4.1 Before Starting the Engine
4.1.1 Routine checks
Before starting the engine, it is necessary to
inspect your machine carefully and completely.
Check for any loose bolts or nuts. Check for
any leaks of oil, fuel or coolant. Check the con-
ditions of the work equipment and hydraulic
system. It is also necessary to check for loose
wires, any spaces or dust buildup at where it
is close to high temperature.
Remove flammable materials from the sur-
rounding of battery, engine, muffler, turbo-
charger, or other hot components. The leak of
oil or fuel may cause the machine to catch on
fire. Careful inspection is necessary. Contact
your Sany distributor if any fault of your ma-
chine must be corrected.
Check and clean the following items each day
before starting the engine:
1. Check the work equipment, cylinders, arms
and hoses for cracks, excessive wear or
loosening. Repair it in case of any problem.
2. Remove the dirt and debris around the
engine, battery and radiator.
Check the surrounding of engine and ra-
diator for buildup of dirt. Check the sur-
rounding of muf
fl
er, turbo charger or other
hot components for flammable materials
like dry leaves and thin branches. Remove
them if any dirt or
fl
ammable materials are
found.
