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:

• Do not use this tool to mix or pump easily

combustible or explosive fluids (benzine,

alcohol,etc.).

• Do not mix or stir inflammable liquids

labelledaccordingly.
