n Grasp the saw handle firmly then squeeze the switch
trigger. Allow several seconds for the blade to reach
maximum speed.
n Slowly lower the blade into and through the workpiece.
n Release the switch trigger and allow the saw blade to
stop rotating before raising the blade out of workpiece.
Wait until the electric brake stops blade from turning
before removing the workpiece from miter table.
TO COMPOUND MITER CUT
A compound miter cut is a cut made using a miter angle
and a bevel angle at the same time. This type of cut is
used to make picture frames, cut molding, make boxes
with sloping sides, and for certain roof framing cuts.
To make this type of cut the control arm on the miter table
must be rotated to the correct angle and the saw arm
must be tilted to the correct bevel angle. Care should
always be taken when making compound miter setups
due to the interaction of the two angle settings.
Adjustments of miter and bevel settings are interde-
pendent with one another. Each time you adjust the miter
setting you change the effect of the bevel setting. Also,
each time you adjust the bevel setting you change the
effect of the miter setting.
It may take several settings to obtain the desired cut. The
first angle setting should be checked after setting the
second angle, since adjusting the second angle affects
the first.
Once the two correct settings for a particular cut have
been obtained, always make a test cut in scrap material
before making a finish cut in good material.
TO MAKE A COMPOUND CUT
n Pull out the lock pin and lift saw arm to its full height.
n Loosen the miter lock handles.
n Rotate the saw table until the pointer aligns with the
desired angle on the miter scale.
n Retighten the miter lock handles securely.
OPERATION
WARNING:
tighten the miter lock handle securely before making
a cut. Failure to do so could result in movement of
the control arm or miter table while making a cut.
n Loosen the bevel lock knob and move the saw arm to
the left to the desired bevel angle.
n Bevel angles can be set from 0˚ to 45˚.
n Once the saw arm has been set at the desired angle,
securely tighten the bevel lock knob.
BEVEL CUT
n Recheck miter angle setting. Make a test cut in scrap
material.
n Place the workpiece flat on the miter table with one
edge securely against the fence. If the board is warped,
place the convex side against the fence. If the concave
edge of a board could collapse on the blade at the end
of the cut, jamming the blade.
n When cutting long pieces of lumber or molding, sup-
port the opposite end of the stock with a roller stand or
with a work surface level with the saw table.
n Align the cutting line on the workpiece with the edge of
saw blade.
n Grasp the stock firmly with one hand and secure it
against the fence or use the optional work clamp or a
C-clamp to secure the workpiece when possible.
NOTE: When making a 45˚ left miter and a bevel angle
greater than 30˚, you must use a C-clamp to secure the
Fig. 34
workpiece or move clamp to the right side of the base.
WARNING:
keep hands away from cutting area. Never perform
any cutting operation freehand (without holding
workpiece against the fence). The blade could grab
the workpiece if it slips or twists.
n Before turning on the saw, perform a dry run of the cut-
ting operation just to make sure that no problems will
occur when the cut is made.
