HOW TO USE DETERGENTS
Detergents are not required when using the pressure washer. However, some stubborn jobs may need detergent.
THE PRESSURE WASHER CAN DISPENSE DETERGENT AT A LOW PRESSURE. BIODEGRADABLE
DETERGENTS ARE SPECIFICALLY FORMULATED TO PROTECT THE ENVIRONMENT AND YOUR PRESSURE
WASHER. THESE DETERGENTS WILL NOT CLOG THE FILTER AND WILL PROTECT THE INTERNAL PARTS OF
THE PRESSURE WASHER FOR A LONGER LIFE.
Step 1
Separate the nozzle from the detergent container by turning the detergent reservoir counter clockwise and separating
the two components.
Step 2
Fill the detergent container with approved detergent. Pour the detergent slowly into the reservoir using a funnel.
Reattach the two components by reinserting the nozzle back onto the detergent reservoir and turning clockwise.
USE OF EXTENSION CORDS
Use of an extension cord with this product is NOT RECOMMENDED. If you must use an extension cord, use only
extension cords that are intended for outdoor use. These cords are identified by a marking “ACCEPTABLE FOR USE
WITH OUTDOOR APPLIANCES, STORE INDOORS WHILE NOT IN USE.” Use only extension cords having an
electrical rating not less than the rating of the product. Examine the extension cord before use. DO NOT USE
DAMAGED EXTENSION CORDS! Do not pull on cord to disconnect from receptacle, always disconnect by
pulling on plug. Keep cord away from heat and sharp edges. Always disconnect the extension cord from the
receptacle before disconnecting the product from the extension cord.
OPERATING INSTRUCTIONS
USE WITH COLD WATER ONLY! DO NOT USE HOT WATER IN THIS PRESSURE WASHER!
TO START
After connecting the pressure washer to the cold water supply, proceed as follows:
Make sure that the POWER switch is in the OFF position.
Make sure the unit has been assembled:
Connect the garden hose to the inlet fitting.
Insert the adjustable spray nozzle into the gun.
Connect the high pressure hose to the high pressure outlet fitting.
Connect the high pressure hose to the gun.
Connect the gun to the specified detergent nozzle.
Open the water supply valve completely.
Before turning the unit on, press the gun trigger to bleed all the remaining air out of the pump and hose.
Start the pressure washer by turning the power switch to the on position and squeeze the trigger.
REMINDER: Motor does not run continuously, only when the trigger is squeezed.
WARNING - RISK OF INJURY! Unit will start spraying when trigger is squeezed. When turning the unit off after use,
high pressure still exists inside the hose and unit. Point the gun in a safe direction and discharge the excess pressure.
NEVER direct the high pressure water stream at people or animals.

Automatic On/Off
The pressure washer is equipped with an automatic on/off switch. The unit will only run when the power switch is in
the ON position and the trigger on the gun is squeezed. When you release the trigger to stop spraying water through
the gun, the motor on the pressure washer will automatically shut off. Simply squeeze the trigger again to resume
using the cleaner. To stop using the pressure washer, release the trigger and switch the unit to the OFF position. The
unit should be turned completely OFF while not in use.
Bleeding The Gun
It is very important to bleed the gun before using the pressure cleaner. To bleed the gun, connect the garden hose to
the pressure cleaner and squeeze the trigger BEFORE turning the electrical supply on. This allows any air trapped
inside the pressure cleaner and gun to be removed before using the unit. Continue holding trigger for approximately
one minute to allow any excess air out of the unit. Water will flow through the gun at low pressure during this
procedure.
CLEANING TIPS
WARNING: ALWAYS TEST THE SPRAY IN AN AREA FREE AND CLEAR OF PEOPLE AND OBJECTS BEFORE
YOU SPRAY AT THE INTENDED CLEANING SURFACE.
Wood and Vinyl Decks
Rinse deck and surrounding area with fresh water. If using detergent, fill the detergent reservoir and apply to the area
being cleaned at low pressure. For optimal results, reduce your work area to smaller sections and clean each section
one at a time. Allow the detergent to rest on the surface for a few minutes and then rinse at high pressure. DO NOT
LET THE CLEANSER DRY.
Always clean from left to right and top to bottom for best results. Rinse at high pressure using the fan spray keeping
the tip of the spray nozzle at least 6-9 inches from the cleaning surface.
Maintain a further distance from the cleaning area when using a direct spray. CAUTION: For softer woods, increase
the distance from the cleaning area.
Cement Patios, Stone, and Brick
Rinse cleaning and surrounding area with fresh water. If using detergent, fill the detergent reservoir and apply to the
area being cleaned at low pressure. Rinse at high pressure using the fan spray in a sweeping motion keeping the tip
of the spray nozzle at least 3-6 Inches from the cleaning surface. Maintain a further distance from the cleaning area
when using a direct spray.
Cars, Boats, and Motorcycles
Rinse cleaning and surrounding area with fresh water. If using detergent, fill the detergent reservoir and apply to the
area being cleaned at low pressure. To achieve the best results, clean one side at a time. Allow the detergent to rest
on the surface for a few minutes, but do not let the detergent dry. Rinse at high pressure using the fan spray in a
sweeping motion keeping the tip of the spray nozzle at least 8 inches from the cleaning surface. Maintain a further
distance from the cleaning area when using a direct spray. Wipe surface dry for a polished finish.
Barbecue Grills, Power Equipment, and Garden Tools
Rinse cleaning and surrounding area with fresh water. If using detergent, fill the detergent reservoir and apply to the
area being cleaned at low pressure. Allow the detergent to rest on the surface for a few minutes, but do not let the
detergent dry. Rinse at high pressure using the fan spray keeping the tip of the spray nozzle at least 1-3 inches from
the cleaning surface. Maintain a further distance from the cleaning area when using a direct spray.

WARNING
To reduce the risk of injury, never direct a water stream towards people or pets or place any body part in the stream.
Do not hold hoses or fittings.
To reduce the risk of injury from kickback, hold the spray wand securely with both hands when the machine is on.
Failure to use in dry conditions and to observe safe practices can result in electric shock.
PROPER USE OF THE PRESSURE WASHER
ONLY USE COLD WATER WITH THE PRESSURE WASHER! DO NOT USE HOT WATER!
Operate the pressure washer at no more than the fluid pressure rated for the pressure cleaner.
DO NOT run the pressure washer without a water supply. Running the unit without a water supply will cause damage
to the unit. Make sure that the water supply is clean and not dirty.
CAUTION
Test the spray in a clear area before use. High-pressure water flow can damage any surface if not used properly!
DO NOT move the unit by pulling on the high pressure hose.
DO use the carry handle which is located on the top of the unit.
Use two hands when holding the high pressure gun and wand.
Keep one hand on the gun/trimmer, hold the wand with the other hand.
The pressure washer applies detergent to the cleaning area at low pressure only. When the detergent has been
applied, spray the detergent off of the work area by using the adjustable nozzle.
Gun Safety Lock
A gun trigger safety lock is built into wand. Be certain to use the safety lock when not using the pressure washer.
Adjustable Spray Nozzle
Always begin by spraying in a test area free and clear of people and objects. You can use a variety of spray patterns,
from a full fan spray to a direct stream spray. Begin by using the fan spray, then stand a minimum distance 36" away
to avoid damaging the surface of the material you are cleaning. Warning: High pressure jets can be dangerous. DO
NOT direct the jet stream at persons, live electrical equipment or the appliance itself. Wear protective footwear and
clothing. Do not direct the jet against yourself or others in order to clean clothes or footwear.
Detergent Nozzle
Use the detergent nozzle to apply liquid detergent onto the work surface. Fill the container with detergent only. Do not
put water into the container. The pressure cleaner will mix water and detergent automatically. When finished applying
the detergent to the work surface, insert the adjustable spray nozzle, and remove the detergent by using the high
pressure spray.
