Blade Tension

Use the knob (Figure 15) to tension the blade.

Clockwise tightens the blade, counterclockwise

loosens it.

Blade Tracking

Tracking the blade requires

that the band saw be operating while the

back blade cover is removed. Use extreme

caution and keep hands away from blade.

The blade provided with your band saw has

already been tracked at the factory and requires

no adjustment.

When the blade is replaced, tracking may be

required for the new blade. It is recommended

that tracking be done by a person experienced

in these procedures and aware of the dangers

involved.

1. Turn the socket set screw (Figure 15) as

needed to shift the angle of the idler wheel.

NOTE: This adjustment is sensitive; do it

gradually and in small increments allowing

the wheel to respond to the changes.

2. Tracking is set properly when the back of

the blade lightly touches the wheel shoulder.

NOTE: Over-tracking (allowing blade back

to rub hard against wheel shoulder) will

damage the blade wheels and blade.

Setting Blade Speed

1. Disconnect band saw from power source.

2. Open the pulley cover.

3. Loosen the knob (see A, Figure 3) and lift

up on the motor. Move the belt to the

desired pulley grooves. A chart is affixed to

the inside of the belt guard showing the

positions for the three speeds, 80, 120 and

200 surface feet per minute (SFPM). This

chart is also shown in Figure 16.

4. Push the motor back down to tension the

belt, and tighten the knob (A, Figure 3).

Material chips or shavings are the best indicator

of proper blade speed and downfeed rate. The

ideal chip is thin, tightly curled and warm to the

touch. Chips that range from golden brown to

black indicate excessive force. Blue chips

indicate extreme heat from too high a blade

speed, which will shorten blade life. Thin or

powdered chips indicate insufficient downfeed

rate.
