Set Up
Prepare Spoils Removal
The MT12 MicroTrencher is designed to operate optimally with an 800 cfm vacuum excavator unit to
remove spoils. If vacuum excavator is not available, set up unit to operate without it.
With Vacuum Excavator
1. Connect vacuum hose on excavator to vacuum hose on tractor.
2. Operate vacuum unit at full speed for best results. Full vacuum flow to the microtrencher is necessary
for best spoils removal.
Without Vacuum Excavator
1. Cap vacuum hose on tractor.
2. Remove chute plates (1).
3. Install spoils chutes (2).
Read operator’s manual. Follow safety rules and know
how to use all controls. Your safety is at stake.

To help avoid injury: Do not operate without blade cover and chutes or chute plates installed.
IMPORTANT: Ensure that vacuum hoses are clear, vacuum filters are clean, and separator
canister is empty prior to operation.

chute as indicated by decal on chute.
