Blade Adjustment

Blade Alignment (Parallel to Mitre Slot) (Fig. F)

WARNING: Cut Hazard. Check the blade at 0˚ and 45˚
to make sure blade does not hit the throat plate, causing
personal injury.
If the blade appears to be out of alignment with the mitre slot
on the table top, it will require calibration for alignment. To
realign the blade and mitre slot, use the following procedure:

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. An accidental
start-up can cause injury.
1. Using a 5 mm hex wrench, loosen rear pivot bracket
fasteners 32 , located on the underside of the table, just
enough to allow the bracket to move side-to-side.
2. Adjust the bracket until the blade is parallel to the mitre
gauge slot.
3. Tighten the rear pivot bracket fasteners to 12.5–13.6 Nm.
Blade Height Adjustment (Fig. A)
The blade can be raised and lowered by turning the blade
height adjustment wheel 6 .
Make sure the top three teeth of the blade are just breaking
through the upper surface of the workpiece when sawing. This
will ensure that the maximum number of teeth are removing
material at any given time, thus giving optimum performance.
Aligning Guard Assembly to Blade (Fig. G)
1. Remove the throat plate. Refer to Removing Throat Plate
under Assembly and Adjustments.
2. Raise the blade to full depth of cut and 0° bevel angle.
3. Locate the three small set screws
used to adjust the riving knife position.
4. Lay a straight edge on the table against two blade tips. The
riving knife should not touch the straight edge.
5. If adjustment is needed, loosen the two larger lock
screws 34 .
6. Use the small set screws 33
position. Lay the straight edge on the opposite side of the
blade and repeat adjustments as needed.
7. Lightly tighten the two larger lock screws
8. Place a square flat against the riving knife to verify the riving
knife is vertical and in-line with the blade.
9. If needed, use the set screws to bring the riving knife vertical
with the square.
10. Repeat step 4 to verify position of riving knife. Repeat 5
through 9 if necessary.
11. Fully tighten the two larger lock screws
. These screws will be

Parallel Adjustment (Fig. A, H, I)
For optimum performance, the blade must be parallel to the
rip fence. This adjustment has been made at the factory. To
re-adjust:
Position 1 Fence Alignment
1. Install the fence in position 1 and unlock the rail lock
lever . Locate both locator pins
5
on the front and rear rails.
2. Loosen the rear locator pin screw and adjust the allignment
of the fence in the groove until the fence face is parallel to
the blade. Make sure you measure from the fence face to
the front and back of the blade to ensure alignment.
3. Tighten the locator screw and repeat on the left side of
the blade.
4. Check rip scale pointer adjustment (Fig. I).
Position 2 Fence Alignment (Fig. H)
1. To align position 2 fence locator pins
position 1 pins have been aligned, refer to Position 1
Fence Alignment.
2. Loosen the position 2 pins, then using the holes on the
blade wrench 19 as a guide for positioning, align the
pins (Fig. H).
3. Tighten the locator pins (front and rear).
Adjusting the Rip Scale (Fig. H, I)
1. Unlock the rail lock lever
5
2. Set the blade at 0° bevel and move the fence in until it
touches the blade.
3. Lock the rail lock lever.
4. Loosen the rip scale indicator screws
scale indicator to read zero (O). Retighten the rip scale
indicator screws. The yellow rip scale (top) reads correctly
only when the fence is mounted on the right side of the
blade and is in position 1
47
not the 610 mm rip position. The white scale (bottom)
reads correctly only when the fence is mounted on the
right side of the blade and in position 2
610 mm ripping).
The rip scale reads correctly only when the fence is mounted to
the right of the blade.
Rail Lock Adjustment (Fig. I, J)
The rail lock has been factory-set. If you need to re-adjust,
proceed as follows:
1. Lock the rail lock lever .
5
2. On the underside of the saw, loosen the jam nut
3. Tighten the hex rod 37 until the spring on the locking
system is compressed creating the desired tension on the
rail lock lever. Retighten the jam nut against the hex rod.
4. Flip the saw over and check that the fence does not move
when the lock lever is engaged. If the fence is still loose,
tighten the spring further.
