•  The purchaser must provide proper training to 

ensure the safety of all operators.  Failure to 
provide training may result in serious injury or 
death. 

•  Use only qualified service technicians.  Failure to 

do so could cause severe damage to the 
machine or the operator and will void your 
warranty.

 

•  Operating this piece of equipment without proper 

hearing protection may result in permanent 
hearing loss (dependent on duration of 
exposure).  For best protection from noise, use 
both ear plugs and earmuffs simultaneously.  A 
proper hearing conservation program is the only 
effective means of avoiding hearing damage 
when operating drills with percussive power 
greater than 1 kW.

 

•  Drilling can result in flying particles that 

may cause eye injuries (always wear 
industrial safety glasses).

 

•  ISOLATE all energy sources before servicing 

equipment.

 

•  Apply safe lifting procedures and two-person lifts 

when manually handling the rockdrill.

 

•  Ensure that the drill, accessories, and all actions 

always comply with applicable site and local 
health and safety regulations.

 

•  Never climb on top of the machine.

 

•  Keep clear of rotating drill steel.  Never wear 

any loose clothing that could become entangled 
with the machine.

 

 
 

 
 
•  Be aware that sliding and tilting parts can 

cause pinch and crush points.

 

•  Do not operate this piece of equipment while 

under the influence of drugs, alcohol or 
medication 

•  Always keep your work area clean.  Avoid 

dangerous work environments. 

•  Be aware of the operating zones and 

recommended areas for safe operation.  Keep 
visitors a safe distance away from the work area. 

•  Prepare proper tools and equipment.  Always 

use the correct tool for the job.  Improper or 
homemade tools can cause injury or machine 
damage and will void your warranty. 

•  Use only Boart Longyear replacement parts.  

Failure to do so could cause severe damage to 
the machine or the operator and will void your 
warranty. 

•  Do not change or alter the drill, its components, 

optional equipment, or accessories without prior 
approval from Boart Longyear.  Unauthorized 
alterations will void the warranty, render the 
equipment unsafe, or result in decreased 
performance. 

 
 
 
   

 

  

Ensure you wear all  

  required personal  
  protective equipment

 

UTION

will  be  considered  by  the 

manufacturer if these procedures have not been followed. NO CLAIM AGAINST PRODUCT WARRANTY
