MWO 9-2330-390-25-1 C-3 APPENDIX C: TOP AND BOTTOM BEAM AND HYDRAULIC LIFT CYLINDER REMOVAL / INSTALLATION (Con’t). WARNING • Use extreme caution when lowering top and bottom beams and placing on the ground. Ensure that lifting device is secure and all personnel stand clear. Failure to follow this warning may cause serious injury to personnel or damage to beams and positioning cylinders. 9. Lower top and bottom beams to the ground and support on wooden blocks or other cribbing if necessary. 10. Swing lift cylinders forward to rest on suspension frame. This will counteract the removal of the top and bottom beam. WARNING • DO NOT disconnect hydraulic lines and fittings while engine is running or before hydraulic system pressure has been released. When engine is running, hydraulic system is under pressure. Dolly set must be fully lowered on to the blocks and the engine must be shut down before lines and fittings are disconnected. A line or fitting disconnected under pressure will explode with great force and cause serious injury or death to personnel.
