PACECART 3 TROUBLESHOOTING
SYMPTOM
REPAIR SUGGESTIONS
Audible humming/vibration coming
from motor assembly.
Disconnect electrical power from the cart to avoid motor damage. Remove the pump and clean it, or unfreeze it by the
method described below. (The last suggestion at the bottom.)
OlyBond500 does not flow from gun.
Check to see if gun, whips or hoses are clogged. Clear any clogs and repeat Steps 2, 4, 5 and 6 of operating instructions.
AND:
Make sure pumps are working.
Machine pumps unequal amounts
of materials 1 and 2.
Flow might be disrupted by clog. Make sure the materials are at the correct application temperature.
AND:
Check hose for even flow.
AND:
Clean gun.
AND:
Check part 1 pump for blockage.
OlyBond500 does not foam up.
Gun may not be delivering equal amounts of material (from boxes 1 & 2), thereby preventing chemical reaction. Check
for clogs in hoses or gun.
AND:
Check boxes for inadequate material levels.
Material foams up, but has no
holding power.
Foam may be off ratio. Check for equal flow of Part 1 & Part 2.
AND:
Material may have been frozen. Dispose of it and replace with fresh material.
Motor turns but pump does not
supply material.
Pump may be clogged or broken. Call 800.633.3800 or 413.789.0252 for assistance.
Motor does not turn.
Make sure on/off switch is in “on” position.
AND:
Make sure breaker switch is on.
AND:
Pressure switch may be activated. Open valves to relieve pressure in
hoses.
If none of these remedy the situation, check power source. Turn off PaceCart 3 immediately as insufficient power will
damage the motor.
Be sure your power cord is no longer than 75 feet (23m).
AND:
Be sure your power source is delivering power at 110-
125v, 15 amp.
AND:
Check for competing equipment on the same line.
AND:
Pump may be frozen. With the motor
turned off- remove the two pump mounting bolts, pull the pump away from its shaft coupling and use a tool to rotate the
pump shaft back-and-forth until the pump shaft freely turns.
