5.6. Dismounting the hydraulic hammer from the carrier
WARNING!
Wear safety shoes to protect feet.
Personal injury can result from dropping pins during dismounting.
Put the hydraulic hammer on a clean, flat, level surface, and engage the parking brake on the carrier
machine.
1. Close the stop valves completely.
2. Disconnect the hydraulic hoses (I, O) from the stop valves.
3. Ensure no leakage occurs from hoses and stop valves.
4. To prevent contamination, apply the end caps to the stop valves and hose plugs to the hoses.
5. Remove the stop rings from the arm and link pins.
6. Lift the arm away from the hydraulic hammer, so that the hydraulic hammer can be carried away, or
another attachment mounted on the carrier.
5.7. Fitting / removing the chisel
WARNING!
The chisel shall only be installed in the way described. Failure to do so could allow the chisel
to be drawn out from the hammer with force possibly causing safety accidents.
When installing the chisel, the carrier must be switched off before fitting or removing the
chisel. Always wear safety glasses and gloves because metal chips or debris may fly off when
driving the chisel or the chisel pins.
Never put fingers in the chisel pin-bores of the hammer.
Do not stand in front of chisel; possible blank blow caused by the pressure trapped inside the
hammer can cause personnel injury.
In case of large size hammer, the chisels are very heavy and difficult to lift by hands. Always
use a hoist with a sling when lifting the chisel. Be careful of falling down.
After operating the hammer, the chisel, especially the tip, may remain very hot for some time
and can cause severe burn.
IMPORTANT!
Use only genuine PRODEM chisels. Use of other brands of chisel may occur serious trouble
to the hammer and cause warranty rejected.
It is important that the chisel be used correctly for longer chisel life. Pay particular attention to
Section “
6.2. Correct working methods
”, and refer to a extra document “A guide for profer
use of tool” to determine the warranty guide for chisel failure.
In general the chisel is not fitted when the hammer is delivered. Before fitting the chisel, move the hydraulic
hammer into a horizontal position using the carrier and place it on a suitable support (e.g. squared beams).
