Dual Range Gearing (Fig.A)
The dual range feature of your drill/driver allows you to shift
gears for greaterversatility.
1. To select speed 1(high torque setting), turn the tool off
and permit it to stop. Slide the gear shifter
4
forward (towards
thechuck).
Torque Adjustment Collar (Fig.A)
Your tool has an adjustable torque screwdriver mechanism for
driving and removing a wide array of fastener shapes and sizes
and in some models, a hammer mechanism for drilling into
masonry. Circling the torque adjustment collar
3
are numbers,
a drill bit symbol, and on some models, a hammer symbol.
These numbers are used to set the clutch to deliver a torque
range. The higher the number on the collar, the higher the
torque and the larger the fastener which can be driven. To select
any of the numbers, rotate until the desired number aligns with
thearrow.
Forward/Reverse Control Button (Fig.A)
A forward/reverse control button
2
determines the direction of
the tool and also serves as a lock-offbutton.
To select forward rotation, release the trigger switch and
depress the for ward/re verse control button on the right side of
thetool.
To select reverse, release the trigger switch and depress the
forward/reverse control button on the left side of thetool.
The centre position of the control button locks the tool in the off
position. When changing the position of the control button, be
sure the trigger isreleased.
NOTE: The first time the tool is run after changing the direction
of rotation, you may hear a click on start up. This is normal and
does not indicate aproblem.
Variable Speed Trigger Switch (Fig.A)
To turn the tool on, squeeze the variable speed
triggerswitch
1
. To turn the tool off, release the trigger switch.
Your tool is equipped with a brake. The chuck will stop as soon
as the trigger switch is fullyreleased.
NOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should
beavoided.
