Instructions for Installation/Set-up, Operation, Maintenance, & storage
This pressure washer produces hot-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.
• 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.
• 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. Always keep a fire extinguisher rated "ABC" nearby.
• 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/Installation" section
for where to report missing or damaged parts.
Add Engine Oil: Engine is shipped without oil. See the "Engine Manual" section of this manual for instructions on
capacity and viscosity recommendations.
Water Flow Requirements: Make sure your supply water flow rate is 20% higher than the pressure washer's flow rate
(see "Operations", 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.
Storage: Do not allow water to freeze in the pump, hose, or spray gun(s). See "Storage" for more information.
Maintenance Schedule: Engine and pump require periodic inspection and servicing to keep pressure washer
functioning efficiently. See "Maintenance Schedule Summary" for frequency of servicing.
