If cutting into existing walls or other blind areas where electrical wiring may exist is unavoidable,
disconnect all fuses or circuit breakers feeding this worksite.
Do not operate the flexible shaft with a sharp bend. Over bending the shaft can generate
excessive heat on the jacket or hand piece. The recommended minimum is 5" radius.
Always disconnect the power cord from the power source before making any adjustments
or attaching any accessories. You may unexpectedly cause the tool to start leading to serious
personal injury.
Be aware of the switch location, when placing the tool down or when picking the tool up.
You may accidentally activate the switch.
Always hold the hand piece firmly in your hands during the start-up. The reaction torque of
the motor, as it accelerates to full speed, can cause the shaft to twist.
Always wear safety goggles and dust mask. Use only in well ventilated area.
Using personal safety devices and working in safe environment reduces risk of injury.
After changing the bits or making any adjustments, make sure the collet nut and
wrench/nose cap are both securely tightened. Loose adjustment devices can unexpectedly shift,
causing loss of control, loose rotating components will be violently thrown.
Do not reach in the area of the spinning bit. The proximity of the spinning bit to your hand
may not always be obvious.
Allow brushes to run at operating speed for at least one minute before using wheel.
During this time no one is to stand in front or in line with the brush. Loose bristles or wires
will be discharged during the run-in time.
Carefully handle both the tool and individual grinding wheels to avoid chipping or
cracking. Install a new wheel if tool is dropped while grinding. Do not use a wheel that may
be damaged. Fragments from a wheel that bursts during operation will fly away at great velocity
possibly striking you or bystanders.
Never use dull or damaged bits. Sharp bits must be handled with care. Damaged bits can
snap during use. Dull bits require more force to push the tool, possibly causing the bit to break.
Use clamps to support workpiece whenever practical. Never hold a small workpiece in one
hand and the tool in the other hand while in use. Allow for sufficient space, at least 6",
between your hand and the spinning bit. Round material such as dowel rods, pipes or tubing
have a tendency to roll while being cut, and may cause the bit to “bite” or jump toward you.
Clamping a small workpiece allows you to use both hands to control the tool.
Inspect your workpiece before cutting. When cutting irregularly shaped workpieces, plan
your work so it will not slip and pinch the bit and be torn from your hand. For example, if
carving wood, make sure there are no nails or foreign objects in the workpiece. Nails or foreign
objects can cause the bit to jump.
Never start the tool when the bit is engaged in the material. The bit cutting edge may grab the
material causing loss of control of the cutter.
Avoid bouncing the wheel, especially when working corners, sharp edges etc. This can cause
loss of control and kick-back.
