OPERATING INSTRUCTIONS

LUBRICATION

An automatic in-line filter-lubricator-regulator is recom-
mended as it increases tool life and keeps the tool in
sustained operation. The in-line lubricator should be regu-
larly checked and filled with a good grade of 10W machine
oil. Proper adjustment of the in-line lubricator is performed
by placing a sheet of paper next to the exhaust ports and
holding the throttle open for approximately 30 seconds. The
lubricator is properly set when a very light stain of oil collects
on the paper. Excessive amounts of oil should be avoided.

Application of the tool should govern how frequently it is
greased. It is recommended that the idler gears and right
angle gears receive a generous amount of NLGI 2-EP
grease through the grease fittings after 40 hours of opera-
tion.

STORAGE
In the event that it becomes necessary to store the tool for
an extended period of time, it should receive a generous
amount of lubrication at that time and again when returned
to service. The tool should be stored in a clean and dry
environment. This inhibits corrosion of the precision inter-
nal components and bearings.

FOR YOUR SAFETY AND THE SAFETY OF OTHERS, READ AND UNDERSTAND THE SAFETY
RECOMMENDATIONS ON PAGES 2 & 3 BEFORE OPERATING A NUTRUNNER.

TORQUE ADJUSTMENT

The 55NLTVC nutrunner is designed to develop maximum
rated torque at 90 psig. The torque setting is achieved by
entering a number within the tool's torque range into the
torque control monitor. See catalog for torque range of tool.
The torque setting entered into the torque control monitor
must not exceed maximum torque range of tool or the
automatic shut-off device will not function and the tool will
operate as a stall tool. Operator should be prepared to resist
torque reaction until throttle is released.

THROTTLE POSITION

The throttle lever may be repositioned to accommodate
proper location for task and to avoid entrapment. Reposi-
tioning of the angle head is done by loosening housing lock
nut No. 867521, and lifting the angle head until the spline on
the angle head clears the gear case and can be rotated to
the position desired. Lower the angle head back into place
and tighten housing lock nut.

AIR SUPPLY

For maximum performance, use a 1/2" I.D. air hose no
longer than 8' in length. If additional length is required, a
5/8" or larger hose should be connected to the 1/2" hose.

Being careful to avoid endangering adjacent personnel or
yourself,  the air hose should be cleared of accumulated dirt
and moisture, then one (1) teaspoonful of 10W machine oil
should be poured into the tool's air inlet before connecting
the hose to the tool.
