Page 24: Operation
Operation 155E CITY 5. OPERATION 5.1 OPERATING INSTRUCTIONS RECOMMENDED USE The hammer is designed to be used in breaking concrete, road surface or asphalt, hard or frozen ground. It is also suitable for light trenching and benching applications or in ground compacting. It can be also used in breaking small and soft boulders.
Page 25 155E CITY Operation Noise dampening Operating the hammer near residential areas or other noise sensitive areas can cause noise pollution. In order to avoid unnecessary noise, please follow these basic rules: 1. When operating the hammer, keep the tool at a 90 degree angle to the material and the feed force in-line with the tool.
Page 26 Operation 155E CITY CHOOSING TOOLS A selection of standard and special tools to suit each application are available. The correct type of tool must be selected to get the best possible working results and longest life time for the tool. Choosing the best tool type for an application may require some testing, please consult with your local dealer.
Page 27: Daily Operation
155E CITY Operation 5.2 DAILY OPERATION GENERAL GUIDELINES A safety screen is recommended to protect the operator from flying debris. Keep the cabin windows and doors closed during operation. Keep the tool at a 90 degree angle at all times. If the object moves or its surface breaks, correct the angle immediately.
Page 28 Operation 155E CITY 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 hammer and change the position of the tool. Working too long in one spot will create stone dust under the tool.
Page 29 155E CITY Operation When breaking concrete, hard or frozen ground, never strike and pry with the tool at the same time. The tool may break. Bending may be caused by stones inside hard or frozen ground. Be careful and stop striking if you find sudden resistance under the tool.
Page 30 Operation 155E CITY Do not use the hammer to sweep the ground of debris. This may damage the hammer and the housing will wear out more quickly. Do not use the hammer or hammer tools for lifting. Lifting eyes on the hammer are for storage and maintenance purposes only.
Page 31 155E CITY Operation WORKING PROCEDURE Warning! Protect yourself and your neighbourhood against flying chips of rock. Do not operate the hammer or carrier if someone is too close to the hammer. Do not use the hammer, as a standard assembly, under water. If water fills the space where the piston strikes the tool, this generates a strong pressure wave that may damage the hammer.
Page 32 Operation 155E CITY 4. Use the excavator boom to press the hammer firmly against the object. Do not pry the hammer with the boom. Do not press too hard or too gently with the boom. The force is correct when the tracks start to lift slightly from the ground.
Page 33: Mounting And Dismounting The Hammer
155E CITY Operation 6. Start the hammer. 7. Stop the hammer quickly. Do not allow the hammer to fall down and make idle strokes when an object breaks. Frequent idle strokes have a deteriorating effect on the hammer. If the hammer falls through, the housing wears out more quickly.
Page 34: Movement
Operation 155E CITY 5. Remove bucket pins and other parts. 6. The carrier can be moved aside. INSTALLATION 1. Install hammer in the same manner as mounting a bucket. Install bucket pins. 2. Connect hoses. Hammer inlet port is marked on the valve body with "IN" and outlet port with "OUT".
