WARNING
To reduce the risk of fuel spillage and
fire from an improperly installed fuel cap,
correctly position and tighten the fuel
cap in the fuel tank opening.
WARNING
See the Kohler owner's manual for
additional warnings and instructions
related to fuel and fueling.
Connecting the water supply
If hooking up the pressure washer to a
potable water system, a backflow
preventer must be installed between the
water tap and the hose. The design of
the backflow preventer must comply with
the applicable country-specific
regulations.
WARNING
If potable water has passed through the
backflow preventer, it can no longer be
regarded as potable water.
Follow the rules laid down by the local
water supply company to prevent water
flowing back from the pressure washer
into the drinking water main.
Do not use the machine with dirty water
(i.e., water that contains sand, dirt or
other particulate matter). If there is a risk
that the water supply is dirty, use an
appropriate water filter or find an
alternative water source.
Before Starting
WARNING
The machine may only be used when all
parts are in proper working order. Never
operate your pressure washer if it is
modified, damaged, improperly adjusted
or maintained, or not completely or
securely assembled. Never run the
pressure washer with a modified or
disconnected governor. Never attempt
to modify the controls or safety devices.
WARNING
Check the fuel system for leaks,
especially the visible parts, e.g., filler
cap, hose connections. To reduce the
risk of personal injury or property
damage from fire, do not start the engine
if the unit is leaking or showing other
signs of damage. Have the machine
repaired by an authorized STIHL
servicing dealer before using it.
WARNING
Check that the spark plug boot is
securely mounted on the spark plug – a
loose boot may cause arcing that could
ignite combustible fumes and cause a
fire.
WARNING
Check the on-off switch, choke lever,
fuel shut-off and throttle lever for proper
function. The throttle lever must move
freely.
WARNING
Ensure that the high-pressure hose is in
good condition and not frayed, cracked,
deformed or damaged in any way. Never
operate the machine with a damaged or
worn high-pressure hose – replace it
before further use. Using a worn or
damaged hose, or one that does not
meet the high pressure requirements of
the pressure washer, can result in
personal injury. If using a replacement or
extension high-pressure hose, ensure
that it is rated for the maximum PSI of
Always refuel slowly and
take care to avoid fuel
spillage which may cause
a risk of fire.
Check for fuel leakage
while refueling and during
operation. If fuel leakage
is found, do not start or
run the machine until the
leak is fixed and any
leaked fuel has been
wiped away. Take care
not to get fuel on your
clothing. If this happens,
change your clothing
immediately.
Do not overfill the fuel
tank. Leave 5/8 inch
(16 mm) of space at the
top of the tank to allow for
fuel expansion.
Unit vibrations can cause
an improperly installed
fuel cap to loosen or
come off and spill quanti-
ties of fuel. In order to
reduce the risk of fuel
spillage and fire, tighten
the fuel filler cap by hand
as securely as possible.
Do not connect the pres-
sure washer directly to a
potable water system.
