Blow out all hoses before connecting. Visually inspect hoses for damage before use. If using non- Christie supplied hose please ensure hose is correctly rated. Before connection to Christie C-RAD wrench, ensure the direction selector switch (E) is in the neutral (middle) position.
TORQUE REACTION When the Christie C-RAD wrench is in operation the reaction arm rotates in the opposite direction to the output square drive and must be allowed to rest squarely against a solid object or surface adjacent to the bolt to be tightened. (See figure below).
Extreme forces are created which may cause damage to the wrench. If the application does not allow the use of a standard reaction arm, non-standard reaction arms are available. Customers must not modify reaction arms and are strongly advised to contact W. Christie (Industrial) Ltd for technical assistance.
SETTING TORQUE FOR BOLT TIGHTENING Every Christie C-RAD Wrench is supplied with an individual air pressure calibration graph which relates torque output to air pressure. Set the torque output as follows:- 1. Ensure direction selector switch (E) is set to “Forward”.
“blip” the trigger repeatedly, use tooling of higher torque output. 9. Remove tool from bolt. IMPORTANT: If breakdown, malfunction or damage occurs do not attempt to repair, contact W. Christie (Industrial) Ltd immediately on +44 (0)1709 55 00 88.
To prevent premature failure and ensure confidence in torque supply, it is recommended that this equipment is serviced and calibrated at least on an annual basis, by W. Christie (Industrial) Ltd. Check oil level in lubricator and fill if required (See “C-RAD Lubro Pre-Check” Page for details).
WARRANTY Christie C-RAD wrenches come with a one year (1) conditional warranty. Christie C-RAD Wrenches are guaranteed against manufacturer and material defects, but not against abuse, misuse or neglect by the user. The Square Drive is a non warranty item.
