Basic Saw Cuts
Quality of Cut
The smoothness of any cut depends on a number of variables, e.g. the material being cut.
When smoothest cuts are desired for moulding and other precision work, a sharp (60 tooth
carbide) blade and a slower, even cutting rate will produce the desired results.

WARNING: Ensure that the material does not creep while cutting; clamp it securely
in place. Always let the blade come to a full stop before raising the arm. If small fibres
of wood still split out at the rear of the workpiece, stick a piece of masking tape on the
wood where the cut will be made. Saw through the tape and carefully remove tape
when finished.
Dust Extraction (Fig. A5)
The machine is provided with a 38 mm dust extraction port on the upper blade guard.
• Connect a suitable dust extraction device, designed in accordance with the relevant
regulations regarding dust emission, during all sawing operations.
Sawing in Mitre Saw Mode
It is dangerous to operate without guarding. Guards must be in position when sawing.
General Handling
• In the mitre saw mode, the sawhead is automatically locked in the upper "park"-position.
• Squeezing the guard release lever will unlock the sawhead. Moving the sawhead down
retracts the movable lower guard.
• Never seek to prevent the lower guard returning to its park position when the cut
is completed.
• The D27111 saw can cut workpieces up to 220 mm width by 90 mm height. The D27112
saw can cut workpieces up to 285 mm width by 90 mm height. For the proper cutting
capacities, refer to the technical data. The length of the workpiece should never exceed
the base width without adequate support. The end of the workpiece should never be less
than 160 mm away from the blade without additional clamping means.
• In operation, place your hands no closer than 160 mm from the blade. When cutting short
material (min. 160 mm to the left or the right of the blade), the use of the optional material
clamp is required.
• The minimum length of offcut material is 10 mm.
• When cutting workpieces longer than the table width, make sure that the workpiece is
stable over its full length. Support the protruding parts of the workpiece as necessary, e.g.
using the optional workpiece extension.
• When cutting UPVC sections, a supporting piece made out of timber with a
complementary profile should be placed beneath the material being cut to provide the
correct level of support.
Clamping the Workpiece (Fig. A3, W)

WARNING: A workpiece that is clamped, balanced and secure before a cut may become
unbalanced after a cut is completed. An unbalanced load may tip the saw or anything the
saw is attached to, such as a table or workbench. When making a cut that may become
unbalanced, properly support the workpiece and ensure the saw is firmly bolted to a
stable surface. Personal injury may occur.

WARNING: The clamp foot must remain clamped above the base of the saw whenever
the clamp is used. Always clamp the workpiece to the base of the saw – not to any other
part of the work area. Ensure the clamp foot is not clamped on the edge of the base of
the saw.

CAUTION: Always use a work clamp to maintain control and reduce the risk of workpiece
damage and personal injury.
Use the material clamp 26 provided with your saw. Other aids such as spring clamps, bar
clamps or C-clamps may be appropriate for certain sizes and shapes of material.
to Install clamp
1. Insert it into the hole behind the fence. The clamp should be facing toward the back of the
mitre saw. Ensure the groove on the clamp rod is fully inserted into the base of the mitre
saw. If the groove is visible, the clamp will not be secure.
2. Rotate the clamp 180º toward the front of the mitre saw.
3. Loosen the knob to adjust the clamp up or down, then use the fine adjust knob to firmly
clamp the workpiece.
nOtE: Place the clamp on the right side of the base when beveling. ALWAYS MAKE DRY RUNS
(UNPOWERED) BEFORE FINISH CUTS TO CHECK THE PATH OF THE BLADE. ENSURE THE CLAMP
DOES NOT INTERFERE WITH THE ACTION OF THE SAW OR GUARDS.
Vertical Straight Cross Cut (Fig. A1, P)
1. Release the mitre lever 10 and depress the mitre latch
2. Engage the mitre latch at the 0° position and tighten the mitre lever.
3. Place the wood to be cut against the fence (
4. Take hold of the operating handle 2 and depress the head lock up release lever
release the head.
5. Switch the machine on and allow the saw blade to reach full speed.
6. Depress the head to allow the blade to cut through the timber and enter the plastic kerf
plate 8 .
7. After completing the cut, switch the machine off and wait for the saw blade to come to a
complete standstill before returning the head to its upper rest position.
Performing a Sliding Cut (Fig. Q)
The guide rail allows cutting larger workpieces using an out-down-back sliding motion.
1. Release the rail lock knob 18 .

2. Pull the saw head towards you and switch the tool on.
3. Lower the saw blade into the workpiece and push the head back to complete the cut.
4. Proceed as described above.

WARNING:
• Do not perform sliding cuts on workpieces smaller than 50 x 100 mm.
• Remember to lock the saw head in the rear position when the sliding cuts are finished.
Cutting Small Pieces (Fig. K1, K2)
The upper part of the left side of the fence
fence 6 can be adjusted to provide maximum support when cutting small pieces.
1. Put the saw blade into vertical position.
2. Loosen the plastic knob at least 3 full turns.
57
3. Adjust the left fence as close to the blade as possible.
4. Tighten the knob securely.
5. Loosen the wingnut 59 .
6. Adjust the right fence as close to the blade as possible.
7. Tighten the wingnut.
Vertical Mitre Cross-Cut (Fig. A1, R)
1. Release the mitre lever 10 and depress the mitre latch
the required angle.
2. The mitre latch will automatically locate at 10°, 15°, 22.5°, 31.62° and 45° both left and
right, and at 50° left and 60° right. If any intermediate angle is required hold the head
firmly and lock by tightening the mitre lever.
3. Always ensure that the mitre lever is locked tightly before cutting.
4. Proceed as for a vertical straight cross-cut.

WARNING: When mitring the end of a piece of wood with a small off-cut, position
the wood to ensure that the off-cut is to the side of the blade with the greater angle to
the fence:
left mitre, off-cut to the right
right mitre, off-cut to the left.
Bevel Cuts (Fig. A1, K1, S)
Bevel angles can be set from 48° left to 2° right and can be cut with the mitre arm set between
zero and a maximum of 45° mitre position right or left.
1. Loosen the left side fence clamping knob
side fence 13 to the left as far as it will go. Loosen the bevel clamp handle
bevel as desired.
2. Tighten the bevel clamp handle 15 firmly.
3. Proceed as for a vertical straight cross-cut.
Compound Mitre
This cut is a combination of a mitre and a bevel cut.
• Set the bevel angle and subsequently set the mitre angle.
Sawing in the Bench Mode
• Always use the riving knife.
• Always ensure that the riving knife and blade guard are correctly aligned.
• Always ensure that the mitre saw is set and locked in 0° mitre.

WARNING: Do not cut metal in this mode.
Ripping (Fig. T)
1. Set the bevel angle to 0°.
2. Adjust the saw blade height. The correct blade position is to have the tips of three teeth
above the top surface of the wood. Ensure that the saw bench table is securely fixed at the
chosen height.
3. Set the parallel fence to the required distance.
4. Hold the workpiece flat on the table and against the fence. Keep the workpiece approx. 25
mm away from the saw blade.
5. Keep both hands away from the path of the saw blade.
6. Switch the machine on and allow the saw blade to reach full speed.
7. Slowly feed the workpiece underneath the upper blade guard, keeping it firmly pressed
against the fence. Allow the teeth to cut, and do not force the workpiece through the saw
blade. The saw blade speed should be kept constant.
8. Remember to use the push stick when close to the blade.
72
9. After completing the cut, switch the machine off, allow the saw blade to stop and remove
the workpiece.

WARNING:
• Never push or hold the free or cut-off side of the workpiece.
• Always use a push stick when ripping small workpieces.
Transporting (Fig. B)
1. To transport the saw, lower the head and depress the lock down pin
2. Lock the table 19 into lowest position. Lock the rail lock knob with the saw head in
the front position, lock the mitre arm in the far right mitre angle, slide the fence
completely inward and lock the bevel lever
to make the tool as compact as possible.
