Operation
5.1 Initial operation
Personnel entrusted to work with the machine must
be made aware of the operating instructions, calling

attention
instructions".
5.2 Switching on and off
Danger
Before switching on the machine,
pay attention that the guide rail and
the saw chain are unobstructed.
The workspace underneath the
workpiece must be free of
obstacles. Lead the connecting
cable away to the rear. Hold the
machine with both hands by the
handles provided for that purpose.
•
Switching on: First unlock the switch-on lock
by pressing the locking lever 10.1 (Fig. 1) to the
front. Then actuate the control lever 10. As this
is a switch without locking device, the machine
will only run for as long as this switch is
pressed.
The carpenter's chain saw ZSX Ec is equipped with
an electronic speed control. The speed is
continuously variable between 3000 and 3600 rpm.
The required speed is set with the aid of the setting
wheel 30 (Fig. 1).
When using a carbide or fine-cut chain, it is
recommended to set the speed to the lowest value.
When using a cross cut chain set it to the highest
value.
The built-in electronic system provides for jerk-free
acceleration when the machine is switched on and
under load readjusts the speed to the fixed setting.
•
Switching off: To switch off, release the switch
trigger 10. The switch-on lock automatically
takes effect again and secures the carpenter's
chain saw against accidental switch-on.
On switching off the machine, the automatic brake
takes effect simultaneously. This shortens the slowing
time of the saw chain to approx. 1 second.

"Safety
5.3 Work instructions
The handling and layout of the carpenter's chain saw
ZSX Ec corresponds to a portable circular saw. The
riving knife/splitter 4 prevents the saw chain from
jamming and the safeguard of the bottom chain
deflection a turning up of the machine. It is
particularly suited for cross cuts requiring a large
cutting depth, in particular also for joining laminated
timber.
Before switching on, place the machine with its base
plate 3 such onto the workpiece that there is not yet
any contact between saw chain and workpiece. Hold
the machine by both handles 1 and 2 and after
switching on, slide evenly forwards without canting.
Therefore, if possible, always guide the machine with
the parallel stop either along the workpiece edge or
along a guide rail that is available as special
accessory (see section 4.5). The use of a guide rail
achieves a clearly higher cut quality.
5.4 Large cutting lengths
For large cutting lengths (e.g. several beams in a
row) the guide rail can be tilted to the rear by 10° (see
Fig. 5). This makes it easier to guide the machine
straight ahead, in particular at the transition from one
workpiece to the next.
Danger
Pull the power plug during all
service work.
For tilting, first of all the two set screws 28 (Fig. 5)
are unfastened and the chain guide rail is tilted up to
the limit stop in the direction of the rear handle. Then
tighten the set screws again.

Service and maintenance
Danger
Pull the power plug during all
service work.
MAFELL machines are designed to be low in
maintenance.
The ball bearings used are greased for life. When the
machine has been in operation for a longer period of
time, we recommend to hand the machine in at an
authorised MAFELL customer service shop for
inspection.
