Model Number: MRTA611LDC Description: Designed for use with a crane or other hoisting equipment, the MRTA611LDC lifter employs vacuum to hold a load for lifting, and it provides manual 360° rotation and mechanically assisted, manual 90° tilt movements for load manipulation. - Page 3 Wood’s Powr-Grip cannot be responsible for the safety of a lifter that has been modified by the customer.

Save the crate for use whenever the lifter is transported. 2) Suspend the lifter from a crane as follows: Select hoisting equipment (crane and hoist, when applicable) rated to carry the maximum load weight plus the lifter weight (see SPECI FI CATI ONS: Maximum Load Capacity and Lifter Weight).
- Page 6 HANGE THE RAME ONFI GURATI ON The lifter offers a variety of pad frame configurations to accommodate different load dimensions and weights (see SPECI FI CATI ONS: Pad Spread and Load Capacity). The following illustration shows several possible configurations. Select a configuration to provide optimal support across the load surface and to minimize load overhang (see OPERATI ON: B EFORE SI NG THE...
- Page 7 Configurations are created by installing or removing the pad frame’s extension arms, by repositioning or removing the movable pad mounts, and by connecting or disconnecting the vacuum hoses to certain vacuum pads. Always assemble the pad frame in a symmetrical arrangement, to keep the lifter balanced (see illustration).
- Page 8 To Reposition ( or Remove) Movable Pad Mounts 1) Remove the cotterless hitch pin from one movable pad mount by pulling on the pull ring. 2) Move the pad mount to the desired position on the pad frame and align the holes for the cotterless hitch pin in the pad mount with COTTERLESS HI TCH PI N the corresponding holes in the pad frame.

Conversely, allowable thickness increases as load weight decreases. I n 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 OPERATI ON: T : About the Tilt Linkage and T ). -
Page 11: Operation
OPERATI ON EFORE SI NG THE I FTER The operator must determine whether the lifter is capable of performing each intended task, in I NSTRUCTI ONS accordance with the SPECI FI CATI ONS and I NTENDED USE sections of this manual. - Page 12 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 MAI NTENANCE: ).
- Page 13 Vacuum Level on Optimal Surfaces When the lifter is attached to clean, smooth, nonporous load surfaces, it should be able to maintain a vacuum level in the green range on both vacuum gauges, except when used at high elevations (see SPECI FI CATI ONS: Operating Elevation). I f not, make sure both vacuum switches are adjusted correctly (see MAI NTENANCE: V ).
- Page 14 I FT AND OVE THE About the Tilt Linkage WARNI NG: Make sure load is positioned correctly on lifter; unbalanced loads may tilt unexpectedly. The lifter’s tilt linkage is designed to automatically hold a balanced load in either the upright or the flat position.

Page 15: In Case Of Power Failure
Monitoring Vacuum I ndicators The low vacuum warning light and both vacuum gauges must remain completely visible to the operator, so that they can be monitored throughout the entire lift. WARNI NG: Vacuum indicators must be visible to operator throughout entire lift. I f the vacuum system experiences leakage while the lifter is attached to the load, the vacuum pump turns on automatically, as required to maintain sufficient vacuum for lifting the maximum load weight. - Page 16 OTATE THE DGEWI SE WARNI NG: Make sure load is positioned correctly on lifter; unbalanced loads may rotate unexpectedly. Remember that the load is longer in its diagonal dimensions than in its side dimensions. Make sure there is sufficient clearance for the load to rotate without contacting the operator or any nearby objects.
- Page 17 ELEASE THE ADS FROM THE WARNI NG: Load must be fully supported before releasing vacuum pads. When the load is at rest and fully supported, pinch the valve release lever against the valve handle, and push the valve handle inward to the “RELEASE” position (power off) until the vacuum pads disengage completely from the load.

Page 20: Battery Test
ATTERY ECHARGE 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). -

I n addition, all pads should be replaced on a regular basis, preferably after no more than 2 years, to ensure that the friction coefficient is not compromised. I f necessary, contact your dealer or Wood's Powr-Grip for more information. I nspection... -
Page 22: Vacuum Test
Cleaning Regularly clean the face of each vacuum pad to remove oil, dust and any other contaminates. Acceptable cleaning agents include soapy water, glass cleaner and alcohol. Do use other solvents, petroleum-based products (including kerosene, gasoline and diesel fuel) or any harsh chemicals for cleaning, because they can damage the pad and create a hazard to the operator or others. -

I LTER AI NTENANCE (for brass bowl type filters) Filter Function and Conditions Requiring Service An air filter prevents solid particles from contaminating components in the vacuum system. CAUTI ON: Examine air filter regularly and empty w hen necessary. Open each filter regularly to determine whether liquid or other contaminants are trapped inside. Remove any liquid or contaminants found in the filter bowl. - Page 24 ACUUM AI NTENANCE (for Thomas pump nos. 107BA20964, 107BD20964 & 107CDC20) WARNI NG: Before proceeding w ith any maintenance, disconnect pow er source.
