Adjusting The Cutting Angle - RIDGID R4141 Manual Del Operador

OPERATION
WARNING:
To avoid serious personal injury, always tighten
vise adjustment bolt securely before making a cut.
Failure to do so could result in movement of the
material while making a cut.
 Place the material flat on the machine base with one
surface securely against the adjustable fence.
 Align cutting line on the material with the edge of the
abrasive wheel.
 Push in the vise crank handle to set the vise clamp against
the material. Turn the vise crank handle 1/2 to 1 turn clock-
wise to securely clamp the material to the fence.
 Firmly secure the material to be cut using the machine's
vise (adjustable fence and vise clamp) and, when pos-
sible, a C-clamp.
 When cutting long pieces, support the opposite end of
the material with a roller stand or with a work surface
level with the machine base.
WARNING:
Never perform any cutting operation freehand (with-
out placing material in the vise). Material will get hot
during cutting operation. Keep hands off of metal
being cut to avoid serious personal injury.
 Before turning on machine, perform a dry run of the
cutting operation just to make sure that no problems will
occur when the cut is made.
 Start the machine by grasping the handle and fully
squeezing the on/off switch. Allow several seconds for
the wheel to build up to full speed before letting it come
into contact with the material to be cut.
 Once it reaches full speed slowly lower the "D" handle
until the cut-off wheel comes in contact with the material
being cut. Continue to use steady and even pressure to
obtain a uniform cut through the material. Never force the
wheel into the material being cut.
 When the cut is complete, release the on/off switch and
allow the wheel to stop rotating before raising the wheel
out of material.
WARNING:
Do not touch the cut material until it cools or you
can be burned. Failure to heed this warning could
result in serious personal injury.
USING THE ADJUSTABLE FENCE
See Figure 9, page 20.
The adjustable fence is located at the rear of the cut-off
machine. As mentioned previously, it is used along with the
vise clamp to provide a clamp for holding the workpiece
securely when making cuts. It also makes the cut-off
machine more versatile.
The fence can be rotated to obtain cutting angles from 0°
to 45°. It also can be moved back to allow greater cutting
widths in thin stock, or forward to allow greater cutting
depths in tall or thick stock.

ADJUSTING THE CUTTING ANGLE

See Figures 10 - 11, page 20.
 Unplug the cut-off machine.
 Loosen the miter lock handle by pushing down and rotat-
ing counterclockwise.
 Rotate fence until the desired angle of cut on the scale
is aligned with the indicator in machine base.
 Tighten the miter lock handle. This will secure the fence in
place at desired angle. For precise cuts, check the angle
of cut for the fence against the wheel with a protractor,
bevel square, or other similar device.
ADJUSTING THE WIDTH OF CUT
See Figure 11, page 20.
The stationary vise can be repositioned by removing the
vise adjustment bolt.
 Unplug the cut-off machine.
 To increase the width of cut of the cut-off machine, use
the arbor wrench to loosen and remove the vise adjust-
ment bolt securing the stationary vise to machine base.
 Reposition the stationary vise with one of three threaded
holes in back of the machine base.
 Install vise adjustment bolt into machine base.
 Check and adjust fence to desired cutting angle.
 Tighten the vise adjustment bolt. The maximum width
capacity is approximately 8-1/4 in. at 90° and 5 in. at
45°.
 Return arbor wrench to its storage area in base.
USING THE qUICK LOCK-RELEASE LEVER
AND VISE CLAMP
See Figures 12 - 13, page 21.
The quick lock-release lever engages the vise clamp to be
used along with the fence to provide a vise for securing the
workpiece to be cut. It also allows you to open and close
the vise quickly without repetitive turning of the vise crank
handle.
To loosen:
 Unplug the cut-off machine.
 Release tension on the vise clamp by rotating the vise
crank handle 1/2 to 1 turn counterclockwise.
