MAINTENANCE
Filing the saw blade
WARNING! Using an incorrect cutting
!attachment or an incorrectly sharpened blade increases the risk of kickback.
•See the cutting attachment packaging for correct sharpening instructions. A correctly filed blade is essential for working efficiently and to avoid unnecessary wear to the blade and clearing saw.
•Make sure that the blade is well supported when you file it. Use a 5.5 mm round file with a file holder.
•The filing angle is 15°. File alternate teeth to the right and those in between to the left. If the blade has been heavily pitted by stones it may be necessary to dress the top edges of the teeth with a flat file, in exceptional cases. If so, this should be done before filing with a round file. The top edges must be filed down by the same amount for all the teeth.
• Adjust the blade setting. This should be 1 mm.
