6.DRILLING WOOD
Be certain workpiece is clamped or anchored firmly. Always apply
pressure in a straight line with the drill bit. Maintain enough pressure to
keep the drill “biting”.
When drilling holes in wood, twist bits can be used. Twist bits may
overheat unless pulled out frequently to clear chips from flutes.
Use a “back-up” block of wood for work that is likely to splinter, such as
thin materials.
You will drill a cleaner hole if you ease up on the pressure just before
the bit breaks through the wood. Then complete the hole from the back
side.
7.DRILLING METaL
There are two rules for drilling hard materials. First, the harder the
material, the greater the pressure you need to apply to the tool.
Second,the harder the material, the slower the speed. Here are a couple
of tips for drilling in metal.
Lubricate the tip of the bit occasionally with cutting oil except when
drilling soft metals such as aluminum, copper or cast iron. If the hole
to be drilled is fairly large, drill a smaller hole first, then enlarge to the
required size. Maintain enough pressure to make sure that the bit does
not just spin in the hole. This will dull the bit and greatly shorten its life.
MaINTENaNCE
WaRNING!
To prevent serious injury from accidental operation
Turn the power switch of the tool to its “OFF” position and unplug
the tool from its electrical outlet before performing any inspection,
maintenance, or cleaning procedures.
Tool service must be performed only by qualified repair personnel.
Service or maintenance performed by unqualified personnel could result
in a risk of injury.
If the tool does not work properly, return the tool to a service facility for
repairs.
Cleaning
Clean out dust and debris from vents and electrical contacts by blowing
with compressed air. Always wear safety goggles when cleaning tools
with compressed air.
Keep tool handles clean, dry and free of oil or grease.
Use only mild soap and a damp cloth to clean the tool, keeping away
from all electrical contacts.
Never use flammable or combustible solvents around tools.
