Page 16: Troubleshooting
254 and 254OS Pneudraulic Installation Tools (HK1172) 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. NOTE: “Piston drift” is when the air piston is in the down position, but the hydraulic pull piston is not in the full-forward position. This causes an out-of-sequence condition. - Page 17 254 and 254OS Pneudraulic Installation Tools (HK1172) Limited Warranties Limited Lifetime Warranty on BobTail® Tools: Tooling, Part(s) and Other Items not manufactured by Huck: Huck International, Inc. warrants to the original purchaser that its BobTail® installation tools manufactured after HUCK makes no warranty with respect to the tooling, 12/1/2016 shall be free from defects in materials and part(s), or other items manufactured by third parties.
