5.  After making this adjustment, be sure to re-

check other blade adjustments as noted in this 
manual. 

7.10

  Auto shut-off adjustment 

The saw is properly adjusted when blade shuts off 
just after cut completion. To set this: 

  If saw completes cut but blade continues 

moving, adjust switch trip (P, Figure 21) 
downward. 

  If blade stops before cut is complete, adjust 

switch trip (P) upward. 

  If blade stops descending and continues 

running without completing the cut, turn stop 
bolt (Q) down. 

 

Figure 21 

7.11

  Vise adjustment 

Use handwheel (R, Figure 21) to open and close 
vise. 

Vise can be adjusted for square and miter cuts.  
Loosen hex cap bolts and adjust vise for the cut. 

Slightly loosen screw on floating vise (14mm 
wrench) to allow it to conform to tapered or irregular-
shaped pieces. Then tighten screw before 
operating. 

A scale on back side of bed aids in positioning vise 
for 90° cuts or a particular miter.

 TIP:

  Always verify 

vise position by using a square against blade and 
vise. 

7.12

  Vertical stop adjustment 

The stop screw (Figure 22) can be adjusted to 
ensure bow is at 90-degrees when using vertical 
cutting plate.

  Operation 

8.1

  Blade break-in 

New blades are very sharp and, therefore, have a 
tooth geometry which is easily damaged if a careful 
break-in procedure is not followed. Consult the 
blade manufacturer’s literature for break-in of 
specific blades on specific materials. However, the 
following procedure will be adequate for break-in of 
JET-supplied blades on lower alloy ferrous 
materials. 

1.  Clamp a round section workpiece in the vise. 

The workpiece should be 2 inches or larger in 
diameter. 

2.  Set the saw on low speed. Start the cut with a 

very light feed rate. 

3.  When the saw has completed 1/3 of the cut, 

increase feed rate slightly and allow saw to 
complete the cut. 

4.  Keep the same hydraulic cylinder setting and 

begin a second cut on the same or similar 
workpiece. 

5.  When blade has completed about 1/3 of cut, 

increase feed rate. Watch chip formation until 
cutting is at its most efficient rate and allow saw 
to complete the cut (see 

sect. 8.3, Evaluating 

cutting efficiency

).  

6.  The blade is now ready for regular service. 

8.2

  General operating procedure 

1.  Raise bow and secure in position using support, 

as shown in Figure 21. 

 

Always secure bow in 

raised position with support plate before 
loading material. Never start a cut with blade 
contacting workpiece.

 

2.  Position workpiece in vise and tighten vise. 

Workpiece should be fitted directly between 
jaws without adding other objects. When 
workpiece is profiled section, flat piece or 
special shape, refer to examples in Figure 23 
for proper clamping positions.
