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

end of the trailer. Lower the trailer outriggers and use the jack handle to adjust the outrig-

gers to lift the trailer weight off the wheels and to level the trailer frame.

4. Disengage the trailer fender locking straps and lift the fenders from the trailer.

5. Lift the trailer winch assembly and pivot the winch down to the ground.

6. Pivot the saw head rest bracket down.

7. Position the sawmill onto the trailer frame, aligning the leg mounting holes with the holes

in the trailer frame. Secure the sawmill bed to the trailer frame with the provided mounting

bolts, bushings, washers and nuts.

See Figure 1-2.

8. Reassemble the saw head to the sawmill and replace the rear feed rope bracket. Leave

the feed rope disassembled until trailer installation is complete.

1.2 Unassembled Sawmill

If you are adding the LT15TRG trailer option to a new unassembled LT15 sawmill, the

sawmill bed can be assembled to the trailer frame. Be sure to use adequate manpower

and lifting equipment to safely lift and stabilize the sawmill during installation.

1. Lower the trailer outriggers and use the jack handle to adjust the outriggers to lift the

trailer weight off the wheels and to level the trailer frame.

2. Disengage the trailer fender locking straps and lift the fenders from the trailer.

3. Lift the trailer winch assembly and pivot the winch down to the ground.

4. Pivot the saw head rest bracket down.

5. Position the sawmill bed sections onto the trailer frame with the track position on the left

side of the trailer as viewed from the hitch end. Connect the bed sections as described in

the LT15 manual. Align the leg mounting holes with the holes in the trailer frame and

secure the bed to the trailer frame with the provided mounting bolts, bushings, washers

and nuts.

See Figure 1-3.

6. Refer to the LT15 manual to complete sawmill assembly and setup (skip the feed rope

installation until trailer installation is complete).

Up/Down & Feed Handle Relocation

1-4 1510doc111714 Trailer Installation

1.3 Up/Down & Feed Handle Relocation

Because the sawmill sits higher when mounted to the optional trailer, parts are included

that allow you to relocate the up/down and feed crank handles to a lower position.

1. Move the saw head to rear of the sawmill and lower all the way down. Lower the saw

head until it rests on the bed to provide slack in the up/down chain.

2. Loosen the up/down chain lower sprocket mounting bolt and the chain tension bolt.

3. Disassemble the up/down chain master links from the mounting bracket and remove the

chain from the sawmill.

See Figure 1-4.

the locations specified. Tap the holes with 3/8-16 threads. Note: LT15 Rev. E6.08 include

a block with threaded hole welded at the upper location. LT15 Rev. E6.09 and newer

7. Use a C-clamp or vise to press the provided bearings into the up/down mounting bracket

housing. Be sure the bearings are oriented with the seals facing outward. To avoid dam-

aging the bearings, do not use a hammer to install.

8. Install the mounting bracket to the sawmill mast positioned two holes lower than the origi-

nal bracket. Use the existing hardware to secure the top of the bracket to the mast.

9. Install the new chain mount bracket at the bottom of the mast using the existing hardware

to secure.

See Figure 1-7.

10. Disassemble the up/down crank assembly:

See Figure 1-8. Standard crank assembly: Use a 5/32” punch to remove the roll pin

securing the crank assembly to the sprocket/shaft weldment. Remove the crank assem-

bly and sprocket/shaft weldment from the mount bracket. Remove the two bolts, washers

and lock nuts to disassemble the dial from the mount bracket.

See Figure 1-9. Gear-reducer crank assembly: Disassemble the four bolts holding the

guard, dial and crank assembly to the mounting plate. Use a 5/32” hex wrench to remove

the two button head socket screws holding the sprockets to the hub. Use a 5/32” punch to

remove the roll pin securing the hub to the sprocket/shaft weldment. Remove the hub and

sprocket/shaft weldment from the mount bracket. Remove the two bolts and washers to

disassemble the mounting plate from the mount bracket.
