Installing side grip (auxiliary handle)
Screw the side grip on the tool securely.
Installing or removing drill bit
To install the bit, place it in the 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 bit, turn the chuck key counterclockwise in just
one hole, then loosen the chuck by hand.
Depth gauge
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.
OPERATION
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. 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.
