Priming

Overview
Priming is the act of removing air and intro-
ducing grease into the pumping mechanism.
Whether a gun primes is dependent on:
– viscosity of grease
– temperature of grease
– condition of gun
Operate gun
In most cases gun will prime simply by oper-
ating its lever (4) several times.
Should grease fail to appear, head assem-
bly must be bled.

E Follower rod

Force prime

This process manually assists air within head
assembly to be bled at bleed valve.
1 Pull follower rod outward from cylinder
cap. At the same time, rotate rod to allow
locking tabs access through back-up
plate († Fig. 3, page 5).
2 Rotate rod and allow locking tabs to con-
tact back-up plate.
3 Move gun's lever (4) to the open position.
4 Depress bleed valve and at the same
time push follower rod into gun's cylinder
(† Fig. 4, page 5).
Once air is eliminated:
5 Operate lever of gun several times.
Once grease appears:
6 Push and turn follower rod into cylinder.

Loss of prime
A situation may arise when only a portion of
grease within gun dispenses.
prime is due to an air pocket in the grease.

The most common cause for this loss of
In addition to the reasons previously
– viscosity of grease
– temperature of grease
– condition of gun
Additional conditions are:
– damaged cartridge
– type of grease (Certain synthetic
greases can react with follower causing
it to swell.)
