damaged blades may cause serious or 
fatal injuries to the operator and 
bystanders. Avoid the roots of trees! 
Large roots may jam the blades and 
damage the machine. The tree may also 
be damaged if its roots are severed.
WARNING
If the working tool or deflector is blocked 
or covered, always switch off the engine 
and ensure that the tool has come to a 
standstill before starting to clean it. 
Grass, weeds, etc. should be cleaned off 
the tool at regular intervals.
WARNING
To reduce the risk of unintentional 
rotation of the working tool and injury, 
always shut off the engine and remove 
the spark plug boot before replacing the 
soil cultivating attachment.
WARNING
The gearbox becomes hot during 
operation. To reduce the risk of burn 
injury, do not touch the gear housing 
when it is hot.
MAINTENANCE, REPAIR AND 
STORING
WARNING
Always stop the engine and make sure 
that the attachment is stopped before 
doing any maintenance or repair work or 
cleaning the power tool. Do not attempt 
any maintenance or repair work not 
described in the instruction manuals for 
your basic power tool and your soil 
cultivating attachment. Have such work 
performed at your STIHL servicing 
dealer only.
WARNING
Use only identical STIHL replacement 
parts for maintenance and repair. Use of 
non-STIHL parts may cause serious or 
fatal injury.
Wear gloves when handling or 
performing maintenance on blades.
WARNING
Never repair damaged attachments by 
welding, straightening or modifying the 
shape. This may cause parts of the 
attachment to come off and result in 
serious or fatal injuries.
Tighten all nuts, bolts and screws, 
except the carburetor adjustment 
screws, after each use.
Do not clean your machine with a 
pressure washer. The solid jet of water 
may damage parts of the machine.
Store the power tool in a dry and high or 
locked location out of reach of children.
General
The BF attachment is used as a 
cultivator for tilling the soil.
Bolo tine rotor blades are available as 
special accessories for working lighter 
soils.
Pick tines are particularly suitable for 
tilling and loosening hard or packed soil.
