CAUTION:
•
If the tool is operated continuously at low speeds
for a long time, the motor will get overloaded,
resulting in tool malfunction.
•
The speed adjusting dial can be turned only as far
as 5 and back to 1. Do not force it past 5 or 1, or the
speed adjusting function may no longer work.
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)

007796
For maximum control and safer operation, always use
the side grip with this tool. 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.
Bit grease (optional accessory)
Coat the bit shank head beforehand with a small amount
of bit grease (about 0.5 -1 g; 0.02 - 0.04 oz.). This chuck
lubrication assures smooth action and longer service life.
Installing or removing the bit
Press in the tool retainer and turn it until the red dots on
the tool retainer and the tool holder are aligned. Release
the tool retainer.

uniform depth. Insert the depth gauge into the hole in the
grip base. Adjust the depth gauge to the desired depth
and then tighten the clamp screw to secure the depth
gauge.
NOTE:
•
The depth gauge cannot be used at the position
where the depth gauge strikes against the tool
body.
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
