SECTION 1 INSTALLATION PROCEDURE
1.1 Pre-Installation Procedure
1. Remove the drive pulley/belt cover from the sawmill.
2. If applicable, disconnect the encoder cable from the existing Setworks control and
remove the encoder and mounting bracket from the sawmill.
3. Pre-2006 sawmills only: 1 Note the blade height indicator position on the inch scale and
remove the scale pointer assembly from the mill. Set the mounting hardware aside.
Remove the existing blade height scale assembly from the mill. Remove the scales from
the scale mounting bracket, then set the scales and mounting hardware aside.
NOTE: Sawmills manufactured after 11/00 have four
threaded holes in the mast. If your sawmill has the threaded
holes, skip to Sensor Installation (See Section 1.2). If your
sawmill does not have the threaded holes, continue with
this procedure.
4. Position the supplied template on the sawmill vertical mast tube 4 5/16” from the top of
the tube.
1 Sawmills prior to LT30 Rev. J8.01, LT40 Rev. J9.01, LT30 Super Rev. J3.07, LT40 Super Rev. J4.08, LT30HD Rev. J9.01,
LT40HD Rev. K1.01, LT30HD Super Rev. J8.08 and LT40HD Super Rev. J8.09. The scale mount and pointer assembly
will be replaced on these sawmills. Newer mills do not require replacement of the scale mount and pointer assembly.

See Figure 1-1.
5. Mark the locations indicated by the holes in the template on the mast tube.
NOTE: Accurate location is necessary for proper mechani-
cal and sensor operation.
6. Relocate the template 44 9/16” from the top of the mast tube and mark the two hole loca-
tions.
7. Use the #3 (7/32”) drill bit provided to drill holes through one wall of the mast tube at all
four locations.
8. Thread all four holes with the 1/4-20 tap provided.

1.2 Sensor Installation (Rev. A.01+)
NOTE: The sensor mounting brackets were redesigned in
April 2001. See Section 1.3 if your mounting brackets do
not look like the ones shown below.
1. Install the magnet to the bracket with the provided #8-32 x 7/8” hex head bolts, flat wash-
ers and nylon lock nuts. Slide the magnet assembly onto the sensor (the assembly will be
secured later).
See Figure 1-2.

3. Install two of the provided 1/4” lock washers and 1/4-20 x 5/8” hex head bolts to the bot-
tom set of threaded holes in the mast. Thread the bolts about halfway into the holes. Slide
the slotted lower mounting bracket of the sensor assembly around the two bolts, behind
the lock washers. Slide the upper mounting bracket up or down as necessary so the
bracket holes align with the holes in the mast. Secure with the remaining two lock wash-
ers and hex head bolts. Tighten all four mounting bolts. Use large channel lock pliers on
the transducer nut to turn the asssembly so the label is viewable.
See Figure 1-4.

4. Pre-2006 sawmills only: Remove the blade height and quarter scales from the removed
scale mount bracket. Use the existing hardware to secure the scales to the provided
scale mount bracket.
See Figure 1-5.
Assemble the new scale mount bracket to the sawmill mast and secure the at the top with
the existing hardware. Leave the bottom loose until after the magnet assembly is
installed.

5. Install the sensor magnet mount block to the scale mount bracket using the four provided
#10-24 x 1/2" hex head bolts and flat washers. Check the area between the bracket and
block. If there is a gap, use the provided extra #10 washers as necessary to fill the gap.
This will prevent bending of the scale bracket when the mounting bolts are tightened.
6. Position the magnet assembly so the holes in the magnet mounting bracket align with the
holes in the magnet mount block.
7. Secure the magnet assembly to the mount block with the provided 1/4-20 x 3/4” hex head
bolts and flat washers. Adjust the assembly in the slotted holes so the magnet is centered
around the sensor rod.
See Figure 1-6.

8. Pre-2006 sawmills only: Use the two provided #10-24 x 3/8" pan head screws and
self-locking hex nuts to secure the provided scale pointer to the new pointer mount plate.
Then, use existing hardware to secure the pointer mount plate to the sawmill.
See Figure 1-7.
Secure the bottom of the blade height scale assembly with the existing hardware. Leave
the nuts loose enough you can still move the scale assembly up or down. Adjust the
assembly until the blade height indicator shows the measurement noted before the old
scale assembly was removed. Tighten the mounting nuts.
Apply the appropriate decals supplied to the pointer mount plate.
9. Connect the transducer cable to the socket at the bottom of the sensor.

1.3 Sensor Installation (Rev. A.00)
NOTE: The sensor mounting brackets were redesigned in
April 2001. See Section 1.2 if your mounting brackets do
not look like the ones shown below.
1. Install the lower mount clamp (with large hole) flush with the threaded portion at the base
of the sensor. Use two of the provided 1/4-20 x 3/4” flat socket head bolts to secure a
mounting block to the clamp. Note the orientation of the sensor, mount clamp and mount-
ing block. The clamp and block should be oriented as shown to ensure proper assembly
to the sawmill. The sensor should be oriented so the specification label faces away from
sawmill bed. Use one of the provided 1/4-20 x 1” socket head bolts to secure the clamp to
the sensor.
See Figure 1-9.
