SAFETY PRECAUTIONS

For safe operation of the weighing indicator, please

follow these instructions:

●Calibration inspection and maintenance of the indicator are

prohibited by non-professional staff

●Please ensure that the indicator rests on a stable surface

●The indicator is a piece of static sensitive equipment; Please

cut off power during electrical connections

●Touching the internal components by hand is prohibited

●DO NOT exceed the rated load limit of the unit

●DO NOT step on the unit

●DO NOT jump on the scale

●DO NOT use this product if any of the components are

cracked

●DO NOT use for purposes other than weight taking

●To avoid damaging the battery do not keep charger plugged

in once battery is fully charged

●Make sure the weight is not over the max capacity as it could

damage the load cell inside

● Material that has a static electric charge could inuence the

weighing. Discharge the static electricity of the samples, if

possible. Another solution to the problem is to wipe both

sides of the pan and the top of the case with an anti-static

agent

Please take anti-static prevention measures

Any accumulated charge on the body of the human operator

should be discharged rst before opening the protective contain-

er with ESDS devices inside. The discharge can be accomplished

by:

●Putting a hand on a grounded surface or, ideally, by wearing

a grounded Anti-static Wrist Strap and an Anti-static Mat

PREPARATION & SET UP

●Plug into a wall outlet to avoid interference with other wirings

●Turn on the indicator while there is no load

●Calibration may be required before weighing when the scale

is initially installed or moved from a location

FEATURES

The indicator is designed for the motorized forklift truck scale

application. The instrument has a friendly interface, simple opera-

tion, stable performance, and uses minimal energy.

PART DESCRIPTIONS

MOTORIZED PALLET JACK

INSTRUCTIONS

●Unplug the motorized pallet jack from its charger.

●Lower the forks to the ground using the buttons on the handle.

●Use the controls on the handle to maneuver the pallet jack backward

and forward.

●Use the handle its self to steer the pallet jack left or right.

●Line up the forks of the pallet truck with the pallet.

●Move forward to slide the forks into the pallet openings.

●Use the controls to lift the load off the ground. Unlike non-motorized

pallet jacks, you don’t have to manually pump motorized ones.

●Press the forward buttons and use the handle to steer. Direct the elec-

tric pallet jack to the location where you want to unload the pallet.

●Once you’ve arrived to the spot where you want to unload the pallet,

come to a complete stop by easing off the controls before lowering the

forks. Lower the forks to the ground all the way.

●Move the pallet jack backward to remove the forks from the pallet

openings.

●Now, you’re ready to pick up the next load!

●When you’re done using the motorized pallet jack, maneuver it back to

the charging station and plug it in. That way, it’s powered for the next

use.

POWER SUPPLY

Pallet Jack Adapter

The power cord for your pallet jack is located on the top right

shoulder of the jack. We recommend to plug into a wall outlet to

avoid interference with other wirings.

Indicator charge lasts up to 22 hours

Battery Charge time: 8hrs

Battery run time: 6hrs continuous

Battery Voltage: 12V

Battery weight: 100lb

Battery Rated Capacity: 75Ah

Indicator Battery

The indicator is charged through the pallet jack adapter. To keep

the battery in best condition, fully discharge the battery every

month by leaving the indicator on until the indicator powers off,

and then recharge fully. If the battery is not going to be used for a

long period of time it is recommended to remove it to avoid leak-

age.

TOTAL 1. Accumulates weights

2. Works with SET key to perform the Accumulation function and

check the Accumulation result

UNIT Shifts between weighing units, KG and LB

ZERO 1. Zero’s the scale within zero range

2. Tare’s the weight if it’s over the zero range

SET 1. Long Press to print the weight

2. Combined with ON/OFF to enter into calibration

3. Combined with the TOTAL key to check the Accumulative sum

lb The weight is shown in pounds

kg The weight is shown in kilograms

Hold Shows you are in Hold mode

Gross Shows you are in Gross weight mode (includes tare); default

mode

Net Shows you are in Net weight mode (weight without tared weight)

Tare Displays tare status

The scale is stable

The scale is at zero

OPERATING INSTRUCTIONS

Power On

●Turn on the power by pressing the power button for 3 sec-

onds. Once on, the scale will ash the voltage and then begin

to auto-check and count down from 0-9

sequentially before entering the weighing mode

Note: Anything on the scale before powering on will auto-

matically be tared out

Zeroing

●The zero function is used only when the scale is empty and is

not at gross zero due to material build up

●Pressing the ZERO key will reset your scale to 0

●Depending on what your manual zero range parameter is set

to, you can zero out any number within your set selection,

after that you will receive an error and will need to tare out

the weight

Tare Function

●The Tare function is used when you only wish to see the cur-

rent change in weight, not the entire amount of weight that

is on the scale

●When the indicator is in gross mode (gross light is shown)

pressing the ZERO key will Tare the current weight on the

scale and enter the net mode (net light shown)

●For example, if you are using a pallet add the pallet to the

scale, press tare and the display will show the tare symbol

and reset back to 0

●Add your product to the scale to weigh without the weight of

the pallet

●To exit Tare mode press the ZERO key again to enter gross

mode and you will see the total weight of the pallet and the

product

Note: If you remove the pallet the scale will show the minus weight

of the pallet
