er does no

t lift

Vacuum pump not started

Check function of vacuum pump. See 

Install vacuum 

pump on page 4

.

Load too heavy

Reduce load. It must not exceed the lifting capacity of 

the lift.

Air leakage

Check connections, air and lift tube for damage or 

wear. Tighten clamps and, if necessary, change air or 
lift tube (see 

Shorten or change lift tube on page 

8).

 Check filter unit for leakage.

Dirty vacuum pump filter

Clean filter inset, see

.

Vacuum pump installed in the wrong 

direction

Check the direction of rotation of the vacuum pump. Is 

air blowing from the silencer? If not, change the phas-

es over. This must be carried out by a qualified electri-
cian, see 

Install vacuum pump on page 4

.

Suction foot installed incorrectly

Remove suction foot and clean the foot filter. Refit 
suction foot, see 

Install suction foot and touch bolt 

on page 10

.  Do not overtighten the fixing bolts. 

Problems can occur because the bolts are undertight-
