– Replace the cap. Clean any spilled oil remaining on the tool
with a cloth.
– Make sure that the oil cap is not overtightened.
– Run pole pruner for 30 seconds to prime oil system.
Note: To allow venting of the oil reservoir, small breather
channels are provided between the oil filler cap. To prevent
leakage, ensure pole pruner is left in a horizontal flat (oil filler
cap 3 uppermost) when not in use.
Replacing the chain (see figures K + L)
 Always wear protective gloves when handling the
chain.
 Use only Bosch approved chains designed for
chainbars with 1.1 mm groove.
Undo the two screws located on the cover 22 and remove the
cover.
Lift the saw chain 1 and bar 2 off the sprocket 23.
Take the blunt saw chain 1 off the bar 2 and discard safely.
Slide the new saw chain in the slot around the chain bar.
Ensure the chain is in the correct running direction by
comparing the chain with the rotation symbol on bar.
Fit the new saw chain onto the drive sprocket 23 and chain
bar 2 over the guide fin 24, ensure that all parts are seated
properly. Re-fit the cover 22 and tighten the two fixing screws
25.
Check the tensioning before use. Tension the chain using the
tensioning screw 5 if necessary.

Operation

Switching on and off (see figure M)
To switch on the power tool, first press the lock-off switch 14
then press On/Off switch 16. Keep the On/Off switch while
operating the machine. You can let go of the lock-off switch
while the tool is switched on.
To switch off the power tool, release the On/Off switch 16.
Troubleshooting
Problem Possible Cause
Saw chain dry No oil in reservoir
Oil passage clogged
Saw chain/guide bar hot No oil in reservoir
Vent in oil filler cap 3 clogged
Oil passage clogged
Chain tension too high
Blunt saw chain
Over current protection is activated
Battery Thermal Protection operated
F 016 L81 582 | (28.2.18)
To save energy, only switch the power tool on when using it.
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the power tool is switched off by means of a protective
circuit: The tool no longer runs.
 Do not continue to press the On/Off switch after the
machine has been automatically switched off. The
battery can be damaged.
Working Advice (see figure N)

Before cutting

Before starting operation and periodically during cutting,
carry out the following checks:
– Is the pole pruner in a fail-safe condition?
– Is the oil reservoir filled? Check oil level gauge prior to
starting and regularly during operation. Refill oil when oil
level has reached the bottom edge, see through oil level
indecator. The reservoir filling will last approx. 15 minutes,
depending on sawing intensity and stops.
– Is the saw chain properly tensioned and sharp?
General behaviour
The chain must be running at full speed before it makes
contact with the wood. Use the tip protector to support the
undercutting.
Pruning straight through a tree branch from the top edge
down is appropriate for branches up to 5 cm in diameter.
Thicker branches should be pruned in three-steps, to prevent
damaging the tree. The tip protector is designed to support
undercutting branches.
Do not force the pole pruner while cutting, let the chain do the
work.
Sawing is optimized when the chain speed remains steady
during cutting.
