Valve tappet adjustment
The distance of the tappet at the upper side of suction plate (mounting side
operating valve unit) is adjusted to 63 mm (ex works) und secured with locknut.
Never change these distance, otherwise the load (kerb stone) could
fall down. Danger of accidence!
While placing the suction plate on the load/kerbstone, the
installed valve tappet will completely open the flap, which is used
to adjust the hoverimg position without load.
As a result the suction will be easier. In addition to that a higher
level of safety is achieved, while lifting up porous materials or
pick up a load beyond the center of gravity.
If it happens often that the valve tappet gets jammed, while using very dusty, dirty kerbstones/plates/etc.,
you can continuing work without the valve tappet.
Requirements for this are very airtight materials. But this needs to be tested by the user in each individual
case. In case of doubt it is necessary to work ALWAYS with valve tappet and this needs to be cleaned from
time to time..
