Periodic Maintenance
1. Check power cord for any breaks, separations, or cuts. Make sure the ground pin on the connector is intact
or the machine will be unsafe. Make sure the ground pin on all three prongs on the twist lock connector
are intact.
2. Check for plugged nozzles when using tools. If streaking occurs during cleaning, a plugged nozzle
may be the cause. A plugged or partially plugged nozzle can be identified by holding the tool 5-7" above
the surface and checking for an even spray pattern. To clean a plugged nozzle, remove the nozzle and
direct pressurized air backwards through the nozzle or backwash the nozzle with water. A convenient
method is to insert the nozzle into a garden hose ball valve, tighten the ball valve to a faucet, and turn on
the water. (Ball valves are available, part #7AX020). Inspect nozzle and repeat cleaning procedure, if
necessary. Discard nozzles that cannot be cleared. Tool nozzles wear and must be replaced after 200-250
hours of use.
3. Occasionally open the base and inspect hose and other connections for leaks. Repair or replace any
leaking parts. Always disconnect power cord, before removing side panels.
4. It is very important to monitor machine operating hours for proper maintenance of the motors and
pumps. After 700 hours of operation, the vacuum motor brushes should be inspected by an authorized
repair station and replaced if worn (length is .5 inches or less).
5. Check vacuum motor performance using a vacuum gauge. Place this gauge on the tank inlet fitting with
the vacuum turned on. Water lift should be between 135 and 150 inches. If the reading is lower, check for
air leaks in the tank, cover gasket, and drain hose.
6. Check pump performance occasionally against built-in pressure gauge. Pump running pressure on the Pro
500 should be 500 + 10 p.s.i, Pro 750 should be 750+ 15 p.s.i. If the pressure is outside of this range, call your
dealer or authorized service center. After 400 hours, the pump valves should be replaced. After 700
hours of operation the pump cam bearing and plunger should be replaced. The pressure regulator should
be rebuilt after 400 hours of operation.
TROUBLE SHOOTING GUIDE
Vacuum or pump will not run Check that electrical cord is firmly seated in wall outlet.
Check and reset building circuit breaker if tripped.
Check vacuum/pump switch. It should be in the “on” position.
Trips building circuit breaker Circuit is overloaded – move cord to a different wall outlet.
If using an additional extension cord, make sure it is in good condition,
less than 70 feet long and AWG#10 gauge or heavier.
Check plug end and cord for damage.
Vacuum won’t run. Check vacuum switch. It should be in the “on” position.
Check fuses and replace if tripped. (located on base of machine)
Pump won’t run Check pump switch – it should be in the “on” position.
Check pump circuit breaker (5 amp) and reset if tripped.
Check fluid level, must have at least 5 gallons in tank.
Check fluid level inside of Main Filter Cage – pump float must be at highest
position to operate.
If fluid is lower inside filter, drain tank and remove and clean filter.
Pump tries to run and then blows circuit breaker Check power cord for frayed, cut or worn spots.
If using an extension cord,make sure it is in good condition, less than 70
feet long and AWG #10 gauge or heavier.
Check pump static PSI – must be 400 psi or less
Check wall outlet voltage. If below 105 volts, pump will not work.
Pump starts and stops Check for dirty Main Filter. Water level should be the same inside and
outside of filter.
Check for sticking pump float.
Check fluid level – must have at least 5 gallons in tank.
