ARE IN A POSITION TO ALLOW FOR THE UP AND DOWN MOVEMENT OF THE
2 ATTACHED BOATS .
Personal water craft models can be attached at
either end.
2. Pressing the tru-lock extension button to one
side or the other, allows the extension of the opposite Gripster
end to the desired position for the connection to the companion
vessel. Release the tru-lock and activate the vacuum pump body
by pumping (5-8 times) on the second boat.
3.If at any time the red safety line appears on
pump body, re-pump device and/or find a better attachment point.
4.As with any mooring device, we recommend a backup
attachment should your vessel be unattended for an extended period
of time.
5. Make sure the vacuum pump area is free of dust
and or debris to provide the best adhesion.
