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 samll or a file
held too low.
• BACKWARD SLOPE – Needs too much
feed pressure; causes excessive wear to the
bar and chain. Result 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.
• 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.
STORAGE
•
Ensure the battery is removed from the
chain saw.
•
Wipe any debris off of the chain saw,
including built up wood chips under the
chain cover.
•
Store in a dry cool place out of the reach
of children.
•
Store with the scabbard on to prevent
damage to the chain and potential damage
to other.
