Troubleshooting

Due to the close clearance between the piston and the cylinder, external matter in the air supply may cause the piston to stick. To avoid this issue, remove the cylinder sleeve, drive the roll pin out of the cylinder and inlet, and remove the piston from the cylinder. Thoroughly clean all parts, blow dry and lubricate with the recommended air tool oil. Check the clearance and the free movement of the piston and reassemble the tool.

To remove the sleeve valve, remove the O-ring between the retaining ring and the threads on the inlet, remove the retaining ring, set the sleeve valve to OFF and pull the valve off the inlet. Inspect the O-rings, replace if worn, re-lubricate and re-assemble. Do not over-lubricate the O-ring in the counterbored air port, there is a risk of impeding the air flow.
