To Make A Compound Miter Cut - Craftsman 315.212350 Operator's Manual

TO MAKE A COMPOUND MITER CUT
A compound miter cut is a cut made usinga 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 slopingsides, end for certain roof framfng outs.
To make this type of cut the control arm on the miter table
must be rotated to the correct angle and the sew arm
must be dited to the correct bevel angre, Care should
always be taken when making compound miter setups
due to the interactionof the two angle settings.
Adjustments of miter and bevel settingsare interde-
pendent with one another. Each time you adjust the miter
settingyou change the effect of the bevel sa_ng. Also,
each time you edlust the bevel setting you change the
effect of the miter settfng.
It may take several settings to obtain the desired cut. The
first angresetting should be checked after settingthe
second angle, since adjusting the second angle affects
the first.
Once the two correct settingsfor a particular cut have
been obtained, always make a test cut in scrap material
before makinga finish cut in good material.
• Pullout the lock pin and [fitsaw arm to its full height.
• Loosenthe miter lock handle.
• Lift the miter lock plate to disengage.
• Rotate the sew table untilthe pointer alignswith the
desired angle on the miter scale,
• Release the miter lock plate.
NOTE: You can quickly locate 0°, 15°, 22-1/2 °, 31.62°,
and 45 ° left or dght by releasingthe miter lock plate
as you rotate the control arm. The miter lock plate will
seat Itself In one of the positive stop notches, locateq
in miter table h'ame.
• Retightan the miter lock handle securely.
• Recheck miter angle setting.Make a test cut in scrap
material.
•PIsce the workplace flat on the rarer table with one
edge security againstthe fence. It the board is warped,
place the convex side against the fence. The concave
edge of a board could coffapea on the b_adeat the end
ofthe cul, jamming the blade.
• When cutting long pieces of lumber or molding, sup-
port the opposite end of the stock with a rollerstand or
with a work surface level with the saw table.
• ALign the cutting line on theworkpiece with the edge of
saw b_de.
• Grasp the stock firmly with one hand and secure it
against the fence or usethe optional work clamp or a
C-clamp to securethe workplace when possible.
_, WARNING: To avoid sedous personalinjury, always
keep hands away from cutting area. Never perform
any cutting opera_'onfreehand (wRhoutholding
workpieca against the fence), The brada could grab
the workpiece if it slipsor twists.
• 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.
• Grasp the saw handle firmly then squeeze the switch
trigger. Allow several seconds for the blade to reach
m_mum spewed.
• Slowly lower the blade into and through the workpiece,
• Release the switch trigger and allow the blade to stop
rotating before raising the blade out of workplace. Walt
u_til the e_ectdc b_ke stops blade from turning before
removing the won_pieee horn miter table.
_, WARNING: To avoid seriouspersonal lnju_/,always
tighten the miter lock handle securely before making
a out. Faiturato do so could resell Inmovement of
the control arm or miter table while making a cut.
• Adjustmentsof the miter fence mustbe made to cor-
respondto me desired angle of the bevel cut prior to
tilting the saw arm. The,fence Is marked for g°, 30 °, or
45 °, Loosenthe fence screw on the miter fence, slide
the fence to the desired position, and retightenthe
fence screw.
• The 45° triangle on the miter fence providesfor the
maximum clearance required for adjusting the miter
saw'sangle when making a bevel or compound cut.
• Loosenthe bevel lock knob and move the sew arm to
the left or right to the desired bevel angle.
• Bevel angles can be set from 0"to 45",
• Once the saw arm has been set at the dsaired angle,
securelytighten the bevel lock knob.
