Practical Advice

u Exercise caution when cutting slots in structural walls;

see the "Information on structural design" section.

u Do not load the power tool so heavily that it comes to a

stop.

u If the power tool has been subjected to a heavy load,

continue to run it at no-load for several minutes to

cool down the accessory.

u Work with cutting depths greater than 20 mm in hard

materials, e.g. concrete, over several work opera-

tions, so as not to overload the motor.

u Clamp the workpiece if it is not secure under its own

weight.

u Diamond cutting discs become very hot while work-

ing; do not touch them until they have cooled.

Protect the cutting disc against impact, shock and grease.

Do not subject the cutting disc to lateral pressure.

Do not attempt to reduce the speed of a diamond cutting

disc coming to a stop by applying pressure from the side.

For cutting especially hard material, e.g., concrete with high

pebble content, the diamond cutting disc can overheat and

become damaged as a result. This is clearly indicated by cir-

cular sparking, rotating with the diamond cutting disc.

If this happens, stop cutting and allow the diamond cutting

disc to cool down by running the power tool for a short time

at maximum speed with no load.

u The cutting discs sharpen themselves. A noticeably de-

creasing work rate and sparking all around the rim of the

disc are indications of a cutting disc that has become

blunt. In this case, sharpen the cutting disc by making

short cuts in abrasive material (e.g. sandstone). Sporadic

sparking is normal when working on stone and is there-

fore not a problem.

Cutting Process (seefigureJ)

Hold the power tool by the auxiliary handle(3) and the

handle(4).

When cutting metal, make sure that the valve(16) is

closed.

Always use water cooling when cutting into concrete

(seefigureH).

– Attach the adapter(18), together with the water hose,

firmly to the hose connector(17).

– Set the water flow using the valve(16) when the power

tool is switched off.

Note: Maximum permissible water pressure: 6.2bar

u Check the components of the water connection(17)

before you use the power tool. Never use damaged

parts.

u Prevent water from penetrating into the power tool

and keep it away from persons in the work environ-

ment.

– Open the water supply and the valve(16) on the power

tool.

– Ensure that the protective guard(5) is in the correct posi-

tion(see "Aligning the Protective Guard (seefigureF)",

page22).

– Switch the power tool on(see "Switching On and Off

(seefigureG)", page23).

– Slowly and carefully plunge the cutting disc into the work-

piece.

– Switch the power tool off once you have finished the cut.

– Close the valve(16) and the water supply.

Cutting Direction

The power tool must always work in an up-grinding motion.

Otherwise there is a risk that it will be pushed uncontrolled

out of the cut.

Information on structural design

Recesses in load-bearing walls are subject to country-spe-

cific regulations. These regulations must be observed under

all circumstances. Seek advice from the responsible struc-

tural engineer, architect or construction supervisor before

starting work.

Troubleshooting

Error Cause Solution

Power tool cannot be

switched on

Battery is not inserted or is discharged Replace or charge battery

Power tool and battery are outside the per-

missible operating temperature

Establish the permissible operating temperat-

ure (see "Technical Data", page20)

Power tool working, but with

interruptions

Battery is almost empty Replace or charge battery

Internal error Send the power tool to an authorised after-

sales service centre for Bosch power tools

Power tool only working for a

short time

Battery is almost empty Replace or charge battery

Strong vibrations Cutting disc is worn or is out of balance Replace the cutting disc
