tool in the off position. When changing the position of the
control button, be sure the trigger is released.
nOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should
be avoided.
nOTE: The first time the tool is run after changing the
direction of rotation, you may hear a click on start up. This is
normal and does not indicate a problem.
Worklight (Fig. A)
The worklight

is activated when the trigger switch is
depressed, and will automatically turn off 20 seconds after
the trigger switch is released. If the trigger switch remains
depressed, the worklight will remain on.
nOTE: The worklight is for lighting the immediate work
surface and is not intended to be used as a flashlight.
Mode Selector (Fig. A, G)
Your tool is equipped with a mode selector
you to select one of two speeds or the Impact Assist mode.

Impact Assist™ (Fig. G)
In addition to normal impacting modes, this tool features the
Impact Assist™ mode which grants the user greater control
in both fastening and loosening applications. When set in
forward, the tool will fasten at 2000 RPM until impact begins.
The tool will then pause for 0.5 seconds before continuing
to impact at a rate of 3100 IPM, providing the user with
greater control and reducing the chance of overtightening or
damaging material.
When set in reverse, the tool will impact at a normal speed
and rate of 3100 IPM. Upon sensing that the fastener has
broken free, the tool will cease to impact and will reduce
speed to help prevent "run-off" of loose hardware.

Usage (Fig. A)
CAUTION: Ensure fastener and/or system will
withstand the level of torque generated by the tool.
Excessive torque may cause breakage and possible
personal injury.
1. Place the accessory on the fastener head. Keep the tool
pointed straight at the fastener.
2. Press variable speed trigger switch
Release variable speed trigger switch to stop operation.
Always check torque with a torque wrench, as the
fastening torque is affected by many factors including
the following:
Voltage: Low voltage, due to a nearly discharged
‑
battery, will reduce fastening torque.
Accessory size: Failure to use the correct accessory
‑
size will cause a reduction in fastening torque.
