9 Connecting the Water Supply
► Shut off the water supply.
► STIHL recommends attaching the water filter (2).
The water filter helps keep sand and dirt out of the pump,
thereby helping to protect components from damage.
► Screw the coupling (1) onto the pressure washer or water
filter (2) and tighten by hand.
► Connect the water hose (4).
► If the spray lance is attached to the spray gun: remove the
spray lance.
► Turn on the water supply.
► Pull the spray gun trigger until a steady, even water jet is
delivered from the spray gun.
► Switch off the pressure washer.
► Lock the spray gun trigger.
► Connect the spray lance.
► Insert the nozzle, @ 8.4.1.
NOTICE
Running the pressure washer without water will cause the
pump to overheat, which may result in permanent damage.
Always connect and turn on the water supply to the pump
before starting the motor. Do not operate the pressure
washer without water.
Disconnecting the Water Hose
To disconnect the water hose:
► Switch off the pressure washer, @ 10.2.
► Disconnect the pressure washer from the power supply.
► Shut off the water supply.
► Pull the spray gun trigger to relieve pressure.
► Lock the spray gun trigger.
► Remove the water hose (4) from the coupling (1) onto the
pressure washer or water filter (2).
9.2 Connecting the pressure washer to another
water source
WARNING
Make sure the pressure washer is switched off and
disconnected from the power supply before connecting to or
disconnecting from another water source.
The pressure washer can draw water from water butts and
cisterns and from running or stagnant bodies of water.
