7.9 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 7-9)
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.

7.10 Vise adjustment
Use handwheel (R, Figure 7-9) to open and close
vise.
Vise can be adjusted for square and miter cuts.
Loosen hex bolts on fixed jaw (T) and adjust to
desired angle. Refer to scale on back of bed for
angle. (For precise work, always verify with a square
against blade and vise.) tighten bolts.
Slightly loosen bolt on floating jaw (S) to allow it to
conform to workpiece as jaw is brought into
clamping position. Tighten bolt before operating.
7.11 Vertical stop adjustment
The stop screw (Figure 7-10) can be adjusted to
ensure bow is at 90-degrees when using vertical
cutting plate. Loosen nut, adjust screw, then tighten
nut against casting to secure setting.

8.0 Operation
The HVBS-56V is equipped with a motor driver
containing a voltage feedback device to provide
consistent torque during operation.
The saw is also provided with an overload protection
device to prevent overheating of the motor. If saw
shuts off because of overload, allow to cool a few
minutes, then restart.
8.1 Blade selection
The saw is provided with a blade that is adequate
for a variety of cut-off jobs on a variety of common
materials.
See Table 3 for recommended speeds for various
materials. These selections, while appropriate for
many shop cutting needs, do not encompass the
wide variety of blades of special configuration (tooth
pitch and set) and special alloys for cutting unusual
or exotic materials.

Table 3: Speed recommendations
A coarse blade could be used for a solid steel bar
but a finer tooth blade would be used on a thin-wall
tube. In general, the blade choice is determined by
the thickness of the material; the thinner the
material, the finer the tooth pitch.
