It is recommended to regularly submit the tool to maintenance. Maintenance is also due if the carbon
brushes cut off or if the hammer mechanism fails. When carrying out maintenance all parts of the
maintenance set must be exchanged. Use the appropriate maintenance set for
each machine: PHE 3: 4931 3568 29 (220-240 V), 4931 3568 37 (110 V)
PHE 3 X: 4931 3568 38 (220-240 V), 4931 3568 40 (110 V)
General
Maintenance
With the exception of the electrical parts all parts must be cleaned with cold cleaner. Attention! No
cleaner must enter the encapsulated bearings.
Clean the electrical parts with a dry brush.
Check the dismantled parts for abrasion (visual check) and exchange if necessary.

At each maintenance the tool must be lubricated as shown in the lubrication chart. After having
dismantled the entire tool remove the used grease completely and replace it by new grease. Please
pay attention to the following lubrication chart:
