SECTION 1 TRAILER INSTALLATION
IMPORTANT! The trailer option is intended for use with LT15 sawmills Rev. E4.00
(LT15BS bed section Rev. E.00) and newer with three bed sections. LT15 sawmills prior
to Rev. E6.08 require modification to the mast to allow repositioning of the up/down sys-
tem (See Section 1.3).
1.1 Pre-Assembled Sawmill
If you are adding the LT15TRG trailer option to an assembled LT15 sawmill, the assem-
bled sawmill bed can be lifted onto the trailer frame. Be sure to use adequate manpower
and lifting equipment to safely lift and stabilize the sawmill during installation.
1. Disassemble the feed rope from the rear rope bracket and remove from the feed crank
pulley. Remove the rear feed rope bracket from the sawmill. Move the saw head to the
rear end of the bed and support with lifting equipment such as a forklift or hoist. Remove
the saw head from the bed and set aside.
2. Using adequate lifting equipment, lift the sawmill bed off the ground. Remove the legs.
See Figure 1-1.
3. Position the trailer next to the sawmill, oriented so the front of the sawmill is at the hitch

SECTION 2 TRAILER OPERATION
2.1 Preparing The Sawmill For Travel
IMPORTANT! Your vehicle should be equipped with a
Class 2 hitch with a solid 2” ball (not two-piece) and rated
for at least 3500 pounds (1588 kg). The hitch should be
correctly mounted to the towing vehicle so that it will be
able to pull this type of load.
1. Move the saw head to the front of the sawmill and raise the rear outriggers.
2. Disconnect the water hose (and fuel hose if equipped) and remove the water tank (and
fuel tank if equipped) from the saw head mast.
3. Replace the fenders in the brackets behind each wheel and secure with the locking
straps.
4. Move the saw carriage to the travel position and secure the travel lock pins as described
in the LT15 operator’s manual. Pivot the saw head rest bracket up and lower the saw
head until the pin engages the bracket and secure with the retaining pin.
CAUTION! Secure the saw head in the travel position
before towing the sawmill. Failure to do so may result in
damage to the machine.
5. Place log loading ramps on sawmill bed. Raise winch to upright position and route cable
around loading ramps. Tighten cable to secure loading ramps to bed.
6. Raise all but the very front outrigger.
7. Pull the mill behind the towing vehicle and place the hitch over the ball coupling on your
vehicle. Adjust the front outrigger to lower the trailer until the hitch engages the ball.
Adjust the coupler if necessary so it is as tight as possible on the ball and the locking
lever can still be opened and closed.
8. Flip the locking handle downward, being sure the bracket underneath firmly clamps
around the ball. Secure the locking handle with the safety pin.

Trailer Operation

2-2 1510doc111714 Trailer Operation
DANGER! Make sure hitch bracket is securely fastened
around ball before towing the sawmill. Ball should be com-
pletely engaged by the hitch bracket and securely locked in
place. Use the hitch only with the specified ball size. Failure
to do so may result in serious personal injury and/or severe
machine damage.
9. Cross the safety chains underneath the hitch and hook to the vehicle. The chains should
be connected so that there is still slack in the chains when the vehicle is turned sharply in
either direction.
DANGER! Make sure your hitch has adequate safety chain
hookups. Do not use eyebolts for safety chain hook-up.
Safety chains should be hooked to bumper of vehicle so
that each chain would pull the trailer equally in the event the
hitch became disengaged. Failure to do so may result in
serious personal injury and/or severe machine damage.
See Figure 2-1.
10. Connect the trailer light harness to the towing vehicle light plug.
11. Raise the front outrigger all the way up and place the outrigger jack handle in the storage
bracket at the rear of the sawmill.
12. Recheck that all loose items are removed or secured (such as Shingle/Lapsiding Option,
cant hooks, etc.).

13. Make sure all connections are secure and trailer lights are working properly.
DANGER! Be sure that the hitch and safety chains are
secure before towing the sawmill. Failure to do so may
result in serious personal injury and/or severe machine
damage.
DANGER! Make sure all light connections have been made
and are working properly before towing the sawmill. Failure
to do so may result in serious personal injury and/or severe
machine damage. Make sure you have complied with all
applicable Federal, State and Local motor vehicle safety
laws.
14. Check tires for proper inflation.
WARNING! Always check trailer tires for proper inflation
before towing sawmill. Failure to do so may lead to tire fail-
ure resulting in property damage and/or serious injury or
death.

2.2 Preparing The Sawmill For Operation
WARNING! Do not set up the mill on ground with more than
a 10 degree incline. If setup on an incline is necessary, put
blocks under one side of the mill or dig out areas for outrig-
ger legs to keep mill level. Setting up the mill on an incline
could cause it to tip over, resulting in serious personal
injury.
WARNING! Chock the trailer wheels to prevent movement
before unhitching it from the towing vehicle. Failure to do so
may result in serious injury or death.
WARNING! Always make sure the trailer is supporting the
sawmill frame when operating a sawmill with adjustable
outriggers. Failure to do so may result in serious injury or
death. The adjustable outriggers are intended to support
the saw frame with assistance from the trailer.
WARNING! The adjustable outriggers supplied with porta-
ble sawmills are not intended for setup on concrete or other
hard surfaces. Long-term use of the adjustable outriggers
on hard surfaces may cause the outriggers to fail, causing
the sawmill to drop. This could result in possible serious
injury or death.
If setting the sawmill up on concrete or other hard surface,
replace the adjustable outrgger legs with stationary legs.
WARNING! Put front outrigger down before moving cutting
head from the rest position. Failure to do so may result in
serious injury.
1. Position the sawmill in an area that is suitable for sawing.
2. Chock the trailer wheels to prevent movement while unhitching the trailer.
3. Unhook the safety chains and light harness from the vehicle and unhitch the sawmill.
Lower the front outrigger and set on the ground.
4. Release the winch cable and remove the log loading ramps from the sawmill.
5. Remove the saw head retaining pin and raise the saw head from the rest bracket. Pivot
the rest bracket down.

6. Move the saw carriage to the front of the sawmill and lower the remaining outriggers.
Remove the jack handle from the storage position and use to adjust the outriggers to lift
weight from the trailer axle and level the sawmill. Use the jack handle to lift the weight
from the locking pin. If necessary, rotate the locking pin counterclockwise so that the inner
roll pin is free from the outrigger channel notch, then pull the locking pin out to release the
outrigger. Lower the outrigger as necessary. Push the locking pin back in and turn clock-
wise until the inner roll pin is behind the outrigger channel notch to “lock” the outrigger in
place.
