2.3 Hydraulic Jack Specific Safety Precautions 

Failure to observe and obey the following safety precautions could result 
in property damage, serious personal injury or death;    

 

DO NOT

 work under or near a load supported only by hydraulic means. A hydraulic jack, when used 

as a lifting  device, should not be  used  as a load-holding device. Once  lifted, all loads should be 
supported using rigid mechanical structures. 

 

 

ALWAYS 

raise the piston to the load. 

DO NOT

 drop loads onto the jack. 

 

NEVER

 exceed the maximum rated capacity of any hydraulic jack and 

DO NOT

 attempt to lift a load 

greater than the jack’s stated maximum capacity.  

  Overloading hydraulic jacks can result in component failure and possible serious personal injury. 

 

ALWAYS

 place hydraulic jacks on a flat, even surface that supports the entire base plug (6) and 

can support the load to be applied. 

  Where applicable, use an additional support base to assist in supporting the load to be lifted. 

  Avoid lifting loads that are not central to the lifting piston. Avoid offset loading as this can damage 

the cylinder bores and piston rods, and also lead to unstable load lifting. 

 

 

DO NOT 

weld any items to the jack or modify it in any way from its delivered condition. Your warranty 

may be invalidated, and it could lead to serious personal injury. 

 

 

Failure to observe and obey the following safety precautions could result 
in  property  damage,  equipment  damage  or  minor/moderate  personal 
injury; 

  To protect your warranty, only use hydraulic oil grades as specified in the oil table in 

Section 8.1

.

 

  Make  sure  there  is  sufficient  spare  lifting  capacity  and  stroke  when  selecting  Jack/s  for  any 

application.

 

 

Ensure hydraulic jacks are used only under environmental conditions that are suitable for their use. 
The  jacks  proper  functioning  cannot  be  guaranteed  under  adverse  conditions,  and  a  shortened 
product lifespan can result.
