from surfaces before beginning
preservation with waxes and rust inhibitors (grease, oil, or
paint).
If the machine is equipped with a battery, disconnect the battery
cables and clean the cables and battery posts. Fill battery to
proper level with distilled water and charge to full capacity.
Remove and store the battery in a cool dry place.
