Lubricating Oils

Use Superior Lubricants (Series 3), MIL-L-2104A or MIL-L-2104B oil as specified

Lubricating Grease

Use NLGI No. 2 Grade Multipurpose-type Grease for most temperatures. For extremely low temperatures, use NLGI No. 0 or No. 1 Grade.

Diesel Fuel

Use only distillate fuels (No. 2 fuel oil or No. 2-D diesel fuel) with a minimum cetane number of 35.

See your AVSpare dealer for information regarding fuels marketed in your area.

Fill diesel fuel tank at the end of each day of operation to drive out moisture laden air and prevent condensation.

Check fuel level with plunger gauge in the filler opening.

Hydraulic System

Use Superior Lubricants (Series 3) oil containing Zinc Dithiophosphate or oil meeting MIL-L-2104A or MIL-L-2104B specifications.

* ALWAYS lower raised equipment or install lift arm support bracket before servicing hydraulic system.

* MOVE hydraulic controls to relieve any hydraulic pressure before servicing hydraulic system

Cooling System

* Use clean water that is free of scale forming minerals.
* Add AVSpare Rust Inhibitor to prevent rust.
* Rust inhibitor is not required when using permanent-type anti-freeze containing rust inhibitors.
* Never add coolant to an overheated engine. Allow engine to cool first.

* TO DRAIN - coolant should be warm and machine level

* CHECK specific gravity of anti-freeze solution frequently - to assure adequate protection.

Air Cleaner Elements

* Do not clean elements by bumping, tapping or jarring.
* Have spare elements to use while cleaning and drying used elements

Cleaning with Pressure Air

1. Use CLEAN, DRY air - 100 PSI max

2. DIRECT air inside element along length of pleats

3. DIRECT air outside element along length of pleats

4. DIRECT air inside element along length of pleats

5. WRAP and STORE in DRY, CLEAN place

Cleaning with Water

1. Use CLEAN water - 40 PSI max

2. DIRECT water inside element - along length of pleats

3. DIRECT water outside element - along length of pleats

4. RINSE inside element

5. Air DRY thoroughly

6. WRAP and STORE in DRY, CLEAN place

Cleaning with Detergent

1. WASH in warm water and non-sudsing household detergent

2. RINSE with CLEAN water (40 PSI max.) direct inside - along length of pleats

3. DIRECT water outside element along length of pleats

4. RINSE inside element

5. Air DRY thoroughly

6. WRAP and STORE in DRY, CLEAN place

Checking Element

1. INSERT light inside element

2. CHECK for pin holes and tears in element

Glow Plugs

* Locate defective glow plugs by checking ammeter reading. Each glow plug draws approximately 5 amps.

1. TURN switch to HEAT

2. CHECK ammeter

3. RELEASE switch

4. REMOVE glow plug lead

5. TURN switch to HEAT to CHECK draw

5A. NO CHANGE - defective plug

5B. CHANGE - good plug

6. CHECK remaining plugs - one at a time

7. REMOVE defective plugs

8. APPLY Anti-Seize Compound (Part No. 9M3710) to threads of new glow plugs

9. INSTALL new glow plugs Tighten to 10-12 lb. ft. (1,38 to 1,66 mkg)

10. CONNECT leads

Wiring Diagram - 24 Volt System

Bucket Teeth - To Replace

1. DRIVE pin out

2. SLIDE tip off

3. POSITION plug

4. SELECT tip position

5. SLIDE tip over adapter to align pin holes

6. INSTALL pin

7. TIGHTEN to 265 ± 35 lb. ft. (36 ± 4 mkg)

Ripper Teeth - To Replace

1. DRIVE pin out

2. SLIDE tip off

3. POSITION plug

4. SELECT tip position

5. SLIDE tip over shank to align pin holes

6. INSTALL pin

Servicing Hints

Wipe fittings, caps and plugs before servicing

Clean covers and guards before removing

Clean drain plugs before installing
