8.
Reduce the pressure on the drill just before the bit cuts through the work
to avoid splintering wood or stalling in metal.
9.
When bit has completely penetrated work and is spinning freely,
withdraw it from the work while the motor is still running, then turn off drill.
DRILLING WOOD
WARNING: SOME WOOD CONTAINS PRESERVATIVES WHICH
CAN BE TOXIC. Take extra care to prevent inhalation and skin
contact when working with these materials. Request, and follow, any
safety information available from your material supplier.
In addition to the instructions listed under GENERAL DRlLLlNG, the following
also apply:
1.
When using twist drills in wood, they should be withdrawn from the hole
frequently to clear chips built up in flutes to avoid overheating and burning
work.
2.
If a backing block is used to keep back of work from splintering, it
should be clamped securely in place. If a backing block is not used with
spade bits or auger bits, ease up pressure as soon as bit point breaks
through work, and complete the hole from the opposite side.
DRILLING METAL
In addition to the instructions listed under GENERAL DRlLLlNG, the following
also apply:
CAUTlON: When drilling metal, jamming of bit is more likely than
when drilling other materials.
1.
Use only good quality sharp high speed steel twist bits when drilling
metal.
2.
Start drilling with slow speed and gradually increase speed as drill cuts.
The harder the material, the slower the speed required. The softer the
material, the faster the speed.
3.
When drilling a large hole, it is easier to first drill a smaller hole and then
enlarge it to the required size.
4.
The use of a lubricant, such as oil, on the drill point helps keep the bit
cool, increases drilling action and prolongs drill bit life.
KEEP TOOL CLEAN
Periodically blow out all air passages with dry compressed air. All plastic
parts should be cleaned with a soft damp cloth. NEVER use solvents to clean
plastic parts. They could possibly dissolve or otherwise damage the material.
CAUTION: Wear safety glasses while using compressed air.
FAILURE TO START
Should your tool fail to start, check to make sure the prongs on the cord plug
are making good contact in the outlet. Also, check for blown fuses or open
circuit breakers in the line.
