Once made, these adjustments should remain accurate. Take a little time now to follow
these directions carefully to maintain the accuracy of which your saw is capable.
RAIL LOCK ADJUSTMENT
(Tightening Fence Clamping System)
1. Lock the rail lock lever (W).
2. On the underside of the saw, loosen the nut (LL) (Fig. 18).
3. Tighten the hex rod (MM) 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.
RIP SCALE ADJUSTMENT
(Calibrating Rip Scale)
1. Unlock the rail lock lever (W).
2. Set the blade at 0° bevel and move the
fence until it is flush with the blade.
3. Lock the rail lock lever.
4. Loosen the screws (NN, Fig. 16) in
the rip scale pointer with a Phillips
screwdriver and reset the red line to 0°
on the scale.
5. Tighten the screws back into the rail.
NOTE: The rip scale only reads correctly
when the fence is mounted on the right side
of the blade.
BLADE ALIGNMENT ADJUSTMENT
(Blade Parallel to Miter Slot)
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 miter slot on the table top, it will
require calibration for alignment. To realign
the blade and miter slot, use the following
procedure:
1. Locate the black Allen locator screws
(OO) that hold up the trunnion to the
bottom of the table in the rear of the saw.
2. Loosen both screws and align the blade
with the miter slot. Be sure to measure
between the miter slot and the back and
front of the blade to ensure parallelism.
3. Snugly tighten the screws to secure the
trunnion and blade assembly to the table
at the parallel position.
FENCE ALIGNMENT ADJUSTMENT
(FIG. 4, 5) (Blade Parallel to Fence)
If you experience fence alignment problems and want to correct an out of parallel between
the fence and the blade, be sure to check the alignment of the blade to the miter slot first.

After confirming that those elements are aligned, proceed with alignment of the blade to the
fence using the following procedure:
1. Unlock the rail lock lever (W) and locate the two fence locator screws (AA) that support
the fence on the front and rear rails.
2. Loosen the rear locator screw and adjust the position of the fence in the groove on the
fence until it sets the fence face 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 adjustment.
BEVEL STOP AND POINTER ADJUSTMENT
(Calibrating Bevel Scale)
Calibrating the bevel system on the saw may require two separate steps, one for the bevel
scale and another for the bevel pointer. The scale should always be checked first followed
by adjustments to the red pointer.
BEVEL LOCK ADJUSTMENT (FIG. 21)
The bevel lock lever (J) may need adjustment to maintain lock force.
To do this, put the lock lever in the locked position. Use a Phillips screwdriver to remove the
screw (PP) holding the lock lever in place (Fig. 21). Remove the lock lever from the locking
bolt and place lock lever in the desired position. Insert the screw (PP) and tighten securely.
FIG. 21
Part A – Adjusting the Bevel Scale System (Fig. 22, 23)
1. Remove the Blade guard assembly from the saw and raise the blade all the way up in
the table.
2. Unlock the bevel lock lever (J) and loosen the bevel stop screw (QQ).
3. Place a square against the table and blade.
NOTE: Be sure to place the square between the teeth on the blade to ensure an
accurate measurement.
4. Adjust the bevel angle until the blade is flat against the square. Lock the bevel lock
lever (J).
5. Move the bevel stop cam (RR) until it firmly contacts the trunnion casting. Tighten the
bevel stop screw.
6. Repeat procedure at 45˚ using a triangle or speed square.
Part B – Adjusting the Bevel Scale Pointer
NOTE: Complete this step only if Part A has been completed.
7. Check the bevel scale angle. If the pointer does not read 0°, loosen the pointer screw
(SS) and move it to the 0° mark on the bevel scale. Retighten the pointer screw.
