3.0 INSTRUCTIONS

Read and understand these operating instructions
before using the Torque Multiplier.

NOTE: DO NOT USE AN IMPACT WRENCH ON THE TORQUE
MULTIPLIER. DAMAGE TO TOOL WILL OCCUR.

1. When using a POWER driven input, lock selector pawl in

neutral position using the neutral positioning set screw (Fig.
3 Item 2).

2. When positioning the torque multiplier, be sure socket

attached to the output is positioned so that the reaction plate
is at a right angle to the fastener. Torque reaction creates a
rotational force in the opposite direction from which input
force is applied. See Application Information section 10.0 for
additional torque multiplier reaction information.

3. DO NOT apply more torque than the application can

withstand. Breakout torque can be greater than input torque.
Allow a minimum of 50% additional tool capacity for breakout
torque. Damaged and corroded fasteners can require even
greater breakout torque capacity.

4. Monitor input torque using a torque wrench. If torque

multiplier is used without a torque wrench, remember that
output torque is signifi cantly greater than the input torque.

5. Increase Torque Multiplier life. Maintain the shortest possible

couple distance between the Torque Multiplier Output (Fig.
6) and the fastener being addressed. Maintain the longest
distance possible between the Torque Multiplier and reaction
point as possible (Fig. 5).

6. Protect your warranty, use Enerpac approved output square

drives and replacement parts only.
