Electronic water control
STIHL cut-off machines may be
equipped with an electronic water
control system.
The electronic water control makes it
possible to feed the optimum amount of
water to the cutting wheel. No water is
fed to the cutting wheel during idling or
when the machine is turned off.
Before starting work
Familiarize yourself with the control
N
panel and sequence of motions
while the engine is switched off.
All of the control panel buttons can
N
be reached with the thumb of the
right hand while the right hand
remains on the rear handle.
The left hand always remains on the
N
handlebar.
Control Panel
When the engine is running, it is
possible to activate/deactivate the
electronic water control and adjust the
water flow.

wheel.
Using the Electronic Water Control
Start engine: see the chapter
N
"Starting/Stopping the Engine."
Briefly push the (+) button or (–)
N
button with the thumb of the right
hand. The right hand must always
remain on the rear handle while
doing so; the left hand must always
remain on the handlebar. No water
is fed to the cutting wheel during
idling.
During use, the set amount of water is
fed to the cutting wheel.
Adjust water flow if necessary – to
N
do so, briefly push the (+) button or
(–) button with the thumb of the right
hand until the correct water quantity
is attained at one of the settings.
The right hand must always remain
on the rear handle while doing so;
the left hand must always remain on
the handlebar.
The water pressure will affect the actual
amount of water flow at any setting. It
may be necessary to use a higher
setting with a lower water pressure, e.g.,
when using a pressurized or gravity
water tank. For proper dust suppression
and cutting performance, always make
sure that the water flow is within the
proper range, as described in the
chapter "Sample Applications."
If the cut-off machine is idling after use,
no more water will be fed to the cutting
wheel – the electronic water control,
however, remains activated. With
continued use, the last setting will be
automatically re-entered.
If the engine is stopped and restarted,
the electronic water control is switched
off.
Maintenance and Care
If too little water or no water is fed to the
cutting wheel during use although the
electronic water control has been
activated:
