Dismounting of the protective covering
Using the allen key (3 mm) provided, release the four screws
at the lower edge of the covering until it can be pulled up.
Attention!
In order to protect the tipping bucket the dirt
spiral must be inserted in the collection funnel (fig. 3).
Assembly of the tipping bucket
To avoid damage to the tipping bucket during trans-
port, it is separately packed and should be inserted in
the rain gauge on site only after mounting the gauge
on the mast.
For the assembly first you must remove the protec-
tive covering.
Attention!
Do not damage the sharp edges of the tip-
ping bucket and do not bend the middle dividing plate!
When fitting the tipping bucket, proceed with utmost
caution so that the sharp edges of the tipping bucket
are not damaged and the middle wall is not bent!
During operation the tipping bucket lies on the precision buck-
et bearings. To reduce the friction, which is produced at one
tipping, the bearings are made of abrasion-resistant delrin.
The mounted tipping bucket is secured against eventual chang-
es of position by means of two plates.
To insert the tipping bucket, first the relocatable locking plate
C
(fig. 4) must be pushed back.
Now insert the tipping bucket
