SECTION 1 LOAD ASSIST KIT INSTALLATION
The Load Assist Kit option is intended to assist a single person to load and unload the LT15 on and off a trailer. The option may
be assembled to any LT15 model sawmill with two bed sections. If the LT15 is equipped with a third bed section, it must be
removed before using the load assist option.
The customer should provide a tilt-style trailer with a single-post tongue. The size of the trailer should be at least 5’ wide by 10’
long with a load rating of at least 1,000 lbs. Be sure to factor in any other items to be hauled (such as a third bed section) when
choosing the trailer size and capacity.
IMPORTANT! It is always the owner's responsibility to comply with all applicable federal, state and local laws,
rules and regulations regarding the ownership, operation and towing of your Wood-Mizer sawmill. All
Wood-Mizer mill owners are encouraged to become thoroughly familiar with these applicable laws and comply
with them fully while using or towing the mill.
Follow all trailer and winch manufacturer’s operating and safety instructions.
1.1 Winch
1. Follow the manufacturer’s instructions provided with the winch to install the winch strap and handle to the winch.
2. Install the winch assembly to the winch stand with the provided three 3/8-16 x 1” hex head bolts, flat washers and lock nuts.
3. Position the winch stand on the trailer tongue post with the stand
base approximately 12” from the trailer. Orient the stand so it
angles away from the trailer. Secure the winch stand to the post
with the winch mount plate and four 3/8-16 x 4 1/2” hex head bolts,
flat washers and lock nuts See Fig. 1-1.
4. Install the winch hook plate to the hole in the motor mount plate on
the sawmill. If your sawmill was manufactured before 3/08, you will
need to drill a 13/32” diameter hole in the motor mount plate at the
dimensions shown. Secure the winch hook plate to the hole using
the provided 5/16-18 x 1” hex head bolt and lock nut. See Fig. 1-2.
1.2 Wheel Assemblies
1. Disassemble the feed rope from the mount bracket at the front of the sawmill bed.
2. Disassemble the feed rope bracket and hardware from the bed.
3. Install the left wheel mount assembly to the bed tube, aligning the holes with the holes in the bed.
4. At the location where the feed rope mounts, insert one of the provided 1/2-13 x 3 1/2” hex head bolts to the hole in the bed
cross brace.

5. Replace the feed rope bracket and hardware. Install the provided 1/2” lock washer and jam nut to the bolt.
6. Continue the bolt through the wheel mount and secure with a flat washer and lock nut.
NOTE: Feed rope bracket hardware will vary depending on bed revision. Beds rev. F.00 and newer use one flat washer
& a spacer bushing. Prior revision beds use two flat washers.
7. At the other cross brace hole, insert a 1/2-13 x 3 1/2” hex head bolt and wheel mount. Secure with a flat washer and lock
nut.
8. After the wheel mount is installed, tighten the jam nut to secure the feed rope bracket against the bed cross brace and rein-
stall the feed rope to the bracket. See Fig. 1-3.
9. Install the right wheel mount assembly to the other side of the bed using two 1/2-13 x 3 1/2” hex head bolts, flat washers
and lock nuts. See Fig. 1-4.

SECTION 2 LOAD ASSIST KIT OPERATION
2.1 Loading
DANGER! Keep all persons out of the path of moving equipment when loading or unloading sawmill. Follow all safety
precautions provided in the winch manufacturer’s instructions. Failure to do so will result in serious injury.
1. Move the saw head to the rear of the sawmill.
2. Lower the head all the way down to the bed.
3. Insert a cant hook, or similar prying tool into the tube on the left-side wheel assembly. Push up to lift the wheel until the
spring-loaded locking pin secures the wheel in place.
4. Repeat for the right-side wheel assembly.
5. Adjust the next-to-last outriggers up or remove them from the bed.
6. Adjust the clamp posts all the way up.
7. Position the trailer at the front of the sawmill. Be sure the vehicle and trailer are aligned and centered with the sawmill. Turn
the winch handle to orient the handle toward the sawmill.
8. Carefully back the trailer under the lift assist wheels. Continue back until the front sawmill bed cross brace is about 1” from
the winch handle.
9. Insert the cant hook into the tube on the right-side wheel assembly. Lift to relieve pressure on the locking pin. Pull the lock-
ing pin and lower the cant hook until the sawmill is resting on the trailer.
10. Repeat for the left-side wheel assembly. Remove the retaining pin and disassemble the wheel/arm assembly from the
wheel mount.

11. Place the winch ratchet pawl in the neutral position and pull the winch strap toward the saw head and hook onto the bracket
on the motor mount plate.
WARNING! Keep clear of spinning winch handle. Failure to do so could cause personal injury.
12. Lower the clamp posts.
13. Raise the saw head just enough to clear
any objects, such as trailer fenders, that
may interfere with the saw head as it
moves toward the front of the sawmill.
14. Engage the ratchet pawl and turn the
winch handle to pull the saw head toward
the front of the sawmill.
15. Stop when the front locking pin is aligned
with the hole in the bed frame.
16. Leave the winch strap hooked to the saw
head to help secure it during transport.
17. Rotate the front locking pin to the travel
position so the pin engages the hole in
the bed frame.
18. Leave the rear locking pin in the opera-
tion position to prevent the saw head
from tipping.
NOTE: See your LT15 operator’s
manual for detailed locking pin oper-
ating instructions.
19. Lower the saw head all the way down to
the bed. If applicable, remove the water
lube tank and mounting bracket from the
saw head.
20. Strap the sawmill securely to the trailer (straps not included). Use at least two straps, one to secure the bed and one to
secure the saw head.
2.2 Unloading
DANGER! Keep all persons out of the path of moving equipment when loading or unloading sawmill. Follow all safety
precautions provided in the winch manufacturer’s instructions. Failure to do so will result in serious injury.
1. Remove straps holding sawmill to the trailer.
2. Raise the saw head just enough to clear any
objects, such as trailer fenders, that may interfere
with the saw head as it moves toward the rear of the
sawmill.
3. Place the front locking pin in the operation position.
The rear locking pin should already be in the operation
position. See your LT15 operator’s manual for detailed
locking pin operating instructions.
4. Make sure the winch strap is still hooked to the
bracket on the motor mount plate.
5. Place the winch ratchet pawl in reverse.
6. Let out enough of the winch strap so you can move
the saw head just to the tilting point of the trailer.
7. Place the winch ratchet pawl in forward.

9. Grasp the winch handle securely and move the ratchet pawl to reverse.
10. Turn the winch handle to allow the saw head to move back and tilt the trailer down to the ground.
11. Continue turning the handle until the saw head reaches the rear of the sawmill.
12. With the rear end of the sawmill resting on the ground and the saw head all the way at the rear of the sawmill, lower the saw
head all the way down to the bed.
13. Adjust the next-to-last outriggers up or remove them from the bed.
14. Adjust the clamp posts all the way up.
15. Unhook the winch strap from the bracket on the motor mount plate and wind the strap onto the winch.
