OPERATION

WARNING! Operator must read and understand instructions here and on truck prior to use.

On the handle of the pallet truck, you will find the control lever which can be set in three positions. (See Figure 1)

Figure 1

Technical diagram showing a mechanical component with three directional control icons labeled P, P1, and P2.

• LOWER = to lower the forks
• NEUTRAL = to move the load
• RAISE = to raise the forks

If the forks elevate while pumping in the NEUTRAL position, turn the setting screw clockwise until pumping the handle does not raise the forks and the NEUTRAL position functions correctly.

1. If the forks descend while pumping in the NEUTRAL position, turn the setting screw counterclockwise until the forks do not lower.
2. If the forks do not descend when the control lever is in the LOWER position, turn the setting screw clockwise until raising the control lever lowers the forks. Then check the NEUTRAL position as per steps 1 and 2.
3. If the forks do not lift while pumping in the RAISE position, turn the setting screw counterclockwise until the forks elevate while pumping in the RAISED position. Then check the NEUTRAL and LOWER position as per steps 1, 2 and 3.

NOTE: When viewing the truck from the handle side, the setting screw is located on the right side of the pump above the right wheel. The truck will lower faster or slower depending on how far in or out the screw is adjusted.

MAINTENANCE

HOW TO EXPEL AIR FROM THE PUMP UNIT

Air may enter the unit over time or when the seals are replaced. To expel the air, lift the control lever to the LOWER position and move the handle up and down several times.

DAILY CHECK AND MAINTENANCE

Daily checks of the pallet truck can limit wear and tear on the unit. Pay special attention to the wheels, the axles, the handle, the forks and lift and lower controls.

LUBRICATION

Use motor oil or grease to lubricate all moveable parts.

SAFETY

For safe operation of the Pallet Truck With Hand Brake, please read all warning signs and instructions here and on the pallet truck prior to use.

1. Do not operate the pallet truck unless you are familiar with it and have been trained and authorized to do so.
2. Do not use the truck on sloping ground.
3. Never place any part of your body in the lifting mechanism or under the forks or load. Do not carry passengers.

4. We advise that operators wear gloves and safety shoes.

5. Do not handle unstable or loosely stacked loads.

6. Do not overload the truck.
7. Always center loads on the forks, not at the end of the forks. (See Figure 2)
8. The capacity of the truck assumes an evenly distributed load with the center of the load being at the halfway point of the length of the forks.
9. Make sure that length of the forks matches the length of the pallet load.
10. Lower the forks to lowest height when the truck is not being used.
