Loosen the adjusting screws and move the brush up to the wheel.

None.

The wheel bearings are sealed and lubricated for life.

The belts could be damaged.

The center sheave of the variable speed pulley is lubricated by a wick

which is immersed in oil.

To replace a wheel tire on the model 2612-1M bandsaw machine, remove

the two retainers from the front of the band wheel. Then remove the tire

retaining rings.

Drive the tire off the wheel, sawing off the steel

backing, if necessary.

Mount a new tire so that the two notches in the

steel backing are in alignment with the two tire retainers.

Put the new

tire on with light taps of a soft-faced hammer, rotating the wheel about 30

degrees as each tap is made, until the tire is against the flange of the

wheel.

Powdered graphite is used very sparingly to lubricate the air pump.

The bracket, when properly adjusted, will just clear the motor plate

when it is at its highest position during operation.

Second Requirement

When saw band vibration occurs during sawing operations on the model

1612-0 bandsaw machine, these checks should be made:

(1) Check the band speed.

Saw band vibration can be caused by the

selection of the incorrect band speed.

(2) If the band speed is correct, the pitch of the saw blade may be

incorrect.

Check the pitch of the saw blade, and select a blade of the

proper pitch, if required.

(3) If a blade with the proper pitch is in use, but severe saw band

vibration is still present, the
