Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Close the bleed-type master air valve (F, page 6)
(required in the system).
2.
Relieve pressure
in system using two wrenches
working in opposite directions on the pump outlet
(E) and lubrication line fitting (G) to
slowly loosen
the fitting until it is loose and no more lubricant or
air is leaking out of the fitting (F
. 6).
Air Lock Procedure
The reference letters used in the following instructions
refer to the Typical Installation F
An air lock occurs when a bubble or pocket of air pre
-
vents the normal flow of the lubricant.
If there is an air lock:
1. Refill the reservoir to the full level (page 8).
2. Relieve pressure. See
Pressure Relief Procedure
,
page 10.
3. Disconnect the lubricant supply line (G) from the
pump outlet (E) (F
. 7).
4. Open the bleed-type master air valve (F, page 6).
5. Run the pump a few strokes until grease, free of air,
comes out of the pump outlet (E) (F
. 7).
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop dispensing and before
cleaning, checking, or servicing the equipment.
