2. Raise the motor to relieve the belt tension and position the belt into the desired pulley alignment.
3. Release the motor and let ts weight tension the belt.
4. Tighten the motor lock bolt back against the frame of the band saw.

HEAD LOCK PIN
The head locking pin (Fig. Q - 1) safely secures the head in the down position. To ensure the head does not unex-
pectedly spring up and tip the bandsaw over, this locking pin must be properly inserted when the band saw is not
in use or before moving it.
To use the head locking pin, fully lower the head down. Insert the locking pin through the holes in the head pivot
arm and base, locking the head into the down position (Fig. Q).
