Owner’s Manual 

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. 

Equipment Protection Quick Facts 

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.
