IMPORTANT OPERATION / MAINTENANCE PRECAUTIONS
!
Change oil in pump after the first 50 hours, then every 500 hours.
Use SAE30 Non-Detergent Motor oil.
!
"
Change engine oil as specified by the Honda. See Honda owners manual.
Do Not run washer longer than 3 minutes with gun closed, as this can result in damage to the
seals. Heat generated by the re-circulating water can damage seals.
Avoid freezing pump. Drain unit prior to storage, or run an antifreeze solution through pump.
Ensure the pump and hoses are completely bleed of all liquid.
"
START-UP AND OPERATION INTRODUCTION
1. Verify that the vented YELLOW dip stick is installed in
pressure washer pump. Remove the RED shipping plug
( if present ) from top of the pump and replace it with the
YELLOW oil level dipstick provided. Fig. 1
Yellow
Red
2. Before first use, check engine and pump oil levels.
Note: For shipping purposes, engine oil has not been
added.
Fig. 1
Before each use, check engine oil level by unscrewing
the oil dipstick. Add motor oil (consult Honda manual
for correct grade) as required to bring to proper level,
approximately mid-way on dipstick.
3. Check water supply volume. To operate correctly, the unit
requires a water supply 25% greater than the units output.
( i.e. PW2700SC = 3 GPM, PW2000SC = 3.75 GPM of
water flow).
To test water supply output;
Fig. 2
a) Turn water flow to full maximum output.
b) Place a 5 gallon pail or container under water flow for
exactly 1 minute ( 60 seconds).
Pressure
Control
c) Measure contents to determine water flow.
4. Connect a standard garden hose to the water inlet or
bottom connection on the pump head ( Female hose
connector ). Fig. 2.
5. Connect the high pressure hose to the water “Outlet”
or upper connection on the pump head.
( Male quick connect nipple). Fig. 2.
6. Turn the unloader knob on top of the pump head counter-
clockwise to reduce the pressure prior to starting the
machine.
7. Select the desired tip for the job. Insert tip into wand

Unloader Service
The unloader is made up of may
small o-rings, springs and check
balls. Repair kits are available to
replace these “Soft Goods”.
Repairs requiring the
replacement of valve bodies or
“Hard Goods” may be more
economically solved through the
replacement of the entire “Bolt
On” unloader. Shop labor may
make an unloader repair a poor
economical choice.

PUMP SERVICE
All inlet and discharge valves can be serviced without disrupting the inlet or discharge plumbing. The
inlet and discharge valves are identical on all H.E.R.O. models. See pages 8-10 and 14-16.
VALVE ASSEMBLIES
1. To service any valve, remove valve cap ( ref # 10 ) and extract valve assembly ( ref # 4-A-D-9 ).
2. Examine o-rings and replace if there is any evidence of cuts, abrasions or distortion.
3. Remove valve assembly ( ref # A-D ) from valve cavity.
4. Remove o-ring ( ref # 4 ) from valve cavity.
5. Only one valve kit is necessary to repair all the valves in the pump. The kit includes new o-rings,
valve seat, poppet, spring and retainer, ( ref # 4, A-D ) all pre-assembled.
6. Install new o-ring in valve cavity.
7. Insert assembly into valve cavity.
8. Replace valve cap ( ref # 10 ) and torque to 74 foot pounds.
