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.

Display of the 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.

Service and maintenance
Danger
Pull the power plug during all service work.
MAFELL 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 MAFELL 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. 4).

Troubleshooting
Danger
Determining the causes for existing defects and eliminating these always requires
increased attention and caution. Pull the mains plug beforehand!
Some of the most frequent defects and their causes are listed in the following chart. If case of other defects,
please contact your dealer or the MAFELL customer service directly.
