Cooling System
| NOTICE |
|---|
Never add coolant to an overheated engine. Allow the engine to cool first. To ensure adequate freeze protection in cold weather, measure the specific gravity of antifreeze solution frequently. When permanent-type antifreeze and water solutions are used in the cooling system, drain and replace the solution Every 2,000 Service Hours or Yearly. When additions of cooling system conditioner are made as recommended, the drain and refill period can be extended to Every 4,000 Service Hours or Two Years. Regardless of the concentration of antifreeze, the cooling system should contain a 3% to 6% concentration of conditioner at all times. Do not use AVSpare Cooling System Conditioner with Dowtherm 209 Full-Fill. Follow the recommendations provided with the Dowtherm 209 Full-Fill. If the machine is shipped to or stored in an area with freezing temperatures, the cooling system must either be protected to the lowest expected outside temperature or drained completely. |
Pure undiluted antifreeze will freeze at -23°C (-10°F).
The engine cooling system is protected to -29°C (-20°F) with permanent-type antifreeze when shipped from the factory.
Use clean water that is low in scale forming minerals - not softened water.
When refilling the cooling system, operate the engine with the radiator cap off. When the engine reaches normal operating temperature, check the coolant level.
Filling the cooling system at over a 19 liter/min (5 gpm) rate can cause air pockets in the cooling system.
When measuring the coolant level, inspect the fill cap gasket. Replace the cap if the gasket is damaged.
Premix antifreeze solution to provide protection to the lowest expected outside temperature.
Cooling system problems can develop without a thermostat. Operate with a thermostat in the cooling system at all times.
Engine Air Cleaner
When the engine air cleaner indicator light goes on, service the air cleaner.
Inspect the air precleaner cup daily for accumulation of dust and debris.
Fuel System
To drive out moisture laden air, fill the fuel tank at the end of each day of operation.
Measure the fuel level with the dipstick in the fill opening.
Drain moisture and sediment from the fuel tank as required by prevailing conditions. Always drain moisture and sediment at the start of each shift, or after the tank has been filled and allowed to stand 5 to 10 minutes.
Drain water and sediment from the main fuel storage tank weekly. Also, drain the tank before it is refilled. This will help prevent water and sediment from being pumped into the machine fuel tank.
Accumulated grease and oil on a machine is a fire hazard. Remove this debris with steam cleaning or high pressure water at least every 1,000 service hours, or any time a large quantity of oil is spilled on the machine.
To prevent tanks from being hit by equipment when fueling, have job site fuel storage tanks protected by an embankment or steel posts.
When draining oil, collect drained oil and wipe up spills.
Loose or damaged lines, tubes or hoses, which leak, can cause fires:
Do not bend or strike high pressure lines. Do not install bent or damaged lines.
Inspect all lines, tubes and hoses carefully. Tighten all connections to the recommended torque.
To prevent vibration, rubbing against other parts, or excessive heat during operation, make sure that all clamps, guards and heat shields are installed correctly.
Shields which protect hot exhaust system components from oil or fuel spray must be installed correctly. This will help prevent fires in the event of a line, hose or seal failure.
Electrical System
| NOTICE |
|---|
Turn the disconnect switch off and remove the key, before attaching the cable to the emergency starting receptacle when using an external electrical source to start the machine. Be sure to connect in parallel: POSITIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-), when using booster cables). |
Hydraulic System
| NOTICE |
|---|
Make-up hydraulic fluid must mix with the fluid in the tank. Use only petroleum products unless the machine is equipped for use with special products. Hydraulic pump failure can be caused by water or air in the hydraulic system. |
If the hydraulic oil is cloudy, water or air is entering the system. Purge and refill the system. Consult your AVSpare dealer for the correct purging instructions.
Tighten the suction hose clamps and flanges.
Scheduled Oil Sampling
Use scheduled oil sampling to monitor machine condition and maintenance requirements.
The oil should be hot, and well mixed, when each sample is taken. This will ensure that the sample is representative of the oil in the compartment.
Consult your AVSpare dealer for complete information and assistance in establishing a scheduled oil sampling program for your equipment.
