SAVE THESE INSTRUCTIONS.

Work area safety

1. Keep work area clean and well lit. Cluttered and

dark areas invite accidents.

2. 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.

3. Keep children and bystanders away while operat­ing a power tool. Distractions can cause you to lose

control.

Electrical safety

4. 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.

5. 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.

6. Do not expose power tools to rain or wet condi­tions. Water entering a power tool will increase the

risk of electric shock.

7. 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.

8. 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

9. 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.

10. Use safety equipment. Always wear eye protec­tion. Safety equipment such as dust mask, non-skid

safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.

11. Avoid accidental starting. Ensure the switch is in
the off-position before plugging in. Carrying power

tools with your finger on the switch or plugging in
power tools that have the switch on invites accidents.

12. 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.

13. Do not overreach. Keep proper footing and bal­ance at all times. This enables better control of the

power tool in unexpected situations.

14. 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.

15. 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

16. 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.

17. Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be con-

trolled with the switch is dangerous and must be
repaired.

18. 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 mea-

sures reduce the risk of starting the power tool acci­dentally.

19. 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.

20. 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.

21. Keep cutting tools sharp and clean. Properly main­tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.

22. 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.

Battery tool use and care

23. Ensure the switch is in the off position before
inserting battery pack. Inserting the battery pack into

power tools that have the switch on invites accidents.

24. 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.

25. Use power tools only with specifically designated
battery packs. Use of any other battery packs may

create a risk of injury and fire.

26. 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.

27. 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.

Service

28. 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.

29. Follow instruction for lubricating and changing
accessories.

30. Keep handles dry, clean and free from oil and
grease.

ADDITIONAL SAFETY RULES

1. Always use eye and ear protection. Other personal
protective equipment such as dust mask, gloves,
helmet and apron should be worn.

2. Keep guards in place.

3. Use only wheels with correct size and wheels hav­ing a maximum operating speed at least as high as
the highest No Load Speed marked on the tool’s
nameplate. When using depressed center wheels,
be sure to use only fiberglass-reinforced wheels.

ENB099-1

4. Check the wheel carefully for cracks or damage
before operation. Replace cracked or damaged
wheel immediately.

5. Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.

6. Do not use separate reducing bushings or adap­tors to adapt large hole abrasive wheels.

7. Use only flanges specified for this tool.

8. Do not damage the spindle, the flange (especially
the installing surface) or the lock nut. Damage to
these parts could result in wheel breakage.

9. For tools intended to be fitted with threaded hole
wheel, ensure that the thread in the wheel is long
enough to accept the spindle length.

10. Before using the tool on an actual workpiece, test
run the tool at the highest no load speed for at
least 30 seconds in a safe position. Stop immedi­ately if there is any vibration or wobbling that
could indicate poor installation or a poorly bal­anced wheel. Check the tool to determine the
cause.

11. Check that the workpiece is properly supported.

12. Hold the tool firmly.

13. Keep hands away from rotating parts.

14. Make sure the wheel is not contacting the work­piece before the switch is turned on.

15. Use the specified surface of the wheel to perform
the grinding.

16. Do not use cutting off wheel for side grinding.

17. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.

18. Pay attention that the wheel continues to rotate
after the tool is switched off.

19. Do not touch the workpiece immediately after
operation; it may be extremely hot and could burn
your skin.

20. Do not use the tool on any materials containing
asbestos.

FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and the bat-

tery cartridge is removed before adjusting or checking
function on the tool.

Installing or removing battery cartridge
(Fig. 1)

• Always switch off the tool before insertion or removal of

the battery cartridge.

• To remove the battery cartridge, withdraw it from the

tool while sliding the button on the front of the cartridge.

• To insert the battery cartridge, align the tongue on the

battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If you can see the red part on
the upper side of the button, it is not locked completely.
Insert it fully until the red part cannot be seen. If not, it
may accidentally fall out of the tool, causing injury to
you or someone around you.

• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.

Shaft lock (Fig. 2)

CAUTION:

• Never actuate the shaft lock when the spindle is mov­ing. The tool may be damaged.

Press the shaft lock to prevent spindle rotation when
installing or removing accessories.

Switch action (Fig. 3)

CAUTION:

• Before inserting the battery cartridge into the tool,
always check to see that the slide switch actuates
properly and returns to the “OFF” position when the
rear of the slide switch is depressed.

To start the tool, slide the slide switch toward the “I (ON)”
position. For continuous operation, press the front of the
slide switch to lock it.

To stop the tool, press the rear of the slide switch, then
slide it toward the “O (OFF)” position.

Indication lamp with multi function
(Fig. 4)

Indication lamps are located in two positions.
When the battery cartridge is inserted on the tool with the

slide switch positioned in the “O (OFF)” position, the indi­cation lamp flickers quickly for approximately one second.
If it does not flicker so, the battery cartridge or indication

lamp has broken.

- Overload protection

- When the tool is overloaded, the indication lamp lights
up. When the load on the tool is reduced, the lamp
goes out.

- If the tool continues to be overloaded and the indica­tion lamp continues to light up for approximately two
seconds, the tool stops. This prevents the motor and
its related parts from being damaged.

- In this case, to start the tool again, move the slide
switch to the “O (OFF)” position once and then to the “I
(ON)” position.

- Battery cartridge replacing signal

- When the remaining battery capacity gets small, the
indicator lamp lights up during operation earlier than
enough capacity battery use.

- Accidental re-start preventive function

- Even if the battery cartridge is inserted on the tool with
the slide switch in the “I (ON)” position, the tool does
not start. At this time, the lamp flickers slowly and this
shows that the accidental re-start preventive function
is at work.

- To start the tool, first slide the slide switch toward the
“O (OFF)” position and then slide it toward the “I (ON)”
position.

ASSEMBLY

CAUTION:

• Always be sure that the tool is switched off and the bat­tery cartridge is removed before carrying out any work
on the tool.

Installing side grip (handle) (Fig. 5)

CAUTION:

• Always be sure that the side grip is installed securely
before operation.

Screw the side grip securely on the position of the tool as
shown in the figure.

Installing or removing wheel guard
(Fig. 6)

CAUTION:

• When using a depressed center grinding wheel/Multi­disc, flex wheel, wire wheel brush, cut-off wheel or dia­mond wheel, the wheel guard must be fitted on the tool
so that the closed side of the guard always points
toward the operator.

Mount the wheel guard with the protrusion on the wheel
guard band aligned with the notch on the bearing box.
Then rotate the wheel guard around 180 degrees. Be sure
to tighten the screw securely.

To remove wheel guard, follow the installation procedure
in reverse.

Installing or removing depressed center
grinding wheel/Multi-disc

WARNING:

• Always use supplied guard when depressed center
grinding wheel/Multi-disc is on tool. Wheel can shatter
during use and guard helps to reduce chances of per­sonal injury.

Mount the inner flange onto the spindle. Fit the wheel/disc
on the inner flange and screw the lock nut onto the spin­dle. (Fig. 7)

To tighten the lock nut, press the shaft lock firmly so that
the spindle cannot revolve, then use the lock nut wrench
and securely tighten clockwise. (Fig. 8)

To remove the wheel, follow the installation procedure in
reverse.

Installing or removing diamond wheel
(optional accessory) (Fig. 9)

CAUTION:

• Make sure that the arrow on the tool should point in the
same direction as the arrow on the diamond wheel.

Mount the inner flange onto the spindle. Fit the diamond
wheel on over the inner flange and screw the lock nut onto
the spindle. Notice that flat side of the lock nut should face
the diamond wheel in case the diamond wheel is used.

WARNING:

• Only actuate the shaft lock when the spindle is not
moving.

OPERATION

WARNING:

• It should never be necessary to force the tool. The
weight of the tool applies adequate pressure. Forcing
and excessive pressure could cause dangerous wheel
breakage.

• ALWAYS replace wheel if tool is dropped while grind­ing.

• NEVER bang or hit grinding disc or wheel onto work.

• Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kickback.

• NEVER use tool with wood cutting blades and other
sawblades. Such blades when used on a grinder fre­quently kick and cause loss of control leading to per­sonal injury.

CAUTION:

• Make the depth of a single cut up to 5 mm. Adjust pres­sure on the tool so that the tool does not slow down
during the operation.

• After operation, always switch off the tool and wait until
the wheel has come to a complete stop before putting
the tool down.

• If the tool is operated continuously until the battery car­tridge has discharged, allow the tool to rest for 15 min­utes before proceeding with a fresh battery.

Grinding and sanding operation (Fig. 10)

ALWAYS hold the tool firmly with one hand on housing
and the other on the side handle. Turn the tool on and
then apply the wheel or disc to the workpiece.

In general, keep the edge of the wheel or disc at an angle
of about 15 degrees

to the workpiece surface.
During the break-in period with a new wheel, do not work

the grinder in the B direction or it will cut into the work­piece. Once the edge of the wheel has been rounded off
by use, the wheel may be worked in both A and B direc­tion.

Operation with diamond wheel (acces­sory)

WARNING:

• Forcing and exerting excessive pressure or allowing
the wheel to bend, pinch or twist in the cut can cause
overheating of the motor and dangerous kickback of
the tool.

CAUTION:

• After cutting operation, make sure that the diamond
wheel stops revolving completely. Then, place the tool.
It is dangerous to place the tool before turning off the
tool. If there are dust or dirt around the tool, the tool
may suck in them.

Be sure that the wheel does not contact the workpiece.
Turn the tool on and hold the tool firmly. Wait until the
wheel attains full speed. Now simply move the tool for­ward over the workpiece surface, keeping it flat and
advancing smoothly until the cutting is completed.

8

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and the bat­tery cartridge is removed before attempting to perform
inspection or maintenance.

The tool and its air vents have to be kept clean. Regularly
clean the tool's air vents or whenever the vents start to
become obstructed. (Fig. 11)

Replacing carbon brushes

Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes. (Fig. 12)

Insert the top end of slotted bit screwdriver into the notch
in the tool and remove the holder cap cover by lifting it up.

(Fig. 13)

Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps. (Fig. 14)

Reinstall the holder cap cover on the tool.
