WARNING
Models 2112, 2112S and 2121 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.
