SECTION 1 REMOTE OPERATION
1.1 Safety Precautions
IMPORTANT! This manual is provided as a supplement to
the equipment manufacturer’s manual. Refer to the
manufacturer’s manual before attempting to operate this
equipment.
WARNING! Failure to follow the SAFETY PRECAUTIONS
may result in radio equipment failure or serious personal
injury.
CAUTION! Wood-Mizer will not bear responsibility for any
unapproved changes or modifications made to the
equipment.
Installation
CAUTION! PROVIDE A SAFETY CUTOFF SWITCH.
If maintenance is required, the radio must be disconnected
from power. USE PROPER WIRING. Loose or frayed wires
can cause system failure, intermittent operation, machine
damage, etc. DO NOT INSTALL IN HOT AREAS.
This apparatus can be damaged by heat at a temperature
of above 55oC (131oF).
Personal Safety
CAUTION! MAKE SURE THE EQUIPMENT AND
SURROUNDING AREA IS CLEAR BEFORE OPERATING.
Do not activate the remote system unless it is safe to do so.
CAUTION! TURN OFF THE RECEIVER POWER BEFORE
WORKING ON THE SAWMILL. Always disconnect the
remote system before doing any maintenance to prevent
accidental operation of the machine.
Care
CAUTION! KEEP DRY. Do not clean the
transmitter / receiver under high pressure. If water or other
liquids get inside the transmitter battery or receiver
compartment, immediately dry the unit. Remove the case
and let the unit air dry.

CAUTION! CLEAN THE UNIT AFTER OPERATION.
Remove any mud, dirt, concrete, etc. from the unit to
prevent clogging of buttons, switches, etc. by using a damp
cloth.
Maintenance / Welding
CAUTION! DISCONNECT THE RADIO RECEIVER
BEFORE WELDING on the machine the receiver is
connected to. Failure to disconnect will result in destruction
of the radio receiver.
1.2 Control Panel Overview
The LT70DC sawmills can be equipped with the saw head remote control system
(with a wireless control panel). This system allows you to fully control the saw head, i.e.
engage and disengage the blade, the power feed and up/down operation, the blade guide
arm and the debarker as well as to adjust the feed rate.

1.3 Remote Operation
Set up the sawmill as instructed in your sawmill operator’s manual.
Install the charged battery.
Refer to the provided Wireless System manufacturer’s manual for detailed instructions for
installing and charging the battery.
NOTE: When the battery is fully charged, the panel should
run for approximately 20 hours at 20oC.
To turn on the wireless control panel on any DC sawmill:
Make sure that all switches and joysticks are in the neutral or OFF position.
The feed rate dial should be set to the minimum value.
Check that the switch located on the electric box is in the ON position;
NOTE: When the green switch on the electric box is in the
OFF position, the wireless control system is completely
turned off and all sawmill functions can be activated from
the standard control box on the saw head.
Make sure the emergency stop button is released;

Insert the electronic starting key (Air-KEY) into the corresponding socket located on
the left side of the control panel. Turn the key right to the ”1” position.
Push and hold the START button on the left side of the control panel until the panel
working status indicator comes on;
Start the main engine using the key switch located on the sawmill control box
(on the saw head);
Load and clamp the log;
Program the Accuset controller (or PLC-Setworks/SW-10) (See Accuset,
PLC-Setworks or SW-10 Operator’s Manual);
Position the saw head at a height of the first cut;
If necessary, turn the debarker on;
Set the Blade Drive On/Off Switch in the ”ON” position;
Push the left joystick forward and hold it in this position. The blade drive will be
turned on.
Set the feed rate dial to the desired value;
After making the cut, release the left joystick. The blade drive will be turned off and
the main engine will still be running idle.
Position the saw head for the next cut and set the Blade Drive On/Off switch in the
”OFF” position and then in the ”ON” position;
Push the left joystick forward and hold it in this position. The blade drive will be
turned on.
NOTE: As soon as the joystick is released, the blade drive
is disengaged. To engage the blade drive again, set the
blade drive switch in the ”OFF” position” and then in the
“ON” position.
NOTE: If none of the pushbuttons, switches or joysticks is
used within 5 minutes after switching on the transmitter, the
transmitter will turn off automatically.
When sawing is finished, switch the transmitter off by turning the electronic starting key to
the ”0” position. Remove the key and always store it in a safe place.

SECTION 2 DIAGNOSTICS AND MAINTENANCE
IMPORTANT! The description of the Wireless System diagnostics and
maintenance procedures provided below is a supplement to the
equipment manufacturer’s manual. Before maintaining the Wireless
System or performing its diagnostics, read the equipment
manufacturer’s manual.
CAUTION! DISCONNECT POWER SUPPLY FROM THE SAWMILL
BEFORE SERVICING! Always turn the wireless control system off
before performing any sawmill maintenance to prevent accidental
start-up of the machine.
Before starting to perform any diagnostic operation, do as follows:
Bring the transmitting unit close to the receiving unit to avoid any radio interference and
disturbances;
Determine if the existing problem lies with the wireless control system or with the sawmill.
To do that, disconnect the wireless control system using the switch on the electric box (See
Section 1.3) and try to activate the desired functions from the control box on the sawmill. If the
problem persists, it is related to the sawmill control system (not to the wireless control system).
If it does not exist, please refer to the diagnostic procedures described below.

2.3 Maintenance
2.3.1 Daily Maintenance Procedures
Before starting to work:
Make sure that the symbols of all control elements on the transmitter panel are readable.
Replace the transmitter panel if necessary.
Check that the three plates on the transmitting unit are intact and readable.
Make sure that the mechanical operation of the STOP pushbutton is correct.
During normal operation:
Check that there are not any visible damages to the transmitting unit;
Make sure that materials that could endanger the transmitter usage and safety (such as:
sawdust, slabs, concrete, sand, dust, lime) are not accumulated on its surface.
After using the Wireless Option:
Clean the transmitting unit: never use solvents or flammable/corrosive materials and do not
use high-pressure water cleaners or steam cleaners;
Store the transmitting unit in a clean and dry place.
2.3.2 Three-Month Maintenance Procedures
Every three months of operation:
Remove any dust or debris from the transmitter. To do this, never use solvents
or flammable/corrosive materials and high-pressure water cleaners or steam cleaners.
Check that there are not any visible damages to the transmitting unit;
Make sure that the electrical connections between the receiver and the electric box are not
loose or damaged;
Make sure that the receiver panel symbols are readable. Replace the receiver panel
if necessary.
Check that the plates located on the receiving unit are intact and readable.

Six-Month Maintenance Procedures
DIAGNOSTICS AND MAINTENANCE doc042915 2-5

2.3.3 Six-Month Maintenance Procedures
Every six months of operation:
Check if the commands sent by the transmitter are correctly performed by the sawmill.
Make sure that the SAFETY relay contact is open when the transmitter is not sending any
commands. This is critical for the Wireless Option user’s safety. It is necessary to keep a record
(date, signature, comments) showing that this check has been carried out regularly. Keep the
record together with other installation documents.
Make sure that the contacts of all receiver relays are functioning correctly. Check that each
contact closes when the corresponding function is activated and opens when the function is
disabled.
If any transmitter/receiver fault occurs, contact your Wood-Mizer Representative. All repairs of the
equipment should be done by authorized persons only.
