TROUBLESHOOTING
To reduce the risk of serious bodily injury, including
fluid injection, always follow the Pressure Relief
Procedure Warning on page 11 before checking or
repairing any part of the spray system.
WARNING
NOTES:
1.
Repairs, other than those for which instructions are
given on page 18, should be performed by a trained
and qualified repair agency.
2.
If your sprayer is not operating well, or will not oper-
ate 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.
3.
Remember, taking the time after each use of the
sprayer to perform all of the maintenance proce-
dures given on page 13 and 14 will help prevent down
time and costly repair bills.
