elling" position. With this, the tool holder is locked.

Inserting screwdriver bits (see figure I)
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
A universal holder (22) with SDS-plus shank (accessory) is
required to work with screwdriver bits.
– Clean and lightly grease the insertion end of the shank.
– Insert the universal holder into the tool holder while turn-
ing it until it locks automatically.

– Insert a screwdriver bit in the universal holder. Only use
screwdriver bits that fit the screw head.
– To remove the universal holder, slide the locking sleeve

from the tool holder.
Hanging up the power tool (see figure J)
You can use the utility hook (17) to attach the power tool to
a suitable suspension device.
– Fold the utility hook (17) upwards.
– Check the utility hook (17) for damage or deformation.
Do not use the utility hook (17) if it is damaged, de-
formed or no longer firmly secured to the power tool.
– Use the utility hook (17) to attach the power tool to a sus-
pension device.
To avoid damage or injury, the suspension device must
not be attached above walkways or immediate work
areas.
The utility hook is intended solely for the purpose of
hanging the power tool, including fitted accessories.
– Fold the utility hook (17) in again when you want to begin
work with the power tool.
Never use the utility hook (17) as a fall protection sys-
u
tem.
Never attach the fall protection system to the utility
hook.
Attaching the Fall Protection System (see figure K)
Note: A fall protection system (24) that is suitable for the
weight of the entire system should be used to prevent the
power tool from falling. The maximum permitted length of
the fall protection system is 1.8 m. Please always refer to the
permitted attachment area (23) on the power tool.
It is best to use the fall protection system with a tape loop se-
cured by an anchor knot or a fall protection system with fall
damper.
Please always refer to the operating instructions when at-
taching the fall protection system (24).
Always secure the opposite side of the fall protection
u
system to a stable structure (e.g. a building or scaf-
folding) and never to the user.
The fall protection system must be able to move freely
and may only be attached to the power tool at the
fixed anchorage point (25) and in the permitted at-
Bosch Power Tools
tachment area (23) .
Select the fixed anchorage point (25) such that the
power tool can fall freely into the fall protection sys-
tem without wrapping around or putting the user at
risk of harm in the event of a fall.
Never use the utility hook (17) as a fall protection sys-
tem.
Never attach the fall protection system to the utility
hook.
Never use the fall protection system on a power tool
which has been fitted with the GDE 18V-26 D or GDE
16 Plus dust extraction attachments.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
