KEEP ALL SAFETY WARNINGS AND
INSTRUCTIONS FOR THE FUTURE !

Safety warnings common for grinding,
sanding,wirebrushing, polishing, carv­ingor abrasive cutting-offoperations:

a) This power tool is intended to function

as a grinder, sander, wire brush, polish­er, carvingorcut-offtool.Read all safe­ty warnings, instructions, illustrations
and specificationsprovidedwith this
power tool. Failure to follow all instruc-

tions listed below mayresultinelectric
shock, fire and/orserious injury.

c) Do notuseaccessorieswhich are not

specificallydesignedandrecommend­ed by thetoolmanufacturer. Just be-

cause the accessory canbeattached to
your power tool, it does not assure safe
operation.

d) The rated speedofthegrinding acces-

soriesmustbeatleast equal to the
maximum speedmarkedonthepower
tool. Grinding accessories running faster

than theirrated speedcanbreak and fly
apart.

e) The outsidediameter andthethickness

of your accessory must be within the
capacity ratingofyour power tool. In-

correctly sized accessoriescannotbead­equately controlled.

f) The arbour size of wheels, sanding

drums or any other accessorymust
properly fit thespindle or colletofthe
power tool. Accessories thatdonot

match the mounting hardware of the
power toolwillrunoutofbalance, vibrate
excessively and may cause loss of control.

g) Mandrel mountedwheels, sanding

drums, cuttersorother accessories
must be fully inserted into the collet or
chuck. If the mandrel is insufficiently held

and/or the overhangofthewheelistoo
long, the mountedwheel may become
loose andbeejected at highvelocity.

h) Do not useadamaged accessory. Be-

fore each use inspecttheaccessory
such as abrasive wheels for chips and

GB

cracks, sanding drum for cracks, tear
or excess wear, wirebrushforlooseor
c

racked wires.Ifpower tooloracces­sory is dropped, inspect for damage or
install an undamaged accessory. After
inspecting andinstalling an accessory,
position yourself andbystanders away
from the plane of the rotating accesso­ry and runthe power tool at maximum
no-load speed for one minute. Damaged

accessorieswill normallybreak apart dur­ing this test time.

i) Wear personal protective equipment.

Depending on application, use face
shield, safety goggles or safety glass­es. As appropriate, weardust mask,
hearing protectors, gloves and work­shop apron capable of stoppingsmall
abrasive or workpiecefragments. The

eyeprotection 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 exposureto
high intensity noise may cause hearing
loss.

j) Keepbystandersasafe distance away

from work area.Anyone enteringthe
work areamustwearpersonal protec­tive equipment. Fragments of workpiece

or of a broken accessory may fly away and
cause injury beyond immediate areaofop­eration.

k) Hold power toolbyinsulated gripping

surfaces only,whenperforming an op­eration where the cutting accessory
may contacthiddenwiring or its own
cord. Cutting accessorycontactinga“live”

wire may makeexposed metal parts of the
power tool “live” and could give the opera­toranelectric shock.

l) Always holdthetool firmlyinyour

hand(s)duringthestart-up. The reac­tion torque of the motor, as it accelerates
to fullspeed,cancause the tooltotwist.

m) Use clamps to supportworkpiece

whenever practical. Never holdasmall
workpiece in one hand andthetoolin
the other handwhileinuse. Clampinga

small workpiece allowsyoutouseyour

hand(s)tocontrol the tool.Round mate­rialsuchasdowel rods, pipesortubing

ave a tendencytorollwhile beingcut,
and maycause the bittobindor jump to­ward you.

n) Position the cord clearofthespinning

accessory. If you lose control, thecord
maybe cutorsnagged andyour handor
arm maybepulled into thespinning ac­cessory.

o) Never laythepower tooldownuntil the

accessory has come to a complete
stop. The spinning accessory may grab

thesurface and pull the power tool outof
your control.

p) Afterchanging the bits or makingany

adjustments, makesurethecollet nut,
chuck or any other adjustmentdevices
are securely tightened. Loose adjust-

ment devices can unexpectedly shift,
causing lossofcontrol, looserotating com­ponents willbeviolently thrown.

q) Do not runthepower toolwhile carry-

ingitatyourside. Accidentalcontact
with the spinning accessorycould snag
yourclothing, pulling the accessory into
your body.

r) Regularly cleanthepower tool’s air

vents. The motor’s fanwilldrawthe dust
inside the housing and excessive accumu­lationofpowdered metal maycause elec­trical hazards.

s) Do notoperate the power tool near

flammable materials. Sparks could ignite
these materials.

t) Do notuseaccessories that require liq-

uid coolants. Using water or other liquid
coolants may resultinelectrocutionor
shock.

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. Pinchingorsnagging
causesrapid stallingofthe rotating accesso-

- 12 -

ry which in turn causes the uncontrolled
power tooltobeforced in the direction oppo­s

iteofthe accessory’s rotation.

Forexample,ifanabrasive wheelissnagged
or pinchedbythe workpiece, the edgeofthe
wheel thatisentering into the pinch point can
dig into thesurface of thematerial causing
the wheeltoclimb outorkickout.Thewheel
may eitherjumptoward or away from the op­erator, dependingondirectionofthe wheel’s
movementatthe pointofpinching. Abrasive
wheels may also break under thesecondi­tions.

Kickback is theresult of power tool misuse
and/or incorrect operating procedures or con­ditions and canbeavoidedbytakingproper
precautionsasgiven below.

a) Maintainafirmgriponthepowertool

andposition your body and armto
allowyou to resist kickbackforces. The

operator can control kickback forces, if
proper precautions are taken.

b) Use special carewhen working cor-

ners, sharp edges etc. Avoid bouncing
and snaggingtheaccessory. Corners,

sharp edgesorbouncing have a tendency
to snag the rotating accessory andcause
lossofcontrol or kickback.

c) Do not attachatoothed saw blade.

Such bladescreate frequentkickback and
loss of control.

d) Alwaysfeedthebit into thematerialin

the same directionasthecuttingedge
is exiting from the material(which is
the same direction as the chips are
thrown). Feeding the toolinthe wrong di-

rectioncauses the cutting edgeofthe bit
to climb outof thework and pull the toolin
the directionofthis feed.

e) When using rotary files, cut-offwheels,

high-speed cutters or tungsten carbide
cutters, alwayshave the work securely
clamped. These wheels will grab if they

becomeslightlycantedinthe groove, and
can kickback. Whenacut-off wheelgrabs,
the wheel itself usually breaks. Whenaro-

tary file, high-speed cutter or tungsten car­bide cutter grabs, it may jump from the
g

roove and you could lose control of the
tool.

Safety warnings specific for grinding and
abrasive cutting-off operations:

a) Useonlywheeltypesthatare recom-

mended for your power tool andonly
for recommended applications.Forex­ample: do not grind with the side of a
cut-off wheel. Abrasive cut-off wheelsare

intended for peripheral grinding, side
forces applied to these wheels maycause
themtoshatter.

b) Forthreaded abrasive cones andplugs

use only undamaged wheel mandrels
withan unrelieved shoulder flangethat
areofcorrect size and length. Proper

mandrels will reduce the possibilityof
breakage.

c) Do not“jam”acut-offwheelorapply

excessive pressure. Do not attemptto
make an excessive depthofcut.Over-

stressing thewheel increases the loading
andsusceptibility to twisting or snagging
of thewheel in the cut and the possibility of
kickback or wheel breakage.

d) Do not position your handin linewith

and behind the rotating wheel. When
the wheel,atthe pointofoperation,is
movingawayfromyour hand, the possi­blekickback may propel thespinning
wheel and the power tool directlyatyou.

e) Whenwheelispinched,snagged or

when interruptingacutforanyreason,
switch offthepower tool and holdthe
power toolmotionless until the wheel
comes to a complete stop. Never at­temptto removethecut-offwheelfrom
the cutwhilethe wheelisin motion
otherwise kickback may occur. Investi-

gate and take corrective actiontoelimi­nate thecauseofwheel pinchingorsnag­ging.

f) Do not restartthecuttingoperation in

the workpiece. Letthewheel reachfull
speed and carefully re-enter the cut.

The wheel may bind,walkuporkickback
if the power tool isrestartedinthe work­p

iece.

g) Support panelsoranyoversizedwork-

piecetominimize the riskofwheel
pinching and kickback. Large work-

pieces tend to sag under theirown weight.
Supports must be placed under the work­piece near the lineofcutand near the
edgeofthe workpiece on bothsidesofthe
wheel.

h) Use extra caution when makinga

“pocket cut” into existingwallsor
otherblind areas. The protrudingwheel

maycutgasorwater pipes, electrical
wiringorobjects that cancause kickback.

Safety warnings specific for wire brushing
operations:

a) Be awarethatwire bristles arethrown

by the brush even during ordinaryop­eration. Do not overstress the wiresby
applying excessive load to the brush.

Thewire bristlescaneasily penetrate light
clothing and/orskin.

b) Allow brushestorunatoperating

Description of the machine

Because of its construction, the LWB/E angle
drill can be operated even at inaccessible
areas that cannot be reached with conven­tional drills. This is made possible through the
long slender neck of the aluminium die-cast
head and the mitre gear, which enables the
drill to be aligned by 90°. With the compre­hensive range of commercially available ac­cessories, other work is also possible such as
drilling, grinding, milling and polishing and
more. The LWB/E is powered by a quiet direct
current motor for a long service life and great­est reliability. The supplied collets can clamp
the shafts of the bits and cutters up to max.

3.2 mm, guaranteeing greatest concentric ac­curacy.

Operation

Clamping and replacing insert units

Attention:

• Never work without safety glasses.

• Wear a protective mask if large amounts of
dust or harmful dusts accumulate.

• Never press the lock button while the device
is operating.

• Depending on the collet size, bits and cut­ters may have a shaft diameter of max. 3.2
mm.

• Insert the tools are far as possible when
clamping. Ensure that the shaft of the tool
does not stand out more than 30 mm from
the collet. Excessively protruding shafts can
bend easily and contribute to poor concen­tricity.

• Do not in any case use bits and cutters with
an arbour length of more than 55 mm!

• When using collets, always make sure that
the collet chuck and the utilised tool have
the same shaft diameter! The arbour of the
tool must be seated firmly and securely in
the collet!

• Do not work with damaged, bent or worn
bits and cutters! Make sure the tools are in
perfect condition. Damaged or worn tools
can break and cause injuries!

• When storing the bits and cutters, make
sure they are reliably protected from dam­age!

• A correct and consistent speed achieves a
high grinding performance, not excessive

contact pressure!

• By tendency: Bits and cutters with smaller
d

iameters require higher speeds than those

with a larger diameter.

• Attention: You absolutely must observe the
permissible maximum speed of the bits and
cutters! The tool can break when the maxi­mum permissible speed is exceeded. Flying
parts can cause damage and severe 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.

1. Rotate union nut 2 (Fig. 2) slightly to the left

or right while simultaneously pressing lock­ing button 1 until it engages.

2. Unscrew union nut.

3. Insert desired collet chuck 3 with corre-

sponding insert unit 4 and re-tighten union
nut.

Working with the drill

1. Activate the device with switch 4 (Fig. 1)

and set the right speed for the work on knob
1 (Fig. 1).

2. Hold the device while working as shown in

Fig. 4. Make sure not to cover the ventila­tion slots! If it overheats you absolutely
must switch off the machine and allow it to
cool down.

3.

Hold drill as shown in Fig. 4 so as not to ob­struct the ventilation slits 1.

Note:

If the drill overheats, switch it off immediately
and allow it to cool.

Maintenance, cleaning and care

Attention:

Disconnect the mains plug prior to every ad­justment, maintenance measure or repair!

- 16 -

Note:

Every device is dirtied by dust when working.
Cleaning is therefore essential. To ensure a
long service life, however, the machine should
be cleaned with a soft cloth or brush after
each use.
Mild soap or other suitable cleaning agent
may be used in this context. Solvents or
cleaning agents containing alcohol (e.g.
petrol, cleaning alcohols, etc.) should be
avoided, since these can attack plastic cas­ings.

The apertures required for cooling the motor
must always be kept free of dust and dirt.
