COMPLETE UNDERSTANDING OF THE CORRECT USAGE OF AHIGH TORQUE DELIVERING TOOL AND ANY ASSOCIATED REACTION
BARS/ACCESSORIES.
SAVE THESE INSTRUCTIONS
1) WORK AREA
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) Do not operate power tool in explosive atmospheres such as the presence of flammable liquid, gases or dust. Power tools create sparks which may ignite 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 apower 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.
2) PERSONAL SAFETY
INDICATES CAUTION IS REQUIRED. FAILURE TO EXERCISE CAUTION AND CORRECT OPERATING TECHNIQUE CAN RESULT
IN SERIOUS PERSONAL INJURY, LOSS OF LIMB OR DEATH.
INDICATES WARNING RISK OF CRUSHING. FAILURE TO EXERCISE CAUTION AND CORRECT OPERATING TECHNIQUE CAN RESULT
IN SERIOUS PERSONAL INJURY, LOSS OF LIMB OR DEATH.
a) Only qualified and trained operators should install and adjust tool.
b) 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).
c) Avoid accidental starting. Ensure air is off before connecting to air hose. Carrying power tool with your finger on the throttle, or connecting to the air hose with
your finger on the throttle, invites accidents. Never carry the tool by air hose. Release throttle in case of an interrruption of the air supply.
d) Remove any adjusting key or wrench before turning the tool on. Awrench or akey left attached to arotating part of the tool may result
in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f) Dress appropriately for your environment. Do not wear loose clothing or jewelry. Keep hair, clothing, hands and gloves away from moving objects such as drives,
sockets and extensions. Loose clothing, jewelry, gloves or long hair can get caught in moving parts. Direct the tool’s cold exhaust away from you, your co-worker,
work surface and hands. Keep hands warm.
g) 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.
h) Ensure hose and fittings 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.
i) 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.
j) Do not modify tool. Any modification of tool could result in personal injury.
k) Failure of the workpiece, tool or accessories can generate high velocity projectiles.
3) 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 trigger does not turn it on and off. Any power tool that cannot be controlled with the trigger 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, wieght, and power of the tool. If not, the use of a balancer is reccommended.
f) Should the operator experience discomfort or pain in the hands, arm or shoulders, do not ignore it and seek the advice of a qualified medical professional.

Reaction Bar Safety
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 SPECIFIC GEOMETRY
IN MIND.
ACRADYNE® OFFERS A RANGE OF REACTION BARS FROM STOCK AND WILL DESIGN SPECIFIC
REACTION BARS TO SUIT SPECIFIC 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.
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.
FIGURE 1 – SAFE REACTION WINDOW
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.
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 sufficient 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.

Reaction Bar Safety
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.
