Equipment Seat Belts Should Be Used at All Times Whenever the engine is running, the operator should be seated at the control station with the seat belt properly engaged. Rough Operation May Require Use of Certified Safety Equipment Work in mines, tunnels, deep pits or on loose or wet surfaces could produce danger of falling rock, roll over or hazardous flying objects. Additional protection for the operator’s cab could be required in the form of a FOPS/ Falling Object Protective Structure, ROPS/Roll Over Protective Structure and/or OPS/Operator Protective Structure reinforce- ment system.
Keep a Fire Extinguisher at Hand It is recommended that an appropriately sized (2.27 kg [5 lb] or larger) multi-purpose “A/B/C” fire extinguisher be mounted in the cab. Check and service the fire extinguisher at regular intervals and make sure that all work-site crew members are adequately trained in its use. Any reinforcement system that is installed on the machine must pass safety and certification stan- dards and carry appropriate labeling and rating information.
For example, the most often added type of reinforcement system, FOPS, must meet or exceed Society of Automotive Engineers standard SAE J1356, “Performance Criteria for Falling Object Guards for Wheel loaders.” Maintain Standard Safety Equipment in Good Condition Machinery guards and body panel covers must be in place at all times. Keep well clear of rotating parts. Pinch point hazards such as cooling fan and alternator drive belts could catch hair, jewelry or oversize or very loose clothing. Never attempt to alter or modify any type of protec- tive structure reinforcement system, by drilling holes, welding or remounting or relocating fasteners.
Any serious impact or damage to the system requires a complete integrity reevaluation. Reinstallation, recertification and/or replacement of the system may be necessary. Safety labels must be replaced if they are damaged or become unreadable. The information on labels gives work crew members an important safety reminder. Part numbers for each label and required mounting locations are shown on Pages 1-2 through 1-4 of this section. Install Additional Safety Equipment if Conditions Require When working with a breaker or in some shear work applications, a front guard over the windshield may be required.
The windshield guard may or may not be OPS/certified, depending upon the specific application and working situation. Safety-critical Parts Must Be Replaced Periodically Replace the following fire-related components as soon as they begin to show any sign of wear, or at regular periodic intervals, whether or not deteriora- tion is visible: Fuel system flexible hoses, the tank overflow drain hose and the fuel filler cap. Laminate glass protection for the front, side or rear windows may also be recommended depending upon particular site conditions. Hydraulic system hoses, especially the pump outlet lines and front and rear pump branch hoses.
Contact your Daewoo distributor for available safety guards and/or recommendations if there is any danger of getting hit by objects that could strike the operator’s cab. Make sure that all other work-site crew members are kept well away from the wheel loader and safe from potential hazards. Keep mounting brackets and hose and cable routing straps tight. Hose routing should have gradual bends. Hydraulic Cylinder Seals Require Periodic Replacement Check cylinder drift rate at regular intervals. Maximum allowable rates are included at the end of the Hydraulic section in the Shop Manual. Overhaul seal kits are available through Daewoo.
Movement Alarms If the wheel loader is equipped with an audible travel movement alarm, test the alarm on a daily basis. The audible alarm should sound as soon as the travel system is engaged. 1-10 SAFETY Mega 300-III Shop Manual
