Granular:
There are numerous potential challenges that can happen on the granular
side due to the amount of use this portion of the unit sees. If product is not
spreading evenly or consistently, then look for a few things with your
hopper impeller or hopper diffuser. If there is build up at the end of the
Impeller tips or the tips are worn, this will cause an un-even and/or
inconsistent spread pattern. Another potential challenge is if the pattern is
not even when the Accuway is not part of the picture. This is sometimes
caused when granular product is moist and holding on longer than normal.
If granular product is leaking out from the hopper, determine where it is
coming from and look at this repair options. If the granular product is
leaking through the hopper shaft area, then your hopper busing is worn.
This will allow product to get in between the shaft and the hopper
bushing. If granular product is leaking through the hopper door area, then
Diffuser Guides are loose or worn allowing a gap between the door and
the hopper base. Also a potential factor is if the hopper cable is not
completely closing the hopper door.
When your hopper door cannot open, there are typically 3 things to look
at. One is that your hopper cable may be frozen and locked up, the ball
joint end may have broken off or there may be product jammed between
the hopper door and the base (due to loose door guides).
Spray System:
Liquid is dribbling from the tips. This effect is potentially caused by a few
things. If the Cap Gasket is missing, the 5 PSI Check Ball is stuck and not
closing or Diaphragm (rear of Nozzle Body) is damaged. Also check to
see if the Pressure Regulator is turned all the way up (no bypass).
Pressure not staying consistent. This is normally caused due to air being
introduced to the system. Air is introduced in a few ways through the
system. Air can come through one of the hose connections, the In-line
filter housing not being tight or not having a gasket to seal housing,
sucking air from an auxiliary tank or liquid level is too low.
