5. Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral
gap greater than 10 mm or toothed saw blade.
Such blades create frequent kickback and loss of
control.
6. Do not "jam" the wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or binding
of the wheel in the cut and the possibility of kick-
back or wheel breakage.
When wheel is binding or when interrupting

a cut for any reason, switch off the power
tool and hold the power tool motionless until
the wheel comes to a complete stop. Never
attempt to remove the wheel from the cut while
the wheel is in motion otherwise kickback may
occur. Investigate and take corrective action to
eliminate the cause of wheel binding.
8. Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
Support panels or any oversized workpiece to

minimize the risk of wheel pinching and kick-
back. Large workpieces tend to sag under their
own weight. Supports must be placed under the
workpiece near the line of cut and near the edge
of the workpiece on both sides of the wheel.
10. Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, elec-
trical wiring or objects that can cause kickback.
11. Before using a segmented diamond wheel,
make sure that the diamond wheel has the
peripheral gap between segments of 10 mm or
less, only with a negative rake angle.
Additional Safety Warnings:
1. Never attempt to cut with the tool held upside
down in a vise. This can lead to serious acci-
dents, because it is extremely dangerous.
2. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material supplier
safety data.
3. Store wheels as per manufacturer recom-
mendations. Improper storage may damage the
wheels.

WARNING:
DO NOT let comfort or familiarity
with product (gained from repeated use) replace

rules stated in this instruction manual may cause
serious personal injury.
FUNCTIONAL
DESCRIPTION
CAUTION:
Always be sure that the tool is
switched off and unplugged before adjusting or
checking function on the tool.
Adjusting depth of cut
CAUTION:
After adjusting the depth of cut,
always tighten the lever securely.
Loosen the lever on the depth guide and move the base
up or down. At the desired depth of cut, secure the base
by tightening the lever.
For cleaner, safer cuts, set cut depth so that the dia-
mond wheel projects 2 mm or less below workpiece.
Using proper cut depth helps to reduce potential for
dangerous KICKBACKS which can cause personal
injury.

Align the edge of the front of the base with your cutting
line on the workpiece.

Switch action
CAUTION:
Before plugging in the tool, always
check to see that the switch trigger actuates
properly and returns to the "OFF" position when
