MAINTAINING DEPTH GAUGE
CLEARANCE
See Figure 55 - 57.
 Maintain the depth gauge at a clearance of .025
in. Use a depth gauge tool for checking the
depth gauge clearances.
 Every time the chain is filed, check the depth
gauge clearance.
 Use a flat file and a depth gauge jointer to lower
all gauges uniformly. Use a .025 in. depth gauge
jointer. After lowering each depth gauge, restore
original shape by rounding the front. Be careful
not to damage adjoining drive links with the
edge of the file.
 Depth gauges must be adjusted with the flat file in
the same direction the adjoining cutter was filed
with the round file. Use care not to contact cutter
face with flat file when adjusting depth gauges.

MAINTAINING THE GUIDE BAR

See Figure 58.
CAUTION:
Make sure the chain has stopped 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 sprocket at the end of the guide
bar using a grease gun in the sprocket lubrica-
tion 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
