Hydraulic system, releasing pressure
WARNING
Risk of high pressure injection.
Residual pressure in the hydraulic system could
lead to oil under high pressure jetting out and cause
serious injury, even if the engine has not been
running for some time.
Always release the pressure before any kind of
service of the hydraulic system is carried out.
Use the greatest caution when working on the
hydraulic system. Remove system pressure and
tank pressure:
1 Place attachment on the ground and shut down
engine.
2 After engine is shut down, turn ignition switch to
running position (Do not start engine).
3 Keep the control lockout lever up (unlocked
position) and move all control levers and pedals
to release main system pressure from all lines.
4 Turn ignition switch to OFF position, remove the
key and tag the machine to indicate that the unit
is under service.
5 Lower the control lockout lever (locked position).
6 Press the pressure relief valve located on the
hydraulic tank breather valve to release tank
pressure.
