Hydraulic Control Valves
Remove And Install Hydraulic
Control Valves
Hydraulic oil under pressure can remain in the
hydraulic system after the engine and pump have
been stopped. Personal injury can result if the
pressure is not released before any work is done
to the hydraulic system. To prevent possible
personal injury, turn the engine off and move the
control levers to make sure the hydraulic pressure
is released before any fitting, plug, hose or
component is loosened, tightened, removed or
adjusted. Always move the lift truck to a clean and
level location away from the travel of other
machines.
NOTE :
For purposes of reassembly, put
identification marks on all lines, tubes and hoses
before any disconnections are made.
