Saw chain and guide bar Oiling
Manual oiling systeM (20v only)
This chain saw is equipped with a manual
oiling system that keeps the saw chain and
guide bar lubricated. Slowly press the primer
bulb (15) on the oil cap (14) three times
before making each cut. Hold the primer bulb
down for 1 second each time. The oil level
indicator (16) shows the level of the oil in
the chain saw. If the oil level is less than a
quarter full, remove the battery from the chain
saw and refill with the correct type of oil.
auto oiling systeM (40v only)
This chain saw is equipped with an auto
oiling system that keeps the saw chain and
guide bar constantly lubricated. The oil level
indicator (16) shows the level of the oil in
the chain saw. If the oil level is less than a
quarter full, remove the battery from the chain
saw and refill with the correct type of oil.
note:
Use a high quality bar and chain
oil for proper chain and bar lubrication. As
a temporary substitute, a non-detergent
SAE30 weight motor oil can be used. 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 chain saw.
filling tHe oil reservoir
• Remove the oil cap (14) and fill the
reservoir with the recommended chain oil
until the oil level has reached the top of
the oil level indicator (16).
• Refit the oil cap.
• Periodically switch the chain saw off and
check the oil level indicator to ensure the
bar and chain are being properly oiled.
transporting saw
• Always remove the battery from the tool
and cover the guide bar (4) with the
scabbard (9) (figure i) when transporting
