The spark arrester must be serviced every 50 hours to keep it
functioning as designed.
If the engine has been running, the muffler will be very hot.
Allow the muffler to cool before servicing spark arrester.
•
Remove spark arrester screen for cleaning and
inspection.
•
Replace if screen is damaged.
Air Cooling System
Over time debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have an authorized Sears
service dealer clean the cooling system per recommended
intervals (see “Maintenance Schedule” on page 16). Equally
important is to keep top of engine free from debris. See “Clean
Debris”.
Clean Combustion Chamber
We recommend you have an authorized Sears service dealer
remove combustion deposits from the cylinder, cylinder head,
top of piston and around valves per recommended intervals
(see “Maintenance Schedule” on page 16).
AFTER EACH USE
Water should not remain in the unit for long periods of time.
Sediments or minerals can deposit on pump parts and
“freeze” pump action. Follow these procedures after every
use:
1.
Flush detergent siphoning tube by placing the filter into a
pail of clean water while running pressure washer in low
pressure mode. Flush for one to two minutes.
2.
Shut off engine, turn off water supply, point gun in a
safe direction and squeeze trigger to relieve trapped
pressure, engage trigger lock on spray gun and let
engine cool.
3.
Disconnect hose from spray gun and high pressure
outlet on pump. Drain water from hose, gun, and nozzle
extension. Use a rag to wipe off the hose.
4.
Empty pump of all pumped liquids by pulling recoil
handle about six times. This should remove most liquid
in pump.
5.
Store unit in a clean, dry area.
6.
If storing for more than 30 days, see “Long Term
Storage” on next page.
Keep areas within heavy line clear of debris.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 5 ft. (152 cm) clearance on all sides of pressure
washer including overhead.
• Code of Federal Regulation (CFR) Title 36 Parks, Forests, and
Public Property require equipment powered by an internal
combustion engine to have a spark arrester, maintained in
effective working order, complying to USDA Forest service
standard 5100-1C or later revision. In the State of California a
spark arrester is required under section 4442 of the California
Public resources code. Other states may have similar laws.
Contact with muffler area can result in serious
burns.
Exhaust heat/gases can ignite combustibles,
structures or damage fuel tank causing a fire.
WARNING
WHEN STORING FUEL OR EQUIPMENT WITH FUEL IN TANK
• Store away from furnaces, stoves, water heaters, clothes dryers
or other appliances that have pilot light or other ignition source
because they can ignite fuel vapors.
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or
death.
WARNING
• Keep high pressure hose connected to pump and spray gun
while system is pressurized.
• ALWAYS point gun in safe direction and squeeze spray gun
trigger, to release high pressure, every time you stop engine.
Engage trigger lock when not in use.
The high pressure stream of water that this
equipment produces can cut through skin and its
underlying tissues, leading to serious injury and
possible amputation.
Spray gun traps high water pressure, even when
engine is stopped and water is disconnected,
which can cause injury.
