SAFE OPERATION - 5 7. Do not open the radiator cap before the radiator has cooled down sufficiently First loosen the cap to the first stop and allow the system enough time to release the remaining pressure. Then loosen the cap completely. 7. Do not use the hooks on the roof of CAB for lifting the excavator. 5. MAINTENANCE Before doing maintenance work on the excavator, place the machine on a firm, flat and level surface, lower the attachments to the ground, stop the engine, release pressure trapped in the hydraulic system, lock all control levers and remove the key. When dismantling hydraulic parts, make sure that the hydraulic oil has cooled down sufficiently to avoid burns.
Start maintenance work carefully, e.g. loosen plug slowly so that oil will not squirt out. 1. Before doing work on the engine, the exhaust system, the radiator and the hydraulics, let the excavator cool down sufficiently. 2. Always turn off the engine when filling the fuel tank. Avoid spilling and over-filling of fuel. 3. Smoking is prohibited while refueling or handling the battery. Keep sparks and fire away from the fuel tank and battery. Flammable gases escape from the battery, especially during charging. 4. Do not use or charge a refillable type battery if the fluid level is below the LOWER (lower limit level) mark.
Otherwise, the battery component parts may prematurely deteriorate, which may shorten the battery's service life or cause an explosion. Check the fluid level regularly and add distilled water as required so that the fluid level is between the UPPER and LOWER levels. 5. Read and follow the directions "STARTING WITH AN AUXILIARY BATTERY" in "OPERATION OF THE ENGINE", when starting with an auxiliary battery. 6. Keep a first-aid box and a fire extinguisher at hand at all times. 8. To avoid short-circuiting the battery, always remove the ground cable first and attach the positive cable first. 9.
Oil under high pressure can penetrate the skin and may be harmful to your health if not treated immediately. 10.Leaking hydraulic fluid has enough pressure to penetrate the skin and cause serious injuries. Leakages from pin holes can be totally invisible. Do not use hands for checking for leaks. Always use a piece of wood or cardboard. It is strongly recommended that you use a face mask or eye protection. Should injuries occur with leaking hydraulic fluid, contact a doctor immediately. This fluid can cause gangrene or serious allergic reactions. 11.To avoid environmental damage from acid and heavy metals, dispose of the battery appropriately.
12.Observe all laws and regulations concerning the disposal of used oil, coolants, solvents, hydraulic fluids, battery acids and batteries. Max. drawbar pull at coupling hook 116.9 kN (11920 kgf) Max. vertical load at coupling hook 12.1 kN (1234 kgf)
