VB250 PARTS MODIFICATION
The VB250 experienced a parts modification in 2008. The model you have can be determined by the
drive shaft with the current model having a flat spline of approximately 20mm. This range of
electroportables has been exclusively designed to make the assembling and disassembling of all the
parts easier, especially of those that have to be handled frequently because of cleaning and
maintenance purposes.
For the assembling/disassembling of the parts, first place the machine in the vertical position, with
the blade looking up. The blade is inserted into the lowest extremity of the transmission shaft with
the help of a screw. For assembling/disassembling, the operator only needs a screwdriver. To
handle the blade in a safe way, hold it always with a safety glove/thick cloth (Step 1, Figure 1).
The blade guard is attached to the tube by a thread. To detach it, turn it in the direction of the
arrow (Step 2, Figure 1). Once the blade out of the guard, the transmission shaft, the bearing bush
and the joints will be free to be taken out (Step 3, Figure 1).
To reassemble the set, insert the transmission shaft with the bearing bush and the inner joint in the
tube till it clicks. Press the bearing bush. If it does not enter totally (keeps about 10 mm out), turn
and push the shaft following the Step 4, Figure 1 till the bearing bush is totally in. To finish, thread
the guard with the outer joint in the tube and follow Step 1 in the opposite way of the
disassembling.

REMARK: To thread the screw, align the cavity of the shaft with that of the blade and place the blade
on the shaft extremity level (Figure 2).
