STEPCRAFT MM-800 - 6 Service and Maintenance; Storage

-11-
If the power tool is overloaded, the calculated remaining runtime is displayed flashing in red (RD).
If the remaining runtime is not sufficient for your application, reduce the load or feed rate to be able to switch
back to continuous operation.
5.4.2 Display of remaining runtime in the PV design
If the power tool is in “portal mode”, the remaining runtime can be queried via the PV interface in addition
to the visual display.
The bottom table shows the correlation between the remaining runtime and the associated output variables.

6 Service and maintenance
Danger
Pull the power plug during service work.
STEPCRAFT machines are designed to be low in maintenance.
Replace the carbon brushes at the latest after 125 - 150 operating hours. The spare parts can be
referenced in chapter 9.
The ball bearings used are greased for life. When the machine has been in operation for a longer period
of time, we recommend to hand the machine in at an authorised STEPCRAFT customer service shop for
inspection.
6.1 Storage
If the power tool is not used for a longer period of time, it has to be carefully cleaned. Spray bright metal
parts with a rust inhibitor. Close the portal connector with the supplied covering cap Z (Fig. 3).
