7. Operation
7.1 Information for operation
1. Remove the adhesive tape from the drum (3)
before using the hoist for the first time.
2. The cable hoist must be operated in ambient
temperatures of between 0°C and 40°C with a
relative humidity of less than 85%. Height above
sea level: max. 1,000 m.
3. The temperature for transport and storage may
be between -25°C and 55°C. The maximum
temperature must not exceed 70°C.
4. The user should lift the load off the ground at the
slowest possible speed. The cable should be taut
when the load is raised.
5. The motor (14) for the cable hoist is fitted with a
thermostat switch. Whilst the cable hoist is
operating, the motor (14) may therefore stop. It
will restart automatically when it has cooled
down.
6. The electric cable hoist is not fitted with a rated
power limiter. You should therefore not repeat
attempts to lift a load if the overload trip is
limiting the hoistʼs operation. In this case the load
exceeds the rated capacity of the cable hoist.
7. Do not leave any suspended loads unsupervised
without first taking the appropriate safety
precautions.
8. Do not use the lever (4/5) as a routine stopping
device. It should only be used to stop the
machine in an emergency.
9. Before you start, ensure that the steel cable (6)
is correctly wound around the drum (3) and that
the spacing between the windings is smaller than
the steel cable (Fig. 3)
10. Ensure that the load is correctly secured to the
hook (8) or, if you are using the block and tackle,
the additional hook (16) and always maintain a
safe distance from the load and the steel cable
(6).
7.2 Operation (Fig. 1)
Check whether the Emergency Stop switch (9) is
pressed. Turn the red stop switch clockwise to
release it.
Press the pushbutton ▲ (10) to raise the load.
Press the pushbutton ▼ (10) to lower the load.
Automatic stop mechanism lever (5): When the
maximum lifting height has been reached, the
cut-out weight (7) presses the lever (5) upwards.
This trips a limit switch after which the load
cannot be raised any further.
Lever for maximum cable length (4): When the
load has reached its lowest possible position, a
limit switch is tripped which makes it impossible
10
to lower the load any further. This limit switch
also prevents the cable hoist operating in the
wrong direction (hook moving in the opposite
direction to the arrow shown on the control
switch).
The cable hoist will stop if the Emergency Stop
switch (9) is pressed.
In an emergency, immediately press the
Emergency Stop switch (9) to stop the cable
hoist. The cable hoist cannot be operated if the
Emergency Stop switch has been pressed.

8. Cleaning and maintenance

Danger!
Always pull out the mains power plug before starting
any cleaning work.
8.1 Cleaning
Keep all safety devices, air vents and the motor
n
housing free of dirt and dust as far as possible.
Wipe the equipment with a clean cloth or blow it
with compressed air at low pressure.
We recommend that you clean the device
n
immediately each time you have finished using it.
Clean the equipment regularly with a moist cloth
n
and some soft soap. Do not use cleaning agents
or solvents; these could attack the plastic parts of
the equipment. Ensure that no water can seep
into the device.
8.2 Servicing
Important. Always ensure that the machine is not
connected to the mains supply before you start
any servicing work.
In the following: One cycle means one raising
and lowering movement of a load. Periodic
inspection means an inspection after 100 cycles.
Test periodically that the limit switches on the
cable hoist are in correct working order. Conduct
this test as follows: When the cable has reached
the maximum height, the lever on the automatic
stopping mechanism (5) will be actuated. The
motor (14) must then stop. (Test without a load).
When the steel cable (6) has been unwound as
far as possible, the lever for the maximum cable
length (4) will be actuated. The motor (14) must
then stop.
Inspect the mains cable (12) and the control
cable (13) periodically.
The steel cable (6) and return roller (15) must be
greased every 200 cycles.
A check must be made every 30 cycles, as
shown in Fig. 4, to find whether the entire steel
cable (6) is in good condition. If it is damaged, it
