Disconnect the plug from the power source

and/or the battery pack from the power tool

before making any adjustments, changing

accessories, or storing power tools. Such

preventive safety measures reduce the risk of

starting the power tool accidentally.

Store idle power tools out of the reach of

children and do not allow persons unfamiliar

with the power tool or these instructions to

operate the power tool. Power tools are

dangerous in the hands of untrained users.

Maintain power tools. Check for misalignment

or binding of moving parts, breakage of

parts and any other condition that may

affect the power tool’s operation. If damaged,

have the power tool repaired before use.

Many accidents are caused by poorly

maintained power tools.

Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting

edges are less likely to bind and are easier to

control.

Use the power tool, accessories and tool

bits etc. in accordance with these instructions,

taking into account the working conditions

and the work to be performed. Use of the

power tool for operations different from those

intended could result in a hazardous situation.

Service

Have your power tool serviced by a qualified

repair person using only identical

replacement parts. This will ensure that the

safety of the power tool is maintained.

Hold power tool by insulated gripping

surfaces, because the cutter may contact

its own cord. Cutting a ”live” wire may make

exposed metal parts of the power tool ”live”

and shock the operator.

Use clamps or another practical way to

secure and support the workpiece to a

stable platform. Holding the work by your

hand or against the body leaves it unstable

and may lead to loss of control.

Accessories must be rated for at least the

speed recommended on the tool warning

label. Wheels and other accessories running

over rated speed can fly apart and cause

injury.

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

the EZ TWIST

™ integrated 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 opera ting 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.

Wire and bristle brushes must never be

operated at speeds greater than
