Cold Water, Belt Drive Pressure Washer
Instructions for Installation/Set-up, Operation, Maintenance, & Storage
This pressure washer produces cold water high pressure spray. Cleaning chemicals may be incorporated into the
spray if desired. The pressure pump for this equipment is powered by a gasoline internal combustion engine.
WARNING: SPECIAL HAZARDS
CO Poisoning: Exhaust from engine contains carbon monoxide, a poisonous gas that can cause carbon monoxide
poisoning and possible death if inhaled. ONLY run pressure washer OUTDOORS and at least 20 feet from the home, away
from windows, vents and air intakes, to allow proper ventilation. 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.
Injection Injury: High-pressure spray can pierce skin and underlying tissues, leading to serious injury and possible
amputation. Such an injection injury can result in blood poisoning and/or severe tissue damage.
Flying Debris: High-pressure spray can cause flying debris and possible surface damage.
Slips/Falls: Spray discharge can cause puddles and slippery surfaces. Spray-gun kickback can cause operator loss of
balance and falls.
Electric shock: Operating equipment in wet conditions or near water can cause electric shock.
Chemical Exposure: Cleaning chemical vapors or contact with skin may be hazardous.
Fire/Explosion: Engine sparking can ignite fuel or other flammable liquids or vapors in the vicinity. Hot exhaust from engine
can ignite combustible materials.
Burns: Pressure Washer pump and engine are hot surfaces that can cause burn injuries.
Detailed safety information about these hazards appears throughout this manual.
Inspect Upon Delivery: FIRST! Inspect for missing or damaged components. See “Initial Set-Up” section for where
to report missing or damaged parts.
Add Engine Oil: Engine is shipped without oil. See engine manual for instructions on capacity and viscosity
recommendations.
Replace Temporary Pump Oil Plug: Pump is shipped with oil but with a temporary shipping plug. Check pump oil
level before starting and replace temporary shipping plug with permanent oil fill plug provided within plastic bag
containing this Owner’s Manual.
Battery Required: A battery is not included. A battery must be installed before starting the engine or damage to the
engine voltage regulator will result. Purchase a standard 12 VDC, 18 Ah lawn and garden battery (Group U1-7).
Water Flow Requirements: Make sure your supply water flow rate is 20% higher than the pressure washer's flow
rate (see "Specifications" section for detail), and that your water is clean and particle free.
Chemical Spraying: Use only approved pressure washer chemicals designed for high-pressure use. Use chemical
adjustment knob to regulate cleaning power (on select units).
Storage: Do not allow water to freeze in the pump, hose, or spray gun(s). See “Storage” for more information.
Maintenance Schedule: Engine, pump, and belts require periodic inspection and servicing to keep pressure washer
functioning efficiently. See “Maintenance Schedule Summary” for frequency of servicing.
