Makita LS1216 Manual

Specification
LS1216, LS1216L
Slide Compound Saw 305mm (12")
LS1216 and LS1216L are upgraded sister tools of LS1214 series models,
featuring DXT (Deep eXact cutting Technology) achieved by our consistent
pursuit of cutting larger size workpiece but with higher accuracy.
The features and benefits of DXT are:
Deep cutting
3-Stage reduction gear unit and Movable rear blade guard provide larger
capacities of cutting 203mm (8") Crown molding leaning against fence and
Baseboard (Skirt board) which are typical workpieces of slide compound saws.
eXact cutting
Precise and exact cutting obtained by employing:
Double sliding mechanism
Double sliding guide fence
Quick and accurate miter angle lock, etc
LS1216L additionally features laser marker for easy cut line alignment.
