MAINTENANCE
SIDE PLATE ANGLE
•
Maintain the depth gauge at a clearance of 1/32 in. (0.6 mm). 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
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 replaced:
• 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.
