Page 2: Safety Instructions
○Make this manual available with all the appropriate people. ○ If you lose the warning and caution labels, please contact Uryu or the supplier from whom you purchased your UAAMC tool. We request you to make the labels available with yours for safety. - Page 3 -Use correct hoses and always check for damaged or loose hoses and fittings. Whipping hoses can cause severe injury. -An accessible means to shut off air supply should be provided at each tool station. -Do not use quick-disconnect couplings at tool inlet. Use hardened steel (or material with comparable shock resistance threaded hose fittings.

Page 4: Residual Risks
Noise Unprotected exposure to high noise levels can cause permanent, disabling, hearing loss and other problems such as tinnitus (ringing, buzzing, whistling or humming in the ears). Risk assessment and implementation of appropriate controls for these hazards are essential. Note : ISO 9612 describes the guidelines for the measurement and assessment of exposure to noise level at the workplace. -
Page 5: Maintenance Instructions
-Continuous satisfactory operation depends upon proper tool care and regular maintenance. -Get the tool serviced by a qualified repair person. -Use URYU genuine parts for replacement. This will ensure that the safety and the optimum performance of the tool are maintained... - Page 6 Lubrication -It is important to lubricate regularly to get maximum performance and trouble-free operation. -For air motor, supply light turbine oil, ISO VG32 properly through air inlet (see table 1-A) or line lubricator (see table 1-B). -For air motor bearings, coat one-third of the bearing with high quality grease, Multemp PS No. 2 (see table 2) or equivalent.

Page 8: Before Usage
1. Before Usage Uryu pneumatic torque and angle transducerized UAAMC oil pulse tool (hereunder, UAAMC) is designed to tighten and loosen fasteners with the hydraulic impact / pulses created by compressed air. Never modify or operate UAAMC for the purpose other than the intended usage. This will cause operators death or severe injury. - Page 9 ○Stay alert, watch what you are doing and use common sense when operating the tool. Do not use any tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating tools may result in serious personal injury. A moment of inattention while operating power tools may result in serious personal injury.

Page 10: What Is The Electronically Controlled Oil Pulse Wrench Angle Detection Type
Angle(deg) 2.2 Features Sensor：Uryu unique non-contact and magnetostrictive torque sensor is adopted. The angle sensor uses a resolver, which is durable without wear on the sensor shaft. Oil Pulse：Equipped with an auto-relief mechanism, achieves high accuracy, high efficiency, and high durability. -

Page 13: Points Of Tool Operation And Handling
6. Points of Tool Operation and Handling 6.1 How-to-use (1) Pulling the valve lever rotates the socket spindle. (There are two rotational speeds and a slow rotation function.) (2) Determine the direction of rotation, and tighten the socket securely to the bolt (or nut). (3) When the bolt (or nut) is seated and the dynamic torque reaches "START", torque/angle measurement starts. -

7. Tool Setup 7.1 Tool Adjustment and Cut Value Determination Make the controller settings. See further info from the manual of controller. ○Basic Settings ・Input the CAL value on tool. ・START value: 2 - 3 % of CAL value ・The next formula should be adhered to: High Torque＞CUT torque＞Snug torque＞ Low Torque ○MODE Setting Make it 5 to operate the pneumatic torque transducerized UAAMC. -
Page 15: Tool Adjustment Points
※ 1 Pulse number > 5? Check on the torque wave. ※ 2 Does the controller read 1.5 seconds or less? ５ ４ ３ １ ２ 7.2 Tool Adjustment Points 7.2.1 Determination of start torque Torque may be generated before seating due to the characteristics of the workpiece. Check the tightening waveform to see if torque is generated before seating, and adjust the start torque within the range shown in the figure below. - Page 16 7.2.2 Spike in Displayed Torque / TORQUE-HIGH If the displayed torque on the controller exceeds the cutting torque (set value) or TORQUE-HIGH frequently occurs, take measures such as residual pressure treatment or lowering the air pressure to achieve more stable tightening. 7.2.2.1 Residual Pressure Treatment The residual air pressure may cause UAAMC to keep pulsing after the external valve is closed.
- Page 17 If there is a sharp increase in displayed torque per pulse close to cut torque, you will see over-torqueing / torque high error frequently. The decent adjustment of air pressure will allow dynamic torque to make a liner increase per pulse, which will lead to the better accuracy. Peak torque per pulse, close to cut torque, difference between air pressures Air pressure: 0.6MPa Air pressure: 0.4MPa...

Page 18: Setting The Angle
Enlarged Pictures of Connector between Handle and Front Casing (3) Take out the Oil Pulse unit, and adjust the Relief Valve Spindle on the Front Liner Plate side with the Allen Wrench (1.5mm or 2mm) provided. Turning the relief valve clockwise increases the torque, while turning it counterclockwise decreases the torque. - Page 19 Angle measurement has three measurement points in free・st-sn・sn-ct. sn-ct ：Angle from snug torque to 10msec after final pulse st-sn ：Angle from start torque to snug torque free ：Measured from 400ms prior to start torque Cut Torque Angle Wave Snug Torque Torque Wave Start Torque free...
- Page 20 7.3.1 Setting Snug Torque (Angle Measurement Start Torque) and Angle Upper and Lower Limits To measure the tightening angle, the snug torque is used as the starting point, so stable angle measurement is performed by adjusting the snug torque. The angle upper and lower limits are determined from the measured angle of the tightening result performed normally.

Page 21: Trouble Shooting
8. Trouble shooting When trouble occurs during use after installation of the tool, check as follows. 8.1 Tool does not run ○When installing, removing, or changing wiring of the tool, turn off the power to the controller and ensure safety. Carry out work carefully at the place. ○By operating the controller according to the instruction manual of each controller. -
Page 22: Tool Does Not Stop
8.2 Tool does not stop The transmitted torque from the tool to the workpiece changes due to changes in the tightening conditions, such as changes in the workpiece or cracks in the socket, and the tightening time and number of pulses change. -
Page 23: Maintenance And Management
9. Maintenance and management 9.1 Cautionary instructions in handling ○Check each part of the tool for looseness, wear, etc. ○The sensor installed in UA-AMC wrench is a magnetostrictive sensor. If the magnet is brought close to the tool, it may be affected by magnetism and cause malfunction. ○Supply a small amount of turbine oil ISOVG32 to the motor section.
