Frequently Asked Questions - BD-78D-C Vevor

How to use the BD-78D-C torque multiplier?

Insert the impact socket into the output end connected to the handle. Place the rocker arm on the nut and turn in the desired direction. For final tightening, do not apply a force greater than 100 N.m.

What is the gear ratio of the BD-78D-C?

The ratio is 1:64, meaning that for each turn of the handle, the output makes 1/64th of a turn, thus multiplying the applied torque.

What is the maximum torque this tool can provide?

The maximum output torque is 6800 N.m, allowing to loosen even the tightest wheel nuts.

Can this tool be used with an electric impact wrench?

No, it is designed for manual use. Do not use an impact wrench or a pinch bar on the rocker arm, as this could damage the tool.

What types of sockets can I use?

Use impact sockets suitable for the size of your vehicle's nuts. The tool accepts standard sockets.

How to maintain the torque multiplier?

After each use, wipe the tool to remove moisture and dirt. Store it in a dry place to prevent rust.

What safety precautions should be taken?

Wear gloves and safety glasses. Do not place your fingers in the jaws. Do not use the tool as a hammer.

Can I use this product to tighten nuts to a specific torque?

It is not recommended for precision tightening as it has no torque measurement function. Use a torque wrench for final tightening according to the manufacturer's specifications.

What to do if the nut does not loosen?

Check the rotation direction: turn the rocker arm in the direction that brings the handle closer to the bolt. If the force is insufficient, make sure the 1:64 ratio is being used.

Turn the rocker in the direction which makes the handle close to the side of another screw bolt extent that the handle is closely against the side of the screw bolt;
