general Operating instructions
1. Before plugging in the Power Cord
(112), insert the desired Bit. Adjust
the Auxiliary Handle (107) and Depth
Gauge (106) to the desired positions.
Then adjust the Switching Knob
(24) and Selector (91) to the desired
positions. (See Figure A.)
2. Make sure the Power Switch (96) is
in its "OFF" position. Then plug the
Power Cord (112) into the nearest
110 volt, grounded, electrical outlet.
(See Figure A.)
3. When ready to use the Rotary
Hammer, squeeze the Power Switch
(96) and allow the tool to run without
load for about one minute. This
allows the tool's parts to become
properly lubricated. Check to see
if the running tool sounds normal.
Once the tool has been warmed up, it
is ready for use. (See Figure A.)
4. When finished using the Rotary
Hammer, release the Power Switch
(96). Wait until the tool comes to a
complete stop. Then unplug the tool
from its electrical outlet. (See Figure
A.)
5. Make sure the Drill Bit is completely
cooled. Then remove the Bit from
the tool.
