Recommendations for Tool Operation
• 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 workpiece.

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.
