Storage
WARNING Hydraulic breaker / working tool
fall
The hydraulic breaker and the working tool are
heavy. If they topple over or fall down from where
they are stored, injury may be the result.
► Store the hydraulic breaker and the tool so that
they cannot topple over or fall down.
The hydraulic breaker must be stored in an upright
position to avoid its seals being damaged.
If the hydraulic breaker is not used for a long time,
the following points have to be considered to protect
the hydraulic breaker from corrosion:
♦
Remove the hydraulic breaker from the carrier
(see chapter Removing the hydraulic attachment
from the carrier).
♦
Clean the hydraulic breaker carefully (see chapter
Cleaning).
♦
Dismount the working tool (see chapter Working
tool/Removal).
♦
Lubricate the front part of the piston, wear bushing,
and the retainer bars.
♦
Store the hydraulic breaker in a dry place.
Always keep the breaker in an upright position, if
stored for a long time and so that it cannot topple
over.
