(1) Auto-fill shutoff valve
(2) Grease reservoir
(3) Pressure gauge
(4) Pressure relief knob
(5) CouplingGrease reservoir (2) for the automatic lubrication system is located on the rear of the machine.Procedure for Refilling Reservoir
Location for Ground Level Fill
Coupling (5) on the filler assembly is located on the left-hand ripper cylinder.Filling the Reservoir
Ensure that the hose is full of grease in order to prevent air from being pumped into the reservoir.
Pull pressure relief knob (4) out and relieve line pressure to auto-fill shutoff valve (1). The auto-fill shutoff pin will lower, indicating it has been reset.
Clean the coupling for filling and the coupling of the hose for filling.
Attach the hose for filling to the coupling for refilling. Refill the reservoir to the maximum level. The air is allowed to purge off during the filling of the reservoir.
The filling process is complete when the following conditions are met:
When the auto-fill shutoff valve (1) pin pops up.
When the pressure gauge (3) rises to the fill pump's set pressure.
Disconnect the hose for filling and clean both couplings.Location for Lubricating

(1) In order to use a non-Caterpillar lubricant, the supplier must certify that the lubricant is compatible with Cat grease. Otherwise, fully flush each pin joint with the new lubricant in order to remove the Caterpillar lubricant. Failure to meet this requirement may lead to failure of a pin joint due to premature breakdown of the lubricant.
