The large rubber pad area of over 50 square inches makes full face contact when the Lifter is pumped, and allows attachment to glass of varying thickness with very little risk of damage.
To release the S7950 Lifter from the surface, simply press the vacuum release lever (which is protected by a guard during use) and the pad detaches from the surface without any residual sticking. Four 5/16" (7.9 mm) diameter holes in the handle are convenient locations to attach guide ropes when using these Vacuum Lifters mounted on one of CRL's Manual Lifting Frames, as well as for other utility attachments.
Instructions for Troubleshooting:
Remove the six screws to separate the handle and the rubber pad. Then, inspect the handle and the rubber pad separately.
1. Check if the issue is related to the rubber pad:
- Attach the rubber pad to a functioning handle, then test by pumping.
- If the issue is resolved, the problem lies with the disassembled handle.
- If the issue persists, the problem is with the rubber pad. Likely causes include excessive dust or hair on the sealing edge or wear on the sealing edge of the rubber pad.
2. Check if the issue is related to the handle:
- Block the air inlet of the handle using a finger or a pipe sealed at one end and pump, then observe the plunger.
- If the plunger does not move outward, the issue is with the disassembled rubber pad.
- If the plunger moves outward, the problem lies with the disassembled handle. The likely cause includes the evaporation of silicone grease inside the handle.
