Page 9: Assembly
ASSEMBLY ET UP THE IFTER 1) Open the shipping container and remove all materials for restraining or protecting the vacuum lifter. Save the container for use whenever the lifter is transported. 2) If necessary, assemble the lifter's lift bar as follows: One segment of the lift bar can be removed, to reduce overall lifter dimensions for shipping. - Page 10 Note: Some hoisting equipment hooks could interfere with an upright load that extends beyond the lifter's pad frame. If the load would contact the hook during lifter operation, the operator must prevent this by attaching a sling (or other rigging that does not interfere with the load) between the hook and the lift spool.
-
Page 11: T O Change The Pad Frame Configuration
HANGE THE RAME ONFIGURATION The lifter offers a variety of pad frame configurations to accommodate different load dimensions and weights. The following illustrations show all permissible configurations. Select a configuration to provide optimal support across the load surface and to minimize load overhang (see OPERATION: B EFORE SING THE... - Page 12 To support the maximum load weight, all vacuum pads must be installed on the pad frame and the corresponding vacuum hoses must be connected to the vacuum system. To support the largest load dimensions, all extension arms must also be installed on the pad frame. To support smaller weights and dimensions, some extension arms or vacuum pads may be removed, and the provided that the lifter still has corresponding vacuum hoses may be disconnected,...
-
Page 13: To Connect/Disconnect Vacuum Hoses
To Connect/Disconnect Vacuum Hoses The vacuum hose for each vacuum pad is connected to or disconnected from the vacuum system by means of a quick connector. To connect the vacuum hose, push the male and female ends of the connector together until they lock. To disconnect the vacuum hose, move the release ring on the QUICK CONNECTOR female end until the connector separates. -
Page 14: Intended Use
• In order to avoid damaging the vacuum pads, the load's surface temperature must not exceed the allowable Operating Temperatures (see SPECIFICATIONS). However, if such an application cannot be avoided, Wood's Powr-Grip does offer a heat-resistant rubber compound and other solutions which may enable you to lift loads with higher surface temperatures. -
Page 15: Perating Nvironment
Conversely, allowable thickness increases as load weight decreases. In addition, an operator may be able to manually counteract the tendency of unstable loads to tilt out of the upright position, provided that the operator maintains control of the load at all times (see OPERATION: T : About the Tilt Linkage and T ). -
Page 16: 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 17: Confirming The Pad Frame Configuration
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 18: T O Apply The Pads To A Load
PPLY THE ADS TO A Positioning the Lifter on the Load Make certain that the contact surfaces of the load and all vacuum pads are free of any contaminates that could prevent the pads from sealing against the load (see MAINTENANCE: ACUUM AINTENANCE Center the lifter’s pad frame to within 2"... -
Page 19: Reading The Vacuum Gauges
WARNING: Keep apply function activated throughout lift. Note: If a vacuum pad has been lying against a hard object (as during shipping), it may be slightly distorted. Although initially it may be difficult to apply the pad to a load, this condition should correct itself with continued use. -
Page 20: Ift And Ove The Oad
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 21: Monitoring The Low Vacuum Warning Buzzer
Monitoring the 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: Maximum 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 22: 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 23: 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 24: Fter Sing The Ifter
WARNING: If vacuum pads do not disengage completely, do not attempt to move the lifter or load. The operator must never attempt to move the lifter or load until the vacuum pads are completely disengaged, as this could cause an unexpected load release and potential injury to the operator or others. -
Page 25: Maintenance
MAINTENANCE WARNING: Always make sure battery is disconnected before servicing lifter. INSTRUCTIONS Note: One or more wiring diagrams are provided in the final section of this manual for reference when servicing the lifter or trouble-shooting a deficiency. NSPECTION CHEDULE Perform inspections routinely, according to the following frequency schedule: Every-Lift Inspection •... -
Page 26: Infrequent Use
CAUTION: Be sure to use appropriate cleaning methods for each type of electrical component, as specified by codes and standards. Improper cleaning can damage components. • Keep a written record of all Periodic Inspections. If any deficiency is detected during the inspection, correct it before using the lifter. If necessary, return the lifter to Wood’s Powr-Grip or an authorized dealer for repair (see LIMITED WARRANTY). -
Page 27: Aintenance Chedule
AINTENANCE CHEDULE INSTRUCTIONS Unless specified elsewhere in this manual, the lifter does not require maintenance on a routine basis. Instead, maintenance must be performed whenever a deficiency is indicated by routine inspections or tests. Any maintenance warranted must be performed before resuming normal operation of the lifter. ATTERY The lifter is equipped with a battery gauge to help the operator evaluate whether the battery has adequate energy for lifting. -
Page 28: Battery Recharge
Operating the lifter when the battery charger is connected to an AC power source could result in permanent damage to the charger. Only use a battery charger supplied by or approved by Wood's Powr-Grip; other chargers may reduce battery life. Charge the battery as soon as possible after any extended use of the lifter, or whenever the battery gauge indicates diminished energy (see B preceding). -
Page 29: Using A Small Charger
If necessary, contact your dealer or Wood's Powr-Grip for more information. When the charger is used in "NORMAL" mode, it automatically senses the energy level of the battery and reduces the charging rate when the battery is fully charged. -
Page 30: Inspection
Inspection Inspect each vacuum pad for the following deficiencies routinely, as directed in the preceding and T . Correct any deficiency before using the lifter. NSPECTION ESTING CHEDULES • Contaminates on the pad face or sealing edges: Soil build-up can prevent pads from sealing adequately or reduce the friction coefficient (see discussion preceding). -
Page 31: Vacuum Test
ACUUM Test the vacuum system for leakage routinely, as directed in the preceding I NSPECTION ESTING CHEDULES 1) Clean the face of each vacuum pad as previously directed (see V ACUUM AINTENANCE Cleaning). 2) Apply the lifter to a clean, smooth, nonporous surface. The surface should be flat or possess no more curvature than the lifter is designed for (if any). -
Page 32: Air Filter Maintenance
ILTER AINTENANCE (for in-line filters) Filter Function and Conditions Requiring Service This air filter prevents solid particles from contaminating components in the vacuum system. CAUTION: Examine air filter regularly and empty when necessary. Open each filter regularly to determine whether liquid or other contaminants are trapped inside. Remove any liquid or contaminants found. -

Replace the diaphragm or the head assemblies (see REPLACEMENT PARTS LIST), as necessary to obtain acceptable pump performance. -
Page 34: Vacuum Switch Adjustment
ACUUM WITCH DJUSTMENT Vacuum Switch Function Two vacuum switches control various functions of the vacuum lifter (see OPERATING FEATURES for location of vacuum switches). While the lifter is powered up, each vacuum switch senses the vacuum level in one of the two vacuum circuits of the vacuum system. If either circuit loses significant vacuum while the lifter is in the apply mode, the system responds automatically. - Page 35 • n_3 = -430. This setting turns off the low vacuum warning buzzer, light and/or strobe light and turns on the vacuum lift light, indicating that the lifter has already reached the minimum vacuum level (see n_4). Setting n_3 must always be set above n_4. •...
