Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1.
Close the
bleed-type master air valve (F)
(required
in the system).
2.
Close the
shut-off valve (V)
on the
oil input sup-
ply pump/system (DD)

Relieve pressure
in system using two wrenches
working in opposite directions on the

(E)
and l
ubrication line fitting (G)
to
slowly
loosen
the fitting until it is loose and no more lubri-
cant or air is leaking out of the fitting (F

Air Lock Procedure
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, first:
•
Check that
input supply oil line (CC)
is connected
and that the oil flow is continuous to
reservoir (K)
.
•
Loosen the
cock valve (BB)
from the
pump reser-
voir cover (L)
to bleed out the air.
If the air lock persists:
1.
Relieve pressure. See
Pressure Relief Procedure
,
page 9.
2.
Disconnect the
lubricant supply line (G)
from the
pump outlet (E)
. 8).
3.
Open the bleed-type master air valve (F, page 4).
4.
Open the
shut-off valve (V)
.
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.
