Unscrew the 4 bolts (2) so the motor with flange and coupling can be taken off.
Check the buffer (4) and replace if necessary. (Part number E07782)
.
Check the seals (5) around the drum housing for any damages.
6.2
Maintenance of bearings
Both bearings in the drum housing are open bearings which are covered by special designed shaft seals.
These bearings should be greased to keep the dust out of the bearings.
By normal daily use the bearings should be greased once a month.
The quantity of used grease should be 5-10 gram. This is equal with 2-6 pumps of grease (on points 6 & 7)
Be careful! Too much grease is not good for the bearings!
Only use the grease which is recommended by
Blastrac, this is E08729 – bearing grease.
This grease is specially made for this kind of
application. Using other grease will damage the
bearing.
