caps

Install additional caps (Video-53:30)

track base

Putting the Track Together (Video-53:43)

*If you are using the standard steel track you will need a support base. In the instructional video, we are using 6” x 6” timbers. Timbers or lag bolts are not included with your sawmill*

Start by setting your track support base up, making sure it is square.

measure track base

Support base should measure 21 3/4” wide.

layout the track

Place all of the steel side rails on your support base.

Rails are labeled. Make sure end cross members have the 3/8 hole pointing down and wider holes facing out.

add cross members

Place middle cross members according to the bolt holes.

chalk line

Use a chalk line to ensure rails are lined up and a 1/2” from the outside edge of your base.

square up

Line side rails up to chalk line and square up side rails with end cross member.

make sure its level

Make sure you are working on a level surface. Shim side rails if necessary.

screw in

There are three 3/8 holes in the side rails (they should be facing down). The 3/8 holes are for lagging the track to your support base. There will be a 3/8” hole on the side. This is use for the attaching the log dogs. Make sure middle cross members are flush and square to the side rails before securing to the base.

measure the track

Double check the rails are 20 3/4” apart.

add cant stops

Place crossmembers 24” apart between siderails making sure cant stops are on the discharge side of the track. “Cant stops are the yellow tabs that bolt the crossmembers to the side rails.”

Once the track is laid out on the 6” x 6” support base, make sure everything is square. Once the track is square, mount the track to the 6” x 6” support base using lag bolts. *Lag bolts are not included.*

install end stops

Install all four end stops. This keeps the mill from running off the end of the track. (PKG 15)

add log dogs

Installing Log Dog Assembly (Video-1:01:24)

Backstop should be on the same side as the cantstops (B side of the mill; the dog will be on the A side of the mill.)

Remove axle. Place log dog in track and slide axle through track, log dog and through the track on the other side.Tighten set bolt.

put mill on track

Put the mill on the track (Video-1:02:17)

Off Deck Setting (Video-1:02:34)

Tighten blade. Thread off-deck bolts into frame to achieve a 1”off-deck setting on each side of the machine. Make sure blade is tight.

measure 1"

Measure from the bottom of the blade to the top of the cross member.

*This should measure 1” on each side. If this measurement is off, the off deck setting bolts can be

adjusted to achieve the 1”*

run the mill

Raise the head and start sawmill again to ensure it runs properly down the track.

ALWAYS LOOSEN YOUR BLADE WHEN YOU’RE DONE USING IT.

CORRECTIONS FOR IMPROPER ASSEMBLY OF MEASUREMENTS

1. CAGE MEASUREMENTS

– Use the extra washer in the cage assembly hardware kit to correct any offset measurement.

– If needed, the shim washers will be installed in the inside of the center cross beam.

– Recheck that the measurement is equal on top and bottom of the lift tubes, tension bolt.

– Hardware fits together so there is a small space instead of the wrong way which is a bigger space.

– Use a level to check in see if the mill head is vertically aligned correctly. If it is not, you may have to install shims between the bearing and the mill head. The manufacturing process during welding may cause differences to the inner head frame red shims.

2. TRACK WHEEL ALIGNMENT

-If it does not measure 20 3/4 apart, adjust number of alignment washers accordingly to achieve this

measurement.
