Troubleshooting
1. Slow tool cycle.
a. Check air pressure and hydraulic pressure. Reference
Principle of Operation schematic on page 5 of this
manual.
b. Incoming air-line must be 3/8” ID minimum. If longer
that 20’, air-line should increase to 1/2” ID.
2. Tool will not pull rivet.
a. Air in hydraulic system; requires bleeding.
NOTE: Air entrapment is identifiable by sound. As trigger is
actuated, the normal “thud” produced by the power unit is
replaced by a metallic “clack”.
To bleed rivet tool, fill the reservoir, and:
1. Unhook RED air-line from power unit.
2. Lay tool in pan and remove bleed screw.
3. Allow fluid to flow until it is free of bubbles.
If condition persists, replace the seals.
b. 1. Unhook RED air-line from power unit.
2. Attach Filler / Bleed Pump Assembly to tool
hydraulic hose.
3. Remove bleed screw on Rivet Tool.
4. Pump the Bleed Pump until bubbles quit coming out
of the bleed port on the tool.
Always check the simplest possible cause (such as a disconnected air hose) of a malfunction first. Then proceed logically,
eliminating other possible causes until the cause is discovered. Where possible, substitute known good parts for suspected
defective parts. Use this troubleshooting information to aid in locating and correcting trouble.
