CHAPTER 5 

– 

Maintenance and Selection of Consumables

 

 
 

5.1 

Role of the Operator 

 
The  person  operating  and  maintaining  the 

Brobo  Group  3M  Drill

  must  familiarise  themselves  with  these 

instructions  for  their  own  safety  and  that  of  others,  in  addition  to  safeguarding  the  production  of  the  machine.  
Responsibility must be taken by the user on the general maintenance and up keeping of the unit as specified in 
this chapter, with particular emphasis on:   
 

 

Check to ensure that other operators of the machine always aware of and comply with the relevant safety 
instructions and standards as specified in 

Chapter 2

 

- Safety and Accident Prevention

.  Therefore, check 

that  the  safety  devices  are  operational  and  work  perfectly  and  that  personal  safety  requirements  are 
complied with. 

 

 

Ensure that the working cycle is efficient and guarantees maximum productivity, inspect the: 

-

  Functions of the main components of the machine 

-

  Sharpness of the drill bits and lubricating fluid 

-

  Correct working parameters for the type of material being drilled 

 

 

Verify that the quality of each drilled hole meets the requirements and that the final product is free from 
any machining defects. 

 

5.2      Maintenance Requirements 

 

 

All  maintenance  must  be  carried  out  with  the  power  switched  off  and  the  machine  in  emergency  stop 
condition. 

 

 

To guarantee perfection operation, all spare parts must be 

Brobo Group

 originals. 

 

 

On  completion  of  maintenance  works,  ensure  that  the  replaced  parts  or  any  tools  used  have  been 
removed from the machines before starting it up. 

 

 

Any behaviour not in accordance with the instructions for using the machine specified in this manual may 
create hazards and/or safety risks for the operator. 

 

 

Therefore, read and follow all the instructions for use and maintenance of the machine and those on the 
product itself. 

 

5.3 

General Maintenance of Functioning Components 

 

            
The general maintenance operations that should be carried out regularly are as follows: 
 

i) 

Keep the rack lift table, overall machine and path of the drilling free of any offcuts, accumulated swarf and 
lubricants by using compressed air or preferably thread-free cloth. 

 

ii) 

Lubricate the drill shaft and rotary chuck regularly

 

with an 

NLGI 2 extreme pressure grease

Shell Alvania 

No.1 grease

 or equivalent. 

 

iii) 

Check the belt condition and tension regularly.

  

Do not over tighten belts,

 as this will inadvertently exert 

tension  on  the  spindle  and  motor  bearings.  To  provide  the  right  tension,  follow  the  belt  manufacturer’s 
recommendations and specifications.
