Setting of the switching points
set screw 1 "switching point 1 (lifting)"
The switching point can be set at any desired point
between upper and lower hook path limit. In order
to adjust move the load hook to the desired
position, which is possible by turning the set screw
1 to the left side. Afterwards turn the set screw 1 as
far to the right side until the switching contact
switches audible. 114 turns of the set screw mean
360° at the cam.
Drive two times into the desired hook position (1
creep speed, 2 main speed) and check the
switching point, adjust if necessary. The load
attaching device may not touch the housing and
thereby activate the slipping clutch.
set screw 2 "switching point 2 (lowering)"
The switching point can be set at any desired
point between upper and lower hook path limit. In
order to adjust move the load hook to the desired
position, which is possible by turning the set
screw 2 to the right side. Afterwards turn the set
screw 2 as far to the left side until the switching
contact switches audible. 114 turns of the set
screw mean 360° at the cam.
Drive two times into the desired hook position (1
creep speed, 2 main speed) and check the
switching point, adjust if necessary. The chain
attaching part may not touch the housing and
thereby activate the slipping clutch.

Safety check
Before putting into service initially or when putting back into service, it must be checked whether:
All fastening screws (if existent), socket pins, flap socket and safety devices are tightened and secured.
The oil levels in the gear boxes are sufficient.
All movements of the load comply with the symbols on the control switch.
The chains are correctly placed, oiled and in good condition.

Functional test
11.1
Checks before the initial start-up
Lifting gear
Load chains must not be twisted.
Lubricate the load chain with gear oil or suitable chain lubricant before first loading.
Trolley drive
The open-lying teeth of the trolley drive must be lubricated.
Hand gear for hand geared trolley
Ensure correct fit of the hand chain, it must not be twisted and must hang freely.
11.2
Functional test
Lifting gear
Check lifting and lowering functions, initially without a load. The buttons of the control switch are marked with
the symbols for lifting and lowering. The movement direction of the load (lifting or lowering) must correspond
with the push buttons (lifting or lowering). This is the factory setting.
If the device lower
s when the “lift” button is operated and lifts when the “lower” button is operated, the two
phases of the net connection must be swapped.
The function of the end switch is to be checked initially by operating the end switch by hand. Then carefully
move to the end position. If required, adjust end switch.
Then check the brake function under load. After releasing the buttons of the control switch, the load must be
securely held.
Trolleys
Carefully move the trolley to the end positions and check the positions of the end stops.
