PVT OVERHEATING/DIANOSIS
During routine maintenance or whenever PVT
system overheating is evident, it’s important to
check the inlet
and outlet ducting for obstructions.
Obstructions to air flow through the ducts will
significantly increase PVT system operating
temperatures. The RANGER should be operated
in D--1 when pulling or plowing heavy loads, or if
extended low speed operation is anticipated.

Possible Causes Solutions/What to do
Loading the Utility Task Vehicles
t
into a
truck or tall trailer when in high range.
Shift transmission to Low during loading of the Utility Task Ve-
hicles
t
to prevent belt burning
Starting out going up a steep incline from
a stopped position. When starting out on an incline, use Low, or dismount the Util-
ity Task Vehicles
t
after first applying the park brake and per-
form the “K” turn.
Driving at low RPM or low ground speed
(at approximately 3--7 MPH). Drive at higher speed or use Low. The use of Low is highly
recommended for cooler PVT operating temperatures and lon-
ger component life.
Insufficient warm--up of Utility Task Ve-
hicles
t
exposed to low ambient tempera-
tures.
Warm engine at least 5 min., then with transmission in neutral,
advance throttle to approx. 1/8 throttle in short bursts, 5 to 7
times. The belt will become more flexible and prevent belt
burning.
Slow and easy clutch engagement. Fast, effective use of the throttle for efficient engagement.
Towing/Pushing at low RPM/low ground
speed. Use Low only.
Plowing snow, dirt, etc./utility use. Use Low only.
Stuck in mud or snow. Shift the transmission to Low, carefully use fast, aggressive
throttle application to engage clutch.
W ARNI NG: Excessive
throttle may cause loss of control and vehicle overturn.
Climbing over large objects from a
stopped position. Shift the transmission to Low, carefully use fast, aggressive,
brief throttle application to engage clutch.
WARNING: Exces-
sive throttle may cause loss of control and vehicle overturn.
Belt slippage from water or snow ingestion
into the PVT system. Shift the transmission to neutral. Using the throttle, vary the
engine rpm from idle to
full throttle . Repeat several times as
required. During this procedure, the throttle should not be held
at the full position for more than 10 seconds. Clutch seals
should be inspected for damage if repeated leaking occurs.
Clutch malfunction. For inspection of clutch components, please contact your Po-
laris dealer. Shift transmission to Low during loading of the Util-
ity Task Vehicles
t
to prevent belt burning.
Poor engine performance. Fouled plugs, foreign material in gas tank, fuel lines, or carbu-
retor. Contact you dealer for further service information.
GENERAL RANGE OPERATION GUIDE-
LINES: Low: Heavy pulling, basic operational speeds less than 7
MPH, riding through rough terrain (swamps, mountains, ect.),
low ground speeds.
High: High ground speeds, speeds above 7 MPH.
Low Is Primary Drive Gear
Low is the primary driving gear for RANGER . Low should be used in ALL driving applications except for driving
on hard packed level surfaces with light loads. In this circumstance, High may be used. Using High for heavy
loads, hilly terrain, or in wet, muddy conditions will increase the chance of drive belt burning.
1.
Use Low as the primary
driving gear.
2.
Use High only on hard packed,
level surfaces with light loads.
