mation on how to correctly use the product.

Short description of functions

The SB2is a medical device for the treatment of callus and nails. The handpiece is

compatible with rotating tools such as diamond polishers, steel cutters and ceramic

cutters. These can reach at speeds up to 22,000 rpm and therefore provide an efficient

way of removing tissue. The direction of rotation can be changed by pressing a button.

The integrated filtered suction function effectively sucks up any dust particles. The

rotation speed and suction function can be adjusted using the keyboard. The device

display will notify you when the filter needs to be changed and when the device is due

for inspection.

Safety Instructions

The equipment should only be used by trained

operators.

The installation of the working area has to cor-

respond to the relevant regulations. Set up the

unit in such a way, that the air slits are not

blocked and the extracted air can escape well.

To avoid the risk of electrocution only connect

the device to the mains power supply.

If you pull the power plug, it will stop the con-

nection to the mains power supply. Set up the

unit so that the power plug is always accessi-

ble. The power switch should also always be

easily accessible.

Only switch on the unit if the handpiece rests

secured in the handpiece holder, or if you hold

it safely in your hand.

Prevent any liquids from entering into the

control unit, since this could damage the

electronic elements. Clean the outside of the

box only with a damped cloth. Make sure that

you have unplugged the unit before.

Only when pulling the mains cable, you can

ensure that the device will be completely dis-

connected from mains. Check the mains cable

regularly for damages and in case of such, it

has to be exchanged or repaired by an au-

Safety Instructions

thorized service center.

Prevent your hair from wrapping itself around

moving parts. If applicable, wear a hair net.

When working with materials, which might

create dust or moisture, use a drilling unit with

suction or spray technique. Wear a nose and

mouth protection. Always follow the safety

instructions, provided by the manufacturer of

the materials being formed and used.

For safety reasons you must always wear dis-

posable gloves and protective glasses when

operating this unit. In addition, a face mask

conforming to EN 14683 type IIR or EN 149

FFP 2 must also be worn.

Ensure that the patient’s foot and the

handpiece are held firmly in place during the

operation. To prevend injury, work with

extreme caution on the foot of the patient, and

use only light pressure.

To ensure that the bur/tool sits firmly in the

chuck, do not work with tools which:

•have an oily shaft,

•are worn,

•are bent.

Before using the equipment, assure that

•the tool can be pushed far enough into the

Safety Instructions

chuck (test this with a dipstick and clean if

necessary),

•the inserted tool sits properly in the chuck

and will not cant/jam while clamping it,

•the tool is approved for using it at the max-

imum speed (see manufacturer’s instruc-

tions) or only use the speed required by the

instrument,

•the tool is absolutely dry.

For safety reasons do not change the tool

while the motor is running.

Switch off the unit immediately if

•the bur comes off during the treatment it-

self.

•the motor blocks during the treatment.

Only use the suction function, if you have in-

stalled the suction filter. Check this filter every

10 operating hours. If it is full, please ex-

change it. A filter should be exchanged at

least after 50 operating hours.

Never use the suction to vacuum any liquids

(or air/water fog which contains particles of

liquids).

Always follow the operating instructions. Do

not carry out any repairs, modifications or

maintenance work yourself. This is only to be

Safety Instructions

accomplished by an authorized specialist. The

mains cable may also only be changed by the

manufacturer, or an authorized specialist.

Maintenance records may be supplied to re-

pair workshops and trained technicians upon

request. Never remove the housing, especial-

ly not while the equipment is plugged into the

socket, since some components are under

electric voltage. Any unauthorized or improper

handling (e.g. trying to repair the unit) of the

equipment will immediately nullify the guaran-

tee/warranty and any other liabilities of the

manufacturer.

Cleaning & Disinfection

The device is designed to be compatible with rotating in-

struments which do not penetrate the skin or mucosal or

inadvertently may still cause injuries. For this application please

adhere to the cleaning and disinfection instructions provided be-

low. After every treatment please carry out the following steps:

•Remove the rotating tool (e.g. bur, capper etc.) first. Then

handle the tool according to the manufacturer’s instructions.

•Remove tissue remains by wiping off the unit with a mildly

moistened paper cloth. Afterwards clean all surfaces with dis-

infection cloth (e.g. Mikrozid AF Tücher of Schülke and Mayr).

Please read through the instructions

carefully before using the unit and

carefully note the safety advice.

Always keep this manual accessible

to any users of the drill.

Area of Application

This device should only be used by

person who have completed a foot

care qualification. Before use the

operator should familiarize with the

device by reading this manual or

being instructed by another.

The device must only be used in

closed spaces. It may be used in

hospitals, in a commercial environ-

ment or in homes. The device is not

intended for use in operating rooms.

The control unit can be set up in a

cabinet or can be used as a porta-

ble unit (e.g. in a carry case). It is

suitable for the following scopes:

•foot care (milling, trimming and

polishing),

•manicure (grinding, milling and

polishing works).

The devise is determined of

operating rotating

instruments, which will not

penetrate the skin or

murcous membrane if used

appropriate, but could

evoke damages accidently.

Caution: In the area of

pedicure you have to work

with suction techniques.

Operation

The working area must conform to

the conditions described. Set up the

unit in such a way, that the air slits

are not blocked and the extracted

air can escape well. To guarantee

unhindered air flow there must a

gap of at least 12 cm to the right of

the device.

Position the device so that the op-

erating buttons are easy to reach

and the outlet of the hose is a max-

imum distance of 60 cm from the

patient's foot. The unit should be

30 - 90 cm from the floor.

Before First Use

If you have a foot switch, insert its

plug into the port on the right of the

device which displays this symbol

Check that the filter bag and dust

filter are correctly fitted. Ensure that

the tool is fixed.

On the left side in the back of the

device you will find the main power

switch. Press this switch to turn the

unit on.

The device is now on standby. Pick

up the handpiece. Should the

handpiece be twisted by the hose

you can adjust that at the control

unit.

To use the handpiece and suction

function press the button (9) on the

front of the unit.

Application

Operation Steps

In the following section the order in

which you should use the device is

described. Additionally, the individ-

ual steps will be explained in detail.

Read the complete manual before

use.

After connecting the device to the

power press the standby button (9)

to make it start rotating. Use the (3)

and (4) buttons to select a rotation

speed. Manufacturers often provide

recommendations for optimal rota-

tion speeds. However, it is im-

portant that you never exceed the

maximum recommended rotation

speed.

You can now choose a rotation

direction using the button (6). The

most commonly used direction is

clockwise. Most milling instrument

(steel instruments with steel cutters)

are optimised for clockwise use.

The rotation direction is irrelevant

for diamond cutters and high-grade

corundum sanders in terms of effi-

ciency. Working anti-clockwise can

be beneficial if, for example, the

dust obscures your field of vision

when working clockwise.

Switch on the suction with button

(2). Using buttons (1) and (2) you

can adjust the intensity of the suc-

tion. After choosing a rotation speed

and suction power you can start

working. If you want to take a break

or finish the job, press the standby

button (9). The handpiece motor

and suction will turn off. The hand-

piece can now be placed in its

holder on the right of the unit. Alter-

natively, you can switch the device

to standby by pressing the button

on the foot switch.

We recommend you disconnect the

device from the mains power supply

if is not going to be used for a while.

This will save electricity. The mains

plug must also be removed when it

comes to retiring the device.

Application

Work Positioning

The following images are examples

of how to work on various parts of

the foot. Always make sure that the

foot is firmly gripped and that you

can work freely and without strain.

Application

Suction

Switch on the suction with button

(2). The suction output can be regu-

lated in 5 levels. You will see the

selected level in the display. Level 0

would mean that the suction is

turned off.

In case the suction motor over-

heats, the unit will switch off auto-

matically. Leave the unit to cool off

for a while before starting it again.

Should the same failure appear

again, please return the unit to your

supplier for inspection.

Exchange Micro Filter

When changing the filter, it

is advisable to wear a face

mask conforming to EN

14683 type IIR or EN 149 FFP 2.

Only operate the unit with a suction

filter assembled. Control the filter

bag after every 10 operating hours.

Replace a full filter bag immediate-

ly, but no later than FC appears on

the display. You will receive this

message every 50 hours of opera-

tion in the suction mode.

You can read the operating time

since the last filter change by press-

ing and holding button (6) while

pressing the power button at the

same time. First, the five-digit num-

ber of the software version of your

device appears, then the operating

time since the last filter change is

displayed.

Application

At first, unfold the paper of the pa-

per filter (art. 5115) bag and push

your finger into the opening in the

front.

Pull out the lid of the dust chamber

and remove the old filter.

Hold the filter in the middle to pre-

vent it from bending and sliding off.

As an option you may also use the

micro filter (art. 5179) instead of

paper filter (art. 5115).

After the filter bag has been

changed, the operating time must

be set to zero. To do this, set the

device to standby by pressing but-

ton (9). Now hold down button (2)

for five seconds until FC appears in

the display.

Exchange Control Unit Filter

This filter (art. 3752) has to be ex-

changed after every 200 operating

hours. Remove the old filter and

place the new one in its holder (see

picture below).

Application

Clamping the Bur/Tool

The handpiece is equipped with a

chuck, which can hold all burs with

a diameter of 2.35 mm (this is the

diameter usually used for tools in

podiatry). To open the chuck, push

the knob forward with your thumb

and leave it there.

Now insert the tool as far as possi-

ble. Pull back the knob and the tool

will be firmly clamped.

For security reasons, only

change the tool if the

handpiece is turned off.

Setting up the Speed

Hold the handpiece (incl. tool) in

your hand or store it in the hand-

piece holder attached to the side of

the control unit. Switch on the unit

with button (9). Now you can also

set the speed with buttons (1) and

(2) and choose its direction of rota-

tion with button (6).

When the device is brought

out of standby mode it will

run with the rotation speed

and suction power used last. Take

care to not start the mill at an overly

high rotation speed. Select the re-

quired rotation speed before chang-

ing the milling tool.

Foot Switch (art. 0970)

Only use the original hadewe foot

switch, to avoid any damages. In-

sert the plug of the foot switch into

the socket with the symbol . If

you press the foot switch for a long-

er period, you will switch on/off the

complete control unit.

Maintenance & Care

Cleaning the Chuck

In the process of time, some dirt

might collect itself within the hand-

piece and might affect its functions.

Therefore, the chuck has to be

cleaned monthly.

How to remove the chuck

Screw off the top of the handpiece

with the spanner shown in the pic-

ture.

Now clean the inside of the hand-

piece and the top with the brush.

For opening the chuck, push the

button forward.

Set the screw spanner (wrench) on

the axle and hold it tight. Now use

the front of the second spanner to

unscrew the chuck.

To assemble the chuck, follow the

steps in reverse order. Make sure

that the chuck is opened during the

assembly (the handpiece button

must be in forward position) and is

firmly applied afterwards.

How to clean the chuck

Soak the chuck in ethyl alcohol or a

cleaning liquid for tools. Clean the

slits of the chuck with the brush.

Use the brush to remove all dirt

residues from the drill-hole of the

chuck:

Maintenance & Care

Rinse the chuck very well, and

make sure you let it dry well after-

wards. Cover your index finger with

a very little amount (just a drop) of

oil and rub in between your thumb

and index finger. Dab off the oil until

your fingers is only covered with a

very thin film of oil. Now move the

chuck in between your thumb and

index finger. There should be only a

very thin film of oil left on the chuck.

Please act according to the saying:

Less is more.

Handling Instructions

Never put the handpiece into

any kind of liquid, and never

oil or grease the handpiece.

Clean its surface with a damped

cloth. Pay attention, that no

moisture or liquid enters the

handpiece. Never use spray

disinfection.

Never put any wet burs or

instruments into the

handpiece. Its moisture

could damage the interior parts of

the handpiece.

Any materials used by

hadewe prevend a formation

of rust. In cases in which a

rust infestation was found within the

handpiece, thorough inspections

and examinations always have

proved that the rust had a foreign

origin (which was usually caused by

the tools used in these circum-

stances). Even in high-grade steel

instruments of well known

manufacturers, formation of rust

can appear, e.g., through wrong

treatment with chemical cleaning

and disinfection liquids. This

extraneous rust affects internal

parts of the handpiece in form of

rust bloom and causes pitting.

Therefore, when you not working

with the handpiece, always remove

the bur/tool from it.

Always make sure that you

do not let the handpiece fall

down or exposes it to any

shocks. The ball bearings and the

motor could be damaged by this.

Only work with tools, which are

flawless. Do not work with tools

which

- are bent or out of balance,

- whose shaft is worn out or

- are rusty.

Working with faulty tools will

cause a stronger vibration of

the handpiece. A damage of

the ball bearings, clamping tech-

nique or motor could be the conse-

quence.

Working with high pressure

will not improve the outcome

of your work, since the mo-

tor will even be slowed down. A

second disadvantage is the strong-

er impact on the ball bearings and

the motor, which will shorten their

life span in the long run.

In case of sending the de-

vice by mail remove the dust

filter before.

Only suck up dust or milling

waste, never suck up larger

particles such as small bits

of cotton wool as this may be get

caught in the handpiece and lead to

blockages.

Troubleshooting

Handpiece vibrates, is very noisy

and/or becomes warm in the

front part.

Use of bent burs/tools. →Use a

different bur/tool to test this. The

bur/tool itself can be tested with

the hadewe Bur Shaft Tester

(art. 4990) to see if it is bent.

Maximum allowed speed of the

tool was exceeded, which

caused a stronger vibration. →

Pay attention to the tool (e.g.

bur, capper and instrument)

manufacturer’s handling details.

Bur/tool can be inserted only

with difficulty or not at all.

Use of bent burs/tools. →Use a

different bur/tool to test this. The

bur/tool itself can be tested with

the hadewe Bur Shaft Tester

(art. 4990) to see if it is bent.

Chuck is dirty. →Clean the

chuck according to the instruc-

tions in the manual.

Bur does not clamp or does not

spin.

Chuck is not tightened well. →

Tighten the chuck firmly accord-

ing to the instruction in the man-

ual.

Knob of the handpiece cannot be

moved easily.

Chuck is dirty. →Clean the

chuck according to the instruc-

tions in the manual.

Rubber under the knob is tilted. →

Turn rubber about 90°.

Unit does not work at all.

Check, if the main switch of the

unit is turned on at the side of

the unit.

Foot switch is used constantly or

faulty. →Pull out the socket of

the foot switch to see if this is

the cause.

Pull out the mains plug to reset

the device.

The unit shows different sound

levels at different sites of use.

The sound level varies accord-

ing to the surroundings of the

unit. If you set up the unit direct-

ly in front of a wall, the sound is

reflected stronger, as if it would,

while standing further away from

a wall.

Handpiece motor stutters shortly

(approx. 1 sec) when turning unit

on.

In very rare cases this effect did

appear. It will not harm or dam-

age the device.

Suction function doesn't work.

The suction motor will turn off

automatically if it overheats. Let

the device cool down before us-

ing it again. Send the device off

for inspection if this occurs re-

peatedly.
