1 SAFETY INSTRUCTIONS

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. The unit may be loaded with weights up to 5000 lb. However we advise you not to move any
weights above 1650 lb. (750 kg) with the unit. RAVAS is not responsible for injury that may
result when moving heavy loads.

4. Use caution in the vicinity of moving parts - these parts can cut and/or crush hands, arms, feet
and legs.

5. Always center the load you are lifting on both the forks.

6. Do not operate the weighing system on ramps, inclines or declines, without the addition of our
optional parking brake.

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

8. All modifications must be approved in writing from the supplier, prior to any work being
completed.

9. It is the sole responsibility of the purchaser to train their own employees in the proper use and
maintenance of this equipment.

10. Do not operate this unit unless you have been fully trained of its capabilities.

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

12. Do not carry passengers with the truck.

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

14. Do not lift unstable loads.

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

16. Only trained and authorized personnel are allowed to operate the truck.

17. Always follow the operating, maintenance and repair instructions of this truck and ask the
supplier when in doubt.

18. Never lower loads if you are unsure you can place the goods on a stable surface. Personal
injury may result from placement on an unstable environment.

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

20. RAVAS is not responsible for errors that occur due to incorrect weightings or inaccurate
scales.

2 SYSTEM SETUP

Make sure the lever is pushed down to
the “pump” position.

Thread the chain through the hole in the
triangle and through the hole in the axle.

Place the handle bar onto the triangle and
insert the bolts.

Tighten the bolts firmly.

Push the silver part “A” on the outside of

the pump downwards.
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).

When the voltage level of the battery is running low, the display
will show “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 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 on 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 overload the battery because the charger shuts off automatically.

3.1 USING THE WEIGHING HAND PALLET TRUCK

-2



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.

7

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 has been

executed. (See Chapter 5)

MAINTENANCE
The maintenance guidelines for normal pallet trucks apply to the chassis of the

mobile scale. The integrated scale will still function even though the chassis has
been 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 sealings.

- The scale meets up to the protection class NEMA 4/IP65. This means that dust or
moisture (rain or water beam from all sides), will not influence the operation of the
electronics. However, high-pressure cleansing in combination with warm water or
chemical cleansers will lead to the entry of moisture and have a negative influence
on the operation of the system.

- To avoid damage to load cells and electronics only specialists may undertake any
welding.

- The bearings of the wheels (non-polyurethane) and the pivoting points of the
levelling bar of the loading wheels must be cleansed and greased regularly.
