Prior To Operation - DeWalt DW712 Handbuch

EN G LI S H
• To override the bevel stops, first release the saw head and push
it slightly to the left, then pull out the override knob (27) and turn
it into the override position (62). The override knob automatically
clicks in place.
• Set the required bevel angle and secure the head in this position.
• To discontinue the override, turn the override knob (27) back into
the bevel stop position (61).
CHECKING AND ADJUSTING THE BEVEL ANGLE (FIG. A1, A2 & I5)
• Make sure the override knob (27) is located in the bevel stop
position.
• Loosen the left side fence clamping knob (29) and slide the upper
part of the left side fence to the left as far as it will go.
• Loosen the bevel clamp handle (11) and move the saw head to the
left. This is the 45° bevel position.
• If adjustment is required, proceed as follows:
• Turn the stop screw (9) in or out as necessary until the pointer (58)
indicates 45°.
RAIL GUIDE ADJUSTMENT (FIG. L)
• Regularly check the rails for clearance.
• To reduce clearance, gradually rotate the set screw (64) clockwise
while sliding the saw head back and forth.
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.
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.
• Secure the workpiece.
• Although this saw will cut wood and many nonferrous materials,
these operating instructions refer to the cutting of wood only. The
same guide-lines apply to the other materials. Do not cut ferrous
(iron and steel) materials, fibre cement or masonry with this saw!
• Make sure to use the kerf plate. Do not operate the machine if the
kerf slot is wider than 10 mm.
Switching On and Off (fi g. M)
A hole (65) is provided in the trigger for insertion of a padlock to lock the
tool.
• To run the tool, press the on/off switch (1).
• To stop the tool, release the switch.
32
Setting the Variable Speed (fi g. M)
DW712
The speed control dial (19) can be used for advance setting of the
required range of speed.
• Turn the dial button (19) to the desired range, which is indicated
by a number.
• Use high speeds for sawing soft materials such as wood. Use low
speeds for sawing metal.
Basic Saw Cuts
VERTICAL STRAIGHT CROSS CUT (FIG. A1, A2 & N)
• Release the mitre lever (4) and depress the mitre latch (5).
• Engage the mitre latch at the 0° position and tighten the mitre lever.
• Place the wood to be cut against the fence (3 & 7).
• Take hold of the operating handle (18) and depress the head lock
up release lever (17) to release the head. Press the trigger switch
(1) to start the motor.
• Depress the head to allow the blade to cut through the timber and
enter the plastic kerf plate (31).
• 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.
PERFORMING A SLIDING CUT (FIG. O)
The guide rail allows cutting larger workpieces from 50 x 100 mm up to
500 x 1000 mm using an out-down-back sliding motion.
• Release the rail lock knob (13).
• 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.
• 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.
VERTICAL MITRE CROSS-CUT (FIG. A1, A2 & P)
• Release the mitre lever (4) and depress the mitre latch (5). Move the
arm left or right to the required angle.
• 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.
• Always ensure that the mitre lever 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; i.e. left mitre, off-cut to the right - right mitre, off-cut
to the left.
BEVEL CUTS (FIG. A1, A2 & Q)
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.
• Loosen the left side fence clamping knob (29) and slide the upper
part of the left side fence (3) to the left as far as it will go. Loosen
the bevel clamp handle (11) and set the bevel as desired.
• Tighten the bevel clamp handle (11) firmly.
• Proceed as for a vertical straight cross-cut.
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.
