Bucket Tips

Change the Bucket Tips

------ WARNING! ------

Retainer pins, when struck with force, can fly out and cause injury to nearby people.

Make sure the area is clear of people when driving retainer pins.

To avoid injury to your eyes, wear protective glasses when striking a retainer pin.


Replace the bucket tip when worn close to shank.

1. Raise and support the bucket.
2. Drive the pin out from the tip. Remove the pin retainer and the tip.
3. Clean the shank pin retainer and pin.

2. Fill with window washer solvent.
3. Install the fill cap.

Engine Air Intake

Change the Filter Elements

------ WARNING! ------

Pressure air can cause personal injury.

When using pressure air for cleaning, wear a protective face shield, protective clothing and protective shoes.



Service the air cleaner only with the engine stopped.

Change the air filters when the indicator shows red or the exhaust smoke is black.

Graduated lines on the indicator show approximately when elements will need replacing.

Change the Primary Filter Element

1. Remove the filter element cover.

2. Remove the primary filter element.
3. Clean the inside of the air cleaner housing with a clean cloth.
4. Clean the primary filter element. See "Cleaning Primary Filter Elements."

5. Install a clean primary filter element.

6. Install the cover. Tighten the retaining bolt finger tight. Do not use a tool to tighten the bolt.

7. Reset the filter indicator by pushing in the reset button.
8. Start the engine.

If the indicator shows red, or the exhaust smoke is still black after installation of a primary filter element that has been cleaned six times, change to another clean filter element.

The filter element can be cleaned a maximum of six times. Replace the primary element after it has been cleaned six times or at least once a year.

If the indicator shows red shortly after installation of a clean primary filter element, change the secondary filter element.

Change Secondary Filter Element


Always replace the secondary filter element. Never attempt to reuse it by cleaning.

The secondary filter element should be replaced at the time the primary element is serviced for the third time.

The secondary filter element should also be replaced if the indicator shows red after installation of a clean primary element, or if the exhaust smoke is still black.

1. Remove the cover and the primary filter element.
2. Clean the inside of the housing.

3. Remove the retainer that holds the secondary filter element to the housing. Remove the filter element.

4. Install a new secondary filter element and retainer.

5. Install the primary filter element and the cover. Tighten the cover bolts finger tight only.

6. Push the filter indicator reset button in.

Cleaning Primary Filter Elements


Do not clean the filter elements by bumping or tapping them.

Inspect the filter elements after cleaning. Do not use a filter element with damaged pleats, gaskets or seals.

When cleaning with pressure air, use 205 kPa (30 psi) maximum pressure to prevent filter element damage.

Typical Examples Shown

When cleaning with pressure water, use 280 kPa (40 psi) maximum pressure to prevent filter element damage.

Filter elements can be cleaned with pressure air, pressure water, or detergent.

Pressure Air - 205 kPa (30 psi) Maximum

1. Direct air along pleats inside and outside of filter element. Direct air along pleats inside of filter element.
2. Inspect the filter element after cleaning.

Pressure Water - 280 kPa (40 psi) Maximum

1. Direct the water along the inside and outside of the pleats.
2. Air dry and inspect the element.


1. Wash the filter element in warm water and nonsudsing household detergent.
2. Rinse thoroughly with clean water, air dry and inspect the filter element.

Inspect the Filter Element

1. Insert a light inside a dry and cleaned filter element. Discard any filter element with rips or tears.

2. Wrap and store the clean filter elements in a clean, dry place.

Cooling System Relief Cap - Perkins Engine

Replace When Faulty

------ WARNING! ------

At operating temperature, the engine coolant is hot and under pressure.

Steam can cause personal injury.

Check the coolant level only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand.

Remove the fill cap slowly to relieve pressure.

Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to prevent personal injury.


Remove the access cover.

1. Remove the coolant fill cap slowly to relieve pressure.

NOTE: Radiator cap location could be on top, depending on which machine you have.

2. Replace the fill cap when the cooling system does not maintain pressure or coolant loss is noticed.

3. Install the coolant fill cap.
4. Install the access cover.


Inflation - Nitrogen

1. Measure the tire pressure of each tire.

------ WARNING! ------

Use a self-attaching air chuck and stand behind the tire tread while inflating the tire to prevent personal injury if tire or wheel compnents come loose.

2. Inflate the tires, if necessary. See "Tire Inflation Information."

Tire Pressures

The inflation pressures shown in the chart below are cold inflation operating and shipping pressures for tires on AVSpare machines.

The inflation pressure is based on the weight of a ready-to-work machine without attachments, at rated payload, and in average operating conditions. Pressures for each application may need to be varied from those shown and should always be obtained from your tire supplier.

Emergency Inflation

------ WARNING! ------

Do not open door while engine is running. Personal injury could result from contact with moving parts.


1. Remove the inflation hose from the tool box. Open the access door.

2. Remove the dust cap and install the hose to valve connector.

3. Install the self-attaching air chuck and inflate as needed.
4. Remove hose and install dust cap and access cover.

Antifreeze Pump - Air Tank

Fill the Pump

------ WARNING! ------

Removal of filler plug can release air and alcohol under pressure resulting in possible injury. Remove slowly to allow pressure to release.


Injection pump prevents freezing and icing in the air tanks.

1. Raise the access cover.

2. Push the valve (1) down against the stop and turn 90° and lock.
3. Remove the fill plug/dipstick (2).
4. Add ethyl alcohol as the antifreeze, up to the top mark on the dipstick.
5. Install the fill plug/dipstick.

Antifreeze Summer and Refilling Position

1. Turn the handle 90° and pull up.

Use this position during cold weather 5°C (40°F) or below.

2. Push the handle down and turn 90°.

Use this position for above 5°C (40°F) or when adding the antifreeze.
