Vibration Hazard:
This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and shoulders. To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an
extended period should first be examined by a
doctor and then have regular medical check-
ups to ensure medical problems are not being
caused or worsened from use. Pregnant women
or people who have impaired blood circulation
to the hand, past hand injuries, nervous system
disorders, diabetes, or Raynaud’s Disease should
not use this tool. If you feel any medical or
physical symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration when there
is a choice between different processes.
5. Include vibration-free periods each day of work.
6. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
Service precautions
Ground Fault circuit interrupter protection
This pressure washer is provided with a ground-fault circuit-interrupter (GFCI) built into the plug of the
power-supply cord. This device provides additional protection from the risk of electric shock. Should replacement
of the plug or cord become necessary, use only identical replacement parts that include GFCI protection.

Operating instructions
read the entire iMpOrtant SaFety inFOrMatiOn section at the beginning of this
manual including all text under subheadings therein before set up or use of this product.
Work piece and Work area Set up
1. Designate a work area that is clean and well-lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
2. CHECK THE WATER SUPPLY. Prior to using
the Pressure Washer for the first time, it is
ESSENTIAL to verify that the water supply is
adequate. The Pressure Washer needs TWICE the
water supply (or volume) of the listed water output
(1.1 GPM). This Pressure Washer will need about
2.2-3 GPM to operate correctly and efficiently. If
the water is being supplied by a well/pump, make
certain that the well/pump produces enough
water to keep up with the Pressure Washer’s
water demands. Water supply hoses should be
heavy-duty. The flow rate of the water supply must
never be allowed to fall below 2.2 GPM.
To determine the water supply’s flow rate:
Run the water at full for 30 seconds into a
5 gallon container, then measure the amount
of water in the container and multiply by 2.
cautiOn! If the Pressure Washer is run
with an inadequate water supply, the pump
may cavitate. Cavitation causes the pump
to operate loudly and will damage it.
3. USE PROPER ELECTRICAL SUPPLY.
This unit uses a large amount of current, especially
during start-up. Turn off power switch, then
connect this unit only to a dedicated household
circuit with no additional loads (running devices)
connected to it. For best results, use the outlet
that is nearest to the circuit breaker panel.
4. PLAN OUT THE JOB Plan out areas to be
cleaned, how many sessions will be necessary,
and how long the individual sessions will need
to be. Plan to clean the higher areas first.
Plan a safe direction for runoff, and plan
on working your way in that direction.
5. Clear the area of all objects that are not being
cleaned. If any water-sensitive or delicate items
cannot be moved, cover them. If detergent is to
be used, cover or remove any plants or animals.
Disconnect power to and protect any nearby
electrical wiring. Close windows and doors.
6. Place the Pressure Washer in a location
which is protected from runoff. The location
should be close enough so that the water
supply hose will reach every portion of the
area with some slack for movement.
7. Route the power cord along a safe route
to reach the work area without creating a
tripping hazard or exposing the power cord
to possible damage. The power cord must
reach the work area with enough extra length
to allow free movement while working.
