PERATING NVIRONMENT The operator must determine whether the lifter is intended to be used in each work environment, in accordance with the following restrictions: WARNING: Never use lifter in dangerous environments. • This lifter is not intended for use in any environment that is inherently dangerous to the operator or likely to compromise the lifter's ability to function. -
Page 12: Operation
OPERATION EFORE SING THE IFTER The operator must determine whether the lifter is capable of performing each intended task, in INSTRUCTIONS accordance with the SPECIFICATIONS and INTENDED USE sections of this manual. In addition, all of the following preparations must be completed prior to lifting any load. Taking Safety Precautions The operator must be trained in all relevant industry and regulatory standards for the operation of the vacuum lifter in its geographical location (eg, ASME B30.20 in the USA). -
Page 13: T O Apply The Pads To A Load
CAUTION: Examine each air filter regularly, and empty when necessary. Two air filters help protect the vacuum generating system from contaminants. However, the lifter is not intended for use on wet load surfaces because the filters would not prevent liquid from entering the vacuum system. -
Page 14: Reading The Vacuum Gauges
Reading the Vacuum Gauges The lifter is equipped with 2 vacuum gauges, which indicate the current vacuum level in each green circuit of the lifter’s vacuum system. The range indicates vacuum levels sufficient for lifting the maximum load weight, whereas the range indicates vacuum levels that are sufficient for lifting the maximum load weight. -
Page 15: Positioning The Lift Bar
IFT AND OVE THE Positioning the Lift Bar WARNING: Lift bar must be oriented vertically to lift load. Never lift the load from a flat position with the lift bar latched parallel to the load. Always disengage the tilt latch (see T ILT THE follow) and raise the lift bar to a vertical orientation before attempting to lift. -
Page 16: Low Vacuum Warning Buzzer
Low Vacuum Warning Buzzer Using the low vacuum warning buzzer requires minimal interaction from the operator. The warning buzzer sounds an alarm until the lifter attains sufficient vacuum to lift the maximum load weight (see SPECIFICATIONS: Load Capacity). After the lifter has attained this vacuum level, the alarm stops sounding, to indicate that the lifter is ready to lift the load. -
Page 17: T O Rotate The Load Edgewise
OTATE THE DGEWISE WARNING: Never disengage both the rotation latch and the tilt latch at the same time. This lifter is not designed for rotation and tilt functions to be used at the same time. Disengaging the rotation and tilt latches simultaneously could cause uncontrolled and unpredictable load movement, potentially resulting in load damage or injury to the operator. -
Page 18: T O Tilt The Load
ILT THE WARNING: Never disengage both the rotation latch and the tilt latch at the same time. This lifter is not designed for rotation and tilt functions to be used at the same time. Disengaging the rotation and tilt latches simultaneously could cause uncontrolled and unpredictable load movement, potentially resulting in load damage or injury to the operator. -
Page 19: After Using The Lifter
FTER SING THE IFTER Leave the valve handle in the “RELEASE” position (power off). CAUTION: Do not set the lifter against any surfaces which could soil or damage the vacuum pads. Use the hoisting equipment to gently lower the lifter onto a stable support; then detach the hoisting equipment hook from the lift bail. -
