5.1 Lifetime of the machine
Regular inspection, repair and the replacement of worn or defective
parts in good time will prolong the life of the machine.
“Prevention is better than repair”, therefore ensure:
5.1.1 Correct usage.
5.1.2 Regular cleaning.
5.1.3 Oil changes at the correct intervals.
5.1.4 Periodic safety inspection.
5.2 Lubrication and oil change
Under normal conditions the machine requires no lubrication (except
