SAWING METAL
When cutting angle, H-beam, I-beam, channel, etc., start the cut on the
surface where the greatest number of teeth will contact the work. To make a
pocket cut, drill a starting hole first. To extend blade life, cutting oil can be
applied to the work surface along the line of the cut.

KEEP TOOL CLEAN
Periodically blow out all air passages with dry compressed air. All plastic parts

parts. They could possibly dissolve or otherwise damage the material.
Wear ANSI Z87.1 safety glasses while using compressed air.
FAILURE TO START
Should your tool fail to start, check to make sure the prongs on the cord plug are
making good contact in the outlet. Also, check for blown fuses or open circuit
breakers in the line.
