Operation
The following cleaning procedure will help you organize your cleaning task and ensure that you achieve
the most beneficial results in the shortest amount of time. Remember to use the spraying/cleaning
techniques previously listed.
1. Surface preparation
It is important to prepare the surface that is to be cleaned. This is done by clearing the area of furniture
and making sure that all windows and doors are closed tight. In addition, you should make sure that all
plants and trees adjacent to the cleaning area are protected by a drop cloth. This will ensure that your
plants won’t be sprayed by the detergents.
2. Initial High Pressure Rinse
The next step is to spray the cleaning surface with water to clear off any dirt or grime that may have
collected on the surface. This will allow your detergent to attack the deep down dirt that has worked its
way into the cleaning surface.
Before triggering the gun, adjust the nozzle to a wide fan pattern and slowly adjust to the desired spray
pattern. This will help you avoid applying too much concentrated spray to the surface which could cause
damage.
TIPS FOR EXTENDING THE LIFE OF YOUR PRESSURE WASHER
1. Never operate the unit without water.
2. This pressure washer is not designed to pump hot water. Never connect it to the hot water supply, this
will significantly reduce the life of the pump.
3. Only use detergents specifically designed for pressure washers. Other types of detergent may cause
internal damage to the unit, as might chemicals such as bleach, washing-up liquid, etc.
4. Never operate the unit for more than one (1) minute without spraying water. Otherwise, the resulting
heat build up will damage the pump.
Winter Storage:
a. For storage during the winter months we recommend the use of a solution of
50/50 mix of antifreeze and water. This will keep the pump from freezing and getting
damaged and will protect the internal components.
b. Method: You will need a length of garden hose and a funnel. Attach the garden
hose to the inlet and pour the antifreeze into the unit via the funnel. Switch the unit
on for a few seconds to allow the solution to flow through the system. Disconnect
your pressure washer from the mains power, and then pack away in your storage
area.
WARNING: Before reusing completely flush the unit out with clean water. Anti-freeze can damage
paintwork so you must ensure there is no antifreeze left in the system before using it again.
