Introduction
Congratulations on your purchase of a JET “W” Series Premium Pallet Truck.
To better understand the proper use and safe operation of this pallet truck, please take a few
minutes to carefully read and follow the instructions contained in this manual. When finished
reading and understanding the manual, please file in a safe and convenient location for the life of
the pallet truck.
You will notice several important features about your JET Premium Pallet Truck. It features a 2-
7/8” lowered height, rounded fork tips and nylon entry/exit rollers to provide easy entry and exit of
pallets.
A large, easy-to-use ergonomic handle with a 200°turning radius allows maximum
maneuverability. The articulated steer wheel axle helps maintain floor contact on uneven
surfaces.
The cast iron pump design features top-of-the-stroke and overload by-pass systems, hardened
and chromed ram and piston, and a single point valve service for easy replacement. A special
lowering valve allows you to control the rate of descent and prevent “shock” loads.
Your JET Premium Pallet Truck is designed and built to give you years of trouble-free service
with minimum maintenance and service attention.

Troubleshooting
Possible problems could arise in the operation of your hydraulic pallet truck. Their probable
causes(s) and corrective action(s) follow:
Condition Probable Causes Corrective Action
Hydraulic unit does not lift Oil low in tank Make sure there is no oil leakage
from valve and add oil
Steel ball not seated in hydraulic
unit Place the lever in the down position and pump the handle
repeatedly
Worn U-packing in ram cylinder Consult authorized repair station
Once lifted truck lowers by itself Steel ball not seated in hydraulic
unit See “Cleaning Release Valve” on page 8
Worn U-packing in ram cylinder See “Cleaning Release Valve” on
page 8
Release valve not seated
properly See “Cleaning Release Valve” on page 8
Release valve not adjusted
properly Reload truck within load capacity and adjust valve by pressure
adjustment screw
Oil leakage from each valve Tighten plug of each valve
Fork does not lower Cam broken Replace cam chain
Up-down cam nut out of
adjustment Refer to “Adjusting Up-Down Cam” on page 8
Broken fork rods and linkage Replace broken parts
