Noise/Vibration Information
Sound emission values determined according to
EN 60745-2-14.
Typically the A-weighted noise levels of the product are:
Sound pressure level 86 dB(A); Sound power level 97 dB(A).
Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 60745-2-14:
2 2
a =5.5 m/s , K=1.5 m/s .

The vibration level given in this information sheet has been
measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.

Bosch Power Tools
Assembly
 Before any work on the machine itself, pull the mains
plug.
Planer Blade Selection
The power tool can be fitted with different planer blade types.
By using conversion kits (accessory), either planer blade type
(HSS or TC carbide blades) can be used, depending on the
standard equipment of the power tool.
When replacing planer blades, always replace both blades;
otherwise an imbalance can generate vibrations, which can
reduce the service life of the power tool.
Changing HSS Planer Blades
 Be cautious when replacing the planer blades. Do not
grasp the planer blades by the cutting edges. Possible
danger of injury due to the sharp cutting edges of the plan-
er blades.
Disassembling the Planer Blade(s) (see figures A – C)
– To reverse the planer blades, rotate the blade drum 13 un-
til the clamping jaw 12 is parallel to the planer base plate 8.
– Unscrew the 3 fastening screws 11 with the Torx key 10
and remove the clamping jaw 12.
– Slide the planer-blade retainer 16 together with the planer
blade 15 out of the guide groove 14 of the blade drum 13.
– Turn the blade drum by 180° and disassemble the 2nd
planer blade.
Note: Before replacing or resharpening the planer blades, re-
move the HSS planer-blade retainer 16 by loosening the fas-
tening screws 17.
Resharpening HSS Planer Blades (see figure D)
Worn or dull HSS planer blades can be resharpened with the
sharpening device 18 (accessory) and a commercially availa-
ble whetstone.
Insert both planer blades into the sharpening device and
clamp them by tightening the wing bolt. Make sure that both
planer blades are completely inserted to the stop.
Move the sharpening device with the inserted planer blades
uniformly and with light pressure across the whetstone.
Note: Never regrind the planer blades by more than 6 mm,
based on a minimum width of 23 mm. Thereafter, both planer
blades must be replaced.
Assembling the Planer Blade(s) (see figures E–F)
Before reinserting new or resharpened planer blades, clean
the blade drum 13 and the planer blades 15, if required, as
well as the HSS planer-blade retainer 16. Clean heavily
gummed planer blades with spirits or petroleum.
Note: Before assembling new or resharpened planer blades,
their correct height setting must be adjusted first.
The setting gauge 19 (accessory) is used for adjusting the
height of the planer blades. Place the planer blade 15 and the
blade retainer 16 on the setting gauge. Make sure that the
blade retainer 16 engages in the groove inteneded for this
purpose. Press the planer blade 15 against the stop and lock
the blade retainer 16 in this position with the fastening
screws 17. This will automatically adjust the correct height.
