Page 7: Principle Of Operation
2013 & 2014 series Pneudraulic Installation Tools (HK978) Principle of Operation PULL STROKE: When the trigger is PULL Piston pressed, the throttle valve moves Spring down to the PULL position, and pressurized air is directed to the bottom of the air piston, causing it to move upward. The air above the Hydraulic Hydraulic Damper air piston is exhausted and directed Piston Rod Piston Rod Valve through the center of the throttle valve and out the bottom of the tool.

Page 21: Troubleshooting
2013 & 2014 series Pneudraulic Installation Tools (HK978) Troubleshooting Always check the simplest possible cause (such as a loose or disconnected trigger line) 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. 1. Tool fails to operate when trigger is pressed. 5. Tool has piston drift. Air-line not connected or air pressure too low. Loose collet crashing into the front of the anvil b. Worn or damaged throttle valve O-rings. causing the relief valve to open. Tighten the Broken throttle valve cable. collet. See the Fill and Bleed section. b. Worn or damaged return pressure relief valve.
