Precautions

Before beginning installation, operating of machine, or repair of the Dual Lock Tilt Coupler, there are several cautionary notices that should be considered.

1. Dual Lock Tilt Coupler should only be used to perform tasks for which the coupler was designed. Abusing the product and/or using it for purposes for which it was not intended can expose the operator and others to hazards as well as result in damage to the Dual Lock Tilt Coupler, carrier and/or other attachments.

2. Modification to the Dual Lock Tilt Coupler is done at the risk of the owner and may void warranty.

3. In certain boom/stick/work tool positions, the host machine can be at risk for damage by contact of work tool.

4. DO NOT actuate angling of coupler while in process of digging. Angle actuation should be performed while coupler is in the air and not engaged in material.

5. DO NOT operate the Dual Lock Tilt Coupler unless the coupler is fully connected to the host machine. Auxiliary lines must be connected at all times to provide pressure relief.

6. DO NOT operate the Dual Lock Tilt Coupler unless the host machine relief pressure is adjusted to 20700 kPa (3000 psi).
