Selecting the action mode
CAUTION:
Always slide the action mode chang-
ing lever all the way to your desired mode position.
If you operate the tool with the lever positioned halfway
between the mode symbols, the tool may be damaged.
► Fig.4: 1. Action mode changing lever
This tool has an action mode changing lever. For rota-
tion with hammering, slide the action mode changing
lever to the right ( symbol). For rotation only, slide the
action mode changing lever to the left ( symbol).
ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and unplugged before carrying out
any work on the tool.
Installing side grip (auxiliary handle)
CAUTION:
Always be sure that the tool is
switched off and unplugged before installing or
removing the side grip.
► Fig.5: 1. Grip base 2. Teeth 3. Side grip (auxiliary
handle) 4. Protrusion 5. Loosen 6. Tighten
Always use the side grip to ensure operating safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on the tool barrel. Then tighten
the grip by turning clockwise at the desired position. It
may be swung 360° so as to be secured at any position.
NOTE: The side grip cannot swing 360° when the
depth gauge is installed.
Installing or removing drill bit
CAUTION:
Always be sure that the tool is
switched off and unplugged before installing or
removing the drill bit.
For model HP1640
► Fig.6: 1. Drill chuck 2. Chuck key
To install the drill bit, place it in the drill chuck as far as
it will go. Tighten the chuck by hand. Place the chuck
key in each of the three holes and tighten clockwise. Be
sure to tighten all three chuck holes evenly.
To remove the drill bit, turn the drill chuck key counter-
clockwise in just one hole, then loosen the chuck by hand.
After using the chuck key, be sure to return it to the original position.
For model HP1641, HP1641F
► Fig.7: 1. Sleeve 2. Ring
Hold the ring and turn the sleeve counterclockwise to open the chuck
jaws. Place the drill bit in the drill chuck as far as it will go. Hold the
ring firmly and turn the sleeve clockwise to tighten the chuck.
To remove the drill bit, hold the ring and turn the sleeve
counterclockwise.
Depth gauge
► Fig.8: 1. Depth gauge 2. Side grip 3. Grip base
The depth gauge is convenient for drilling holes of
uniform depth. Loosen the side grip and insert the depth
gauge into the hole in the grip base. Adjust the depth
gauge to the desired depth and tighten the side grip
firmly.
NOTE: Make sure that the depth gauge does not
touch the main body of the tool when attaching it.
OPERATION
CAUTION:
Always use the side grip (auxiliary
handle) and firmly hold the tool by both side grip
and switch handle during operations.
► Fig.9
Hammer drilling operation
CAUTION:
There is tremendous and sudden
twisting force exerted on the tool/drill 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. Always use the side
grip (auxiliary handle) and firmly hold the tool by
both side grip and switch handle during opera-
tions. Failure to do so may result in the loss of control
of the tool and potentially severe injury.
When drilling in concrete, granite, tile, etc., move the
action mode changing lever to the position of
to use "rotation with hammering" action.
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
Optional accessory
► Fig.10: 1. Blow-out bulb
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
