ENGINE AR-PRIM 20R0350 - Caterpillar

Cooling
Always check system with engine off. Remove filler cap slowly to relieve pressure, steam may cause personal injury.
Inhibitor contains alkali, avoid contact with skin and eyes.
Never add coolant to an overheated engine, allow engine to cool first.
Check specific gravity of antifreeze solution frequently in cold weather to assure adequate protection.
When permanent antifreeze and water solutions are used in the cooling system, the solution should be drained and replaced every 2000 hours, or yearly. However, when additions of inhibitor are made to the cooling system every 500 hours, or three months, it is not necessary to drain and refill yearly. An antifreeze solution providing protection to at least -20°F (-29°C) must be used to provide corrosion protection.
If machine is to be stored in, or shipped to, an area with below freezing temperatures, the cooling system must be drained completely, or protected to lowest expected ambient temperature.
The engine cooling system is protected to -20°F (-29°C), with permanent-type antifreeze, when shipped from the factory.Use clean water that is low in scale forming minerals, not softened water. Add Caterpillar Corrosion Inhibitor or equivalent to provide corrosion protection. Follow recommendations given on container.Whenever draining and refilling cooling system, always recheck the coolant level when the engine reaches normal operating temperature.Filling at over 5 gal. (3.8 liters) per minute rate can cause air pockets in the cooling system.Premix antifreeze solution to provide protection to the lowest expected ambient temperature. Pure undiluted antifreeze will freeze at -10°F (-23°C).Operate with a thermostat in the cooling system all year round. Cooling system problems can arise without a thermostat.Fuel
Fumes from fuel are flammable. Do not smoke while refueling.
Fill fuel tank at the end of each day of operation to drive out moisture laden air and to prevent condensation. Don't fill the tank to the brim. The fuel expands when it gets warm and may overflow.
Check fuel level with dipstick in filler opening.Drain fuel tank of moisture and sediment as required by prevailing conditions.After changing fuel filters, always bleed fuel system to remove air bubbles from system.Air Intake
Check precleaner screen daily for accumulation of dust and debris.Service air cleaners when RED band in indicator locks in visible position.General
Batteries give off flammable fumes. Do not smoke when checking battery electrolyte level.
If track is sealed and lubricated type, secure track with chain before separating links. Sealed and lubricated track is very flexible. When disconnected it can move and cause injury.
To prevent personal injury always lower all equipment, stop engine, set parking brake and block or restrain machine before servicing it.
If engine is not running, do not release emergency or parking brake systems unless machine is blocked or restrained.
Whenever draining lubricant extreme caution should be used, lubricant may be hot and can cause personal injury.
Track should be run as loose as possible in actual working conditions. If packing is occurring (material between bushing O.D. and sprocket tooth), track sag should be 11/2 to 2 inches (40 to 50 mm) with the packed material present.Drain moisture and sediment from air reservoirs at the
