Do not direct the high-pressure jet into 
places you cannot see.
Never direct the high-pressure jet 
toward the pressure washer itself or any 
of its components.
To reduce the risk of property damage, 
start work at the greatest effective 
distance from the surface being cleaned. 
Do not move so close that the surface is 
damaged by the force of the spray.
Be especially careful when spraying 
softer materials such as fabric. Caution 
should be used when directing spray 
toward fragile materials such as glass. 
Shattering could result in serious injury.
The machine must not be covered 
during use or while the engine is still 
warm. Ensure that the engine is cooled 
sufficiently before covering.
If you feel sick, if you have a headache, 
vision problems (e.g., your field of vision 
gets smaller), hearing problems, 
dizziness or inability to concentrate, stop 
work immediately. Such symptoms may 
be caused by an excessively high 
concentration of exhaust emissions.
After finishing work
Shut off the engine after finishing work. 
Then turn off the water supply and 
squeeze the spray gun trigger to release 
trapped pressure. Engage the trigger 
lockout when not in use.
Disconnect the water intake hose 
between the machine and water supply.
MAINTENANCE, REPAIR AND 
STORING
If you make a warranty claim for a 
component which has not been serviced 
or maintained properly, STIHL may deny 
coverage.
WARNING
To reduce the risk of serious or fatal 
injury, STIHL recommends using only 
authorized STIHL or Kohler replacement 
parts for maintenance and repair. Strictly 
follow the maintenance and repair 
instructions in this instruction manual 
and the Kohler owner's manual.
WARNING
High-pressure hoses, fittings and 
couplings are important for machine 
safety. STIHL recommends using only 
high-pressure hoses, fittings, couplings 
and other accessories that have been 
approved by STIHL for this machine, or 
technically equivalent parts. Contact 
your authorized STIHL servicing dealer 
for a list of authorized parts and 
accessories.
The high-pressure hose and all fittings, 
couplings, spray nozzles and 
accessories must be approved for the 
permissible excess pressure of the 
machine.
The permissible excess pressure, the 
maximum permitted temperature and 
the date of manufacture are stated on 
the cladding of the high-pressure hose.
WARNING
Before performing any inspection, 
maintenance, cleaning or other work on 
the machine, shut off the engine, turn off 
the water supply and squeeze the spray 
gun trigger until the pressure in the 
system has been fully released. Do not 
attempt any maintenance or repair work 
not described in this instruction manual. 
STIHL recommends that you have such 
work performed by your STIHL servicing 
dealer.
Do not clean your machine with a 
pressure washer. The solid jet of water 
may damage parts of the machine.
WARNING
To reduce the risk of fire and burn injury 
or property damage, use only spark 
plugs authorized by STIHL or Kohler. 
Always press the spark plug boot snugly 
onto the spark plug terminal of the 
proper size. (Note: If terminal has 
detachable SAE adapter nut, it must be 
securely attached.) A loose connection 
between spark plug terminal and the 
ignition wire connector in the boot may 
create arcing that could ignite 
combustible fumes and cause a fire. 
To reduce the risk of 
short-circuiting, fire and 
electrocution, never 
direct the spray at electri-
cal appliances and 
equipment, sockets or 
power cords.
