or a machine with a rebuilt engine, the following
procedure should be followed:
6. Test the radiator cap before hot weather starts.
Replace the cap if damaged.
1. Keep the engine at normal operating temperatures.
7. Keep the coolant at the correct level in the coolant
reservoir and in the radiator and make sure the
correct solution of 50% Ethylene Glycol and 50%
water is used in the cooling system.
2. Do not run the engine at low idle speeds for long
periods of time.
3. Operate the machine with normal loads for the first
eight (8) hours.
4. See Run-In Maintenance Schedule in this manual for
additional information.
OPERATING IN COLD WEATHER
Cold weather conditions cause special problems. During
these conditions your machine will require special
attention to prevent serious damage. Cold weather
maintenance will extend the service life of your machine.
RUN-IN MAINTENANCE SCHEDULE
The following items are to be done during the Run-In
Period and are in addition to the items listed above as well
as those listed in the Lubrication/Maintenance Chart.
1. BATTERY AND ELECTRICAL SYSTEM: Clean the
battery and make sure the battery is at full charge.
BEFORE OPERATING A NEW MACHINE
NOTE: A fully charged battery at -17°C (0°F) has
only 40 percent of the normal starting power. When
the temperature decreases to -29°C (-20°F), the
battery has only 18 percent of the power remaining.
Check the operation of the parking brake. See Parking
Brake Check in this manual.
AFTER FIRST 10 AND AFTER 30 HOURS OF OPERATION
Check the torque of the bolts/nuts retaining the trencher
chain drive sprocket ......160 to 190 Nm (120 to 140 lb ft)
Machine is shipped with a maintenance free battery. If a
different battery is used and you add water to the battery
when the temperature is below 0°C (32°F), make sure
you charge the battery or run the engine for
approximately 2 hours. This procedure will prevent

side or allows the plow blade to move around the
obstacle. Be sure the swing control is in the FLOAT
position. Know the location of underground lines
before starting.
3. For sharp turns without a service hole, if the area is
open, you can lay cable in a 90 degree turn with a
radius of about 0.9 m (3 feet).
EXAMPLE: When making a right turn, put the plow
swing control in FLOAT, then, turn the front wheels to
the right.
NOTE: The links connecting the chute to the blade are
replaceable. Check for wear and freedom of movement at
frequent intervals. Replace the links before they wear out
and the chute breaks away from the blade.
Raising the Blade
If the cable or tubing is not to be plowed into a hole or
trench at the end of the run, proceed as follows:
1. Slow the machine speed and plow vibration.
Service Connections
1. When making a service connection, dig a hole to the
depth the cable is being laid and no wider than 0.6 m
(2 foot). The machine can then drive over the hole
with no problem.
2. Have sufficient cable slack above the chute as the
plow is raised. Damage can result to the cable at the
chute outlet if cable slack is insufficient. Lubrication of
the cable is also recommended in this operation.
2. To make the connection, plow directly into the hole.
Stop the vibrator before the blade enters the hole.
Make a loop in the cable and secure. Move the
machine forward while pushing the cable down the
chute. Start the vibrator slowly after the blade enters
the ground.
3. Move ahead slowly as the plow is slowly raised. When
about halfway out of the ground, stop the vibration
and continue raising the blade. Make sure the swing
control is in the HOLD position before the blade is out
of the ground.
NOTE: The life of the cable plow will be reduced if the
vibrator is operated when the blade is out of the ground.
Operating Tips
•
For normal operation, the boom swing control lever
must be placed in the FLOAT position.
•
The plow motor speed can be adjusted to any speed
in the operating range to obtain the best
performance.
RB97D084
By changing the ground speed setting and the plow
shaker speed setting at the same time, it is possible
to optimize the plow speed for the given soil
conditions. Start with plow shaker speed control
about midway and adjust ground drive speed for best
performance (3 to 10% wheel slip). Adjust the shaker
speed up or down and note performance increase/
decrease. Continue until best performance is
obtained.
Turning
The machine can make sharp or gradual turns depending
on the conditions of the ground.
1. If a sharp turn is to be made with little room to turn
the machine, dig a hole the same depth as the cable.
It must be no wider than 0.6 m (2 feet). The machine
can then drive over the hole, laying cable into it. Stop
the blade vibration, and move the swing control to
HOLD before the blade enters the hole.
2. As soon as the cable chute is into the hole, remove
the gate and cable. Raise the blade from the hole.
Without cutting the cable, move the machine around
to the side as the cable continues to move and lower
the blade into the ground. Install the cable into the
chute, install the gate, and plow away from the hole.
The blade must be started into the ground before
starting the vibration.

•
In general, loose or sandy soils can be plowed with a
slow plow shaker speed.
•
Tougher clay soils require plowing with faster plow
motor speed.
•
An operator will usually find that the fastest plowing
speed will be achieved when the ground drive speed
and plow shaker speed are set to provide the least
amount of vibration at the operator’s area.

Service Connections
IMPORTANT: Never reverse the machine with the plow
blade in the ground. Damage to chute and cable will
result.
1. When making a service connection, dig a hole to the
depth the cable is being laid and no wider than 0.6 m
(2 foot). The machine can then drive over the hole
with no problem.
NOTE: Slow the machine speed if the tires slip during
plow operation.
2. To make the connection, plow directly into the hole.
Stop the vibrator before the blade enters the hole.
Make a loop in the cable and secure. Move the
machine forward while pushing the cable down the
chute. Start the vibrator slowly after the blade enters
the ground.
NOTE: Slow the machine speed if the blade raises out of
the ground during plow operation.
IMPORTANT: Slowly lift the plow blade out of the
ground as the machine moves forward. This will prevent
cable damage.
NOTE: A second method of starting is shown. A hole is
dug next to the building and the blade is lowered to full
depth. The cable or tubing is threaded into the chute and
pushed through the wall. Secure the cable end and slowly
move the machine forward. As the blade enters the
ground, start the vibrator.

Without cutting the cable, move the machine around
to the side as the cable continues to move and lower
the blade into the ground. Install the cable into the
chute, install the gate, and plow away from the hole.
The blade must be started into the ground before
starting the vibration.
RB97D083
9. Increase the creep speed until the tires begin to slip
or lose traction. Do not allow tires to slip too much,
this will lower the efficiency of the machine.
10. If an underground obstacle is encountered, increase
vibrator speed and maintain slight forward pressure
with the machine. This lets the obstacle move to one
side or allows the plow blade to move around the
obstacle. Be sure the swing control is in the FLOAT
position. Know the location of underground lines
before starting.
3. For sharp turns without a service hole, if the area is
open, you can lay cable in a 90 degree turn with a
radius of about 0.9 m (3 feet).
EXAMPLE: When making a right turn, put the plow
swing control in FLOAT, then steer the blade to the
right and allow the blade enough distance to move
completely to the right. Then, turn the front wheels to
the right and crab steer the rear wheels to the right.
Control the turn with the blade steering control.
NOTE: The links connecting the chute to the blade are
replaceable. Check for wear and freedom of movement at
frequent intervals. Replace the links before they wear out
and the chute breaks away from the blade.

Raising the blade
•
In tough soils, a blade with an increased forward
angle or a toe at the bottom of the blade will provide
best performance. In loose, sandy soils or in other
conditions where plow floatation over the top of the
soil is a problem, it is recommended to use a blade
with less angle (closer to vertical) without a toe.
•
Highest plowing productivity is achieved when the
plow is centered behind the machine. As the plow is
offset from the centered position, the draft of the
blade will cause the tires to slip more easily.
•
When the plow is offset from center, it can be helpful
to turn the rear wheels slightly toward the side the
plow is on. This will cancel out the sidedraft of the
plow and let the front wheels be used for normal
steering.
•
The plow can be offset using the boom steering
control, or if the plow is in the ground, the boom
swing control lever can be pushed down and put into
float position. Then, the plow can be offset by
steering the blade.
•
Always turn the shaker motor off whenever the plow
is out of the ground or when the plow is in the ground
with the machine stopped. This will prevent excessive
vibration.
•
The plow swing will assist in making tight turns while
plowing by reducing side draft. Return the swing
control to FLOAT when making minor direction

If the cable or tubing is not to be plowed into a hole or

3. Move ahead slowly as the plow is slowly raised. When
about halfway out of the ground, stop the vibration
and continue raising the blade. Make sure the swing
control is in the HOLD position before the blade is out
of the ground.
NOTE: The life of the cable plow will be reduced if the
vibrator is operated when the blade is out of the ground.
Operating Tips
•
•
The plow must be operated with the lift control in the
FLOAT position or excessive vibration will be
transmitted to the prime mover which can result in
damage to the machine. This requirement means the
proper blade length must be used for the job to be
performed. For normal operation, the boom swing
control lever must also be placed in the FLOAT
position.
The plow motor speed can be adjusted to any speed
in the operating range to obtain the best
performance.
Transport Position
By changing the ground speed setting and the plow
shaker speed setting at the same time, it is possible
to optimize the plow speed for the given soil
conditions. Start with plow shaker control about
midway and adjust the ground drive speed for best
performance (3 to 10% wheel slip). Adjust shaker
speed up or down and note performance increase/

Sprocket Boom (if equipped)
The sprocket boom is the most efficient boom for digging
in light to medium soil. Friction is reduced because the
chain is riding on sprockets and not rubbing on a boom
channel. More power is available for digging when friction
is reduced.
WARNING: Be careful when working near the
side of a trench. Serious injury or death can result
if the walls of the trench fall.
Selecting Correct Tools for the Job
You can increase the digging speed and still get long life
from you 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.
Then, in hard digging conditions, select a high tensile
strength chain, a rock boom, and anti-backflex chain with
rock and frost teeth.
B4049491
Rock Channel Boom (if equipped)
When you make the selection, know the trench width,
trench depth, soil and weather conditions of the job.
The rock channel boom is designed to give support to the
chain when digging in hard or rocky ground or when the
ground is frozen. The design also prevents rocks from
getting between the chain and the boom and gives full
support to the digging chain.
1. Select the boom length.
2. Select the boom type (sprocket or channel).

AU125990 C11A
ATTACHMENTS
Boom Position When Digging
Anti-Backflex Digging Chain
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.
A standard digging chain works fine in some digging
conditions. However, because of the design, a standard
chain’s teeth can rotate back (backflex) when digging in
heavy or rocky ground. When this backflexing action
starts, the teeth do not remain at the correct digging
angle and the trenching speed is reduced.
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.
This machine is equipped with an Anti-Backflex digging
chain. This chain is designed for hard digging conditions.
The side plates of each link are close together. As the
chain leaves the sprocket, each link comes together with
the next and forms a solid digging channel. This action
keeps each digging tooth at the correct digging angle.
IMPORTANT: Correct chain tension is very important. If
the digging chain is adjusted too tight or too loose the
digging efficiency of the trencher is decreased and the
wear of the parts is increased. See Digging Chain
Adjustment in this manual.
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
Chain Strength
The correct chain for the job is very important. Soil
conditions determine the chain needed. 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.
NOTE: Heavy chain has longer wear life than lighter
chain.
Digging chains are rated by tensile strength. For example:
a 22,680 kg (50,000 pound) chain takes a minimum of
50,000 pounds of pull to break.
A19593
Cupped Teeth
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.

ATTACHMENTS
Tooth Arrangements
The tooth arrangement is where and how each tooth is
attached to the digging chain. Use the following
guidelines when selecting tooth arrangements.
1. Install teeth of the same width at equal spaces
around the chain.
2. Use less teeth on the chain when operating in wet
clay or gumbo.
3. Install more teeth when working in sandy loam or
rocky ground.
RT6602040
4. Use dirt drags in sand or loose soil.
Shark/Rock and Frost Teeth
Tooth Combinations
Use Shark or Rock and Frost teeth when the ground is
very hard, rocky or frozen, or when cutting through
blacktop.
Different types and combinations of teeth and dirt drags
can be used in several ways to increase productivity in
different digging conditions. The rock and frost and shark
teeth give good penetration and the cupped teeth help
with soil removal. Try several combinations to find the one
best suited for your area.

ATTACHMENTS
If the Trench Becomes Crooked
10. Decrease the digging chain speed and look at the
tachometer. If the engine speed increases, push the
ground drive creep control forward until the engine
speed is the same as before.
As the trencher is digging it may vary slightly from a
straight line. This can occur if you are digging too fast for
the soil conditions. To straighten the trench, raise the
boom, reverse the ground travel and move the trencher
forward until the digging chain clears the trench. Correct
the alignment of the trencher to the trench and lower the
boom.
Repeat this procedure to reach the best trenching speed.
NOTE: Some hard ground conditions will let you dig a
trench faster by reducing the chain speed.
Cutting A Curved Trench
DO NOT operate trencher
attachment without restraint bar or a crumber.
WARNING:
NOTE: Do not make sharp turns with the boom in the
ground. Sharp turns with the trencher operating will
cause damage to the machine.
A gradual curve can be made by GRADUALLY moving the
direction/speed control to slightly articulate the machine.
Do not make steering corrections, as this will swing the
boom into the side of the trench and undercut it. To cut a
sharp curve with the trencher, see the illustration below.
NOTE: The trencher operates best at full throttle. Adjust
ground speed to keep from lugging the engine.
11. Any steering must be gradual. Do not make sharp
turns with the boom in the ground. Sharp turns with
the trencher operating will cause damage to the
machine.
12. Check the digging chain tension when starting a new
trench in each location. See Trencher Digging Chain
Tension in this manual.

4. Move the throttle to IDLE and stop the engine, apply
the parking brake, and remove the key.
Digging Efficiency
In order to obtain maximum digging efficiency from your
trencher, always keep good sharp teeth at the necessary
spaces. As teeth become worn, replace them immediately.
Maximum Chain Speed
Some ground conditions (mud, etc.) can require a faster
chain speed. Move the chain speed control further from
neutral. It is possible that you will reduce the life of the
digging chain with extended use at higher chain speeds.
Cutting A Straight Trench
To cut a straight trench, stretch a string line parallel to the
proposed trench on the opposite side of the machine
auger. Using the tire as a reference point on the machine,
move the trencher parallel to the string line. Maintain an
equal distance between the tire and the string line and
the trench will be straight.

MACHINE STORAGE
Storage Preparation
Removal from Storage
If the machine is stored for more than 30 days, it is
recommended that the machine be parked inside a
building. If a building is not available, park the machine in
a dry area on planks and cover the machine with a
waterproof covering.
DO NOT start the engine until all of the following steps
have been completed.
1. Remove all protective coverings.
2. Change the fuel filter.
3. Fill the fuel tank with new diesel fuel.
The following storage preparations are good for long term
storage up to one year. After that, the engine should be
started, warmed up, and retreated for an extended
storage period.
4. Remove air from the fuel system.
5. Tighten the engine coolant drain valve. Put coolant in
the engine cooling system and secure the filler cap.
1. Wash the machine.
6. Check the hydraulic oil level.
2. Lubricate all grease fittings.
7. Check the transmission oil level.
3. Paint any areas where the paint has been damaged.
8. Lubricate the machine at all grease fittings.
4. Change the engine oil and oil filters.
9. Remove the Rust and Corrosion Preventative from the
hydraulic cylinder rods and control valve spools.
5. Drain the fuel tank.
6. Put approximately 8 litres (2 U.S. Gallons) of diesel
flushing oil in the fuel tank. Run the engine until the
exhaust smoke is blue-white.
10. Check tires for correct air pressure.
11. Install the alternator drive belt.
12. Ensure the battery is fully charged and then install the
battery.
7. Drain the flushing oil from the fuel tank.
8. Put 15 ml (one tablespoon) of Shell Oil Company VPI
Crystals in the fuel tank.
13. Remove the Do Not Operate tag.
14. Start the engine. It is important that you use the
correct procedure. See Starting the Engine in this
manual for starting the engine.
9. Move all hydraulic controls to release any pressure in
the hydraulic system.
10. Place all controls in the neutral or off position.
15. On the first day of operation after storage, check
overall machine for leaks and check all gauges for
correct operation.
11. Drain the cooling system. Leave the drain valve open.
Do not tighten the radiator filler cap.
12. Put a Do Not Operate tag on the key switch.
13. Loosen the alternator drive belt and remove. Put a
tag on the steering wheel alerting that the belt is
removed.
14. Replace the primary element for the air filter.
15. Cover all exposed hydraulic cylinder rods and control
valve spools with Rust and Corrosion Preventive.
16. Charge the battery. Remove the battery from the
machine and put the battery on a wooden pallet in a
cool dry area. If possible, keep the battery in a
building where the temperature is above freezing, 0°C
(32°F).
NOTE: Check the battery periodically for the correct
electrolyte level. Test the electrolyte with a hydrometer.
When the hydrometer reading is near 1.215 charge the
battery.
