BEFORE USING THE HYDRAULIC BREAKER (optional

● Do not attempt to operate the hydraulic breaker unless you have first read and completely understand the safety messages and instructions in this manual and those of the hydraulic breaker manufacturer. ● Operating the hydraulic breaker requires full attention and care on the part of the operator to avoid accidents. Know the hydraulic breaker’s capabilities, limitations and the working area required. ● Every day, inspect the hydraulic breaker to detect any signs of oil or hydraulic fluid leakage. Tighten the connections or replace any defective components and grease as necessary. ● Make sure the hydraulic breaker is in good condition. Never use a hydraulic breaker which is in poor condition or if there are components missing, as this could cause serious injury. ● Make sure the maintenance procedures explained in this manual are carried out correctly.

USING THE HYDRAULIC BREAKER (optional)

● Protect yourself and the vicinity from flying chips of rock. ● Wear ear protection when working with the machine door or windows open. ● Move everybody away before operating the hydraulic breaker. ● Never immerse the hydraulic breaker in water as this could cause damage. ● Never use the hydraulic breaker to sweep the ground to spread rubble, to push objects or carry out lifting operations. ● Do not operate the hydraulic breaker with the attachment cylinders at the end of their stroke (extended or retracted). ● Do not operate the hydraulic breaker if the tool is in contact with some part of the machine. ● Place the tool against the object at a 90 degree angle. Avoid small irregularities on the object which will break easily and cause either idle strokes or an incorrect working angle. ● Use a safety screen to protect yourself from flying debris. Keep the cab windows closed during operation.

● Listen to the noise the hydraulic breaker makes while you are using it. If the pitch of the noise rises and, at the same time, the force of impact diminishes, this means that the tool is not properly aligned with the material and/or that there is not enough downward force on the tool.

Realign the tool and press it firmly against the material. ● Do not strike in one spot for more than 15 seconds at a time. If the object does not break, or if the tool does not penetrate, stop the breaker and change the position of the tool. ● For the hydraulic breaker to be most effective when breaking boulders work progressively in small steps from the outer edge towards the middle. ● When breaking hard or frozen ground, use the benching method.

Start by clearing a small area working from the edge. Then continue by breaking material towards the open area. ● Do not operate the hydraulic breaker in the air, with nothing to hit.

Frequent idle strokes have a deteriorating effect on the hydraulic breaker. ● When breaking concrete, hard or frozen ground, never strike and pry with the tool at the same time. The tool may snap off. Bending may be caused by stones inside hard or frozen ground. Be careful and stop striking if you encounter sudden resistance under the tool. ● Keep the tool at a 90 degree angle at all times. If the object moves or if its surface breaks, correct the angle immediately. Keep the hydraulic force and tool aligned. ● The tool shank should be kept well greased during operation. Regular visual checks should be made during operation.
