7. Mounting drill bits (Fig. 2)
Tighten drill bits with the chuck wrench.
There are three holes in which the chuck
wrench should be inserted. Tighten them
equally in turn at three holes, without
tightening them only at one hole. The drill bit
can be removed in the opposite method as
mentioned above.
8. Confirm the direction of bit rotation
(Fig. 3)
The bit rotates clockwise (viewed from the
top side) by pushing the R-side of the
reversing switch lever. The L-side of the lever
is pushed to turn the bit counterclockwise.
CAUTION
Never change the direction of bit rotation
while operating.
Turn the power switch OFF before changing
the direction of bit rotation; otherwise,
burning of the motor will result.
9. Fixing the side handle
Screw the side handle into the gear cover.
HOW TO USE
CAUTION:
To prevent accidents, make sure to turn the
switch off and disconnect the plug from the
receptacle when the drill bits and other
various parts are installed or removed. The
power switch should also be turned off during
a work break and after work.
1. Operation of switch
⅜ Turning the switch on
