ESSENTIAL SAFFETY REQUIREMENTS 

WRONG 

 

Place  the  equipment  on  a  flat  and  solid  area.  Define  stable  zones  for 
applying  the  load  and  safety  zones  for  operators,  separating  them 
through  the  use  of  hoses  of  enough  length.  Use  our  base  plates  if 
necessary.

 

 

 

Secure the load mechanically once the movement has been completed 
and avoid operating underneath them.

 

 

 

Center the load in the cylinder. Use the entire cylinder’s useful support 
surface,  both  on  the  head  and  on  the  base.  Use  tilting  saddles  under 
side loads. 

 

 

Do not expose the equipment to intense heat sources (welding), nor to 
temperatures above 65°C. 

 

 

Remove  loads  before  carrying  out  maintenance  operations  and  always 
work in clean, well-lit areas.  

 

 

Include control elements (pressure gauges) in the installation in order to 
enable the operator to monitor the pressure in the system and ensure 
that the equipment’s nominal capacity is never exceeded. Be prepared 
to use safety valves and accessories if safety criteria demand it. 

 

 

The  cylinder  controls  should  be  activated  manually,  as  should  the 
connections between elements equipped with couplers.

 

 

 

Once  you  have  finished  using  the  device,  check  that  it  has  not  been 
damaged, clean it and protect it ready for storage. If there are worn or 
damaged pieces, replace them with new ones.

 

 

 

Clean  the  couplers  before  connecting  and  ensure  the  connections  are 
perfect  (first  insert  as  far  as  the  coupler  will  go  and  then  screw  it  by 
hand).  A  bad  connection  may  result  in  improper  functioning  and  may 
even generate a safety hazard.

 

 

 

Install  the  device  in  such  a  way  as  to  ensure  that  the  hoses  are  not 
subjected  to  sharp  or  forced  bends  or  thrust  actions  that  may  cause 
them  to  break.  Never  disconnect  the  hoses  when  the  system  is 
pressurized.
