Troubleshooting

WARNING

To reduce the risk of injury, including fluid injection, al- ways follow the Pressure Relief Procedure Warn- ing on page 11 before checking or repairing any part of the spray system.

NOTE: Repairs, other than those for which instructions are given on page 18, should be performed by a trained and qualified repair agency.

NOTE: If your sprayer is not operating well, or will not op- erate at all, check for obvious problems first. Follow the Startup procedure exactly (see page 11). Then if the sprayer won't start, use the Troubleshooting Chart for help in identifying the possible cause.

NOTE: Remember, taking the time after each use of the sprayer to perform all of the maintenance procedures given on page 13 and 14 will help prevent down time and costly repair bills.
