Adjusting The Miter Saw; Adjusting The 0° Miter Angle - Performax 240-3690 Owner's Manual

Before making any cuts, it is important to check
all adjustments to make sure the saw will
function properly and cut at the proper angles.
The following adjustments must be checked and
appropriate adjustments made before using the
miter saw.
! WARNING:
Remove the plug from the
power source before checking or making
any adjustments. Failure to remove the plug
could result in serious personal injury as a
result of the miter saw starting unexpectedly.
ADJUSTING THE 0° MITER ANGLE
The 0° miter angle is preset at the factory.
However, should it become necessary to reset,
Follow these procedures:
1. Turn the miter locking knob (1) counter
clockwise 2 turns (Fig. 7).
2. Squeeze the miter detent locking lever (2)
and move the miter arm (3) left or right until
the 0° pointer (4) lines up with the 0° line
on the scale.
3. Release the miter detent locking lever and
once again move the miter arm back and
forth until the detent lock drops into the
matching notch (5) in the bottom of the
base.
4. If the 0° pointer is not aligned directly with
the 0° line on the scale, use a #2
screwdriver to loosen the pointer screw (6).
Then align the pointer with the 0° line on
the scale and tighten the screw to hold the
pointer firmly in place.

Once steps #1 through #5 have been
completed, it is important to verify that the 0°
settings are accurate and that the blade is
perpendicular to the fence as follows:
5. Lock the handle in the down position. Hold
a combination square (not provided) (7)
against the fence (8) and beside the saw
blade (9) (Fig. 8).
NOTE: Make sure the square rests against
the body of the blade without touching the
carbide tips or teeth. When properly
positioned, the full length of the
combination square should contact both
the saw blade and the fence. If the saw
blade does not contact the full length of the
combination square, adjust the fence as
follows:
6. Loosen the four fence adjustment screws
(10) using the 6 mm hex key (Fig. 9).
7. Hold the combination square against the
saw blade. Gently tap the lower edge the
fence with a plastic mallet until it contacts
the full length of the combination square.
8. Tighten the fence adjustment screws and
re-check the fence alignment.
