Operation in Extreme Conditions
Operation In Extreme Cold
In extremely cold weather, avoid sudden travel movements and
stay away from even slight slopes. The machine could slide
down the slope.
Snow accumulation could hide potential hazards and slippery
surfaces.
Warming up engine for a short period may be necessary to avoid
operating with sluggish or reduced working capacity. The jolting
shocks and impact loads caused by bumping or bottoming boom or
attachment could cause severe stress in very cold temperatures.
Reducing work cycle rate and workload may be necessary.
If machine is to be operated in extremely cold weather
temperatures, certain precautions must be taken. The following
paragraphs detail checks to be made to be certain machine is
capable of operating at these temperatures.
1.
Keep batteries fully charged to prevent freezing. If distilled
water is added to batteries, run engine at least one hour to
mix electrolyte solution.
When temperature drops below -10°C, efficacy of the
battery is reduced accordingly. Insulation of the battery
prevents reduction of efficacy, and supports improvement
of starting power of the starter.
2.
Keep engine in good mechanical condition for easy starting
and good performance during adverse weather.
3.
Use engine oil with proper specifications for expected
temperatures. Refer to "Table of Recommended Lubricants"
on page 4-19, in this manual or Shop Manual for details.
4.
Always keep the fuel tank fully filled after completion of the
operation. Always drain water from the fuel tank before and
after the operation. In addition, check the water separator,
and drain it if required. The fuel filter, if frozen, may interrupt
the flow of fuel. Periodically remove water from the fuel tank,
drain water from the filter, and replace the filter upon regular
basis. To prevent fuel from being clogged because of
formation of wax in fuel, make sure that wax formation point
of fuel is lower than atmospheric temperature.
WARNING
AVOID DEATH OR SERIOUS INJURY
Explosion of the battery can cause death or serious injury.
Never attempt to directly heat the battery with open fire.
