READ AND UNDERSTAND ALL WARNINGS BEFORE STARTING UNIT

When using the high pressure setting, DO NOT

allow the

high pressure spray to come in contact with unprotected skin,

eyes, or with any pets or animals. Serious injury can occur.
Your washer operates at fluid pressures and velocities high enough to penetrate
human and animal flesh, which could result in amputation or other serious injury.
Leaks caused by loose fittings or worn or damaged hoses can result in injection
injuries. 

DO NOT TREAT FLUID INJECTION AS A SIMPLE CUT! See a

physician immediately!

NEVER

fill fuel tank when engine is running or hot. Do not

smoke when filling fuel tank.

NEVER

fill fuel tank completely. Fill tank to 1/2" below bottom of filler neck to

provide space for fuel expansion. Wipe any fuel spillage from engine and
equipment before starting engine.

NEVER

run engine indoors or in enclosed, poorly ventilated areas. Engine

exhaust contains carbon monoxide, an odorless and deadly gas.

DO NOT

let hoses come in contact with very hot engine muffler during or

immediately after use of your pressure washer. Damage to hoses from contact
with hot engine surfaces will NOT be covered by warranty.

NEVER

pull water supply hose to move pressure washer. This

could damage hose and/or pump inlet.

DO NOT

use hot water, use cold water only.

NEVER

turn water supply off while pressure washer engine is running or

damage to pump will result.

DO NOT

stop spraying water for more than two minutes at a time. Pump

operates in bypass mode when spray gun trigger is not pressed. If pump is left
in bypass mode for more than two minutes internal components of the pump
can be damaged.

If you do not understand these precautions, please call 1-800-888-2468 to
speak to a service representative for further instructions.

The high pressure spray from your pressure washer is capable of
causing damage to surfaces such as wood, glass, automobile paint,

auto striping and trim, and delicate objects such as flowers and shrubs. Before spraying,
check the item to be cleaned to assure yourself that it is strong enough to resist damage
from the force of the spray.
