INSTALLATION•
7
2 Installation
1. Check that the delivery corresponds with the delivery note. The hoist is delivered fully
assembled.
2. Make sure that the suspension device is approved for minimum 1,5 x maximum lifting capacity
of the hoist. The suspension chosen must be approved for lifting purposes and designed for
a maximum lifting capacity of AT LEAST the weight of the load AND the dead weight of the
hoist.
3. The hoist is designed to be suspended in two track trolleys.
4. Connect the power supply cable to electric supply network (10A fuse).
NOTE! Step 4 must be performed by authorised electrician.
THE HOIST IS NOW READY TO USE AFTER THE PRELIMINARY CHECK HAS BEEN
PERFORMED.

• USER’S GUIDE
3 User’s guide
Operating instructions:
Operating the hoist is accomplished by moving the thumb wheel left (down) or right (up). The
lifting speed is adjusted by means of increasing/decreasing the angle the thumb wheel is moved.
Preliminary check:
Check the function of the upper limit switch by running the hoist upwards until the switch stops
the hoist. This switch is to be considered as an emergency stop switch and it should not be used in
the daily operation. When running downwards the wire will stop feeding out automatically when
the load/hook reaches the oor or if the lower switch is activated.
The hoist is equipped with an electrically operated break that automatically breaks the movement
when the thumb wheel is moved to neutral position. The break function produces a slight clicking
sound, which is normal for this type of break equipment.
NOTE! Never use the hoist if damage has been found. Contact your dealer for repair.

SAFETY INSTRUCTIONS•
9
To ensure maximum personal safety it is essential to avoid all incorrect use:
• Do not allow untrained sta to operate the hoist.
• Do not exceed the hoists maximum lifting capacity.
• Never use the hoist for lifting person/persons.
• Never leave load hanging in the hoist.
• Never move or stand below hanging load.
• Never use the lifting wire as earth lead when welding.
• Never use the hoist to tow goods on the oor.
• Repairs and/or adjustments may only be performed by authorised personnel.
• Always read the manual carefully before using the hoist.
• Make sure that the load is well balanced before lifting.
Caution!
• Neglect in following the safety instructions may cause serious bodily harm.
• The operator must be fully trained in handling the hoist.
• All instructions in this manual must be followed at all times.
• The crane system/suspension unit must be installed by authorised personnel and all safety
regulations must be followed. DO NOT EXCEED maximum lifting capacity. (Dead weight of
hoist+weight of load).
• Maintenance instructions must be followed and only original spare parts may be used.
• The suspension must be thoroughly checked on a regular basis.
• Electrical installations/alterations may only be carried out by authorised electricians.
