1) the machine should be inspected around the machine again before the operation of the machine, and check whether there is a person or object. Only when sitting on the chair can we start and operate the machine. When the engine is started, the alarm should be honed. No one outside the driver is allowed to enter the cab or stay on the body.
2) before driving, check the position of the upper part of the body. The driving wheel is the forward direction when the walking frame is behind. Before starting, the arm and the bucket rod hinge place and the movable arm hydraulic cylinder are in the horizontal state. The bucket is retracted and the angle of the arm is kept at 45.N lloo. The distance between the bucket and the ground is kept on the bad pavement on the 300~ 500 mm.. When driving, move the machine at low speed, do not change the direction suddenly. Do not cross the obstacle. If the more out of date, the work device should be reduced to the ground as close to the ground as possible, and slow the speed of driving. It is not allowed to cross the barrier that is over 10 degrees.
3) before turning and driving back, we must first confirm that there is no personnel or obstacles in the scope of the operation, and then the horn or the signal is given to warn people not to be close to the machine. The signalman must be set up in the dangerous area or in the area with bad sight.
4) when driving on a hillside, embankment, or steep slope, it may cause the machine to turn over or slip, so be careful and reduce the speed. When driving, the bucket should be about 200~ 300 mm from the ground. Do not reverse the downhill. When the excavator crosses the uplift or other obstacles, the working device should be close to the ground and drive slowly. The excavator is at the excavator. It is very dangerous to turn or cross a slope on a slope. It is necessary to go down to a flat place to complete these movements. It is strictly prohibited that the bucket is full of downhill turn, and if you have to turn on the slope, the application of the soil on the slope to build a platform to keep the machine at work. Do not travel over 350 of the slope.
5) do not drive at low speed on the snow covered ground. Do not start, stop, turn or turn around. After heavy snow, the shoulder and roadside objects are buried in the snow and are very careful when the snow is cleared.
6) when working in dangerous areas such as the shoulder or the edge of the cliff, the machine may be out of balance, so make the driving wheel behind the walking frame so that it can be retreated quickly in an emergency. Do not break the machine out of the machine in order to prevent the collapse of the machine. Do not dig deep under the machine, because the machine underneath. The ground may collapse, causing the machine to fall.
7) when working on a soft ground (especially after heavy snow, heavy rain or soft soil), be sure to be more careful. Avoid working near the edge of the cliff, outhanging or deep canals. If these places collapse, the machines will fall or turn over and cause serious casualty accidents.
8) when working in highly restricted areas, such as in tunnels, under bridges, under wires or in repair shops, be careful not to let foreign objects collide with arms and rods.
9) wear rubber sole shoes or leather shoes when working under high pressure cables. When the machine must work near the cable, the signalman should be set up to warn at any time. In case the working device meets the cable, the driver should not leave the cab. Do not let anyone close to the machine when working in the vicinity of the high voltage cable.
10) the machine should be parked as far as possible on the horizontal ground. If you have to stop on the slope, you should use a wedge to hold the track and insert the bucket into the ground. When parking on the road, a fence and a warning flag or a signal lamp are suspended on the machine to warn pedestrians, and the machines, flags and lights do not affect traffic.
11) the electrolyte contains sulphuric acid in the battery electrolyte. If it is splashed on the sulphuric acid, rinse with water immediately. The acid splash should be flushed with a large amount of water immediately and sent to the hospital in time. When the battery is overhauled, the battery should wear a goggle. The hydrogen produced by the battery can easily explode and easily ignite when it meets the spark or open fire. Before the storage battery is maintained, the battery must close before the battery is maintained. Close the engine, turn the start switch to the closed position. Avoid accidental contact with the battery junction column, tighten the battery cover, connect the connection column to the battery line firmly, the loose battery line will produce sparks and cause the explosion.
12) when the auxiliary cable is started, the goggles should be worn. When the other machine is started, two machines are not allowed to contact. When the auxiliary cable is connected, the positive (+) pole must be connected first. When disassembly is dismantled, the ground wire or the negative cable must be dismantled first.
(1) pole cable. If any tool is built between the positive (+) pole and the frame, it will produce sparks. It is very dangerous. Two machines are connected in parallel, the positive pole is connected to the positive pole, and the negative electrode is negative. The ground wire must be far away from the battery when the machine is connected to the machine frame to be started.
13) when pulling a machine, use a steel cable with sufficient strength. No machine that can be traced on the slope. People do not cross the traction cable or wire rope. After connecting with the traction machine, do not let anyone enter between the traction machine and the tractive machine. The connection between them is a straight line, and the wire between the traction steel cable and the body should be added to the machine. Block. It is forbidden to use light load traction hole to pull the machine.
14) when lifting heavy duty, a special lifting hook (such as a hook installed in a bucket) is required, and a steel cable is prohibited to be fixed on the bucket teeth or directly entangled in the boom or bucket. In the course of lifting heavy duty, the hoisting can not be manned and no one enters the working area. When the lifting is hoisted, the engine speed should be reduced, the lifting operation is slowly carried out to avoid exercises. The longitudinal bar changes suddenly. The rotation speed of the excavator is 3~4 times of the bicycle crane, so be very careful when turning. The driver forbid to leave the seat, prohibit the vertical or horizontal drag, and do not take back the bucket at will, and do not walk.
