Problem
Possible Cause
Corrective Action
Pump delays before
starting
This is normal operation
None
Pump will not start
1.
Pump went to “sleep”* This hap-
pens if pump is plugged into power
source with gun switch in the “ON”
position
2. Worn electrical cord
3. Relay circuit failure in control box
1. Turn switch on and off at the gun
to restart the machine. (see Note
at bottom of this page for more
information)
2. Check cord and replace as needed.
3. Recommend factory repair of
components in control box.
Motor starts but will
not pump
Failure of drive mechanism
Check to see if rotor is turning. Repair or
replace failed parts as needed.
Motor struggles but
can’t turn pump
Stator adhered to rotor, caused by
running pump dry or with water only.
New stator tubes are very tight, which
can make it difficult to turn the rotor.
This condition is similar to placing
rubber on clean glass without water.
It is very hard to move the rubber
against the glass until there is some
lubricant to allow the rubber to glide
freely.
Add slurry to pump and turn pump
on and off several times (1 second
cycles). If this does not work, put a pipe
wrench on stator tube and apply shock
load while turning on motor. If still not
freed, remove stator tube and free the
rotor. Reinstall with liquid dish soap as
lubricant.
Pump is slow and
getting worse
Rotor or stator is worn
Rotor and stator are wear parts and must
be replaced from time to time.
Pump shows some
leakage
Mechanical seal is worn
Mechanical seal is a wear part and will
need to be replaced occasionally. Service
depends on the nature of
the material being pumped and the ser-
vice duty.

SLEEP
: Your Kodiak is equipped with a new safety feature to help prevent accidental pump
starts. This can happen when plugging the machine in to power while the switch at the gun and
the switch at the control box are in the ON position. If this happens the computer in the control
box recognizes this as an operator error and will go to “SLEEP”, this means it will not start the
pump. This condition is shown as
Stand-by
(see table 1 on page 4)
in the status LED on the
control panel. To override this and start the pump, simply turn the switch at the gun OFF then
ON again and the pump will start. Cycling the switch off and on, in effect, wakes up the control
box and reactivates the pump.
CONTROL BOX REPAIR PROGRAM:
If you have determined that you control box requires re-
pair take advantage of our affordable ROTABLE SPARE PROGRAM. See details on bottom of
page 5.
