The unit is a powerful machine with moving parts, and is capable of causing personal injury if proper precautions are not this reason, throughout this Manual , we have pointed out some of the hazards which may occur as you use the unit. We have also listed the instructions or precautions you should take to avoid these hazards.

9 In some cases, we have also pointed out the consequences which may occur if you do not follow these instructions or precautions. We will use the following system to identify the severity of the hazards:DANGER! Immediate hazard which will result in severe personal injury or ! Hazard or unsafe practice which could result in severe personal injury or ! Hazard or unsafe practice which could result in minor personal injury or property read and follow this instruction Manual , including all safety instructions and precautions, carefully and apcu Owner s ManualSafety DevicesThis unit has two kinds of safety devices. Guard fences protect each side of the unit. These are designed to keep everyone away from the moving parts of the unit while it is Operating . These guards should always be in place when the unit is Operating normally. There may be some cases where you will want to do Maintenance work with the safety guards removed.

10 You should be especially careful during these procedures. As the load enclosure moves up and down, pinch points are created where the moving parts meet. If you are standing too close to the load enclosure when it is moving, your arm or leg may be caught in the moving parts, and you may be hurt. Stay away from the pinch points when the safety guards are removed and the load enclosure is moving. Always replace the safety guards as soon as you are done with the Maintenance work. The unit also includes three photo-eye systems. Each photo-eye system includes a light source on one side of the unit, and a reflector on the other side. If any of the light beams is broken, the unit will not start, and the load enclosure will not move. This helps to ensure that everyone is out of the way before the load enclosure moves. Before using the unit, please be sure that the guards are in place, and that the photo-eye system is work-ing.
