SECTION 1 OPERATION
1.1 Overview
The operator seat is compatible with all ‘92 through ‘96 model LT30, LT40, LT30HD,
LT40HD, LT60HD and LT70HD standard and super mills. The seat allows the operator to
be seated while traveling with the saw head. NOTE: The seat reduces maximum cutting
length by 25". The seat can be easily removed for full-size logs.
CAUTION! Seat capacity: 300 lb (136 kg). Overloading will
damage the feed system.
WARNING! Remove seat when not using with sawmill.
Unused seat creates possible pinch point with moving saw
carriage.

10. Connect the seat to the sawmill carriage. Lift up on the seat latch, and move the seat in
toward the carriage until the latch hook is underneath the track roller housing. Release
the latch.
See Figure 1-6. Make sure the seat is securely fastened to the carriage and there is no
looseness between the seat and the sawmill carriage. Use the latch adjustment bolt to
adjust the latch. Loosen the jam nut on the latch adjustment bolt. Turn the adjustment bolt
out as desired. Check the seat for looseness. Repeat as necessary until the seat is
securely fastened to the carriage. Retighten the jam nut.
11. An adjustment handle is provided to allow the operator to slide the seat forward or back.

1.3 Towing The Sawmill With Seat
1. Move the saw head to its towing position.
2. Disconnect the seat from the sawmill carriage by pulling up on the seat latch and pulling
back on the seat. Move the seat back past the trailer wheel until the travel lock pin aligns
with the hole in sawmill frame tube. See Step 5 if your sawmill does not have a hole in the
frame tube that aligns with the seat travel lock pin.
3. Pull the travel lock pin out as far as it will go, rotate 1/2 turn, and release. The
spring-loaded pin should engage the hole in the sawmill frame tube.
See Figure 1-8.
4. Remove the step retaining pins and lift the foot step to its travel position. Replace the
retaining pins.
To unlock the seat from the traveling position, pull the travel lock pin out as far as it will
go. Rotate 1/2 turn and release into the pin resting bracket. The bracket will keep the pin
from returning to the locking pin hole.
5. Slide the seat back until the seat frame clears the sawmill fender by 2 to 3 inches.
6. Pull the travel lock pin out as far as it will go, rotate 1/2 turn, and release. Mark the loca-
tion where the travel lock pin contacts the sawmill frame tube.

7. After you have marked the location, pull the pin out, rotate the 1/2 turn, and release into
the pin resting bracket. Move the seat slightly forward to allow access to the hole location.
Start a 5/8” hole at the marked location, drilling until the point of the drill bit is just about to
break through the side of the tube. Use a hole punch to complete the hole.
CAUTION! DO NOT drill through to the inside of the tube.
Doing so will cause damage to the hydraulic lines or trailer
light wiring inside the tube.

1.4 Seat Roller ReplacementMaintenance
When replacing seat roller bearings, be careful not to overtighten the nuts that secure the
bearings to the frame.
CAUTION! Overtightening the seat roller nuts may damage
the threads on the bearing stud and/or the nut.
Maximum torque used to tighten the nuts is 65 ft.-lbs. (dry threads) or 32 ft.-lbs. (oiled
threads).
Clean and repack the roller bearings every 250 hours of operation. Remove the bearing
tires, retainer rings, and grease seals. Clean the bearings with mineral spirits. Repack the
bearing with NLGI No. 2 grade lithium grease.
