3.8 UNUSUAL OPERATING CONDITIONS.
Special problems in maintenance and operation are caused by unusual conditions such as extremes in heat, cold and
humidity, high altitude, salt water, and dusty or sandy work sites. When operating under such conditions, special
precautions must be taken to prevent machine damage, minimize wear, and avoid component deterioration.
EXTREME COLD.
1.
Condensation in the fuel tank contaminates the fuel supply with water, which can freeze in the fuel lines and block
the fuel flow to the engine. To minimize this possibility, keep the tank as full as is practical during cold weather. This
may entail refilling the tank more frequently than usual, but the inconvenience is small compared to clearing a
blocked fuel line.
If water should be noticed in the fuel supply, drain the tank and refill it with uncontaminated fuel.
2.
Lubricate the machine with the lubricants recommended for cold weather operation in the Lubrication Section. If
necessary, change the engine oil and other lubricants in order to conform to the recommendations.
3.
The battery is probably the most sensible element to low temperatures. Freezing temperatures of battery electrolyte
is as higher as the more discharged battery. When this can occurs, be sure that battery is always charged, mainly
when you know that the machine has not been working for a long time. Further, battery would discharge also when
terminals should be covered by ice or snow, by causing a short-circuit. Keep dried both terminals and clamps. Keep
away an eventual beginning of corrosion, by using water and sodium carbonate. In case of a long working stop at
very low temperatures, is advisable to remove battery, by keeping it in a sheltered place.
4.
Special attention must be given to the hydraulic oil during very cold weather.
5.
At the end of the work period, or whenever the machine is to be left idle for extended periods, prevent it from being
frozen to the ground by parking it on wood, concrete, asphalt or mat surface.
EXTREME HEAT.
Like extreme cold, extreme heat requires that precautions be taken with respect to the cooling system, the battery and
lubrication. Protect the machine by performing the following recommended procedures.
1.
High temperatures necessitate the use of lubricants which are both more viscous and which resist deterioration at
higher operating temperatures. Refer to the Lubrication Section and lubricate the machine using the lubricants
recommended for the expected temperatures.
Crankcase oil is particularly important because it helps dissipate heat. Check the oil level frequently and add oil as
required to maintain required level. Too little oil will hinder heat dissipation.
2. Increased evaporation rates will cause the battery electrolyte level to fall more rapidly during very hot weather.
Check the level frequently and add distilled water as required to maintain the proper level.
3. Air circulation around the engine and battery must not be restricted. Keep air intake and exhaust openings clear of
leaves, paper or other foreign matter which may restrict air flow.
4. Keep the engine clean of dirt. grease and other substance s which inhibit heat dissipation.
5. Avoid prolonged periods at idle and shut the engine down if operations are interrupted.
