Safety instructions for installing hydraulic components

The  following  safety  procedures  must  be  followed  when  handling  hydraulic  components.  Contact  your
nearest Avant dealer or service point if you have any additional questions or if you need installation services.
It is recommended to leave the installation of hydraulic components to professional service technicians.

Before  handling  hydraulic  components,  make  sure

that the hydraulic system of the attachment and  the

loader  are  completely  depressurized.  Never  handle

pressurized  fittings.  See  instructions  on  page  14  to

release  the  residual  pressure.  Do  not  hold  your

hand  near  a  fitting  when  tightening  or  opening  it.

High pressure fluid ejection may penetrate skin  and

cause  serious  injuries.  Seek  medical  attention

immediately  in  case  hydraulic  fluid  is  injected  into

the skin.

Make  sure  the  attachment  is  securely  lowered  on

the ground. Any part of the attachment must  not  be

supported  only  by  the  hydraulic  pressure  or

hydraulic cylinders. Do not loosen any fitting as long

as  any  part  of  the  attachment  may  move.  Use

additional  supports  as  necessary.  Lower  the

attachment  securely  on  the  ground,  shut  down  the

loader  engine  and  lower  the  grapple  on  ground  or

additional  supports.  Depressurize  the  hydraulic

systems completely.

Ensure that the loader boom or any part of the attachment will not move and cause a crushing hazard:

1.  Lower the boom to its lowest position
2.  Lower the attachment firmly on the ground
3.  Lower  the  grapple  or  otherwise  block  the  movements  of  the  grapple.  Use  additional  supports  or

lifting equipment as needed.

4.  Shut down the loader engine.
5.  Move the auxiliary hydraulics control lever to its extreme positions several times to release residual

pressure.
