maintenance of this equipment.
7. Do not operate this unit unless you have been fully trained of its capabilities.
8. Do not use the weighing system in potentially explosive areas.
9. Do not weld to the lift truck without disconnecting the pressure sensor.
10. Check the accuracy of the scale on a regular basis to prevent faulty readings.
11. Only trained and authorized personnel are allowed to operate the scale.
12. Always follow the operating, maintenance and repair instructions of this truck and ask the

Push Zero button
Display will read 0 LB

8
Weighing
Bring forks with weight above
reference point
Lower forks with weight slowly to
reference point
Display will show the weight. (plus

Summing weights
Bring forks with weight to reference
height
Display will show the weight
Push the summation button
Display will show blinking 3 times
the total weight and the sequence
number (quantity of weights which
are totalized)
If printer is available, weight of 500
LB will be printed with sequence
number 1.
For second weight (if 250 LB is
totalized)
If printer is available, 250 LB will be
printed with sequence number 2.

10
Read total weight.
Push the summation button
for 3 seconds
Display shows 3 times total
weight and 3x sequence
number.
After 6 seconds display will
return in normal weighing
mode.

11
Reset total weight
Push the summation button
for 3 seconds
Display shows 3 times total
weight and 3x sequence

3 INSTALLATION
How it works
The display unit (1) measures the hydraulic oil pressure with extreme high accurate
oil pressure sensor (2).
Nevertheless, the system has limited accuracy because of friction in the rolls.
The friction in the rolls depend on
1. Condition of the mast.
a. When old, dirt or bad rolling rolls may have a influence
b. When brand new, the first week of use will also create changes. This is
solved because the system is very easy to calibrate.
2. Position of the load. With the load placed to the right or to the left, the friction
changes and less weight is transmitted to the cylinder and measured by the
sensor. Place the load as much as possible as when done during calibration.
3. Mast should be vertical. When more than 1 degree out of level, this becomes
of influence.
4. Speed at which you lower to reference point when done briskly or slowly, may
cause changes. Best results are obtained when lowering slowly to the
reference level.
Specifications
The RCS can be installed on trucks with any capacity.
The RCS works properly with hydraulic pressures up to 5075 psi (350 bar).
The RCS operates on 4 AA batteries for several years.
The sensor is equipped with a BSP1/4" male thread. The sensor is supplied together with an adaptor
to change from BSP1/4" male into NPTF18mm male.

.
It is recommended that the installation of the system is executed by an
official forklift truck dealer.
For the best accuracy the mast, rollers and bearings should be in good
condition:
.
Make sure there is no pressure on hydraulic system before
working on hydraulic system
