MOUNTING AND DISMOUNTING OF EQUIPMENT

When you mount and dismount equipment on the machine ensure that the hydraulic
hoses and the ropes do not get tangled with machine parts. Pay attention also to the pile
arms, they should be wide open in order not to touch the hammer and other pieces of
equipment. Close the pile arms only when you position the pile. You can mount the
equipment on the machine in different sequences. The steps are described in the
respective sections below. In normal operation you may need to replace the drive cap
cushion or to dismount the ram block which are detailed in hammer-manual.

MOUNTING OF THE HAMMER

equipment to the vertical position. Move the machine as necessary. Adjust the
inclination and position of the leader so that guide claws are in the right position. Lock
guide claws to the leader.
Attach the hammer rope to the lifting eye of the equipment. Remove the rope and chains
which you used to lift the equipment. Connect the hydraulic hoses to the hammer. If
necessary, put the hammer to the transport lock and lower the leader with the hammer.
Also connect the electric cable to the hammer. Open the valves of the hammer hydraulic
hoses, which are located on the front side of the machinery deck. Dismount the hammer
in the opposite sequence.
Before dismounting the hammer:
- lift the hammer to the top of the leader
- stop the engine
- open the tank pressure relieve valve, located in the hydraulic compartment
- wait 5 to 10 minutes
- close the tank pressure relieve valve and valves of the hammer hydraulic hoses on
the front of the machine
- start the engine
- lower the hammer down

Daily operation section
Use the two lifting points on the top side of the
hammer to lift it. Lay the equipment on the
ground in front of the machine as shown in the
picture. Place wooden supports underneath the
equipment. Any sand or dirt which goes into the
guides will be detrimental to the life of the wear
pads.
Plug the hydraulic hoses with plastic caps at
both ends temporarily during mounting and
transport of the equipment. Be careful that no
dirt enters the hoses, as that will eventually be
detrimental for all the hydraulics.
Lower the leader foot down and incline the
leader forward so that the cathead is above the
lifting points. Attach the rope of the pile winch
with two slings to the lifting points. Lift the
