PW40SOH QUICK SETUP GUIDE
WARNING Failure to read and follow the operator’s manual and all operating instructions could result in death, serious
injury, and/or property damage.
WARNING Fuel and its vapors are extremely flammable and explosive which could cause burns, fire or explosion resulting
in death or serious injury. Turn pressure washer engine OFF and let it cool at least 2 minutes before removing fuel cap. Let
spilled fuel evaporate before starting engine. Always allow space for fuel expansion.
WARNING Starter cord kickback (rapid retraction) will pull hand and arm toward engine faster than you can let go which
could cause broken bones, fractures, bruises, or sprains resulting in serious injury. NEVER pull starter cord without first
relieving spray gun pressure. Pull starter cord slowly until resistance is felt, then pull rapidly. Firmly grasp spray gun with
both hands when using high pressure spray to avoid injury when spray gun kicks back.
WARNING Engine exhaust contains carbon monoxide, a poisonous gas that could kill you in minutes. You CANNOT smell
it, see it, or taste it. Operate ONLY outside far away from windows, doors and vents. Install carbon monoxide alarms. DO
NOT run this product inside homes or garages, even if using fans or opening doors and windows.
WARNING High water pressure could cut through skin resulting in serious injury. Spray gun traps high water pressure,
even when engine is stopped and water is disconnected. NEVER aim spray gun at people, animals, or plants. ALWAYS
point spray gun in safe direction, press red button and squeeze spray gun trigger to release high pressure, every time you
stop engine.
WARNING Risk of eye injury. Spray could splash back or propel objects resulting in serious injury. Always wear indirect
vented (chemical splash) safety goggles marked to comply with ANSI Z87.1 when using or in vicinity of this equipment.
NEVER substitute safety glasses or dry-condition goggles for indirect vented safety goggles.

PW40SOH QUICK SETUP GUIDE
ASSEMBLE PRESSURE WASHER
1. Place handle (A) onto handle supports (B) connected to main unit. Make sure holes
(C) in handle align with holes (C) on handle supports. (See Fig. 1)
NOTE: It may be necessary to move the handle supports from side to side in order to
align the handle so it will slide over the handle supports.
2. Insert carriage bolts (D) through holes from outside of unit and attach a plastic knob
(E) from inside of unit. Tighten by hand. (See Fig. 2)
ADD ENGINE OIL AND FUEL
NOTE: You MUST properly fill engine with oil before attempting to start pressure
washer.
DO NOT use E85 fuel.
DO NOT mix oil with fuel.
1. Move pressure washer outdoors to a flat, level surface.
2. Clean area around oil fill and remove oil fill cap/dipstick. (See Fig. 3)
3. Using oil funnel (optional), slowly pour contents of provided oil bottles into oil fill
opening to the point of overflowing.
4. Replace oil fill cap/dipstick and fully tighten.
5. Clean area around the fuel cap. (See Fig. 4)
6. Remove fuel cap and add clean, fresh, UNLEADED fuel. Be careful not to overfill.
Allow about 1 in. of tank space (F) for fuel expansion, as shown. (See Fig. 5)
7. Replace fuel cap and let any spilled fuel evaporate before starting engine.
MOVE PRESSURE WASHER TO SAFE OPERATING LOCATION
1. Move pressure washer outdoors to a flat, level surface. Running engines give off
carbon monoxide.
2. Keep at least 5 ft. (1.5 m) clearance on all sides of pressure washer including
overhead to reduce the risk of exhaust heat or exhaust gases igniting nearby
combustible material.
WARNING Engine exhaust contains carbon monoxide, a poisonous gas that could kill you
in minutes. You CANNOT smell it, see it, or taste it. Operate ONLY outside far away from
windows, doors and vents. Install carbon monoxide alarms. DO NOT run this product
inside homes or garages, even if using fans or opening doors and windows.
CONNECT SPRAY GUN
NOTE: Remove and discard the shipping caps from the pump’s high-pressure outlet
and water inlet before attaching hoses.
1. Uncoil high-pressure hose (G) attach quick-connect end of hose to base of spray
gun (H). Pull down on collar of quick-connect, slide onto spray gun and let go of
collar. Tug on hose to be sure of tight connection. (See Fig. 7)
2. Similarly, attach other end of high-pressure hose (G) to high-pressure outlet (J) on
pump. Pull down on collar of quick-connect, slide onto pump and let go of collar.
Pull on hose to be sure of tight connection. (See Fig. 8)
