Drum spray water must be drained or protected before freezing nights; ice in pumps and lines is a common spring repair.
Clean before greasing
Asphalt grit around the drum housing ends up in fittings. Wipe each zerk before the gun goes on.
Fluids by compartment.
Confirm the fluid type, grade, and specifications in the cold planer maker’s manual before ordering. These examples are not a fitment result for a specific machine.
Hydraulic system
Track drives, conveyor, and steering run hydraulically; match type, grade, and filter interval.
These gearboxes list their own oil, some as an SAE gear grade and some as an ISO industrial gear grade. A1’s catalog does not list ISO 150–460 industrial gear oil.
