2.1 Operator should read all warning signs and instructions here and on the pallet truck before using this truck.

2.2 Do not use on a slopping surface.

2.3 Do not operate a pallet truck unless you are familiar with it and have been trained or authorized to do so.

2.4 Do not operate a pallet truck unless you have checked its condition. Give special attention to the wheels or rollers, the draw-bar unit, the fork unit, the lever plate, etc.

2.5 To pull the truck, always move the control handle into the drive position. This makes the draw-bar easier to move and depressurizes the pump section of the hydraulics. This preserves the hydraulic seals and the valve components. A long service life can be expected.

2.6 Do not take up any people on the pallet truck.

2.7 The operator should wear safety shoes and gloves for protection against crushing or cutting hands and feet. Keep feet from being underneath the load at all times.

2.8 While the goods are being transported, all people should stay min. 2 feet away from the load.

2.9 Do not load beyond maximum capacity.

2.10 Do not use the truck in a potentially explosive environment.

2.11 Do not use the truck as a vehicle jack.

2.12 Do not use during strong wind forces.

2.13 The truck shall not have direct contact with perishables.

2.14 Do not use the truck on places insufficiently illuminated.

2.15 In unknown environment, the operator should be careful while operating the pallet truck.

4.4 Battery Replacement

①Battery Holder②Battery Cover

The instrument is provided with 2 CR2447 button cells.

As shown in Figure 4-3, it is necessary to slide down instrument battery cover to remove the used battery for replacement; put the new battery into the battery holder, and then close the battery cover.

Be sure to replace the battery if power monitoring icon as displayed is blank, and data displayed is indistinct.

It is better not to put the instrument into prolonged operation in case of rain and snow; prolonged exposure of instrument to the sunshine is strictly prohibited.

It is applicable to clean the instrument shell with soft and clean rag in combination with routine washing solvent; never use industrial solvent for cleaning or directly spray it on the instrument surface.

Users are recommended to check the instrument and sensor regularly to ensure its accuracy during use.

6.1 System Halt This product has received strict testing before delivery and no system halt will occur under normal conditions. Please remove the battery, and refit it again to recover its normal operation in case of system halt.

6.2 Start-up Failure

6.2.1 Power run-out Disassemble the gauge outfit, and use a voltmeter to measure battery voltage; if the voltage is below 3.5V, it means that battery voltage is extremely low, which may result in start-up failure; replace the old battery with new one in this case.

6.2.2 Battery connecting line disconnected Disassemble the gauge outfit, and use a voltmeter to measure battery voltage; if the voltage is over 3.5V, just check if the red-black connecting line between battery module and instrument panel is disconnected.

6.2.3 Other problems Please contact professionals for testing of panel if power supply is normal.

6.3 Abnormal Display

6.3.1 Unit switch unit switching key for “unit switching” to check If the sensor is proved to be normal through test, just press if the data displayed is normal.

6.3.2 Sensor connection If display of instrument reading is abnormal, just turn off the machine and turn on it again to check screen display; if “SSERR” is displayed on the screen following display of “SS CK”, it means that connection of sensor is abnormal; in this case, it is necessary to check if connection between the sensor and instrument panel is normal before contacting professionals to check if sensor output is normal.

6.3.3 Calibration If abnormal data is still displayed by the instrument following unit switching, just use “unit switching” and “tare removal” in combination to enter the parameter setup mode, and recalibrate at the final setup option (for details, please refer to 8)
