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. Turn off the engine at all times when filling with fuel.
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
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.

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.
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
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.
