29 WEBM1000 Safety Section (D6T LGP (OEM)) Engine Stopping Width of tracks or tires – Narrower tracks or narrower tires further increase the digging into the ground which causes the machine to be less stable. Implements attached to the drawbar – This may decrease the weight on the uphill tracks. This may also decrease the weight on the uphill tires. The decreased weight will cause the machine to be less stable. Height of the working load of the machine – When the working loads are in higher positions, the stability of the machine is reduced. Operated equipment – Be aware of performance features of the equipment in operation and the effects on machine stability.
Operating techniques – Keep all attachments or pulled loads low to the ground for optimum stability. Machine systems have limitations on slopes – Slopes can affect the proper function and operation of the various machine systems. These machine systems are needed for machine control. Equipment Lowering with Engine Stopped Before lowering any equipment with the engine stopped, clear the area around the equipment of all personnel. The procedure to use will vary with the type of equipment to be lowered. Keep in mind most systems use a high pressure fluid or air to raise or lower equipment.
The procedure will cause high pressure air, hydraulic, or some other media to be released in order to lower the equipment. Wear appropriate personal protective equipment and follow the established procedure in the Operation and Maintenance Manual, “Equipment Lowering with Engine Stopped” in the Operation Section of the manual. Sound Information and Vibration Information Sound Level Information The operator Equivalent Sound Pressure Level (Leq) is 81 dB(A) when “ANSI/SAE J1166 OCT 98” is used to measure the value for an enclosed cab. This proceeding is a work cycle sound exposure level. The cab was properly installed and maintained.
The test was conducted with the cab doors and the cab windows closed. Note: Safe operation on steep slopes may require special machine maintenance. Excellent skill of the operator and proper equipment for specific applications are also required. Consult the Operation and Maintenance Manual, sections for the proper fluid level requirements and intended machine use. Hearing protection may be needed when the machine is operated with an open operator station for extended periods or in a noisy environment. Hearing protection may be needed when the machine is operated with a cab that is not properly maintained or when the doors and windows are open for extended periods or in a noisy environment.
Engine Stopping Do not stop the engine immediately after the machine has been operated under load. This can cause overheating and accelerated wear of engine components. The average exterior sound pressure level is 86 dB(A) when the “SAE J88Apr95 - Constant Speed Moving Test” procedure is used to measure the value for the standard machine. The measurement was conducted under the following conditions: distance of 15 m (49.2 ft) and “the machine moving forward in an intermediate gear ratio”. After the machine is parked and the parking brake is engaged, allow the engine to run for two minutes before shutdown. This allows hot areas of the engine to cool gradually.
Sound Level Information for Machines in European Union Countries and in Countries that Adopt the “EU Directives” The dynamic operator sound pressure level is 79 dB(A) when “ISO 6396:1992” is used to measure the value for an enclosed cab. The cab was properly installed and maintained. The test was conducted with the cab doors and the cab windows closed.
