GROUND TRANSPORT OF THE TRENCHER 

 

Raise the digging chain boom. 
 

WARNING

: Contact with the dig chain or auger while in operation will cause serious injury or even 

death. The teeth of the dig chain are sharp. Avoid contact even when the chain is not moving. 

 
Use the Wheel Drive Control to control travel direction. The Wheel Drive Engage Lever must be pulled and held 
to move the trencher. 

 

Pushing the Wheel Drive Control forward causes the machine to move forward. 

 

Pulling the Wheel Drive Control back causes the machine to move backward. 

 

If you are not experienced operating this trencher, a slow ground speed is recommended for your safety. Use 
half throttle for slower transport speed. 

 

Keep away from tires to avoid getting crushed. 

WARNING

: Getting run over by the trencher will cause injury.  

 
 
Never allow anybody to ride on the trencher. 
Never make sudden changes in speed or direction. 
Use extra caution on soft or uneven ground. 
Avoid operating adjacent to drop-offs or embankments. 
Avoid inclines if at all possible. Never use on any incline exceeding the angles shown below. 
 

WARNING

: Navigating on any incline increases the danger of the trencher losing traction or rolling over, 

especially if the surface is wet. If you lose control get out of the way immediately to avoid personal injury.  

Navigation on inclines should be especially slow and turns very gradual. 

 
A 20° maximum incline is allowed.  Honda engines have an Oil Alert system that will automatically stop the 
engine if tipped more than 20°.
