Komatsu — Traveling On Slopes

Safety - Section 20 OM2044 Page 20-6 Check for flat tires periodically during a shift. If the truck has been operating on a “flat”, the truck must not be parked indoors until the tire cools. If the tire must be changed, DO NOT stand in front of the rim and locking ring when inflating a tire mounted on the machine. Observers must not be permitted in the area and must be kept away from the side of such tires. Lower the dump body and move the dump lever to the FLOAT position before traveling. If the engine stops when the machine is in motion, the emergency steering system will be activated.

Apply the brakes immediately and stop the machine as quickly and safely as possible (off of the haul road, if possible). Apply the parking brake. Precautions When Traveling In Reverse Before operating the machine or work equip- ment, do as follows: A tire and rim assembly may explode if subjected to excessive heat. Personnel must move to a remote or protected location if there is a fire near the tire and wheel area or if the smell of burning rubber or excessively hot brakes is evident. Ensure the backup alarm works properly.

If the truck must be approached, such as to fight a fire, those personnel must do so only while fac- ing the tread area of the tire (front or back), unless protected by use of large heavy equip- ment as a shield. Stay at least 50 ft. (15 m) from the tread of the tire. Sound the horn to warn people in the area. Check for personnel near the machine. Do a thorough check behind the machine. When necessary, designate a person to watch the area for the truck operator. This is particularly necessary when traveling in reverse. When operating in hazardous areas and areas with poor visibility, designate a person to direct work site traffic.

In the event of fire in the tire and wheel area (including brake fires), stay away from the truck for at least 8 hours or until the tire and wheel are cool. DO NOT allow any one to enter the line of travel of the machine. This rule must be strictly obeyed even with machines equipped with a back-up alarm or rear view mirror. Keep serviceable fire fighting equipment on hand. Report used extinguishers for replacement or refilling. Always move the directional control lever to PARK (this will apply the parking brake) when the truck is parked and unattended. DO NOT leave the truck unattended while the engine is running.

Traveling On Slopes Traveling on slopes could result in the machine tipping over or slipping. NOTE: DO NOT use wheel brake lock when parking the truck. DO NOT change direction on slopes. To ensure safety, drive to level ground before turning. Park the truck a safe distance away from other vehicles as determined by the supervisor. DO NOT travel up and down on grass, fallen leaves, or wet steel plates. These materials may make the machine slip on even the slightest slope. Avoid traveling sideways, and always keep travel speed low. Stay alert at all times! In the event of an emergency, be prepared to react quickly and avoid accidents. If an emergency arises, know where to get prompt assistance.

When traveling downhill, use the retarder to reduce speed. DO NOT turn the steering wheel suddenly. DO NOT use the foot brake except in an emergency. Traveling In The Truck When traveling on rough ground, travel at low speeds. When changing direction, avoid turning suddenly. If the engine stops on a slope, apply the service brakes to fully stop the machine. Move the directional control lever to the PARK position (this will apply the parking brake).
