OPERATING INSTRUCTIONS
AU106984 G7B 20
Engine Speed
Before starting the engine make sure the area around the
machine is clear.
Do not run the engine at low idle speed for long periods
of time. This can cause a low operating temperature.
Long periods at idle speed can cause acids and deposits
to form in the engine oil.
It is recommended that you run the engine at full throttle
when operating conditions permit and when safe.
Before You Operate Each Day
Check all controls in a clear area.
Driving the Machine
1. Start the engine.
2. Ensure the direction/speed control lever is in the
NEUTRAL position and the digging chain control lever
is in the STOPPED position.
3. Engage the operator presence control lever.
4. Raise the trencher boom by pulling back on the boom
control lever.
5. Slowly move the direction/speed control to move
forward or to move rearward.
Stopping the Machine
This machine has hydrostatic braking. When you move
the direction/speed control lever to the NEUTRAL
position, the machine will stop.
TRENCHER OPERATION
Selecting Correct Tools for the Job
You can increase the digging speed and still get long life
from your trencher if you use the correct trencher
components. Read the following section on how to select
the correct combination of parts for your machine.
Then, see your Astec dealer and ask for complete
information on trencher parts.
As a general rule, always select the shortest boom,
lightest chain and lightest teeth to get the job done.
When you make the selection, know the trench width,
trench depth, soil and weather conditions of the job.
1. Select the boom length.
2. Choose the tooth width.
TRENCHER BOOM
The trencher boom is designed to give support to the
chain when digging. The boom design also prevents rocks
from getting between the chain and the boom and gives
full support to the digging chain.
Booms are available in sizes from 2 to 4 feet digging
depths (.6 to 1.2 meters).
