Noise/Vibration Information
Noise emission values determined according to
EN IEC 62841-2-6.
Typically, the A-weighted noise level of the power tool is:
Sound pressure level 95 dB(A); sound power level
102 dB(A). Uncertainty K=3 dB.
Wear hearing protection
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to
EN IEC 62841-2-6:
2
Chiselling: a = 15.5 m/s , K = 1.5 m/s
h
The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Auxiliary Handle
Do not operate your power tool without the auxiliary
u
handle (7).
You can swivel the auxiliary handle (7) to any angle for a safe
work posture that minimises fatigue.
– Turn the lower gripping end of the auxiliary handle (7) an-
ticlockwise and swivel the auxiliary handle (7) into the re-
quired position. Then, turn the lower gripping end of the
auxiliary handle (7) clockwise to retighten.
Changing the Tool
With the SDS-max tool holder, you can change the applica-
tion tool simply and easily without additional aids.
The dust protection cap (1) largely prevents the penetration
of drilling dust into the tool holder during operation. When
inserting the tool, make sure that the dust protection cap (1)
does not become damaged.
Bosch Power Tools
Replace a damaged dust protection cap immediately.
u
It is recommended that you have use an after-sales
service for this.
Inserting the application tool (see figure A)
– Clean and lightly grease the shank of the application tool.
– Push the locking sleeve (2) back and insert the applica-
tion tool by turning it into the tool holder. Release the
locking sleeve (2) to lock the application tool.
– Check the latching by pulling the tool.
Removing the application tool (see figure B)
2
– Push the locking sleeve (2) back and remove the applica-
tion tool.
Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Operation
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Starting Operation
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Switching On and Off
– To start the power tool, press and hold the on/off switch
(5).
– Press the lock-on button (4) to lock the on/off switch (5)
in this position.
– To switch off the power tool, release the on/off switch
(5); or, if the switch is locked with the lock-on button (4),
briefly press the on/off switch (5) and then release it.
At low temperatures, the power tool will take a certain
amount of time to reach its full impact performance. You can
shorten this warm-up time by tapping the power tool's inser-
ted application tool on the ground once.
