To change the speed, first switch off the tool and then

any work on the tool.
Installing or removing the saw blade
CAUTION:
• Always clean out all chips or foreign matter adher-
ing to the blade, blade clamp and/or slider. Failure
to do so may cause insufficient tightening of the
blade, resulting in a serious injury.
To install the saw blade, always make sure that the blade
clamp sleeve is in released position before inserting the
saw blade. If the blade clamp sleeve is in fixed position,
rotate the sleeve to the released position.

removed and the blade clamp sleeve is fixed at the
released position.

• If you remove the saw blade without rotating the
blade clamp sleeve fully, the sleeve may not be
fixed. In this case, rotate the blade clamp sleeve
fully, then make the sleeve fixed at the released
position.
