Recommendations for Tool Operation
• Large (5/16" to 1/2" [7.9 mm to 12.7 mm]) holes in steel
can be made easier if a pilot hole (5/32" to 3/16" [4 mm
to 4.8 mm]) is drilledfirst.
• When drilling, always apply pressure in a straight line
with the bit, but do not push hard enough to stall the
motor or deflect thebit. A smooth even flow of material
indicates the proper drilling rate.
• If drilling thin material or material that is prone to
splinter, use a wood “back-up” block to prevent damage
to thework piece.

WARNING:
