SECTION 1 OPERATION
1.1 Safety
CAUTION! 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! 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.
CAUTION! DO NOT INSTALL IN HOT AREAS. This apparatus can be
damaged by heat at a temperature of above 70oC.
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.
CAUTION! IN CASE OF EMERGENCY, immediately press the red
emergency stop switch.
Care
CAUTION! KEEP DRY. Do not clean the transmitter/receiver under
high pressure. If water or other liquids get inside the transmitter
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 Wireless control panel
The LT70 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 Operation
Set up the sawmill as instructed in your sawmill operator’s manual.
Install the charged battery.
Transmitter electronic system constantly controls battery voltage. When it falls below the appropriate
value, the LED indicator light will turn red or an acoustic signal will be heard after which the system
will automatically turn off. In this case, perform the following steps:
Set the saw head in safe position.
Turn the key to the “0” position. The transmitter will be turned off. Remove the key.
NOTE: When the battery is fully charged, the panel should work for
approximately 20 hours at 20oC.
Charging the battery.
To remove the battery, move it forward and lift.
Place the battery in the charger provided by the manufacturer. Use original charger only.
Be sure the charger is connected to the appropriate power supply (220-230V socket or car plug
etc.)
The battery requires about 3-6 hours to be fully charged. Control light CHARGE is on during
charging. When battery is fully charged control light READY illuminates. To charge the battery
fast, push the FAST CHARGE button.
CAUTION! Charger automatically stops charging when the battery is
fully charged. One of the batteries should always be in the charger, as
a spare fully charged battery.
CAUTION! If batteries are not in use for a long time, they should be
charged every 6 months.

To turn on the wireless control panel on any DC (with diesel engine) 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 buttons are released and the feed rate dial is set to minimum
value.;
Insert the starting key (Air-KEY) into the corresponding socket located on the right side of the
control panel. Turn the key right to the ”I” position.
Wait about 3-4 seconds and then push the transmitter activation button.
IMPORTANT! If the emergency stop was pushed at the moment when
the transmitter was activated, or the feed dial was not set to minimum
value, it is necessary to release the emergency stop or set the feed
dial to the minimum value and press the transmitter activation button.
After 3-4 seconds press the transmitter activation button again.
Start the 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

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 upper position;
Push the left joystick forward and hold it in this position. The blade drive will be turned on within
3 seconds.
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.
After position the saw head for the next cut, push the left joystick forward and hold it in this
position. The blade drive will be turned on within 3 seconds.
NOTE: As soon as the joystick is released, the blade drive is
disengaged.
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 starting key to the ”0” position.
Remove the key and always store it in a safe place.
NOTE: The starting key (Air-KEY) stores the receiver identification
data. The transmitter cannot communicate with the receiver without
this key. Do not lose the Air-KEY.

SECTION 2 DIAGNOSTICS AND MAINTENANCE
CAUTION! DISCONNECT POWER SUPPLY FROM THE SAWMILL
BEFORE SERVICING! Always disconnect the remote system before
doing any 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.
