NOTE: When driving wood screw, pre-drill a pilot hole 2/3 the diameter of the
screw. It makes driving easier and prevents splitting of the workpiece.
Drilling operation
First, turn the action mode changing ring so that the arrow points to the marking. Then proceed as follows.
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 exceptions are iron and brass
which should be drilled dry.
⚠ 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.
MAINTENANCE
⚠ CAUTION: Always be sure that the tool is switched off and the battery
cartridge is removed before attempting to perform inspection or maintenance.
NOTICE: Never use gasoline, benzine, thinner, alcohol or the like.
