SPECIFIC OPERATION WARNINGS
WARNING: NEVER OVERLOAD!! Make sure the operator be familiar with the cart controls
before being authorized to operate it.
WARNING: DO NOT LIFT PERSONNEL. DO NOT LIFT LOADS OVER PEOPLE.
WARNING: DO NOT walk under a suspended load. DO NOT perform any work on a
suspended load that requires a worker to be positioned under the suspended load.
•Do not use damaged cart or cart that is not working properly.
•Use only on a hard, level surface.

Page 4 of 9
•Do not exceed the rated capacity 1000lbs.
•Before moving the load, assure that the load is centered and a load-restraining device is
recommended to secure the load. DO NOT move unstable loads.
•Do not use on sloping ground.
•Do not move the cart when loading in a raised position of height above 11.8in.
•Do not randomly regulate the safety valve.
•Do not allow people to sit or ride on the cart.
•Do not transport the loads during the lifting process.
•All maintenance is to be performed by professional personnel strictly in accordance to the
related information in this manual.
•Make sure all persons stay clear of the supported load.
•Keep feet and hands away from under the lowering table. Safety shoes should be worn during
operation.
•Make sure that all nuts, bolts and split pins are sufficiently fastened.
OPERATION INSTRUCTIONS
WARNING: Before use, check any broken or loose parts.
(1) Before operating, be sure the load is centered and stable on the platform.
(2) To lift the load on the cart, continue stepping on the foot pedal as the platform rises to the required
height.
(3) To lower the load on the cart, turn the Star Handle slowly and gently until the platform is lowered to
the desired height.
WARNING:
People will be seriously hurt or the cart will be damaged if turning the Star Handle quickly when
lowering the load.
Never shut off the oil return valve sharply, or the cart and/ or loads can be damaged.
Leaving the cart: Whenever the operator leaves the cart, the platform must be fully lowered.
Visibility: The operator must always have a clear view of the path in the direction of travel.
Load handling: Only stable and safely arranged loads within the rated capacity of the cart should be
handled. Operators are not to pick up and move loads that are too heavy. If, upon attempting to lift the
load, the rear wheels of the cart begin to rise, set the load down immediately and obtain proper
equipment to lift a load of that size.
When picking up a load, center the load evenly on the platform, (The load center position is showed in
TECHNICALSPECIFICATION section), and engage loads securely and stably.
Loads can be of many sizes and descriptions, such as boxes, bags, packages, or other small objects.
All loads should be made stable by either interlocking the objects, or strapping or shrink-wrapping the
load, to prevent individual objects from falling off the cart.
Long loads reduce the stability of a cart. Long, wide, or high loads require more room, so watch the
clearance. The load may be very secure until something is run into that shifts the cart’s center of gravity.
This creates the potential for a lateral overturn. Lifting long loads that extend directly in front changes
the weight center of the cart and reduces the lifting capacity of the cart. When right angle stacking or
moving with a low raised load to clear low objects, move very slowly and avoid sharp turns.
WARNING:
The length of cargos handled must be less than 35”, while width less than 36”.
Do not move with loads raised higher than 11.8”, and move with a low raised load just for short
distance.
Move very slowly and avoid any turns when moving with a raised load.

Operating surfaces: Operate the cart only on level surfaces. Make sure the surface will support the
weight of the vehicle and loads and not create unstable conditions before entering the area.
WARNING: Do not use on grades, ramps, slopes, and inclines.
Pedestrians: The operator of the cart is responsible for operating in a safe manner; this includes
avoiding all pedestrians in the work area.Always face the direction of travel.
Watch for people in the work area because they may not watch for the cart. If it is determined that they
may not see the lift cart, do not move until eye contact is made. If the view is blocked because of the
load, travel backwards. If the lift cart must move forward, make sure that people are out of the way and
move the cart slowly.
Watch for employees working in the same area. Do not let anyone walk under raised forks or load. If
someone is required to hold or position the load while the lift cart is moving –STOP. There is something
wrong. If unable to handle the load alone, change the load or the equipment. Otherwise, someone will
eventually be hurt badly. Do not take this risk. Find a better way to move the load.
Cart tipover: Lift trucks can be tipped over if not operated properly. Observe the following procedures
to lessen the possibility of a tipover.
Slow down before turning. Go into and out of turns slowly, using a slow rotation of the steering
wheel.
Drive with the platform lowered and the load stabilized. Raising a load high moves the center of
gravity and lowers the capacity.
Check capacities –do not overload the cart.
Do not move unstable loads.
Check your overhead clearance. Keep the cart at least 10 feet from any overhead electrical wires.
Watch for overhead obstructions like pipes and low doors. If they are hit while moving, the cart can
tip over.
Turning with the loaded platform raised can tip over the cart even at slow speeds.
Take the time necessary, slow down, and operate safely.
MAINTENANCE
Only use clean hydraulic oil, always keep enough hydraulic oil in the system.
Replace hydraulic oil on a yearly basis.
The air may come into the hydraulic oil because of transportation or pump in upset position. It can
cause that the platform do not elevate while pumping. The air can be banished by stepping on the
foot pedal up and down for several times.
Daily check of the pallet truck can limit wear as much as possible, special attention should be paid
to the wheels, the axles, as thread, rags, etc. It may block the wheels. The cart should be unloaded
and lowered in the lowest position when the job is over.
Use motor oil or grease to lubricate all movable parts.
