Rigging-Moving Jaw Safety
When working in or near the jaw, a safety rigging must be installed to ensure that there is no unintended motion of the moving jaw. Apply rigging with at least 2500 kg (5500 lb) capacity between the moving jaw maintenance eye and rear housing lifting eye (moving jaw safety rigging).

Open the jaws of the shear, and place the shear heel on the ground.
Turn off the engine and relieve hydraulic pressure.
Do not operate the work tool unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings could result in machine or work tool damage, serious injury or death.
Personal injury or death can result from sudden work tool movement.Sudden movement of the work tool can cause injury to persons near the work tool.To prevent injury or death, make sure that the area around the work tool is clear of personnel and obstructions before operating the work tool.
Do not strike against the cutter with a hardened steel tool of any kind. The cutter may chip and cause severe injury.
Apply moving jaw safety rigging. Refer to Operation and Maintenance Manual, "Rigging-Moving jaw safety".
Inspect all bolts to the static inspection torque. Refer to table 1.
Table 1
Model Bolt Size Inspection Torque
S2050, and S3050 M20 x 2.5 450 N m (332 lb ft)
S2070, S3070, S2090, and S3090 M24 x 3 800 N m (590 lb ft)
If the inspection torque value is applied in the clockwise direction without any rotation of the bolt, then the inspection passes. If the bolt moves before reaching inspection torque, then proceed to step 5.
If needed, tighten all bolts to the proper torque. Refer to table 2.
