SWITCHES
To start Drill, depress trigger switch; to stop Drill, release trigger. To lock trigger
in "ON" position for continuous operation, depress trigger and push up locking
button "A" Figure 1, then gently release trigger. To release locking mech¬
anism, depress trigger fully, then release it. Before using the tool (each time) be
sure that the lock button release mechanism is working freely.
Do not lock the switch "ON" when drilling by hand so that you can instantly re¬
lease the trigger switch if the bit binds in the hole.
Be sure to release the switch locking button before disconnecting the plug from
the power supply. Failure to do so will cause the tool to start immediately the next
time it is plugged in. Damage or injury could result.
The Variable Speed Trigger Switch permits speed control — the farther the trigger
is depressed, thehigher the speed of the Drill. NOTE: Use lower speeds for start¬
ing holes without a center punch, drilling in metal or plastics, driving screws,
drilling ceramics, or mixing paint. Higher speeds are better for drilling wood and
composition boards, and for using abrasive and polishing accessories.
The Reversing Switch is used for withdrawing bits from tight holes and removing
screws at lower speeds. It is located on the back of the handle (Fig. 2). To
reverse the motor, release the trigger FIRST and then push the switch toward
"R'\ After any reversing operations, return switch to forward position by pushing
it toward "F".
DUAL RANGE OPERATION
The 1170-10 Dual Range Holgun® Drill features a shift
lever located on the underside of the gear case. This
shift lever enables you to select the gear reduction
best suited for your job. When the shift lever indicates
"H" (High), facing outward, the gear reduction will
allow the chuck to rotate from 0-2500 RPM. When the
shift lever indicates "L" (Low), the gear reduction will
allow the chuck to rotate from 0-1200 RPM giving the
maximum amount of power (torque) applied at the
chuck. Shifting is accomplished by lifting the shift
lever from slot in casting and rotating 180° around,
returning the lever flat in slot against casting (Fig. 3).
NOTE: When shifting the gears from one reduction to
another, make sure the tool is not running and that
the shift lever is re-engaged in the slot against the
gear case housing after shifting.
