NOTE: When using this lifting tower in public places or industrial areas, a series of safety instructions have to be followed that this manual can only give in part. The user must therefore inform himself/herself on the current governmental safety instructions and take them into consideration when planning the installation.

PRE-OPERATION INSPECTION

CAUTION! A pre-operation inspection must be carried out before every use of the tower. Check the tower for damage, improperly installed or missing parts and unauthorised modifications using the list below.
If damages or malfunctions are found in either the pre-operation inspection or the function test the tower should be removed from service and repaired by an authorised technician.

Check the following components of the lifting tower:

Winch
Base and legs
Stabiliser legs and especially levelling jacks
Telescopic sections
Cable (kinks, frays or deformations)
Safety bolts and locking bolts
Spirit level
Ensure all labels are in place and legible

Check the whole machine for:

Dents and damage
Corrosion or rust
Cracks in welding

OPERATING INSTRUCTIONS

WARNING! Always use logic and common sense when using the lifter. This is a complex product designed for professional use and should not be operated by amateurs. Ensure all personnel are correctly trained andinstructed on the content of the manual and the dangers related with operating the lifter.
ALWAYS follow the set-up, working area and tower use safety instructions in this manual.

SET-UP

Position de ELC tower at the desired work site.
Remove the stabiliser legs from the storage sockets. To do this, loosen the knobs that keep them in position.
Insert the stabiliser legs into the base sockets. Secure them with the locking bolts.
Level the tower by adjusting the levelling jacks of the stabiliser legs and using the spirit level located on the mast as a reference.
Once completely levelled, the tower is ready to use.

FUNCTION TEST

Install your chosen adaptor on the tower and secure it. Place a load on the adaptor.
Raise and lower the tower to check the following functions.
Check that the winch is working correctly:
It must operate smoothly and free of hesitation, binding or strange noises.
All components must be present.
And above all it, must brake perfectly.
Ensure that the cable is not worn, has no kinks, frays or serious deformations.
And make sure the telescopic profiles raise and lower smoothly. They shouldn’t be either tight together nor too loose (with a big gap between them). They should be close-fitting.

RAISING THE LOAD
Install your chosen adaptor on the tower and secure it. Place the working load on the adaptor.

WARNING!

The load must be correctly positioned, centred and secured.
Ensure that the load does not exceed the rated load capacity recommended by the manufacturer.

IMPORTANT: When more than one tower is used to lift a structure:

The load should be secured with sufficient slack to compensate the little differences in height between the towers that may occur while raising the tower.
Synchronize the raising as much as possible.
There must be one person raising each tower.
The structure must be levelled (the height difference must be minimal).

Before starting, make sure all safety bolt knobs are in the position with the arrow pointing to the left.

Turn the safety bolt blocking the upper section to the position with the arrow pointing to the right and loosen the knob.
Turn the winch handle lifting this telescopic section, which will automatically block when it reaches the top. IMPORTANT: Do not pull and hold the safety bolt during thelifting process.
Tighten the knob of the raised telescopic again to remove any possible looseness.
Repeat these steps to raise the remaining telescopic sections until the tower is at the desired height. You should hear the safety bolt clicking into each safety hole as the telescopic masts are extended.

IMPORTANT
Stop turning the winch handle when you notice that the movement becomes stiff. This indicates that the mast has reached its maximum height. VERY DANGEROUS: Forcing the winch at this point could cause serious internal damage to the tower.

BLOCKING THE LOAD

Winch: When you let go of the winch handle the automatic brake will hold the load in place.
Safety bolts: Operate the winch until the safety bolt goes into one of the holes on the mast section, this way the safety bolt blocks the load.

LOWERING THE LOAD
To lower the load, follow the steps in the previous section in reverse.

Turn the safety bolt of the bottom telescopic section to the position with the arrow pointing to the right and loosen the knob.
Pull and hold the safety bolt in this position and turn the winch handle lowering the telescopic section.
VERY IMPORTANT: It is necessary to pull and hold the safety bolt while you lower the load. In the unlikely event of cable breakage, the safety bolt would spring into action by letting go of it and would block the load in place.
Once the telescopic is fully lowered, turn the safety bolt knob to the position with the arrow pointing to the left and tighten the knob again.
Repeat this with each telescopic section until the lift is totally lowered.

IMPORTANT: If the safety bolt becomes blocked due to the weight of the load, the crank handle must be turned slightly raising the load. Once this is done the bolt will be unblocked and you can continue to lower the load.

AFTER EACH USE

Remove the adaptor.
Make sure the safety bolts are blocked (with the arrow pointing to the left).
Make sure the knobs on the telescopic sections are tightened.
Pull out the stabiliser legs and place them vertically on their storage sockets.
Tighten the knobs to secure the legs in the stowed position.
Select a safe storage location making sure it is on a firm and level surface and protected from the elements.

TRANSPORT

The tower must be completely folded and blocked by the safety bolts.
The transport vehicle must be parked on a level surface.
The vehicle must be stationary to prevent it from moving whilst loading the tower.
Make sure the vehicle capacity, the loading space and chains or straps used are sufficient to withstand the weight of the lifting tower.
The tower must be secured to the vehicle with straps or slings of adequate load capacity to prevent anymovement.
Use proper lifting techniques to load the tower onto the vehicle.

MAINTENANCE

Carry out a thorough inspection of the telescopic lifting tower to ensure there are no missing components and that there are no broken or damaged parts.
Check that the wheels turn smoothly and are not damaged or dented.
Inspect the legs and telescopic sections to ensure they are in good condition.
Make sure that the spirit level and the levelling jacks are not damaged and function correctly. Grease the levelling jacks periodically.
Test the Automatic Safety Blocking System (ASB System). Ensure that the safety bolts go in and out of the blocking holes correctly and smoothly.
Check that the winch cable isn’t frayed, bent or worn.
Make sure the winch functions correctly and doesn’t show any signs of damage or deformations.
Raise telescopic sections to verify that they slide smoothly.
Make sure the telescopic sections and the winch cable are free of dust and rust and grease them periodically, depending on the frequency the lifter is used).

VERY IMPORTANT: Do not grease, lubricate or tamper with the winch. Consult with a GUIL technician.

A regular technical inspection of the lifting tower must be carried out (depending on the regulations in your country and the frequency of use of the tower) by a GUIL authorised technician, to establish the condition of all its parts.
Your tower is made with high quality long-lasting components. Do not replace parts of the tower that are critical to stability or structure with items of different strength or specification. In the event of having to change acomponent it is important that it is replaced with an original spare part. GUIL will not take responsibility for any direct or indirect consequence due to incorrect use, carelessness or bad maintenance. The guarantee will be invalid if non-original components are used or if any modifications are made to the tower.
