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 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.
