Adjustments for Mitre Saw Mode

WARNING: Be aware the saw blade shall be replaced in the described way only. Only use
saw blades as specified under Technical Data; Cat.no.: DT4321.
Your mitre saw was accurately adjusted at the factory. If readjustment due to shipping and
handling or any other reason is required, follow the steps below to adjust your saw. Once
made, these adjustments should remain accurate.
Checking and Adjusting the Blade to the Fence (Fig. G1, G2, H)
With the head in the vertical position and the bevel clamp handle

 65 
in the rotating table location plunger 
1. Pull down the head until the blade just enters the saw kerf.
2. Place a square 
 66 
against the left side 
should be 90°.

WARNING: Do not touch the tips of the blade teeth with the square.
3. If adjustment is required, proceed as follows:
a. Rotate the eccentric adjustment bush 
the square (Fig. G1).
b. Tighten the locking screw 
 65 
.
4. Check that the red marks 
 68 
near the blade slot 
the two scales (Fig. H).
5. If adjustment is required, loosen the screws 
position should now also be accurate. If this is not the case, the blade is not perpendicular
to the rotating table (see below).
Checking and Adjusting the Blade to the Table (Fig. I1, I2)
1. Loosen the bevel clamp knob 
 22 
(Fig. I1).
2. Press the saw head to the right to ensure it is fully vertical and tighten the bevel
clamp handle.
3. Pull down the head until the blade just enters the saw kerf.
4. Place a set square 
 66 
on the table and up against the blade 
be 90°.

WARNING: Do not touch the tips of the blade teeth with the square.
5. If adjustment is required, proceed as follows:
a. Loosen the bevel clamp knob 
 22 
(Fig. I1) and turn the vertical position adjustment
stop screw 
in or out until the blade is at 90° to the table as measured with the
 71 
square 
 66 
(Fig. I2).
Checking and Adjusting the Mitre Angle (Fig. A1, A2, H)
The straight cross-cut and 45° mitre positions are pre-set.
1. Pull up the rotating table location plunger 
turn (Fig. A1).
2. Loosen the rotating table clamp 
 3 
. The handle allows a ratchet-type action when full
rotation of the handle is not possible.
3. Grip the control handle 
 14 
(Fig. A2), compress the guard release lever 
saw about halfway (Fig. A1).
4. Turn the sawhead with its rotating table to the required position.
5. Tighten the rotating table clamp 
. The rotating table location plunger 
 3 
automatically (Fig. A1).
6. Using the red marks 
 68 
, the mitre saw table 
between 0° and 45° (Fig. H).
7. Proceed as for pre-set positions. The rotating table location plunger cannot be used for
intermediate angles.

WARNING: Always make a trial cut in a piece of waste wood, to check for accuracy.
Adjusting the Fence (Fig. J1, J2)
The moveable part of the left side of the fence can be adjusted to provide maximum support
of the workpiece near the blade, while allowing the saw to bevel to a full 45° left. The sliding
distance is limited by stops in both directions. To adjust the fence 
1. Lift the lever 
 72 
to release the fence 
 7 
2. Slide the fence to the left.
3. Make a dry run with the saw switched off and check for clearance. Adjust the fence to
be as close to the blade as practical to provide maximum workpiece support, without
interfering with the up and down movement of the arm.
4. Push the lever 
 72 
down to secure the fence in place.

Assembly for Bench Saw Mode
Changing from Mitre Saw to Bench saw Mode
(Fig. A1–A3, E2, L1, L2)
1. Put the blade into 0° cross-cut position with the rotating table location plunger 
correctly located and the rotating table clamp 
2. Slacken the riving knife clamp bolt 
mounting slot (Fig. L1).
3. Take the riving knife 
from its storage position against the saw head (Fig. A2).

4. Depress the guard release lever 
guard as far as possible (Fig. A1).
5. Slide the riving knife bracket 
clamp bolt.
6. Gently release the lower guard until it is held in place behind the edge protruding from
the inside of the riving knife.
7. Remove the under-table guard.
8. Pull down the saw head and swing the height adjuster 
engages on the pin provided in the base (Fig. E2).
9. Turn the wheel 
 55 
of the adjuster to make the blade and riving knife protrude from the
bench saw table 
 24 
(Fig. A3) to provide maximum cutting depth in bench saw mode.

WARNING: The blade should not foul the lower blade guard.

WARNING: Be careful not to lose control over the movement of the table.
Position of the Riving Knife (Fig. M)
Fit the riving knife 
as described above. Once fitted, the riving knife does not require
 16 
further adjustment.
Fitting the Upper Blade Guard (Fig. N)
The upper blade guard 
is designed to be quickly and easily attached, via a spring-loaded
 25 
plunger to the hole in the riving knife 
for bench saw mode.
Secure the upper blade guard 
plunger in the guard to engage.

WARNING: Never use your saw in bench saw mode without the upper guard
correctly fitted.
Mounting and Adjusting the Parallel Fence (Fig. O)

 77 
.
2. Slide the bracket on from the left or the right. The clamping plate 
front edge of the table.
3. Tighten the knob 
 77 
.
4. Check that the fence is parallel to the blade.
5. If adjustment is required, proceed as follows:
a. Adjust the fence so that it is parallel to the blade by checking the distance between the
blade and the fence at the front and rear of the blade. To do so, turn the adjustment
screw in the fence support in or out as necessary.
The default set-up of the fence is to the right-hand side of the blade.
To prepare the fence for use to the left-hand side of the blade, proceed as follows:
1. Loosen the knob 
 77 
.
2. Pull out the bracket 
and replace it in the other end.
 79 
3. Fit the fence to the table.
4. Tighten the knob 
 77 
.

WARNING: Use the 11 mm profile for ripping low workpieces to allow access between the
blade and the fence for the push stick 

WARNING: The rear end of the fence should be level with the front of the riving knife.
Changing from Bench saw to Mitre Saw Mode (Fig. A3, D, E2, L1)
1. Remove the parallel fence 
2. Turn the wheel
