TECHNICAL PROBLEMS
Before looking for a hammer problem, look for a problem in the installation like bad quick couplers or a
plugged filter [see page M3 for how to check the installation].
Make sure that the hammer has not been hooked up backwards.
Make sure that the hammer has the proper tool.
Make sure that the down pressure has been applied.
Make sure that no valve(s) are closed.
For any other problem, refer to the Trouble Shooting page M1. If you cannot identify the problem, BEFORE
calling your TRAMAC dealer, collect the following information. A complete diagnosis cannot be done without
it.
Low Pressure Gauge 0-160 Psi
