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:
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.
