the extendable shaft, bar, and chain.

Unpacking and Assembly
• Tighten the side cover knob
• Saw chain tension is correct when, with some
effort, a gloved hand can pull the chain
smoothly around the bar The chain should
touch the underside of the bar rail (Fig 14)
FIG. 14
After a short period of use, allow the chain to
cool and once again check the tension (remove
the battery first) Watch tension carefully
for the first half-hour of use and periodically
throughout the life of the chain, readjusting as
required when the chain and bar are cool to the
touch Never tighten chain when it is hot
Chain will stretch as a result of normal use,
but insufficient oil, aggressive use, or failure to
perform recommended maintenance can lead
to premature stretching
