Adjusting the Glide Movement of the Glide Arm
(see figure F)
The glide mechanism of glide arm 28 is factory-preset, and
not set to glide movement upon delivery of the power tool.
The glide movement of the glide movement controller can be
individually adjusted on the controller 54:
Hard – for more controlled work motion;
Soft – for fast saw cuts.
– For softer damping, loosen both set screws 55 using the
Allen key (4 mm) 20
or
tighten both set screws 55 for harder damping.
Clamping the Workpiece (see figure G)
To ensure optimum working safety, the workpiece must al-
ways be firmly clamped.
Do not saw workpieces that are too small to clamp.
– Press the workpiece firmly against the fence 10.
– Insert the material clamp 22 provided into one of the holes
56 intended for it.
– Loosen the wing bolt 57 and adapt the material clamp to
the workpiece. Tighten the wing bolt again.
– Firmly clamp the workpiece by turning the threaded rod
58 in clockwise direction.
Adjusting Mitre Angles
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 43).
f
Always tighten the locking knob 15 firmly before saw-
ing. Otherwise the saw blade can become wedged in the
workpiece.
Adjusting Standard Mitre Angles (see figure H)
For quick and precise adjustment of commonly used mitre an-
gles, detents 18 have been provided for on the saw table:
– Loosen the locking knob 15 in case it is tightened.
– Pull lever 16 and rotate the saw table 38 left or right to the
requested detent.
– Release the lever again. The lever must be felt to engage in
the detent.
Adjusting Any Mitre Angle (see figure I)
The mitre angle can be set in the range from 52° (left side) to
60° (right side).
– Loosen the locking knob 15 in case it is tightened.
– Pull lever 16 and at the same time, push mitre detent over-
ride 14 down at the front.
This locks lever 16 and the saw table can move freely.
– Turn the saw table 38 left or right by the locking knob until
the angle indicator 59 indicates the requested mitre angle.
– Tighten the locking knob 15 again.
– To loosen the lever 16 again (for adjusting standard mitre
angles), pull the lever upward.
The mitre detent override 14 snaps back to its original po-
sition and lever 16 can re-engage into the detents 18.
Adjusting Bevel Angles
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 43).
The vertical bevel angle can be adjusted in a range from 47°
(leftward) to 47° (rightward).
For quick and precise setting of frequently used bevel angles,
stops have been provided for the angles 0°, 22.5°, 45° and
47°.
Adjusting the Lefthand Bevel Angle
Range(45° to 0°)
– Pull the left fence extension 9 completely outward. (see
“Extending the Fence”, page 38)
– Loosen the lock lever 17.
– Tilt the glide arm via handle 4 leftward until the angle indi-
cator 33 indicates the desired bevel angle.
– Hold the glide arm in this position and tighten lock lever 17
again.
The clamping force of the lock lever must securely hold the
position of the glide arm at any bevel angle.
Adjusting the Righthand Bevel Angle
Range(0° to 45°) (see figure J)
– Pull the right fence extension 9 completely
outward. (see “Extending the Fence”,
page 38)
– Loosen the lock lever 17.
– Lightly tilt the glide arm leftward out of the 0°position via
handle 4 and turn rotary knob 39 until the desired bevel
angle range is indicated.
– Tilt the glide arm via handle 4 to the right until angle indica-
tor 24 indicates the desired bevel angle.
– Hold the glide arm in this position and tighten lock lever 17
again.
The clamping force of the lock lever must securely hold the
position of the glide arm at any bevel angle.
Standard 0° Bevel Angle
To enable simple and swift resetting of the standard 0° bevel
angle, rotary knob 39 will engage in the bevel angle range
.
– Tilt the glide arm from right to left over the 0° position.
Adjusting the Complete Bevel Angle
Range(–47° to +47°)
– Pull both fence extensions 9 completely out-
ward. (see “Extending the Fence”, page 38)
– Loosen the lock lever 17.
– Lightly tilt the glide arm leftward out of the
0°position via handle 4 and turn rotary knob 39 until the
desired bevel angle range is indicated.
– Tilt the glide arm via handle 4 to the left or right until angle
indicator 33 or 24 indicate the desired bevel angle.
