personnel. Take all necessary safety precautions.
- Warning! The winch must be tested before use.
Before testing the hoist make sure that it has been correctly installed.
1) Lower the unloaded rope to the lower loading position, and check
that at the end of its travel three turns of rope remain on the drum.
2)
No-load test.

Test the up, down and emergency stop buttons, UP limit switch
operation, correct rope winding onto the drum and motor brake
operation.
3)
Load test.
Load the hoist with its maximum admissible load. Run

the motor brake.
After the test, check the support structure for failure and slippage and
recheck the drum level (use a level as in Fig. 1).

fully raised position (9).
It is however good practice to stop the hoist before the safety
device activates by releasing the UP button.
When the rope is completely unwound, the operator standing near
the machine must check that the rope does not wind onto the drum
in the wrong direction.

installation check and signature (Table 2) along with any other
comments.
The test procedure described above, complete with
no-load (2) and load (3) tests, must be performed every time
the machine is installed.
6. SAFETY WARNINGS AND OPERATING PRECAUTIONS
- 1) Do not lift weights exceeding the hoist’s capacity.
- 2) Do not allow anyone to stand underneath suspended
loads.
- 3) Do not attempt to raise loads that are anchored to
the ground (e.g. buried posts, plinths, etc.).
- 4) Make sure that the load is correctly attached to the

4.1, 6).
- 5) If the load requires the attachment of accessories
EHOWVURSHVVOLQJVHWFWKHVHPXVWEHRIDFHUWL¿HGDQG
approved type. The maximum capacity must be reduced by
the weight of these accessories.
- 6) Make sure that no part of the load detaches while it
is being lifted.

ground before releasing it from the hook.
- 8) Do not release a suspended load using accessories
that permit instantaneous release or by cutting the sling
since this can give rise to an elastic counter-reaction of the
entire structure.
- 9) Keep your hands and body well clear of the drum
during operation to avoid them getting caught in the winding
rope; this can result in serious injury.
- 10) Keep your hands and body well clear of the
counterweight during lifting to prevent them being crushed
against the stop lever.
- 11) Do not use the machine in adverse weather
conditions (wind or storms) as the load is not guided.
Maximum wind speed must not exceed 12.5 m/s.
- 12) The control position and lighting conditions must
permit a good view of the load throughout its travel.
- 13) Check that all guards are in place.
- 14) During operation check that the rope winds on
correctly, one turn at a time, without slack or overlaps, as
this can damage it. If it fails to do so, unwind it and rewind it
correctly under tension.
- 15) Make sure that the lifting run is free from obstacles
and make sure that no one can lean out from intermediate
ÀRRUV
- 16) Cordon off the ground loading area to prevent
anyone from entering during lifting.
- 17) Keep children away from the hoist.
- 18) Do not allow unauthorised persons access to the
hoist while it is not being used.
- 19) The hoist must not be used for pulling loads
obliquely (more than 5° away from vertical).
- 20) Do not rotate the winch on its pivots by pulling the
pendant; move the frame itself by hand;
- 21) Do not leave a suspended load unattended. Raise
or lower it and unload it.
- 22) When a load is to be raised or lowered, this must
be done in such a way as to minimise dangerous sideways
and vertical movements.
- 23) Before leaving the hoist unattended, remove the
load, completely wind the rope onto the drum and disconnect
its power plug.
- 24) Do not allow the load to spin while it is being raised
or lowered as this could cause the rope to break.
- 25) Protect the winch against the rain.
When operation is resumed after a lengthy period of disuse the entire
machine must be tested under no-load conditions before starting, as
described above (point 2, Chapter 5).
7. TESTING AND MAINTENANCE
Warning!! Only carry out maintenance with the machine
switched off, unloaded and disconnected from the mains.

Service.
- Use only IMER original spare parts.
- Check the motor brake every 6/7 days.
- Ensure that the notices and inscriptions on the
machine are prominently displayed and legible.
- Keep the machine clean of dirt.
- Check the operation of the UP position limit switch
at the start of each work shift.
- Check the electrical cable at the start of every work
cycle for accidental damage.
