Ø
DO NOT use this machine without safely securing to the work piece being drilled.
Ø
DO NOT use full water pressure when drilling with “wet” type bits! You need minimal water to
drill with these machines. Extreme water pressure can cause water to enter the gearbox!
Ø
DO NOT operate this machine on a lower voltage as it may result in reduced power level and
the machine could become unstable while cutting. This could also limit the motor life.
o
NOTE: Use of long small gauge power extension cords can result in decreased
voltage. As local voltages can vary, it may be a good idea to test the voltage at the
end of the extension cord to ensure proper voltage requirements are met. You might
also consult an electrician to make sure the length of cord matches up with the proper
wire gauge for this size motor. Make sure to use outdoor cords when operating
outdoors.
HEALTH WARNINGS
Ø
Certain dust created by drilling contains chemicals known to cause cancer, birth defects or
other reproductive harm. The examples of these chemicals are below:
o
Lead from lead based paint.
o
Crystalline silica from bricks, cement and assorted masonry products.
§
TO REDUCE RISK OF EXPOSURE TO THESE CHEMICALS, WORK IN A WELL
VENTILATED AREA WITH VACUUM SYSTEMS, RESPIRATORS AND WITH
ALL SUITABLE SAFETY EQUIPMENT.
