BEFORE YOU BEGIN

Always follow your facility's rules regarding wearing Personal Protective Equipment such as safety

shoes and protective glasses whenever operating, working with, or assembling or dismantling

hand pallet trucks.

DELIVERY INSPECTION

Visually inspect the frame components and hydraulic unit for damage during shipment by carrier. If

damage is evident, notify delivering carrier immediately and file necessary claims. Test the manual

pump for proper operation. If the hydraulic pump does not respond to movement of the

handle, an air lock may have developed during shipping. To remedy this, go to the user

friendly TROUBLESHOOTING guide in this manual.

OPERATING INSTRUCTIONS

(Read and understand prior to using this product)

To raise the load, push

down on the fingertip

control. Pump the

handle to raise the load

from the floor.

NOTE:

The neutral position

disengages the pump from

the lifting mechanism. This

frees the handle, which

makes pulling loads easier.

In addition, the pump is

not subject to shock

pressures while the truck is

in motion.

To lower the load, pull

up on the fingertip

control.

For free handle

movement, place the

fingertip control in the

neutral position.

SAFETY

(read and understand prior to using this product)

• Read and obey all labels on this product. If you have any questions about these, ask your

supervisor.

• Do not operate this hand pallet truck unless you are authorized and trained to do so.

• Never overload your hand pallet truck. Stay within its rated capacity.

• Do not operate this truck if damaged or not in proper working order.

• Distribute the load evenly on the forks. Do not concentrate loads at one point or load one fork

more than the other.

• When the load impairs visibility, the hand pallet lift truck should be pulled and not pushed.

•Alwayslook where you are operating. Keep a clear view.

• Only handle loads on flat level surfaces. Do not use a loaded truck on inclines or declines.

• Never carry passengers.

• Never put your feet, hands, or any other body part under the frame assembly.

• Always yield right of way to pedestrians.

• Do not allow your hand pallet truck to drop from one level to another. Even a drop of 1 in.

(25 mm) more than doubles the effective load momentarily and results in a loading that can

bend or break components.

• Move loads only with the hand pallet truck in its lowest position.

•Alwaysmake sure that the load is stable before moving to eliminate the opportunity for load

shift.

• Use extreme care when rounding corners. Too fast a speed could cause a hand pallet lift truck to

tip. If loaded, the load could shift and fall.

• When not in use, fully lower the forks.

• Never lift a heavy load with just the points of the forks. This could damage the electronic

weighing elements permanently.

• Never weigh without a pallet. This could affect the accuracy of the weighing result.

• The unit may be loaded with weights up to 5000 lb. (2268 kg).

• Do not operate the weighing system on ramps, inclines or declines, without the addition of our

optional parking brake.

• Do not operate the weighing system while others are on or near the unit. No riding!

• Do not use the weighing system in potentially explosive areas.

• Do not weld or make changes to the weighing system without consulting the supplier.

• Check the accuracy of the scale on a regular basis to prevent faulty readings.

• Never lower loads if you are unsure you can place the load on a stable surface. Personal injury

may result from placement on an unstable environment.

• Always remain with the scale during dosing applications. Incorrect lifting of the pallet can cause

overflowing.

• Lift-Rite is not responsible for errors that occur due to incorrect weights or inaccurate scales.

SYSTEM SETUP

Mounting the Pump Handle

1. Make sure the lever is pushed down to

the “pump” position.

2. Thread the chain through the hole in the

triangle and through the hole in the axle.

3. Place the handle bar onto the triangle

and insert the bolts.

4. Tighten the bolts firmly.

5. Push the silver part “A” on the outside of

the pump downwards.

6. At the same time; insert the chain into

the open side of the slot “B” on the

inside of the pump.

The Battery

The power supply to the system takes place through an exchangeable battery pack. A completely

charged battery should operate for a total weighing time of about 35 hours (on a system without a

printer).

CAUTION! - When the voltage level of the battery is running low, the dis-

play shows “LO-BA”. When the battery is completely empty, the weighing

system shuts off.

It is necessary to charge the battery for at least 6 hours before the first use. Recharge the battery

when the LO-BA indicator comes on.

If you use the system in shift work or if the system has a built-in printer, it is recommended to

purchase a supplementary battery pack.

The battery should be charged using the adapter supplied with the charger. When the battery is

charging, the LED on the charger is lit. When the LED turns off, the battery is fully charged.

It is not possible to overcharge the battery because the charger shuts off automatically.

OPERATION MANUAL

USING THE WEIGHING HAND PALLET TRUCK

Accurate Weighing

The weight must be centered over the forks of the pallet truck and lift freely: without touching the

housing of the indicator or other pallets.

Fast temperature changes should be avoided because condensation may form in the electronics.

During acclimatization the indicator must be turned off.

Taking the System into Operation

To activate the scale, turn it on using the on/off () button on the terminal.

After 3 to 5 minutes the electronics and load cells have reached the operational temperature. Before

this, inaccuracies of up to 0.3% may occur.

It is recommended not to lift loads before the zero-point correction is executed. (See

“TROUBLESHOOTING” on page 20).

Maintenance

The maintenance guidelines for normal pallet trucks apply to the chassis of the mobile scale. The

integrated scale functions even though the chassis is damaged by overloading.

Main guidelines:

• Because the steering wheels are mounted in the front, pulling of the pallet truck is preferred

above pushing it.

• When the lifting mechanism is not used, the handle should be kept in the neutral (middle)

position. This prolongs the life-span of the seals.

• The scale meets up to the protection class NEMA 4/IP65. This means that dust or moisture (rain

or water beam from all sides) does not influence the operation of the electronics. However,

high-pressure cleansing in combination with warm water or chemical cleansers leads to the

entry of moisture and has a negative influence on the operation of the system.

• To avoid damage to load cells and electronics, only the Authorized Service Center may

undertake any welding.

• The bearings of the wheels (non-polyurethane) and the pivoting points of the leveling bar of the

loading wheels must be cleansed and greased regularly.

TOUCH PANEL INDICATOR

There are three display-modes: lbs., kg, or the number of pieces.

Also, the battery sign is integrated in the display to show a low battery status.

Indicator Front

The Display

By means of eight pointer bars the display shows:

the scale (including load) is stable

the weight shown is negative

ZERO the weight shown is within the zero range

NET the display is showing the net weight

e1 the weight shown is in range 1

e2 the weight shown is in range 2

e3 the weight shown is in range 3

stp Set-point 1 is activated

stp2 Set-point 2 is activated

The Touch Panel

Each key has two operational and one entry function.

IMPORTANT

Operation of a key is not accepted unless the scale is stable (and the “load stable” pointer

lights up). This means that the indicator only executes commands with a stable load.

INDICATOR FUNCTIONS

Graduation

From 0 to 3000 lbs. (0 to 1361 kg), the weight is shown in 1 lb. (0.5 kg) increments.

From 0 to 5000 lbs. (0 to 2268 kg), the weight is shown in 2 lb. (0.9 kg) increments.

Before Weighing: Check Zero Point

Before each weighing, it is necessary to check whether the system is unloaded and free. The

indicator is fitted with an automatic zero correction. This means that small deviations of the zero

point corrects automatically. If the indicator does not determine the zero point automatically, it must

be done manually by pressing the >0< key.

Gross Weighing

After lifting a load, the display shows the gross value of the weighed load.

Net Weighing: Automatic Tare

The indicator offers the possibility to reset tare weights to zero automatically. This way added or

subtracted weights can be determined.

•Liftload.

• Press key .

• The indicator is set to zero.

• The "NET" pointer shows that a tare weight is activated.

• Place or remove the net load.

• The display shows the net value of the weighed load.

• When load is removed, a negative weight is shown.

• By pressing the key again, the gross weight is shown.

Tare Weights

A tare weight can be entered at any time, either in a loaded or unloaded situation.

Sample Tare Entry

• Pick up the empty pallet, container, or item that you want to delete from the Net Weight.

• Tap the “T” Tare Button.

• Indicator shows “0” zero.

• When the Weighing Hand Pallet Jack is emptied/off-loaded, the indicator shows the negative

Tare Weight.

• Tare Weight saves until the system is re-zeroed.

• To delete the Tare Weight, empty the Weighing Hand Pallet Jack and tap the “0” zero button.

• Press the key until the display changes and the last digit is flashing (approx 3 seconds).

• The display shows the current tare value.

• The right digit flashes.

• Press the key to go up a value or press the key to go down a value until the required

value is reached for that place.

• Press to change to the next digit.

• Repeat this procedure until the required tare value is shown.

• Press ENTER ( ) to activate the tare weight.

• The tare weight activates.

• The “NET” pointer lights up.

• When the system is loaded, the net value is shown in the display

• When the system is unloaded, the read-out shows the negative value of the given tare.

• The entered value remains active until a new tare weight is entered (display shows the new

net weight).

• Press the key to return to gross weighing mode.

Piece Count: Sampling

If an unknown piece weight is to be determined, you may do this by sampling a certain number of

pieces. The number of pieces taken from or placed on the scale determines the accuracy of the

sampling. The total weight of the pieces taken from or placed on the scale for the sampling should

be no less than 9 to 10 lbs. (4.1 to 4.5 kg). The greater the weight difference, the greater accuracy.

The standard sampling amount is 10 pieces, but this number can be increased up to 95 pieces.

• Press the key.

• The display shows “add10”. The “lb.” pointer changes to “pcs”.

• Take or place 10 pieces from/on the scale and press the ENTER ( ) key.

• The sampling is done and the display shows the total number of pieces on the scale.

• Press the key or the key to change the number of pieces to add.

• The display shows the new value to add. (For example “add 50”).

• Take or place 50 pieces from/on the scale and press the ENTER ( ) key.

• The sampling is done and the display shows the total number of pieces on the scale.

To return to the normal weighing mode, press the key for 3 seconds.

Piece Count: Enter a Piece Weight

• Press the key for 3 seconds.

• The last used piece weight is shown with the right digit flashing.

• Press ENTER ( ) to accept the old value.

• The display shows the number of pieces currently on the scale.

• Change the piece weight value by using the or and keys.

• The display shows the new piece weight.

• Press ENTER ( ) to accept the new value.

• The display shows the number of pieces currently on the scale.

To return to the normal weigh mode, press the key.

Summing

The indicator offers the possibility to add weighings and show the total weight. When a tare weight

is active, the net weight is added automatically.

• Load the system with the weight that should be added.

• Press the key to add the weighed load to the total weight.

• The display shows the message “ADDED” and after a short delay returns to the weighing

mode.

NOTE: Note that no weight can be recorded twice. The system needs to be returned to the net

zero-range before another weight can be added up.

Press the key for 3 seconds to check the subtotal.

• The display shows the net total weight and the number of weights totaled so far repeatedly for

3 seconds.

• If the key is pressed during this period, the total is printed out (if option is installed) and

reset to 0.

• If the “CE” key is pressed during this period, the total is reset but not printed out.

• If no key is pressed during this period, the subtotal stays in memory and the system returns

to the weighing mode after 60 seconds.

Change Units

The system is set to start up in ‘lbs.’ instead of ‘kg’. However you may, at any time in the weighing

mode, change to the second unit (lb. kg or kg lb.).

• Press the key for 3 seconds.

• The display shows the current weight in the new units for 5 seconds and then automatically

changes back to the start up units.

NOTE: The same key is used to change from the piece counting mode back to the weighing mode.
