MANAGEMENT
DIAL
Models 2131 and 2131–2 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.
