Page 40: Loadisc Reaction Washer Overview
The LoaDisc Reaction Washer is the first reaction arm replacement device for torque wrenches and is exclusive to JETYD Corporation. The LoaDisc is a hex shaped washer that fits under a standard nut and is used in conjunction with a double-layered (concentric) socket. The double- layered socket turns the nut using the inner socket, and the gun reacts on the washer with the outer socket. -
Page 41: Safety
When not in use, properly store the LoaDisc drivers and any unused LoaDiscs. Personal Protective Equipment Always wear the appropriate personal protective equipment when operating the FRL and jGun including gloves, safety goggles, hearing protection, hard hat, and safety shoes. JETYD Operations Manual... -
Page 42: Loadisc Requirements
All joint specifications (bolt size, material, gasket type, etc) must be provided or recorded by a trained JETYD Representative. Always use authentic JETYD accessories when installing the LoaDisc. Never use a substitute torque wrench or socket/driver. LoaDisc Setup and Use Proper setup and use of the LoaDisc reaction washer ensures accurate results and safe operation. -
