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.

AU106984 G7B 20
OPERATING INSTRUCTIONS
Boom Position When Digging
For the best digging performance and smoothest machine operation, the boom must be in the full down digging position. In this position, the machine is pulled down for better traction. The ground drive simply pulls the digging teeth into the face of the trench.
When the boom is raised from the full down position, the digging load pulls the machine more rearward. This pulling reduces traction and may cause the machine to bounce and pull when the chain contacts roots or rocks.
The rearward pull of the digging operation also works against the ground drive causing the machine engine to work harder.
WARNING: Make sure all people are clear of the machine and working area while the digging chain is rotating. Serious injury or death can result from contact with the digging chain or flying debris.
TRENCHER CHAIN AND TEETH
Chain
The correct chain for the job is very important. Soil conditions determine the type of chain. A chain that is too light will wear fast or break. A chain that is too heavy increases the load and slows the trencher speed.
Digging chains are rated by tensile strength. For example, a 34,000 pound (15,422 kg) chain takes 34,000 pounds of pull to break.
IMPORTANT: Correct chain tension is very important.
See CHAIN TENSION in this manual.
Chain Tension
If you adjust the digging chain too tight or too loose, the digging efficiency of the trencher is decreased and the wear of the parts is increased. See CHAIN TENSION in this manual for correct chain adjustment.
NOTE: When digging in extremely hard ground, remove all deflection from the chain. Remember to adjust the chain for normal digging conditions as soon as possible.
Teeth
The most important parts of the trencher are the teeth.
The type of teeth that you select and the arrangement you use makes a big difference in the digging efficiency and tooth life.
Always keep good sharp teeth at the correct positions on the trencher chain. This will increase the digging efficiency of the trencher chain. Replace immediately any digging teeth that become worn.
When making digging tooth arrangements, follow these instructions.
1. Digging teeth, that are the same width, must be put at equal spaces around the chain. This procedure is necessary to have a balanced digging chain.
2. When digging in wet clay or gumbo, it may be necessary to have less teeth on the trencher chain. A chain with too many teeth can become filled with soil.
This will increase the drag and decrease the efficiency of the digging chain.
3. When digging in hard soil, rock or sandy loam, it can be necessary to install more teeth on the chain. This will increase the efficiency of the trencher chain.
4. Install teeth in the proper sequence and repeat the sequence until the chain is complete for the most effective digging.
5. The conditions shown in the following illustration cause rapid wear of the chain, teeth, and sprockets.
To stop this problem, decrease the ground speed, install more digging teeth, or both. In sand or very loose soil, install dirt drags.

OPERATING INSTRUCTIONS
Cupped Teeth
RT160001
Cupped teeth are the best in cutting light to medium soil.
The cupped design of the tooth cuts the soil and then moves the soil up and out of the trench.
NOTE: Additional digging teeth combinations may be available to meet particular soil conditions. See your Astec dealer for additional information.
BEFORE YOU OPERATE
WARNING: Be careful when working near the side of a trench. Serious injury or death can result if the walls of the trench fall.
WARNING: Make sure all people are clear of the digging chain while the digging chain is rotating.
Serious injury or death can result from contact with the digging chain.
WARNING: Sharp moving parts - do not remove restraint bar. Keep clear of hazardous area. KEEP
CLEAR. Serious injury or death can result from bodily contact.
Starting the Trench
NOTE: Know the location of all underground utilities before starting.
1. Make sure all persons are away from the machine before you start the engine and while you are trenching.
2. To assist in digging a straight trench, stretch a string line along the trench route on the side opposite the auger discharge.
3. Engage the operator presence control.
4. After the engine has reached operating temperature, move the machine so the trencher boom is several feet beyond the starting point of the trench.
5. Align the machine to the center line of the new trench.
6. Lower the trencher boom close to the ground.
7. Move the throttle to the MAX position.
8. Engage the digging chain. Slowly lower the trencher boom into the ground to the necessary depth.
NOTE: The operator presence control levers must be continually engaged or the digging chain will stop.
9. When the trencher boom is completely down to the necessary depth, move the direction/speed control slowly.
10. Use the direction/speed control to adjust the machine speed for the soil conditions.
NOTE: If the drive wheels start to slip excessively, decrease the speed.
11. When the trenching is complete, move the direction/ speed control to NEUTRAL, and slowly raise the trencher boom.
12. Move the digging chain control to the stop position
13. Move the throttle to the MIN position and stop the engine.

Fuel Storage
If you keep fuel in storage for a period of time, you can get foreign material or water in the fuel storage tank.
Many engine problems are caused by water in the fuel.
Fuel Tank Filler Cap
Fill the tank at the end of each day. A full tank will prevent water condensation.

RT130008
1. FILLER CAP
Always stop the engine and let cool before adding fuel.
When adding fuel to the machine, remove the fuel cap
SLOWLY to reduce any air pressure build up.
Add fuel to the bottom of the fuel level limit of the fuel tank. Do not overfill. Wipe up spilled fuel before starting the engine.
Draining the Fuel Tank and Carburetor
Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard starting, and it leaves gum deposits that clog the fuel system. If the gasoline in your engine deteriorates during storage, you may need to have the carburetor and other fuel system components serviced or replaced.
The length of time that gasoline can be left in your fuel tank and carburetor without causing functional problems will vary with such factors as gasoline blend, your storage temperatures, and whether the fuel tank is partially or completely filled. The air in a partially filled fuel tank promotes fuel deterioration. Vary warm storage/ temperatures accelerate fuel deterioration. Fuel deterioration problems may occur within a few months, or even less if the gasoline was not fresh when you filled the fuel tank.
You can avoid fuel deterioration problems by draining the fuel tank and carburetor.
RT130009
1. Place an approved gasoline container below the carburetor, and use a funnel to avoid spilling fuel.
