Accumulator
This system contains high pressure gas. Failure to follow the instructions and warnings could cause an explosion,
resulting in possible injury or death. Do not expose to fire. Do not weld. Do not drill. Do not remove any hydraulic
system lines, taps or parts until pressure has been relieved. Relieve pressure before discharging. See Operation and
Maintenance Manual "Accumulator - Relieving Charge". See Operation and Maintenance Manual "Accumulator" for
charging and discharging. See your Dealer for tools and detailed information.
Accumulator must be charged with dry nitrogen (N
2
) gas by qualified personnel only. The accumulator must be at the same
temperature as the surrounding air before being checked or charged. Charge the accumulator depending on the ambient air
temperature according to the table below. Access the accumulator to charge from the rear of the tractor, above the tow-
winch drive.
