Dismantling

Dismantle percussion unit

♦

Remove hydraulic breaker from the carrier

according to the Safety and operating instructions

of the hydraulic breaker.

♦

Remove working tool according to the Safety and

operating instructions of the hydraulic breaker.

WARNING Hoist tipping over /

hydraulic attachment falling

The hydraulic attachment is heavy. The hoist/lifting

equipment and/or hydraulic attachment tipping

over or falling may cause serious injury and material

damage.

► Only transport the hydraulic attachment with

lifting equipment with the right load-bearing

capacity for the weight of the hydraulic

attachment.

► Only lift and secure the hydraulic attachment with

lifting gear (ropes, chains, links etc.) with the right

load-bearing capacity for the weight to be lifted.

► Make sure that there is nobody near or under the

suspended hydraulic attachment.

► Secure the hydraulic attachment to the loading

area with ropes or chains; use any available

transport lugs.

♦

Stand breaker box with percussion unit vertically

and secure against falling over.

♦

Remove Allen screws (D) using Allen key size 22

and the pairs of lock washers (C) and remove

adapter from breaker box using a hoist/crane.

♦

Remove elastic pad (A).

♦

Remove cap (B).

If CP-Lube is installed:

♦

Remove cover.

♦

Dismantle grease line and oil line between

CP-Lube and percussion unit.

♦

Remove Allen screws and the pairs of lock washers

using Allen key size 10.

♦

Remove CP-Lube unit.

RX 22Optional equipment

♦

Screw two load rings (E) M 16x24 (Part-Id.-No.

3363 1032 49) into the two threaded bores on

the upper face of the cylinder cover as far as they

will go.

♦

Using a hoist/crane, lift the percussion unit of the

hydraulic breaker out of the breaker box.

WARNING Abruptly loosen parts cause

injuries

Using the hoist as a pulling device if the percussion

unit has jammed in the breaker box can cause serious

injuries.

► You must not use the hoist as a pulling device.

♦

Secure breaker box against falling over.

♦

Stand percussion unit vertically and secure against

falling over.

♦

Remove plastic parts and plugs from the breaker

box.

♦

Lay the breaker box horizontal on a suitable base.

Welding

WARNING Harmful vapors

Chisel paste is flammable. Harmful vapors are

generated when chisel paste is burnt.

► Remove all chisel paste and other contamination

from the breaker box.

► Provide sufficient ventilation during welding.

► Wear personal protective equipment (ambient

air-independent breathing mask) if no air

extraction system is available.

WARNING Risk of fire / explosion

Flammable detergents and chisel paste residues can

ignite or cause an explosion during welding.

► Do not use flammable detergents.

► Carefully remove all detergent residues from the

breaker box.

NOTICE Damage to the breaker box

As the worn parts burn away, the breaker box may

buckle as high levels of heat are produced and the

steel’s properties may change.

► Once a wear part has burnt away, leave the

breaker box to cool before removing the next part.

♦

Remove worn parts one at a time using a flame

cutter or the weld seams removed using a cutting

wheel.

♦

Grind flame-cut areas on the breaker box flat.

Weld seam preparation

♦

Before starting welding work, remove all

contamination on and around the seam edges.

Scale, rust, oil, paint and moisture give off

hydrogen which can jeopardise welding results

and result in cracks.

Preheating temperature

To avoid cracking, a higher working temperature is

recommended depending on steel plate grade,

overall plate thickness and hydrogen content.

♦

Preheat new wear parts to 150 °C to 200 °C.

Optional welding processes

> arc-welding DIN EN ISO 4063

> gas-shielded welding DIN EN ISO 14610

Post-treatment of welds

♦

Make welds without notches or grind free of

notches in order to reduce tension.

♦

Run a non-destructive surface crack test (but at

least a visual weld seam check) of all weld seams.

Tack welds and root beads are the points which are

most susceptible to the formation of cold cracks.

♦

If you find cold cracks in a welded joint, you have

to grind them out or gouge them out with a

carbon arc (grind joint edges) and then perform

a repair weld.

Assembly

Fit percussion unit in

breaker box

WARNING Hot breaker box

The breaker box becomes very hot during welding.

Touching them may lead to burns.

► Never touch the hot breaker box.

► If you have to carry out activities where you have

to touch the breaker box, wait for it to cool down

first.

♦

Stand the breaker box upright.

NOTICE Damage to the plastic parts

The breaker box becomes very hot during welding.

The plastic parts may deform and glue, if you fit

them into the hot breaker box.

► Leave the breaker box to cool before fitting the

plastic parts.

WARNING Hands and fingers being cut

off or injured

Bores and surfaces can act like a pair of scissors and

cut off or injure parts of your body.

► Never use your hands to locate or check the

position of the plastic parts fitting the percussion

unit in the breaker box.

♦

Fit plastic parts and fix in position using

double-sided adhesive tape.

♦

Lift up percussion unit using a crane/hoist and

lower into breaker box.

key size 10.

♦

Secure Allen screws with Loctite 243.

♦

Fit grease line and oil line between CP-Lube and

percussion unit.

♦

Route grease line and oil line as shown on the
