Remove fence plate and mount resaw pin to the slot
in the fence body, securing it with the knob, as
shown.

The resaw pin is usually positioned so that its center
is approximately even with front edge of blade.

See under “Operation” for further information on
using the resaw pin.

Miter gauge

Refer to Figures 34 and 35.

A miter gauge is provided for crosscutting
operations. Install miter gauge by sliding the end of
miter gauge bar into table’s T-slot.

The miter gauge should fit snugly within miter slot
while still sliding easily. The bar of the miter gauge
has two slots, each with a set screw (Figure 34).
Rotate one or both of these set screws with a 4mm
hex wrench as needed to eliminate any play
between miter gauge bar and miter slot.

If table/miter slot is square to blade

(sect. 8.10)

, the

miter gauge will also be square to blade. Before
operating, however, the 90° setting of miter gauge
should be checked in relation to the blade, as
follows.

1. Place a square against miter gauge face, and

against flat of blade, as shown in Figure 33.
(Place square against flat of blade, not the teeth
which are set wider than the blade body). A
wide blade is preferred for this procedure.

2. Flip 90° stop plate (C) out of the way, and

loosen handle (A). Shift miter gauge body until
it is flush with square, then retighten handle (A).

3. Flip stop plate (C) back down, and loosen 90°

stop hex nut and adjust screw until it contacts
the 90° stop plate.

4. Retighten hex nut.

5. Loosen set screw at base of pointer (B), and

shift pointer so that it lines up with 90° mark on
scale.

6. Retighten set screw.

The 45° stops can be checked in similar fashion,
using an angle gauge similar to that shown in Figure
37.

To adjust miter gauge angle for operations:

1. Loosen handle (A).

2. Rotate gauge body until pointer (B) lines up with

desired angle on scale. You may have to pivot
90° stop plate (C) out of the way to allow the
body to rotate.

3. Tighten handle (A).

4. There are three stops – at 90°, and 45° left and

right. Each of these can be adjusted by
loosening hex nut (D) and turning screw (E) as

needed. Retighten hex nut (D) when adjustment
is finished.

Blade speed adjustment

Refer to Figures 36 through 38.

Figure 37 shows appropriate belt position to achieve
each speed according to the particular band saw
model.

To change speed:

1. Disconnect machine from power source.

2. Loosen motor lock handle and raise motor lift

handle to release tension on belt.

3. Tighten motor lock handle to keep motor in

raised position.

4. Slide belt onto appropriate set of pulleys.

5. Loosen motor lock handle and allow motor to

lower. The weight of the motor itself should
produce proper tension for the belt. Check
tension by pushing with moderate pressure
against center of belt (Figure 38). An
adequately tensioned belt will deflect about
1/2”. If tension isn’t strong enough, push down
on the motor.

6. Tighten motor lock handle.
