PRECAUTIONS WHEN OPERATING
Cautions on traveling on slopes
When traveling on slopes or grades, be careful that the machine does not tip (roll) over or slide.
Never travel on slopes that are too steep
• for the machine to maintain its stability (maximum gradeability: 30°, lateral tipping angle: 10°). Note that in reality, the machine’s stability becomes lower than the above values depending on the working condition.
• When traveling on slopes or grades, drive slowly in 1st (low) speed. When descending a slope, slow down the engine speed. Do not descend slopes in reverse.
• Do not change directions on slopes or traverse slopes. First return to a flat surface, and then take an alternative path.
• The machine may slip sideways even on a slight slope if the ground is covered with grass or dead leaves, or when traveling on a wet metal plate or frozen surfaces. Make sure the machine is never positioned sideways on slopes. If the machine is stalled on the slope,
• return each operating lever to the neutral position before restarting the engine.
• When climbing a hill, keep the operator’s seat facing the hillside. When descending a hill, keep the operator’s seat facing the downhill direction. In either case, travel must be done while paying attention to the ground in front of the machine.
• When traveling on slopes, lower the bucket to a height of 20 to 30 cm (8 to 12 in.) above the ground. When climbing a steep slope, extend the hoe attachment to the front. In emergencies, lower the bucket to the ground and stop the machine.

SAFETY
AG7A040
PRECAUTIONS WHEN OPERATING
Operate the machine on snow or ice with extra care
• When traveling on snow or on frozen surfaces, drive at a low speed and avoid starting, stopping or changing directions abruptly. In the snowy area, the road shoulder and
• objects placed beside the road are buried in the snow and cannot be seen. There is a hazard of the machine tipping over or hitting covered objects, so always carry out operations carefully.
• If the machine enters deep snow, there is a hazard that it may tip over or become buried in the snow.
Be careful not to drive beyond the road
shoulder or to get trapped in a snow drift.
• With frozen ground surfaces, the ground becomes soft when the temperature rises, and this may cause the machine to tip over, resulting in an operator trapped inside the machine. When parking the machine on an unstable
• ground, lower the dozer blade.
Do not move the bucket over the heads of people
Ensure driver’s safety when loading
Do not load a truck unless the truck driver is in a safe place.
Never swing or position the bucket over a
• person or the cab room.
• Load the truck from the rear.
Moving the bucket over the heads of people entails the danger of the load spilling or the sudden dr
opping of the bucket.

PRECAUTIONS WHEN OPERATING
Keep a safe distance from the overhead high-voltage cables
Never bring any part of the machine or loaded material to near to the high voltage cables unless all safety precautions required by the local and national authorities have been installed. If a person comes near to the machine that is discharging sparks or located near to or in contact with the power source, there is a hazard of electric shock and death.
Always maintain a safe distance between
• the machine and the high-voltage electric cable. Check with the local power company
• about safe operating procedure before starting operations. Consider all cables to be high-voltage
• cables and treat all cables as energized even though it is known or believed that the power is shut off and the cables are visibly grounded.
• Use a signal person to give warning if the machine approaches too close to the high­voltage electric cables. Caution all personnel in the work area not
• to come close to the machine or the loaded material.
• Pay also careful attention to the high­voltage electric cables buried underground.

PRECAUTIONS WHEN OPERATING
Watch out for hazardous working conditions
• Never undercut a high bank. Doing so is dangerous as it may cause ground collapse. Do not operate in places where there is a
• danger of falling rocks.
Do not enter areas where there is soft
• ground. Doing so could cause the machine to tilt under its own weight, resulting in a machine tipping over or sinking into the ground.
• Maintain a safe distance between the machine and the edge of the digging site. Do not dig the ground under the front of the machine. When working close to the cliffs or road
• shoulders, to make it easier to escape if there is any problem, set the crawlers at right angles to the cliff or road shoulder and the dozer blade to the front when carrying out operations.
• Do not come close to unstable grounds (cliffs, road shoulders, deep ditches). If the ground should collapse under the weight or vibration of the machine, there is a hazard that the machine may fall or tip over.
· Remember that the soil after heavy rain
or blasting is weak. The ground of top of the embankment
·
and of the circumferences of the excavated ditches are also weak.

PRECAUTIONS WHEN OPERATING
• Do not perform demolition work under the machine. There is a hazard that the machine may fall down, because the ground becomes unstable.
• When working on or from the top of buildings or other structures, check the strength and the structure before starting operations. If a building or structure collapses, serious injury or damage will result.
• Do not use the impact force of the hoe attachment for breaking work. There is a hazard of serious injury being caused by flying pieces of broken materials and by the damaged hoe attachment.
Operating on slopes is dangerous
When operating on slopes or grades, slewing or operation of working equipment may cause the machine to lose stability and tip over. Avoid operating on slopes whenever possible.
• When doing demolition work, do not perform demolition above your head. There is a hazard of broken parts falling or of the building collapsing and causing serious injury or damage.
• Level off the work area.
• Avoid slewing to the downhill direction with the bucket full of loaded material. This will reduce the stability of the machine and may result in tipping over.

PRECAUTIONS WHEN OPERATING
Never slew (swing) sideways with a heavy load
The machine can tip over more easily in the lateral direction than in the longitudinal direction.
• Do not slew (swing) sideways with a heavy load at the tip of the hoe attachment. In particular, do not slew (swing) sideways on slopes. The tip of the attachment is heavier for
• machines equipped with breakers, crushers or long arms than for machines equipped with the standard bucket. For such machines with heavier tips, do not perform excavation with the digging arm (boom) facing the downhill direction or operate toward sideways.
Be careful with the overhead objects
When operating under bridges, in tunnels, near electric cables or indoors, be careful not to let the boom or arm hit overhead objects.
Excavators are not designed for lifting loads
This machine is specifically designed for excavation work. Therefore, it has no safety equipment for crane operation. Extreme caution should be paid if the excavator is used for lifting.
Never lift loads in excess of capacity.
• Overload will cause the machine to roll and can result in serious injury or death.
• All rated lift capacities are determined by using a machine placed on a stable and flat ground. For a safe lifting work, the user is expected to make due allowance for the particular job conditions. They include, soft or uneven ground, non-level condition, side loads, dynamic or jerked loads, hazardous conditions, and experience of personnel. The operator and other personnel should fully acquaint themselves with the operator’s manual before operating this machine, and rules for safe operation of equipment shall be adhered to at all times.
• The bucket linkage or lifting device may fail if chains or lifting device are incorrectly attached, resulting in serious injury or death. Do not attempt to pull stumps out of the
• ground when using the machine as a crane. The loads imposed on the machine under this use are completely unknown.
• Do not allow anyone to stand on or under the lifted loads or come close to the work area.

CRAWLER WIDTH SWITCHING

Operate the machine with the maximum crawler width
Always operate the machine with the
• crawler width extended to 1300 mm (51.2 in.) to maximize the machine stability. If the machine is operated with the crawler width narrowed (980 mm,
38.6 in.), the machine may tip over due to its poor stability.
• If the machine must be operated with the narrowed crawler width (980 mm,
38.6 in.), traveling should be done after folding the hoe attachment, lowering the boom to lower the center of gravity and keeping the machine facing forward.
This machine is able to change the crawler width. Normally, it is best to operate with the crawler width extended for machine’s stability.

CAUTIONS ON TRAVELING

Traveling over obstacles (rocks, stumps, etc.) may put a great load on the machine body and may cause damage to it. Avoid crossing over obstacles whenever possible. If you must do so, keep the hoe attachment near the ground, travel at a low speed, and go over the obstacle at the center of the crawler.
Cautions on traveling in 2nd (High) speed
Cautions on using machine in water
If the rear of the machine is submerged in water as shown in the figure above, it causes the radiator fan to turn in water, resulting in damage to the fan. The rear of the machine must not be submerged.
• On uneven ground, maintain the low speed and avoid starting, stopping or changing directions abruptly.
• When traveling in 2nd speed, do so with the dozer blade at the front.
Allowable water depth
• Use the machine in water only when the
water is up to the middle of the shoe slide (1). For those parts used in water for a long
• time, apply enough grease until the old grease is expelled.
• Never submerge the slew bearing or main body in water or sand. If submerged, contact a Takeuchi service agent for inspection.
