Hammer (option) 63
Attachment and removal of hammer with quick
fastening
Attaching the hammer
1 Place the machine on firm and level ground. Position the mach-
ine as required for the hammer laying flat on the ground.
2 Slowly lower the boom, until the tapered journals of the attach-
ment carrier are in line with the fitting grooved on the hammer.
3 Once the tapered pins are located in the fitting groove the at-
tachment carrier automatically locks the hammer.
4 Clean the hydraulic connections on hammer and boom.
IMPORTANT! Protect the hydraulic connections against dirt,
because only this will ensure the correct function of hydrau-
lic connections and hydraulic system!
5 Connect the hydraulic hoses of the hammer to the hydraulic
connections (return line (A) and pressure line (B)) on the boom
by sliding the hydraulic coupling (C) accordingly. Then lock the
hydraulic coupling (C) with the black safety rings (D).
IMPORTANT! Ensure correct engagement of the hydraulic
connections.
NOTE! Depending on the equipment the hydraulic connec-
tions on the boom can vary from the illustration and the des-
cription.
WARNING!
In order to rule out any risk of an accident caused by
unhooking of the hammer, move the hammer (slightly
above the ground) to check whether the locking is correctly
positioned. Excessive clearance indicates that the locking
system in position (4a) has failed and the unit is held in
safety position (4b). In this case the process must be repea-
ted, until the hammer is properly locked in position (4a).
WARNING!
Before removing or connecting hydraulic hoses the engine
must be shut down and the control levers shifted to all
directions, in order to relieve any trapped pressure. It must
be strictly assured that the engine cannot be started after
hydraulic couplings have been opened.
