- Page 8 General warning for use ■ (common to all lifting clamp models) Be sure to select proper model clamps for use. Pay special attentions to keep the lifting direction (rope angle). Confirm the weight of the load. Do not exceed maximum capacity (designated ton) on clamps.
- Page 9 Never lift two or more steel plates or steel members at a time. The load may move to an unexpected direction when lifted off the ground and as such confirm the center of gravity and the clamping posi- tion for safety when raising. Sufficient caution should be taken until the clamp with the load becomes completely balanced.
