OPERATION
R86039 IMPACT DRIVER
INSTALLING / REMOVING BITS
See Figure 4, page 15.
 To install bits, remove the battery pack from the tool.
 Push the bit into the coupler until it clicks into place.
NOTE: If the bit does not insert easily into the coupler,
pull the coupler forward and reinsert the bit.
 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.
 To remove bits, remove the battery pack from the tool.
 With the nose of the tool pointed away from you, pull the
coupler away from the driver.
 The bit will eject from the coupler.
 The bit provided with the tool can be placed in the storage
area, located on the rear base of the tool.
SPEED / TORQUE SELECTOR
See Figure 5, page 15.
The speed selector toggle button allows speed adjustments
from high speed, medium speed and low speed. Each press
of the speed toggle button will lower speed from HIGH to
MEDIUM and then to LOW. When pressed again, the speed
will change back to HIGH.
NOTE: The speed can only be changed in this sequence.
 HIGH (3) Speed/Torque (0-3000 RPM/high torque)
 MEDIUM (2) Speed/Torque (0-2200 RPM/medium torque)
 LOW (1) Speed/Torque (0-750 RPM/low torque)
NOTICE:
Never change speeds or modes while the tool is
running. Failure to obey this caution could result
in serious damage to the tool.
MODE SELECTOR
See Figure 5, page 15.
The mode selector toggle button allows mode adjustments.
Each press of the mode toggle button changes the modes
from Self-Drilling Screw Mode, Fastener Assist Mode and
Auto Stop Mode in that order.
Self-Drilling Screw Mode:
The Self-Drilling Screw Mode function is designed to reduce
screw stripping, screw breakage, and damage to work sur-
faces when driving self-drilling screws.
 When driving fasteners (forward setting), the impact driver
will start fast to drive the fastener through the workpiece
and then slow the speed to finish.
NOTE: In the reverse setting, the impact driver will resume
normal operation.
Fastener Assist Mode:
The forward setting of Fastener Assist Mode is designed to
help drive troublesome fasteners into materials easily.
 When driving fasteners (forward setting), the impact driver
will start slow to drive the fastener into the workpiece and
then speed up to finish.
The reverse setting of Fastener Assist Mode is designed to
help remove troublesome/stripped fasteners without causing
additional damage to the driving bit or fastener.
 When removing fasteners (reverse setting) the impact
driver will pulse six times and then speed up to remove
the fastener.
