1. Introduction

This manual provides comprehensive instructions for the proper installation, function, and care of your MAKO AIRTEK Fuse Box Cover.

Please read this manual thoroughly before installation and use to ensure optimal performance and safety.

2. Safety Information

• Always disconnect the vehicle's battery before performing any electrical work to prevent electrical shock or damage to components.

3. Installation

3.1 Pre-Installation Check

1. Verify that the new MAKO AIRTEK Fuse Box Cover matches the original cover in size and mounting points.
2. Inspect the new cover for any signs of damage from shipping.
3. Ensure the fuse box housing on the excavator is clean and free of dirt or moisture.

3.2 Installation Steps

1. Disconnect Power: Before beginning, ensure the excavator's main power is turned off and the battery is disconnected to prevent accidental electrical shorts.
2. Remove Old Cover: Carefully unclip or unscrew the existing fuse box cover from its housing. Note its orientation.
3. Clean Area: Clean any dirt or debris from around the fuse box housing to ensure a good seal for the new cover.
4. Position New Cover: Align the MAKO AIRTEK Fuse Box Cover with the fuse box housing. Ensure the mounting tabs or clips are correctly positioned.
5. Secure Cover: Gently press down or clip the new cover into place until it is securely fastened. It should sit flush with the housing.
6. Reconnect Power: Once the cover is securely installed, reconnect the vehicle's battery and restore power.
7. Functionality Check: Start the excavator and check that all electrical systems (lights, radio, wipers, etc.) are functioning correctly.

The top part is the protective lid, and the bottom part shows the internal layout with labels for various fuses and their amperage ratings, such as CHAS LAMP, BOOM LAMP, RADIO, HORN, WIPER, WASHER, and others, along with their respective amperage values (e.g., 10A, 15A, 20A).

4. Operation

The fuse box cover serves as a protective barrier for the electrical fuses and relays within your Caterpillar excavator. It also provides a clear diagram indicating the function and amperage rating of each fuse. Refer to the diagram on the inside of the cover (as shown in Figure 1) for quick identification of specific circuits.

Note: Always replace a blown fuse with a new fuse of the exact same amperage rating to prevent electrical damage or fire. Using a fuse with a higher rating can lead to serious electrical issues.

5. Maintenance

5.1 Cleaning

• Periodically clean the exterior of the fuse box cover with a damp cloth to remove dirt and grime.
• Ensure no moisture enters the fuse box during cleaning.
• Avoid using harsh chemicals or abrasive cleaners that could damage the plastic or fade the labels.

5.2 Inspection

• Regularly inspect the fuse box cover for cracks, damage, or signs of wear that could compromise its protective function.
• Ensure the cover remains securely latched or screwed down to prevent water and dust ingress.
• Check the fuse diagram for legibility. If it becomes unreadable, consider replacing the cover or marking the functions clearly.

6. Troubleshooting

6.1 Common Issues

• Cover does not fit: Double-check the model compatibility with your excavator. Ensure no obstructions are preventing proper seating.
• Cover is loose: Verify that all clips or screws are properly engaged and tightened. If the cover is damaged, it may need replacement.
• Electrical component not working: This is likely due to a blown fuse. Refer to the fuse diagram on the cover to identify the correct fuse for the affected component. Disconnect power, remove the old fuse, and replace it with a new fuse of the identical amperage rating. If the new fuse blows immediately, there may be a short circuit in the system, requiring professional diagnosis.
