SPECIFIC SAFETY RULES
■ Make sure your extension cord is in good condition. When using an extension cord, be sure to
use one heavy enough to carry the current your product will draw. A wire gauge size (A.W.G.) of
at least 14 is recommended for an extension cord 25 feet or less in length. If in doubt, use the next
heavier gauge. The smaller the gauge number, the heavier the cord. An undersized cord will cause
a drop in line voltage resulting in loss of power and overheating.
■ Inspect extension cords periodically and replace if damaged. Keep handles dry, clean, and free
from oil or grease.
■ Never direct a water stream toward people or pets, or any electrical device.
■ Before starting any cleaning operation, close doors and windows. Clear the area to be cleaned
of debris, toys, outdoor furniture, or other objects that could create a hazard.

animals, electrical devices, or the machine itself.
■ Keep the motor away from flammables and other hazardous materials.
■ Check bolts and nuts fixing the pressure washer shell for looseness before each use. A loose
bolt or nut may cause serious motor problems.
■ Before storing, allow the motor to cool.
■ When servicing use only identical replacement parts. Use of any other parts may create a
hazard or cause product damage.
■ ONLY use cold water.
■ Make sure minimum clearance of 3 feet is maintained from combustible materials.
■ Connect pressure washer only to an individual branch circuit.
■ Hold the handle and wand securely with both hands. Expect the trigger handle to move when
the trigger is pulled due to reaction forces. Failure to do so could cause loss of control and injury to
yourself and others.
