Point the gun in a safe direction and discharge excess pressure.Never direct the high-pressure water jet at people or animals.

AUTOMATIC ON/OFF
The pressure washer is equipped with an automatic on/off switch. The pressure washer will only operate when the power switch is in the ON position and the gun trigger is pulled. When you release the trigger to stop spraying water through the gun, the pressure washer motor will automatically shut off. Simply pull the trigger again to continue using the cleaner. To stop using the pressure washer, release the trigger and switch the unit to the OFF position. The unit should be completely shut off when not in use or unattended.

PURGING THE GUN
It is very important to purge the gun before using the pressure washer. Refer to the “Assembly Instructions” to assemble the pressure washer. To purge the gun, simply connect the garden hose to the pressure washer and pull the trigger before turning on the power supply. This allows air trapped inside the pressure washer and gun to be removed before using the unit. Continue to squeeze the trigger for approximately one minute to allow excess air to escape from the unit. During this procedure, water will flow through the gun at low pressure. For additional bleeding tips, refer to the section titled “Operating Instructions”.

GUN SAFETY LOCK
This pressure washer is equipped with a safety lock on the gun trigger. When the pressure washer is not in use, use the safety lock to prevent accidental activation of the high pressure jet.

ADJUSTABLE SPRAY NOZZLE
The adjustable nozzle will allow you to use a variety of spray patterns, from a full fan spray (diagram 1) to a straight stream spray (diagram 2). When using the pressure washer to clean wooden decking, cladding, vehicles etc., always start by using the fan spray and start spraying from a minimum distance of 95cm to avoid damaging the surface of the material you are cleaning. Always start spraying in a test area clear of people and objects.

WARNING : High pressure jets can be dangerous if used incorrectly. The jet must not be directed at people, low voltage electrical equipment or the appliance itself.

UNBLOCK NOZZLE
When the nozzle is clogged, it will cause the pump to build up pressure and may cause the unit to speed up; you can clean the nozzle by inserting the needle into the tip to remove debris. For the adjustable nozzle, you can lubricate the nozzle collar (from high pressure to low pressure) by using non- water soluble grease regularly.

USE OF DETERGENTS

The pressure washer will dispense detergent at low pressure. Use the adjustable spray nozzle to rinse and clean. 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 longer life.

1. STEP 1
   Separate the nozzle from the detergent container by turning the detergent tank counterclockwise and separating the two components.

2. STEP 2
   Fill the detergent container with an approved detergent. Pour the detergent slowly into the tank using a funnel. Re-attach the two components by re- inserting the nozzle into the detergent tank and turn clockwise.

3. STEP 3
   To apply the detergent cleaner to your work area, attach the detergent nozzle to the gun. Turn the pressure washer switch to the ON position. Press the trigger to start the unit. The pressure washer will mix the detergent with water. Do not allow the detergent to dry on the object being cleaned.

WARNING : Never use products containing bleach, chlorine or other corrosive materials, including solvent-based liquids (e.g., gasoline, oils, etc.), trisodium phosphate products, ammonia or acid-based cleaners. These chemicals can cause damage to the unit and the surface being cleaned. Always read the product label first.
