considered worn out or excessively ―stretched‖ if the chain cannot be
tensioned sufficiently to prevent the drive links from coming completely out of
the groove. Discard the chain.
5.3.5. Check the segment wear. The segment is considered worn-out when the
height is worn down to about 1/16‖, or when the segment width is the same
as the chain chassis.
5.3.6. After each use clean the slurry and debris off the chain; then apply a light
coating of oil to prevent rusting.
5.4. POWERHEAD MAINTENANCE
5.4.1. After using saw inspect all hardware and tighten fasteners as needed.
5.4.2. Inspect the Felt Washer (#71) to ensure it is integral, replace if damaged.
5.4.3. Maintain the Tensioner Assembly by removing the Guide Bar Wear Plate
(#24). Clean the slot, Tensioner Carriage (#53), and Tensioner Screw (#60).
Apply new grease to the entire assembly and replace the Wear Plate (#24) as
shown in Section 8.1.
5.4.4. Remove Spool Cover (#12) and lubricate Spool Linkage (#9) and associated
pivot points.
5.4.5. Inspect, clean, and lubricate Bar Studs (#23).
5.4.6. Inspect Bumper Pad (#58) and replace when it becomes worn.
6. FACTORS AFFECTING CHAIN LIFE
Optimum performance from your chain saw will depend largely on selecting the proper
chain for the application. If the cutting medium is too soft for the chain rating used, you
may get fast chain wear. If the cutting medium is too hard for the chain rating used, you
will get segment glazing and/or very poor cutting performance. This chapter is a guide in
making the proper chain selection.

6.1. HOW DIAMOND SEGMENTS WORK
Cutting concrete, stone, and other hard, brittle materials is a grinding or abrading action.
Cutting segments are composed of hard, abrasion resistant diamond particles
distributed randomly in a metal matrix. The diamonds abrade or scratch out particles of
