6.0 Long live the Rotator
6.3 The hydraulic pump and the gear motor
The hydraulic pump has a S3 “periodic intermittent duty” of 10%. This means that
the pump in total is allowed to operate 1 minute for a period of 10 minutes. If the
pump operates more than 10%, the motor will be damaged due to superheating.
Bleeding the hydraulic system
With a load of 50-100 kg, the forks must be raised and lowered to top and bottom
position 2-3 times.
Gear motor of Rotator
The gear motor has a ”short time under constant load” of 10 minutes
(S2=10 minutes). This means that the motor is allowed to operate with the
maximum load for 10 minutes. Hereafter it has to be cooled down to normal
temperature.
NOTE!
The motor will be damaged by superheating, if it operates for a longer time
or if it is not cooled down.
6.4 Fork adjustment
Two of the rollers on the fork bracket are
mounted on eccentric pins, so that they
can be adjusted. The adjustable rollers
are at the top.
1. Loosen screw (pos. 91)
(key width 5 mm).
2. Eccentric pins (pos. 56)
(key width 8 mm) can now be turned
to give the necessary fork adjustment.
3. Adjustment must be made on both
sides to ensure uniform loading of the
rollers.
