1.2 Safety precautions for the BMA/BMB Tool

In order to avoid incorrect handling and injury to the user or

destruction of the BMA/BMB Tool arising from this, pay

attention to the following:

• Always store these operating instructions together with

the BMA/BMB Tool.

• The BMA/BMB Tool must only e sold together with the

latest operating instructions.

• As part of their training, trainees may only operate the

BMA/BMB Tool under the supervision of an experienced

person.

• Protect the BMA/BMB Tool from frost and damp.

• Make connections to the vehicle only when the engine is

not running.

• Protect the BMA/BMB Tool from liquids like water, oil or

fuel (it is not waterproof).

• Protect the BMA/BMB Tool from heavy shock impact (do

not drop or knock over).

• Protect the BMA/BMB Tool and connection lines from hot

parts.

• Before relocation, repairs or work on the BMA/BMB Tool

that is not related to its operation: switch off the BMA/

BMB Tool and remove the power plug.

• In the event of danger, switch off the main switch and

remove the power plug.

• The BMA/BMB Tool is not designed for use with synthetic

rake fluid.

• Do not connect the BMA/BMB Tool to compressed air

using the quick coupling (17).

• Do not clean the BMA/BMB Tool using flamma le liquids.

• The BMA/BMB Tool must e transported and shipped

without rake fluid.

• Do not operate the BMA/BMB Tool without rake fluid.

• Do not fill or operate the BMA/BMB Tool with DOT 5

rake fluid (not suita le).

Safety precautions BMA/BMB-Tool

Danger notices – rake fluid

• Do not fill or operate the BMA/BMB Tool with liquids

containing mineral oil.

1.3 Dan er notices – brake fluid

O serve the following when handling rake fluid:

• Irritating to skin, eyes and respiratory system.

• In the event of contact with the eyes or skin, rinse

immediately with plenty of clean water.

• Seek medical attention immediately if rake fluid comes

into contact with the eyes or is swallowed.

• Use protective clothes, protective gloves and protective

goggles.

• Brake systems may e under (high) pressure.

• Always use suita le and compati le rake fluid. Follow

the instructions of the vehicle manufacturer.

• Never mix DOT 3, DOT 4 or DOT 5.1 (glycol- ased) rake

fluid with DOT 5 (silicone- ased).

• Brake fluid damages paint and plastic parts. Immediately

remove all rake fluid from paint and plastic parts.

• Brake fluid is hydroscopic and a sor s moisture.

Moisture in the rake system can lead to failure of the

rake system.

• Brake fluid must only e stored in sealed original

containers.

• Mop up any leaked rake fluid immediately using a cloth

and dispose of it in an environmentally friendly manner.

• O serve the data sheet and regulations of the rake fluid

manufacturer.

Safety precautions – high voltage and line voltage

1.4 Safety precautions – hi h volta e and line volta e

Failure to o serve the safety precautions with regard to

mains voltage can result in serious injury, death or damage

to the BMA/BMB Tool. Therefore o serve the following:

• Always use original ca le sets.

• Regularly check the connecting ca le for damage.

• Remove the power plug efore relocation, repair or work

on the BMA/BMB Tool.

1.5 Safety precautions – risk of injury

There is a risk of injury due to rotating parts or rolling vehicle

when working on the vehicle. Therefore o serve the

following:

• Protect vehicle against rolling away.

• Additionally, park position of automatic gear oxes to P.

• Do not reach into rotating parts when engine is running.

• Do not route connecting ca les near rotating parts.

• Check high voltage parts for damage.

2.1.1 Checkin delivery contents

Please check the delivery contents upon receiving your tool so that

complaints can e issued immediately regarding potential damage or

missing parts.

Proceed as follows to check the delivery contents:

BMA/BMB-Tool Tool description

Intended use

1. Check the package delivered to ensure that it is not damaged.

Should you identify any damage to the package, then open the package

in the presence of the delivery service and check the BMA/BMB Tool

for hidden damage. Any transport damage to the package supplied and

damage to the BMA/BMB Tool shall e registered in a damage report

y the delivery service.

2. Open the package supplied and check for completeness ased on the

delivery slip.

3. Remove the BMA/BMB Tool from the packaging.

4. Check the BMA/BMB Tool for damage and completeness.

2.2 Intended use

The BMA/BMB Tool (Brake Maintenance A or B model) is a rake

maintenance tool for filling and leeding hydraulic systems containing

rake fluid in motor vehicles, e.g. rake or clutch circuits. The BMA/BMB

Tool may only e used with DOT 3, DOT 4 or DOT 5.1 (glycol- ased) rake

fluid. Hydraulic fluid ased on mineral oil or DOT 5 rake fluid (silicone-

ased) is not suita le for the BMA/BMB Tool and must therefore not e

used. As rake fluid is very hydroscopic (a sor s and retains moisture),

the BMA/BMB Tool must e stored and operated in dry conditions.

For maintenance of the hydraulic system, the BMA/BMB Tool is connected

to the associated rake fluid reservoir using a suita le adapter. A

pressurised electric pump delivers new rake fluid from the BMA Tool or

BMB Tool to the rake fluid reservoir. The supply pressure can e

continuously adjusted from 0 to 2.8 ar. The rake fluid current pulsates

during the leeding phase of the hydraulic system. These fluctuations

ena le a complete leeding process, as even the smallest amounts of air

or moisture at the pipe connections are carried away.

After switching off the electric pump, the pressure in the rake fluid

reservoir reduces and the correct rake fluid level is automatically set.

If the rake fluid container is emptied to the minimum filling level, the

pump switches off automatically. This ensures that air never gets into the

hydraulic system.

in the hydraulic system.

3Pressure regulator

This is used to set the desired maintenance pressure of the rake

fluid.
