STK OPERATOR’S MANUAL                     9/4/18                                     Page 4 of 14 

SAFETY INSTRUCTIONS OVERVIEW CONTINUED 

 

We recommend having a fire extinguisher capable of extinguishing class A, B & C fires in the 
operating area.  

 

 

WARNING: 

Do not operate the STK near any source of flammable dust or vapor. Sparks from 

the engine can cause a fire or explosion in a flammable atmosphere.  

 

WARNING

: Shut off engine and allow it to cool before refueling. Sparks and heat from the 

engine may ignite fuel. 

 

Work site preparation:  

DO NOT dig until all utility lines have been identified and authorized to dig. Identify and remove or 
avoid all safety hazards. Ensure worksite is well lit. Keep others away from the STK while operating. 
Select job sites free from bystanders. If the job site is near a road or a pedestrian pathway and cannot 
be moved, warn and divert both motorized and pedestrian traffic. As appropriate and legal, use traffic 
flag personnel, signs, cones and lighting devices to ensure safety. Diverting traffic and working in 
congested public areas may require permits or other such legal considerations. It is your 
responsibility to know and follow all applicable laws. 

 

Contact with underground utilities:

 

WARNING:

 If you hit any underground utility line or pipe immediately evacuate the area and 

call 911 (emergency services). There are numerous types of dangerous underground utilities.  

 

IF AT ANY POINT AND FOR ANY REASON YOU DO NOT FEEL CONFIDENT ABOUT 
OPERATING THE STK OR RECOGNIZE THAT YOU CANNOT SAFELY OPERATE THE STK, 
STOP IMMEDIATELY.  RELEASE THE TRENCH DIG CHAIN CONTROL LEVER, TURN OFF
