Driving nuts and bolts
Use variable speed control with caution for
driving nuts and bolts with socket
attachments. The technique is to start
slowly, increasing speed as the nut or bolt
runs down. The nut or bolt is set when the
socked comes to a stop.
Note: Ensure that no metal particles enter
the power tool. After working at a low
speed for an extended period, you should
operate the power tool at the maximum
speed for approximately three minutes
without load to cool it down.
Cold weather use (32°F)
Due to the lubrication used in the
impacting mechanism, the tool should be
run for three minutes at no load prior to
actual usage. This will warm the lubricant
and provide better performance.
User interface
Status indicator LED
The LED bar at the top of the user interface
illuminates in various colors to help the
user identify the status of the tool. When
the status indicator LED (12) is green, the
tool and battery pack are operating
normally and temperatures are ok. If the
indicator changes to yellow, it means that
the tool or battery temperatures have risen
to a high level, and the use of the tool must
stop to allow the tool to cool off. It is best
to back off the load and give the tool
chance to cool down. If the indicator turns
red, the tool will shut off to protect itself
and/or the
overheating situation.
The status indicator LED (12) will also blink
blue when the speed (14) or mode (16)
buttons are held for 7 seconds. This will
reset the tool settings to factory default.
