1.A The plunger adjusting screw (18) has been screwed in too far. = Loosen the=20 locknut (17) and screw the plunger adjusting screw (18) out until a = uniform flow=20 of grease occurs.
2.A There could be three causes:
There is dirt under the valve =

the inlet body (14). Unscrew the inlet body (14) from the gun body (11) =
and then=20
unscrew the valve insert (8). Remove the valve spring (7) and steel ball =
(6)=20
before cleaning the ball seat and reassembling.
The plunger screw =

reassembling.
3.A There could be two causes:
The trigger (22) has been set =
incorrectly.=20
Refer to problems 1 and 2(b) above.

from the gun body (11), and then unscrew the extension tube (9) and =
swing the=20
trigger (22) away so the plunger guide bush (1), plunger (2), glyd ring =

sealing the tube to the non return body (5).
4.A The plunger o'ring (4) is damaged and needs to be replaced. Order = BJ1s.=20 Remove the extension tube (9) and swing the trigger (22) away so the = plunger=20 guide bush (1), plunger (2), glyd ring (3) and plunger o'ring (4) may = all be=20 removed. Replace damaged parts and reassemble. Apply Teflon tape (or = thread=20 sealant) to the extension tube (9) thread for sealing the tube to the = non return=20 body (5).
5.A The swivel seals (25 & 26) are damaged and the entire swivel = needs to=20 be replaced. Order ZSB.
6.A The threads are not sealed. Disassemble and apply Teflon tape (or =
thread=20
sealant) to the male thread (2-3 layers should =
suffice).
