1. Surface Preparation

The following cleaning procedure will
help you organize your cleaning task
and ensures that you will achieve the
best results in the shortest amount of
time. Remember to use the spraying /
cleaning techniques mentioned in the
following section.
Before starting a pressure washer
cleaning job, prepare the surface you
intend to clean. Clear furniture from
the area and make sure that all
windows and doors are closed tightly.
Also, protect all plants and trees near
the cleaning area with a drop cloth. A
covering ensures that your plants won't
be sprayed by the detergents.
2. Start Up
ALWAYS use this start up procedure to
ensure that the unit is started safely and
properly.
If water has frozen
in the pressure
washer, thaw the pressure washer in a
warm room before starting. DO NOT
pour hot water on or into the pump;
internal parts will be damaged.
