Cleaning

WARNING! Do not use a high pressure
!
washer when rinsing the inside of the
machine.
The machine can withstand taking in damp air and
splashes during the cutting process. Clean water does
not affect the machine's function.
When cutting materials such as concrete or brick, which
can contain salt, you must rinse the machine after the
work is finished. The cleaning reduces the risk for
accretions building up inside the engine, which can cause
leakage current between electric components, which in
turn can cause the ground fault circuit interrupter to turn
off without intention.
• Clean the machine daily by rinsing it with clean water
after the work is finished.
• Place the machine with the rear handle facing
upwards. Rinse the air intakes at the rear handle with
clean water. The water will run out through the front air
outlets.
• Connect the plug and run the engine dry for approx.
30 sec in order to speed up the drying of the engine.
Cooling system
• The machine is equipped with an efficient fan to cool
the motor. Cooling air which is drawn in through the
grille by the machines rear handle passes over the
stator and rotor and out through the front of the motor
housing.
• In order for the machine to always be cooled
sufficiently the cooling air openings must be kept clear
and clean. Blow down the machine regularly with
compressed air.
