3. Using a firm, blunt object 2mm (7/64") in diameter or
smaller, by at least 25.4mm (1") long, such as an Allen
wrench, slowly insert object into barbed fitting until you
meet resistance. This resistance is the check ball.
4. Slowly push down until you feel ball move slightly,
push no more than 3mm (1/8"). Slight pressure may
be required to free ball.
5. Repeat steps 4 and 5 if necessary.
6. Reinstall detergent siphoning hose onto barb fitting.
7. Treat with PumpSaver as described in Protecting the
Pump during storage to prevent reoccurrence.
Spray Tip Maintenance Figure
Clean spray tip to correct excessive pump pressure
caused by a clogged spray tip:
1. Turn off water supply.
2. Remove spray tip from end of nozzle extension.
3. Use a small paper clip to free any foreign material
clogging or restricting spray tip (B).
4. Reinstall spray tip into nozzle extension.
O-Ring Maintenance Figure
The use of a lubricant (petroleum or synthetic grease)
helps seat o-rings providing an improved seal. Apply
lubricant to o-rings prior to assembling garden hose to the
pump inlet (A), high pressure hose to pump outlet (B), high
pressure hose (C), spray gun (D), and nozzle extension (E).
Purchase an O-Ring Maintenance Kit by contacting a
Briggs & Stratton Authorized Service Dealer. Refer to the
instruction sheet provided in the kit to service your unit's
o-rings. NEVER repair leaking connections with sealant of
any kind. Replace o-ring or seal.
Changing Pump Oil
NOTICE When changing pump oil, use only high quality
SAE 30 weight oil. Use no special additives.
1. Clean area around brass oil drain plug at bottom of
pump.
2. Remove oil drain plug. Drain oil completely into an
approved container.
3. When oil has completely drained, install oil drain plug
and tighten firmly.
4. Clean area around pump oil dipstick. Remove dipstick
and fill pump with recommended oil (approximately
355 ml (12 oz.)) to "Full" mark on dipstick.
5. Install pump oil dipstick.
