OPERATION

Instructions for Use
WARNING: Always observe the safety instructions and
applicable regulations.
WARNING: To reduce the risk of injury, turn unit off and
disconnect machine from power source before installing
and removing accessories, before adjusting or changing
set-ups or when making repairs. Be sure the trigger switch
is in the OFF position. An accidental start-up can cause injury.
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.
Switching on and off (fig. O)
The on/off switch has a built-in no-volt release function: should the power be
shut off for some reason, the switch has to be deliberately reactivated.
• To switch the machine on, press the green start button (71).
• To switch the machine off, press the red stop button (72).
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 (27) 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)
• Release the mitre lever (10) and depress the mitre latch (9).
• Engage the mitre latch at the 0° position and tighten the mitre lever.
• Place the wood to be cut against the fence (6 & 13).
• Take hold of the operating handle (2) and depress the head lock up
release lever (3) to release the head.
• Switch the machine on and allow the saw blade to reach full speed.
• Depress the head to allow the blade to cut through the timber and enter
the plastic kerf plate (8).
• 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 (fi g. Q)
The guide rail allows cutting larger workpieces using an out-down-back
sliding motion.
• Release the rail lock knob (18).
• Pull the saw head towards you and switch the tool on.
• Lower the saw blade into the workpiece and push the head back to
complete the cut.
