Try These Attachment Maintenance Tips for Maximum Performance

Investing in the right attachments for a single machine can help you get more done on jobs that would normally require an entire fleet. Preventive maintenance with hydromechanical attachments is especially important because these tools are powered by auxiliary flow from the machine. Here are a few attachment maintenance tips to keep our most commonly used hydromechanical equipment running at maximum performance.

1. Power Box Rakes

Daily Maintenance | Tighten any loose hardware. Inspect tires and rims. Elevate tires off the ground and check for excessive wear on tire bearings or axles by moving wheels side-to-side.

Weekly Maintenance | Ensure tire pressure is maintained at 60 psi. Low pressure can cause the tire to detach at the rim. Every week or after 10 hours of service, lubricate the pivot plate and bolt, caster mount brackets, and roller bearings. Keep lubricant levels even with lubricant level hole. If necessary, add fluid gear grease through the filter plug hole.

2. Angel Brooms

Operational Tips | Avoid premature wear of the bristles by adjusting the broom bristles so they are gently in contact with the pavement.

Daily Maintenance | Look for uneven wear, premature breaking, or loss of bristles. Be sure fasteners are tight, pivot points are in good condition, and the chain is adjusted properly, according to instructions in the angle broom operation manual. Lubricate the outer and inner bearing on the bristle side of the broom.

Bristle Replacement | Replace bristles when the outer diameter is worn to 560 mm (22 inches) and exposed bristles are down to 125 mm (5 inches).

3. Cold Planers

Daily Maintenance | Damage can occur to the conical bit holders and the drum if the attachment continues to run while the bits are not rotating. Before each operation, ensure conical bits are rotating and turning properly. Especially important during asphalt and concrete work, inspect hourly to be sure dust isn’t interfering with rotation. Always use thick gloves or pliers when inspecting the bits as they become very hot during operation.

Weekly Maintenance | Apply lubricant to the planer depth control cylinder ends and the control shafts. Inspect the drum frame and adjustable skid shoes, replacing when needed.

4. Hammers

Daily Maintenance | Lubricate hammers every two hours during normal operation and each hour during heavy use. Use a lubricant that can withstand hot conditions, such as hammer paste. Check the owner’s operation manual for instructions to avoid severe damage. Look for any loose fittings and hydraulic hose leaks before use.

Weekly Maintenance | After 40 to 50 hours of use, inspect the hammer’s pins and bushings for wear or damage. To avoid premature wear, avoid operating for longer than 15 second intervals.

5. Augers

Daily Maintenance | Look for wear or damage on teeth and replace as needed. Ensure bits are in place and bolts are tight. Lubricate and inspect the pivot pin on the drive motor head, looking for any cracks.
