Chain Maintenance - Snapper SC60V Manual De Instrucciones

NOTE: During normal saw operation, the
temperature of the chain increases. The drive
links of a correctly tensioned warm chain will
hang approximately 1/16 in. (1,58 mm) out of
the bar groove.
NOTE: New chains tend to stretch; check
the chain tension frequently and tension as
required.
1/16 in. (1,58 mm)
CAUTION:
A chain tensioned while warm may be
too tight upon cooling. Check the "cold
tension" before next use. Never tension
a warm chain before storing as chains
shrink when cool. This can damage the
chain, bar and saw.

CHAIN MAINTENANCE

Use only a low-kickback chain on this saw.
This fast-cutting chain provides kickback
reduction when properly maintained. For
smooth and fast cutting, maintain the chain
properly. The chain requires sharpening
when the wood chips are small and powdery,
the chain must be forced through the wood
during cutting, or the chain cuts to one side.
During maintenance of the chain, consider the
following:
• Improper filling angle of the side plate can
increase the risk of severe kickback.
• Raker (depth gauge) clearance:
- Too low– increases the potential for
kickback.
- Not low enough– decreases cutting ability.
• If the cutter teeth hit hard objects such as
nails or stones, or are abraded by mud or
sand on the wood, have an authorized service
center sharpen the chain.
NOTE:
• Inspect the drive sprocket for wear or
damage when replacing the chain. Have the
drive sprocket replaced by an authorized
service center if there are any signs of wear
or damage.
• If you do not fully understand the correct
procedure for sharpening the chain after
reading the instructions that follow, have
the saw chain sharpened by an authorized
service center or replace with a recommended
low-kickback chain.
MAINTENANCE
SHARPENING THE CUTTERS
Be careful to file all cutters to specified angles
and to the same length, as fast cutting can be
obtained only when all cuters are uniform.
Make sure the battery is removed from the
chain saw before you work on the saw.
The saw chain is very sharp. Always
wear protective gloves when performing
maintenance to the chain to prevent serious
personal injury.
• Tension the chain prior to sharpening.
Refer to Adjusting The Chain Tension.
• Be careful to file all cutters to the specified
angles and to the same length, as fast
cutting can be obtained only when all
cutters are uniform.
• Tension the chain prior to sharpening.
Refer to Adjusting The Chain Tension.
• Use a 5/32 in. (4 mm) diameter round
file and holder. Do all of your filing at the
midpoint of the bar.
• Keep the file level with a top plate of the
tooth. Do not let the file dip or rock.
• Using light but firm pressure. Stroke
towards the front corner of the tooth.
• Lift the file away from the steel on each
return stroke.
• Put a few firm strokes on every tooth. File
all left hand cutters in one direction. Then
move to the other side and file the right
hand cutters in the opposite direction.
• Remove filings from the file with a wire
brush.
CAUTION:
A dull or improperly sharpened chain can
cause excessive motor speed during cutting,
which may result in severe motor damage.
Improper chain sharpening increases the
potential of kickback.
Failure to replace or repair a damaged chain
can cause serious injury.
