CAUTION identies a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury or property and environmental damage.
All personnel involved with the installation, operation or maintenance of these tools must read and
understand all safety instructions contained in this manual. Failure to comply with these instructions
could result in serious injury or property damage.
These safety instructions are not intended to be all inclusive. Study and comply with all applicable
National, State and Local regulations.
ÚEnsure there is enough space in the work area.
ÚKeep the work area clean.
ÚKeep the work area well ventilated.
Personnel Safety:
Ú
Inspect the air supply hoses and ttings. Do not use damaged, frayed or deteriorated hoses.
Make sure the air supply hose is securely attached to the tool.
Ú
ÚEnsure a secure standing position and maintain balance.
ÚMake sure the throttle is positioned relative to the head so the throttle will not become wedged
against an adjacent object in the ON position due to torque reaction.
ÚIf the tool is to be reversed, locate the throttle in a neutral position to prevent entrapment.
Page 6
General Information
ÚKeep the tool clean and dry to provide the best possible grip.
ÚFirmly grasp the handle of the 19RA and apply the socket or bit to the application before starting.
ÚBe prepared for high short-term reaction torques.
Safety working with and around fastening tools:
ÚUse only power tool sockets and bits available from Apex Tool Group.
ÚInspect socket or bit for visible damage and cracks. Replace damaged items immediately.
ÚDisconnect the air supply before installing or replacing the socket or bit.
ÚDo not attach the socket or bit at a slant.
ÚMake sure the socket or bit is fully assembled on the drive and locked in postion.
All personnel must be properly trained before operating the 19RA tools. The 19RA tools are to be
repaired by fully trained personnel only.
1.4 Personal protective equipment
When working
• Wear eye protection to protect against ying metal splinters.
• Wear hearing protection
Danger of injury by being caught by moving equipment.

1.5 Designated use
The 19RA is designed exclusively for fastening and releasing threaded fasteners.
The 19RAA series nutrunners are equipped with an adjustable Clecomatic clutch. The tool will shut off
the instant the clutch reaches its adjustable preset torque. This action provides an accurate method of
controlling torque without sacricing tool speed.
The 19RAS series are stall type nutrunners. The tool runs down the fastener until the torque resistance
in the fastener causes the tool to stall. When the tool stalls, the throttle is released by the operator and
the tool is removed from the application. Stall type tools can produce accurate torques, especially on
applications with varying torque rates; however, their torque output can be easily inuenced by the
operator and by uctuations in the air line pressure. Operators should be instructed to allow the tool to
stall before releasing the throttle and to avoid pulling or wrencing the tool after it stalls.
• Do not modify the 19RA, any guard or accessory.
• Use only with accessory parts which are approved by the manufacturer.
• Do not use as a hammer, pry-bar or any other improper usage.
1.6 Codes and standards
It is mandatory that all national, state and local codes and standards be followed.
1.7 Noise and vibration
Noise level ≤ 75 dB(A) free speed (without load) according to ISO 12100: 2011

General Information
We recommend the use of a reaction bar for higher torque applications to
prevent uncontrollable reaction of the tool when rundown shut off is achieved.
This use is dependent on the following factors: torque, joint, air pressure,
form of tool, and the operator. Consider the use of a reaction bar to prevent
personal injury.
