OPTIONAL REAR SAFETY TRIGGER OPERATION
If the tool is fitted with the Rear Safety Trigger then both the soft start trigger and the rear safety trigger
have to be pressed before the tool can operate. If either of the triggers is released the tool will stop.
To set the required torque, refer to the
SETTING TORQUE FOR BOLT TIGHTENING
section.
When running the tool both the rear safety trigger and the soft start trigger will need to be pressed to
rotate the drive.
10.
Fit the wrench with the correct size impact socket to suit the bolt to be tightened and retain with
ring and pin system.
11.
Rotate the handle to convenient position relative to the reaction arm.
12.
Fit the tool onto the bolt to be tightened / un-tightened with the reaction arm adjacent to the
reaction point (See “Torque Reaction” section).
13.
Move the direction selector switch (E) from the neutral position and into either forward or reverse
as required.
14.
Press the rear safety Trigger fully in then Squeeze the soft start trigger (F) partially to bring the
reaction arm into contact with the reaction point.
15.
Press the rear safety Trigger fully in then fully press the soft start trigger (F) and keep pressed
until the tool stalls (when tightening) or the fastener is released (when un-tightening). If either
trigger is released before the wrench stalls, full torque will not be applied to the bolt. Once the air
motor stalls do not “blip” the trigger, or incorrect torque will be applied. Release the soft start
trigger then the rear safety Trigger .
16.
In use, this tool must be supported at all times in order to prevent unexpected release of a fastener
or component failure.
17.
If a fastener will not un-tighten when the tool is set to maximum on the calibration certificate, do
not “blip” the trigger repeatedly, use tooling of higher torque output.
18.
Remove tool from bolt.
MAINTENANCE AND RECALIBRATION
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).
