SAFETY SYMBOLS
WARNING and CAUTION are both signal words intended
to alert the viewer to the existence and relative degree
of a hazard. They are both preceded by a safety alert
symbol consisting of an exclamation mark enclosed by
a triangle.
A warning indicates a hazard that could result
in injury or death if proper precautions are not
taken.
A caution indicates a reminder of routine safety
practices.
SAFETY PRECAUTIONS
WARNING! Do not operate this truck unless you
have been trained and authorized to do so, and
have read all warnings and instructions in the
operators manual and on this truck.
WARNING! Do not operate this truck until you
have checked its condition. Give special
attention to the wheels, horn, battery, controller,
lift system, brakes, steering mechanism, guards
and safety devices.
WARNING! Operate the truck only from the
designated operating position. Wear foot
protection. Do not carry passengers.
WARNING! Observe applicable traffic
regulations. Yield right of way to pedestrians.
Slow down and sound horn at cross aisles and
wherever vision is obstructed.
WARNING! Start, stop, travel, steer and brake
smoothly. Slow down for turns and on uneven
or slippery surfaces that could cause the truck
to slide or overturn. Use special care when
traveling without load as the risk of overturn may
be greater. Always look in the direction of travel.
Keep a clear view, and when load interferes with
visibility, travel with load or lifting mechanism
trailing.
WARNING! Use special care when operating on
ramps. Travel slowly and do not angle or turn.
Travel with the lifting mechanism downhill.
WARNING! Do not overload truck. Check
capacity plate for load weight and load center
information.
WARNING! Do not handle loads that are higher
than the load backrest or load backrest
extension, unless load is secured so that no part
of it could fall backward. Before lifting, be sure
load is centered, forks are completely under
load and load is as far back as possible against
load backrest.
WARNING! When leaving truck, neutralize travel
control, fully lower lifting mechanism and set
brake when leaving truck unattended. Also, shut
off power.
MOVING A DISABLED TRUCK
WARNING! Do not attempt to move a disabled
truck; notify your supervisor or proper authority.

GENERAL DESCRIPTION
H-4709 and H-4710 pallet trucks lift and transport loads
on rigid forks.
Controls for steering, braking, forward and reverse travel,
horn, lift, lower and speed control are all located on the
control handle.
NAMEPLATE AND WARNING DECAL
Nameplate and warning decal locations may vary
between models, but they are always near the steering
arm, within sight of the operator.
(See Figure 1 for H-4709 and Figure 2 for H-4710)
If the name plate or warning decal are lost or
damaged, they should be replaced immediately. Have
your supervisor or the designated authority contact
Uline for replacement.
The name plate shows the model number, serial number,
truck type, battery type, voltage, minimum weight and
information on load capacity and load center.
The warning decal contains warnings that also appear
in this manual.
WARNING! This truck is equipped with a battery.
Read and heed the warning decal located
near the battery. An example is shown here:
LOAD CAPACITY
Do not overload truck. Check capacity plate for load
weight and load center information.
The load capacity depends on the load center. The
load maximum capacity listed on the capacity plate
assumes a uniform load whose center is at 1/2 the
length of the fork and centered between the forks.
The maximum load capacity is reduced when the
load center exceeds 1/2 the length of the forks or is
not centered between the forks. The fork length and
wheelbase must be adequate for the skid or bin to be
handled. (See Figure 3)
NOTE: A truck undergoing speed changes is less
stable than a standing truck. If you are not sure
that the truck can lift a certain load, consult your
supervisor or the designated authority.

BEFORE OPERATION
The Operator Checks table below covers important
inspection points on trucks that should be checked
prior to operation. Depending on use, some trucks may
require additional checks.
WARNING! Periodic maintenance of this truck
by a qualified technician is required.
WARNING! A qualified service technician
should check the truck monthly for proper
lubrication, proper fluid levels, brake
maintenance, motor maintenance and other
areas.
WARNING! If the truck is found to be unsafe and
in need of repair, or if it contributes to an unsafe
condition, report immediately to the designated
authority. Do not operate the truck until it has
been restored to a safe operating condition.
Do not make any unauthorized repairs or
adjustments. All service must be performed by a
qualified service technician.
OPERATION
OPERATOR CHECKS
ITEM PROCEDURE
Transmission and Hydraulic Systems Check for signs of fluid leakage.
Forks Check for cracks and damage.
Guards and Load Backrest Check that safety guards are properly secured and not damaged.
Safety Signs Check that warning labels, nameplate, etc., are in good condition and legible.
Horn Check that horn sounds when operated.
Steering Check for binding or looseness in steering arm when steering.
Travel Controls Check that speed controls on control handle operate in all speed ranges in forward and
reverse and that belly button switch functions.
Wheels Check drive wheel for cracks or damage.
Move truck to check load wheels for freedom of rotation.
Hydraulic Controls Check operation of lift and lower to their maximum positions.
Brakes Check that brakes actuate when steering arm is raised to upright position and when lowered to
horizontal position.
Deadman/Parking Brake Check that steering arm raises to upright position when released and that brake applies.
Battery Disconnect Check that battery can be disconnected and reconnected. Check for connector damage.
INSTRUMENTS AND CONTROLS
The steering arm and control handle provide controls
for steering, forward and reverse speed control, braking,
raising and lowering the forks and horn. Control handles
on all models have a “belly-button” reversing switch,
which reverses the direction of the truck upon contact
with the operator. (See Figure 4)
FORWARD AND REVERSE TRAVEL
AND SPEED CONTROL
All directional and speed controls are located on the
control handle.
Forward and reverse are controlled by rotating the
speed control lever. (See Figure 4) The lever is spring
loaded to return to neutral when released. Further
rotation in either direction will progress the truck from
slow to maximum travel speed.
To change directions or to stop the truck, rotate the
speed control lever in the opposite direction. The truck
will come to a stop, and then (unless the controls are
returned to the center neutral position) accelerate in the
opposite direction.
STEERING
Moving the control handle (which connects to the
steering arm) right or left will turn the truck right or left.
When maneuvering around corners, make square turns
and be sure there is adequate clearance.

OPERATION CONTINUED
STOPPING
Stop the truck as gradually as possible. Unnecessary
rapid stopping could be hazardous. Load could
become unstable.
To stop the truck's movement (forward or reverse), raise
the control handle to the up position or push the control
handle all the way down. In both positions, the electric
brake will deactivate and the brake will apply. To
release the brake, just move the control handle to the
operating position. (See Figure 5)
NOTE: The steering arm gas spring
automatically raises the steering arm to the
upright position when the steering arm is
released.
CAUTION! If the control handle does not raise
immediately to the vertical position when
released, the truck should be placed out of
service until it can be inspected by a qualified
service technician.
PARKING
When parking the truck, do not obstruct traffic lanes or
aisles.
1. Park the truck in its designated parking area.
2. Raise the steering arm until vertical to apply the
parking brake.
3. Fully lower forks.
4. Turn key switch to off position.
5. Remove key for added security.
6. Pull out battery disconnect.
LOAD HANDLING
WARNING! Handle only loads arranged for
stability and always use caution. Raise and
lower the load smoothly to prevent the load
from falling.
WARNING! Always be sure the load and load
center are within the capacity of the truck. If in
doubt, check the nameplate.
1. Approach the load slowly.
2. Move the truck slowly into position so that the forks
are within pallet or skid, and the load is centered
over the forks and as far back as possible.
3. Raise the forks to lift load.
4. Lead the truck by the control handle with the load
trailing except when in confined areas. Ramps
should be traveled with operator uphill of truck when
empty, or operator downhill of truck with load on
forks.
5. Always look in the direction of travel. Move slowly
and check clearances when approaching
obstructions.
6. Do not make sudden starts and stops. Operate truck
smoothly and gradually.
7. Travel slowly and squarely around corners.
Remember that the trailing load wheels do not
follow the turn path of the drive wheel. Instead, they
tend to cut the corner.
8. Line up the truck with the unloading area.
9. Stop the truck and check the load alignment with
surrounding objects.
10. Be careful not to damage or move adjacent loads
and objects.
11. Lower the forks until the load is resting on its own.
12. Move the truck back until the forks are clear of the
pallet.
