WARNING
The 2131 series of Impact Wrenches incorporate a Power
Management System that allows the operator to select four
power output settings. These settings range from minimum
power output through maximum power output in the
forward direction only. The Air Wrench will always operate
at maximum power output in the reverse direction, no
matter what power output level is selected.
The four power setting indicators of increasing size on
the rear of the housing indicate increasing power output
levels, are for reference only and DO NOT denote a
specific power output. The smallest power setting
indicator designates minimum power output, the two
middle power setting indicators denote medium power
outputs and the largest power setting indicator denotes
maximum power output.
The power output can be further reduced in forward or
reverse by using the variable throttle. Air supply
systems which do not deliver adequate air pressure can
affect power output at all settings.
