Dear customer,
Thank you for purchasing a DINI ARGEO product.
This manual explains the usage of the hydraulic weighing system for forklift trucks.
In particular, zero, tare and all the function of the weighing electronic are described, to assist the forklift driver during use.
For any additional information or specific requests, please contact your local dealer.
This publication is optimized for A4 printing.
Introduction
• The weighing system does not change the safety regulations normally applied to the forklift truck.
• Before weighing, make sure that the lift truck is stationary, on a flat surface and that there are no people in the area around the load.
• The employee training on the use of the system is the purchaser’s responsibility.
• Please read this manual carefully before using the system.
• Assistance must only be carried out by personnel authorized by Dini Argeo.
• Dini Argeo is not responsible for any weighing errors resulting from improper use of the system.

The system is based on the measurement of the oil pressure contained in the hydraulic lifting circuit by means of a specific sensor. This
pressure depends on the load on the forks and the height of the forks themselves, which is why the weighing operations must always be
carried out at the same height (indicated by the stickers).
The theoretical precision of the LTP system, correctly installed on suitable forklifts and used under optimal conditions, varies from
0.5% to 5% of the capacity (min. 20 kg).
This accuracy is adversely aected by the following factors:
Type and state of wear of the forklift.
- 10° C
+ 50° C
Ambient temperature: the temperature range of the sensor is from - 10° C to + 50° C.
Mechanical friction: keep sliding parts clean and lubricated.
Oil leaks.
Load position on the forks: the gravity centre of the load must be positioned in the centre of the
forks.
Tilt of the forks: for proper weighing, position the forks at 90° to the ground.
Lifting speed: lift the load at a constant speed and without sudden dashes so as to avoid jolts.
Position of the sensor inside the hydraulic circuit. Refer to the technical manual for sensor instal-
lation.
Type of oil in the hydraulic circuit: use oils with low viscosity and suitable for a wide temperature
range.

Weight reading
Before turning on the indicator, make some lifting with empty forks (at least 5) to heat the oil temperature inside the hydraulic circuit.
With the forks down (without touching the ground), turn on the weight indicator and wait for it to zero.
During load acquisition the display shows: ----
At the end of the acquisition, the weight is shown.
Between weighings it is necessary to return the weight to 0 by unloading and lowering the forks.
