Checking the Flow of Bar
and Chain Oil
Service Interval:
Before each use or daily
1.
Prepare to use the pole saw; refer to
Using the Pole Saw (page 14)
.
2.
To ensure that oil is flowing to the chain, point
the nose of the pole saw a few inches from a
surface (e.g. paper, cardboard, a stump) and
run the pole saw; you should be able to see a
light spray of oil on the surface (

Figure 16
1.
Run the pole saw a few
inches from a surface.
2.
If the oil is flowing, it will
spray off the chain and
accumulate.
3.
If oil is not flowing, ensure that there is oil in the
tank and that the area under the side cover is
clean; refer to
Checking the Oil Level and Adding
Bar and Chain Oil (page 17)
and
Guide Bar, Chain, and Drive Sprocket (page 20)
.
Adjusting the Chain
Tension
Service Interval:
Before each use or daily
After each battery drain cycle
Ensure that the chain is properly tensioned.
A loose chain shortens the life of the drive sprocket
and the guide bar and may cause the chain to fall off.
An overtightened chain overheats the guide bar and
chain, causing rapid wear, and may burn out the motor
or break the chain.
The chain tension is correct when you are able to use
a gloved hand to pull the chain smoothly around the
guide bar. The chain should remain in contact with
the bottom edge of the guide bar.
Also, check the chain tension of a new chain after a
few cuts; a new chain usually stretches and requires
adjustment after a few cuts.
DANGER
Contact with the pole saw teeth can cause
serious personal injury.
•
Remove the battery pack before adjusting
or maintaining the pole saw.
•
Always wear gloves when adjusting or
maintaining the pole saw.
