Check all components for wear, deformation, corrosion and secure mounting.
Check oil, fuel, grease and water levels, top up as necessary. The machine must be
standing on level ground at this time.
Check components that come in contact with concrete, replace worn parts.
Check the wear condition of the conveying pipework by knocking it or by using a wall
thickness gauge (see section 9.8) and replace worn parts. The minimum wall thicknesses
can be found in the diagram in section 9.8.2.
Check all filter clogging indicators.
Check lubrication system for operation.
Lubricate the conveying piston with grease (unless the automatic piston lubrication option is
fitted).
Visually check all hydraulic lines and screwed joints for leak-tightness.
