Operation

WARNING: ALWAYS wear eye protection, adequate respiratory and hearing protection, as well as suitable
gloves, when working with this tool.

ignite flammable gas or flammable material, for example paper, wood dust and metal swarf. Ensure the work
area is free of such materials and ensure there is a suitable extinguisher to hand.
IMPORTANT: Ensure the Motor Vents (6) are kept clean during use. Metal swarf and wood dust entering the
tool can damage or destroy it.
IMPORTANT: Stop frequently while operating to clean the work area and prevent a build-up of swarf and dust.
Where possible have a dust extraction system operating around the work area.
