ADJUSTING TORQUE COLLAR
The clutch unit provides twenty clutch
settings plus a “Drill” (solid-lockup)
setting. Lowest torque is avaible at setting
#1, with maximum torque available at the
“Drill” setting. The amount of output
torque may be adjusted by rotating the
front collar (A) Fig. 3, so that the desired
torque setting is aligned with the index
mark (B) Fig. 3. In general, lower torque
settings are used for driving small screws
and other delicate work, while higher
torque settings are used for driving larger
screws. The “Drill” position is used for
drilling and for driving very large screws.
TWO-SPEED GEAR SHIFT
The Model 884 Cordless Driver/Drill has
a two-speed gear shift which provides
spindle speed ranges of approximately:
0 to 450 RPM (LOW) and 0 to 1450 RPM
(HIGH). To change speed ranges: release
trigger switch to stop motor and then
slide speed selector (A) Fig. 4, toward
rear for HIGH speed or toward front for
LOW speed.
The low speed position is normally used
when drilling larger holes and when
driving or removing screws. The high
speed position is normally used for
drilling small holes.
DRIVER BIT STORAGE
Convenient storage areas with retaining clip (B) Fig. 4, for screwdriver bits are
provided on each side of the tool.
