Assembly
Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
Battery Charging (see figure A)
Use only the battery chargers listed on the accessories
page. Only these battery chargers are matched to the lith-
ium ion battery of your power tool.
Note: The battery is supplied partially charged. To ensure full
capacity of the battery, completely charge the battery in the
battery charger before using your power tool for the first time.
The Lithium-Ion battery can be charged at any time without
reducing its service life. Interrupting the charging procedure
does not damage the battery.
The Lithium-Ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
Do not continue to press the On/Off
WARNING
switch after the machine has been au-
tomatically switched off. The battery can be damaged.
To remove the battery 7 press the unlocking buttons 8 and
pull out the battery downwards. Do not exert any force.
The Allen key 12 required for replacement of the planer blade
is located inside the machine and should always be stored
there.
The battery is equipped with a NTC temperature control
which allows charging only within a temperature range of be-
tween 0 °C and 45 °C. A long battery service life is achieved
in this manner.
Observe the notes for disposal.
Battery Charge-control Indication (only for 3.0 Ah bat-
tery) (see figure B)
The three green LEDs of the battery charge-control indicator
14 indicate the charge condition of the battery 7. For safety
reasons, it is only possible to check the status of the charge
condition when the machine is at a standstill.
Press button 13 to indicate the charge condition. This is also
possible when the battery 7 is removed.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Flashing light 1 x green
When no LED lights up after pushing button 13, then the bat-
tery is defective and must be replaced.
Bosch Power Tools
Changing the Tool
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.
Use only original Bosch carbide blades (TC).
The carbide blade (TC) has 2 cutting edges and can be re-
versed. When both cutting edges are dull, the planer blade 18
must be replaced. The carbide blade (TC) may not be resharp-
ened.
Disassembling the Planer Blade(s) (see figure C)
To reverse or replace the planer blade 18, rotate the blade
drum 15 until it is parallel to the planer base plate 10.
Loosen the two fastening screws 17 with the Allen key
12 by approx. 1 – 2 turns.
If necessary, loosen the clamping element 16 by giving it
a light blow with a suitable tool (e.g. a wooden wedge).
Push the planer blade 18 sidewards out of the blade
drum 15 with a piece of wood.
Assembling the Planer Blade(s) (see figure D)
The guide groove of the planer blade always ensures continu-
ous height adjustment when replacing or reversing it.
If required, clean the blade seat in the clamping element 16
and the planer blade 18.
When assembling the planer blade, ensure that it is seated
properly in the blade holder of the clamping element 16 and
aligned flush at the side edge of the rear planer base plate 10.
Afterwards tighten the 2 fastening screws 17 again with the
Allen key 12.
Note: Before restarting, check if the fastening screws 17 are
tightened well. Rotate the blade drum 15 by hand and ensure
that the planer blade does not graze.
Dust/Chip Extraction
Dusts 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 dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
Capacity
– As far as possible, use a dust extraction system suita-
≥2/3
ble for the material.
≥1/3 – Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
<1/3
Observe the relevant regulations in your country for the
Reserve
materials to be worked.
Clean the chip ejector 1 regularly. Use a suitable tool (e.g., a
piece of wood, compressed air, etc.) to clean a clogged chip
ejector.
Do not reach into the saw dust ejector with your hands.
They could be injured by rotating parts.
To ensure optimum extraction of dust/chips, always work
with external dust extraction or a chip/dust bag.
