VacuEasylift lifters are made for use under a roof protected from wind and rain.
• The lighting in the place of installation must be adequate, during installation and operation.
• The overhead crane system/jib crane must be approved for the rated maximum lifting capacity of
the vacuum lifter.
• During design and installation of the suspending system, it is vital to take into account relevant
standards and regulations, the load bearing capacity of the ceiling and oor structure and the
attachment devices and the relevant basic design information of the suspending system. For
information on suspension (jib crane, crane system etc) see separate manual.
• The overhead crane system must be installed by qualied technicians and all safety and maintenance instructions must be followed.
• Re-tighten all bolts within 1-2 months of installation.
• This vacuum lifter may not be used before the test in Appendix I has been carried out and signed.
• Do not start/test the vacuum pump before installation is complete and the suction foot is >10 cm
from ground!
• Any modications to the product must be carried out by qualied TAWI technicians.
• A mandatory dynamic operational test must be executed before the vacuum lifter may be put
into operation.
• Motion limiters may not be used to limit the horisontal motion of the vacuum lifter. The installation of a motion limiter may cause serious damage to the vacuum lifter. It may also cause involuntary disengagement of parts resulting in parts falling down and the risk of serious body injuries.
• Note the colour code system for safe assembly of lift unit to suction foot /accessory. ONLY
PARTS WITH MATCHING COLOUR CODE MARKING MAY BE ASSEMBLED! Incorrect combinations of lift unit and accessory may cause very serious injuries.
Verify installation
When the installation of the vacuum lifter is carried out, and before the vacuum lifter is put into
operation, it must be submitted to a dynamic operational test at the place of installation. The dynamic
operational test must be carried out by qualied technicians with a load of 1.1 times the maximum load
specied by the manufacturer.
This test shall be carried out for each motion of the vacuum lifter, testing its full function, with repeated
starts and stops throughout the complete working range.
This test shall be considered successful if the vacuum lifter has been found to perform all its functions
and if the examination subsequent to the test reveals no damage to mechanisms or structural
components, and no connection has been loosened or been damaged.

4 Service & maintenance
This chapter provides information about service and maintenance of the lifters. The chapter is divided
into sections based on who is to perform the inspections and how often the inspections are to be
carried out. Weekly by the operator, quarterly by inhouse maintenance or yearly by TAWI authorised
service technician.
For technical service, maintenance or repairs contact your TAWI representative or [email protected].
TAWI must authorise all modications to this product. TAWI assumes no responsibility for unauthorised
modications and guarantees will automatically become invalid if unauthorised modications have
been made.
• Service must be carried out on a yearly basis.
• If any damage/wear is detected on the lifter, this must immediately be reported to TAWI or authorised TAWI representative. The lifter must be taken out of commission and not be used until
the damage has been repaired.
• All service must be carried out with the power supply disconnected.
• In order to deal with the vacuum pump cables, a good knowledge of electricity and TAWI electrical schedules of the lifters is required.
• The service/maintenance sta carrying out repairs must have adequate experience and knowledge for this kind of work. If there are any doubts regarding method, material etc., please contact the manufacturer.
• The use of non-original spare parts invalidates the warranty and can cause risk of personal injury
and damage to the unit.
• Keep clean. Never spray or pour water onto any part of the vacuum pump or electrical cables.
Page 20

Inspections
The following inspections are to be carried out.
Quarterly inspections by inhouse maintenance
1. Double check (carry out) all inspections mentioned in Weekly inspections by operator.
2. Check the lift and crane system or jib rig for signs of damage/wear and that bolts and pins are
tightened and in place.
Yearly inspections by TAWI authorised service technician
1. Perform the actions described in the yearly Service-/Inspection report provided by TAWI.
2. Update the Inspection record in Appendix II.
Weekly inspections by operator
1. If yearly service has been carried out, make sure that the service inspection date is valid.
2. Check all bolts and nuts for damage or wear.
3. The top swivel joint includes a safety valve. The valve automatically closes if the power fails and
the load sinks to the oor under control. Check the operation of the safety valve by lifting a load
approximately 1 m., close the operating handle fully, and then stop the vacuum pump. The load
should be equivalent to the rated max lifting capacity and of a non-porous material (for example,
a steel plate). A controlled sinking motion is correct – anything else: do not use the lift and contact your vacuum lifter dealer immediately.
4. Check all connecting components (clamps between lift tube and suction head, clamps between
lift tube and top swivel, clip and pin in crane system trolley eyelet, air tube clamps, bolts for suction foot).
5. Clean the air lters (lter unit and suction foot), more often if the working environment demands
it.
6. Check the lift and air tubes for signs of damage or wear. A damaged lift or air tube must be re-
placed immediately.
7. Check that the max lifting capacity, warning and operating signs are visible.
8. Make sure the lift runs smoothly in the crane system or jib rig.
9. Make sure that the operating valve is functioning properly.
10. Check that the vacuum lifter achieves maximum lifting capacity. The designated load should be
easily held by and lifted with the vacuum lifter. Lifting capacity is reduced if a vacuum leak occurs. See trouble shooting for more info.
