Maintaining The Guide Bar - Ryobi RY40509 Manual Del Operador

DEPTH GAUGE JOINTER
DEPTH GAUGE CLEARANCE
See Figures 36 - 37.
 The depth gauge should be maintained 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. Depth gauge jointers are
available in .020 in. to .035 in. 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 38.
CAUTION:
Remove the battery pack from the chainsaw and
make sure the chain has stopped before you do
any work on the saw. Failure to do so may result
in accidental starting and possible serious injury.
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.
