2.8 Special conditions to use the machine
2.8.2 Climatic conditions
Operating the machine at low temperatures
Prepare the machine for operation at low temperatures:
• Replace the engine oil with the oil recommended for the
range of ambient temperatures.
• Use hydraulic oil of the corresponding cinematic viscosity.
• Use a winter diesel.
• Check the battery for charging.
Operation at low temperatures:
• The good condition of the battery is a precondition for good
starting under low temperatures. The machine can be used
at full power only after the operating fluids have been heat-
ed to their operating temperatures.
• Every week check all rubber parts, e.g. hoses, V-belts.
• Check all electrical cables and connections for worn and/or
damaged insulation.
• Refill the fuel tank at the end of every shift.
Operating the machine at higher temperature and humidity:
• The engine power output decreases with the increasing
temperature and air humidity. Considering that both of the
factors reducing the engine power are independent on each
other, it is possible to describe their impact as follows:
- Every 10 °C (18 °F) of the temperature rise means a pow-
er drop by up to 4% (at a constant humidity).
- Every 10 % of the relative humidity rise means a power
drop by up to 2% (at a constant temperature).
• At outdoor temperatures when the hydraulic oil tempera-
ture is constantly about 90°C (194°F), we recommend you to
replace the oil with the oil ISO VG 100 having the cinematic
viscosity of 100 mm
2
/s at 40°C (104°F).
Machine operation at high altitudes
• With the increasing altitude, the engine power output de-
creases as a result of the lower atmospheric pressure and
specific density of the incoming air.
The engine power depends on the environment, in which
the machine is working.
2.8.3 Operation of the machine in dusty
environment
While operating in a very dusty environment, shorten clean-
ing and replacement intervals of air filter cartridges and
shorten cleaning intervals of coolers.
The recommended cleaning interval is once a week.
