Mounting the Extension Bars (see figure
To extend the saw table additionally, extension
bars can be mounted both to the left or right of
the power tool.
– Insert the extension bars 43 on both sides of
the power tool to the stop in the drill holes
44 intended for this purpose.
– Firmly tighten the screws of the extension
bar.
Clamping the Workpiece (see figure
To ensure optimum working safety, the work-
piece must always be firmly clamped.
Do not saw workpieces that are too small to
clamp.
While clamping the workpiece, do not reach
under the clamping lever of the quick-
action clamp with your fingers.
– Press the workpiece firmly against the
fence 32.
– Insert the quick-action clamp 23 into one of
the holes 30 intended for this purpose.
– Adapt the quick-action clamp to the work-
piece by turning the threaded rod 45.
– Push on the clamping lever 46 in order to
clamp the workpiece.
Adjusting the Cutting Angle
To ensure precise cuts, the basic adjustment of
the machine must be checked and adjusted as
necessary after intensive use (see "Checking
and Adjusting the Basic Adjustment", page 65).
Always tighten the locking knob 27 firmly
before sawing. Otherwise the saw blade can
become wedged in the workpiece.
– Bring the power tool into the chop and mitre
saw working position. (see "Working Posi-
tion", page 59)
