hammer or hoses.
Check that the hammer moves normally inside the housing and that vibration
dampening elements (pads and buffers) are in good condition.
Check the condition of wear plates by moving hammer with a pry bar from side
to side inside housing. The maximum allowed clearance is approximately ±10
mm.

100 operating hours. Contact your local dealer for more information about the initial
50-hour inspection.
