Starting Operation

For Your Safety
Warning! Switch off, remove the isolator switch and
u
the battery before adjusting or cleaning. The same ap-
plies when the cable to the switch in the handle is
damaged, cut or entangled.
The blade continues to rotate for a few seconds after
u
the machine is switched off.
Caution: Do not touch the rotating blade.
u
Use only the chargers listed in the technical data. Only
u
these chargers are matched to the lithium-ion batteries of
your product.
Charging the Batteries
The batteries are equipped with temperature monitoring
that allows charging only in the temperature range between
0 °C and 35 °C. In this manner, high batteries service life are
achieved.
Note: The batteries are supplied partially charged. To ensure
full batteries capacity, completely charge the batteries in the
battery charger before using for the first time.
The lithium-ion batteries can be charged at any time without
reducing its service life. Interrupting the charging procedure
does not cause damage to the batteries.
The "Electronic Cell Protection (ECP)" protects the lithium-
ion batteries against deep discharging. When the batteries
are empty, the product is switched off by means of a pro-
tective circuit: The product no longer operates.
Do not continue to press the On/Off switch after an auto-
matic shut-off of the product. The batteries could become
damaged.
Observe the notes for disposal of the batteries.

completely discharged. Always use batteries with the
same charge level and never combine full and part-
charged batteries as the run time will always be dic-
tated by the least charged battery.
Note: Using unsuitable batteries can lead to malfunctions or
damage the machine.
Insert the charged batteries. Ensure that the batteries are
fully inserted.
To remove the batteries from the machine, press the battery
unlocking button and pull the batteries out.

Working Advice

Cutting Capacity (Battery Operating Duration)
The cutting capacity (battery operating duration) depends
on lawn properties, such as grass density, moisture content,
grass length and height of cut.
Switching the machine on and off frequently during cutting
will also reduce the cutting capacity (battery operating dura-
tion).
To improve the cutting capacity (battery operating dura-
tion), it is recommended to cut more frequently, increase
the cutting height and walk at an appropriate pace.
The example below shows the connection between cutting
height and cutting capacity with regard to two batteries.
Cutting Conditions
6cm
4cm
Very thin, dry grass
Cutting capacity
2 x 4.0 Ah batteries up to 500 m
2 x 6.0 Ah batteries up to 650 m
To increase the run time an additional battery can be pur-
chased from an authorised customer service agent for Bosch
garden products.
Corrective Measure
Contact Bosch customer service agent
Recharge both batteries
Allow to cool/warm
Max. allowed grass height 30 cm on highest
height-of-cut setting
Allow motor to cool and increase height of cut
Fit correctly
