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.
6.5 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. → page 23
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.
2. Slacken the positioning screw.
3. Set distance "X" between the tip of the accessory tool and the tip of the depth gauge.
4. Tighten the positioning screw.
6.6 Using parallel guide
CAUTION
Risk of injury and damage due to accessory tool. If parallel guide and accessory tool come into contact,
damage to the parallel guide and/or the accessory tool can result.
▶ Always set the parallel guide to a position where it cannot come into contact with the accessory tool.
The parallel guide can be used as a cutting guide or as a depth gauge.
Using parallel guide as cutting guide
Use the parallel guide to make straight cuts paralleling an edge.
If applicable, make sure that clamps do not obstruct the free movement of the multitool.
WARNING
Risk of injury and damage due to kickback. If a corner of the accessory tool comes out below or above
the workpiece, kickback occurs and can lead to loss of control.
▶ Make sure the accessory tool remains fully plunged in the workpiece over the entire stroke (oscillation).
▶ Install the securing collar and the parallel guide. → page 23
▶ Make sure that the parallel guide is parallel with the accessory tool.
▶ Slacken the clamping screw of the securing collar.
▶ Turn the securing collar so that the accessory tool will plunge into the workpiece at an angle.
▶ Retighten the clamping screw.
▶ Open the positioning screw.
▶ Set a cutting depth at which the accessory tool remains fully plunged in the workpiece over the entire
oscillating stroke.
▶ Tighten the positioning screw.
▶ Position the multitool with the parallel guide on the edge. Guide the multitool along the edge for the full
length of the cut.
