• Recommendedcleaningprocedure
• Dissolvedirtbyapplyingdetergentwiththefan
jet to the dry surface.
• Onverticalsurfaces,workfromthebottom
upwards. Leave the detergent to act for 1 to 2
minutes, but do not allow to dry out. Apply the

9
EN
high pressure jet, keeping the nozzle at least
30 cm (10 in.) from the surface, working from
the bottom upwards. Avoid allowing the rinsing
water to run on to unwashed surfaces.
• Shuttingdownthepressurewasher
The use of detergents can dramatically reduce
cleaning time and assist in the removal of difficult
stains. Some detergents have been customized
for pressure washer use on specific cleaning
tasks. These detergents are approximately as
thick as water. The use of thicker detergents,
such as dish soap, will clog the chemical
injection system and prevent the application of
the detergent. The cleaning power of detergents
comes from applying them to a surface and
giving the chemicals time to break down the dirt
and grime. Detergents work best when applied
at low pressure. The combination of chemical
action and high pressure rinsing is very effective.
On vertical surfaces, apply the detergent starting
at the bottom and work your way upward. This
will prevent the detergent from sliding down and
causing streaks. High pressure rinsing should also
progress from the bottom to top. On particularly
tough stains, it may be necessary to use a brush
in combination with detergents and high pressure
rinsing.
CAUTION! Never disconnect the high-
pressure hose from the machine while
the system is still pressurized.
Follow the correct procedure:
1. Turn off the pressure washer by using the
switch on the machine.
2. Unplug the unit from the power source.
3. Turn off the water supply at the tap.
4. Press the trigger of the gun to depressurize the
system.
5. Disconnect the supply hose to the machine
6. Wipe all surfaces of the unit with a damp clean
cloth.
7. Engage the safety lock.
5. SERVICE & MAINTENANCE
Warning! Unplug the electric cable
(power source) prior to any maintenance
or preparatory storage operations.
• Makesurethatthemachineisnotlivewhen
carrying out maintenance work on the motor.
• Toensuregoodperformance,checkandclean
the suction and detergent filters after every 50
hours of operation.
