Insert the wedge between the block and the cable.
Pull the cable to tighten all components. Now lock the cable with
a U-clamp so that the fl at part remains in contact with the lifting
section of the cable.
Fit the hook to the block and tighten the bolt and locknut.
Check that the UP limit switch operates when the counterweight
touches the lever.
Run the load test described in paragraph 5 and note down in
the Maintenance Log#1 the fact that the cable has been changed.

7.1.2 MAINTENANCE SCHEDULE

- Visually check the condition of the cable every day
and whenever it is subjected to abnormal strain (twisting,
bending, kinks or abrasion).
Replace the cable when defective (Fig. 13).
Inspect the entire cable carefully every two months and in particular
the ends; note the results in the Maintenance Log#1 which must
be kept by the site foreman.
Replace the cable at least once a year.
7.2 ADJUSTING THE MOTOR BRAKE (Fig. 6)
The braking system on the Pull Up 450 does not need power
(current) to engage.
The system is designed so that if there is a loss of power while the
hoist is operating, the braking system will engage automatically
and stop the load from going down.
If its braking power is reduced a qualifi ed technician must check
the device and adjust it.
- Warning!! Before servicing the brake make sure that
the winch is not loaded and that the brake's power supply
is disconnected.
Remove fan cover (A), and adjust
the air gap "d" between magnet (B)
and brake disk (C) by means of a
feeler gauge.
The gap (d) must be 1/64 inch
(0.4 mm).
Measurement should be taken at
three points in order to check that
the disc is perfectly parallel to the
magnet. Slide the feeler gauge
lightly backwards and forwards.
If the air gap is too wide, reduce
it by tightening nut "D" with a
ring spanner. Check distance "d"
several times. If the air gap is too
small, increase it by unscrewing
the nut "D".
Once the air gap has been cor-
rectly adjusted, refi t cover "A".
To check braking power, after
carrying out the adjustment, repeatedly test braking action under
full load conditions.

7.3 GEARBOX LUBRICATION

- The gearbox must not develop grease leaks. Leaks may indicate
damage to the aluminium casing. In this case, reseal or replace
the casing.
- The grease should be changed every 2000 hours.
- Used grease is classed as special waste. As such,
it must be disposed of in accordance with the established
legislation.
7.4 ELECTRICAL PANEL AND PENDANT CONTROL
Check the condition of the pendant control case, the cables and
the electric panels, if damaged, they should be replaced with the
correct IMER spare part.

8. DISMANTLING

Take any load off the lifting hook.
Wind the cable completely onto the drum. Disconnect the ma-
chine from the mains. Disconnect the pendant control from the
electrical panel.
Remove the hoist from the scaffold mount trestle.
9 TRANSPORTIATION AND STORAGE
Do not leave the installed hoist unattended without having fi rst
wound the cable completely onto the drum and disconnected the
electrical power supply.
When storing the machine for a long period of time, protect it
from the weather.
- During transport, protect the machine from blows and crushing
to avoid compromising its functionality and mechanical strength.

11. WHAT TO DO IF THE HOIST QUITS WORKING WHILE A
LOAD IS BEING LIFTED
- If possible remove the load from the nearest fl oor level, then
dismantle the hoist and service it.
- If this is not possible, use another lifting machine from higher
up and suspend the faulty hoist both at the load and at the hoist
attachment point. The replacement hoist must be capable of
lowering both the suspended load and malfunctioning hoist, i.e.,
add the weight of both pieces together to determine the capacity
that will be required for the rescue hoist.
Remove the split pin and lift the faulty hoist slowly off its fi tting,
then lower the entire load to the ground.
- DO NOT adjust the motor brake with the load suspended as it
would be uncontrollable.
- DO NOT try to service the machine with the load suspended.
