RIDGID R842301 Operator's Manual page 8

OPERATION
 Make sure the latches on each side of the battery pack
snap into place and the battery pack is secured to the
impact driver before beginning operation.
CAUTION:
When placing battery pack in the tool, be sure
raised rib on battery pack aligns with the bottom
of the impact driver and latches into place properly.
Improper installation of the battery pack can cause
damage to internal components.
TO REMOVE BATTERY PACK
See Figure 2, page 11.
 Locate the latches on the side of the battery pack and
depress both sides to release the battery pack from the
impact driver.
 Remove the battery pack.
WARNING:
Battery tools are always in operating condition.
Therefore, switch should always be locked when
not in use or carrying at your side.
SWITCH TRIGGER
See Figure 3, page 11.
To turn the impact driver ON, depress the switch trigger. To
turn it OFF, release the switch trigger.
VARIABLE SPEED
See Figure 3, page 11.
This tool has a variable speed switch that delivers higher
speed with increased trigger pressure. Speed is controlled
by the amount of switch trigger depression.
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.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 3, page 11.
The direction of bit rotation is reversible and is controlled by
a selector located above the switch trigger. With the impact
driver held in normal operating position, the direction of rota-
tion selector should be positioned to the left of the switch
trigger for driving. The driving direction is reversed when the
selector is to the right of the switch trigger.
Setting the switch trigger 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 coupler
to come to a complete stop before changing the
direction of rotation.
To stop the impact driver, release the switch trigger and allow
the coupler to come to a complete stop.
NOTE: The impact driver will not run unless the direction of
rotation selector is pushed fully to the left or right.
Avoid running the driver at low speeds for extended
periods of time. Running at low speeds under constant
usage may cause the driver to become overheated. If this
occurs, cool the driver by running it without a load and at
full speed.
INSTALLING BITS
See Figure 4, page 11.
 Lock the switch trigger by placing the direction of
rotation selector in the center position.
 Remove the battery pack from the impact driver.
 Pull the coupler away from the driver (1).
 Insert driver bit to be used into the coupler (2).
 Release the coupler (3).
 Pull on the bit to make sure it is secured in the coupler.
There may be some play in the installed bit; this is
normal.
NOTE: Use only impact quality bits with a locking
groove.
WARNING:
Make sure the bit is secured in the coupler before
using the impact driver. Failure to do so could
cause serious personal injury.
REMOVING BITS
See Figure 4, page 11.
 Lock the switch trigger by placing the direction of
rotation selector in the center position.
 Remove the battery pack from the impact driver.
 Pull the coupler away from the driver.
 Remove driver bit from the coupler.
WARNING:
Do not drive a screw where there is likely to be
hidden wiring behind the surface. Contact with a
"live" wire will make exposed metal parts of the tool
"live" and shock the operator. If you must drive a
screw where hidden wire may be present, always
hold tool by insulated gripping surfaces (handle)
when performing the operation to prevent a shock
to the operator, as seen in figure 5.
CAUTION:
The impact driver is not designed to be used as
a drill.
