Chapter 4: Maintaining Your NEUTON Corded 16” Chain Saw
This chapter explains how to adjust the Chain Tension, sharpen the Chain and Guide Bar Maintenance.
Always remove the power cord before performing any adjustments, maintenance, or repairs to your Chain 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
Guide 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 5
). 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 (
Figure 5
).
NOTE:
A new Chain tends to stretch so check the Chain tension frequently and re-
tension as required.
1. Loosen the Chain Tensioner Lock (
Figure 6
) by turning it counterclockwise
just enough so that you can move the outer Chain Tensioner Knob.
2. Turn the Chain Tensioner Knob (
Figure 6
) clockwise to tension the Chain as
required and then retighten the Chain Tensioner Lock.
Chain Sharpening
For smooth and fast cutting, you need to maintain the Chain properly. The Chain
requires sharpening when the wood chips are small and powdery, if you must
force the Chain through the wood during cutting, or the Chain cuts to one side.
NOTE:
Improper Chain sharpening increases the risk of Kickback. Therefore, we
highly recommend that when the Chain requires sharpening, you have the
Chain professionally sharpened.
Guide Bar Maintenance
When the Guide 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 Guide Bar
•
Cracked or broken Rails
•
Spread Rails
Turn the Saw over, check the underside of the Guide Bar, and make sure that the
lubrication holes and Chain Groove are free from impurities.
