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.
Scraping
Set the multitool to a low to medium speed stage.
Position the accessory tool at the point where material has to be removed.
Apply moderate pressure. Excessive pressure can result in damage to the underlying material.
Removing grout
Before starting work measure the width of the grouted joint and select an appropriate accessory
tool.
Set the multitool to a medium to high speed stage.
Use a back-and-forth movement and remove the grout in multiple passes.
Make sure that the accessory tool is in line with the joint and do not apply too much sideways
pressure to the accessory tool during the operation.
Use the carbide-grain edging on the accessory tool as an indicator for plunge depth. To avoid
damaging the underlying material, do not go deeper than the line where the carbide-grain edging
stops.
Using depth gauge
CAUTION
Risk of injury and damage due to accessory tool. If depth gauge and accessory tool are allowed
to touch each other this can result in damage to the depth gauge and/or the accessory tool.
Always set the depth gauge to a position where it cannot come into contact with the accessory
tool.
The depth gauge enables you to control the plunge depth, for example when you plunge cut and
need to make sure that objects or surfaces behind the workpiece are not damaged.
1.Install the securing collar and the depth gauge.
If the accessory tool is set at an angle, slacken the clamping screw and turn the securing
collar until the depth gauge parallels the accessory tool. Retighten the clamping screw.
