WORK AREA
•Keep work area clean, free of clutter, and well-lit. Cluttered and dark work areas can cause
accidents.
•Keep children and bystanders away while operating a pallet truck. Distractions can cause you
to lose control, so visitors should remain at a safe distance from the work area.
•Be alert of your surroundings. Using a pallet truck in confined work areas may put you
dangerously close to sharp tools and rotating parts.
PERSONAL SAFETY
•Stay alert, watch what you are doing, and use common sense when using a pallet truck. Do not
use a pallet truck while you are tired or under the influence of drugs, alcohol, or medication. A
moment of inattention while operating a pallet truck may result in serious personal injury.
•Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair,
clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught
in moving parts.
•Use safety apparel and equipment. Use safety goggles or safety glasses with side shields that
comply with current national standards or, when needed, a face shield. Use a dust mask if
working in dusty work conditions. This applies to all persons in the work area.Also use non-skid,
safety shoes, hard hats, gloves, dust collection systems, and hearing protection when
appropriate.
PALLET TRUCK USE AND CARE
•Do not modify the pallet truck in any way. Unauthorized modification may impair the function
and/or safety and could affect the life of the equipment. There are specific applications for which
the pallet truck was designed.
•Always check for damaged or worn-out parts before using the pallet truck. Broken parts
will affect the pallet truck operation. Replace or repair damaged or worn parts immediately.
•Do not exceed the pallet truck load capacity.
•Distribute the load evenly. Uneven loads may cause the pallet truck to tip, resulting in
personal injury to the operator or others.
•Use the pallet truck on flat and level surfaces capable of supporting the pallet truck and its
maximum load. Pulling or pushing a load on a slanted or uneven surface can result in loss of
control.
•Store idle pallet truck. When the pallet truck is not in use, store it in a secure place out of the
reach of children. Inspect it for good working condition prior to storage and before re-use.

2. The Screw (9) (see Figure 4) is used for the adjustment of the truck. If the truck body drops
immediately after it is lifted, turn the Screw (9) slightly counterclockwise before trying the
truck again. If the truck body will not lower, turn the Screw (9) slightly clockwise. Then try to
operate the truck again till the truck is able to lower normally.

truck lower slowly. Never release the Trigger quickly. Rapid descent will damage the truck
and the cargo.
2. Do not exceed the truck load capacity.
3. The center of gravity of the goods should be positioned in the middle of the two forks –see
Figure 5.
