Cut-off grinding
Risk of injury!
When using cutting discs, splinters may come away from the cutting disc during cutting and spin off. When
cutting, we recommend use the special protective cover.
High risk of injury!
Fragments of cut-off discs may be projected at a very high velocity.
- Do not apply any lateral pressure to the disc as the cut-off disc may tilt and burst.
1.Remove the protective special cover
2.Attach the protective cover
3.Mount a cut-off disc.
4.Turn on the device and allow it to run without applying a load.
5.Hold the motor block at an angle of 300 to 450 to the work piece.
6.Slowly and evenly run the disc along the designated cut-off line.
CLEANING AND MAINTANCE
Before any work on the machine itself, pull the mains plug. For safe and proper working, always keep the
machine and ventilation slots clean. In extreme working conditions, conductive dust can accumulate in
the interior of the machine when working with metal. The protective insulation of the machine can be
degraded. The use of a stationary extraction system is recommended in such cases as well as frequently
blowing out the ventilation slots and installing a residual current device (RCD). Please store and handle
the accessory(-ies) carefully. If the machine should fail despite the care taken in manufacturing and testing
procedures, repair should be carried out by an after-sales service centre for Maxpro power tools.
ENVIRONMENT
Do not dispose of electric tools, accessories and packaging together with household waste material -
in observance of European Directive 2002/96/EC on waste of electric and electronic equipment and its
implementation in accordance with national law, electric tools that have reached the end of their life must
be collected separately and returned to an environmentally compatible recycling facility.
