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.
