SECTION 1 SAFETY & GENERAL
INFORMATION
This symbol calls your attention to instructions
concerning your personal safety. Be sure to
observe and follow these instructions. This
symbol accompanies a signal word. The word
DANGER refers to hazards that can cause
death or serious, irreversible personal injury.
The word WARNING suggests a safety hazard
that can cause personal injury. CAUTION
refers to hazards that can cause damage to the
equipment or property only.
Read all safety instructions before operating
this equipment and observe all safety warnings!
DANGER! Make sure hitch bracket is securely
fastened around ball before towing the sawmill.
Ball should be completely engaged by the hitch
bracket and securely locked in place.
DANGER! 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 railer equally in the event the hitch became
disengaged.
DANGER! Be sure that the hitch and safety
chains are secure before towing the sawmill.
Check all lights and signals for correct opera-
tion. Check to see tires are properly inflated and
surge brakes are working before towing the
sawmill.
WARNING! Always check trailer tires for
proper inflation before towing sawmill.
CAUTION! Always keep away from tailer axle
to avoid being caught between the axle and
moving saw carriage.
IMPORTANT! It is always the owner’s respon-
sibility 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 thor-
oughly familiar with these applicable laws and
comply with them fully while using or towing
the mill.f

Surge Brake Hitch Operation

SECTION 2 SURGE BRAKE
HITCH OPERATION
1. Pull the mill behind the towing vehicle and
place the hitch over a 2" ball on your vehicle.
The hitch ball should be solid (not two-piece)
with a rating of 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.
2. Flip the locking handle upward, being sure the
bracket underneath firmly clamps around the
ball.
DANGER! Make sure hitch bracket is securely
fastened around ball before towing the sawmill.
Ball should be completely engaged by the hitch
bracket and securely locked in place.
See Figure 2-1.
3. Cross the safety chains underneath the hitch and
hook to the vehicle. The chains should be con-
nected so that there is still slack in the chains
when the vehicle is turned sharply in either
direction.
DANGER! 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.
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 vehicle running lights to the saw-
mill pigtail. 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 horizontal
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.
Check all lights and signals for correct opera-
tion. Check to see tires are properly inflated and
surge brakes are working before towing the
sawmill.

SECTION 3 SURGE BRAKE
HITCH
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.
WARNING! Always check trailer tires for
proper inflation before towing sawmill.
3. Surge Brakes
Check the brakes before towing the sawmill.
Jack up the outriggers so that the trailer wheels
do not touch the ground. Spin each wheel by
hand. The wheel should spin with a slight
amount of drag against the brake drums. If the
wheel spins freely, the brakes should be
adjusted.
See Figure 3-1. To adjust the brakes, remove
the oval shaped plug from the access hole on the
inside of each wheel.
Place a standard screwdriver through the access
hole and underneath the adjustment sprocket.
Catch the bottom of the sprocket with the
screwdriver and pry upward to turn the
sprocket. Remove the screwdriver and spin the
wheel. Adjust the sprocket until the wheel just
starts to drag against the brake drum. Replace
the plug. Repeat for the other wheel.
