PVT SYSTEM

OVERHEATING / DIAGNOSIS
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 vehicle should be operated in Low when plowing or pulling heavy loads, or if extended
low speed operation is anticipated.

Low: Heavy pulling, basic operational speeds less than 7 MPH, riding
GENERAL RANGE OPERATION through rough terrain (swamps, mountains, ect.), or low ground speeds.
GUIDELINES:
High: High ground speeds, or speeds above 7 MPH.

Operating in Low Gear
Low gear should be used when pulling heavy loads, 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.
NOTE
Using High gear for heavy loads, hilly terrain, or in wet, muddy conditions will increase the chance of drive belt
burning.
