3. Raise the lower clear plastic blade guard (1) to the
uppermost position. (Fig. 24)
4. While holding the lower blade guard, loosen the cover
plate screw (2) with a Phillips screwdriver.
5. Rotate the cover plate (3) to expose the arbour bolt (4).
6. Place the blade end wrench over the arbour bolt
7. Locate the arbour lock (5) on the motor, below the belt
cover. (Fig. 25)
8. Press the arbour lock, holding it in firmly while turning the
blade clockwise. The arbour lock will then engage and
lock the arbour. Continue to hold the arbour lock, while
turning the wrench clockwise to loosen the arbour bolt.
9. Remove the arbour bolt (5), the laser collar (6), and the
blade (7). Do not remove the inner blade collar. (Fig. 26)
10. Raise the lower clear plastic blade guard (1) to the
upright position (Fig. 24) to remove the blade.
NOTE: Pay attention to the pieces removed, noting their
position and direction they face. Wipe the blade collars clean
of any sawdust before installing a new blade. Also, the
304.8mm blade has a 25.4mm arbour hole with a 15.875mm
reducer to mount onto the saw.
Installing Blade
Un-plug the mitre saw before changing/installing the blade.
1. Install a 305 mm blade with a 16 mm arbour (or a 25.4
mm arbour with a 16 mm reducer) making sure the
rotation arrow on the blade matches the clockwise rotation
arrow on the upper guard, and the blade teeth are pointing
downward.
2. Place the laser collar (4) against the blade and on the
arbour. Thread the arbour bolt (4) on the arbour. (Fig. 26)
in a counterclockwise direction.
IMPORTANT: Make sure the flats of the blade collars are
engaged with the flats on the arbour shaft. Also, the flat-side
of the laser collar must be placed against the blade.
3. Place the blade wrench on the arbour bolt.
4. Press the arbour lock (5), holding it in firmly while turning
the blade counterclockwise. When it engages, continue
to press the arbour lock in, while tightening the arbour
bolt (4) securely. (Fig. 25)
5. Rotate the cover plate (3) back to its original position
until the slot in the cover plate engages with the cover
plate screw (2). While holding the lower blade guard,
tighten the screw with a Phillips screwdriver. (Fig. 25)
NOTE : The lower blade guard must be raised to the
upright position to access the cover plate screw.
6. Lower the clear retractable blade guard (1) and verify the
operation of the guard does not bind or stick. (Fig. 24)
7. Be sure the arbour lock is released so the blade
turns freely by spinning the blade until the arbour lock
disengages.
NOTE : Make sure the collars are clean and properly
arranged. Lower the blade into the lower table and check for
any contact with the base or the turn table by spinning the
blade manually.
Setting Cutting Depth (Fig. 23)
The depth of cut can be preset for even and repetitive
shallow cuts.
1. Adjust the cutting head down until the teeth of the blade
are at the desired depth of cut.
2. While holding the upper arm in position, turn the stop
knob (1) until it touches the stop plate (2).
3. Recheck the blade depth by moving the cutting head
front to back through the full motion of a typical cut along
the control arm.
The Arbour Laser Guide
Your tool is equipped with our latest innovation, the
Arbour Laser Guide, a battery powered device using
Class 1M laser beams. The laser beams will enable you
to preview the mitre blade path on the workpiece to be
cut before you begin your operation.
DANGER : Laser is activated when blade is rotating.
Do not stare into beam or view directly with optical
instruments. Do not remove the warning label affixed
to the blade guard. Avoid direct eye contact with light
source.
NOTE : The red laser line will appear as a dotted line when
the motor is activated and the blade assembly is in the
uppermost position. This broken line will assist you in aligning
the mark on your workpiece with the cutting path of the saw
blade. As you lower the blade assembly, the retractable guard
will lift and turn the broken line into a solid red laser line.
Laser Warning Label: Laser radiation do not view directly
with optical instruments class 1M laser product <0.39mW,
400-700nm, CW, Acc.IEC 60825-1:2007
OPERATION OF LASER
With the blade assembly in the uppermost position:
1. Position your workpiece onto the mitre saw.
2. Turn on the mitre saw to activate the laser beam.
3. Verify the laser beam is aligned with the mark on the
workpiece ( WARNING : Do not lower the blade assembly
during the alignment process).
4. If the mark on the workpiece is not aligned with the dotted
laser line, turn off machine, wait for the blade to stop and
reposition workpiece.
5. Turn on the mitre saw and verify alignment.
6. Once alignment is achieved, secure workpiece with a
clamping device and perform the cut.
Changing Blades (Fig. 24, 25, 26)
WARNING: To avoid injury from accidental starting,
always turn the switch off and remove the power plug
from the power source before changing the blades.
Use correctly sharped saw blades. Observe the maximum
speed and tooth type marked on the saw blade. Blade
replacement procedure including the method for
repositioning that this must be carried out correctly. Do
not use a saw blade which is not recommended in this
owner’s manual.
Removing the Blade
1. Unplug the saw from the outlet
2. Raise the mitre saw to the upright position.
