Power trowels should have blade arm bushings, gearbox oil levels, and blade wear checked on a regular schedule, typically after every significant floor programme or at set operating hour intervals for machines in continuous use. Hydraulic pitch control lines and safety interlocks on ride-on units also need periodic inspection. Skipping these checks is a common cause of uneven finish quality on subsequent floors. Sparkline Group offers servicing support for trowels supplied on rental or purchase agreements. Regular maintenance keeps finish quality consistent across a multi-floor programme.
