9-9.BLADE AND COOLING SYSTEM

 

 

 

The use of proper cutting fluid is essential to obtain 

maximum efficiency from a band saw blade. The main cause 

of tooth failure is excessive heat build-up. This is the reason 

that cutting fluid is necessary for long blade life and high 

cutting rates. cutting area and blade wheels should be kept 

clean at all time. 

 

A          Fig.12       

The rate of coolant flow is controlled by the stop valve lever 

(A) (fig 12), which directs the coolant onto the blade. 

The lever (A) is shown in the off position. 

 

9-10.OPERATING AND ADJUSTING VISE 

 

The work-piece is placed between the vise jaws with the 

amount to be cut-off extending out past the blade. Your 

machine is equipped with a "quick action" Vise jaw which 

allows you to instantly position the moveable vise jaw B 

(fig, 14).                                                                                       

 

                                                                                                   

Fig.13

   

 

Simply turn hand-wheel A

 

counterclockwise 1/2 turn and move the vise 

jaw s to the desired   

 

 

 

position. Then tighten the vise jaw B against the   

work-piece by turning hand-wheel clockwise.
