FORWARD/REVERSE SELECTOR
use the forward/reverse selector (3-fIG 1) to change the direction of rotation of the tool.
The forward/reverse selector has three positions: forward, Reverse, and Off (middle).
LED WORK LIGHT
Your tool has a built-in LeD work light (2-fIG 1) to illuminate the work area. When you turn on the tool, the
work light will automatically turn on.
ELECTRIC BRAKE
This tool is equipped with an electric brake, which provides you with another element of control during various
operations. If the tool consistently fails to quickly stop after trigger switch release, have a qualified serviceman
to examine the tool.
SELECTING AND USING SOCKETS
WArNING:
may shatter when used, endangering you or others around you.
WArNING:
disconnected before performing any work on the tool.
WArNING:
impact socket adapters to use impact sockets with drives greater than 1/2".
use only impact duty rated sockets and adaptors and always use the correct size socket for the bolts and
nuts being worked. An incorrect sized socket will result in inaccurate and inconsistent fastening torque and/
or damage to the bolt or nut.
To install the socket, align the socket's square drive base with the impact wrench square drive. Push the
socket onto the tool's drive until it locks into place.
To remove the socket, simply pull it off.
APPLICATION
IMPACTING TECHNIQUE
The tightness achieved when impacting a bolt, nut or screw is proportional to the length of time the impact
action is applied. Avoid excessive impacting of the fastener or workpiece to prevent damage, especially
when working with smaller fasteners.
Practice with different fasteners and applications to become familiar with the impacting requirements of
each type. When making these practice runs, make a note of how long each was impacted. Then measure
the tightness of each fastener with a hand torque wrench, then compare the time and tightness information
to help you judge how long to impact various fasteners to achieved a desired torque. If the fasteners are
too tight, reduce impacting time. If they are too loose, increase the impacting time. Repeat the practice
procedure with new fasteners until you can determine the amount of impacting time required to achieve the
desired tightness.
A 3/8" bolt generally requires two seconds of impacting time, while a 5/16" bolt will require only one second.
However, any contamination on the bolt or under the bolt head will affect impacting time. Additionally,
fasteners of the same diameters but with different lengths will require different impacting times to achieve
the same degree of tightness.
On work where correct torque is critical or a gasket is involved, it is best to tighten down each fastener
lightly and then complete the tightening process with an accurate hand torque wrench.
"BREAKING LOOSE" FASTENERS
This procedure may be used cautiously to remove the occasional fastener that has become "frozen", usually
due to corrosion. Additionally, this procedure assumes that the fastener uses standard threads (clockwise to
tighten, counter-clockwise to loosen).
1. Spray the frozen fastener with penetrating oil designed to dissolve the corrosion causing the nut and/or bolt
Use only sockets rated for IMPACT DUTY. Other types of sockets
Always be sure that the tool is switched off and the battery is
