Hammer drilling operation
Set the action mode changing knob to the symbol.
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 slip-
ping 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 sev-
eral times, the hole will be cleaned out and normal drilling
may be resumed.
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. Always use the side grip (auxiliary handle)
and firmly hold the tool by both side grip and switch
handle during operations. Failure to do so may result in
the loss of control of the tool and potentially severe
injury.
Blow-out bulb (optional accessory)
After drilling the hole, use the blow-out bulb to clean the dust
out of the hole.
Drilling in wood or metal
Use the optional drill chuck assembly. When installing it, refer
to “Installing or removing the bit” described on the previous
page.
Set the action mode changing knob to “rotation only”.
You can drill up to 13 mm (1/2”) diameter in metal and up to
32 mm (1 - 1/4”) diameter in wood.
