Working with the hammer
Precautions
IMPORTANT! If the hammer is connected to an attachment
carrier the attachment carrier must be regularly inspected for
damage!
Q
The windscreen must be kept closed and locked during ham-
mer operation. Make sure that no persons are in the working
range of the machine, rock chips may fly around.
Q
Keep other persons out of the danger zone when using the
hammer. During hammer operation the danger zone is the area
around the machine and at least 15 m beyond the reach of the
machine.
Q
Do not operate the hydraulic cylinders closer than 50 mm (2 in)
from their end positions.
Q
Park the machine on a level surface and lower the dozer blade
to the ground.
Q
Listen the hammering noise. The hammer blows must have a
regular rhythm. Without delays or interruptions.
Q
Avoid loads on the hammer in diagonal or vertical direction, sin-
ce this can increase the wear on the hammer’s bushings.
Q
Do not swing the hammer against rocks, concrete etc.
Q
Keep the tool under a right angle to the surface of the object.
Apply the feed force in line with the tool. Avoid minor uneven-
ness of the objects which could easily break off and cause idle
blows or incorrect working angles. If vertical structures (e.g.
brick walls) are to be demolished, the tool must be maintained
in a vertical position to the wall.

Do not use the hammer or hammer tools for lifting loads. Lifting
eyes on the hammer are for storage and maintenance purpo-
ses only.

could give way.
