Maintaining The Guide Bar - Ryobi RY43155 Manual Del Operador

 Use a flat file and a depth gauge jointer to lower
all gauges uniformly. Use a .025 in. depth gauge
tool. 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 46.
WARNING:
Make sure the chain has stopped and the tool
is unplugged from the power supply before you
do any work on the saw to avoid accidental
starting or contact with the moving chain that
may result in 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.
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.
MAINTENANCE
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
