TRENCHER INTENDED USE
This machine is designed for digging trenches in “normal” ground of reasonably soft dirt and stones
up to 3” (15cm) in diameter. Ground that is extremely hard packed, contains larger stones, high clay
content or is in a very dry or frozen condition may be unsuitable for normal trenching. Consider using
a larger trencher, backhoe or other heavy equipment for such conditions.
LUBRICATION REQUIREMENTS
Grease at the intervals indicated per the illustration of grease lubrication points. There is also a grease
diagram decal on the machine.
