MAINTENANCE

WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start‑up can causeinjury.
Your impact tool can generate the following maximum
torque values (Speed 3, Speed 2, Speed 1).
NOTE: Output torque is dependent on the speed selected,
with the highest provided in Speed 3.

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
3
to start operation.
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.
‑ Bolt size: Larger bolt diameters generally
require higher fastening torque. Fastening torque
will also vary according to length, grade, and
torquecoefficient.
‑ Bolt: Ensure that all threads are free of rust and other
debris to allow proper fastening torque.
‑ Material: The type of material and surface finish of
the material will affect fastening torque.
‑ Fastening time: Longer fasten ing time results in
increased fastening torque. Using a longer fastening
time than recommended could cause the fasteners
to be overstressed, stripped ordamaged.
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.
Cleaning

WARNING: Blow dirt and dust outofall air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear ANSI Z87.1approved eye
protection when performingthisprocedure.

WARNING: Never use solvents or other harsh
chemicals for cleaning the non‑metallic parts of the
tool. These chemicals may weaken the plastic materials
used in these parts. Use a cloth dampened only with
water and mild soap. Never let any liquid get inside the
tool; never immerse any part of the tool into aliquid.
