General Handling; Sawing In Mitre Saw Mode - DeWalt DW743N QS Originalanweisungen

OPERATION
Instructions for Use
WARNING: Always observe the safety instructions and
applicable regulations.
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories.
WARNING:
• The attention of UK users is drawn to the "woodworking
machines regulations 1974" and any subsequent
amendments.
• 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.
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 (fi g. A1–A2, P)
This machine has two independent switching systems. In bench saw
mode, the on/off switch (1) (fig. A1) is used. In mitre saw mode, the
trigger switch (15) (fig. A2) is used.
BENCH SAW MODE (FIG. P)
The on/off switch used in bench saw mode offers multiple advantages:
– no-volt release function: should the power be shut off for some
reason, the switch has to be deliberately reactivated.
– extra safety: the hinged safety enclosure plate can be locked by
passing a padlock through the centre hasp. 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 (80).
To switch the machine off, press the red stop button (81).
MITRE SAW MODE (FIG. A2)
To switch the machine on, press the trigger switch (15).
To switch the machine off, release the trigger switch.
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.
Clamping the Workpiece (fi g. Q, R, S, X)
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 workpiece clamp to maintain
control and reduce the risk of personal injury and workpiece
damage.
Use the workpiece clamp (34) 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. The left side fence will slide from
side to side to aid in securing.
TO INSTALL CLAMP
1. Insert the workpiece clamp into the hole lateral to the mitre fence.
2. Rotate the clamp arm toward to the front of the mitre saw.
3. Loosen the knob to adjust the clamp up and down and secure it in
the choosen height.
4. 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.

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 moveable 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 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.
Vertical Straight Cross Cut (fi g. Q)
• Set the rotating table to 0° and make sure that the locating plunger
is engaged.
• Tighten the rotating table clamping knob.
• Place the wood to be cut against the fence. Take hold of the
control handle and press in the guard retraction lever.
• Switch the machine on.
• Allow the blade to cut freely. Do not force.
• After completing the cut, release the switch and wait for the saw
blade to come to a complete standstill before returning the head to
its upper rest position.
• Release the guard retraction lever.
WARNING: Do not allow the sawhead to jump back
unaided to prevent damage.
Mitre Cuts (fi g. R)
• Set the required mitre angle.
• Ensure that the rotating table clamp is tightly secured.
• Proceed as for a vertical straight cross-cut.
• Prevent the blade cutting the table if the angle is not 45°.
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 mitre, off-cut to the left.
Bevel Cuts (fi g. A2, S)
• Release the bevel clamp handle (22) and tilt the head to the angle
required.
• Tighten the bevel clamp handle.
• Proceed as for a vertical straight cross-cut.
Compound Mitre
This cut is a combination of a mitre and a bevel cut. The limitations are
35° mitre/30° bevel. Do not exceed these limits.
Set the bevel angle and subsequently set the mitre angle.
