Operation
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.
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.
1. Ensure that the power switch is in the “OFF” position.
2. Attach swivel adapter to pump water inlet, if not already attached. Notice the
swivel adapter is marked with the words pump and hose. Make sure to connect
pump side of adapter to pump water inlet to prevent damage to the threads.
3. Attach a garden hose to the inlet side of the pump and connect it to the water
supply. Use a hose with an internal diameter (I.D.) of 5/8 in. (1.58 cm) and a length
of 50 ft. (15 m) or less.
Some local plumbing codes require backflow prevention when
connecting to a fresh water supply. Install a backflow preventer upstream
from the pump if necessary.
a. If inlet water pressure is over 100 psi, install a regulating water valve at the
garden hose connection.
b. Do not exceed 100˚ F (38˚ C) inlet water temperature.
NOTE: The inlet water supply must have a minimum flow rate of 5 gpm (19 lpm).
