ASSEMBLY
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.
MOUNTING THE SAW BLADE (FIG. E1–E5)
• Never depress the spindle lock button while the blade is
under power or coasting.
• Do not cut light alloy and ferrous metal (containing iron or
steel) or masonry or fibre cement product with this mitre
saw.
• Depress the head lock up release lever (17) to release
the lower guard (2), then raise the lower guard as far as
possible.
1. With the lower guard held in the raised position by the guard
bracket screw (43), depress the spindle lock button (16) with one
hand, then use the supplied blade spanner (26) in the other hand to
loosen the left-hand threaded blade locking screw (45) by turning
clockwise.
WARNING! To use the spindle lock, press the button as
shown and rotate the spindle by hand until you feel the lock
engage.
Continue to hold the lock button in to keep the spindle from
turning.
2. Remove the blade locking screw (45) and the outside arbor collar
(46).
3. Install the saw blade (47) onto the shoulder (48) provided on the
inside arbor collar (49), making sure that the teeth at the bottom
edge of the blade are pointing toward the back of the saw (away
from the operator).
4. Replace the outer arbor collar (46).
5. Tighten the blade locking screw (45) 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.: DT4320 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 (FIG. F1–F4)
• Release the mitre lever (4) and depress the mitre latch (5) to release
the mitre arm (50).
• 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 (51).
• Place a square (52) against the left side (3) of the fence and blade
(47) (fig. F3).
WARNING: Do not touch the tips of the blade teeth with
the square.
• If adjustment is required, proceed as follows:
• Loosen the screws (53) 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 (53). Pay no attention to the reading of the
mitre pointer at this point.
ADJUSTING THE MITRE POINTER (FIG. F1, F2 & G)
• Release the mitre lever (4) and depress the mitre latch (5) to release
the mitre arm (50).
• Move the mitre arm to set the mitre pointer (54) to the zero
position, as shown in fig. G.
• With the mitre lever loose, allow the mitre latch to snap into place
as you rotate the mitre arm past zero.
• Observe the pointer (54) and mitre scale (6). If the pointer does not
indicate exactly zero, loosen the screw (55), move the pointer to
read 0° and tighten the screw.
MITRE LOCK/DETENT ROD ADJUSTMENT (FIG. H)
If the base of the saw can be moved while the mitre lever (4) is locked,
the mitre lock/detent rod (56) must be adjusted.
• Unlock the mitre lever (4).
• Fully tighten the mitre lock/detent rod (56) using a screwdriver (57).
Then loosen the rod a quarter of a turn.
• Check that the table does not move when the lever (4) is locked at
a random (not preset) angle.
CHECKING AND ADJUSTING THE BLADE TO THE TABLE (FIG. I1–I4)
• Loosen the bevel clamp handle (11).
• Press the saw head to the right to ensure it is fully vertical and
tighten the bevel clamp handle.
• Pull down the head until the blade just enters the saw kerf (51).
• Place a set square (52) on the table and up against the blade (47)
(fig. I2).
WARNING: Do not touch the tips of the blade teeth with
the square.
• If adjustment is required, proceed as follows:
• Loosen the bevel clamp handle (11) and turn the vertical position
adjustment stop screw (28) in or out until the blade is at 90° to the
table as measured with the square.
• If the bevel pointer (58) does not indicate zero on the bevel scale
(10), loosen the screw (59) that secures the pointer and move the
pointer as necessary.
ADJUSTING THE FENCE (FIG. J1, J2)
The upper part of the left side of the fence can be adjusted to the left to
provide clearance, allowing the saw to bevel to a full 48° left. To adjust
the fence (3):
• Loosen the plastic knob (29) 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.
WARNING: The guide groove (60) can become clogged
with sawdust. Use a stick or some low pressure air to clear
the guide groove.
The moveable part of the right side of the fence can be adjusted to
provide maximum support of the workpiece near the blade, while
allowing the saw to bevel to a full 45° left. The sliding distance is limited
by stops in both directions.
To adjust the fence (8):
• Loosen the wing nut (76) to release the fence (8).
• 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 wing nut (76) to secure the fence in place.
OVERRIDING THE BEVEL STOPS (FIG. K)
The bevel stops facilitate the setting of the saw blade in the vertical
position and the 45° bevel position. By overriding the bevel stops, bevel
angles can be achieved from 2° right to 48° left.
