Concrete dust is the usual cause of early engine wear. Service air filters as often as the maker says, and more often on dry cuts.
Wet cutting and bearings
Water-fed cutting keeps dust down but sends slurry toward bearings; grease after washdown to push water out.
Fluids by compartment.
Confirm the fluid type, grade, and specifications in the concrete saw maker’s manual before ordering. These examples are not a fitment result for a specific machine.
Handheld cut-off saw
2-stroke saws use the oil and mix ratio the saw maker lists.
