Product Description

Hand cups use vacuum to lift and carry loads, as follows: A manual pump

removes air from between the rubber pad and the contact surface; an audio alarm

and a red line on the pump's plunger serve as low vacuum indicators; a check

valve allows the user to repump the cup without removing it from the contact

surface; and a release mechanism allows the cup to disengage completely.

Model Pad Nominal Dia. Max. Load Capacity*

LJ6VHWBP LJ6 6" [15 cm] 70 lbs [32 kg]

N4950WBP G0695 8" [20 cm] 125 lbs [57 kg]

N5450WBP G0725 9" [23 cm] 150 lbs [68 kg]

N6450WBP G0750 10" [25 cm] 175 lbs [79 kg]

*Maximum Load Capacity includes a 3:1 safety factor and requires the following:

attachment on clean, smooth, nonporous at surfaces; a minimum vacuum level

of 17½" Hg [-59 kPa]; and a friction coe󰀩cient of 1. This rating is based on tests

of new hand cups attached to the upper, horizontal surface of static objects in

ideal conditions. Many factors can reduce the capacity, including: lifting a load

when the cup is attached to a vertical or inclined surface; or lifting a load that

applies leverage to the cup. See www.WPG.com for more information.

Low Vacuum Audio Alarm

Volume: 70 dBA at 36" [91 cm]

Power Source: one AAA size, 1.2-1.5-volt alkaline battery; automatic on/o󰀨

function

Load and Environmental Conditions

Use the cup on clean, relatively smooth, nonporous surfaces, at temperatures

from 10° to 120° Fahrenheit [-12° to 49° Celsius]. Moisture or contaminants

can reduce the slip resistance of the cup. Excessive exposure to moisture can

also damage the audio alarm or reduce its life. The red-line indicator and audio

alarm may not perform reliably at elevations above 5000 feet [1524 meters]; see

MAINTENANCE: Service.

OPERATION

To Test Audio Alarm

Prior to using the hand cup, make sure the audio alarm is functioning correctly

and can be heard clearly over ambient sound in the work environment: While

leaving the sound emission holes uncovered, depress the plunger slightly. The

audio alarm should sound; if not, see MAINTENANCE: Service.

To Attach Hand Cup

1) Position the cup on the contact surface so the red line will be visible if it

should appear while lifting the load. CAUTION: Test the cup for staining or

deformation of load surfaces with light colors or soft coatings.

2) Pump the plunger until the cup attaches completely. When the red line is

hidden and the audio alarm is silent, vacuum is su󰀩cient for lifting.

3) Check the plunger frequently to make sure the cup remains securely

attached. If the red line appears or the audio alarm sounds while lifting, set

down the load immediately and pump the plunger until the red line is hidden

and the audio alarm is silent again (see WARNINGS).

To Release Hand Cup

1) Set the load on a secure support.

2) Pull one of the release tabs (on 6" [153 mm] cups) or press the valve

release lever (on other cups) until the cup disengages completely.

CAUTION: Remove the cup when not in use.

MAINTENANCE

Service

Since aging and wear reduce the capacity of the rubber pad, it should be replaced

at least once every 2 years or whenever damage is discovered (see Inspection).

If the audio alarm does not function normally (see OPERATION), make sure a

working battery is installed correctly (see TO REPLACE BATTERY, overleaf). If

the condition persists, contact an authorized dealer or visit www.WPG.com for

assistance.

If the hand cup does not function normally, the cup face may be dirty or the cup

may require service. First clean the cup face according to the directions to follow.

If the condition persists, contact an authorized dealer or visit www.WPG.com for

assistance.

Cleaning

1) Remove the air lter from the cup face.

2) Use a clean sponge or lint-free cloth to apply soapy water or another mild

cleanser to the cup face; see WARNINGS and www.WPG.com for more

information. CAUTION: To prevent liquid from contaminating the pump,

hold the cup face-down or cover the suction hole in the lter recess.

3) Wipe all residue from the cup face.

4) Allow the cup to dry and reinstall the air lter.

Inspection

Examine and test the cup regularly to make sure it does not exhibit the following

faults:

• failure of audio alarm to function correctly (see OPERATION).

• corrosion or other indications of battery leakage inside battery chamber

(see TO REPLACE BATTERY, overleaf).

• cuts or damage to sealing edges of rubber pad.

• cracks or dents in handle or pump.

• reappearance of red line soon after attaching cup.

• sluggishness or dramatic changes in pump action.

• excessive glaze or sti󰀨ness of rubber pad.

• air lter missing from cup face.

Correct any faults before using the cup (see Service).

Storage

Store the cup in clean, dry condition within its protective carrying case. If the

cup is used once a month or less often, remove the battery (see TO REPLACE

BATTERY, overleaf) and store it separately, to prevent corrosion.

WARNINGS

Failure to observe WARNINGS could damage the hand cup or the load, or cause

injury to the user.

• Do not use the cup to lift loads that exceed the Maximum Load Capacity or

the e󰀨ective capacity (see SPECIFICATIONS).

• Do not use the cup to support a person.

• Do not place the cup face against surfaces which could damage the sealing

edges.

• Avoid conditions that could cause the cup to slip or to disengage

prematurely, such as: contaminants, cuts or scratches in the cup face or

contact surface; applying the cup to porous materials; or applying pressure

against the cup edge.

• Do not use the cup to lift when the red line is visible or the audio alarm

is sounding. If the red line reappears or the audio alarm sounds frequently,

discontinue use and see MAINTENANCE: Service.

• Do not allow anything to interfere with free movement of the plunger while

the cup is attached.

• Do not touch the release tabs (on 6" [153 mm] cups) or the valve release

lever (on other cups) while lifting.

• Do not attach 10" [254 mm] diameter cups to thin, fragile materials.

• Do not use harsh chemicals (such as solvents or gasoline) or unauthorized

rubber cleaners and conditioners to clean the cup.

• Avoid contact with battery leaks because they contain chemicals that could

damage eyes, skin, clothing or the plunger assembly.

• Do not expose a battery to excessive heat (see SPECIFICATIONS:

Environmental Conditions), because this could cause the battery to explode.

See overleaf for SPECIFICATIONS, OPERATION, MAINTENANCE and

WARNINGS.

TO INSTALL PLUNGER ASSEMBLY

Grasp the head of the old plunger assembly and

pull it straight out from the handle. If the plunger

assembly is too tight to be removed this way,

return the hand cup for repair.

Wrap a small dowel or rod with a soft, lint-free

cloth and wipe the inside of the handle, to

make sure it is clean and dry (lubricant-free).

Carefully examine the inside of the handle for

scratches and contaminants, using a ashlight

for illumination. Scratches between the mid-

point and the closed end of the handle can cause leakage. Scratches near the

open end of the handle rarely present a problem. Make sure that no old lubricant

remains inside the handle.

Using a soft swab, apply a ring of new lubricant

around the inside of the handle, at a point about 1"

[25 mm] from the closed end. Keep the open end

of the handle as dry (lubricant-free) as possible.

Silicone lubricant is recommended; contact Wood's

Powr-Grip Customer Service to order this. Do not

use improper lubricants in the handle.

Insert the U-cup

end of the plunger

assembly into the

handle, and push

until the plunger assembly begins to tighten;

then seat the plunger assembly with one strong,

swift motion. Operate the plunger, turning it to

spread the lubricant thoroughly on the U-cup.

Then leak-test the hand cup as directed in the

following section.

TO LEAK-TEST HAND CUP

Attach the hand cup to a clean, smooth, scratch-

free piece of glass or metal for approximately 2 hours. The audio alarm and the

red line on the plunger serve as low vacuum indicators: If the audio alarm does

not sound and red line does not appear during the test period, the cup is usable;

if the audio alarm does sound or the red line does appear, discontinue use until

the problem is corrected. See MAINTENANCE: Service (overleaf) for more

instructions.

TO REPLACE BATTERY

Test the audio alarm regularly (see OPERATION: To Test Audio Alarm, overleaf)

and replace the battery as necessary. CAUTION: Follow the battery manufacturer’s

instructions for correct handling, storage and disposal of batteries.

1) Hold the plunger and turn the plunger cap counter-clockwise to loosen it.

2) Remove the plunger cap and the old battery.

3) Install a new battery in the battery chamber, making sure to orient the positive

end (+) toward the red line and the negative end (-) toward the plunger cap.

CAUTION: Do not reverse battery polarity, because the audio alarm will not

function.

4) Reinstall the plunger cap, turning clockwise to tighten it securely.
