Suction cup with piston 10" large capacity 140 kg

SPECIFICATIONS:
Piston suction cups with high suction capacity with vacuum pump and safety indicator.
Thanks to the indicator, these suction cups offer high security, as we can easily see if we are losing grip strength.
Recommended for exclusive work on flat surfaces.
10" suction cup suitable for heavy vehicles.
8" suction cup suitable for cars.

HOW TO USE:
To hold:
1. Position the suction cup handle so that you always see the red line. You should always observe whether the line appears while lifting the load.
2. Pump the rod until the cup adheres completely.
When the red line disappears, the vacuum will be enough to lift.
3. Check the stem frequently to make sure the cup is securely attached. If the red line appears during lifting, immediately lower the load and pump the rod until the line disappears again.

To Release:
1. Place the load on a secure support.
2. Pull the release tabs or press the valve release lever until the cup is completely disengaged.

PRECAUTIONS:
Lifting cups are hand tools and should not be used as a connection to a crane or other lifting devices.
Before each use, check that the suction cup is smooth, clean, undamaged and free of cracks.
Clean the suction cup regularly with alcohol or other non-aggressive cleaning products.
Make sure that the surfaces or objects to be lifted are made of non-porous material. Furthermore, the surface must be clean, free from oils or grease.
On rough or non-porous surfaces the adhesion capacity decreases or is non-existent.
Do not use sharp objects to loosen the suction on surfaces, as this may cause damage to the suction cup.
