Oiling (Fig. A, K)

WARNING: A high quality bar and chain oil or SAE30
weight motor oil should be used for chain and bar
lubrication. The use of a vegetable based bar and
chain oil is recommended when pruning trees. Never
use waste oil or very thick oil. These may damage your
chain saw.
1. Before first use and every ten minutes of use you must
oil the product with the recommended chain oil. Open
the oiling cover 4 and insert the bottle into the oil
filling hole 17 apply pressure to the bottle once to
dispense oil.
2. This should be adequate for about 10 minutes of cutting
depending upon cutting speed and type of wood.
3. The hole feeds the oil through to the chain onto the
chain bar and an excessive amount of oil applied to
the unit could mean the oil drips from the unit around
the jaw area. This is normal and is nothing to be
concerned about.

better and safer job at the speed for which it is designed.
Excessive force will stretch the chain.
