Safety
Safety Instructions 2
Safety LX25 12/21/22 2-2
Wear Safety Clothing (Personal Protection Equipment)
WARNING!Always wear eye, ear, and foot protection when operating or
servicing the sawmill.
Secure all loose clothing, hair, and jewelry before operating the sawmill.
Wear gloves and eye protection when handling bandsaw blades. Chang-
ing blades is safest when done by one person. Keep all other persons
away from area when coiling, carrying, or changing a blade.
Some woods require respiration protection when operating the sawmill. It
is the sawyer’s responsibility to know which woods require respira-
tion protection.
Keep Work Area Clean
WARNING!Clean sawdust from all guards, vents, control boxes, or any
area where sawdust may gather after every shift. Failure to do so may result in fire, causing death or
serious injury
Maintain a clean and clear path for all necessary movement around the equipment and lumber stacks.
NOTICE Always properly dispose of all sawing by-products, including sawdust and wood debris, cool-
ant, oil, fuel, oil filters, and fuel filters.
If replacing a component which has a safety decal affixed to it, make sure the new component also has
the safety decal affixed.
Inspect all safety decals to ensure they are clean and readable. Replace all damaged safety decals to
prevent personal injury or damage to the equipment. Contact your local distributor, or call your Cus-
tomer Service Representative to order more decals.
Fuel/Flammable Liquid Handling Safety
DANGER!Do not smoke, weld, grind, or otherwise create sparks near your engine or storage tanks,
especially during times of fueling.
Do not allow fuel/flammable liquid to spill on a heat source, such as a hot engine.
WARNING!Store gasoline away from sawdust and other flammable materials.
Do not use flammable liquids (diesel fuel or kerosene) in the water lube accesso-
ries.
Clean fuel/flammable liquid spills immediately.
NOTICE Remove blades from equipment before cleaning them with fuel/flammable liquid.
Dispose of fuel/flammable liquids per local ordinances.

Battery Safety
WARNING!Batteries expel explosive gases; keep sparks, flames, burning cigarettes, or other ignition
sources away at all times.
Wear safety goggles and a face shield when working near batteries.
Wash hands after handling batteries to remove possible lead, acid, or other contaminants.
Charge the battery in a well ventilated area.
Do not attempt to charge a frozen battery.
NOTICE When working with batteries, do not spill or splash electrolyte (dilute sulfuric acid) as it is a
strong corrosive.
Overcharging may reduce the overall service life of the battery.
Ensure the battery is fully charged before transporting the sawmill. If the battery is not fully charged,
excessive vibration could reduce the overall service life of the battery.
Sawmill Setup Safety
WARNING!Do not set up the mill on ground with more than a 10 degree incline. Setting up the mill on
an incline could cause it to tip over.
If setup on an incline is necessary, put blocks under one side of the mill or dig out areas for the legs to
keep mill level.
Use a lifting device (fork lift, crane, etc.) for parts over 100 lbs.
Use two persons for lifting parts over 50lbs.1
Keep all non-essential personnel out of the area while setting up the sawmill.
EMERGENCY TREATMENT FOR CONTACT WITH BATTERY COMPONENTS (LEAD/SULFURIC
ACID) per SDS (Safety Data Sheet):
EYE CONTACT Sulfuric Acid and Lead: Flush eyes immediately with large amounts
of water for at least 15 minutes while lifting lids. Seek immediate med-
ical attention if eyes have been exposed directly to acid.
SKIN CONTACT Sulfuric Acid: Flush affected area(s) with large amounts of water
using deluge emergency shower, if available, shower for at least 15
minutes. Remove contaminated clothing, including shoes. If symp-
toms persist, seek medical attention. Wash contaminated clothing
before reuse. Discard contaminated shoes.
Lead: Wash immediately with soap and water.
INGESTION Sulfuric Acid: Administer large amounts of water. Do NOT induce
vomiting or aspiration into the lungs may occur and can cause perma-
nent injury or death; consult physician.
INHALATION Sulfuric Acid: Remove to fresh air immediately. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Consult a
physician.
Lead: Remove from exposure, gargle, wash nose and lips; consult
physician.

WARNING!Assemble the bed on firm, level ground. Failure to do so may cause the
sawhead to tip, causing serious injury or death.
1. Assemble all of the bed sections using track
rails and cross rails, and one cross member
where each bed section joins together.See
FIG. 3-1.
a. Attach two cross rails per bed
section. Make sure to place the
cross rails closer together, leav-
ing room for the sawhead
assembly, as shown.
b. Attach the track rails to the cross
rail. Make sure all of the cross
rails face the same direction.
NOTE: Do not attach the catch rails at this time!

2. Assemble the remaining track rails and cross rail in a similar fashion. See FIG. 3-2.
3. Connect the bed sections using a connecting plate, a clamp, and hardware.
a. Attach the connecting plate (X100-934) to each bed section, joining them together.
b. Tighten the side of the plate that has the fixed holes. Do not fully tighten the bolts (M10-1.5x30) on the side of
the plate that has slotted holes.
c. Set the clamp in place by inserting the larger notch first (on bottom) and then tilting the clamp in and upward
to catch the smaller notch (on top). See FIG. 3-3.
d. Tighten the bolts on the clamp (M10-1.5x85) to draw bed sections together.
NOTE: Be sure the track rails of each bed section are aligned before tightening the
plate bolts.

NOTE: Be sure the slotted holes on
the connecting plate are connected
to the same bed section on both
sides of the bed frame.
f. Repeat for the remaining 3 connections.
g. Attach the cross member between the bed sec-
tions.
NOTE: Optional bed extension sec-
tions may be added at this time, in
the same manner as the standard
bed sections.
4. Attach the log clamp in the middle of the bed. See FIG. 3-4.
NOTE: The log clamp is shipped with two sets of bolts and spacers. Use the
shorter bolt and the long spacer only.
5. Attach the log rest brackets and posts. Do not tighten until the bed is leveled.
3.3 Level the bed
NOTE: It is important that the bed be level for the sawhead to travel smoothly over
the rails.
1. Mount the saw bed on wooden skids for leveling and increasing the ground clearance.
A straight 4x4 or 4x6 are an ideal size for the wooden skids. If the
skids are not a solid one-piece section, make sure the seams of
skids are offset from the seams of the bed frame. See FIG. 3-5.
2. Use a 4-foot level (or laser level) to level the bed in all
dimensions. See FIG. 3-6.
3. Adjust the bed for leveling by shimming under low spots.
NOTE: Failure to square the log
rest posts can result in poor cut
quality.

4. When the bed is leveled, square up the log rest posts.
Tighten the log rest bracket screws. See FIG. 3-7.
5. Recheck saw bed for level!
3.4 Install the mast
Prepare the mast carriages
The sawhead carriages come mostly assembled from the
factory.
1. Place 4 carriage bolts from the hardware kit through
the inner side of the carriage.
2. Place washers and nuts loosely on the M10-1.5x70
carriage bolts. See FIG. 1-8.
NOTE: Do not tighten them at
this time.
3. Set the carriage on the rails.
NOTE: There is a bearing
for each side of the rail, and
the carriage rests on the
vertical bearing. The side
bearings are adjustable (slot-
ted holes), and must be
adjusted at this time. The ver-
tical bearings are not adjust-
able.See FIG. 3-9.
4. Adjust the bearings now so that the carriage glides
smoothly back and forth with little effort.
5. Repeat on the opposite side of the saw bed.
6. Remove the carriages from the rails for further installation with the mast.

Prepare mast
1. Insert the mast cross member into the upright pieces, as shown in FIG. 3-10.
2. Set the bolts in place as shown in FIG. 3-10.
NOTE: Do not tighten at this time.
Install the sawhead
1. Lay the sawhead flat on a surface high enough to
allow the carriages to extend downward (approxi-
mately 1ft (25cm)).
2. Slip the mast through the sawhead guides.
NOTE: Ensure that the
scale guide is on the
same side as the
up/down crank bracket.
3. Slide the mast uprights all the way into the car-
riages.
NOTE: Make sure that it
slides all the way to the
bottom of the carriage
and then tighten the M10-1.5x70 carriage bolts. See FIG. 3-11.
4. Install the two head-locking stop pins, locking the sawhead in the down position.
