9.4 Cleaning
Use cleaning solvents to clean the vacuum tube lifter
J
UMBO
(not petroleum ether or corrosive liquids;
the use of petroleum ether or corrosive liquids could cause leaks in the supply hose or lift tube). The
suction plates can be cleaned using soap and warm water; do not use cleaning solvents on the
suction sealing lips!
9.5 Operator handles
The two operator handles of the vacuum tube lifter
J
UMBO
both feature a dust filter that filters the
ambient air that is sucked into the valve unit when lowering the lift tube.
If this filter is blocked, the vacuum tube lifter
J
UMBO
can no longer be lowered and it will not be
possible to release the workpiece from the suction pad. A slow lowering of the vacuum tube lifter
J
UMBO
in the “Release” position of the control lever/handle is an indication that the filter is soiled or
blocked.
