1. SAFETY
WARNING! Disconnect the grease pump from the air supply before changing accessories, servicing or performing any maintenance.
WARNING! Ensure correct air pressure is maintained and not exceeded. Recommended pressure 115psi.
WARNING! Turn off air supply and de-pressurise the control nozzle before removing the pump unit from any installation or mobile
system. Failure to comply with this instruction may damage the unit and will invalidate your warranty.
WARNING! DO NOT tamper with or open pump unit. To do so will invalidate your warranty.
9 Maintain pump in good condition (use an authorised service agent).
9 Replace or repair damaged parts. Check the grease bucket to ensure it is not damaged. A damaged grease bucket will cause the follower
plate to jam.
9 Use recommended parts only. Non authorised parts may be dangerous and will invalidate the warranty.
9 Wear appropriate protective clothing. When handling lubricants refer to manufacturer’s instructions and conform to local regulations.
9 Use the pump in an appropriate working area for its function. Keep area clean and tidy and free from unrelated materials and ensure
there is adequate lighting.
9 Keep air hose away from heat, oil and sharp edges. Check air hose for wear before each use, and ensure that all connections are secure.
9 Maintain correct balance & footing. Ensure floor is not slippery, wear non slip shoes.
9 Keep children and unauthorised persons away from the working area.
9 Dispose of waste grease in accordance with local authority regulations.
9 When not in use ensure the air supply is turned off.
9 When not in use, disconnect the unit from the air supply. Clean the unit and store in a dry, safe, childproof location.
8 DO NOT allow unauthorised persons to operate the pump.
8 DO NOT point grease gun at yourself, other persons or animals.
8 DO NOT pull the grease pump unit by the hoses, or yank the hose from the air supply.
8 DO NOT force the pump to achieve a task it was not designed to perform.
8 DO NOT operate the pump when you are tired, under the influence of alcohol, drugs or intoxicating medication.
2. i INTRODUCTION
Fitted with high efficiency 50:1 air motor. Workshop tested reliability. Supplied with safety regulator to prevent over pressurisation of
pump unit. Fitted with a follower plate to prevent pump unit cavitation and ensure a smooth flow of grease. Includes SAE100R2AT rated
grease hose, z-swivel, control valve and bucket trolley. The AK452X.V4 and AK453X.V3 are designed for use with most popular multi-
purpose greases to NLGI No.2 specification made with light to medium base oil viscosities. The flow rate (delivery) performance will vary
dependant upon the lubricant viscosity, temperature, additives, and on the pipelines used.

4.2.1. Attach the wheels (F) and castors (G) to the platform (A) using the nuts and bolts
provided.
4.2.2. Slide the support bracket (C) then the securing hook (D) onto the handle (B).
Attach the handle (B) to the platform (A) and secure with the grub screw (E).
4.3. Assemblingthepumpunit(refertofig.2).
WARNING! Clean new delivery lines ensuring all metal shavings have been
removed before connecting the pump and control valves. Any dirt in the inlet hoses
will damage the unit and may invalidate your warranty.
NOTE: It is recommended that PTFE sealing tape is used on all connections.
4.3.1. Place the grease bucket (12) onto the platform of the trolley.
4.3.2. Remove the original lid supplied with the grease bucket and store it for future use.
4.3.3. Insert the follower plate (1) into the top of the grease bucket (12) with the handle
uppermost and settle it down onto the surface of the grease. The follower plate
is drawn down by the suction of the air pump and compresses the grease during
operation to prevent air pockets.
4.3.4. Secure the grease bucket to the trolley by sliding the securing hook over the rim of
the grease bucket and locking with the hand screw.
4.3.5. Place the dust cover (2) onto the grease bucket (12), but do not secure.
4.3.6. Lower the pump assembly through the support bracket on the trolley.
4.3.7. Align the pump shaft (3) over the dust cover (2) and allow the shaft to pass through
the dust cover (2), and the follower plate (1) then sink down to the bottom of the
grease bucket (12).
4.3.8. Align the position of the trolley support bracket so that the pump shaft is vertical
and perpendicular to the trolley base and the support bracket is set to the correct
position.
4.3.9. Tighten the trolley support bracket hand screws and tighten the three butterfly
screws to secure the dust cover (2) to the grease bucket (12).
4.3.10. Connect the air regulator (11) and air oiler (9) together using the long bolts and
Nuts provided (The nuts slide into the recesses in the front and back of the
regulator body). Ensure that the air flow arrows moulded into the top of each unit
body are pointing in the same direction and that both arrows are pointing towards
the pump air inlet. The air oiler (9) should be situated between the air regulator (11)
and the pump (10).
4.3.11. Screw the circular pressure gauge (8) into which ever side of the regulator (11)
is most convenient for reading. Seal the unused mounting position using the
blanking plug provided.
4.3.12. Connect the regulator (11) assembly to the pump air inlet using the 1/4”BSP fitting
(6) provided.
4.3.13. Connect the Z-swivel (14) to the grease gun (13) and connect the grease hose (4)
to the Z-swivel (14). Connect the other end of the grease hose (4) to the grease
outlet (5) on the pump.
5. OPERATION
5.1. Turn the air pressure on and check there are no leaks in the system.
5.2. Adjust the air pressure using the air knob on top of the air regulator. Unlock the knob by pulling it upwards and turning it until the gauge
indicates the recommended operating pressure of 115psi. Push the knob down again to lock it. It is important to maintain the correct
operating pressure to ensure that the control valves and connectors are not damaged, and to prevent leakage in the delivery lines.
5.3. Prime unit by operating grease control valve until lubricant emerges from end of the gun. The unit is now ready for use.
5.4. When not in use, turn the air supply off and disconnect the unit from the air supply. Store in a safe, clean, dry, childproof location.
6. MAINTENANCE
WARNING! Disconnect the pump from the air line before attempting any service or maintenance. Replace or repair damaged parts.
Use genuine parts only. Non-authorised parts may be dangerous and will invalidate the warranty.
