The hand piece fails to deliver grease when on
the high volume setting
(a) There is dirt on the valve inlet seat (24).
(b) Operating plunger control (25) sticking in
control body assembly (26).
(a) IMPORTANT: This problem will result in
a decreased volume of grease being dispensed
per shot.
Remove control body (26) and tap out valve
inlet seat (24), O’ Ring (31), ball (30) and
spring (27). Clean the ball and seat and
replace in the following order – spring, ball,
O’Ring, valve seal and control body.
(b) Replace the control body assembly (26).
Control push rod in the control body leaks
O’Ring (31) is worn
Remove control body assembly (26) from the
hand piece. Also remove the operating control
plunger (25) from the control body and replace
with spare part kit number 6336N-SPK7

the
seals out and use spare part kit number
6336N-SPK8. Be careful to replace the
components in the following order – O’Ring
(13) and washer (12). Locate O’Ring (11) on
to the hand piece casting (8). Reassemble ball
socket retainer on to the hand piece.
When on the high volume setting, the hand
piece is too slow and too hard to operate
(a) Spring (16) may have weakened or collapsed
and are blocking the flow of grease
(b) The grade of grease being used is too heavy.
(c) Too much comprehension on the outlet
spring (2).
(a) Replace spring (16) and use spare part kit
number 6336N-SPK5 and valve stem spare part
kit number 6336N-SPK1.
(b) Change to an NLGI2 or lower viscosity
grease.
(c) Reset the spring keeper screw as noted in
the 2.5kg grease kits coupler leaks section. If
the problem persists, you will need to replace
the outlet body assembly.
GENERAL INSTRUCTIONS
ALWAYS When the gun has been serviced and the trouble found to be caused by dirt in the valves, the pump unit should also be
cleaned out thoroughly to eliminate the dirt at its source.
CLEANLINESS Dirt and foreign matter (lint, etc.) can seriously affect operation and machinery. Dismantling and reassembly of
this unit should only be attempted in clean conditions.
