OTHER CONTROLS

Saw blade tension lever (at rear of driven wheel)
Quick approach function
III-12
Used to keep the saw
blade tensioned to a
constant degree by a
hydraulic cylinder.
Turned to the "
position to tension the saw
blade and to the "
position to slacken the saw
blade.
Used to rapidly lower the
sawhead to bring the saw
blade close to the work and
shorten the idle time.
When the sawhead lowers
and the quick approach
feeler touches the work,
the sawhead automatically
changes to the downfeed
speed. During automatic
operation, the quick
approach feeler detects the
height of the work and
prevents the useless rise of
the sawhead.
If the quick approach function is not required, pull up the feeler and push
it to the stroke end. The feeler is locked in that position. When the
feeler is locked, the sawhead always lowers at the downfeed speed.
To unlock the feeler, securely hold the feeler with one hand, and push
the release lever for the HFA-250 and HFA-250W and pull the release
lever for the HFA-400 and HFA-400W. The feeler will be unlocked and
drop under its own mass.
CAUTION
NOTE
The machine cannot be automatically operated when the feeler is locked.
