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 an electric motor.
• 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: Motor sparking can ignite fuel or other flammable liquids or vapors in the vicinity.
• Burns: Pressure washer pump and motor 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.
Pump: Pump is shipped with oil. Check pump oil level before starting. Remove shipping plug and install vented fill
cap.
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. Maximum inlet water temp.
180˚F (82˚C) for 1571107 and 185˚F (85˚C) for 1571108 & 1571109.
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: Motor and pump require periodic inspection and servicing to keep pressure washer
functioning efficiently. See "Maintenance Schedule Summary" for frequency of servicing.
