Couplings and grease hoses
4.5.1 Installation of the couplings
1. Determine the position for the quick coupler on the dipper arm of the machine before
disconnecting the hydraulic hammer and mount or weld on a support bracket in this
position.
2. Mount preferably the male part of the quick coupler rigidly on the dipper arm and
mount the female part on the hose of the hydraulic hammer.
3. Do not forget to mount the dust cap and dust cover supplied so that the quick couplers
can be sealed against soiling after disconnection of the hydraulic hammer.
4. Now determine the screw thread at the greasing point on the hydraulic hammer and
mount the correct coupling. Pay attention also to the most favourable layout of the hose
to the hammer.
ATTENTION
Experience has shown that the vibrations of the hydraulic hammer, a
coupler can quickly come loose of even break off completely. We there-
fore recommend that only steel couplings are used, preferably with R1/4”
screw thread and that these are mounted with Loctite rather than Teflon
tape.
It is also important that the hose in the opposite direction is laid away
from the bit of the hammer. This ensures the least chance of vibration
damage to the hose and coupling (see illustration below).
