USING THE HYDRAULIC IMPACT BREAKER
THIS HYDRAULIC DEMOLITION HAMMER, AS A GENERAL RULE, SHOULD BE USED WITH THE SAME TECHNIQUE AS A
JACKHAMMER. CHOOSE THE APPROPRIATE TOOL IN ORDER TO OBTAIN MAXIMUM PRODUCTIVITY. THE PROFILE
OF THE TOOL SHOULD BE CHOSEN ACCORDING TO THE NATURE OF THE MATERIAL, DEPENDING ON THE TYPE OF
JOB: QUARRY, EARTH MOVING, TRENCH WORK, TUNNELS,
DEMOLITION, ETC.
a) Position the carrier so that the reach to the work is adequate. Ensure that the carrier
is in a stable position and is not placed on a crumbling or slipping surface during
operation. This guarantees a constant load on the hammer.
b) Place the hammer tool perpendicular to the surface to be broken. Always act with the
carrier arm, keeping the hammer perpendicular to the work and describing a slight
arc, closing the arm towards the operator. This method of operation will dramatically
extend the life of the tool and bushing.
