CARE AND MAINTENANCE
•
Use a flat file and a depth gauge jointer to lower all
gauges uniformly. Use a 1/32 in.
• (0.6 mm) 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
Every week of use, reverse the guide bar on the saw
to distribute the wear for maximum bar life. The bar
should be cleaned every day of use and checked
for wear and damage. Feathering or burring of the
bar rails is a normal process of bar wear. Such faults
should be smoothed with a file as soon as they occur.
A bar with any of the following faults should be re-
placed:
• Wear inside the bar rails that permits the chain to
lay over sideways
• Bent guide bar
• Cracked or broken rails
• Spread rails
Lubricate guide bars weekly with a sprocket at their
tip. Using a grease syringe, lubricate weekly in the
lubricating hole. Turn the guide bar and check that
the lubrication holes and chain groove are free from
impurities.
