Noise/vibration information
Noise emission values determined according to
EN 62841‑2‑14.
Typically, the A-weighted noise level of the power tool is:
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 62841‑2‑14:

a = 4,5 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.
Fitting
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Changing the tool
Take care when changing the planer blade. Do not pick
u
up the planer blade by the cutting edges. You may be
injured by the sharp cutting edges.
Use only original Bosch HM/TC planer blades. The hard
metal (HM/TC) planer blade has two cutting edges and can
be turned. If both cutting edges become blunt, the planer
blade (14) needs to be changed. The HM/TC planer blade
must not be resharpened.
Removing the planer blade (see figure A)
To turn or replace the planer blade (14), turn the blade head
(11) until it is parallel to the planer base plate (9).
➊ Loosen the two fastening screws (13) using the hex key
(15) (approx. 1–2 turns).
➋ If necessary, loosen the clamping element (12) by lightly
striking it with an appropriate implement, e.g. a wooden
wedge.
➌ Use a piece of wood to push the planer blade (14) to the
side and out of the blade head (11).

Fitting the planer blade (see figure B)
The guide groove on the planer blade ensures a constant,
even height setting when changing or turning the blade.
If necessary, clean the knife seat in the clamping element
(12) and the planer blade (14). When fitting the planer
blade, ensure that it is securely seated in the mounting guide
of the clamping element (12) and is aligned flush with the
side edge of the planer base plate (9) at the rear. Then
tighten the two fastening screws (13) with the hex key (15).
Note: Check that the fastening screws (13) are firmly
tightened before start-up. Turn the blade head (11) by hand
and ensure that the planer blade is not brushing against any-
thing.
Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Clean the chip ejector (1) regularly. Clean a clogged chip
ejector using a suitable tool, e.g. a piece of wood, com-
pressed air, etc.
Do not allow the chip ejector to come into contact with
u
your hands. You may be injured by rotating parts.
Always use an external dust extraction device or chip/dust
bag to guarantee optimum suction.
External dust extraction (see figure C)
An extraction hose (dia. 35 mm) (16) (accessory) can be
connected to the chip ejector on either side (PHO 2000) or
a single side only (PHO 1500).
Connect the dust extraction hose (16) to a dust extractor
(accessory). You will find an overview of how to connect
various dust extractors at the end of these operating instruc-
tions.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.
Self-generated dust extraction (see figure C)
A chip/dust bag (accessory) (17) can be used for smaller
jobs. Insert the dust bag nozzle of the chip/dust bag firmly
