5.2 MAINTENANCE
By following a careful service and main-
tenance program for your machine, you
will enjoy many years of trouble-free
operation.
5.2.1 FILTER CLEANING
The fl uid in the sprayer is continually be-
ing fi ltered through a screen fi lter in the
boom control feed line, agitation and
boom feed lines. The sprayer must have
clean water to prevent clogging of the
screens and check valves when in use.
These screens must be cleaned daily or
more often as required. To clean, follow
this procedure:
1. At the start of each day before the
water and chemicals are added,
the screens should be checked and
cleaned.
2. If there is water or solution in the
sprayer, close Valves 3 and 4 to
isolate the screens.
3. Loosen the fi lter bodies by hand.
Do not use a wrench as this could
damage the fi lter body.
4. Remove the screens and inspect
them for dirt.
5. Clean them using clean water.
6. Inspect for holes or tears. If there is
damage, replace it.
7. Install the screens and body to the
fi lter heads and tighten by hand.
Do not use a wrench as this might
damage the body. Do not over
tighten and crack the head.
8. Open the ball valves to allow the
solution to circulate.
9. Drain all screens before storage to
avoid freezing.
