Working Advice

Before Cutting

Before starting operation and periodically during cutting,
carry out the following checks:
– Is the pole pruner in a fail-safe condition?
Troubleshooting
Pole pruner
Problem
Possible Cause
Saw chain dry
No oil in reservoir
Oil passage clogged
Saw chain/guide bar
No oil in reservoir
hot
Vent in oil filler cap (3) clogged
Oil passage clogged
Chain tension too high
Dull saw chain
Overload protection actuated
Battery thermal protector actuated
Pole pruner rips, vi-
Saw chain tension too loose
brates, does not saw
Dull saw chain
properly
Saw chain worn out
Saw chain teeth are facing in the wrong direction Reassemble with saw chain in correct direction
Too much force applied
Too few cuts per bat-
Battery thermal protector actuated
tery charge
Pole pruner cuts out
Chain tensioned too tight
when sawing
Over pressure applied to saw during cutting
New saw chain
Hard wood
Wood is wet
F 016 L94 061 | (23.12.2020)
– Is the oil reservoir filled? Check oil level gauge prior to
starting and regularly during operation. Refill oil when the
oil level has reached the bottom edge of the oil level indic-
ator. The oil tank filling will last approx. 15 minutes, de-
pending on sawing intensity and stops.
– Is the saw chain properly tensioned and sharp?
General behaviour (see figure N)
The chain must be running at full speed before it makes con-
tact with the wood. Use the tip protector to support the un-
dercutting.
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 pre-
vent damaging the tree.
The tip protector is designed to support the undercutting of
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.
Corrective Measure
Refill oil (article number: 2 607 000 181)
Clean oil passage
Refill oil (article number: 2 607 000 181)
Clean oil filler cap (3)

Tension saw chain
Sharpen saw chain or replace
Switch machine on again.
Allow battery to cool down and restart
Tension saw chain
Sharpen saw chain or replace
Replace saw chain
Reduce force
Allow battery to cool down and restart
Retension saw chain
Reduce force applied to saw during cutting
