Generals and Safety information 

6.1

 

General 

Do not use or install 

the breaker until you can use 

the carrier. Do not rush the learning process. Take 
your time and learn how to operate the breaker 
safely and efficiently.  

 

If there is anything you do not understand, ask 
your Vulcan service center for advice. 

 

The breaker serial number is stamped on a metal 
plate which is located on the back head near the 
inlet connection. 

 

Correct reference to the serial number of the 
breaker is important when ordering spare parts. 
Identifying parts for specific breaker‟s is only 
possible through the serial number

6.2

 

Safety 

1)

 

Manuals 

a.

 

Read this manual before installing, 
operating, or maintaining the breaker. If 
there is anything that you do not understand 
ask your employer or your local Vulcan 
dealer. 

b.

 

Keep this manual in good condition for 
future reference. 

2)

 

Clothing 

a.

 

Proper clothing is important to prevent 
injury. Loose clothing can get caught in the 
machinery and cause bodily harm. 

3)

 

Work site 

a.

 

Inspect the working site before starting work. 

b.

 

Check for potholes, weak ground, hidden 
rocks etc. 

c.

 

Check for utilities like water pipes, power 
lines, and gas lines. 

4)

 

Metal splinters 

a.

 

Injury can be caused by flying splinters 
when driving metal pins in and out. 

b.

 

Always wear safety glasses. 

5)

 

Accumulator 

a.

 

The accumulator is pressurized even when 
there is no hydraulic pressure in the 
breaker. 

b.

 

Attempting to dismantle the accumulator 
without first releasing the pressure can 
cause serious injury. 

c.

 

Do not try to dismantle the pressure 
accumulator, contact your Vulcan service 
center first. 

6)

 

Hydraulic pressure 

a.

 

Hydraulic fluid at system pressure is very 
dangerous. 

b.

 

Before disconnecting or connecting the 
hydraulic hoses, stop the carrier engine and 
operate the controls to release the pressure 
trapped in the hoses. 

c.

 

Keep all personnel away from the hydraulic 
hoses during breaker operation. 

- Regulation – 

 

Observe all of the laws, work site and local 
regulations which affect you and your 
equipment. 

- Practice – 

 

Carrying out unfamiliar actions without practice 
could cause serious injury to the operator and 
any others on site. 

 

Practice away from the job site in a clear area. 

 

Keep other people away. 

 

Do not perform new operations until you are 
confident you can carry them out safely. 

- Equipment condition – 

 

Defective equipment can cause injury to 
yourself and others. Do not operate equipment 
that is defective or has missing parts. 

 

Make sure that the maintenance procedures in 
this manual are completed before operation. 

- Equipment limits – 

 

Operating the equipment beyond it‟ design 
limits can cause damage and be hazardous. 

 

Do not operate the equipment beyond its limits. 

 

Do not try to upgrade the equipment‟s 
performance with non-approved modifications.
