4. Check saw chain tension, adjust if needed.
5. Do not over‑tension the saw chain as this will lead to
excessive wear and will reduce the life of the guide bar
and saw chain. Overtensioning also reduces the amount
of cuts you will get per battery charge.
6. Once saw chain tension is correct, tighten bar lock nut
until snug.
7. A new chain stretches slightly during the first few hours
of use. It is important to check the tension frequently
(after disconnecting battery remove the battery pack)
during the first two hours of use.
Chain Oiling (Fig. I)
1. A high quality bar and chain oil or SAE30 weight motor
oil should be used for saw chain
lubrication. The use of a vegetable based bar and chain
oil is recommended when pruning trees. Mineral oil is
not recommended because it may harm trees. Never
use waste oil or very thick oil. These may damage your
pole saw.
2. Lubricate the whole saw chain evenly before each
use as shown in Figure I. Also lubricate the saw chain
whenever replacing a fully discharged battery with a fully
charged one.
