Safety Precautions To Be Taken When Working
With Hydraulic Systems
As with all hydraulic systems, it may be necessary to periodically check and adjust the pressure relief
settings. It may be that a major hydraulic component has been changed, the unit is not performing in
terms of payload, or the unit has recently been put into service and the system requires adjustment
following a run-in period.
Warning!
If a hydraulic component has to be changed or a repair to the hydraulic system is needed,
always apply the lockout/tagout procedure first (see Locking Out and Tagging Out the
Vehicle on page 21). Failure to do so may result in severe injury or even death. Be sure to
fully read and understand this chapter before doing any repair.
Please take note of the following:
 Mechanics must have previous hydraulic knowledge as serious injury or death can result from
following improper procedures.
 Human skin can be easily penetrated by high pressure oil (2000 PSI and above). Failure to take
appropriate safety precautions may result in serious injury or death.
 There are extreme overhead dangers if equipment is not properly supported when servicing
sections on the hydraulic system.
