Always remove the Battery Pack before performing any maintenance, or repairs to your Pole Saw.
Chapter 4: Maintaining Your DR PULSE 62V POLE SAW
Chain Tension
Check the Chain Tension before using the Saw when the Chain is cold. The
correct tension of a cold Chain is when there is no slack on the underside of the
Bar, the Chain is snug, but you can turn it by hand without binding.
During normal Saw operation, the temperature of the Chain will increase. The
Drive Links of a correctly tensioned warm Chain will hang approximately .050 in.
(1.25mm) out of the Bar Groove (
Figure 20
). Be aware that a Chain tensioned
while warm, may be too tight upon cooling. Check the "cold tension" before
next use.
The Chain must be re-tensioned whenever the Flats on the Drive Links hang out
of the Bar groove.
Note:
A new Chain tends to stretch so check the Chain tension frequently and re-
tension as required.
1.
Loosen the Sprocket Cover Locknut slightly to allow the Bar to move
without binding (
Figure 21
).
2.
Turn the Tension Screw clockwise to tighten the Chain as needed (
Figure
22
).
3.
Tighten the Sprocket Cover Screw and recheck Chain tension.
4.
Repeat steps 1 through 3 if needed to achieve correct Chain tension.
Bar Maintenance
When the Bar shows signs of wear, turn it over on the Saw to distribute the wear
for maximum Bar life. Feathering or burring of the Bar Rails is a normal process
of Bar wear. You should smooth such faults with a file as soon as they occur.
Replace a Bar with any of the following faults:
Wear inside the Bar Rails permitting the Chain to layover sideways.
Bent Bar
Cracked or broken Rails
Spread Rails
Turn the Saw over, check the underside of the Bar, and make sure that the
lubrication holes and Chain Groove are free from debris.
