Theta Controller
3.5 Tool Operation
ROTATING SPINDLE
To Avoid Injury:
•
Always wear eye and foot protection when operating and when in areas where power tools are
being used.
•
Keep all body parts and clothing away from the rotating end of the tool. Dress properly. Do not
wear loose-fitted clothing or jewelry.
TORQUE REACTION FORCE
To Avoid Injury:
•
Be alert and maintain good balance, footing, and posture at all times in anticipation of the tool's
torque reaction. Do not over-extend or over-reach.
•
Be prepared for the change in direction and or a higher reaction force when a tool is in reverse.
•
The start lever should be positioned to avoid trapping the operator's hand between the tool and
the work piece.
TOOL MAY NOT SHUT OFF
To Avoid Injury:
•
If the tool does not shut off at the end of the tightening cycle, contact the person responsible
for tool installation or repair. Note: When the tool does not shut off, a stall condition occurs. A
stall condition can cause a higher than expected torque reaction impulse.
•
Ensure tool is properly installed, adjusted and in good working order.
•
Do not use the power tool if the switch does not turn it on and off.
•
Apply the tool to the joint following all recommendations in this manual
•
Check to ensure the drive socket is fully seated and locked into position before connecting
power to the tool.
Prepare to resist the tool's torque reaction:
Start the tool by depressing the start lever or trigger.
Release start lever after the cycle is complete.
3.5.1 Directional Control
UNEXPECTED REACTION FORCES
To Avoid Injury:
•
Be prepared – when a tool operates in reverse, the tool's torque reaction is opposite to the
reaction produced when the tool operates in forward direction.
•
The tool can have a higher initial reaction force when loosening a fastener.
•
Always stop the tool before changing direction of spindle rotation.
3.5.2 Torque Reaction Devices
PINCH POINT BETWEEN TORQUE REACTION BAR AND WORK PIECE
To Avoid Injury:
•
Never place any body part between a reaction bar and the work piece.
•
Before starting the tool, position the reaction bar firmly against a stationary rigid member that is
opposite to the spindle rotation.
Torque reaction devices absorb tool torque reaction forces. Always use reaction devices when high
reaction force could injure an operator.
Some reaction devices may require modification to fit the application. Follow all appropriate
installation instructions.
