Detergent Siphoning Check Ball
Occasionally check ball in detergent siphoning system may
become stuck from storage, dried soap, or minerals in water.
The check ball can be freed by performing the following:
NOTICE Before performing this procedure, be sure you are
wearing safety goggles as described below.
WARNING Risk of eye injury.
Spray could splash back or propel objects
resulting in serious injury.
• Always wear indirect vented (chemical splash) safety goggles
marked to comply with ANSI Z87.1 when using or in vicinity of
this equipment.
• NEVER substitute safety glasses or dry-condition goggles for
indirect vented safety goggles.
1. Shut off engine and turn off water supply.
2. ALWAYS point spray gun in a safe direction, press red
button and squeeze spray gun trigger to release retained
high water pressure.
WARNING The high pressure stream of water that
this equipment produces could cut through skin
and its underlying tissues, resulting in serious
injury and possible amputation.
Spray gun traps high water pressure, even when engine is
stopped and water is disconnected, which could result in
serious injury.
• Keep high pressure hose connected to pump and spray gun
while system is pressurized.
• ALWAYS point spray gun in safe direction, press red button
and squeeze spray gun trigger to release high pressure, every
time you stop engine.
3. Remove detergent siphoning hose from barbed fitting
on pump.
4. Using a firm, blunt object 7/64" in diameter or smaller,
by at least 1" long, such as an Allen wrench, slowly
insert the object into the barbed fitting until you meet
resistance. This resistance is the check ball.
5. Slowly push down until you feel the ball move slightly,
push no more than 1/8". Slight pressure may be
required to free the ball.
6. Repeat steps 4 and 5 if necessary.
7. Reinstall detergent siphoning hose onto barb fitting.
8. Treat with PumpSaver as described in Protecting the
Pump during storage to prevent reoccurrence.
Check Spray Gun and Nozzle Extension
Examine hose connection to spray gun and make sure it is
secure. Test trigger by pressing it and making sure it springs
back into place when you release it. Do not depress red button
and test trigger. You should not be able to press trigger. Replace
spray gun immediately if it fails any of these tests.
