DRILLING
– cont’d
When drilling metals, use a light oil on the
drill bit to keep it from overheating. The oil
will prolong the life of the drill bit and
improve the drill cutting action. If the bit
jams in the workpiece or if the tool stalls,
release the trigger switch immediately.
Remove the bit from the workpiece and
determine the reason for jamming
DRILLING IN CONCRETE
WARNING:
Always use a face
shield when drilling in concrete.
Always use the hammer mode and
slower
drill speeds for faster drilling in concrete.
Always use carbide tipped masonry bits.
WARNING:
When servicing, use
only identical replacement parts. Use of
any other part may create a hazard or
cause product damage.
DO NOT use solvents when cleaning
plastic parts. Plastics are susceptible to
damage from various types of commercial
solvents and may be damaged by their
use. Use a clean cloth to remove dirt, dust,
oil, grease etc.
WARNING:
Do not at any time
allow brake fluids, gasoline, petroleum-
based products, penetrating oils, etc. to
come into contact with plastic parts.
They contain chemicals that can
damage, weaken or destroy plastic.
DO NOT abuse power tools. Abusive
practices can damage the tool as well as
the workpiece.
WARNING:
DO NOT attempt to
modify tools or create accessories. Any
such alteration or modification is
misuse and could result in a hazardous
condition leading to possible serious
injury. It will also void the warranty.
