5. Tighten the blade locking screw (37) carefully by turning counter-
clockwise while holding the spindle lock engaged with your other hand.
WARNING! Be aware the saw blade shall be replaced in the
described way only. Only use saw blades as specified under
Technical Data; Cat. no.: DT4330 is suggested.
Adjustment
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.
Your mitre saw was accurately adjusted at the factory. If readjustment due
to shipping and handling or any other reason is required, follow the steps
below to adjust your saw. Once made, these adjustments should remain
accurate.
Checking and adjusting the blade to the fence (fi g. E1 - E4)
• Release the mitre lever (4) and depress the mitre latch (5) to release the
mitre arm (42).
• Swing the mitre arm until the latch locates it at the 0° mitre position.
Do not tighten the lever.
• Pull down the head until the blade just enters the saw kerf (43).
• Place a square (44) against the left side of the fence (3) and blade (39)
(fi g. E3).
WARNING: Do not touch the tips of the blade teeth with the
square.
• If adjustment is required, proceed as follows:
• Loosen the screws (45) and move the scale/mitre arm assembly left or
right until the blade is at 90° to the fence as measured with the square.
• Retighten the screws (45). Pay no attention to the reading of the mitre
pointer at this point.
Adjusting the mitre pointer (fi g. E1, E2 & F)
• Release the mitre lever (4) and depress the mitre latch (5) to release the
mitre arm (42).
• Move the mitre arm to set the mitre pointer (46) to the zero position,
as shown in fi g. F.
• With the mitre lever loose, allow the mitre latch to snap into place as
you rotate the mitre arm past zero.
• Observe the pointer (46) and mitre scale (7). If the pointer does not
indicate exactly zero, loosen the screw (47), move the pointer to read
0° and tighten the screw.
Mitre lock/detent rod adjustment (fi g. G)
If the base of the saw can be moved while the mitre lever (4) is locked,
the mitre lock/detent rod (48) must be adjusted.
• Unlock the mitre lever (4).
• Loosen the lock nut (61) on the miter lock rod.
• Fully tighten the mitre lock/detent rod (48) using a screwdriver.
Then loosen the rod one turn.
• Check that the table does not move when the lever (4) is locked at
a random (not preset) angle.
• Tighten lock nut (61).
Checking and adjusting the blade to the table (fi g. H1 - H4)
• Loosen the bevel clamp handle (21) and lift the bevel latch (20) to
release the saw arm.
• Move the saw arm until the latch locates it at the 0° bevel position.
Do not tighten the handle.
• Pull down the head until the blade just enters the saw kerf (43).
• Place a set square (44) on the table and up against the blade (39) (fi g. H2).
WARNING: Do not touch the tips of the blade teeth with the
square.
• Block the head saw down with the pin (22).
• If adjustment is required, proceed as follows:
• Loosen the nuts (49, 55) and move the saw arm assembly left or right
until the blade is at 90° to the table as measured with the square.
Retighten the nut (49). The bevel angle requires adjustment after the
blade to table adjustment is complete.
• Adjust the left and right bevel angles.
• If the bevel pointer (50) does not indicate zero on the bevel scale (15),
loosen the screw (51) that secures the pointer and move the pointer as
necessary. Repeat as for the bevel pointer located on the opposite side.
Adjusting the fence (fi g. I1 & I2)
The upper part of the fence can be adjusted to provide clearance, allowing
the saw to bevel to a full 48° both left and right.
To adjust the left fence (3):
• Loosen the plastic knob (52) and slide the fence to the left.
• Make a dry run with the saw switched off and check for clearance.
Adjust the fence to be as close to the blade as practical to provide
maximum workpiece support, without interfering with the up and down
movement of the arm.
• Tighten the knob securely.
To adjust the right fence (8):
• Loosen the plastic knob (53) and slide the fence to the right.
• Proceed as for adjusting the left fence.
WARNING: The guide grooves (54) can become clogged with
sawdust. Use a stick or some low pressure air to clear the guide
grooves.
Checking and adjusting the bevel angle (fi g. A2, I1, I2, J1 & J2)
Checking and adjusting the left bevel angle
• Loosen the left side fence clamping knob (52) and slide the upper part
of the left side fence to the left as far as it will go.
• Loosen the bevel clamp handle (21) and lift the bevel latch (20) to
release the saw arm.
• Move the saw arm to the left until the latch locates it at the 45° bevel
position. Do not tighten the handle.
• Check that the bevel indicator (50) indicates 45° on the bevel scale (15)
(fi g. J1).
• If adjustment is required, proceed as follows:
• Loosen the nut (55) and turn the stopscrew (56) in or out as necessary
until the pointer (50) indicates 45°. Retighten the nut (55).
• To achieve a 50° bevel, turn the screw on the angle position stop out to
allow the saw arm to move as necessary.
Checking and adjusting the right bevel angle
• Loosen the right side fence clamping knob (53) and slide the upper
part of the right side fence to the left as far as it will go.
• Loosen the bevel clamp handle (21) and lift the bevel latch (20) to
release the saw arm.
• Move the saw arm to the right until the latch locates it at the 45° bevel
position. Do not tighten the handle.
• Check that the bevel indicator (50) indicates 45° on the bevel scale (15)
(fi g. J2).
• If adjustment is required, proceed as for adjusting the left bevel angle.
Adjusting the bevel clamping system (fi g. K)
If the saw arm can be moved when the bevel clamp handle (21) is locked,
the clamping sytem must be adjusted.
• Remove the screw (56) holding the handle.
• Lift off the handle and turn it 1/8 turn clockwise. Refi t the screw.
• Check that the saw arm does not move when the bevel clamp handle
(21) is locked at a random (not preset) angle.
