Using detergents
Fig. 1 & 3
The built-in detergent dispenser will allow you
to apply many forms of liquid detergent onto the
work surface. Detergent application happens at
low-pressure only.
• Insert the adjustable nozzle onto the gun.
• Adjust the nozzle to low pressure setting. (Fig. 3)
• Remove the cap on the detergent reservoir
(11 in Fig. 1) and fill with liquid detergent only.
Do not put any water into the reservoir. The
pressure washer will mix water and detergent
automatically. When finished applying the
detergent to the work surface, it is possible
to spray off the detergent by using the high-
pressure setting (Fig. 3). In high-pressure mode,
the pressure washer will not dispense detergent.
Adjusting the detergent rate
Fig. 4
To adjust the rate detergent is mixed with the
water you can turn the detergent knob.
• Turn left to decrease the amount of detergent
added.
• Turn Right to increase the amount of detergent
added.
Water inlet filter
• The water inlet filter must be inspected regu-
larly, so as to avoid blockage and restriction of
the water supply to the pump.
CAUTION! Never disconnect the high-
pressure hose from the machine while
the system is still pressurized.
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.
• When the nozzle is clogged, it may cause
failure. The nozzle can be cleaned by inserting
the 'cleaning pin' into the tip to remove filth.
