USING THE HIGH PRESSURE HOSE
The high pressure hose features an outer covering that pro-
vides strength to the hose. If the outer covering becomes
damaged, the hose must be replaced immediately. Do not
use a high pressure hose if the outer covering is damaged.
To prevent damage to the outer covering:
 Inspect the hose before every use.
 Fully unwrap and straighten hose before use.
 Do not allow the high pressure hose to be kinked.
 Keep hose away from hot surfaces and sharp edges.
 Do not pull pressure washer by high pressure hose.
 Do not allow hose to be crushed or wrapped around
objects.
USING THE PRESSURE REGULATOR KNOB
See Figure 21.
Use the pressure regulator knob to adjust the amount of
pressure being delivered through the high pressure hose.
 To increase pressure, rotate knob clockwise.
 To decrease pressure, rotate knob counterclockwise.
WASHING WITH DETERGENT
See Figures 22 - 23.
As sold, this pressure washer is designed for use with "down-
stream" pressure washer detergents. To convert for use with
"upstream" detergents, contact an authorized customer
service center for more information.
Use only detergents designed for pressure washers; house-
hold detergents, acids, alkalines, bleaches, solvents,
flammable material, or industrial grade solutions can
damage the pump. Many detergents may require mixing
prior to use. Prepare cleaning solution as instructed on the
solution bottle.
