Introduction
Congratulations on your purchase of a JET Electric High Lift Pallet Truck.
This electric high lift pallet truck is designed to reduce lifting injuries and increase productivity by lifting,
lowering, and transporting open pallets and skids only with ease. It does not work with closed pallets
unless the pallet is placed on top of forks. An optional steel platform converts the electric high lift pallet
truck to a mobile workstation.
Notable features include a Fenner/Haldex Barnes mini-hydraulic pump system with built-in automatic
overload protection. Power is provided by AC Delco maintenance-free 12V battery with 585 cold
cranking amps. The heavy-duty welded steel frame features a powder coat finish to inhibit rust. With
regular maintenance, your electric high lift pallet truck will provide years of dependable service.
The specifications in this manual are given as general information and are not binding. WMH Tool Group
reserves the right to effect, at any time and without prior notice, changes or alterations to parts,
fittings, and accessory equipment deemed necessary for any reason whatsoever.

Assembly & Adjustment
(refer to exploded views)
1. Remove packing material carefully and
inspect for any damage during shipment.
2. Insert handle (102) into the socket of
cylinder (160); lock it with pin (108) and two
screws (109). Swing the handle up and
down to see if it moves freely. Attach
tension spring (105).
3. Open electrical control case by removing
thumb screws (256) and cover (255). Insert
up/down switch wire and plug (184) hanging
down from handle (102) into socket (221) in
the case. Insert two 5 Amp fuses (277) into
two sockets F1/F2.
4. Check the electrical device and elements in
the case to make sure none are loose or
damaged. Tighten any elements if loose.
5. Check high pressure oil pipe (282) in the
hydraulic system to confirm it is not loose.
Tighten if loose. Open cover (217) to check
hydraulic level.
6. Push “Up” button (197) on top of handle
(102) intermittently to lift the fork. Push and
hold the “Up” button to lift the forks to their
highest position. Then push and hold the
“Down” button (197) to lower the forks to
their lowest position. Repeat this procedure
3 to 4 times with full up and down travel to
release any possible air in the hydraulic
system and to confirm all components are
functioning correctly.
7. Close cover (255).
Safety Precautions
1. Read and understand owner's manual
before operation.
2. Do not exceed rated capacity.
3. Before using pallet truck, lift and lower the
forks several times with no load to release
any air that may be trapped in the hydraulic
system.
4. Never allow anyone to ride on the pallet
truck.
5. Operate on smooth, level finished floors
only. Automatic brake system will not
engage properly if forks are raised on
uneven floor. Do not use on slope.
6. Always keep hands and feet clear from all
moving parts including forks, legs, piston
rod (406) and mid-cylinder (413).
7. Always secure load equally on the forks
nearest the bulkhead before lifting or
lowering. Do not lift load with fork tip only.
8. Automatic overload safety valve will open if
pallet truck is overloaded. If overloaded, do
not push the "Up" button as this will reduce
the life of the pump station.
9. When transporting loads, always keep
people clear from pallet truck and transport
in the lowered position only.
 WARNING
Failure to comply with all of these safety
precautions may result in loss of load,
damage to pallet truck, personal injury
and/or property damage.
Operation
The pallet truck is designed for use with open
style pallets or skids only. Closed style pallets
must be placed on top of forks prior to use.
The handle is designed to pull and steer the
pallet truck only. Do not use the handle as a
leverage tool.
 WARNING
Do not attempt to move pallet truck with
forks in raised position. Lower forks
completely before moving pallet truck.
To raise forks, press the “Up” button in the
center of the handle, hold until desired height is
achieved, then release. The automatic brake
system featuring two axles (7) will engage the
floor to prevent movement.
To lower forks, press the “Down” button, hold
until desired height is achieved, then release.
The forks can be stopped at any position and
will hold firmly in place.
The pump assembly features an overload safety
valve. When the pallet truck lifts beyond its
maximum capacity, only the mid-cylinder (413)
will extend out fully; the piston rod (406) cannot
extend.
If pallet truck is overloaded, the mid-cylinder
(413) only will rise. The pison rod (406) will not.
Avoid pushing the "Up" button when overloaded
to prevent any damage to the pump station.

5
If the lifting speed becomes too slow, the battery
needs to be charged. Proceed as follows:
1. Lower forks, remove screws (32) and metal
cover (30).
2. Plug charger power cable (271) into a
standard 115V single phase wall socket.
3. Connect charger outlet cable to socket (225)
located in the electrical control case.
4. Normal charge time for battery is 4 to 5
hours. A yellow light on the voltage meter
(283) indicates battery is charging.
5. Full charge may take up to 16 hours if
battery is completely dead.
6. Do not operate while charging the battery.
Maintenance
After lowering forks, check hydraulic fluid level
visually in plastic tank located under pump
station assembly (220).
Proper hydraulic fluid level is approximately 1"
from bottomof tank. If hydraulic fluid level is
less than 1", add high quality hydraulic fluid or
hydraulic jack oil.
