CHANGING SPEED SE'I-FING(FIG.Y)

12 Replace the blade wheel. Push the wheel on firmly until it is touching the saw pulley. Replace and tighten the flange and nut.

BLADE WHEEL TIRES

Pitch and sawdust that build up on the tires should be removed with a stiff brush or scrape off with a piece of wood.

To avoid injury, turn the switch OFF and disconnect the saw from the power source before making any adjustments. NEVER make adjustments with the machine running.

1.Loosen the belt tension by turning the tension lock handle (6).

2.Open the lower wheel cover and reposition the V-belt (3).

A.Changing the speed from 1410 to 2600 FPM: Remove the belt (3) from the band saw pulley (4) first, and reposition in the saw pulley groove (1). Next, remove the belt from the motor pulley (5) and reposition in the motor pulley groove (1).

B.Changing the speed from 2600 to 1410 FPM: Remove the belt (3) from the motor pulley (5) first, and reposition in the motor pulley groove (2). Remove the belt from the saw pulley (4) and reposition in the saw pulley groove (2).

3.Tighten the belt tension by turning the tension lock handle (6).

NOTE: After readjusting belt position and belt tension, check and readjust the settings for the blade tension and tracking, guides and bearings (See ADJUSTMENT section).

To avoid possible injury or damage, NEVER use this band saw to cut ferrous metals.

CAUTION: When cutting nonferrous metals, metal shavings can react with wood dust and start a fire. To avoid this:

1.Disconnect any dust collecting hose from the band

SaW.

2.Remove all traces of wood dust from inside the saw.

3.Remove all metal shavings from inside the saw before sawing wood again.

GENERAL MAINTENANCE

. For your own safety, turn switch OFF and remove the plug from power source receptacle before maintaining, cleaning, adjusting, or lubricating your band saw.

,To avoid fire or toxic reaction, never use gasoline,

naphtha, acetone, lacquer thinner or similar highly volatile solvents to clean the band saw.

,To avoid eye injury from blowing debris, wear safety goggles when blowing out sawdust.

BAND SAW

Sawdust will accumulate under the table and base. This could cause difficulty in the movement of the table when setting up a band saw cut, and also cause a fire hazard. Frequently blow out or vacuum up the sawdust.

Keep your band saw clean. Remove the sawdust from the inside. Vacuum or blow out frequently.

Do not allow filth to build up on the table, the guides, or the

support bearings. Clean them with Craftsman Gum and Pitch Remover.

NOTE: Do not immerse the support bearings in the gum and pitch remover.

Put a thin coat of paste wax on the table so that the wood slides easily while cutting.

TO INSTALL A NEW BELT (FIG. Z)

1.Open the lower wheel door.

2.Loosen the blade tension by turning the blade tension lock knob (!).

3.Remove the blade from the lower blade wheel

4.Loosen and remove the hex head bolt (2) and flange (3) on the lower blade wheel.

5.Remove the lower blade wheel.

6.Turn the belt tension handle (4) on the rear of the saw housing to loosen the v-belt tension.

7.Remove the v-belt (5).

8.Check the alignment of the two pulleys.

9.If the edges of the two pulleys are not aligned, see "ALIGN THE PULLEYS" in ADJUSTMENT section.

!0. Place the new v-belt on the saw puiley and the motor pulley. See OPERATION section "CHANGING SPEED SETTINGS" on page for proper belt placement.

11.When positioned properly, tighten the v-belt tension by turning the tension lock handle.

NOTE: The pulley belt is properly tensioned when there is 1/2" deflection if pressed in the center between the pulleys.

13.Reinstall the blade (See iNSTALLING BLADES Section on page ).

14.Adjust the blade tension, tracking, and the upper and lower blade guides and bearings before operating the band saw.

To avoid injury, the blade tension, tracking, and upper and tower guides and bearings musl be properly adjusted before operating the band saw. (See ADJUSTMENT INSTRUCTIONS section)

FIG. Z

NOTE: To avoid damaging the tires do not use a sharp knife or any kind of solvent.

When the tires become worn they should be replaced. When replacing the tires, stretch them around the wheels but do not glue them on.

MOTOR

Frequently blow or vacuum out any sawdust from the motor. Follow lubrication instruction on the motor label.

To avoid electrocution or fire immediately replace a worn, cut

or damaged power cord.'

LUBRICATION

All of the bearings ar# packed with grease at ti'_e.factory. They require no further IL_brication.

CAUTION: Never put.lubric.ar_tson the blade while it is spinning.
