1. Instruction manual
1.1 Range of application
Please use and maintain the scale pallet truck according to this instruction manual.
Operations that are not listed in this manual may cause harm to the operator or the
scale pallet truck, and may cause property damage. Please read the name plate before
use, and make sure that the load isn’t overweight. Please avoid unbalance load.
Flammable, explosive, and humid environment may cause explode or short circuit of
display.
1.2 Operational order
The scale pallet truck should be operated by well trained person, who knows how to do
loading, is clear about contents in this instruction manual, and masters operating skills.
All users should read and understand contents of this instruction manual. The
manufacture will not be liable for any damage resulting from failure to comply with this
instruction manual.
1.3 Safety precautions
1) Never lift a heavy load with just the points of the forks. This could damage the
electronic weighing elements permanently.
2) Never weigh without a pallet. This could affect the accuracy of the weighing result.
3) Use caution in the vicinity of moving parts—these parts can cut and/or crush hands,
arms, feet, and legs.
4) Always center the load you are lifting on both forks.
5) Do not operate the weighing system while others are on or near the unit.
6) It is the sole responsibility of the purchaser to train their own employees in the
proper use and maintenance of this equipment.
7) Do not use the weighing system in potentially explosive areas.
8) Do not carry passengers with the truck.
9) Do not lift unstable loads.
10) Check the accuracy of the scale on a regular basis to prevent faulty readings.
