50-hour Maintenance
Every 50 hours of operation (more frequently in dusty or dirty
conditions):
■
Using a lever-type grease gun, pump lithium-base grease (about 10 grams)
into the grease fitting (D) until you see old grease being purged from
the gearcase, which can be seen in the outer tube cavity. Clean up excess
grease, then reassemble the gearcase onto the outer tube.
Sharpening the Chain
■
When the cutting edges of the blade become dull, they can be re-sharpened
with a few strokes of a file.
■
In order to keep the blade in balance, all cutting edges must be sharpened
equally.
■
In addition, inspect the chain for correct adjustment (more frequently with a
new chain). The chain should feel snug but still pull freely. Refer to adjustment
procedures.
CAUTION!
Keep the chain sharp and properly adjusted.
WARNING!
The saw chain is very sharp. Wear gloves to protect your hands when work-
ing with or around the saw chain.
