Note: If the machine should automatically switch off because

of a discharged or overheated battery, make sure to set the

machine’s On/Off switch 5 to off. Charge the battery and al-

low it to cool down before restarting the machine. Otherwise

the battery can become damaged.

Preselecting the Orbital Stroke Rate

With the thumbwheel for preselection of the orbital stroke

rate 3, you can preselect the required orbital stroke rate, even

during operation.

The required stroke rate depends on the material and the

working conditions and can be determined through practical

testing.

When sawing and cutting harder materials, e.g., wood or met-

al, it is recommended to work with orbital stroke rate “5” or

“E”; for softer materials, such as plastic, orbital stroke rate “4”

is recommended.

When sanding harder materials, e.g., wood or metal, it is rec-

ommended to work with orbital stroke rate “5”; for softer ma-

terials, such as softwood, orbital stroke rate “4” is recom-

mended.

The Eco electronics are active at the maximum orbital stroke

rate “E”: When the application tool is not subject to load, the

orbital stroke rate is automatically reduced (after approx.

1 s). The reduction extends the battery operating duration

per charge, and the reduced vibrations enable precise apply-

ing of the application tool onto the workpiece. As soon as load

is applied to the application tool again, the machine automat-

ically accelerates to the maximum orbital stroke rate.

The Eco electronics, however, are not suitable for sanding ac-

tivities. Instead, orbital stroke rate “5”, which has the same

oscillation rate as setting “E” yet without the Eco electronics,

is suitable for sanding.

Working Advice

 Wait until the machine has come to a standstill before

placing it down.

 Before any work on the machine itself, pull the mains

plug.

Note: Do not cover off the venting slots 6 of the machine while

working, as this reduces the working life of the machine.

While working with HCS tools make sure that the covering of

the tools is undamaged.

Operating Principle

Due to the oscillating drive the application tool/accessory

oscillates up to 20000 times per minute at 2.8°. This allows

for precise work in narrow spaces.

Work with low and uniform application

pressure, otherwise, the working perfor-

mance will decline and the application tool

can become blocked.

While working, move the machine back and

forth, so that the application tool does not

heat up excessively and become blocked.

Sawing

 Use only undamaged saw blades that are in perfect con-

dition. Bent or dull saw blades can break, negatively influ-

ence the cut, or lead to kickback.

 When sawing light building materials, observe the stat-

utory provisions and the recommendations of the ma-

terial suppliers.

 Plunge cuts may only be applied to soft materials, such

as wood, gypsum plaster boards, etc.!

Before sawing with HCS saw blades in wood, particle board,

building materials, etc., check these for foreign objects such

as nails, screws, or similar. If required, remove foreign ob-

jects or use BIM saw blades.

Separating

Note: When separating wall tiles take into consideration that

the application tools/accessories wear heavily when used for

longer periods of time.

Sanding

The removal rate and the sanding pattern are primarily deter-

mined by the choice of sanding sheet, the preset oscillation

rate and the applied pressure.

Only flawless sanding sheets achieve good sanding capacity

and extend the service life of the machine.

Pay attention to apply uniform sanding pressure; this increas-

es the working life of the sanding sheets.

Intensifiying the sanding pressure does not lead to an in-

crease of the sanding capacity, but to increased wear of the

machine and the sanding sheet.

For precise on-the-spot sanding of edges, corners and hard to

reach areas, it is also possible to work only with the tip or an

edge of the sanding plate.

When selectively sanding on the spot, the sanding sheet can

heat up considerably. Reduce the orbital stroke rate and the

sanding pressure, and allow the sanding sheet to cool down

regularly.

A sanding sheet that has been used for metal should not be

used for other materials.

Use only original Bosch sanding accessories.

To reduce the dust exposure and achieve better working re-

sults when sanding, use dust extraction as far as possible.

Scraping

For scraping, select a high oscillation rate.

Work on a soft surface (e.g. wood) at a flat ange, and apply

only light pressure. Otherwise the scraper can cut into the

surface.

Temperature-dependent Overload Protection

When using the machine as intended for, it cannot be subject

to overload. In case of excessive load or when not within the

permitted battery temperature range of –20 °C to +65 °C,

the machine switches off. In case of overload, the battery

charge-control indicator 4 will additionally flash red for a few

seconds.
