KEEP ALL SAFETY WARNINGS AND

INSTRUCTIONS FOR THE FUTURE !

Safety warnings common for grinding,

sanding,wirebrushing, polishing, carv-

ingor abrasive cutting-offoperations:

a) This power tool is intended to function

as a grinder, sander, wire brush, polish-

er, carvingorcut-offtool.Read all safe-

ty 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

specificallydesignedandrecommend-

ed 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 accessoriescannotbead-

equately 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

cracks, sanding drum for cracks, tear

or excess wear, wirebrushforlooseor

racked wires.Ifpower tooloracces-

sory 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 accesso-

ry and runthe power tool at maximum

no-load speed for one minute. Damaged

accessorieswill normallybreak apart dur-

ing this test time.

i) Wear personal protective equipment.

Depending on application, use face

shield, safety goggles or safety glass-

es. As appropriate, weardust mask,

hearing protectors, gloves and work-

shop apron capable of stoppingsmall

abrasive or workpiecefragments. The

eyeprotection must be capable of stop-

ping flying debris generated by various op-

erations. 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 protec-

tive equipment. Fragments of workpiece

or of a broken accessory may fly away and

cause injury beyond immediate areaofop-

eration.

k) Hold power toolbyinsulated gripping

surfaces only,whenperforming an op-

eration 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 opera-

toranelectric shock.

l) Always holdthetool firmlyinyour

hand(s)duringthestart-up. The reac-

tion 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 mate-

rialsuchasdowel rods, pipesortubing

and maycause the bittobindor jump to-

ward you.

n) Position the cord clearofthespinning

accessory. If you lose control, thecord

maybe cutorsnagged andyour handor

arm maybepulled into thespinning ac-

cessory.

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,

ment devices can unexpectedly shift,

causing lossofcontrol, looserotating com-

ponents 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 accumu-

lationofpowdered metal maycause elec-

trical 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.

tions

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 oppo-

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 op-

erator, dependingondirectionofthe wheel’s

movementatthe pointofpinching. Abrasive

wheels may also break under thesecondi-

tions.

Kickback is theresult of power tool misuse

and/or incorrect operating procedures or con-

ditions 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 car-

bide cutter grabs, it may jump from the

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.Forex-

ample: 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 possi-

blekickback 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 at-

temptto removethecut-offwheelfrom

the cutwhilethe wheelisin motion

otherwise kickback may occur. Investi-

gate and take corrective actiontoelimi-

nate thecauseofwheel pinchingorsnag-

ging.

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 work-

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 work-

piece 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 ordinaryop-

eration. 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 conven-

tional 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 compre-

hensive range of commercially available ac-

cessories, 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 great-

est reliability. The supplied collets can clamp

the shafts of the bits and cutters up to max.

3.2 mm, guaranteeing greatest concentric ac-

curacy.

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 cut-

ters 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 concen-

tricity.

• 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 dam-

age!

• A correct and consistent speed achieves a

high grinding performance, not excessive

contact pressure!

• By tendency: Bits and cutters with smaller

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 maxi-

mum permissible speed is exceeded. Flying

parts can cause damage and severe in-

juries!

• Prevent unintentional starting. Ensure the

switch is in the off-position before connect-

ing 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 lock-

ing 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 ventila-

tion slots! If it overheats you absolutely

must switch off the machine and allow it to

cool down.

Hold drill as shown in Fig. 4 so as not to ob-

struct 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 ad-

justment, 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 cas-

ings.

The apertures required for cooling the motor

must always be kept free of dust and dirt.
