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

Possible Causes
Loading the Utility Task Vehiclest into a
truck or tall trailer when in high range.
Starting out going up a steep incline from
a stopped position.
Driving at low RPM or low ground speed
(at approximately 3--7 MPH).
Insufficient warm--up of Utility Task Ve-
hiclest exposed to low ambient tempera-
tures.
Slow and easy clutch engagement.
Towing/Pushing at low RPM/low ground
speed.
Plowing snow, dirt, etc./utility use.
Stuck in mud or snow.
Climbing over large objects from a
stopped position.
Belt slippage from water or snow ingestion
into the PVT system.
Clutch malfunction.
Poor engine performance.
GENERAL RANGE OPERATION GUIDE-
LINES:
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.
Use Low as the primary
1.
driving gear.
Use High only on hard packed,

level surfaces with light loads.

temperatures. The RANGER should be operated
in D--1 when pulling or plowing heavy loads, or if
extended low speed operation is anticipated.
Solutions/What to do
Shift transmission to Low during loading of the Utility Task Ve-
hiclest to prevent belt burning
When starting out on an incline, use Low, or dismount the Util-
ity Task Vehiclest after first applying the park brake and per-
form the "K" turn.
Drive at higher speed or use Low. The use of Low is highly
recommended for cooler PVT operating temperatures and lon-
ger component life.
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.
Fast, effective use of the throttle for efficient engagement.
Use Low only.
Use Low only.
Shift the transmission to Low, carefully use fast, aggressive
throttle application to engage clutch.
throttle may cause loss of control and vehicle overturn.
Shift the transmission to Low, carefully use fast, aggressive,
brief throttle application to engage clutch.
sive throttle may cause loss of control and vehicle overturn.
Shift the transmission to neutral. Using the throttle, vary the
engine rpm from idle to full
required. During this procedure, the throttle should not be held
at the full position for more than 10 seconds.
should be inspected for damage if repeated leaking occurs.
For inspection of clutch components, please contact your Po-
laris dealer. Shift transmission to Low during loading of the Util-
ity Task Vehiclest to prevent belt burning.
Fouled plugs, foreign material in gas tank, fuel lines, or carbu-
retor. Contact you dealer for further service information.
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.
