- Automatic length compensation for preferred angles 5/10/15/22.5/30/45/60/67.5°
- An imprinted scale simplifies the production of incorrect mitres
- Easy handling and quick mounting on the trolley of the saw
- Angle & length measurement adjustable via digital display
- The leg length available for cutting is maximum 1375 mm
- Including wooden support block and wall bracket
- Bounce-free mounted flip stops
- Including adapter
Operating Elements
Working with the DSG-D
Placing the fence on the Panhans edging table
CAUTION: Secure the machine against an unintentional switch-on!
- Move eccentric lever to “handle up” position.
- Place the fence on the edging table.
- Check whether the press-on screws are in contact with the edging table and re-adjust if necessary.
- Loosen the two M8 screws. This ensures that the fence rests correctly on the edging table.
- Clamp the fence by tightening the eccentric lever.
- Retighten the two M8 screws.
Adjusting the fence
Note: Precise adjustment of the DSG-D fence is of enormous importance, as it affects the accuracy of all cuts made with it. To achieve optimum cutting results, always use sufficiently precise measuring equipment (e.g. vernier calliper) for adjustment.
-
Swivel the fence to approximately 45° and loosen the four M8 clamping screws (Figure 1).
-
Now swivel the fence to-wards position 0 (≙ 90°) until the stop screws are in contact (Figure 2).
-
The line in the magnifying glass for reading the swivel angle is now congruent with the 0 resp. 90° line on the angle scale.
-
Clamp the turntable at this position.
-
Insert the support block into the fence profile, which is approximately parallel to the saw blade.
CAUTION: Make sure that the support block is in contact with the profile! -
Carefully push the fence with the material up to the saw blade (Figure 3). CAUTION: To prevent the saw blade from being pushed out of position, place an additional material strip to the right of the saw blade and fix it in place with the rip fence!
-
At this position, retighten the M8 clamping screws –first on one side.
Then swivel the fence so that the two clamping screws on the other side can be easily reached and tighten them as well. -
Make a test cut in the 0° resp. 90° position and check whether the position of the scale corresponds to the value measured on the test piece.
-
The length measurement must correspond to position “0” (≙ 90°) on the angle scale (Figure 4).
-
If the length measurement does not correspond to the “0” position, leave the DSG-D fence in the clamped state, loosen the screws of the scale, and move it until the 0 of the upper scale corresponds exactly to the measured value (Figure 4). Then re-tighten the screws.
-
Then slide the flap rail into the other profile and check the length here as well. Because the fence scale has different markings for reading the length, it is possible to set the exact length to the cutting line at certain angles.
Example: If, for example, the fence is set to an angle of 22.5° and the length dimension is set so that the marking line on the scale below the 22.5 is congruent with any measure (for example 350 mm) on the scale of the profile, this value is cut measured in the tip (see Figure 5).
The measuring scale in the profile has two measurement rows:
- Upper scale → First stop flap
- Lower scale→ Second stop flap (distance = 640 mm)
The maximum cutting length at position “0” resp. 90° is 1375 mm. If this dimension is to be cut at (for example) 45°, the clamping screw for the flap rail must be offset as shown in Figure 6.
Produce wrong mitres
To produce incorrect mitres, the DSG-D has a patented printed scale that makes
it easy to set the correct angle for the wider and narrower workpiece at the
same time.
The procedure is very simple.
Example:
- Measure the width of wider workpiece (e.g. 180 mm)
- Measure the width of the narrower workpiece (e.g. 100 mm)
- Calculate factor 180 100= 1,8
- Turn the turntable as shown in Figure 7 with the large magnifying glass (L) to a factor of 1.8 and clamp it tight.
This automatically results in the correct angle to the saw blade for the narrower workpiece (S) on the left side of the DSG-D and for the wider workpiece (B) on the right (refer to Figure 8). The corresponding sides for the narrow and wide workpiece are also shown graphically on the turntable plate.
Table for length compensation on the double-sided mitre fence
Using the table (refer to section 2.5) the length compensation dimension can
be set in addition to the angles printed on the scale of the mitre fence
(refer to Figure 9).
Example: If a tip dimension of 350 mm is
to be set for an angle of 17.5°, the length compensation results in the value
of 29.0 mm according to the table on the next page. This value must now be
added to the value 350 mm (≙ 35 on the length scale). Thus the 0 on the scale
of the stop rail must now be set congruent with 37.9 (≙ 379 mm) on the length
scale. Values with a minus (marked red in the table) are to be subtracted from
the tip dimension.

Digital Angle Display
2.6.1 Calibrate indicator to the fence
Pressing the key will set the display to the value 0.00. This can be done
at any angle setting of the fence.
To return the display to its original position (0.00 at 0° resp. 90°), swing
the fence against the fence screws (refer to Figure 2) and then press key.
2.6.2 Battery change
The power supply for the position indicator is provided by two 1.5 Volt
batteries type Micro “AAA”, which are accessible by loosening the two screws
of the battery case on the rear of the unit. When the battery symbol (see
Figure 10) appears in the display, the battery should be replaced as soon as
possible. Please ensure that the polarity is correct (see Figure 11).
Since the current angular position is not saved when the battery is changed,
the indicator must be recalibrated to the fence afterwards (as described in
section 2.6.1).
Fire, explosion and burn hazard! Never recharge batteries or expose them to
temperatures above 85° C. Please dispose of the used batteries properly.

Wall Bracket
The wall bracket for the DSG-D offers a practical way to store the fence
within easy reach when not in use. It is already included in the scope of
delivery.
The two clamping pins shown in Figure 12 are located on the underside of the
fence. They can be used for quick and tool-free attachment of the device to
the wall bracket.
