Installing side grip (auxiliary handle)
(Fig. 8)
CAUTION:
• Always use the side grip to ensure operating safety
when drilling in concrete, masonry, etc.
The side grip swings around to either side, allowing easy
handling of the tool in any position. Loosen the side grip
by turning it counterclockwise, swing it to the desired
position and then tighten it by turning clockwise.
Installing or removing the bit (Fig. 9)
Clean the bit shank and apply bit grease before installing
the bit.
Insert the bit into the tool. Turn the bit and push it in until it
engages. (Fig. 10)
If the bit cannot be pushed in, remove the bit. Pull the
chuck cover down a couple of times. Then insert the bit
again. 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.
To remove the bit, pull the chuck cover down all the way
and pull the bit out. (Fig. 11)
Bit angle (when chipping, scaling or
demolishing) (Fig. 12)
The bit can be secured at 24 different angles. To change
the bit angle, depress the lock button and rotate the
change lever so that the pointer points to the
Turn the bit to the desired angle.
Depress the lock button and rotate the change lever so
that the pointer points to the
that the bit is securely held in place by turning it slightly.
Depth gauge (Fig. 13)
The depth gauge is convenient for drilling holes of uniform
depth. Loosen the clamp screw and adjust the depth
gauge to the desired depth. After adjusting, tighten the
clamp screw firmly.
NOTE:
• The depth gauge cannot be used at the position where
the depth gauge strikes against the gear housing/motor
housing.
OPERATION
CAUTION:
• Always use the side grip (auxiliary handle) and firmly
hold the tool by both side grip and switch handle during
operations.
Hammer drilling operation (Fig. 14)
Set the change lever to the
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.

symbol.
CAUTION:
• When the bit begins to break through concrete or if the
bit strikes reinforcing rods embedded in concrete, the
tool may react dangerously. Maintain good balance
and safe footing while holding the tool firmly with both
hands to prevent dangerous reaction.
Blow-out bulb (optional accessory)
(Fig. 15)
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Chipping/Scaling/Demolition (Fig. 16)
Set the change lever to the
Hold the tool firmly with both hands. Turn the tool on and
apply slight pressure on the tool so that the tool will not
bounce around, uncontrolled. Pressing very hard on the
tool will not increase the efficiency.
Drilling in wood or metal (Fig. 17)
Use the optional keyless drill chuck assembly. When
installing it, refer to "Installing or removing the bit"
described on the previous page.
Set the change lever so that the pointer points to the
symbol.
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far as it
will go. Hold the ring firmly and turn the sleeve clockwise
to tighten the chuck. To remove the bit, hold the ring and
turn the sleeve counterclockwise.
CAUTION:
• Never use "rotation with hammering" when the quick
change drill chuck is installed on the tool.
The quick change drill chuck may be damaged.
• 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 twisting force exerted on the
tool/bit at the time of hole breakthrough. Hold the tool
firmly and exert care when the bit begins to break
through the workpiece.
• Always secure small workpieces in a vise or similar
hold-down device.
Diamond core drilling
When performing diamond core drilling operations,
always set the change lever to the
"rotation only" action.
CAUTION:
• If performing diamond core drilling operations using
"rotation with hammering" action, the diamond core bit
may be damaged.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
