Introduction
Safety Information
Thank you for your purchase of an AcraDyne® HT Series Pneumatic Nutrunner. These Nutrunners offer a reliable and
dependable solution for the installation and removal of heavy-duty fasteners in a variety of industries that require high torque
capability, accuracy, power and safety.
1) WORK AREA
a. Keep work area clean and well lit. Cluttered and dark
areas invite accidents.
b. Do not operate power tools in explosive atmospheres,
such as the presence of ammable liquids, gases or
dust. Power tools create sparks which may ignite
the dust or fumes. Ensure there are no cables or gas
pipes that may cause a hazard if damaged by the tool.
c. Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
d. Be aware of trip hazards such as air lines and
electrical cords in the work area.
3) PERSONAL SAFETY
a. Only qualied and trained operators should install and
adjust tool.
b. Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use a
power tool while you are tired or under the inuence
of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in
serious personal injury.
c. Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
If the maximum duty cycle of the attached tool is
exceeded or the tool temperature exceeds 50° C.,
then the operator should wear protective hand wear
(gloves).
d. Avoid accidental starting. Ensure the switch is in the
off-position before plugging in. Carrying power tools
with your nger on the switch or plugging in power
tools that have the switch on invites accidents.
e. Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal
injury.
f. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
g. Dress properly. Do not wear loose clothing or jewelry.
Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewelry or long hair can be
caught in moving parts.
h. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of these devices
can reduce dust-related hazards.
i. Ensure hose and ttings are securely fastened to
prevent injury from disconnected whipping hose.
Whenever universal twist coupllings are used, lock
pins should be installed and whip check safety cable
shall be used.
j. Always shut-off air supply, drain air hose pressure
and disconnect tool from air supply when not in use,
before making changes to accessories or when in
repair. Air under pressure can cause severe injury.
k. Do not modify tool. Any modication of tool could
result in personal injury.
l. Failure of the workpiece, tool or accessories can
generate high velocity projectiles.
4) POWER TOOL USE AND CARE
a. Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed. Hold tool with a light, safe grip.
b. Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
c. Tool is intended for the use on threaded fasteners with
impact grade sockets. All sockets and extensions should
be secured with pins and o-ring to the tool. Any other
use of this tool is strictly forbidden.
d. Inspect tool to ensure all markings are visible and legible.
e. Operator and maintenance personnel should physically
be able to handle the bulk, weight, and power of the tool.
If not, the use of a balancer is recommended.
f. Should the operator experience discomfort or pain in
the hands, arm or shoulders, do not ignore it and seek
the advice of a qualied medical professional.
CAUTION – Do not use the Acradyne® HT nutrunning system without fully reading this manual and having a complete
understanding of the correct usage of a high torque-delivering tool and any associated reaction bars/accessories.

Air Supply
• Air Hose Size: ½” ID X 3 Meters in Length.
• Air Pressure: 20 - 90 PSI air pressure is recommended
for the most ecient performance. CAUTION: Never use
higher air pressure to increase the output of the tool.
Overloading will drastically shorten the life of all internal
parts.
• Dry and Clean Air: Drain daily and install lter at or near
the take-off point to prevent trouble from foreign matter.
• Air Hose and Joints: Use air hose (the shorter, the
better), joints, and other ttings of good condition and
of proper size to avoid pressure drop.
Lubrication
• Maintenance: Clean, inspect and lubricate all ring gears,
planet gears and bearings every 100,000 cycles. NOTE: All
work must be performed by a trained and certied AIMCO/
AcraDyne repair technician. Replace all worn parts with
original AIMCO/AcraDyne parts.
• For Air motor: Place three drops of light spindle oil properly
through the air inlet daily and at shift change. Always use
AIMCO Motor Oil when lubricating the air motor.
• For Gears and Bearings: Supply recommended high-
quality grease (e.g. Dow Corning, Moly Kote, BR2 Plus
(or equivalents) properly once every 25,000 cycles and
when the tool is overhauled. Over-greasing will cause dull
motion or heating.

1. Connect the Air Hose to the tool’s Air Inlet:

Torque Adjustment
Each AcraDyne HT Air tool is delivered with a Pressure versus Torque Output Calibration Graph (See example).
Calibration Graph (See example). Using a reliable regulator with gauge in the air supply line, adjust the supply air pressure to
correlate with the desired torque output as shown on the specic graph supplied with the tool. Pressure value should be ob-
served and conrmed with the tool trigger depressed and the tool free running.

ENSURE THAT THE ACRADYNE HT PNEUMATIC NUTRUNNER
IS DISCONNECTED FROM THE AIR SUPPLY.
• Orient the Reaction Bar so that the recess above the spline
on the Reaction Bar is oriented towards the rear of the tool
and any reaction foot is oriented away from the tool anvil.
• Install the Reaction Bar onto the splines of the gearbox
ensuring that the Reaction Bar is staying true to the
splines.
• Install the Reaction Bar retaining ring/plate onto the end
of the Gearbox securing the Reaction Bar in place on
the Gearbox. FAILURE TO SECURE THE REACTION BAR
PROPERLY CAN RESULT IN SEVERE INJURY TO THE
OPERATOR AND/OR DAMAGE TO THE TOOL/APPLICATION.
• Reconnect the AcraDyne HT Series Pneumatic Nutrunner to air supply.
• Ensure that the workpiece is securely xed.
THE TOOL HANDLE MUST NOT BE LOCATED AGAINST AN OBJECT OR RESTRICTION DURING OPERATION OF THE TOOL TO AVOID
CREATION OF A PINCH POINT. AN OEM SOURCED OR APPROVED REACTION BAR OR PROPER REACTION ABSORPTION DEVICE MUST BE
IN USE AND IN GOOD CONDITION ANY TIME THE TOOL IS OPERATED. PROPER TORQUE REACTION MANAGEMENT PRACTICES MUST BE
OBSERVED AT ALL TIMES. FAILURE TO UNDERSTAND AND EMPLOY SAFE OPERATING TECHNIQUES CAN RESULT IN TOOL DAMAGE, APPLICATION
DAMAGE, SEVERE PERSONAL INJURY, OR DEATH
When ready to begin tightening:
• Swivel the reaction bar (Slip Ring Equipped Models only) into position minimizing or ideally eliminating any gap between
the Reaction Bar and the Reaction Surface of the application. On Fixed Gearcase models, ensure that reaction absorption
device is congured properly.
• Complete the tightening event.

Sockets
CAUTION IS REQUIRED. FAILURE TO EXERCISE CAUTION
AND CORRECT OPERATING TECHNIQUE CAN RESULT IN
SERIOUS PERSONAL INJURY, LOSS OF LIMB OR DEATH.
Only Impact Grade, Industrial Sockets should be used with
AcraDyne® HT Series Nutrunners. Mechanic-grade chrome
sockets are not to be used as they do not have sucient
structural strength required to deliver the higher torque
loads that an AcraDyne® HT Series Nutrunner is capable of
delivering. In addition, the use of Socket Extensions of any
length are strongly discouraged as they also will experience
failure to an extent where tool damage or operator injury
may occur.
Pinch Point
CAUTION IS REQUIRED. FAILURE TO EXERCISE CAUTION
AND CORRECT OPERATING TECHNIQUE CAN RESULT IN
SERIOUS PERSONAL INJURY, LOSS OF LIMB OR DEATH.
The nature of a Reaction Bar in any continuous drive tool is
to press against an object to counteract Torque Reaction as
the tool is delivering Torque.
The operator must take great care to keep body parts or foreign
matter clear of the area between the Reaction Bar and the surface
it is reacting against.
ANY BODY PART OR FOREIGN MATTER RESIDING IN A
SPACE BETWEEN THE REACTION BAR AND THE SURFACE
IT WILL REACT AGAINST WILL ENCOUNTER SIGNIFICANT
FORCES THAT CAN CAUSE INJURY, LOSS OF LIMB OR
DEATH.
Reaction Bar Guidelines
CAUTION IS REQUIRED. FAILURE TO EXERCISE CAUTION
AND CORRECT OPERATING TECHNIQUE CAN RESULT IN
SERIOUS PERSONAL INJURY, LOSS OF LIMB OR DEATH.
The guidelines offered below are only guidelines. Should
there be any doubt as to the integrity of a proposed reaction
strategy, it is strongly advised to consult with an AcraDyne®
authorized representative prior to executing strategy.
Reaction force is equal to the point being applied. The
magnitude of the reaction force is dependent upon the
perpendicular distance between the point of reaction and
the centerline of the gearbox. In other words, the greater
the distance the lower force experienced. For this reason,
the point of reaction should be kept as far away from the
centerline of the tool gearbox as possible.
Figure 1 – Safe reaction window
AcraDyne® HT Nutrunning Systems deliver high amounts of torque to an application in a continuous drive manner.
As is the nature with all tool systems that function in this manner, high amounts of torque reaction will occur.
AcraDyne® HT systems work with Reaction Bars that engage the tool with a secure spline and when used correctly
counteract the natural torque reaction in use by pressing against a part detail or adjacent nut/bolt.
It is essential that these forces are understood completely by the operator and that the Reaction Bars have been chosen with the
application’s specic geometry in mind.
AcraDyne® offers a range of Reaction Bars from stock and will design specic Reaction Bars to suit specic applications upon request.
It is the user’s responsibility to ensure that the correct Reaction Bar or Tool Holding Fixture is in place PRIOR to use of the AcraDyne® HT
Series Nutrunner.
