turning bolt (At Fig. 18).
6. Connect the machineto the power source.
Adjusting Automatic Shutoff
The saw should stop after the cut has been
completed:
1. If the saw completes the cut and continuesto
run, adjust the stop tip (A, Fig. 19)down.
2. If the saw shuts off before the cut is complete,
adjust the stop tip (A, Fig. 19) up.
3. If the saw stops cutting but continues to run,
adjust the stop bolt (B, Fig. 19).
The saw is properly adjusted when the saw shuts off
just after the blade has finished the cut.
Lubrication
Ball bearings on the blade guide assembliesand the
bladewheels are permanently sealed and require no

Maintenance
1. Keep all surfaces clean and free of rust, slag,
chips, and coolant build-up.
2. Do not use compressed air to clean the
bandsaw. Compressed air may force chips into
the guide bearings and other critical areasof the
saw.
3; Use a small paint brush or parts cleaning brush
to remove metal particles.
4. Wipe the saw downwith a clean, dry cloth and
oil all unpainted surfaces with light machineoil.
5. Keep the blade guides clean and free of metal
chips.
6. Checkthe guide bearings frequently to make
sure they are properly adjusted and turning
freely.
Chip Cleaning Brush
It is very important that the blade cleaning brush be
properly adjusted and kept in good working order.
Replace the brush if it becomes damaged or worn
out. Blade life will be shortened severely if the brush
is allowed to go out of adjustment, becomes
damaged, or is worn out.
