SAFE OPERATION (1) Groove (1) Battery Do not attempt to mount a tire on a rim. This should be done by a qualified person with the proper equipment. Always maintain the correct tire pressure. Do not inflate tires above the recommended pressure shown in the operator's manual. SERVICING THE TRACTOR Before servicing the tractor, park it on a firm, flat and level surface, set both parking brakes, lower all implements to the ground, place the gear shift lever in neutral, stop the engine and remove the key. Allow the tractor time to cool off before working on or near the engine, muffler, radiator and so on. Do not remove radiator cap while the coolant is hot.
When cool, slowly rotate cap to the first stop and allow sufficient time for excess pressure to escape before removing the cap completely. If the tractor has a coolant recovery tank, add coolant or water to the recovery tank, not the radiator. (See Checking coolant level on page 107.) Always stop the engine before refueling. Avoid spills and overfilling. Use only approved fuels. Always use grounded refueling facilities. Do not smoke when working around the battery or when refueling. Keep all sparks and flames away from battery and fuel tank. The battery presents an explosive hazard because it gives off hydrogen and oxygen especially when recharging.
Before “jump-starting” a dead battery, read and follow all of the instructions. (See JUMP STARTING on page 43.) Keep first aid kit and fire extinguisher handy at all times. Disconnect the battery's ground cable before working on or near electric components. To avoid the possibility of battery explosion, do not use or charge the refillable type battery if the fluid level is below the [LOWER] (lower limit level) mark. Check the fluid level regularly and add distilled water as required so that the fluid level is between the [UPPER] and [LOWER] levels. To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable (-) first and reconnect it last.
Securely support the tractor when either changing wheels or adjusting the wheel tread width. Make sure that wheel bolts have been tightened to the specified torque. Disconnect the battery's ground cable and stop the engine to avoid the possibility of the machine runaway due to 4WD braking system during testing, service or repair with only rear wheels off the ground. Do not work under any hydraulically supported devices. They can settle, suddenly leak down, or be accidentally lowered. If it is necessary to work under the tractor or any machine elements for servicing or adjustment, securely support them with stands or suitable blocking beforehand.
Escaping hydraulic fluid under pressure has sufficient force to penetrate the skin, causing serious personal injury. Before disconnecting hydraulic lines, be sure to release all residual pressure. Before applying pressure to the hydraulic system, make sure that all connections are tight and that all lines, pipes, and hoses are free of damage. M5091N, M5101N 11
