WARNING:
Since accessories, other than those
offered by Mac Tools,
have not been tested with this
product, use of such accessories with this tool could be
hazardous. To reduce the risk of injury, only Mac Tools
recommended accessories should be used with
this product.
Recommended accessories for use with your tool are
available at extra cost from your local dealer or authorized
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.
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:

Worklights (Fig. E)
CAUTION: Do not stare into worklights.
Serious
eye injury could result.
The worklights
6
are located around the quick release
chuck. The worklights are activated when the trigger is
depressed. If the trigger switch remains depressed, the
worklights will remain on.
The beam will automatically turn off 20 seconds after the
trigger switch is released.
nOTE:
The worklights are for lighting the immediate work
surface and are not intended to be used as a flashlight.
A forward/reverse control button
4
determines the
rotational direction of the tool and also serves as a
lock-off button.
• To select forward rotation, release the trigger and
depress the forward/reverse control button on the right
side of the tool.
• To select reverse, depress the forward/reverse control
button on the left side of the tool.
nOTE:
The center position of the control button locks the
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.
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.
Usage (Fig. A)
WARNING:
Use only impact accessories. Non-impact
accessories may break and cause a hazardous
condition. Inspect accessory prior to use to ensure that
it con tains no cracks.
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.
