Maintenance Checklist for Asphalt Pavers
Asphalt pavers are a very large investment for your company. You need them to perform at their best so as not to have unexpected breakdowns, which can cost your work crews valuable time–not to mention you may be charged fines for not completing a job on time. Keeping your asphalt pavers working properly for their full service life takes a great commitment to routine maintenance procedures.
Get Paver Operators Involved
The best way to make sure a paver is in tiptop condition is to get your operators to do the preventative maintenance on his specific machine. The operator uses his paver on a day-to-day basis and will know if something is not operating quite right and needs to be serviced. Your operators are your first line of defense in protecting your investment of a paver. Your operators should do a walk around inspection each day before using the equipment. This is an in-depth inspection and it can take an hour or so to complete and write up the inspection report, but it is well worth it in the long run.
On The Ground Inspection
Your operator’s on the ground inspection includes a walk around inspection of his paver. He should observe the tires, wheels, valve stem caps and lug nuts for inflation, leaks, loose lug nuts and wear of the tires. If the paver has tracks, those should be looked at for cuts or buildup of asphalt or tack. The steering cylinders or ends should be looked at to observe any damages, wears or leaks. The fenders and undercarriage should not have a buildup of asphalt or tack and the fenders shouldn’t be rubbing on the track. The wash down tank needs to be observed for any damages, leaks, signs of wear and make sure it is greased. The push roller and truck hitch should be examined for asphalt buildup, make sure they are greased and the rollers are operational. The augers or auger chain case deflector needs to be examined to make sure it’s clean, undamaged, greased and not overly worn. End gates need to be clean and operational through the full range of motion. Fuel filters and water separators should be looked at for leaks and drain water. DEF fluid should be checked to make sure it is full and isn’t leaking. All steps, screed walkways and handholds should be clean and in good overall condition. Check underneath the machine for any damages or leaks. The screed control needs to be clean, free of damages and function properly. Conveyors and chain guards should also be clean, undamaged, greased properly and have no equipment stored in hoppers. The hoppers and screed lift should be locked in the raised position and all lights are inspected for damages to lens or housing and should properly function.
The Center of the Machine
The center of the paver needs to be inspected in the engine compartment and the center console. Fluid levels should be checked on engine oil, engine coolant, hydraulic oil and pump drive oil. The ATTAC and the radiator or hydraulic oil cooler should be checked for fin blockages and be clean without any leaks. All hoses and belts should be checked for worn areas, cracks and hoses for leaks as well as belts should be tensioned correctly. The operator should check the air filter service indicator and the overall engine compartment should be clean of trash and dirt without any visible leaks. Hopper lift cylinders need to have material build up removed and be greased and the fuel tank and drain valve should be checked for the fuel level as well as for any damages or leaks.
On the Paver Checklist
If you have a canopy on the paver look for any damage or loose mounting bolts. Check the fire extinguisher to make sure it is charged and has no damages to it.
Operator Station Checklist
The operator should climb into the operator station and fully check the seat for its height, weight and make sure he can reach the pedals. Seat belt and seat belt mounting should be adjusted and checked for damage or wear. The platform swivel should lock in position and the backup alarm, lights and horn should be checked to make sure they operate correctly. Mirrors and visual aids should be inspected for damage and adjusted for the best visibility. All gauges, switches, controls and indicators should be undamaged and function properly. The overall cab area should be clean and clear from any trip hazards.
Using this as a daily checklist will help you to keep up with any repairs that you may need in the near future, so you can schedule it on downtime when you aren’t using the paver. This will save you a bundle in the long run over having a breakdown while on the job.
