Maintenance

Routine maintenance is important to ensure proper operation of your sprayer. Maintenance includes performing routine actions which keep your sprayer in operation and prevents trouble in the future.

Activity	Interval

Inspect/clean sprayer filter, fluid inlet strainer, and gun	Daily or each time you spray
filter.

Inspect motor shield vents for blockage.	Daily or each time you spray

Fill TSL by adding through TSL fill point.	Daily or each time you spray

Inspect motor brushes for wear. Brushes must be 1/2 in.	Every 1000 gallons (3785 liters)
(13mm) minimum length. NOTE: Brushes do not wear at
the same rate on both sides of motor. Check both brushes.

Check sprayer stall.	Every 1000 gallons (3785 liters)
With sprayer gun NOT triggered, sprayer motor should stall
and not restart until gun is triggered again.
If sprayer starts again with gun NOT triggered, inspect
pump for internal/external leaks and check prime valve for
leaks.

Throat packing adjustment	As necessary based on usage
When pump packing begins to leak after extended use,
tighten packing nut down until leakage stops or lessens.
This allows approximately 100 gallons of additional
operation before a repacking is required. Packing nut can
be tightened without 0-ring removal.
