FUNCTIONAL DESCRIPTION

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before adjusting or checking function on
the tool.
Switch action
Fig.1
CAUTION:
Before plugging in the tool, always check to see
•
that the switch trigger actuates properly and
returns to the "OFF" position when released.
Switch can be locked in "ON" position for ease of
•
operator comfort during extended use. Apply
caution when locking tool in "ON" position and
maintain firm grasp on tool.
To start the tool, simply pull the switch trigger. Tool
speed is increased by increasing pressure on the switch
trigger. Release the switch trigger to stop. For
continuous operation, pull the switch trigger, push in the
lock button and then release the switch trigger. To stop
the tool from the locked position, pull the switch trigger
fully, then release it.
Reversing switch action

CAUTION:
Always check the direction of rotation before
•
operation.
Use the reversing switch only after the tool comes
•
to a complete stop. Changing the direction of
rotation before the tool stops may damage the tool.
If the switch trigger can not be depressed, check to

symbol on the tool
Use the knob after the tool comes to a complete
•
stop.
Torque limiter
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output shaft. When this happens, the bit will stop turning.
CAUTION:
As soon as the torque limiter actuates, switch off
•
the tool immediately. This will help prevent
premature wear of the tool.
Bits such as hole saw, which tend to pinch or catch
•
easily in the hole, are not appropriate for this tool.
This is because they will cause the torque limiter to
actuate too frequently.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before carrying out any work on the tool.
Side grip (auxiliary handle)
Fig.4
CAUTION:
Always use the side grip to ensure operating safety.
•
Install the side grip so that the protrusions on the grip fit
in between the grooves on the tool barrel. Then tighten
the thumb screw to fix the grip at the desired position. It
may be swung 360° so as to be secured at any position.
Bit grease
Coat the bit shank head beforehand with a small amount
of bit grease (about 0.5 - 1 g).
This chuck lubrication assures smooth action and longer
service life.
Installing or removing the bit
Fig.5
Clean the bit shank and apply bit grease before installing
the bit.
Fig.6
Insert the bit into the tool. Turn the bit and push it in until
it engages.
After installing, always make sure that the bit is securely
held in place by trying to pull it out.
Fig.7
To remove the bit, pull the chuck cover down all the way
and pull the bit out.
Depth gauge
Fig.8
The depth gauge is convenient for drilling holes of
uniform depth. Loosen the thumb screw and adjust the
depth gauge to the desired depth. After adjusting,
tighten the thumb screw firmly.
