Job Breakdown SheetsBreakdown No. 2Using A Hammer
1: Examine the hammer.
(see Breakdown No. 1, "Using a Pick"). It is often necessary to place the hand nearest the end of the shaft some little way up the shaft. (see Breakdown No. 1. "Using a Pick" ). Except in roadways it is not possible to get a good swing of the hammer. When breaking stone in a ripping or when using a wedge the hammer may be swung from high above the shoulder. When setting a prop it is usual to grip the shaft close to the head and punch the prop into position, finally driving the prop tight by swinging the hammer in a restricted arc from over the shoulder. These blows should be as direct as possible. When breaking lumps of coal or stone the blows should be directed end on to the cleat. The face of the stone should be cleared of loose material to avoid flying particles when the blow is struck.
