Operation when using the dust cup (optional
accessory) (Fig. 38)
Operate the tool with the dust cup against the ceiling
surface.
NOTE:
• The dust cup (optional accessory) is intended only for
drilling in the ceramic workpiece such as concrete and
mortar. Do not use the tool with the dust cup when
drilling in metal or similar. Using the dust cup for drilling
in the metal may damage the dust cup due to the heat
produced by small metal dust or similar.
• Empty the dust cup before removing a drill bit.
• When using the dust cup, make sure that the dust cap
is mounted on it securely.
MAINTENANCE

• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
