Lifting 

The 

hydraulic 

power 

unit 

weighs 

approximately  30  kg.    If  it  is  necessary  to 
use a lifting harness, under no circumstance 
place 

it 

around 

valves, 

gauges 

or 

accumulators  (see  correct  lifting  process, 
below). 

If  not  mounted  in  cabinet  the  hydraulic 
power  unit  may  be  lifted  in  the  motor 

– see 

figure   1.3 

 

CAUTION 

Do  not  lift  the  hydraulic  power  unit  in  the 
valves etc. 

– see figure 1.4 

If  the  hydraulic  power  unit  is  mounted  in  a 
cabinet the entire assembly may be lifted by 
using  the  lifting  point  in  the  supporting 
frame. 

1.7 

Storage 

Hydraulic  power  units  must  be  stored 
indoors  in  a  clean,  dry  area.    They  must  be 
stored  in

 

such  a  way  that  they  cannot  be 

damaged by passing or falling objects.  
For  indoor  storage  for  up  to  3  months  the 
hydraulic  power  units  do  not  need  any 
surface  treatment.  For  longer  periods  they 
should  be  covered  with  a  plastic  or  canvas 
cover to protect against dirt. 

1.8 

How to order spare parts 

When  ordering  spare  parts  please  refer  to 
the  specific  item  number  in  the  parts  list 

– 

see appendices.
