Sawing
Sawing without Slide Movement (Cutting Off)
(see figure P)
– Slide glide arm 28 completely to the rear and secure it in
this position (see "Securing the Glide Arm", page 38).
Make sure that the depth stop 30 is pushed completely in-
ward and that adjusting screw 29 fits through the recess
without touching the depth stop when moving the glide
arm.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Adjust the desired mitre and/or bevel angle.
– Switch on the machine.
– Press locking lever 5 and slowly guide the glide arm down-
ward with handle 4.
– Saw through the workpiece applying uniform feed.
– Switch off the machine and wait until the saw blade has
come to a complete stop.
– Slowly guide the glide arm upward.
Sawing with Slide Movement (see figure Q)
 Before switching on and during the complete sawing,
hold the handle firmly. While sawing, carry out a con-
trolled motion with the glide arm. A moment of inatten-
tion while operating the extremely smooth-running glide
arm can result in serious personal injury.
– Release glide arm 28 (see "Releasing the Glide Arm",
page 38).
Check if the complete glide mechanism is operative by
sliding the glide arm 28 back and forth. – Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Adjust the desired mitre and/or bevel angle.
– Pull the glide arm away from the fence 10 until the saw
blade is in front of the workpiece.
– Switch on the machine.
– Press locking lever 5 and slowly guide the glide arm down-
ward with handle 4.
– Now, push the glide arm toward the fence 10 and saw
through the workpiece with uniform feed.

– Switch off the machine and wait until the saw blade has
come to a complete stop.
– Slowly guide the glide arm upward.
Sawing Workpieces of the Same Length (see figure R)
The material stop 36 can be used for easily sawing workpiec-
es to the same length.
The material stop can be mounted on either side of the saw ta-
ble extension 11.
– Loosen lock screw 35 and swing the material stop 36 over
clamping screw 63.
– Retighten lock screw 35.
– Adjust the saw table extension 11 to the desired length
(see "Extending the Saw Table", page 38).
Adjusting the Depth Stop (Sawing Grooves)
(see figure S)
The depth stop must be adjusted when sawing a groove or
using a spacer.
– Swivel the depth stop 30 outward.
– Press locking lever 5 and tilt the glide arm to the desired
position.
– Turn adjusting screw 29, until the screw end touches
depth stop 30.
– Slowly guide the glide arm upward.
Special Workpieces
When sawing curved or round workpieces, these must be
especially secured against slipping. At the cutting line, no gap
may exist between workpiece, fence and saw table.
Provide for special fixtures, if required.
Sawing Profile Strips/Mouldings
(Floor and Ceiling Strips)
Profile strips/mouldings can be sawn in two different ways:
– Placed against the fence
– Lying flat on the saw table.
In addition, the cut can be perfomed with or without slide move-
ment depending on the width of the profile strip/moulding.
Always make trial cuts with the mitre angle setting first on
scrap wood.
