Engine Maintenance - Briggs & Stratton BPW2000 Operator's Manual

Pressure washer parts should be kept clean to reduce the risk of overheating and
ignition of accumulated debris.
• Use a damp cloth to wipe exterior surfaces clean.
NOTICE Improper treatment of pressure washer could damage it and shorten its life.
• DO NOT insert any objects through cooling slots.
• Use a soft bristle brush to loosen caked on dirt, oil, etc.
• Use a vacuum cleaner to pick up loose dirt and debris.
check and clean inlet screen
Examine the screen on the pump's water inlet. Clean it if the screen is clogged or
replace it if screen is damaged.
check High Pressure Hose
The high pressure hose can develop leaks from wear, kinking, or abuse. Inspect the
hose each time before using it. Check for cuts, leaks, abrasions or bulging of cover,
damage or movement of couplings. If any of these conditions exist, replace the hose
immediately.
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.
• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST equal or exceed maximum pressure rating of unit.
check detergent siphoning tube
Examine the detergent tube and clean if clogged. The tube should fit tightly on the
barbed fitting. Examine the tube for leaks or tears. Replace the tube if damaged.
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 2 mm (7/64") in diameter or smaller, by at least 2.5
cm (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 3
mm (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
Examine the hose connection to the spray gun and make sure it is secure. Test the
trigger by pressing the red button and making sure the trigger "springs back" into
place when you release it. You should not be able to press the trigger without pressing
the red button. Replace spray gun immediately if it fails any of these tests.

nozzle Maintenance
A pulsing sensation felt while squeezing the spray gun trigger may be caused by
excessive pump pressure. The principal cause of excessive pump pressure is an orifice
clogged or restricted with foreign materials, such as dirt, etc. To correct the problem,
immediately clean the orifice using the tools included with your pressure washer and
follow these instructions:
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 nozzle extension from spray gun.
4. Twist nozzle clockwise to stream position. Using 2 mm allen wrench, remove
orifice (18,a) from end of nozzle extension.
5. Use wire (or small paper clip) to free any foreign material clogging or
restricting orifice (19,a).
6. Using a garden hose, remove additional debris by back flushing water through
nozzle extension (20). Back flush between 30 to 60 seconds. Turn adjustable nozzle
extension to stream spray and move nozzle from low to high while flushing.
7. Reinstall orifice into nozzle extension. DO NOT overtighten orifice with allen
wrench.
8. Reconnect nozzle extension to spray gun.
9. Make sure garden hose is connected to water inlet. Check that high pressure
hose is connected to spray gun and pump. Turn on water.
10. Start engine following instructions How to Start Your Pressure Washer.
11. Test pressure washer by operating with nozzle in high and low positions.
o-ring Maintenance
Through the normal operation of your pressure washer, o–rings are used to keep
the connections of the hoses and spray gun tight and leak–free. These o-rings may
become worn or damaged.
An O–Ring Maintenance Kit is provided with your pressure washer which includes
replacement o-rings, rubber washer and water inlet filter. Refer to the instruction sheet
provided in the kit to service your unit's o-rings. Note that you will not use all of the
parts in the kit.
To remove a worn or damaged o–ring, use a small flathead screwdriver to get
underneath the o-ring and pry it off.
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.
• NEVER repair leaking connections with sealant of any kind. Replace o-ring or seal.
