note of any damage and contact us immediately with any issue you may have. Note: All
equipment is assembled, tested and inspected before shipping. Damage can occur during
transit, which could cause the unit to not operate correctly.
Unpacking Unit
1 - Flat bed trailer delivery: remove straps or chains securing the unit.
2 - Remove lag screws and strapping that secures the machine to the skid.
1 - Check oil and fuel levels
2 - Check blade lubrication and
hydraulic levels (if applicable)
2-A - Check blade lubrication and
hydraulic levels.
DO NOT USE: petroleum products,
petroleum based products, flammable
products, a vegetable oil based product.
The above products mixed with water or
straight will cause damage to your mill.
The fluid will be slippery between the
blade and wheel belting causing blade to
come off.
DO USE: In The Summer Months tap
water. If there is a problem with pitch build
up on the blade, add 1 oz. of dish soap or
pinesol to 1 gallon of tap water. This will
help keep the blade clean and less heat.
In the Winter Months water will freeze
in the lube tank. Use regular windshield
washer fluid (usually blue in color) If there
is a pitch build up problem add the 1 oz. of
dish soap or pinesol.
Adjustment: Before starting the engine,
adjust the flow of lube to the blade by
adjusting the flow shut off valve so there is
a constant drip. If more lube is necessary,
continue to adjust the valve until the
desired flow is acquired.
3 - Be sure the blade is sharp and tight
4 - Be sure all levers and switches are in
the neutral/center position before starting
the engine (if applicable)
5 - Be sure all persons are clear of the
equipment
6 - Make sure the unit is level and stable.
Moving the Unit

Steps for Setting-Up the Hud-Son Saw Mill
A. Machine Set-Up (ground track unit)
a) For best results and easier set-up, the mill location should be level and free of
obstructions.
b) Alevel cement pad is the best option, but square timbers also work well. You will
need to support the track at each joint and under each cross member.
c) You will need to be sure that the mill is level from front to back and side to side.
The better the mill is supported the better the mill work.
d) There should be a 4 ft. clear work area around the entire mill.
B. Welded Track Assembly
a) Dogs needs to facing in the same direction, the moveable dogs need to be on the
same side of the track which is on the operator's side of the mill head.
b) There are additional holes in the track so that the dogs can be moved to different
positions.
c) The tracks are bolted together using bolt and nuts. The Oscar 18 and 228 mills will
have 2 bolt/nuts: the Oscar 230/236 and 52 mills will have 3 bolts/nuts. Line up the tracks
so that the center holes align. Using the provided bolts put them through the holes and
finger tighten the nuts. Adjust the track height so that the 2 pieces of track meet flush
and level. Work one side then the other, once level has been achieved, check the track to
see if it aligns vertically. If the track is not aligned correctly use a hammer to tap it into
position. Once this is accomplished tighten the bolts securely.

d) The track comes with four
track stop tabs. They consist of
the track stop tab bolt and nut.
Place the tracks stops in the four
end corners of on the inside of
the track. Place them on the
inside of the track secure them
into place with the bolt and nut.
The track stop tabs are placed at
an angle over the track to prevent
any further travel of the mill

e) To saw a board accurately, the track needs to be straight and flat. To obtain
this, use a string tied tight from end to end or a level. If the track/trailer has a crown or
dip, you will not be able to saw a straight board.

Incorrect
Dipped Track
C. Machine Set-Up (trailer unit) 20' or 24' Torsion Axle Trailers, (230, 236, 56, Farm
Boss, H360))
a) Set-up area should be relatively level and clear of debris. The head will need to roll
down the track so be sure the area is free of obstructions.
b) Lower the trailer jack and raise the jack until the coupler is free of the hitch. Once
this is done remove the unit from the vehicle. Using the "T" handles, loosen the bolts and
lower the front 2 legs.
c) Do the same to lower back 2 legs, and level the trailer.
d) Lower the center 2 legs last, the track should already be level.
e) On the 121/328 models, you will need to unbolt the head from the track. The travel bolts are located behind your guide arms at the base of the mill head.
f) Once the head is unbolted from travel position, roll it down the track to be sure it is
level. If your head rolls on its own you will need to adjust your leveling legs. Return the
head to the center of the trailer and re-bolt or raise the center legs to lock head into place.
Once the head is secure you can reset the leveling legs.
**Always secure the head before re-leveling the trailer***
g) Once the trailer is level, the head should not roll on its own. If your trailer is not level,
it will not saw your boards correctly. Refer to previous instructions for proper set-up.

D. Setting Head on Track (If Applicable) Ground Models
Once your track is level, you are ready to set the head on the track. Once again, be
sure the area is still free and clear of obstructions. You will want the head to roll
freely down the track.
a) Install the head with operator's side on the same side as the moveable dog. The
discharge side is the side with the squaring pins.
b) Raise the head 3 inches and roll from one end to the other. The head should roll

smoothly along the track. If the head "thumps" when it passes over the track joint, check
to make sure the tracks are level. Re-level the track and try rolling the head again. Also
be sure to watch the track as you roll the head, if the track moves, you will need to support the track in that area.
c) Set the guide bracket so that the back bearing is on the same plane as the blade, so
that if the blade were to wander back it would hit the back bearing evenly across the middle of the roller. If the bearing needs to be adjusted up or down, loosen the bolt that holds
it to the guide bracket and space it in either direction using the washers that are on either
side of the bearing.
d) Once the bearing is set, position the guide bracket so that the bearing is spaced 1/8"
behind the back of the blade. Once the bearing is in position, tighten the bolt on the top
of the guide bracket into place. Be sure guide is 90
o
to the blade.
e) The guide shoes are to be set using a sheet of paper to gauge the spacing. Place the
paper between the shoe and the blade, slide the shoe so that it is pinching the paper, and
tighten the bolt so that the shoe is set in place. Do the same on the bottom of the blade.
Note that you do not want the shoes to be pinching the blade so hard that they are prohibiting blade travel.
f) Make sure that all nuts and bolts are tightened firmly.

Set-Up and Operation
E. Tensioning the Blade on all Models
NEVER tension your blade with the engine running. Your mill is shipped to you without any tension on the blade. If there is tension left on the blade for a period of time,
it can cause flat spots in the belt.
Page 10
10
This will cause the blade to fall off the wheel. Always remember to de-tension your
blade when you are done sawing for the day.
a) a) To tension or loosen the blade, see figure below.
b) Turn the adjusting bolt or stud, clockwise until 30-35 pounds of torque is achieved.
The recommended tool for this is a torque wrench. By hand, rotate blade 3-4 full revolutions; this centers the blade on the wheels.
c) With gloves on, pull up on the blade at the center guard. Allow for no more than a
¼" movement up or down on the blade.
d) Blade guides must not be so tight they cause the blade to heat up. If this occurs readjust guides.
e) Perform a simple test call the "Flutter" test. Put the guards on and then run the
engine at full RPM's (be sure the blade is not in a cut during this test) and watch the blade
under the blade guard. The blade must run straight, if it does not, shut the engine down
and apply more tension. Keep in mind that over tensioning will also cause the blade to
flutter. You should have attained proper tension around 30-35 pounds.
f) A tensioned blade should come off the bottom of the band wheel and run straight
across to the other band wheel, so there is NO sag in the blade between the two wheels.

(121/328)
F Setting Logs
Once the track is set, the head is in place and the blade is tensioned correctly, you are
almost ready to cut.
a) Place the log determined by the mills size, on the center of the track. Using the log
dogs secure the log to the track. Be sure to dog the log high enough (1/2" way up the log)
to ensure the log does not move. If the log is too big for the log dog to hold in place, but
your sawmill head still rolls unobstructed use the "Cheater" to hold it. (For use on the
121/328 only).

G. Getting Ready to Cut
Now is the time to debark or clean your log. This can be achieved by the simple chainsaw attachment, called a Log Debarker (available through Hud-Son Forest Equipment
Inc.) or you can pressure wash or use whatever method available to remove any mud
or bark from the logs. By debarking and cleaning your log it will extend the life of your
blade.
a) Adjust the Hud-Son guides so that they are slightly (no more than 2 inches) wider than
the maximum width of the log.
(Note: as you cut slabs, boards or squares you may need to adjust the guide to ensure
the best performance and quality cuts)
b) Find the top of the log with the blade. Remember, that you may have cheaters in
place so be sure these are clear when making the first cut. You will be removing the top
potion of the log. (top slab)
c) On the manual lift models, crank your head down to the desired height and click up
one notch to set the head. Make sure your blade will clear your dog assembly.
d) Start your engine, let it idle for at least 5 minutes. (Refer to the engine manual for
proper engine maintenance)
e) With the engine in idle position, increase the throttle to start the blade. Sawing
should always be done with the engine in full throttle.
f) Gently push the saw head through the log, pushing on the head frame. If the engine
starts to labor, you are going to fast, slow down. Go slow through burls and knots as the
engine may bog down through these parts of a log.
g) When you are at the end of the log, power down the engine, crank the head up so
that will clear the log and roll back to the front of the log. For ease of operation, put the
slabs on the operator's side of the mill, this way you will not have to dig through sawdust
for your lumber.
h) You now have a flat surface on top of your log, remove the cheaters (if applicable),
you will no longer need them, as long as the log dogs will hold the log in place.
i) Set your log dog assembly so that they are standing in the track. Turn the cut side
of the log, using a cant hook, ¼ of a turn. The flat side must be flush against the squaring
pin to assure a square cant.
j) Adjust the log dog at an angle to the track so that the blade can pass over the top,
but so that the dogs are effective in securing the log.
Debark the log.

k) Once again, increase the engine throttle to start the blade, and saw another slab.
You will repeat step (I) until your log is squared into a cant. You may now saw your
dimensional lumber.
l) Steps (I-K) may not be applicable if a cant is not desired.
Adjustable dog, set at an angle so that log can be
sawed without interference.
Place flat side, flush against squaring pin to
ensure a square cant.
H. Cutting Dimensional Lumber
You can cut down to a 1" thick bottom board. To achieve this you will use the moveable side of the dog and the short squaring pins welded in the track.
a) You will need to determine the size lumber that can be cut and how many, then using
the scale start sawing your lumber. Lower the blade to desired thickness and saw your
board. Repeat this process unit all lumber is cut.
b) You may need to turn your cant to make the desired lumber.
I. Replacing the Blade
No matter how well you care for your blade, they will dull after time and need to be
changed. Longevity of your blade depends on how well you maintain it.
a) The engine needs to be stopped, turned off and the key removed, this ensures that
the engine can not be accidentally turned back on. On engines with manual start, you will
need to remove the spark plug wire prior to servicing. On electric motors a lockout/tagout
should be used.
b) Loosen and remove wing nuts so you can remove the outside and center guards on
all models.
c) Loosen band blade tensioner bolt until adjusting bolt is flush with threaded plate.
d) With a gloved hand, put hand on the top of the band blade and push down. (Use
extreme CAUTION, dull blades are still sharp and may be hot).
e) Remove band blade from both band wheels and take out of carriage.
f) Inspect new or sharpened blade, be sure blade teeth are facing in correct direction.
Teeth should always point away from the operator. (Towards discharge chute). Be sure
to wipe blade clean of all oily substance prior to installing. Aclean, dry rag or cloth works
best.
g) Starting from your stationary wheel set the blade on the wheel then thread though
your guides. Work the blade over the tensioning wheel until the blade is set.
h) Lightly tension the blade to remove the slack, and then turn the wheel in the direction of travel (towards the operator) 3-4 rotations to be sure the blade is tracking properly on the wheel.
12
Page 13

i) Once the new blade is tracking properly, replace the guards and re-tension the blade
as previously stated.
J. End of Processing Lumber
a) Completely decrease engine throttle and turn engine switch, red one, to off position.
b) The blade will continue to turn automatically and will coast to a stop.
c) If you are done sawing for the day, de-tension the blade, so that you do not have flat
spots. Lower the mill head so that the lift cable has slack.
K. Blade Maintenance
Longevity of band blades depends on how well they are cared for. Using a lube tank,
Log Debarker, band blade sharpener, tooth setter, all will help keep your blade in top
condition. Be sure to clean your logs by using a pressure washer or debarker to keep
them free of mud and debris. Refer to 2A on page 6
L. Blade suggestions
a) Never force a dull blade, this will result in overheating of the blade and result in
wavy lumber.
b) Overuse of a blade jeopardizes the ability of the saw blade to be re-sharpened.
c) A new blade may stretch after cutting and may have to be re-tensioned to assure
quality lumber.
d) De-tension the band blade after each day of cutting.
e) Never operate the mill without the guards in place.
The Hud-Son Forest Equipment, Inc sawmill comes with a band blade and we have an
excellent re-sharpening program for your band blade.
M. Adjusting Sawmill Guides
a) Purpose of the Guides
• Superior Hud-Son guide design. Supports on the top, bottom and back of the
blade, where can the blade go? This guide design limits the chance of blade wander.
• The lower blade holds the blade up and decreases the chance of "diving". Most
companies only use a top support.
• The closer to the log the guides are to the log the better support the blade has
as it cuts.
b) Adjusting the guides
• Tools that will be needed:
1) 17 mm wrench
2) 17 mm socket
3) 9/16" wrench
4) 3/16" Allen wrench
Page 14
14
• All guides are aligned and set at the factory, but occasionally they get moved
out of adjustment in shipping or after a period of usage. It is important that they be
checked often for proper alignment and adjusted correctly.
• To adjust your guides correctly you must first tension the blade properly as previously described. A tensioned blade should come off the bottom of the band wheel and
run straight across to the other, so there is NO sag between the two wheels.
c) Now that the blade is tight, slightly loosen the Allen head that holds the guide shoes,
so that they slide up and down freely. Now loosen the bolt that fastens the aluminum
guide bracket to the guide rod, so that the guide bracket can be moved in, out and it can
be rotated in either direction.
d) Set the guide bracket so that the back bearing is on the same plane as the blade, so
that if the blade were to wander back it would hit the back bearing evenly across the middle of the roller. If the bearing needs to be adjusted up or down, loosen the bolt that holds
it to the guide bracket and space it in either direction using the washers that are on either
side of the bearings.
e) Once the bearing is set, position the guide bracket so that the bearing is 1/8" behind
the back of the blade. Once the bearing is in position, tighten the bolt on top of the guide
bracket in to place. Be sure the guide is 90 to the blade.
f.) The guide shoes are to be set using a sheet of paper to gauge the spacing. Place the
paper between the shoe and the blade, slide the shoe so that it is pitching the paper and
tighten the bolt so that the shoe is set in place. Do the same on the bottom of the blade.
Note that you do not want the shoe to be pitching the blade so hard that it is prohibiting
blade travel
g) Make sure that all nuts and bolts are tightened firmly.
N. Using the Lumber Scale
a) All Hud-Son sawmills are equipped with a Lumber Scale. The scale is used to make
the dimensioning process simple. The scale incorporates 4 separate scales with the blade
kerf factored in for each increment.
Scale Resulting Thickness
4/4 1”
5/4 1 - 1/4”
6/4 1 - 1/2”
8/4 2”
Note:
The 1" standard ruler does NOT account for kerf. When using this scale be sure to
plan on kerf. 1" increments will result in approximately a 7/8" end result, depending
on what blade is being used.
