Hold the tool firmly with one hand on the grip and the other hand on the
bottom of the battery cartridge to control the twisting action
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 action mode changing ring so that the arrow on the tool body points to the marking. The adjusting ring can be aligned in any torque levels for this operation. 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
After drilling the hole, use the blow-out bulb to clean the dust out of the hole.
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.
Discoloration, deformation or cracks may result.
