USING THE POWER MANAGEMENT SYSTEM
Air wrenches are not torque control devices. Fasteners
with specific torque requirements must be checked
with suitable torque measuring devices after
installation with an air wrench.

Model IR--C2112 Air Wrench incorporates 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.
SERVICING THE TOOL
Lubrication
Ingersoll--Rand No. 50
Always use an air line lubricator with these tools.
We recommend the following Filter--Regulator--Lubricator
(FRL) Unit:
For USA use Unit Number C18--03--FKG0--28
After each eight hours of operation,
unless an air line
lubricator is used, detach the air hose and inject about
1--1/2 cc of Ingersoll--Rand No. 50 Oil into the Inlet
Bushing (22).
