Pvt System Overheating / Diagnosis - Polaris GENERAL 2016 Service Manual

PVT SYSTEM OVERHEATING / DIAGNOSIS

During routine maintenance, or whenever PVT system
overheating is evident, it's important to check the inlet
and outlet duct for obstructions. Obstructions to air flow
through the ducts will significantly increase PVT system
operating temperatures. The vehicle should be operated
in Low when extended low vehicle speed operation is
anticipated.

Operating in Low Gear
Low gear should be used when riding through rough
terrain or when basic operational ground speeds are less
than 7 MPH. Use High gear when basic operational
ground speeds are more than 7 MPH.
General Sand / Dune Driving
The use of Low gear when continuously operating at
speeds less than 30 mph will greatly increase belt life in
sand/dune environments.
NOTICE
Do not shift from Low to High without coming to a
complete stop.
Using High gear for heavy loads, hilly terrain, sand/
dune environments, or in wet, muddy conditions will
increase the chance of drive belt burning.
