Ryobi CDD18V2 Owner's Operating Manual page 8

Battery products are always in operating
condition. Therefore, the switch should always
be locked when not in use or when carried at
your side.
SWITCH TRIGGER
See Figure 3.
To turn the drill ON, depress the switch trigger. To turn it
OFF, release the switch trigger.
VARIABLE SPEED
The switch trigger delivers higher speed and torque
with increased trigger pressure and lower speed with
decreased trigger pressure.
NOTE: You might hear a whistling or ringing noise from
the switch during use. Do not be concerned; this is a
normal part of the switch function.
ROTATION SELECTOR (FORWARD/REVERSE/
CENTER LOCK)
See Figure 3.
The direction of bit rotation is reversible and is controlled
by a selector located above the switch trigger. With
the drill held in normal operating position, the rotation
selector should be positioned to the left of the switch
trigger for drilling. The drilling direction is reversed when
the selector is to the right of the switch trigger.
Setting the rotation selector in the OFF (center lock)
position helps reduce the possibility of accidental starting
when not in use.
CAUTION:
To prevent gear damage, always allow the chuck
to come to a complete stop before changing the
direction of rotation.
To stop the drill, release the switch trigger and allow the
chuck to come to a complete stop.
NOTE: The drill will not run unless the rotation selector is
pushed fully to the left or right.
Avoid running the drill at low speeds for extended
periods of time. Running at low speeds under constant
usage may cause the drill to become overheated. If this
occurs, cool the drill by running it without a load and at
full speed.
KEYLESS CHUCK
See Figure 3.
The drill has a keyless chuck to tighten or release drill
bits in the chuck jaws. Grasp and hold the collar of the
chuck with one hand. Rotate the chuck body with your
English
other hand. The arrows on the chuck indicate which
direction to rotate the chuck body in order to LOCK
(tighten) or UNLOCK (release) the drill bit.
WARNING:
Do not hold the chuck body with one hand and
use the power of the drill to tighten the chuck
jaws on the drill bit. The chuck body could slip in
your hand, or your hand could slip and come in
contact with the rotating drill bit. This could cause
an accident resulting in serious personal injury.
TWO-SPEED GEAR SWITCH
See Figure 4.
The drill has a two-speed gear switch designed for
drilling or driving at LO (1) or HI (2) speeds. A slide
switch is located on top of the drill to select either LO
(1) or HI (2) speed. When using drill in the LO (1) speed
range, speed will decrease and unit will have more
power and torque. When using drill in the HI (2) speed
range, speed will increase and unit will have less power
and torque. Use LO (1) speed for high power and torque
applications and HI (2) speed for fast drilling or driving
applications.
ADJUSTABLE TORQUE CLUTCH
This product is equipped with an adjustable torque
clutch for driving different types of screws into different
materials. The proper setting depends on the type of
material and the size of screw you are using.
ADJUSTING TORQUE
There are twenty-four torque indicator settings located
on the front of the drill.
■ Rotate adjustment ring to the desired setting.
• 1 - 4 For driving small screws
• 5 - 8 For driving screws into soft material
• 9 - 12 For driving screws into soft and hard materials
• 13 - 16 For driving screws in hard wood
• 17 - 20 For driving large screws
• 21 - For heavy drilling
INSTALLING BITS
■ Lock the switch trigger by placing the rotation selector
in the center position.
■ Open or close the chuck jaws to a point where the
opening is slightly larger than the bit size you intend to
use. Also, raise the front of the drill slightly to keep the
bit from falling out of the chuck jaws.
