tion your body and arm in a way that
allows you to resist KICKBACK forces.
KICKBACK forces can be controlled by the
operator, if proper precautions are taken.
When wheel is binding, or when interrupt-
ing a cut for any reason, release the trig-
ger and hold the tool motionless in the
material until the wheel comes to a com-
plete stop. Never attempt to remove the
tool from the work or pull the tool back-
ward while the wheel is in motion or KICK-
BACK may occur. Investigate and take
corrective actions to eliminate the cause of
wheel binding.
When restarting a tool in the workpiece,
center the wheel in the kerf and check that
teeth are not engaged into the material. If
wheel is binding, it may walk up or KICK-
BACK from the workpiece as the tool is
restarted.
Support large panels to minimize the risk
of wheel pinching and KICKBACK. Large
panels tend to sag under their own weight.
Supports must be placed under the panel on
both sides, near the line of cut and near the
edge of the panel.
To minimize the risk of wheel pinching and
kickback. When cutting operation requires
the resting of the tool on the workpiece, the
tool shall be rested on the larger portion and
the smaller piece cut off.
Do not use dull or damaged wheel.
Unsharpened or improperly set wheels pro-
duce narrow kerf causing excessive friction,
wheel binding and KICKBACK.
Wheel depth and bevel adjusting locking
levers must be tight and secure before
making cut. If wheel adjustment shifts while
cutting, it will cause binding and KICKBACK.
Use extra caution when making a “Pocket
Cut” into existing walls or other blind
areas. The protruding wheel may cut objects
that can cause KICKBACK.
11. Use only diamond wheels. NEVER use
tool with wood cutting blades or other
sawblades. Such blades when used on
this tool frequently kick and cause loss of
control leading to personal injury.
12. Check the wheel carefully for cracks or
damage before operation. Replace
cracked or damaged wheel immediately.
13. Use only flanges specified for this tool.
14. Be careful not to damage the spindle,
flanges (especially the installing surface)
or bolt. Damage to these parts could
result in wheel breakage.
15. Hold the tool firmly.
16. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
17. Wait until the wheel attains full speed
before cutting.
18. Stop operation immediately if you notice
anything abnormal.
19. Never attempt to cut with the tool held
upside down in a vise. This can lead to
serious accidents, because it is extremely
dangerous.
20. Do not stop the wheel by lateral pressure
on the disc.
21. Some material contains chemicals which
may be toxic. Take caution to prevent dust
inhalation and skin contact. Follow mate-
rial supplier safety data.
