Troubleshooting

Engine:

• Not starting. There are a few reasons as to why your engine fails to start. If the engine does not turn over,
then the battery could be dead, bad connection to the battery wires, keys which may be bad, 30 AMP fuse
on the wiring harness (orange wire) may be blown or the starter solenoid may be bad (you will hear the
starter solenoid trying to click on, but nothing is happening). Another common reason for a unit not
starting is after unit has been washed. Water gets into the spark plug boot and gets the spark plug wet. Pull
spark plug boot and dry (spray WD-40).
• Engine turns over but doesn't start. There are a few reasons as to why your engine will turn over but not
start: loose or bad spark plug, water in fuel, choke partially closed or wet and/or foul plugs. Check for fuel..
• Engine won't stay running. Few things to look for if your engine does not stay running are clogged fuel
filter, clogged and/or dirty air filter, water in fuel or low fuel.

Hydraulics:

• Hydraulic system making loud noise when running. This could be caused by a couple of things. The most
common is if there is air in the system. This can be caused when changing out a hydro pump, replacing a
hydraulic hose or having a loose fitting on the intake lines. If air is not present, check for low levels in the
system. This happens when there is a leak in the hydraulic system somewhere or hydraulic fluids were just
changed and did not get back to the proper fill level.
• Need to tow my unit; what do I need to do in order to not ruin my hydro pumps? There are Tow Valves
on each of the hydro pumps (hex head with hole running through it on the left side rear of the hydraulic
pump) that needs to be turn at least 1 ½ revolutions counterclockwise to open the hydraulic system
(but NEVER remove). Once the unit is brought to a desired location, remember to tighten the tow
valves back tight (clockwise).

Tracking:

Unit not tracking straight when pushing both control arms to the speed bar. This is caused when the linkage
to the hydraulic pump is not even or a hydraulic pump is going bad. Traditionally the linkage needs to be
adjusted so that they both have the same amount of pull. If it is pulling to the left, the left hydraulic pump
linkage is longer than the right; you can either adjust the right to a longer length, or adjust the left to a shorter
length to match the right.

Granular:

• There are numerous potential challenges that can occur 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 uneven 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 the repair
options. If the granular product is leaking through the hopper shaft area, then your hopper bushing is worn.
This will allow product to get in between the shaft and the hopper bushing. If granular product is leaking
