Safety instructions
Work area safety
keep work area clean and well lit. Cluttered or dark areas invite accidents.
do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety
Power tool plugs must match the outlet. never modify the plug in any way. do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
do not abuse the cord. never use the cord for carrying, pulling or unplugging the power tool. keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase the risk of electric shock.
when operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk
of electric shock.

Personal safety
stay alert, watch what you are doing and use common sense when operating a power tool. do not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
Use personal protective equipment. always wear eye protection. Protective equipment such as dust mask, nonskid safety shoes, hard hat, or
hearing protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or
carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may
result in personal injury.
do not overreach. keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
dress properly. do not wear loose clothing or jewellery. keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
if devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of these
devices can reduce dust-related hazards.
Power tool use and care
do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for
which it was designed.
do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and
must be repaired.
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
tools operation. if damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

a)
b)
c)
d)
e)
f)
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 and in the manner intended for the particular type of
power tool, 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.
This power tool is intended to function as a grinder, sander, wire brush, polisher, carving or cut-off tool. Read all safety warnings, instructions,
illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or
serious injury.
NOTE List only those operations that are applicable.
Operations such as grinding, sanding, wire brushing, polishing or cutting-off are not recommended to be performed with this power tool. Opera-
tions for which the power tool was not designed may create a hazard and cause personal injury.
NOTE List only those operations that were not included in the first warning. If all listed operations are applicable, then this warning is omitted,
but all subsequent warnings are given without exclusion.
Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be
attached to your power tool, it does not assure safe operation.
The rated speed of the grinding accessories must be at least equal to the maximum speed marked on the power tool. Grinding accessories
running faster than their rated speed can break and fly apart.
The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories
cannot be adequately controlled.
The arbour size of wheels, sanding drums or any other accessory must properly fit the spindle or collet of the power tool. Accessories that do

m)
n)
o)
not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
Mandrel mounted wheels, sanding drums, cutters or other accessories must be fully inserted into the collet or chuck. If the mandrel is insuffi-
ciently held and/or the overhang of the wheel is too long, the mounted wheel may become loose and be ejected at high velocity.
Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, sanding drum for
cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an
undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating acces-
sory and run the power tool at maximum no-load speed for one minute.
Damaged accessories will normally break apart during this test time.
Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust
mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be
capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated
by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments
of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.
Hold power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or
its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an
electric shock.
Always hold the tool firmly in your hand(s) during the start-up. The reaction torque of the motor, as it accelerates to full speed, can cause the
tool to twist.
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.
Clamping a small workpiece allows you to use your hand(s) to control the tool. Round material such as dowel rods, pipes or tubing have a
tendency to roll while being cut, and may cause the bit to bind or jump toward you.
Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into
the spinning accessory.
Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the
power tool out of your control.

Further safety instructions for all operations
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel, sanding band, brush or any other accessory. Pinching or snagging causes
rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s
rotation.
For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into
the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on
direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions
as given below.
a)
b)
After changing the bits or making any adjustments, make sure the collet nut, chuck or any other adjustment devices are securely tightened.
Loose adjustment devices can unexpectedly shift, causing loss of control, loose rotating components will be violently thrown.
Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the
accessory into your body.
Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal
may cause electrical hazards.
Do not operate the power tool near flammable materials. Sparks could ignite these materials.
Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.
Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. The operator can control kickback
forces, if proper precautions are taken.
Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have
a tendency to snag the rotating accessory and cause loss of control or kickback.

Additional safety instructions for grinding and cutting-off operations
Safety warnings specific for grinding and abrasive cutting-off operations:
a)
b)
c)
d)
e)
f)
g)
Do not attach a toothed saw blade. Such blades create frequent kickback and loss of control.
Always feed the bit into the material in the same direction as the cutting edge is exiting from the material (which is the same direction as the
chips are thrown). Feeding the tool in the wrong direction causes the cutting edge of the bit to climb out of the work and pull the tool in the
direction of this feed.
When using rotary files, cut-off wheels, high-speed cutters or tungsten carbide cutters, always have the work securely clamped. These wheels
will grab if they become slightly canted in the groove, and can kickback. When a cut-off wheel grabs, the wheel itself usually breaks. When a
rotary file, high-speed cutter or tungsten carbide cutter grabs, it may jump from the groove and you could lose control of the tool.
Use only wheel types that are recommended for your power tool and only for recommended applications. For example: do not grind with the
side of a cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to
shatter.
For threaded abrasive cones and plugs use only undamaged wheel mandrels with an unrelieved shoulder flange that are of correct size and
length. Proper mandrels will reduce the possibility of breakage.
Do not “jam” a cut-off 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 snagging of the wheel in the cut and the possibility of kickback or wheel breakage.
Do not position your hand in line with and behind the rotating wheel. When the wheel, at the point of operation, is moving away from your hand,
the possible kickback may propel the spinning wheel and the power tool directly at you.
When wheel is pinched, snagged 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 cut-off 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 pinching or snagging.
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 kickback. 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.

Service
a)
Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to
the brush. The wire bristles can easily penetrate light clothing and/or skin.
Allow brushes to run at operating speed for at least one minute before using them. 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.
Direct the discharge of the spinning wire brush away from you. Small particles and tiny wire fragments may be discharged at high velocity during
the use of these brushes and may become imbedded in your skin.
Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire
when used with another battery pack.
Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects,
that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
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.

Operating Instructions
Using the Rotary Tool
The first step in learning to use the Rotary Tool is to get the “feel” of it. Hold it in your hand and feel its weight and balance. Feel the taper of the
housing. Always hold the tool away from your face. Accessories can be damaged during handling, and can fly apart as they come up to speed.
This is not common, but it does happen. Whenever you hold the tool, be careful not to cover the air vents with your hand. This blocks the air flow
and causes the motor to overheat. For best control in close work, grip the Rotary Tool like a pencil between your thumb and forefinger (Figure 2).
The “Golf Grip” method of holding the tool can be used for more aggressive operations such as grinding a flat surface or using cut off wheels
(Figure3).
Practice on scrap materials first to see how the Rotary Tool's high speed action performs. Keep in mind that the work is done by the speed of the
tool and by the accessory in the collet. You should not lean on or push the tool during use. Instead, lower the spinning accessory lightly to the work
and allow it to touch the point at which you want cutting (or sanding or etching, etc.) to begin. Con centrate on
guiding the tool over the work using very little pressure from your hand. Allow the accessory to do the work. Usually, it is best to make a series of
passes with the tool rather than attempt to do all the work in one pass. To make a cut, for example, pass the tool back and forth over the work,
much as you would a small paint brush. Cut a little material on each pass until you reach the desired depth. For most work, the gentle touch is
best. With it, you have the best control, are less likely to make errors, and will get the most efficient work out of the accessory.

To select the right speed for each job, use practice piece of material.
SLIDE "ON/OFF" SWITCH
The tool is switched "ON" by the slide switch located on the topside of the motor housing.
TO TURN THE TOOL "ON", slide the switch button forward. The tool will start working
at a speed of 15,000 rpm
TO TURN THE TOOL "OFF", slide the switch button backward. If for some reasons the
on/off switch doesn't work there is always the option to alternatively turn off the tool by the following methods:
Press decrease speed control button(G2) to bring the speed of the tool to the lowest speed level (5,000 RPM).
Hold decrease speed control button(G2) for 5 seconds. Then the tool will be turned off.
SPEED CONTROL BUTTONS
The tool is equipped with speed control buttons. The speed may be adjusted during operation by pressing on increase or decrease buttons located
on the topside of the battery housing. Speed will increment or decrement from a minimum of 5,000 to a maximum of 25,000 rpm. The LED lights
will illuminate according to the chosen speed. Every time the tool is turned off the speed set goes back to the medium level (15,000 rpm) so it might
be necessary to increase/decrease the speed to the level that it was being used(Figure 4).
The speed of Rotary Tool is controlled by setting the blue speed control buttons.

Needs for Slower Speeds
Certain materials, however, (some plastics and precious metals, for ex ample) require a relatively slow speed because at high speed the friction
of the accessory generates heat and may cause damage to the material.
Slow speeds (15,000 RPM or less) usually are best for polishing operations employing the felt polishing accessories. They may also be best for
working on deli cate projects as delicate wood carving and fragile model parts. All brushing applications require lower speeds to avoid wire
discharge from the holder.
Higher speeds are better for carving, cutting, shaping, cutting dadoes or rabbets in wood.
Hardwoods, metals and glass require high speed operation, and drilling should also be done at high speeds.
Many applications and accessories in our line will provide the best performance at full speed, but for certain materials, applications, and accesso-
ries, you need slower speeds, which is the reason our variable speed models are available.
To aid you in determining the optimum operational speed for different materials and different accessories, we have construct ed a series of tables.
By referring to these tables, you can discover the recommended speeds for each type of accessory. Look these tables over and become familiar
with them.
Ultimately, the best way to determine the correct speed for work on any material is to practice for a few minutes on a piece of scrap, even after
referring to the chart. You can quickly learn that a slower or faster speed is more effective just by observing what hap pens as you make a pass or
two at different speeds. When working with plastic, for example, start at a slow rate of speed and increase the speed until you observe that the
plastic is melting at the point of contact. Then reduce the speed slight ly to get the optimum working speed.
Some rules of thumb in regard to speed:
1.
2.
3.
4.
5.
Plastic and other materials that melt at low temperatures should be cut at low speeds.
Polishing, buffing and cleaning with any type of bristle brush must be done at speeds not greater than 15,000 RPM to prevent damage to the
brush.
Wood should be cut at high speed.
Iron or steel should be cut at high speed. If a high-speed steel cutter starts to chatter — this normally means it is running too slow.
Aluminum, copper alloys, lead alloys, zinc alloys and tin may be cut at various speeds, depending on the type of cutting being done. Use paraffin
or other suitable lubricant on the cutter to prevent the cut material from adhering to the cutter teeth.
- 14 -

STALL PROTECTION
This tool has a stall protection feature built into it to protect the motor and battery in the event of a stall. If you stall the tool for too long, or bind the
bit in a work piece, especially at high speeds, it will automatically turn itself off. Simply take the tool out of the material you were stalled in, turn it
off for 3 seconds, then turn it back on again to continue using it. When the battery becomes close to empty, the tool may shut down automatically
more frequent than normal. If this happens, it is time to recharge the battery.
Changing Collets
Using collets is the most precise way to hold an accessory in a high speed rotary tool. Even at high speeds and maximum pressure, collets stay
tight(Figure 5,Figure 6).

Balancing Accessories
For precision work, it is important that all accessories be properly balanced. To balance an accessory, slightly loosen the collet nut and give the
accessory or collet a 1/4 in. turn. Retighten collet nut and run the rotary tool. You should be able to tell by the sound and feel if the accessory is
running in balance. Continue adjusting in this fashion until the best balance is achieved. Replace accessories if they become damaged or
unbalanced.
Shield Rotary Tool Attachment
The rotary shield attachment provides a clear and simple solution for redirecting debris and sparks away from the user without interfering with the
task at hand. The tool shield can be used with right- or left-hand grip positions and works to deflect debris on a variety of applications, including
cutting, sanding, grinding and polishing. The shield can be quickly adjusted into position, provides easy access to the accessory without interfering
with the workpiece.
Installation Instructions:
Step 1. Remove the housing cap A from the end of the tool and set housing cap aside. The original housing cap must be reinstalled when this
attachment is not used (Fig.10).
Step 2. Screw the Shield onto the tool using the lock nut B (Fig.11).
