Assembly
Prior to assembly always unplug the tool.
The motor and guards are already assembled onto the base.
Stabilizer (fig. C)
Your saw includes one base stabilizer (10).
Insert the stabilizer into the holes (27).
Move the stabilizer in or out until it contacts the work surface.
Tighten the screws (28).
Never use your saw without the stabilizer.
Bench mounting (fig. A2)
Holes (8) are provided in all four feet to facilitate bench mounting.
Two different sized holes are provided to accommodate different sizes
of bolts. Use either hole; it is not necessary to use both. Always mount
your saw firmly to prevent movement. To enhance the portability,
the tool can be mounted to a piece of 12.5 mm or thicker plywood
which can then be clamped to your work support or moved to other
job sites and reclamped.
When mounting your saw to a piece of plywood, make sure that the
mounting screws do not protrude from the bottom of the wood.
The plywood must sit flush on the work support. When clamping the
saw to any work surface, clamp only on the clamping bosses where
the mounting screw holes are located. Clamping at any other point will
interfere with the proper operation of the saw.
To prevent binding and inaccuracy, be sure the mounting surface is not
warped or otherwise uneven. If the saw rocks on the surface, place a
thin piece of material under one saw foot until the saw is firm on the
mounting surface.
Mounting the saw blade (fig. A1, A2, D1 & D2)
The teeth of a new blade are very sharp and can be
dangerous.
Lock the mitre lever (4), the rail lock knob (20) and the bevel
lever (11) (fig. A1 & A2).
Depress the head lock up release lever (50) to release the lower guard
(2), then raise the lower guard as far as possible.
Loosen the upper guard cover screw (29) and pivot the upper guard (30) up.
Never replace the screw (29) with a different screw!
Hold the guard up, press the spindle lock button (26) (fig. D2) and
loosen the blade screw (31) by turning clockwise using the saw blade
wrench (fig. D1).
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 (fig. D2).
Remove the blade screw (31) and the outer flange (32) (fig. D1).
Install the saw blade (33) onto the inner flange making sure that the
teeth at the bottom edge of the blade are pointing toward the back of
the saw (away from the operator).
Replace the outer flange (32).
Tighten the blade locking screw (31) by turning counter-clockwise while
holding the lower guard up and the spindle lock engaged with your
other hand.
Never press the spindle lock while the blade is rotating.
Adjustment
Prior to adjustment always unplug the tool.
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. E)
Loosen the mitre lever (4) and squeeze the mitre latch (5) upwards to
release the scale/mitre arm assembly (34).
Swing the mitre arm until the latch locates it at the 0° mitre position.
Do not tighten the lever (4).
Pull down the head until the blade just enters the saw kerf (35).
Place a square (36) against the lower part (37) of the fence (7) and
blade (33).
Do not touch the tips of the blade teeth with the square.
If adjustment is required, proceed as follows:
Loosen the four screws (38) and move the scale/mitre arm assembly (34)
left or right until the blade is at 90° to the fence as measured with
the square.
Retighten the four screws (38). Pay no attention to the reading of the
mitre pointer at this point.
Adjusting the mitre pointer (fig. F)
Loosen the mitre lever and squeeze the mitre latch to release the
scale/mitre arm assembly (34).
Move the saw arm to set the mitre pointer (39) to the zero position.
With the mitre clamp knob loose, allow the mitre latch to snap into
place as you rotate the mitre arm past zero.
Observe the pointer (39) and mitre scale (6). If the pointer does not
indicate exactly zero, loosen the screw (40) and gently move the
pointer left or right.
Retighten the screw (40).
Mitre lock/detent rod adjustment (fig. G)
If the base of the saw can be moved while the mitre lever (4) is locked,
the mitre lock/detent rod (41) should be adjusted.
Unlock the mitre lever (4).
Fully tighten the mitre lock/detent rod (41) by turning it clockwise using
a screwdriver (42). Turn counterclockwise 1/4 of a turn.
Check that the table will not rotate when the lever (4) is locked at a
random (not preset) angle.
