MAINTAINING THE GUIDE BAR
See Figure 45.
CAUTION:
Make sure the chain has stopped and the bat-
tery pack has been removed before you do any
work on the saw.
Proper maintenance will maximize the useful life
of the guide bar.
Each day of use:
Clean the bar and check for wear and damage.
Feathering or burring of the bar rails is a normal
process of bar wear, but such faults should be
smoothed with a file as soon as they occur.
Each week of use:
 Reverse the guide bar on the saw to distribute
the wear.
 Lubricate the socket at the end of the guide bar
using a grease syringe in the lubricating hole.
 Turn the guide bar and check that the lubrication
holes and chain groove are free from impurities.
A bar with any of the following faults should be
replaced immediately:
 Wear inside the bar rails that permits the chain
to lay over sideways
 Bent guide bar
 Cracked or broken rails
 Spread rails
Chain specifications: 3/8 in. pitch, low profile narrow kerf, .043 in. chain gauge, 5-tooth drive sprocket.
Length of Bar
