engine off, turn the key on, and move the hydraulic control lever through all movements several times
to relieve residual pressure in the system.
Failure to comply could result in death or serious injury.

Replace the hydraulic oil filter when the hour meter registers 100 hours for a new machine during the initial run-in
period. The filter should be changed every 2000 hours thereafter or more frequently when operating conditions are
severe.
Prior operation:
Keep all unauthorized personnel clear of the area. Park the machine on level ground, in neutral with the parking
brake applied, and the attachment lowered to the ground. Make sure that all residual pressure is relieved from circuits
before beginning maintenance. Install the transport service link to prevent unexpected articulation.

switch.
3. Make sure the accumulators on the machine are com-
pletely discharged.
