BELT AND PULLEY ARRANGEMENTS FOR ALL EIGHT AVAILABLE SPEEDS
Fig. 32 | Fig. 33 |
With the longest belt on the inside groove of the motor pulley (B) Fig. 32 and on the drive pulley (C), and the small belt in one of the remaining three grooves of the motor pulley and the corresponding groove of the gear box pulley (E), speeds of 40, 60, 85, and 3000 SFM are readily available. To obtain speeds of 40, 60, and 85 SFM, push the shifter knob (F) Fig. 32 all the way in, and position the small belt on one of the three outside grooves of the motor pulley (B) and the gear box pulley (E).
Blade speeds of 115,160, 220, 335, and 3000 SFM are available by simply interchanging the positions of the motor pulley and the gear box pulley. Fig. 33 shows the motor pulley (A) positioned on the gear box shaft and the gear box pulley (B) positioned on the motor shaft. With the long belt positioned on the inside groove of the pulley (B) and the pulley (C), and the small belt positioned in one of the remaining three grooves of the pulleys (A) and (B) Fig. 33, speeds of 160, 220, and 335 SFM are obtained when the shifter knob (D) is pushed in.
To obtain a blade speed of 115 SFM, push in the shifter knob (D), remove the long belt from the pulleys (B) and (C), and place the small belt on the inside groove of the motor pulley (B) and the inside groove of the gear box pulley (A).
Except for the one speed of 115 SFM, both belts may be left on the machine, regardless of the blade speed.
