6.4 Working with the multitool
WARNING
Risk of injury and damage. Misshapen, dulled or otherwise damaged accessory tools can break and cause
injuries or damage to property.
▶ Do not use worn or damaged accessory tools.
The multitool is designed for a multiplicity of tasks. Depending on the accessory tool installed, you can use
the product to saw, sand/grind or scrape or to remove grout.
Cutting
Plunge-cut saw blades are ideal for precision cuts in tight spaces, close to edges or flush with a surface.
▶ Set the multitool to a medium speed stage. This gives you more control for plunge-cutting.
▶ After making the initial plunge cut, you can select a higher speed stage for faster progress.
▶ Apply moderate pressure and do not force the accessory tool into the material. Severe vibrations during
the plunge stage of the cutting process are a sign that you are applying too much pressure.
Grinding
▶ After switching on, allow the product to reach its full oscillation frequency before you touch the accessory
tool against the workpiece.
▶ Lift the product clear of the workpiece before switching off.
▶ When sanding or grinding, use a continuous movement and apply light pressure. Use the entire
sanding/grinding surface, not just the tip.
▶ Rotate the backing pad at regular intervals. This will enable you to achieve even wear of the abrasive
accessory tool and the backing pad.
