Power off the machine. Close the primary air valve. This stops the air supply to the machine.
Pull the ring on the pressure relief valve on the air and lubrication manifold. This releases the air pressure from the system.
If the machine has a metal reservoir, go to Step 3.
Place shop towels under the reservoir to catch any grease that may fall.
If the machine has a plastic reservoir, use the supplied wrench to loosen and remove the grease reservoir.
Inspect the reservoir for cracks or damage. Replace the reservoir if it is damaged, chipped, or cracked.
