WE-601B WINDROW ELEAVTOR Daily Or 10 Hour Service Caterpillar

1. Check and service as required:

a. Engine oil level.

b. Engine coolant level and radiator.

c. Engine air cleaner.

d. Fuel level.

e. Wing, side and bottom blades.

f. General machine for leaks, loose bolts, loose connectors, etc.

2. Lubricate in accordance with the Lubrication Chart.

Checking The Engine Oil Level

Check the oil level before starting. Add oil, if necessary, to bring it to the proper level on the dipstick.

Checking The Engine Coolant Level And The Radiator

Show/hide table

AT OPERATING TEMPERATURE, ENGINE COOLANT IS HOT AND UNDER PRESSURE. STEAM CAN CAUSE PERSONAL INJURY. CHECK COOLANT LEVEL ONLY WHEN ENGINE IS STOPPED AND FILLER CAP IS COOL ENOUGH TO TOUCH WITH YOUR HAND. REMOVE THE FILLER CAP SLOWLY TO RELIEVE PRESSURE.

1. Slowly, turn the pressure cap to the first stop and release pressure.

2. Push the cap down and turn until the cap is released.

3. Maintain the coolant level to within 2 inches (5.1 cm) of the base of the fillpipe. Never add coolant to an overheated engine; allow it to cool first.

4. Check the radiator for any obstructions to air flow such as leaves, rags, etc.

Checking The Engine Air Cleaner

The engine air cleaner is equipped with an indicator that shows a red signal when the main element should be serviced. If the red signal is locked in view, the main element should be serviced as soon as possible to prevent possible engine damage. See "Changing the Air Cleaner Element" below for procedures.

Changing The Air Cleaner Element

The main element should be replaced after six cleanings or one year of use, whichever occurs first. Change the safety element every third time the main element is cleaned or replaced. Although it is possible to clean the safety element using the procedures described for the main element, it is not recommended except in an emergency situation. Maximum engine protection is achieved by replacing the plugged safety element with a new element.

Replacing The Main Element

Show/hide table

INADVERTENT STARTING OF THE ENGINE COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN AND REMOVE THE KEY FROM THE IGNITION SWITCH.

1. STOP THE ENGINE, remove the cover assembly and clean it.

2. Remove the main element. DO NOT REMOVE THE SAFETY ELEMENT.

3. Immediately inspect the main element for any dust streaks on the inside. If there are any dust streaks, the element is damaged, THROW IT AWAY.

4. Inspect the main element gasket. If the element gasket is not smooth and flat or is damaged in any way that might allow dust to get by, THROW THE ELEMENT AWAY.

5. Install a new or cleaned main element.

6. Inspect the gasket washer on the wing nut and replace it if a good air seal cannot be guaranteed.

7. Tighten the wing nut securely.

8. Install the cover assembly.

9. Inspect the dust ejection valve for damage. Be sure the valve is securely in place and is not inverted.

Replacing The Safety Element

Show/hide table

INADVERTENT STARTING OF THE ENGINE COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN AND REMOVE THE KEY FROM THE IGNITION SWITCH.

1. STOP THE ENGINE, remove the cover assembly and clean it.

2. Remove the main element.

3. Remove the safety element and clean out any dust dislodged into the cleaner outlet.

4. Install the new safety element.

5. Inspect the gasket washer on the wing nut and replace it if a good air seal cannot be guaranteed.

6. Tighten the wing nut securely.

7. Install the main element and tighten the wing nut securely.

8. Install the cover assembly.

Cleaning The Engine Air Cleaner Main Element

The dirty air cleaner element can be cleaned by one of three methods: (1) washing in a solution of water and detergent, (2) blowing with compressed air, or (3) washing with water alone. Detergent and water are best when the element is loaded with a combination of exhaust carbon, soot, oil and dust. Compressed air is effective when the element is loaded with dust. Washing with water alone will often work when air is not available and the element has only dust on it. Whichever method of cleaning is used, the element should be handled carefully to keep it from being punctured or dented. DO NOT ATTEMPT TO CLEAN THE ELEMENT BY BEATING OR RAPPING IT. The main element, protected by steel lines, is strong enough to take normal handling, but it will not stand an unlimited amount of abuse. DO NOT USE GASOLINE OR OTHER VOLATILE SOLVENTS TO CLEAN ELEMENTS. The element or the engine could be damaged.

Cleaning with Detergent and Water

Show/hide table

COMPRESSED AIR CAN CAUSE PERSONAL INJURY. WEAR EYE PROTECTION, LONG SLEEVES AND GLOVES. NEVER USE MORE THAN 30 PSI (207 kPa) AIR PRESSURE.

1. If compressed air is available, remove the loose dust by blowing from the inside of the element. Use less than 30 psi (207 kPa), keep the nozzle at least one inch (2.54 cm) away from the element, and blow on the inside only. If compressed air is not available, run water through the element from the inside. Use a gentle water stream, less than 40 psi (276 kPa).

2. Soak the element in a solution of water and detergent.

3. Gently swish the element around the solution to help loosen the dirt.

4. With a gentle stream of water, less than 40 psi (276 kPa), rinse the entire element until the water comes through the element clear. Good rinsing is important.

5. Dry the element thoroughly before inspecting it. Mechanical dryers can be used, but heated air must be circulated and must be less than 160°F (71°C). DO NOT USE A LIGHT BULB TO DRY THE ELEMENT.

Cleaning with Air Only

Show/hide table

COMPRESSED AIR CAN CAUSE PERSONAL INJURY. WEAR EYE PROTECTION, LONG SLEEVES AND GLOVES. NEVER USE MORE THAN 30 psi (207 kPa) AIR PRESSURE.

1. Direct a jet of compressed air against the inside of the element. To prevent possible personal injury and damage to the filter medium, use less than 30 psi (207 kPa), and keep the nozzle at least one inch (2.54 cm) away from the medium.

2. Move the nozzle up and down each pleat, continuing until no more dust is being removed. Do not blow air against the outside of the element because this will merely force the dirt farther into the pleats.

Cleaning with Water Only

1. Run water through the element from the inside only. Use a gentle stream of water, less than 40 psi (276 kPa).

2. Run water through the element until the water comes through clear.

3. Dry the element thoroughly before inspecting it. Mechanical dryers can be used, but heated air must be circulated and must be less than 160°F (71°C). DO NOT USE A LIGHT BULB TO DRY THE ELEMENT.

Inspection After Cleaning

1. After cleaning and drying the element, inspect it for a damaged gasket, a ruptured filter medium or dust on the inside of the element. If the gasket's condition is such that a good air seal cannot be guaranteed, or if the filter medium is ruptured, discard the element and replace it with a new one of the same model. Proper sealing of the element gasket is important.

2. A good method to detect filter medium ruptures is to place a bright light inside the element. Inspection of the element from the outside will then disclose, by a bright spot of light, any holes or ruptures. Any hole in the element will allow dust to enter the engine.

Service Hints

1. Store new and cleaned spare filter elements so they are protected from dust and potential damage.

2. When replacing a filter element, be sure the correct size and model element is used.

3. Replace the main element after one year or after six cleanings whichever occurs first.

4. Keep a spare element (new or cleaned) on hand to reduce vehicle down-time for servicing.

5. This is a dry type air cleaner, DO NOT USE OIL.

6. Do not operate the air cleaner without both the main and safety elements installed.

7. If excessive dust is found in the air transfer duct or the engine intake system, check the following: connections between air cleaner outlet and engine; air cleaner outlet to body joint for leaks; element gasket washers and element gasket; and element medium for holes, cracks or breaks.

8. DO NOT ATTEMPT TO CLEAN ELEMENTS BY BEATING OR RAPPING.

Checking The Fuel Level

Show/hide table

DIESEL FUEL IS VOLATILE AND COULD IGNITE OR EXPLODE, CAUSING SERIOUS BURNS AND INJURIES FROM FLYING OBJECTS. NEVER SMOKE OR HAVE AN OPEN FLAME WHILE WORKING ON THE FUEL SYSTEM.

Visually check the fuel level after removing the fill cap. Keep the fuel tank filled to reduce condensation. Be sure to fill the fuel tank at the end of the day to reduce condensation caused by the tank cooling off during the night.

Checking The Wing, Side And Bottom Blades

The blades should be checked for excessive wear and for loose connecting bolts. Tighten any loose bolts and replace blades as necessary.
