Torque Adjustment Collar (Fig. 5)
The torque adjustment collar (A) is clearly
marked with numbers and a drill bit symbol.
The collar should be rotated until the
desired setting is located at the top of the
tool. Locators are provided in the collar to
eliminate the guess work when selecting
fastening torque. The higher the number
on the collar, the higher the torque and the
larger the fastener which can be driven. To
lock the clutch for drilling operations, move
to the drill bit position.
NOTE: When using the Drill/Driver for
drilling holes, be sure that the Torque
Adjusting Collar is set so the figure of the
drill is aligned with the arrow on the top
of the tool. Failure to do this will allow the
clutch to slip while attempting to drill
Dual Range Gearing (Fig. 5)
The dual range feature of your Driver/Drill allows you to shift gears
for greater versatility.
To select the low speed, high torque setting, turn the tool off and
permit to stop. Slide the gear shifter (B) forward (towards the chuck)
(position 1), as shown. To select the high speed, low torque setting,
turn the tool off and permit to stop. Slide the gear shifter back (away
from chuck, position 2).
NOTE: Do not change gears when the tool is running. If you are
having trouble changing gears, make sure that the dual range
gear shifter is either completely pushed forward or completely
pushed back.
