IMPORTANT INFORMATION
Read this information carefully before use.Your safety
is important to us. Please read and follow all operating
and safety instructions listed below.Make sure all
operators have adequate access to the following
instructions.
CAUTION
This is a 50:1 ratio high pressure grease pump. Because
of the high pressures developed by this pump, the
possibility of fluid injection into the flesh, or eyes, is a
potential hazard.
Never allow any part of the human body to come in front
of, or in direct contact with a material outlet. Never point
the nozzle of the gun at yourself or anyone else.
Most injections occur because of component rupture. Never
exceed the pressure rating of any component in the
system. Remember, fluid pressure generated is fifty times
the air inlet pressure.
Weak, worn or damaged hoses are also a hazard. Before
operation check hoses for signs of wear, leaks or loose
fittings. Tighten all fluid connections regularly and replace
weak or damaged hose. Your personal safety and well
being are at stake.
If accidental injection should occur, seek immediate
emergency medical attention.
Do not use air pressure greater than 1035kPa /150psi /
10.3bar
Do not hit the unit if it fails to operate.
CAUTION
Before attempting any maintenance or repairs of this
product, disconnect air supply then squeeze gun trigger
to release pressure.
ASSEMBLY
This carton contains an Air Motor / Suction Tube assembly
(Pump unit), Lid, Follower, High Pressure Grease Hose,
B2 Booster Gun / Swivel assembly and a plastic bag
containing 3 slotted screws and an instruction sheet.
1) Remove the components from the protective packaging.
Reposition the 3 lid positioning screws so the threaded
ends are flush with the inside of the lid (Fig 1).
2) Slide the suction tube through the lid. Line up the holes
in the lid with the threaded holes in the air motor base,
so that the grease outlet of the pump faces one of the lid
handles (Fig4). This allows easy fitting and removal of
the air -line. Secure the lid to the air motor with the 3
slotted screws provided (Fig 2).
1
3) Remove the lid from the grease container. This grease
pump is recommended for use with grease up to and
including NLGI No.2. Heavy grades of grease or cold
temperatures can result in operating difficulties.
4) Place the follower plate in the grease container with the
follower handle and boss facing upwards (Fig 3). Push
the follower plate down onto the grease until some
grease is forced through the centre (boss) hole.
8) Turn on your air supply and press the reset button
(fig 1). Hold the B2 booster gun near a waste container
(to collect the test grease) and squeeze the gun trigger.
The air motor will start to operate and the factory test
grease will appear followed by air (in high pressure
grease hose), followed by your grease. Tighten
connections as required.
OPERATION
1)
Before connecting the air supply check that all fittings
have been tightly fastened and all hoses are checked
for wear and or damage.
2)
Fully depress the reset button (fig 1), add air cock and
recommended air filter (as described in item ‘2’ of
assembly section) then connect the air supply. The
optimum pressure range is 550 to 700 kPa (80100psi / 5.5–7 bar).
3)
When air is connected to the pump and is turned on,
the air motor will start operating, this will allow grease
pressure to build, which pushes grease through the
pump and hose to the grease gun until ‘stall’ pressure
is reached,at this pressure the pump will stop.

For grease delivery press the trigger on the booster
gun. To stop grease delivery release the trigger on the
booster gun. When the trigger is released the grease
flow will stop and the pump will again build to ‘stall’
pressure and stop.
5) Insert the suction tube through the follower boss and
push the lid / pump assembly down until the lid sits
squarely on top of the grease container. Screw in the lid
positioning the thumb screws equally, until finger tight.
The lid must be centrally located on the grease container.

High Pressure
Grease Hose
To grease, connect the B2 booster gun coupler to the
grease nipple then squeeze the trigger. Normally, the
air motor will operate and grease will be pumped
through the nipple. If the grease nipple is blocked, the
air motor will stop (stall). If this happens do not
remove the gun from the nipple, just squeeze
the trigger on the B2 gun three or four times. The B2
booster gun has a boost facility which allows the
grease pressure delivered to the grease nipple to be
boosted and will clear most blocked nipples.
(Fig 4)
6) Apply thread tape or other thread sealant to both ends of
the high pressure grease hose. Pass the hose through
the lid assembly and screw the hose into the pump outlet
tightly ( fig 4). Screw the other end of the hose into the
ZSB swivel on the inlet of the B2 booster gun.
7) Before connecting the air supply the customer should
add a “stop” compressed air cock. The air cock must be
a ¼ turn type ( allowing quick closure) and should be
located close to the body of the pump and be easily
recognised. There is a wire mesh strainer located
inside the brass air inlet. It is recommended that a
micro- fine (5 micron) in line air filter be fitted to ensure
maximum efficiency of this pump. Then connect you
airline to the swivel type, brass air inlet.
CAUTION
It is important to read all warnings and operating
instructions before use.
Note: The B2 booster gun creates the extra pressure and
not the pump.
(Fig 5)
5)
Remove the coupler from the grease nipple by first
tilting (to release any pressure) then a twist and pull
motion. Loosen the black coupler cap if difficult to
remove.
CAUTION
Use the lid handles to move the greasing unit. Do not
move the pump by pulling the air or grease hose.
2
Note: At the end of the day or if the pump is not going to be
used for an extended period of time, disconnect the air
supply and release the grease pressure ( squeeze the
gun trigger till the grease ceases to flow).
CAUTION
Before carrying out any maintenance, disconnect the
air and release the grease pressure by pressing the
trigger on the B2 Booster gun until the grease flow stops.
MAINTENANCE
1) Keep your pump, high pressure grease hose and
air-line clean.
2) Inspect your pump, high pressure hose and air-line
weekly for any signs of deterioration or damage. ie: hose
seperation, hose distortion etc. (Replace any suspect or
damaged components as required).
Note: If piston rod is damaged, premature wear can occur
to piston rod seal (18).
11) Remove the strainer tube (53). there are spanner flats
on the bottom of this tube.
12) Remove the circlip (52), primer (51), valve seat (50)
and valve spacer (49).
13) Use a pipe wrench or vice grips to remove the tube
link (48).
Note: Repair any damage caused to the tube link with a file
and emery paper.
14) Grip the high pressure suction tube (43), with a pipe
wrench, as close as possible to the top. Remove the
high pressure suction tube.
Note: There is thread sealant on the insert / tube thread.
3) Every 2 weeks or sooner if the pump is used every day
apply a few drops of light oil, (sewing machine oil is
ideal), to the air inlet of the pump.
15) Pull out the primer (42) and piston rod assembly (13)
from the base (21). Use this rod assembly to push the
washer (44), Seal (45), and cylinder (46) out of the high
pressure suction tube (43).
4) Check the top seal condition hole (Fig 4). A small
quantity of grease indicates seal lubrication is OK. A
continuous ‘worm’ of grease indicates a worn seal.
(Replace if required).
16) Remove the gland nut (17), then the botton (short)
poppet valve assembly (27), including o’ring (1), (3)
from the cylinder base (21).
PUMP UNIT DISASSEMBLY
The following procedure should be followed for pump
disassembly to carry out routine maintenance. Refer to
the exploded parts diagram and listing on the following
pages.
17) Use the primer / piston rod assembly to push the piston
rod seal (18) from the cylinder base (21).
18) Knock out the 2 roll pins (38) with a pin punch.
Unscrew the primer / piston rod assembly and remove
the steel balls (39) and suction spring (41).
PUMP RE-ASSEMBLY
1) Disconnect the air supply and release the grease
pressure by squeezing the B2 booster gun trigger.
2) Remove the high pressure hose and lid from the pump
unit.
3) Remove 4 screws (22) holding cylinder (7) to the base
(21). There’s a slot in the base near the valve body (30).
4) Remove the cylinder (7) from the cylinder base (21).
1) Ensure that all parts have correct orientation. If the parts
are assembled upside down, the pump will not work.
Check the parts diagram for the correct orientation.
Note: Assembly of the pump is a reversal of disassembly
procedure.
2) Apply thread sealant (loctite or similar) to insert (23)
and primer rod (42) threads.
5) Remove cover screw (6) and valve body cover (31).
6) Remove 6 screws (33) holding valve body (30) to
cylinder (7) pull off valve body assembly and valve
gasket (28).
7) Pull out 2 brass pins (32) from valve body. Lever out
plugs (29) and (36).
8) Gently push spool (34) out of valve body. Be careful
when removing “o” rings (3) and (14).
9) Remove top (long) poppet valve assembly 2,4,5 and
‘o’rings (3).
3) Fill the strainer tube (530 with grease for initial prime.
Hand tighten the suction tube (43), tube link (48) and
strainer tube. Use the spanner flats on the strainer
tube to tighten all three tubes.
4) Ensure that all o’rings, particularly in the valve body (30)
and the poppet valve (2), (27) areas, sit square.
5) Apply Light grease eg. petroleum jelly to the o’rings (24),
(25) and piston seals (10) before fitting the cylinder
(7) to the cylinder base (21).
10) Hold the hex section of insert (23) horizontally in a
vice, hold piston rod (13) as close as possible to the
