3. ALWAYS point spray gun in a safe direction, press red button and squeeze trigger to release retained high water pressure.
IMPORTANT: Spray gun traps high water pressure, even when engine is stopped and water is disconnected.
12. Using Nozzles
12.1 Attaching Pressure Nozzles to Spray Wand
1. Engage trigger lock on spray gun.
2. Pull slip ring on female quick-disconnect fitting of spray wand back.
3. Insert nozzle into female quick-disconnect socket on spray wand.
4. Release slip ring on female quick-disconnect and twist. Listen for “lick” to
ensure both quick-disconnects are coupled.
4. Pull high pressure nozzle and spray wand in opposite direction to ensure they
do not separate.
12.2 Nozzle Size Guide
The pressure washer comes with five spray nozzles. Each nozzle is color coded and delivers a specific spray pattern and pressure
for a particular cleaning job. The size of the nozzle determines the size of the fan spray and the pressure out of the nozzle.
The are stored in receptacles on a panel mounted to the handle of the washer. Colors on the panel identify nozzle location and
spray panel.
0°Nozzle - Red: This nozzle delivers a pinpoint stream of pressurized water and is
extremely powerful. It covers only a small area of cleaning. This nozzle should only
be directed at surfaces that can withstand high pressure such as metal or concrete.
Do not use this nozzle to clean wood.
15°Nozzle - Yellow: This nozzle delivers a powerful 15 degree spray pattern for
intense cleaning of small areas. This nozzle should only be used on areas and
materials that can withstand high pressure.
25° Nozzle - Green: This nozzle delivers a 25 degree spray pattern for intense
cleaning of larger areas. This nozzle should only be used on areas that can
withstand pressure from this nozzle.
40°Nozzle - White: This nozzle delivers a 40 degree spray pattern and a less powerful
stream of water. This nozzle can cover a wide area and should be used for most
general cleaning jobs.
Chemical Nozzle - Black: This nozzle is used to apply special chemicals and cleaning
solutions. This nozzle produces the weakest pressure stream of the five nozzles.
•Pressure washer produces fluid pressures and velocities high enough to penetrate
human and animal flesh which could result in serious injury or amputation.
•Do not point pressure washer in direction of people or animals.
•High velocity fluid spray can cause objects to break, propelling particles at high
speeds..

13. Adjusting Spray Pressure
Pressure Rinsing
1. Remove black spray tip from nozzle extension.
2. Select and install desired high pressure spray tip.
3. Keep spray gun a safe distance from area you plan to spray.
4. Increase (decrease) spray pressure by turning pressure control knob
clockwise (counterclockwise).
5. Apply a high pressure spray to a small area and then check surface for
damage. If no damage is found, you can assume it is okay to continue
rinsing.
6. Start at top of area to be rinsed, working down with same overlapping
strokes as you used for cleaning.
14. Using Chemicals & Detergents
NOTE: Use only detergents designed for pressure washers; household detergents, acids, alkalines, bleaches, solvents,
flammable material, or industrial grade solutions can damage the pump. Many detergents may require mixing prior to use.
Prepare cleaning solution as instructed on the solution bottle.
14.1 Set Up Procedure:
1. Attach the chemical hose onto the barbed fitting situated near the back of
the high pressure hose connection.
2. Press the other end of the chemical hose (with the filter attached) into the
container holding the chemicals or detergents you are using.
3. Attach the chemical nozzle onto the lance as shown previously.
14.2 Chemical Cleaning
1. Spray the chemicals onto a dry surface using the procedures outlined in
previous sections. Start at the lower portion of the cleaning area and
working upwards, using long, even, overlapping strokes.
2. Always ensure that the filter is fully submerged in the cleaning solution at
all times.
3. Allow the detergent to soak in for 3-5 minutes before washing and rinsing.
4. Re-apply as needed to prevent the surface from drying. Do not allow the
detergent to dry on to the cleaning surface to prevent streaking.
NOTE: Detergent cannot be applied with the high pressure spray tips (white,
green, yellow or red)
14.3 After Chemical Cleaning
IMPORTANT: You will need to flush the detergent siphoning system after each
use by placing the filter into a bucket of clean water then run the pressure
washer in low pressure for 1 -2 minutes.
1. After using chemicals, soaps and detergents it is necessary to thoroughly clean the pressure washer.
2. Place the chemical hose in a container of clean water.
3. Turn on the pressure washer and hold the trigger on the spray gun top draw clean water through the system to clean it
thoroughly.

15. Maintenance
To ensure efficient operation and longer life of your pressure washer a routine maintenance schedule should be prepared and
followed. If the equipment is used in unusual conditions such as high-temperature or dusty conditions more frequent maintenance
checks will be required.
15.1 Engine:
Check the engine regularly, replace oil, clean spark plugs and maintain parts as required.
15.2 Pump Oil:
Change the pump oil regularly. Change the pump oil after the first 50 hours of work and successively every 200 hours.
In either case ensure that the oil is changed at least once a year. Check with your nearest Dealer for advice on the best Pump Oil
to use with this equipment if you are unsure.
15.3 Nozzle Unclogging:
If the nozzle becomes clogged with dirt and debris excessive pressure can build up. If the nozzle becomes partially clogged or
restricted the pump pressure will fluctuate and can become harmful and dangerous.
Clean the nozzle immediately and follow these instructions:
1. Shut-off the engine and turn off / disconnect the water supply.
2. Pull the trigger on the gun to relieve any water pressure.
3. Disconnect the lance from the gun.
4. Remove the nozzle from the lance - remove any obstructions
with the nozzle cleaning tool and back flush with clean water.
5. Direct the water supply into the spray wand end to back flush
loosened particles for 30 seconds.
6. Reassemble the nozzle onto the lance.
7. Reconnect the lance to the gun and turn on the water supply.
8. Start the washer pump and place the lance into the high
pressure setting to test.
15.4 Cleaning The Water Filter:
The water filter should be checked regularly and cleaned if necessary:
1. Remove the filter by grasping the end and removing it from the water
inlet on the pump.
2. Clean the filter by flushing it with water on both sides.
3. Re-insert the filter in the water inlet on the pump.
Before performing any maintenance be aware that the equipment should be completely shutdown,
depressurized and allowed to cool down. This will ensure that no injuries can be sustained by moving parts,
water pressure or hot surfaces.
Engine contains flammable fuel do not smoke near or work near naked flames while maintaining this
equipment. Please note: All repairs should be carried out by Dealer approved engineers. All replacement
parts should be supplied or recommended by the Dealer. Any unapproved repairs or modifications will
invalidate the warranty.
Avoid prolonged or repeated skin
contact with used motor oil.
