SECTION 1 REMOTE OPERATION
The Remote Option provides remote operation for all sawmill functions from a single
location at the front of the sawmill. The option includes all cables with traveling guide
chain, a remote electrical power junction box, a front-mounted sawmill control box, and a
remote clutch mechanism with switch to engage the blade from the remote location.
The Remote Option also includes Wood-Mizer’s Simple Setworks system which allows
automatic, incremental up/down movement of the cutting head.

1.1 Preparing for Remote Operation
Set up the sawmill as instructed in your sawmill operator’s manual.
CAUTION! Moving the saw carriage before removing the
cable chain support may cause damage to the chain. Also,
moving the saw carriage when the chain is frozen can
damage the chain. See Section 1.4 for recommended chain
deicing procedure.
See Figure 1-1. Before moving the saw carriage, remove the cable chain support
bracket.
1. Disengage the rubber strap holding the cable chain to the support bracket.
2. Loosen the handles and remove the support bracket from the sawmill track rail.
3. Place the support bracket on the storage bracket located on the sawmill frame between
the first and second bed rails. Tighten the handles to secure the support bracket to the
storage bracket and secure the rubber strap in the bracket hole.

1.2 Remote Sawmill Operation
See Figure 1-3. All sawmill controls operate exactly as described in your sawmill
operator’s manual except the clutch/brake. Instead of pulling a handle to engage the
blade, push the toggle switch on the control panel up. Hold the switch up until the clutch
motor stops completely. The remote clutch mechanism will disengage the brake, rev the
motor to full throttle, and start the blade spinning.
DANGER! Keep all persons out of the path of moving
equipment and logs when operating sawmill or loading and
turning logs. Failure to do so will result in serious injury.
To stop the blade and engage the blade brake, push the toggle switch down. This will also
return the engine to idle.
NOTE: Be sure the toggle switch stays in the up or down position. The boot on the switch
may spring the switch back to neutral. You may need to hold the switch in position until
the remote clutch motor completes its cycle.

1.3 Preparing The Remote Option For Towing
1. After placing the saw head in its traveling position, engage the remote clutch switch to
engage the drive belts. This will keep the engine from bouncing while towing the sawmill.
2. Place the chain support bracket under the cable chain, located between the first and
second bed rails.
See Figure 1-4.
3. Tighten the support handles and secure the chain to the support with the rubber strap.

1-6 ROdoc101921 Remote Operation
1.4 Cold Weather Operation
If the sawmill is operated or stored in freezing conditions, the cable chain may freeze.
Before moving the saw carriage, check to see if the chain is frozen:
1. Remove the chain support bracket (See Section 1.1).
2. Pull the chain up at a few locations to determine if it moves freely. If you detect the chain
is frozen, proceed to the recommended deicing procedure below.
3. If the chain seems to move freely by hand, use the power feed to slowly move the saw
carriage toward the rear of the mill. Since the saw carriage returns only at full speed,
moving the saw carriage forward will allow you to slowly engage the cable chain to be
sure it is not frozen. If you detect the chain is frozen, proceed to the recommended
deicing procedure below.
Recommended Cable Chain deicing Procedure
To de-ice the chain, apply a salt solution (preferably calcium chloride and water) to the
entire length of the chain. Allow the solution to sit until the chain can move freely. The
strength of the solution and time required to free the chain will depend on how cold the
weather is and how much ice has accumulated in the chain.
Before storing the sawmill after using the salt solution, be sure to rinse the salt from any
metal portions of the sawmill frame to prevent corrosion. Refer to the recommended
cold-weather storage procedure below to prevent the chain from freezing.
Recommended Cable Chain Ice Prevention Procedure
Before storing the sawmill in freezing temperatures, apply a 50/50 solution of
environmentally safe antifreeze (Sierra) and water to the cable chain. A garden sprayer
can be used to apply the solution.

1.5 Hydraulic Control Operation
The hydraulic control levers become operational when the contacts at the bottom of the
carriage touch the power strip on the frame tube. The hydraulic control levers will only
work when the cutting head is close enough to the front end of the mill to touch the power
strip.
See Figure 1-5. Hydraulic units have ten control levers to load, clamp, turn and level logs.
Use the hydraulic control levers to get the mill ready to load a log.
DANGER! Keep all persons out of the path of moving
equipment and logs when operating sawmill or loading and
turning logs. Failure to do so will result in serious injury.

1. Move the clamp out and down so it will not get in the way of logs being loaded onto the
bed.
Lower the clamp in/out lever to move the clamp out toward the loading side of the
sawmill.
Lower the clamp up/down lever to lower the clamp below bed level.
2. Raise the log loader lever to extend the legs of the log loader out as far as they will go.
3. The chain securing the log loading arm to the bed frame will be tight. Manually push the
log loader arm until there is slack in the chain.
4. Unchain the loading arm from the bed frame.
5. Manually lower the log loader so it rests on the ground.
CAUTION! Be careful when manually lowering the log
loader. Do not drop the loader onto the ground or perform
any action which might break the velocity fuse valves on
the loader cylinders. These valves control hydraulic flow
and are necessary to prevent the loading arm from
collapsing during use.
6. Lower the loader lever to lower the loading arm as far as it will go. Logs must be rolled
onto the loading arms one at a time.
7. The front, middle and rear toe boards should be below bed level. Once a tapered log has
been loaded, the front or rear end of the log may be lifted to parallel the heart of the log to
the path of the blade.
The front toe board is raised by lifting the front toe board lever up.The middle toe board is
raised by lifting the middle toe board lever up. The rear toe board is raised by lifting the
rear toe board lever up. Once a flat has been made and the log is ready to be turned,
push the appropriate toe board lever down to lower either toe board until it falls below the
level of the bed.

1.6 Loading, Turning, And Clamping Logs
CAUTION! Before loading a log, be sure the cutting head is
moved far enough forward so the log does not hit it.
Damage to the sawmill may result.
CAUTION! Be sure the pivot rails, turning arm, clamp, and
toe boards are below bed level before loading a log onto
the bed. Failure to do so may result in machine damage or
cause misalignment.
To Load Logs
1. Move a log up to the loading arm. Use cant hooks or loading equipment to move the logs
to the foot of the loading arms.
2. Roll the log onto the loader so that it is approximately centered with the sawmill bed. The
log turner will operate much easier if the log is centered on the sawmill bed.
3. Raise the side supports.
4. Raise the loader lever to raise the log onto the sawmill bed. Simply let the loader rise until
the log rolls onto the mill bed.
5. Raise the clamp up (raise the clamp up/down lever) to prevent the log from rolling of the
bed.
6. Lower the loading arm. Leave the loading arm about halfway up while squaring the log.
This will stop the log from rolling off the side of the mill.
WARNING! Always leave loading arm halfway up while log
is on sawmill bed. Failure to do so will result in serious
injury or death.
NOTE: Logs also may be loaded onto the mill with a tractor or other equipment
specifically designed for that purpose.
7. Raise the clamp up to prevent the log from rolling of the bed.
8. Raise the clamp up/down lever.

To Turn Logs
1. Raise the turner lever to engage the log turner arm. Let the arm rise until it touches the
log and starts to turn it.
2. Spin the log against the side supports until it is turned the way you want it for the first cut.
If you want to turn the log more, do the following steps.
3. Engage the clamp by raising the clamp in/out lever. Clamp the log against the side
supports.
4. Lower the turner lever to lower the turner arm below the log.
5. Raise the turner arm to get a new bite on the log.
6. Disengage the clamp.
7. The log can be turned now. Repeat steps 4 through 7 until the log is turned as desired.
To Turn Logs (Optional Procedure)
If you are turning a small cant, you may opt to use the clamp to turn the cant.
1. Lower the clamp up/down lever to lower the clamp below bed level.
2. Raise the clamp in/out lever to move the clamp in, beneath the edge of the cant.
3. Raise the clamp up/down lever to raise the clamp and flip the cant.

To Clamp Logs
1. Raise the clamp in/out lever and clamp the log against the side supports.
2. Lower the turner lever until the turner arm falls below the bed.
3. When the turner arm is lowered all the way, the side supports will begin to lower. Back the
clamp off slightly, and let the side supports come down until they are positioned below the
level of your first few cuts.
4. Lower the side supports, to make few cuts.
5. Us e t he cl a mp i n /o u t le v e r to c lam p t he l o g.
Depending on the log length, front and rear clamp (min. log length - 3.5m), or main clamp
together with front or rear one (with logs shorter than 3.5m) can be used. They allow to
find optimal position of the log on the bed, and prevent distortions during cutting.
1. Raise the front/rear clamp up/down lever to raise the clamp.
2. Raise the front/rear clamp in/out lever to clamp the log.
3. Use the middle clamp in/out lever to clamp the log against the side supports.
4. Lower the front/rear clamp up/down lever to lower the clamp, until the log lays flat on the
bed.
To Level A Tapered Log
Use the toe board lever(s) to raise either end of a tapered log, if desired. Log can be
moved forward or backward using the power roller.
Raise the appropriate lever to raise the front or rear toe board until the heart of the log
measures the same distance from the bed rails at each end of the log.
Pull-Down Clamps
When a cant is being cut, internal stress in the wood may cause the cant to deform
slightly. The cant with internal stress tends to raise on ends. To prevent this, use two
additional Pull-Down clamps. These clamps are mounted at both bed frame ends and if
necessary hold the cant down so it lies flat on the bed.

SECTION 2 MAINTENANCE & TROUBLESHOOTING
2.1 Clean The Cable Chain & Support Tray
As you operate the sawmill, be aware of any pieces of debris that may fall on the cable
chain and/or support tray. Stop the sawmill and immediately remove any pieces of wood,
bark or anything else that may divert the path of the chain or cause it to jam.
Clean the cable chain and support track of sawdust buildup every eight hours of
operation. Blow or brush the sawdust from the track and tray and remove any
accumulated sawdust that is high enough to contact the chain/tray.

2.2 Cable Chain Repair
If a component of the cable chain breaks or is missing, replace the component.
CAUTION! Do not operate the remote sawmill if the cable
chain is damaged or components of the chain are missing.
The chain components are interlocking and continued
operation will cause more damage to the chain.
See Figure 2-1. To disassemble the chain use a screwdriver to pry the connecting links
apart. After removing the connecting links, the side plates can be disassembled by pulling
them apart at an angle.

2.3 Cable Chain And Support Tray Alignment
During each sawmill setup, check the alignment of the cable chain and the support tray:
1. The chain should travel in a straight line. Traveling at an angle will cause the chain to
prematurely wear and break. Check the alignment of the chain by measuring from the
sawmill frame tube to the center of the chain at the top and bottom. The measurements
should be the same (±1/8”).
See Figure 2-2.
Loosen the mounting bolts at the top or bottom of the chain to adjust the distance from the
sawmill frame tube.

2. The chain support tray must be level to prevent premature wear of the chain. Use a
square to check the angle of the tray to the sawmill frame. Check at several locations
along the length of the tray.
See Figure 2-3.
Bend the tray up or down as necessary to square it to the sawmill frame.
