Operation; Basic Saw Cuts - DeWalt D27105 Instruction Manual

E N G L I S H
• Tighten the knob (117).
• Check that the pointer (120) indicates zero on the scale (121).
Adjust if necessary.
Changing from saw bench to mitre saw mode (fi g. A3, E & M1)
• Remove the parallel fence (22), or the mitre fence, if fi tted (fi g. A3).
• Remove the upper blade guard (21).
• Replace the under-table guard (63) (fi g. E).
• Proceed as described in the section "Turning the sawhead and table
over".
• Slacken the riving knife clamp knob (97) and remove the riving knife (20),
while holding the blade guard (8) (fi g. M1).
• Lower the blade guard.
• Place the riving knife in its storage position in the inside of the base.

OPERATION

Instructions for Use
WARNING: Always observe the safety instructions and
applicable regulations.
• Ensure the material to be sawn is firmly secured in place.
• Apply only a gentle pressure to the tool and do not exert side
pressure on the saw blade.
• Avoid overloading.
The attention of UK users is drawn to the "woodworking machines
regulations 1974" and any subsequent amendments.
Ensure the machine is placed to satisfy your ergonomic conditions in terms
of table height and stability. The machine site shall be chosen so that the
operator has a good overview and enough free surrounding space around
the machine that allows handling of the workpiece without any restrictions.
To reduce effects of vibration make sure the environment temperature is not
too cold, machine and accessory is well maintained and the workpiece size
is suitable for this machine.
Prior to operation:
• Install the appropriate saw blade. Do not use excessively worn blades.
The maximum rotation speed of the tool must not exceed that of the
saw blade.
• Do not attempt to cut excessively small pieces.
• Allow the blade to cut freely. Do not force.
• Allow the motor to reach full speed before cutting.
• Make sure all locking knobs and clamp handles are tight.
Switching on and off (fi g. A1, R1 - R3)
This machine has two independent switching systems. In mitre saw mode,
the trigger switch (11) is used (fi g. R1). In saw bench mode, the on/off
switch (1) is used (fi g. R2). Integrated in the switch box is a motor overload
protector with manual reset. In case of a power shut-off, proceed as
follows:
- Make sure the machine has been switched off.
- Press the reset button (142).
Mitre saw mode (fi g. R1)
A hole (122) is provided in the trigger for insertion of a padlock to lock the
switch.
• To run the tool, press the trigger switch (11).
• To stop the tool, release the switch.
Saw bench mode (fi g. R2 & R3)
The on/off switch offers multiple advantages:
- no-volt release function: should the power be shut off for some reason,
the switch has to be deliberately reactivated.
20
- extra safety: the hinged safety enclosure plate (123) can be locked by
passing a padlock through the holes (124 & 125). The plate also serves
as an "easy to locate" emergency stop button as pressure on the front
of the plate will depress the stop button.
• To switch the machine on, press the green start button (126).
• To switch the machine off, press the red stop button (127).
Locking the switches
• In order to avoid unauthorised use of the machine, lock both switches
using padlocks.

Basic saw cuts

Sawing in mitre saw mode
It is dangerous to operate without guarding. Guards must be in position
when sawing.
• Make sure that the under-table guard does not become clogged with
sawdust.
• Always clamp the workpiece when cutting non-ferrous metals.
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 minimum length of offcut material is 10 mm.
- When cutting short material (min. 190 mm to the left or the right of the
blade), the use of the optional material clamp is recommended.
- When cutting UPVC sections, a supporting piece made out of timber
with a complementary profi le should be placed beneath the material
being cut to provide the correct level of support.
Vertical straight cross cut (fi g. S1)
• Loosen the mitre knob (79) and depress the mitre latch (80).
• Engage the mitre latch at the 0° position and tighten the mitre knob.
• Place the wood to be cut against the fence (7).
• Take hold of the operation handle (10) and press in the guard release
lever (9).
• Press the trigger switch (11) to start the motor.
• Depress the head to allow the blade to cut through timber and enter
the saw kerf (81).
• After completing the cut, release the switch and wait for the saw blade
to come to a complete stillstand before returning the head to its upper
rest position.
Vertical mitre cross-cut (fi g. S2)
• Loosen the mitre knob (79) and depress the mitre latch (80). Move the
rotating table left or right to the required angle.
• The mitre latch will automatically locate at 15°, 22.5°, 35.3° and 45°
both left and right. If any intermediate angle is required hold the head
fi rmly and lock by tightening the mitre knob.
• Always ensure that the mitre knob is locked tightly before cutting.
• 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,
right mitre,
Bevel cross-cut (fi g. A2, S3)
Bevel angles can be set from 48° left to 2° right and can be cut with the
rotating table set between zero and a maximum of 45° mitre position left
or right.
off-cut to the right
off-cut to the left.
