Compound Cut - Ryobi EMS-1422L Owner's Operating Manual

OPERATING YOUR MITRE SAW
■ Once the handle has been set at the desired angle,
securely tighten the bevel lock knob (20).
■ Place the workpiece flat on the mitre 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 the board is placed against the
fence, the board could collapse on the blade at the
end of the cut, jamming the blade.
■ When cutting long pieces of timber or molding, support
the overhanging end(s) of the stock.
■ Align the cutting line on the workpiece with the edge
of saw blade.
■ Grasp the stock firmly and secure it against the fence.
■ Before turning on the saw, perform a dry run of the
cutting operation just to make sure that no problem
will occur when the cut is made.
■ Grasp the handle firmly, then squeeze the switch
trigger. Allow several seconds for the blade to reach
maximum speed.
■ Use thumb to press the safety lock toward the handle.
■ Slowly lower the blade into and through the
workpiece.
■ Release trigger switch and allow the saw blade to stop
rotating before raising the blade out of workpiece.
■ Slowly move the blade upward to the highest position
and release the safety lock.

COMPOUND CUT

A compound cut is a cut made using a mitre angle and
a bevel angle at the same time. This type of cut is used
to make picture frames, cut moulding, make boxes with
sloping sides, and for certain roof framing cuts.
To make this type of cut the mitre 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 mitre setups due to the interaction of
the two angle settings.
Adjustments of mitre and bevel settings are
interdependent with one another. Each time you adjust
the mitre setting you change the effect of the bevel
setting. Also, each time you adjust the bevel setting you
change the effect of the mitre 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 wood
before making a finish cut in good wood. (fig. 22)

TO MAKE A COMPOUND CUT WITH YOUR MITRE
SAW
■ Pull out the lock pin and lift the saw arm to its full
height.
■ Loosen the mitre lock lever .
■ Rotate the mitre table until the pointer aligns with the
desired angle on the mitre scale and securely lock the
mitre table.
Note: You can quickly locate 5° left or right on the
scale. The mitre table can be seated in one of the
positive stop notches, located in the mitre table frame.
WARNING: To avoid serious personal injury, always
lock the mitre table before making a cut. Failure to do so
could result in movement of the mitre table while making
a cut.
■ Loosen the bevel lock knob and move the handle to
the desire bevel angle.
■ Bevel angles can be set from L45deg to R10deg.
■ Align the indicator point with the desired angle.
■ Once the handle has been set at the desired angle,
securely tighten the bevel lock lever.
■ Recheck mitre angle setting. Make a test cut in a
scrap material.
■ Place the workpiece flat on the mitre table with one
edge securely against the fence. If the material is
warped then place the convex edge of the work piece
against the fence.
If the concave edge of the board is placed against the
fence, the board could collapse on the blade at the
end of the cut, jamming the blade.
■ When cutting long pieces of timber or molding, support
the opposite end of the stock with a roller stand or with
work surface level with the saw table.
■ Align the cutting line on the workpiece with the edge
of the saw blade.
■ Grasp the stock firmly and secure it against the fence.
■ Before turning on the saw, perform a dry run of the
cutting operation just to make sure that no problems
will occur when the cut is made.
■ Grasp the saw handle firmly, then squeeze the trigger
switch. Allow several seconds for blade to reach
maximum speed.
■ Use thumb to press the safety interlock toward the
handle.
■ Slowly lower the blade into and through the
workpiece.
■ Release the trigger switch and allow the saw blade to
stop rotate before raising the blade out of workpiece.
■ Slowly move the blade upward to the highest position
and release the safety lock.
