3. SAFETY INSTRUCTION
The Twister 2X system is relatively simple to use. However, it is very important to observe the
proper safety procedures before, during, and after operation. When use properly the Twister 2X
systems will enhance productivity and efficiency in the workplace.
The following instructions should be strictly followed:
1. Make a daily check of the transmitter casing, joysticks and pushbuttons. Should it appear that
anything could inhibit the proper operation of the transmitter unit, it should be immediately
removed from service.
2. The transmitter voltage should be checked on a daily basis. If the voltage is low, the battery
pack should be recharged or replaced (refer to page 23 for battery power status LED display).
3. The emergency stop button (EMS) should be checked at the beginning of each shift to ensure
they are in the proper working order.
4. In the event of an emergency, activate the emergency stop button immediately by pressing the
red EMS button down. This will immediately disconnect the transmitter power and receiver
MAIN relays. Then turned the power “off” from the main power source of the equipment.
5. The transmitter power key, which is located on the right side of the transmitter box, should be
turned “off” after each use and should never left the power key in “on” position when the unit is
unattended.
6. Do not use the same frequency channel and ID code as any other unit in use at the same facility
or within distance of 300 meters.
7. Ensure the waist belt and the shoulder strap is worn at all time during operation to avoid
accidental damages to the transmitter box.
8. Never operate a crane or equipment with two (2) transmitter units at the same time with same
frequency channel and ID code.
