Page 6 WARNINGS Powr-Grip is pleased to offer the most reliable vacuum lifters available. Despite the high degree of security provided by this product, certain precautions must be observed to protect the operator and others. Always wear personal protective equipment that is appropriate for the material being handled. Follow trade association guidelines.
Page 7 OPERATING FEATURES Note: Components featured in the following instructions for assembling, operating or maintaining the vacuum lifter are underlined on their first appearance in each section. Standard FLEXR6HV11DC shown. 1 LIFT SPOOL 7 MOVABLE PAD MOUNT 14 BATTERY GAUGE 2 CONTROL HANDLE 8 VACUUM RESERVE TANK 15 Enclosure with VACUUM SWITCH 3 VACUUM CONTROL VALVE...
Page 8 ASSEMBLY 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) 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 SPECIFICATIONS: Maximum Load Capacity and Lifter Weight).
Page 9 INTENDED USE HARACTERISTICS WARNING: This lifter is NOT intended for lifting hazardous materials, such as explosives or radioactive substances. The operator must verify that the lifter is intended to handle each load, in accordance with the following requirements: • The load must not exceed the maximum allowable weight specified under Load Capacity (see SPECIFICATIONS).
Page 10 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 11 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 12 HANGE THE ONFIGURATION OF ACUUM The lifter can accommodate various load dimensions, depending on the position of the sliding pad arms and movable pad mounts on the pad frame (see illustration in OPERATING FEATURES). Move the pad arms and pad mounts inward or outward on the pad frame as needed to provide adequate support across the load surface.
Page 13 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 harm the pads or prevent them from sealing against the load (see MAINTENANCE: V ACUUM AINTENANCE WARNING: To avoid accidental load release, always center lifter’s pad frame on...
Page 14 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 the vacuum gauge, except when used at high elevations (see SPECIFICATIONS: Operating Elevation). If not, make sure the vacuum switch is adjusted correctly (see MAINTENANCE: V ).
Page 15 Monitoring Vacuum Indicators The low vacuum warning light and the vacuum gauge must remain completely visible to the operator, so that they can be monitored throughout the entire lift. WARNING: Vacuum indicators must be visible to operator throughout entire lift. If the vacuum system experiences leakage while the lifter is attached to the load, the vacuum pumps turn on automatically, as required to maintain sufficient vacuum for lifting the maximum load weight.
Page 16 ELEASE THE ADS FROM THE WARNING: Load must be fully supported before releasing vacuum pads. When the load is at rest and fully supported, move the lever on the vacuum control valve to the back “RELEASE” position: Pull upward on the lever's knob, move the lever all the way (towards operator) and then release it.
Page 17 FTER SING THE IFTER Place the power switch in the OFF ( ) position (blue indicator light shuts off when power is 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;...
Page 18 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 19 • 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). Infrequent Use each time If a lifter is used less than 1 day in a 2-week period, perform the Periodic Inspection...
Page 20 ATTERY The lifter is equipped with a battery gauge to help the operator evaluate whether the battery has adequate energy for lifting. Factors such as the condition of the battery, the time required to execute a lift, and the porosity of the load combine to determine how much battery energy is It is the operator’s responsibility to evaluate these needed.
Page 21 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).
Page 22 ACUUM AINTENANCE Friction Coefficient The friction coefficient represents the lifter's ability to resist load slippage when the load is oriented in any position except horizontal. If the contact surfaces of either the load or the vacuum pads are not clean, dry and in good condition, slippage is more likely to occur. The Load Capacity of most Powr-Grip lifters is based on a friction coefficient of 1 (only Flat Lifters are exempt from this requirement).
Page 23 WARNING: Never use unauthorized rubber cleaners or conditioners to clean vacuum pad. To prevent liquid from contaminating the vacuum system during cleaning, cover the suction hole in the recess for the filter screen or make sure the pad faces downward. Use a clean sponge or lint-free cloth to apply an authorized cleanser and wipe the pad face clean.
Page 24 − L ILTER AINTENANCE ARGE (for 4.4 oz [130 ml] bowl size filters) Filter Function and Conditions Requiring Service An air filter prevents solid particles and liquid from contaminating components in the vacuum system. CAUTION: Examine air filter regularly and empty when necessary. Liquid must not contact any portion of the filter element;...
Page 25 − D DV1032102 ACUUM AINTENANCE YNAFLO WARNING: Before proceeding with any maintenance, disconnect power source. If the vacuum pump takes too long to attain full vacuum, it may require maintenance. Replace the diaphragm, gasket/flap valves or (when preferable) the entire head assembly (see REPLACEMENT PARTS LIST), as necessary to obtain acceptable pump performance.
Page 26 ― T 2907CDC22/12 ACUUM AINTENANCE HOMAS WARNING: Before proceeding with any maintenance, disconnect power source. If the vacuum pump takes too long to attain full vacuum, it may require maintenance (see OPERATING FEATURES for location of pump). Replace the diaphragms, valve flappers or head gaskets as necessary to obtain acceptable pump performance (see REPLACEMENT PARTS LIST).
Page 27 ACUUM WITCH DJUSTMENT Vacuum Switch Function A vacuum switch controls the low vacuum warning light and the vacuum pump (see OPERATING FEATURES for location of vacuum switch): The power switch activates the warning light and the pump, which evacuates the vacuum pads. After the lifter attains a vacuum level sufficient for lifting the maximum load weight (hereafter, “minimum lifting level”), the vacuum switch automatically turns off the pump and the warning light.
Page 28 Adjustment Procedure WARNING: Lifting capacity decreases whenever vacuum switch is adjusted to maintain lower vacuum level. 1) Using a 1/4" open-end wrench (as provided), turn the adjustment screw about 1/6th turn at a time (approximately one flat of the screw head). lower clockwise To maintain a...
