FIG. 4
Motor
Your D WALT tool is powered by a D WALT-built motor. Be sure your power
E E
supply agrees with the nameplate marking. Volts 50/60 Hz or "AC only"
means your tool must be operated on alternating current and never with
direct current. Voltage decrease of more than 10% will cause loss of power
and overheating. D WALT tools are factory tested; if this tool does not
E
operate, check power supply.
Torque
Torque is the twisting action which the drill imparts to the bit. As the
FIG. 5
drill bit meets resistance in the material being drilled, the motor
responds by adjusting the output torque to meet the requirement up to
the maximum capacity of the motor and gear system.
At any value of drilling torque, there is a reaction force on the drill
which the operator restrains. On the DW124, the operator is grasping
the switch handle near the point of cord entry and the side handle
which is screwed into the gear case. The gripping surfaces of these
two handles are at significant distances from the drill bit thereby giving
FIG. 6
the operator ample control over the tool.
SHIFT
In addition to the optimized handle design, the DW124 contains a slip
SELECTOR
clutch in the low speed range which softens the mechanical shock
imparted to the operator when the large diameter cutters bite into the
work.
Assembling Side Handle
Two threaded bosses as shown in figure 2 are for installation of the
side handle. Install side handle as shown on desired side and tighten
securely by hand. Use of the side handle is recommended when
drilling at the low speed setting. The side handle should always be
used and is especially important when drilling in the low speed
setting.
