Before moving or handling the Treatment Return or Safety Earth turn the power isolator switch on the Power Module to ‘Off’ and turn off the generator. • Hazardous voltages may be present in the treated weed and plants in contact with the treated weed. To protect from any hazardous voltages present in plants in the treatment area you must wear dielectric insulating knee boots capable of withstanding 15 kV (peak) at 50 Hz. The boots must be within any stated expiration date. They must be at least 30 cm tall, in good condition and with a rugged sole. Tuck the hem of your trousers or outerwear into your boots. Do not use RootWave Pro in bare feet, sandals, flip flops, shoes, work boots or normal Wellington boots. Do not attempt to treat weeds close to your feet. Dielectric insulating knee boots can be supplied by RootWave. • Weeds are at hazardous voltages while being treated and may collapse. If it’s necessary to stand in the treatment patch to reach the target weeds, then before treatment, cut down and rake clear any weeds that are over 30cm high. If you’re standing on clear ground and the target weed is short enough that when it collapses it will fall clear of you, then cutting down weeds before treatment is not necessary. To avoid death or serious injury from fire or a burn • After use, the electrode tip of the Treatment Lance and the spike of the Treatment Return may be hot. Before you touch the electrode tip or spike, allow them to cool. • Arcs can ignite dry matter and cause a fire. Do not treat dry weeds or dry plant matter such as dry grass or leaves. Excessive arcing may occur if the electrode is not in direct contact with the target weed, or if the voltage setting is too high for the target weed. Keep Treatment Return in line of site and look for indications of fire. Keep fire suppressant systems available during treatment.

Pro_User_Guide_01_RevC 29 May 2018 To avoid death or serious injury from manual handling, slips trips or falls • The Treatment Return and Safety Earth may resist being pulled from the ground. After disconnecting, use correct manual handling techniques to remove the Treatment Return and Safety Earth from the ground. • The Cables, Treatment Return and Safety Earth can form trip hazards if not properly managed.

Pro_User_Guide_01_RevC 29 May 2018 Overview of RootWave Pro This section provides an overview of RootWave Pro and lists the components. About RootWave Pro RootWave Pro treats weeds by forcing electric current though the weed using a high voltage. The current flow causes a rapid rise in temperature which damages the weed's cellular structure above and below the ground. The weed can then be left to naturally compost. The Treatment Lance targets the electrode tip at the weed's stem, delivering a voltage up to 5 kV at 50 Hz. When activated, the electrical energy provided by the Power Module flows to the Treatment Lance, through the weed, through the soil, into the Treatment Return and back to the Power Module.

Warning Hazardous voltages may be present in the treated weed and plants in contact with the treated weed. To protect from any hazardous voltages present in plants in the treatment area you must wear dielectric insulating knee boots capable of withstanding 15 kV (peak) at 50 Hz. The boots must be within any stated expiration date. They must be at least 30 cm tall, in good condition and with a rugged sole. Tuck the hem of your trousers or outerwear into your boots. Do not use RootWave Pro in bare feet, sandals, flip flops, shoes, work boots or normal Wellington boots. Do not attempt to treat weeds close to your feet. Dielectric insulating knee boots can be supplied by RootWave.

Pro_User_Guide_01_RevC 29 May 2018 2 Check the environment On arrival at the site, assess the treatment area for the following hazards and prepare the site as necessary: • Check the weather and visibility. • Identify any conductive structures above ground such as metal fences, signposts, gates or cables and below ground such as such as gas, water, electricity mains or sewerage systems, assess risk and whether it is safe to treat close to any of these items. • Identify footpaths and rights of way, and whether the treatment area needs to be cordoned off. • Identify any animals that may be near the treatment site. • Identify uneven ground. • Identify any combustible materials, such as dry weeds or dry plant matter. • Identify presence of water. Warning Good visibility is essential for safe operation. Do not use the RootWave Pro in conditions of low visibility, such as thick fog. Pedestrians and animals encroaching on the treatment area can lead to undue hazards. A barrier may be required to control the perimeter of the treatment area. If necessary display signage requesting dogs to be kept on a lead, or close off public access to the treatment area. A second operator may be required to monitor the situation and be ready to press the emergency stop if required. Conductive materials in adjacent structures above ground can conduct hazardous voltages including to zones that are not visible. Do not operate near conductive structures such as metal fences, signposts, gates or cables without first conducting a risk assessment. Conductive materials in adjacent structures below ground can conduct hazardous voltages including to areas that are not visible. Use a cable avoidance tool and signal generator to detect cables or other conductive materials underground such as gas, water, electricity mains or sewerage systems where the risk assessment identifies a potential hazard. Check with land owner whether any maps exist that map underground installations and obtain them if available. Water can conduct electricity. RootWave Pro should not be used in condensing conditions. If the weather conditions become unsuitable then stop, turn off the power source, and re-cover the equipment immediately.

Pro_User_Guide_01_RevC 29 May 2018 Hazardous voltages near water can cause death by electric shock or electric shock drowning. If people are in the water and within 50 metres of the target weed or treatment return do not treat close to water. Do not operate from a position standing in water. Treating weeds close to water can be harmful to aquatic life. Ensure potential impact to aquatic life has been considered before treatment. Uneven ground can cause you to lose control. Conduct a risk assessment before operating on loose, steep or uneven ground and use adequate safety equipment. Caution Electrical arcs can form during treatment and could ignite flammable substances. Do not operate in explosive atmospheres, near flammable liquids, gases or dry materials including dry weeds or dry plant matter. Rake combustible material away from the treatment area. Don’t insert the Treatment Return into or through dry material. Strong magnetic fields created by arcs can interfere with the function of adjacent sensitive electronic equipment. If adjacent equipment appears to function incorrectly then stop treatment and either turn off or relocate sensitive equipment or stop treatment in that area. 3 Prepare weeds for treatment Identify any weeds that you need to prepare before treating. If it’s necessary to stand in the treatment patch to reach the target weeds, then before treatment, cut down and rake to one side any weeds that are over 30cm high. If you’re standing on clear ground and the target weed is short enough that when it collapses it will fall clear of you, then cutting down weeds before treatment is not necessary. Rake away dry dead weeds, litter and potentially combustible materials from the treatment site.

Pro_User_Guide_01_RevC 29 May 2018 Warning Weeds are at hazardous voltages while being treated and may collapse. If it’s necessary to stand in the treatment patch to reach the target weeds, then before treatment, cut down and rake clear any weeds that are over 30cm high. If you’re standing on clear ground and the target weed is short enough that when it collapses it will fall clear of you, then cutting down weeds before treatment is not necessary. Arcs can ignite dry matter and cause a fire. Do not treat dry weeds or dry plant matter such as dry grass or leaves. Excessive arcing may occur if the electrode is not in direct contact with the target weed, or if the voltage setting is too high for the target weed. Keep Treatment Return in line of site and look for indications of fire. Keep fire suppressant systems available during treatment. Caution Electrical current can flow between plants that are in contact with each other. To avoid damage to adjacent plants from the target weeds you may need to cut plants back before commencing treatment. Even if you’re on open ground, it may be easier to treat the weed if it has been cut down first as this may provide better visibility and access to its stem. 4 Connect up Ensure the generator and its output are off. Remove the dust caps on all connectors. Connect the Safety Earth to the Power Module. all-guides com

Pro_User_Guide_01_RevC 29 May 2018 Figure 10 Connect the Safety Earth to the Power Module Connect the Treatment Return to the Power Module using either the Short or Long Treatment Cable.
