What to do if Macnaught P3 POWERLUBE Tools gun leaks continuously out of the coupler?
If the gun leaks continuously out of the coupler, it could be due to: * Incorrect trigger adjustment: Adjust the trigger to allow 3 to 6mm (1/8” to 1/4”) free movement. * Bent or damaged plunger: Replace the plunger (60).
What to do if Macnaught Tools air motor cycles intermittently when not using the pump?
If the air motor cycles intermittently when you are not using the pump, consider these potential causes: * Grease leaking at hose and/or swivel connections: Check all connections, use thread sealant, and tighten any leaking connections. * High pressure seal worn or damaged: Replace the high pressure seal (45).
How to troubleshoot Macnaught P3 POWERLUBE air motor that runs but does not pump grease?
If the air motor runs but the grease is not being pumped, the issue may be: * The grease is too thick or too cold: Use NLGI no 2 or thinner grease. Store grease in a warm place. * The grease container is damaged causing the follower to stop: Repair or replace the container, ensuring the follower can move freely.
Why Macnaught Tools air motor runs slower than normal?
The air motor may be running slower than normal because the air pressure is too low. Increase the air pressure; the minimum is 400 kPa/60 psi/4 bar, and the maximum is 1000 kPa/150 psi/10 bar.
What to do if Macnaught P3 POWERLUBE air motor does not operate, but will cycle when the reset button is pressed?
If the air motor does not operate but cycles when the reset button is pressed, the issue could be: * The spool is jammed in the valve body: Push the reset button. If the motor starts, disconnect the air line and apply 3 or 4 drops of light oil to the air inlet of the pump. If the motor does not start, replace the spool and clean valve bore. When re-assembled, apply 3 or 4 drops of light oil to the air inlet of the pump. * Top poppet spring is fatigued: Replace the top poppet spring.
Why Macnaught P3 POWERLUBE Tools air leaks continuously from the valve body cover?
To address continuous air leaks from the valve body cover, replace the cup seals and/or piston.
What does it mean if grease leaks out of the seal condition hole on Macnaught P3 POWERLUBE Tools?
If grease leaks out of the seal condition hole: * A small quantity of grease indicates the seal lubrication is OK, and no action is required. * A continuous ‘worm’ of grease indicates the seal is worn or damaged, and you should replace the Piston rod seal (18).
What to do if Macnaught P3 POWERLUBE air motor does not operate or cycle when the reset button is pressed?
If the air motor does not operate or cycle when the reset button is pressed, it indicates that the lower poppet spring is fatigued. Replace the bottom poppet spring to resolve this issue.
