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).  However, a vacuum pad's ability to maintain this friction 

coefficient is reduced by factors such as contamination, wear, age and exposure to sunlight, as 

well as the condition of the load's contact surface (see INTENDED USE: L

OAD 

C

HARACTERISTICS

).  

Pads that have surface contamination must be thoroughly cleaned (see Cleaning discussion to 

follow).  Over time, the rubber in a pad may experience hardening or leaching of chemicals, 

resulting in stiffness or surface glaze.  Pads that exhibit wear, stiffness or glaze must be replaced. 
In 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.  If necessary, contact your dealer or 

Wood's Powr-Grip for more information. 

Inspection 

Inspect each vacuum pad for the following deficiencies routinely, as directed in the preceding 

I

NSPECTION 

and T

ESTING 

S

CHEDULES

.  Correct any deficiency before using the lifter. 

• Contaminates on the pad face or sealing ring:  Soil build-up can prevent pads from sealing 

adequately or reduce the friction coefficient (see discussion preceding).  Follow the directions 

to clean pads as necessary (see discussion to follow). 

• Filter screen missing from pad face:  This screen helps prevent debris from plugging the 

vacuum hose and the air filter.  Replace any missing screen immediately (see REPLACEMENT 

PARTS LIST). 

WARNING:  Replace any sealing ring that has any nicks, cuts, abrasions or other 

deterioration. 

• Nicks, cuts, abrasions other deterioration in sealing rings:  Pad damage can reduce the lifting 

capacity.  Replace any damaged sealing ring immediately (see discussion to follow). 

Cleaning 

Regularly clean each vacuum pad to remove oil, dust and any other contaminates.  Acceptable 

cleaning agents include soapy water and other mild cleansers.  Do 

not use solvents, petroleum-

based products (including kerosene, gasoline and diesel fuel) or any harsh chemicals for 

cleaning.  Do 

not use unauthorized rubber cleaners or conditioners, such as those intended for 

cleaning tires or vinyl surfaces, because those products can leave a hazardous film on vacuum 

pads which significantly reduces their lifting capacity (see Friction Coefficient preceding).  The 

use of any unauthorized cleaning agent is prohibited because it could damage the pad and/or 

create a hazard to the operator or others. 

WARNING:  Never use solvents, gasoline or other harsh chemicals to clean 

vacuum pad. 

WARNING:  Never use unauthorized rubber cleaners or conditioners to clean 

vacuum pad.
