2. For
reverse
(counterclockwise) rotation, push the
control switch in the direction shown.
Check the
direction of rotation before use.
3. To
lock
the trigger, push the control switch to the
center position. The trigger will not work when the
control switch is in the locked position.
Always remove the battery pack before performing
maintenance or changing accessories. Always
lock the trigger or remove the battery pack before
storing the tool and any time the tool is not in use.
Selecting Speed
Allow the tool to come to a complete stop before
changing speeds. Press the selector button

screws
in sheet metal
IPM 0 - 1200 0 - 3400 0 - 4300
The
function is designed to reduce screw strip-
ping, screw breakage, and damage to the work sur-
face when driving self-tapping screws. This function
is optimized for the most common materials, including
#8, #10 and #12 self-tapping screws between 1/2"-1"
in length and 18-22 gauge sheet metal.
NOTE:
mode will only run if the trigger is pulled
more than half-way. If pulled less than half-way, the
driver will run in the normal impacting mode. When
using the
mode, the tool will shut off automatically
once the screw is fully seated.
Starting, Stopping and Controlling Speed
These tools may be operated at any speed from 0
to full speed.
1. To
start
the tool, pull the trigger.
NOTE:
An LED is turned on when the trigger is pulled.
2. To
vary
the driving speed, increase or decrease
pressure on the trigger. The further the trigger is
pulled, the greater the speed, up to the maximum
speed set by the speed control.
3. To
stop
the tool, release the trigger and the electric
brake stops the tool instantly.
Impacting Techniques
The longer a bolt, screw, or nut is impacted, the
tighter it will become. To help prevent damaging the
fasteners or workpieces, avoid excessive impact-
ing. Be particularly careful when impacting smaller
fasteners because they require less impacting to
reach optimum torque.
Practice with various fasteners, noting the length of
time required to reach the desired torque. Check the
tightness with a hand-torque wrench. If the fasteners
are too tight, reduce the impacting time. If they are
not tight enough, increase the impacting time.
Oil, dirt, rust or other matter on the threads or under
the head of the fastener affects the degree of tight
-
ness.
The torque required to loosen a fastener averages
75% to 80% of the tightening torque, depending on
the condition of the contacting surfaces.
On light gasket jobs, run each fastener down to a
relatively light torque and use a hand torque wrench
for final tightening.
