Operation
Avoid inhalation of exhaust. Running this pressure
washer indoors can kill you in minutes. Exhaust contains
carbon monoxide. This is a poison you cannot see or
smell.
Never pull by hose. Do not move this pressure washer
by pulling on the hose. Hose or connections could fail
and result in catastrophic high-pressure release of fluid
as well as hose whipping.
Avoid sharp objects. Keep hose away from sharp
objects. Bursting hoses may cause injury.
No load bearing. Do not use the pump to support other
items of equipment that impose unacceptable loads on
the pump. Do not attempt to use this pressure washer
as a prop.
Lock trigger safety latch when not spraying. Spray
gun is equipped with a built-in trigger safety latch to
guard against accidental trigger release. Rotate safety
latch to the locked position when not spraying.
Leaving unattended. Always turn off the pressure
washer and relieve system pressure before leaving the
sprayer unattended.
Prompt Emergency Response
Seek medical aid for suspected injection injury. If
injured by high-pressure fluid, no matter how small the
wound is, see a doctor at once. A typical injection injury
may be a small puncture wound that does not look
serious. However, severe infection or reaction can
result if proper medical treatment is not administered
immediately by a doctor who is familiar with injection
injuries.
Seek medical aid for suspected carbon monoxide
poisoning. The running engine gives off carbon
monoxide, a poisonous gas that can kill you. If you start
to feel sick, dizzy, or weak while using the pressure
washer, shut off the engine and get to fresh air RIGHT
AWAY. See a doctor. You may have carbon monoxide
poisoning.
Wear Personal Protective Gear
WARNING
Wear personal protective gear to prevent:
- Eye and skin injection injury from high pressure spray
- Eye injury from flying debris
1. Wear waterproof gloves, ANSI Z87.1 compliant
safety goggles, face protection, and protective
clothing when operating the pressure washer.
If spraying pressure washer specific chemicals, wear
a respirator mask to avoid inhalation of vapors if
directed on the chemical label.
2. Wear non-slip, protective footwear. Use of pressure
washer can create puddles and slippery surfaces.
Wear footwear capable of maintaining a good grip on
wet surfaces.
Preparing for Operation
Make sure that any regular maintenance has been
performed as prescribed in “Maintenance & Repair”
section.
