Dust/Chip Extraction - Bosch GHO 14,4 V Professional Originalbetriebsanleitung

Assembly
Before any work on the machine (e. g. main-
tenance, changing the tool, etc.) as well as
during its transport and storage, lock the
On/Off switch in the off position. There is
danger of injury when the On/Off switch is un-
intentionally actuated.
Battery Charging (see figure D)
A battery that is new or has not been used for a
longer period does not develop its full capacity
until after approx. 5 charging/discharging cycles.
To remove the battery 7, press the unlocking but-
tons 8 and pull the battery out of the machine to
the rear. Do not exert any force.
The Allen key 17 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 tem-
perature range of between 0 °C and 45 °C. A long
battery service life is achieved in this manner.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Observe the notes for disposal.
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 planer
blades.
Use only original Bosch carbide blades (TC).
The carbide blade (TC) has 2 cutting edges and
can be reversed. When both cutting edges are
dull, the planer blade 16 must be replaced. The
carbide blade (TC) may not be resharpened.
Disassembling the Planer Blade(s)
(see figure A)
To reverse or replace the planer blade 16, rotate
the blade drum 13 until it is parallel to the planer
base plate 12.
Bosch Power Tools
Loosen the two fastening screws 15 with the
Allen key 17 by approx. 1 – 2 turns.
If necessary, loosen the clamping element 14
by giving it a light blow with a suitable tool
(e.g. a wooden wedge).
Push the planer blade 16 sidewards out of
the blade drum 13 with a piece of wood.
Assembling the Planer Blade(s) (see figure B)
The guide groove of the planer blade always en-
sures continuous height adjustment when re-
placing or reversing it.
If required, clean the blade seat in the clamping
element 14 and the planer blade 16.
When assembling the planer blade, ensure that it
is seated properly in the blade holder of the
clamping element 14 and aligned flush at the side
edge of the rear planer base plate 12. Afterwards
tighten the 2 fastening screws 15 again with the
Allen key 17.
Note: Before restarting, check if the fastening
screws 15 are tightened well. Rotate the blade
drum 13 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. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.
