chips, since space between magnet and working surface weakens
the magnetic pull.
CAUTION: DO NOT USE FEED HANDLE TO LIFT UNIT.
CAUTION: After switching to Demag, the magnetic base may
continue to adhere to the work piece due to residual magnetism. A
light blow with the hand will release the base.
WARNING: Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals known to
cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you do
this type of work. To reduce your exposure to these chemicals: work
in a well ventilated area, and work with approved safety equipment,
such as those dust masks that are specially designed to filter out
microscopic particles.

Motor
Your D WALT tool is powered by a D

power supply agrees with the nameplate marking.
Volts 60 Hz or "AC only" means your tool must be operated only with
alternating current and never with direct current.
Voltage decrease of more than 10% will cause loss of power and
overheating. All D WALT tools are factory tested; if this tool does

steel—with zero air gap. Air gap may be defined as the distance
between the magnet core surface and the mounting plate. The two
surfaces will be kept apart by curvature, coats of paint, by surface
irregularities, bolt heads, etc. Holding power is reduced by rough or
uneven surfaces, insufficient thickness of steel or insufficient
mounting area for the magnet base. The magnet rapidly loses its
holding power when this surface irregularity raises the air gap above
1/64"(.4mm). Keep this air gap to a minimum and be sure to smooth
the surface removing any undue projections, chips or other items that
