8.3. Maintenance Plan
The first maintenance should be performed after 250,000 cycles with non-lubricated
air (dry-running) and after 500,000 cycles with lubricated air (standard operation).
In most cases the service interval may be prolonged. However under unfavorable applica-
tion conditions it may also be necessary to reduce the interval. When re-assembling the
screwdriver afterwards, we advise to do about another 30 operating cycles before setting
the required torque, in order to allow a possible seating process of the internal clutch parts.
IMPORTANT
Make sure to fix the servicing intervals in accordance with the degree of use
of the machine and the respective application.
