Important Warnings - Drills
1. Remove the chuck key before drill starts.
2. High reaction torque can be developed in the case of stalling, which can be caused by excessive loads being applied to
the drill bit, by the drill bit snagging on the material being drilled into or by the drill bit breaking through the material being
drilled.
3. In cases where the means to absorb the reaction torque are requested, it is recommended to use a suspension arm
whenever possible. If that is not possible, side handles are recommended for straight-case tools and pistol grip tools. In any
case, it is recommended to use a means to absorb the reaction torque above 4 Nm for straight tools and above 10 Nm for
pistol grip tools.
4. Keep hands away from the rotating chuck and drill bit.

Tools of this class operate on a wide range of air pressure. It is recommended that air pressure of these tools measures 90 PSI at the tool while running free. Higher
pressure and unclean air will shorten the tool’s life because of faster wear and may create a hazardous condition and void the warranty. Water in the air line will
cause damage to the tool. Drain the air tank daily. Clean the air inlet filter screen on at least a weekly schedule. The recommended hookup procedure can be viewed
in the illustration below. The air inlet, used for connecting air supply, has standard 1/4” NPT American Thread. Line pressure should be increased to compensate for
unusually long air hoses (over 25 feet). Minimum hose diameter should be 3/8” I.D. and fittings should have the same inside dimensions.
