OPERATION

Fig.9
CAUTION:
Always insert the battery cartridge all the way until it
•
locks in place. Otherwise, it may accidentally fall
out of the tool, causing injury to you or someone
around you.
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.
CAUTION:
Do not cover vents, or it may cause overheating
•
and damage to the tool.
Hammer drilling operation
CAUTION:
There is a tremendous and sudden twisting force
•
exerted on the tool/bit at the time of hole
break-through, 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
ring can be aligned in any torque levels for this operation.
Be sure to use a tungsten-carbide tipped bit.
Position the 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 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.10
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Drilling operation
First, turn the adjusting ring so that the pointer points to
the marking. Then proceed as follows.
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 bit, decrease the tool
performance and shorten the service life of the tool.
There is a tremendous force exerted on the tool/bit
•
at the time of hole break through. Hold the tool
firmly and exert care when the bit begins to break
through the workpiece.
A stuck 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
marking. The adjusting
do not hold it firmly.
Always secure small workpieces in a vise or with a
•
similar hold-down device.
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.
Do not pull the switch trigger repeatedly when the
•
motor is locked. It may damage the tool.
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 bit into the workpiece.
Drilling in metal
To prevent the bit from slipping when starting to make a
hole, make an indentation with a center-punch and
hammer at the point to be drilled. Place the point of the
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.
Screwdriving operation
First, turn the action mode changing ring so that the
arrow on the tool body points to the
the adjusting ring to the proper torque level for your work.
Then proceed as follows.
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the clutch cuts in.
CAUTION:
Make sure that the driver bit is inserted straight in
•
the screw head, or the screw and/or bit may be
damaged.
NOTE:
When driving wood screw, predrill a pilot hole 2/3
•
the diameter of the screw. It makes driving easier
and prevents splitting of the workpiece.
Using the tool as a hand screwdriver
Fig.11
Switch off the tool.
Move the reversing switch lever to the neutral position.
Turn the tool.
NOTE:
This use is convenient for checking the screwdriving.
•
Do not use the tool for work requiring excessive
•
force, such as tightening bolt or removing rusted
screws.
Using holster (optional accessory)
CAUTION:
Do not use for tools such as a drill with a bit
•
installed on them.
Turn off the tool and wait until it comes to a
•
complete stop before placing it in the holster.
