MAINTENANCE Parts Of A Cutter Top Plate Rivet Hole Cutting Corner Side Plate Depth Gauge Heel Gullet Toe Left hand Cutters Right hand Cutters • 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. WARNING: The saw chain is very sharp. Always wear protective gloves when performing maintenance to the chain to prevent serious personal injury. CAUTION: Make sure the battery is removed from the chainsaw before you work on the saw. CAUTION: A dull or improperly sharpened chain can cause excessive motor speed during cutting, which may result in severe motor damage. TOP PLATE FILING ANGLE • CORRECT 30° - file holders are marked with guide marks to align file properly to produce correct top plate angle. • LESS THAN 30° - for cross cutting. • MORE THAN 30° - feathered edge dulls quickly. SIDE PLATE ANGLE • Correct 80° - Produced automatically if you use the correct diameter file in the file holder. • Hook - "Grabs" and dulls quickly; increases the potential of kickback. Results from using a file with a diameter too small or a file held too low. • Backward Slope - Needs too much feed pressure; causes excessive wear to the bar and chain. Results from using a file with a diameter too large or file held too high. 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. Depth Gauge Jointer Flat file Restore Original shape by Rounding the front 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. Lubricating hole 20
