TOP PLATE FILING ANGLE
Q CORRECT 30° – file holders are marked with guide
marks to align file properly to produce correct top
plate angle.
Q LESS THAN 30° – for cross cutting.
Q MORE THAN 30° – feathered edge dulls quickly.
SIDE PLATE ANGLE
Q CORRECT 80 o – Produced automatically if you use the
correct diameter file in the file holder.
Q HOOK – “Grabs” and dulls quickly, increases the
potential of KICK-BACK.
Results from using a file with a diameter too small or a
file held too low.
Q 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.
MAINTAINING DEPTH GAUGE CLEARANCE
Q Maintain the depth gauge at a clearance of 0.6 mm
(0.025 in). Use a depth gauge tool for checking the depth
gauge clearances.
Q Every time the chain is filed, check the depth
gauge clearance.

Q Use a flat file (not provided) and a depth gauge jointer
(not provided) to lower all gauges uniformly. Use a 0.6
mm (0.025 in.) 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.
See Figures 65 and 66.
Q 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.
