Foreword This safety manual is intended to point out some of the basic safety situations that may be encountered during the normal operation and maintenance of your machine and to instruct you in safety practices for dealing with these conditions. This manual is NOT a substitute for the manufacturer’s operator’s manual(s). Additional precautions may be necessary, or some instructions may not apply, depending on equipment, attachments and conditions at the jobsite or in the service area.
A Word to the User/Operator It is YOUR responsibility to read and understand this safety manual and the manufacturer’s manuals before operating this equipment. This safety manual takes you step by step through the working day. Graphics have been provided to help you understand the text. Hazard recognition and accident prevention depend upon you being alert, careful and properly trained in the inspection, operation, transport, maintenance and storage of this equipment.
Follow a Safety Program For Safe Operation You must be a qualified and authorized operator for safe operation of this machine. You must clearly understand the written instructions supplied by the manufacturer, be trained — including actual operation — and know the safety rules and regulations for the jobsite. It is a good safety practice to point out and explain safety signs and practices to others, and to make sure they understand the importance of following these instructions.
Follow a Safety Program Know the Rules Most job sites have rules governing equipment use and maintenance. Before you start work at a new location, check with the supervisor or safety coordinator. Ask about the rules you will be expected to obey. OSHA enforces federal laws within the United States that apply to the safe operation, application and maintenance of equipment on some jobsites. It is the employer’s responsibility to comply with these laws.
Follow a Safety Program Know the Equipment Read and understand the DANGER, WARNING, CAUTION and NOTICE safety labels and other informational signs on the machine and the attachments, and in the manufacturer’s operating manuals. Ask your supervisor or dealer to explain any information you do not understand. Failure to obey safety instructions could result in death or serious injury. ? lbs Know the following about your equipment: • Function, purpose and use of all controls. • Correct operation speeds.
Prepare for Safe Operation Check the Machine Before beginning your work day, inspect the machine and have all systems in good operational condition. • Perform daily and periodic service procedures as instructed by the equipment manufacturer. • Check for broken, missing, loose, or damaged parts. Make necessary repairs. • Check that all drum mounting bushes are pliable and free from damage. • Check the water sprinkler system. Open the valve and make sure water flows through every hole in each spray bar.
Prepare for Safe Operation Clean Up Clean windows, lights, mirrors, and safety signs. Make sure the operator’s area, steering levers, pedals, joysticks, steps, and grab handles are clean. Oil, grease, snow, ice, mud, or debris in these areas could cause you to slip and fall, or lose control of the machine. Clean your boots of excess mud before entering the machine. Remove all personal items or other objects from the operator’s area. Secure these items in a toolbox or remove them from the machine.
Start Safely Mount and Dismount Properly Warn Personnel Before Starting Always use three-point contact when mounting or dismounting the machine. Three-point contact means one hand and two feet, or two hands and one foot, in contact with the machine at all times. Before starting, walk completely around the machine. Make sure no one is under the machine, on it, or close to it. Let others know you are starting up and don’t start until everyone is completely clear of the machine.
Start Safely operating manual(s). Jump-starting is a two-person operation. The operator must be in the operator’s seat when jump-starting so the machine will be under control when the engine starts. Wear appropriate PPE before attempting to jump-start your machine. WARNING! A battery explosion or a run-away machine could result from improper jump-starting procedures. (See page 38, Battery Hazards.
Operate Safely Work on Slopes Safely When working on slopes, avoid side-hill travel whenever possible. It is generally safer to operate up and down the slope. Remember the danger of sliding and/or tipping on steep slopes is always present, regardless of how heavy or stable your machine may appear to be. Always use seat belts if your machine is equipped with a ROPS. If equipped, make sure foldable ROPS is upright. Keep your hands and feet inside the cab at all times.
Operate Safely Avoid steep slopes or unstable surfaces. If you must drive on a slope, travel at an appropriate speed and with extreme caution. Do not drive across an excessively steep slope under any circumstances. Travel straight up and down the slope. Before operating on slopes, check the surface conditions for adequate traction. Loss of traction can cause the machine to slide and tip. Rules of the Road WARNING! Avoid death or serious injury.
Operate Safely Exhaust Fumes in a Closed Space Can Kill Loading and Unloading Safely Vent exhaust and assure a flow of fresh air when an internal combustion engine is used in a closed space. Always wear your seat belt/operator restraint when loading or unloading your machine from a transport device, such as a flatbed truck. WARNING! Exhaust fumes can kill. Do not breath exhaust fumes from any kind of engine.
Operate Safely machine is equipped with brakes operable from the hauling vehicle, check to make sure they are operating properly. Always be sure the portability or transport wheels, on machines so equipped, are locked in the lowered position. Check all tires for proper pressure, excessive or abnormal wear, and potentially dangerous cuts, bruises or bulges. Have any problems corrected before proceeding.
Operate Safely Towed Rollers Landfill Compactors Most general safety precautions covered earlier in this manual are also applicable to towed roller operation. There are many precautions specific to towed rollers that must be taken. Study your manufacturer’s manual for instructions on your specific towed roller. Consult the manufacturer or dealer with any concerns.
Perform Maintenance Safely Know What You’re Doing Protect Yourself Maintenance on this type of machine is not for inexperienced or untrained personnel. It can be hazardous unless performed properly. Be sure you have the necessary skill, information, correct tools and proper equipment to do the job safely. Wear all the personal protective clothing and PPE issued to you or called for by job conditions or your supervisor. Be sure to maintain the equipment according to the manufacturer’s instructions.
Perform Maintenance Safely Prepare the Work Area • Position the machine on a level area out of the way of other working equipment. • Make sure there is adequate light, ventilation and clearance. • Remove oil, grease or water and dry slippery surfaces. • Clean around the area to be serviced to minimize contamination. Prepare the Machine Stored energy sources (electrical, mechanical, hydraulic, pneumatic, chemical, thermal, etc.
Perform Maintenance Safely Use Jacks and Hoists Carefully Fuel Hazards Safety stands or blocks must be located on a rigid part of the machine. Do not position stands under axles or wheel supports that may rotate. Refer to manufacturer’s manual. WARNING! Avoid serious injury or death. Always use approved fuel containers and/or fuel dispensing equipment to reduce the risk of explosion or fire. WARNING! Prevent crushing injury. Never use concrete blocks for supports.
Perform Maintenance Safely Hydraulic Fluid Injection Hazard High pressure fluid can inject into the body Fluid injection injuries are not always obvious. Victims have reported such injuries feel like a bee sting or splinter under the skin. If you suspect you have a fluid injection injury, do not take chances. Seek proper medical care immediately. If any fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type of injury.
Perform Maintenance Safely Avoid Explosion WARNING! Avoid serious injury from explosion. Lead-acid batteries produce extremely explosive gases especially when being charged. Keep arcs, sparks, flames and lighted tobacco away. • Do not smoke near batteries. • Keep them away from arcs, sparks and open flames. • Provide adequate ventilation. • Make the final cable connection to the engine or the furthest ground point away from the battery. Never make the final connection at the starter or dead battery.
Perform Maintenance Safely Keep wheel lug nuts tightened to manufacturer’s recommendations. An increase in tire pressure during operation is normal, and should NOT be reduced. Never reinflate a tire that has been run flat or seriously under-inflated without removing the tire from the wheel. Have the tire and wheel closely inspected for damage before remounting. Avoid tire explosion Never cut or weld on a wheel with an inflated tire mounted on it. This could cause explosive decompression.
