MAINTENANCE
MAINTAINING DEPTH GAUGE CLEARANCE
• Maintain the depth gauge at a clearance of .025" (.6 mm). Use a depth gauge tool for checking
the depth gauge clearances.
• Every time the chain is led, check the depth gauge clearance.
• Use a at le and a depth gauge jointer to lower all gauges uniformly. Use a .025" (.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 le.
• Depth gauges must be adjusted with the at le in the same direction the adjoining cutter was
led with the round le. Use care not to contact cutter face with at le when adjusting depth
gauges.
MAINTAINING THE GUIDE BAR (See Fig. 36)
CAUTION
Make sure the chain has stopped before you do any work on the saw.
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
le 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 of impurities.
