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.

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 by new grease. For

assembly a total of 350 g of grease is necessary. Please pay attention to the following lubrication chart:

It is recommended to submit the tool to maintenance after every 150 work hours, if the hammer

mechanism gets weak, or if the carbon brushes switch off.“When carrying out maintenance all parts of

the maintenance set 9170 3180 30 must be exchanged.

Maintenance

Lubrication

General

Check the dismantled parts for abrasion (visual check) and exchange if necessary.

Before assembly submit all relevant parts to an electrical examination (see chapter Electrical and
