SEE MACHINE’S OPERATOR’S MANUAL FOR

ADDITIONAL INFORMATION.

OUT IN

WARNING

Stop the hydraulic system of the excavator.

2.5 Breaker Operation

The tool contact area must be visible to the

operator to ensure full contact.

Engine Speed

During the breaker inspection, the installer

determines the exact ratio of excavator engine

revs to the appropriate oil ﬂow rate for the breaker.

This information MUST be communicated to the

operator.

Usage Instructions

The breaker can work in all the positions allowed

by the joints of the excavator boom, as long as it is

always pressed perpendicular to the surface of the

material to be demolished.

The operator must maintain the correct pressure to

the breaker. If the pressure is too low, the breaker

retains a part of the energy which will be released

to the excavator boom. The boom will then

undergo dangerous vibration and shaking.

If the pressure is too powerful, the structure of the

breaker can be compromised as well as the metal

plate and the tool.

Excavator Boom Extension

While the breaker is in operation, shorten the

distance between the excavator and breaker as

much as possible. Extend the cylinder piston rods

only partially (Items 1 and 2) [Figure 4].

Figure 4

Avoid Blank Firing

Ensure that the tool does not slip from the surface

[Figure 5]. If the tool is placed incorrectly or is held

weakly to the material, dangerous blank ﬁring can

occur.

Figure 5

2. Operation

WARNING

• The operator MUST follow all manufacturer’s

instructions.

• Do not use without the tool retaining pin.

• Use only tools authorized by the manufacturer.

WARNING

It is absolutely necessary that the operator

respects the ratio of revs to oil ﬂow rate.

Working with a higher or lower number of revs can

cause serious damage to the a hammer.

WARNING

The correct position must be kept during the

whole phase of feed of the tool, operating on the

controls of the bucket and the excavator boom.

Blue Diamond® Attachments10

2.5 Breaker Operation Cont’d

Usage Instructions Cont’d

Operation Near/In Water or Wet Conditions

The breaker cannot operate in water if the water

level exceeds the tool stroke [Figure 6], unless the

breaker is set up for it.

If in doubt, contact Blue Diamond® Product Support.

Figure 6

2.6 Breaker Operations to

Avoid

Blank Firing

Avoid blank ﬁring the breaker. Blank ﬁring causes

early wear and chipping to the tool retainer pin

and the tool itself. Chips from the tool can cause

serious damage. Blank ﬁring can cause the tool to

break prematurely.

Do not Use as a Lever

The tool cannot be used as a lever to move rocks

or other debris. This operation can cause the tool

to break or seize especially if this is done while the

breaker is working [Figure 7].

Figure 7

Removing Large Rocks

Do not remove or pull large rocks

or boulders using the breaker

frame. This can cause some parts

to become unwelded and the plate

can warp [Figure 8].

Figure 8

Stagnant Movement

Do not hammer in the same

location without moving for

more than 30 seconds. In the

event of a very hard surface,

it will be necessary to change

position very often until softer

ground is found [Figure 9].

Preheat Oil

Never forget to preheat the oil before beginning

operation, especially when there are low outdoor

temperatures. It is a good practice to operate the

translation control and those of the excavator

boom’s central piston to the end of the stroke

until the oil reaches a temperature of 77–86°F

(20–30°C).

2. Operation

YES

WARNING

If you stay in the same location too long, the drill

can swell up, the tool can seize, and the oil can

overheat.
