Hammer drilling operation
CAUTION:
There is a tremendous and sudden
twisting force exerted on the tool/drill bit at the
time of hole breakthrough, when the hole becomes
clogged with chips and particles, or when striking
reinforcing rods embedded in the concrete.
First, turn the adjusting ring so that the arrow on the tool
body points to the
marking.
Be sure to use a tungsten-carbide tipped drill bit.
Position the drill bit at the desired location for the hole,
then pull the switch trigger. Do not force the tool. Light
pressure gives best results. Keep the tool in position
and prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes clogged with
chips or particles. Instead, run the tool at an idle, then remove the
drill bit partially from the hole. By repeating this several times, the
hole will be cleaned out and normal drilling may be resumed.
Blow-out bulb
Optional accessory
Fig.17
► 1 . Blow-out bulb
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Drilling operation
CAUTION:
Pressing excessively on the tool
will not speed up the drilling. In fact, this excessive
pressure will only serve to damage the tip of your drill
bit, decrease the tool performance and shorten the
service life of the tool.
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it firmly.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
CAUTION:
If the tool is operated continuously
until the battery cartridge has discharged, allow
the tool to rest for 15 minutes before proceeding
with a fresh battery.
First, turn the adjusting ring so that the arrow points to
the
Drilling in wood
When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide screw
makes drilling easier by pulling the drill bit into the workpiece.
Drilling in metal
To prevent the drill bit from slipping when starting a
hole, make an indentation with a center-punch and
hammer at the point to be drilled. Place the point of the
drill bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep-
tions are iron and brass which should be drilled dry.
MAINTENANCE
CAUTION:
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
NOTICE:
alcohol or the like. Discoloration, deformation or
cracks may result.
