SECTION 1 SURGE BRAKE HITCH
1.1 Operation
IMPORTANT! Your vehicle should be equipped with a
Class hitch with a solid 2 5/16” ball (not two-piece) and
rated for at least 6000 pounds (2722 kg). The hitch should
be correctly mounted to the towing vehicle so that it will be
able to pull this type of load.
1. Pull the mill behind the towing vehicle and place the hitch over the ball coupling on your
vehicle. 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.
See Figure 1-1.
2. Flip the locking handle upward, being sure the bracket underneath firmly clamps around
the ball. Secure the locking handle with the safety pin.
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. Fail-
ure to do so may result in serious personal injury and/or
severe machine damage.
3. 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.
4. Connect the surge brake activator cable to the vehicle. This cable should be connected in
case the hitch becomes unhooked and the safety chains fail. The surge brake activator
cable would then activate the braking mechanism. There should be enough slack in the
brake cable that the brake won't engage until the safety chains are stretched tight.
5. Connect the light wiring harness plug from the sawmill to the recetacle on your vehicle.
Check signals and brake lights.
6. Raise the front outrigger. Recheck that all loose items are removed or secured (such as
Resaw Option, Shingle/Lapsiding Option, cant hooks, etc.).
7. The hitch on the mill is adjustable. It should be raised or lowered to let the mill travel hori-
zontal to ground level. Adjust by removing the two mounting bolts. Then slide the hitch
tube up or down to new set of holes. Replace bolts and nuts.
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 brake and 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.
DANGER! Chock the mill to prevent movement before
unhitching it from the towing vehicle. Failure to do so may
result in serious injury or death.

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.

Maintenance

1.2 Maintenance
1. Clean and repack the trailer axle wheel bearings with lithium grease every 12 months or
12,000 miles (19,308 km), whichever comes first.
2. Make sure that the trailer tires are correctly inflated to the pressure shown on the tire.
CAUTION! Always check trailer tires for proper inflation
before towing sawmill. Failure to do so may result in
machine damage.
3. Check the adjustment of the trailer hitch coupler bracket frequently and adjust if neces-
sary. Replace any bent or otherwise damaged parts before using the hitch. Use only parts
provided by the hitch manufacturer for this hitch model.
4. The trailer brakes should be adjusted as follows:
after the first 200 miles of operation when the brake shoes and drums have
“seated,”
at 3,000 mile intervals,
or as use and performance requires.
The brakes should be adjusted in the following manner:
1. Jack up the trailer and secure on adequate capacity jack stands. Follow the trailer manu-
facturer's recommendations for lifting and supporting the unit. Make sure the wheel and
drum rotates freely.
CAUTION! Do not lift or support trailer on any part of the
axle or the suspension system. Never crawl under your
trailer unless it is resting on properly placed jack stands.
2. Remove the adjusting hole cover from the adjusting slot on the bottom of the brake back-
ing plate.
3. With a screwdriver or standard adjusting tool, rotate the star wheel of the adjuster assem-
bly to expand the brake shoes. Adjust the brake shoes out until the pressure of the linings
against the drum makes the wheel very difficult to turn. NOTE: For drop spindle axles, a
modified adjusting tool may be necessary.
4. Rotate the star wheel in the opposite direction until the wheel turns freely with a slight lin-
ing drag.

Maintenance
SB70-R03doc091317 -2
5. Replace the adjusting hole cover and lower the wheel to the ground.
6. Repeat the above procedure on all brakes. For best results, the brakes should all be set
at the same clearance.
The wheel nut torque should be 90lbs.-ft. Tighten in 3 stages.
See Table 1-1. The wheel torque requirements are shown below.
Tighten bolts or nuts in the sequence shown for Wheel Torque Requirements.
See Figure 1-2.

If applicable, grease the Fine Adjust Outriggers (FAOs) every 200 hours of operation or
once a month, whichever comes first. Use one squeeze of a NLGI No. 2 grade lithium
grease from a grease gun to lubricate the outrigger and remove any sawdust.
See Figure 1-3.
Pre-2008 Style Fine Adjust Outriggers (Optional)
If applicable, grease the Fine Adjust Outriggers (FAOs) every 200 hours of operation or
once a month, whichever comes first. Use one squeeze of a NLGI No. 2 grade lithium
grease from a grease gun to lubricate the outrigger and remove any sawdust.
See Figure 1-4. To access the outrigger grease fitting, raise the outrigger base all the
way. The grease fitting will be accessible through the lowest outrigger hole.
