DEPTH STOP
The depth stop limits the wheel's downward travel, It
allows the wheel to go below the machine base
enough to maintain full cutting capacities.
The adjustable depth stop is a nylo¢=bolt threaded into
the base of the machine at the rear. To adjust the
depth stop use an 8 mm wrench to raise or lower the
depth step bolt.
The depth step is factory set to provide maximum
cuffing capacity for the 14 in, (356 ram) abrasive
whee( provided with your cut-off machine.
When the diameter of the wheel has been reduced
due to wear, it may be necessary to adjust the depth
stop to provide ma;,_imum cutting capacity. When a
new a_rasive wheel is installed, it is necessary to
check the clearance of the wheel to the machine base
Support,

CUT-OFF
See Figures 14 and 15.
Acut-off is made by cutting across the width of the
workpiece. A straight crosscut is made with the
adjustable flip fence set at the zero degree position.
Ang]ed cut-offs are made with the adjustable flip
fence assembly set at some angle other than zero.
To cut with your cut-off machine:
• Firmly secure the matedal to be cut using the
machine's vise (adjustable flip fence assembly,
extension fence, and vise clamp).
•Using the fence lock handle, loosen the adjustable
flip fence assembly. See Figures 14 and 15.
II Rotate the adjustable flip fence assembly to the
angle needed,
• Retighten fence lock handle,
_1, WARNING: To avoid seriouspersonalinjury,
always tighten fence lock handle securelybefore
makinga cut. Failureto do so could resultin
movement ofthe workpiecowhilemaking a cut.
•Place the workpiece flat on the machine base with
one surface securely against the adjustable flip
fence.
III Aligncuttingline on the workpiecewiththe edge of
the abrasive wheel.
•Push in the vise crank handle to set the vise clamp
against the workplace. Turn the vise crank handle
1/2 to 1 turn clockwise to securely clamp the
workplace to the fence.
_1, WARNING: To avoid serious personal injury,
keep your hands at least 3 in. (76.2 mm) from
wheel.
II When cutting long pieces, support the opposite
end of the materiel with e roller stand or with a
work surface level with the machine base.
,_, WARNING: Never perform any cutting
operationfreehand (without placing workpieoe in
