Troubleshooting
Hydra SprayTrax Manual

This power sprayer troubleshooting section shows how to diagnose and resolve problems that
may occur in the course of normal operation. If you experience a problem, take the steps
indicated for the applicable diagnosis. When you can't determine the cause of a problem or
if you have any difficulty, please feel free to contact your nearest dealer or this company's
sales office. Please have the following information ready: 1. Model designation 2. Serial
number 3. Description of problem (What happened? What were you doing when it
happened? What were the conditions when it happened?) For items marked with *, please
request adjustment or repair from your nearest dealer or from this company's sales office.
WARNING:
Do not change the setting of the screw that is under the cap on the top of the
pressure regulator knob. This screw absolutely must not be changed, since that will raise the
pressure above rated specifications, damage the machine, and possibly cause injury.
