Adjusting Automatic Shutoff
The saw should stop afterthe cut has been
completed:
1. If the saw completes the cut and continuesto
run, adjust the stop tip (A, Fig. 19) down.
2. Ifthe saw shuts off before the cut is complete,
adjust the stop tip (A, Fig. 19) up.
3. Ifthe saw stops cutting but continuesto run,
adjust the stop bolt (B, Fig. 19).
The saw is properlyadjusted when thesaw shuts off
just after the blade has finished the cut.

Lubrication
Ball bearings on the blade guide assembliesand the
bladewheels are permanentlysealed and require no
lubrication.
Lightly lubricate the vise screw with #2 tube grease.
Change gear box oil after the first 90 days of
operation. There after, changeevery six months
To change gear box oil:
1. Disconnect the machine from the power
source.
2. Place the saw arm in the horizontalposition.
3. Remove screws (A, Fig. 20) from the gear box
and remove the cover plateand gasket.
4. Hold a container under the lower right corner of
the gear box with one handwhile slowly raising
the saw arm with the other.

5. Placethe saw arm in the horizontalposition
again. Wipe out remaining oil witha rag.
6. Fillthe gear box with approximately3/4 pint of
90 weight gear oil.
7. Replace the gasket and cover. Fastenthe cover
with screws.
8. Connect machinetTthe power~ource.
Maintenance
1. Keep all surfaces cleanand free of rust, slag,
chips, and coolant build-up.
2. Do not use compressed air to clean the
bandsaw. Compressedair mayforce chips into
the guide bearings and other critical areas of the
saw.
3; Use a small paint brush or parts cleaning brush
to remove metal particles.
4. Wipe the saw downwith a clean, drycloth and
oil all unpainted surfaces with light machineoil.
5. Keepthe blade guides clean and free of metal
chips.
6. Checkthe guide bearingsfrequently to make
sure they are properly adjusted and turning
freely.
Chip Cleaning Brush
It is very important that the bladecleaning 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 ifthe brush
is allowed to go out of adjustment, becomes
damaged, or is worn out.
