TRENCHER DELIVERY AND ASSEMBLY INSTRUCTIONS
Upon delivery, check for freight damage and any missing items. Report any damage immediately to the
carrier and Barreto Manufacturing and take pictures if possible. Remove trencher from shipping crate.
When documentation refers to “right side” or “left side”, it is relative to the operator’s position with both
hands on the handlebars.
Install cushion pad, boom cushion, and boom.
CAUTION!!
The boom is heavy. You may want help to lift it
into place. Push boom on as far as it will go onto the boom mount (part of the chain motor housing
weldment). Be sure adjuster screw is backed out.
