Maintenance

General instruc-
tions
These instructions concern general maintenance work. Specific
maintenance work procedures for each machine will be described
later. When performing all maintenance work the machine must be
secured
in the transport position. If the working position is necessary for
performing maintenance work, you will find appropriate instructions
concerning
this work.
Working with grease gun
Lubrication is performed by one or two pumps with the grease gun. If
you feel resistance after just one pump on the lubricant spray do not
apply more grease to the bearings. Too much grease bearings drift
apart. This can result in dust and dirt entering the bearings and
causing premature wear and tear.

contractor, maintenance should be performed more often. In work conditions with
heavy dust development, maintenance should also be performed more often.
