IMPORTANT SAFETY INSTRUCTIONS
This manual has important information for the use and safe operation of this
machine. Read thoroughly and understand all warnings before using.
 Read all the instructions before using machine
 To reduce risk of injury, close supervision is necessary when the machine is used near
children. Do not allow children to operate pressure washer at any time.
 Know how to stop the machine and bleed pressure quickly.
 Keep operating area clear of all persons.
 Follow the maintenance instructions specified in the manual.
 Operate this unit in a well ventilated area.
 Wear protective eye wear & clothing when operating.
 Do not operate the machine when fatigued or under the influence of alcohol or drugs.
 Do not overreach or stand on unstable support. Keep good footing and balance at all times.
 To prevent fire hazard, do not use with or near inflammables such as gasoline, grain dust,
solvents and thinners. Do not spray flammable liquids.
 Never add gasoline to a hot engine as this can result in a fire or explosion. Allow engine to
cool before refueling.
 Never direct spray at pressure washer unit.
 Keep water spray away from any electrical wiring.
**WARNING**
Risk of injection or injury.
Do not direct discharge stream at people.
The high pressure water stream can cause injury or death!
IMPORTANT OPERATION / MAINTENANCE INSTRUCTIONS
 Change oil in pump after the first 50 hours, then every 500 hours.
Use 30W Non-Detergent Hydraulic oil.
Available from Hero Industries, Part # PW-5015
 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 bled of all liquid.

1.Verify that the vented YELLOW dip stick is installed in the
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 Pump oil should
be visible half way up sight glass. Use 30W non-detergent
hydraulic oil.
2.Before first use, check engine and pump oil levels.
For shipping purposes, engine oil has not been added.
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.
Model APS2500 = 4 GPM (gallons per minute), of water flow).
Damage to the pump will occur if there is not enough volume.
To check the water supply volume, obtain a empty 5 gallon
container and record the time it takes to fill the container. It
should be within the required GPM, if it is not then you should
find another water supply.
4.Connect a minimum 5/8” diameter garden hose to the water
inlet or bottom connection on the pump head (Female hose
connector). Fig. 4
5.Connect the high pressure hose to the water “Outlet”or upper
connection on the pump head. (Male quick connect nipple) as
shown in Fig. 5.
6.Turn the unloader knob on top of the pump head counter
clockwise to reduce the pressure prior to starting the engine.
7.Remove high pressure nozzle from quick coupler & open gun.
This will allow pump to be fully primed before starting engine.
8.Turn on the water supply and make sure that there is no leaks
in water supply hose.
9.Trigger the spray gun to purge all air from the system, PRIOR
to starting engine.
10.Start the engine by following this procedure:
a) - Turn the ON/OFF switch to ON.
b) - Turn the GAS to ON.
c) - Turn the CHOKE to FULL.
d) - Push the THROTTLE lever to the ON position.
e) - Pull the STARTING cord. Gun should be held open ,with
water flowing freely while pulling starting cord.
f) - Once the engine has started, reduce the CHOKE until it is
OFF, and open the THROTTLE to full ON. It is now safe to
release trigger to the off position. Use these instructions in
conjunction with instructions provided in the Honda manual.

START-UP AND OPERATION INTRODUCTION
Chemical and Soap Spray
To introduce chemicals/detergent to the spray,
1. Turn unit off.
2. Trigger gun to relieve all internal fluid pressure.
3. Attach chemical injector to unit if using a quick disconnect injector.
4. Open the chemical injector knob by turning it counter clockwise.
5. Connect the chemical injector line to the chemical injector.
6. Place the suction line filter end into the chemical / detergent jug. Use
only detergent designed for use with pressure washers. Only use
chemicals/detergents in well ventilated areas.
1. Install “Black” injector tip into gun. VERY IMPORTANT. The injector will
only dispense detergent with the BLACK nozzle.
2. Re-start pump and set pressure to low.
3. Apply detergent to work surface. Do not allow detergents to dry on any
surface.
Injector siphoning is best at very low pressure. Once the injector
material stream has been established, the pump operating pressure
can be increased. Remember to flush injector with clean water after
use.
Install Soap (Black) Nozzle

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 a
poor economical choice.
