Maintenance and care

When driving over uneven area mind, that the lift arm of the support frame does not begin for
hopping!
•
There is the danger that the gripping good (manhole/cone) could break apart by the tension
force (from inside).
•
It exists the danger, that the distance between gripping good (upper edge of manhole) and
lower edge of stabilizer and/or brackets becomes larger that than 15 mm.
In this case lower gripping good on the ground immediately and grip it again.
•
Transport the device (SVZ-UNI) with the gripped gripping good (manhole/cone) to the destination and
lower it carefully.
•
Relieve chain suspension/load hook at support frame (excavator), until load tie rod on device (SVZ-uni-
F) slips downward.
•
Move device lifting hook by diagonal pulling of load tie rod in position "release" (Fig. 1).
•
Bring the device (SVZ-UNI) out of the gripping good (manhole).
