GENERAL COMMENTS
Congratulations on the purchase of your new trencher! Your trencher
was carefully designed and manufactured to give you many years of dependable service. Your trencher will require some minor maintenance (such
as cleaning and lubricating) to keep it in top working condition. Be sure to
observe all safety precautions and maintenance procedures as described in
this manual.
ABOUT THIS MANUAL
This manual has been designed to help you do a better, safer job.
Read this manual carefully and become familiar with it's contents. Remem-
ber, never let anyone operate this trencher without reading the "Safety
Precautions" and "Operating Instructions" sections of this manual. (See
Sections B and G respectively.)
Unless noted otherwise, "right-hand" and "left-hand" sides are determined from the position of the skid steer operator sitting in the seat facing
forward.
SAFETY ALERT SYMBOL
This is the "Safety Alert Symbol" used by this industry. This
symbol is used to warn of possible injury. Be sure to read all
warnings carefully. They are included for your safety and for
the safety of others working with you.
SERVICE
When servicing your trencher, remember to use only manufacturer
replacement parts. Substitute parts may not meet the standards required
for safe, dependable operation.

TRANSPORTING THE TRENCHER
Never drop a boom with a rapidly moving digging chain on the
ground. The force of the trencher may cause the vehicle to move
suddenly and unexpectedly. Have the chain moving slowly, and
lower the boom carefully when starting a new cut.
Use caution when digging on a slope. The natural vibration of the
trencher will make the unit creep sideways downhill. Try to dig with
the trencher in a level position.
Never try to make sharp turns while trenching. The trencher boom
could become wedged in the trench and damaged.
Never attempt to free a stuck chain with the unit running. If the
trencher does become jammed, stop the unit and visually inspect the
situation.
Check the trencher frequently for loose hardware and fittings. The
natural vibration of the unit will cause fasteners to loosen during
operation.

Be sure all lights and turn signals are in working order. Use them as
required.
When parking, park the unit on hard level ground and lower the tren-
cher boom. Block the wheels, and set the parking brake. Shut off the
engine.
Stop the trencher and vehicle before dismounting.

Always wear safety goggles or glasses when working on equipment.
WARNING! Escaping fluid under pressure can have sufficient force to pen-
etrate the skin, causing serious personal injury. Fluid escaping
from a very small hole can be almost invisible. Use a piece of
cardboard or wood, rather than hands to search for suspected
leaks.
Keep unprotected body parts, such as face, eyes, and arms as
far away as possible from a suspected leak. Flesh injected
with hydraulic fluid may develop gangrene or other permanent
disabilities.
If injured by injected fluid, see a doctor at once. If your doctor
is not familiar with this type of injury, ask him to research it
immediately to determine proper treatment.

OPTIONS
Eventually you may wish to dig a trench of a depth or width other
than what your unit was originally equipped to dig. The 617 trencher can
be fitted with optional booms, digging chains, sprockets, and crumber assemblies to allow you to dig a variety of different sized trenches with a
digging chain option of a tooth every station or every other station. The
chart below will give you an idea of the different trench depths and widths a
properly equipped unit is capable of digging. For more detailed information
on trencher options see Sections I & J of this manual.
TRENCH DEPTHS* TRENCH WIDTHS
30" Depth 6.00" 8.00" 10.00" 12.00"
36" Depth 6.00" 8.00" 10.00" NA
42" Depth 6.00" 8.00" 10.00" NA
48" Depth 6.00" 8.00" NA NA
*Trench depths are given with the digging boom at an optimum 65°
diggging angle and the skid shoe touching the ground. Trenches of
various depths can be made by varying the digging angle and raising
the trencher up higher. These methods are less efficient however.
NOTE: The illustrations and data used in this manual were current
(according to the information available to us) at the time of
printing, however, we reserve the right to redesign and change the
trenchers as may be necessary without notification.

MOUNTING KIT INSTALLATION
617 TRENCHER
GENERAL INFORMATION
A mounting kit is required to attach the trencher to the skid steer.
Your trencher may have been shipped with the mounting kit installed. The
following instructions are provided here to help you install the mounting kit
in the case that yours was not installed at the factory.
This manual contains a diagram and parts list of the mounting kits
located in the front of this section. To determine which mounting kit you
need for your skid steer, refer to the chart in Section D. Study the diagram
and familiarize yourself with the names of the various parts. This knowledge will assist you in understanding these instructions. Read the complete
mounting instructions that follow before you begin. Read all safety warnings before operating the trencher.
In addition to the complete trencher assembly which includes the
mounting and hydraulic kit, you will also need a pair of couplers (one male
and one female) to hook-up the hydraulic hoses. The couplers must fit the
male hydraulic hose ends. The couplers must also mate up to the skid
steer's auxiliary hydraulic system couplers. You should be able to purchase
such couplers from your skid steer dealer.
MOUNTING INSTRUCTIONS
1. Remove all shipping banding from the trencher and attaching
bracket(s). Remove any other mounting kit components from their
packaging.
2 . NOTE: The side shift mounting frame may have been shipped already
installed. In the event yours was not installed -attach the side shift
mounting frame to the trencher by sliding the two side shift inner
tubes (part #78824) through the trencher mount lining up one set of
side shift holes and installing the lock pin (part #79113). Attach the
side shift mounting frame to the side shift inner tubes using the four
.75"UNC x 4.50" capscrews and lock nuts provided. (See Figure #1)

GENERAL INFORMATION
The following instructions will help you to mount your trencher on your skid
steer. The trencher uses the skid steer's quick-change attaching system for ease
on installation. Therefore, if you know how to attach the skid steer loader bucket,
attaching the trencher should prove no problem.
You must install the mounting kit prior to installing the trencher. If you have
not installed the mounting kit, turn to Section E and do it now. Remember to read all
safety warnings, decals, and operating instructions before operating the skid steer
or trencher.
MOUNTING INSTRUCTIONS
1. If you haven't done so already, remove the steel shipping banding from
around the trencher and skid.
2. Set the quick-change attaching lock on the skid steer toolbar to the unlocked
position. Lower the skid steer loader arms and tilt the toolbar down low
enough to pass under the top lip of the mounting kit adaptor plate.
3. Following all standard safety practices, start the skid steer and slowly drive it
in back of the trencher. Position the skid steer so that the top of the toolbar
is in under the lip on the adaptor plate. (See Figure #1)

5. Set the quick-change attaching lock to the locked position to secure the
trencher. It may be necessary to raise, lower, or tilt the toolbar in order for the
trencher mount and toolbar to properly align so the locking mechanism can
be activated.
6. With the auxiliary hydraulic system turned off, route the trencher hydraulic
hoses over the top of the mount and toolbar and connect to their proper
auxiliary couplers.
7. Complete the predelivery check list located in the back of this manual (Sec-
tion R). Trencher installation is now complete.

617 TRENCHER
GENERAL INFORMATION
Simplicity of operation is one of the key features of the 617 trencher. The
trenchers themselves have no controls, just a few adjustments to check. It is important however, to be familiar with, and know the controls and adjustments on both the
trencher and the skid steer. Such knowledge is crucial for safe, efficient operation
of equipment. Take the time to learn how they operate now.
SKID STEER
Your trencher mounts to the toolbar / attachment plate of the skid steer. Due
to this arrangement, thorough knowledge of the skid steer controls is necessary for
trencher operation. Read your skid steer owner's manual for information regarding
skid steer operation before attempting to use the trencher.
RAISING / LOWERING THE TRENCHER
Raise / lower the trencher unit by raising / lowering the skid steer loader arms
through their appropriate skid steer controls. (See Figure #1)
CAUTION! Become aware of any overhead power or telephone lines, tree
limbs, etc., that the raised trencher could come into contact
with. Contact with electrical lines could cause serious injury or
death.

TILTING THE TRENCHER
Tilt the trencher unit up or down by tilting the toolbar / attachment plate back
or forward through its skid steer control. We recommend a 60° digging angle for
general trenching as measured from ground level (the horizon). (See Figure #2)

Your trencher has an adjustment to shift the whole unit to the side on its own
mount. To shift the unit sideways, first remove the locking pin from the back of the
unit.
Lower trencher until trencher frame is resting on the ground, then counterrotate the tires so that the skid steer moves in a sideways motion. Continue moving
until side shift holes are aligned and replace locking pin.
IMPORTANT: Always reinstall the locking pin to prevent the trencher from
shifting sideways during operation.
NOTE: Slight shifting of the trencher from side to side may be necessary to
align the side shift holes for reinstalling the locking pin.

617 TRENCHER
STARTING AND STOPPING THE TRENCHER
Power to the trencher is supplied by oil from the skid steer auxiliary hydraulic
system, which passes through the hydraulic hoses and into the trencher's hydraulic
motor.
The trencher unit itself does not have an on/off control but is operated by the
skid steer auxiliary hydraulic control mechanism. The start the trencher, engage the
auxiliary hydraulics. (This is usually done by a pedal located in the middle of the
skid steer floor. See your skid steer owner's manual.) To stop the trencher, disengage the auxiliary hydraulics.
TRENCHER SPEED CONTROL
Again it may be noted that power to the trencher is supplied by the skid
steer's auxiliary hydraulics. Trencher speed and power are determined by the flow
of oil coming out of the auxiliary system, which in turn is dependent upon skid steer
engine speed. To increase trencher speed, increase skid steer engine speed, to
decrease trencher speed, decrease skid steer engine speed.
When first starting a trench throttle down the skid steer engine to half throttle.
This will reduce the shock to the skid steer and trencher when the digging teeth first
contact the ground. Once the trench is started, set the engine back to full throttle.
For general use operate the trencher with the skid steer engine at full throttle
to provide maximum power to the auxiliary hydraulics and thus the trencher.
AUGER HEIGHT
The auger is fixed to the trencher mainframe and has no separate adjustment. To raise the auger, raise the trencher as previously described. This will raise
the auger and thus leave the dirt or spoil closer to the trench.
Lowering the trencher will cause the auger to lower, moving the spoil away
from the trench. The built-in skid shoe on the 617 trencher will prevent the auger
from being lowered to the extent that the auger itself starts to dig in the ground as
this will greatly reduce efficiency.

617 TRENCHER
It should be noted that raising or lowering the trencher to change the auger
height will also change the trenching depth. You will need to compensate for this by
changing the tilt of the trencher down or up accordingly. (See Figure #3)

CRUMBER SHOE/BAR ADJUSTMENT
The purpose of the crumber shoe is to keep any loose dirt in the trench close
enough to the digging chain so that the digging teeth can grab it and remove it. This
will give you a cleaner finished trench. Your trencher has an adjustable crumber bar
that can be lengthened or shortened to bring the crumber shoe closer or farther from
the digging chain.
To adjust the crumber bar length, loosen the two jam nuts found at the end of
the mainframe crumber bar tube. Slide the bar in or out to achieve the desired
spacing (we suggest a distance of about 4" between crumber shoe and digging
teeth for best overall results). Tighten the set screws and jam nuts when finished.

CHAIN TENSION ADJUSTMENT
When trenching, the digging chain tension should be adjusted so that
the chain is as loose as possible, without jumping off the sprocket or idler
wheel. To do this, an adjustment is provided on the digging boom.
These booms have an adjusting bolt on each side at the trencher end
of the boom. The head of the bolts are kept from rotating by special tubes
welded onto the mainframe. The end of the bolt rests in a tube welded to
the boom. Each bolt has a jam nut and a .75" hex nut on it. To tighten the
chain, "back off" the jam nut from the regular nuts. Now turn the standard
nuts off the adjusting bolts. This will push the boom out and thus tighten
the chain. Retighten the jam nut when finished. To loosen the chain, follow the same procedure, except turn the hex nut onto the adjusting bolt.

CAUTION! Never work on, or make adjustments to any part of the tren-
cher while the unit is running. You could get caught in the
digging teeth which could cause severe injury or death.
It is common for your trencher to need its digging chain tightened
after the first 10 to 20 minutes of operation as the chain and sprocket seat
themselves.

GENERAL INFORMATION
The design of your trencher makes it relatively simple to use. With
the help of the information in this section and a little practice you should
become proficient in it's operation in no time. Observe the following points
to obtain the best results with the least amount of wear on the machine.
Read the "Safety Precautions" section of this manual before you begin.
(See Section B)
CAUTION! Operate the trencher only when seated at the skid steer con-
trols.
Do not operate the skid steer without proper ROPS (Roll-Over-
Protective-Structure), seat belt, and hard hat.
Pay attention to the job at hand. Be alert to the possibilities of
others in the work area.
Never let anyone work around, or perform maintenance on the
trencher while it is running.
Always use a crumber assembly on the trencher.
BEFORE YOU START TRENCHING
Before any excavating is started, it is always a good idea to plan out
the job first. Various things need to be considered and taken into account
prior to the actual trenching. The operator should inspect the job site and
take notice on any potential hazards in the area. He should have a complete
understanding of the task he is expected to perform. Figure out what will
be done with the spoil (excavated soil), will it be used to backfill or be
trucked out? What are the soil conditions like? Will you have to work
around others? Etc.
WARNING! Check the prospective trenching area for hidden utility lines
before operating the trencher. Contacting a utility line with the
trencher could cause electrocution resulting in death. Call all
utility companies and have them plot out all their lines first. If
you damage a utility line, shut off the equipment at once and
contact the affected utility immediately.
Once you have become familiar with the job site and understand the
job requirements it is time to set up for the actual trenching. Check the soil
type (hard, soft, rocky, etc.) and the trenching requirements (how deep,
wide, etc.). Install the proper digging chain, sprocket, boom, crumber bar
and shoe for the job at hand. Information on chains, sprockets, booms,
crumber bars and shoes may be found in Sections I and J.

SKID STEER TRENCHERS
Locate the trencher on the mount with the side shift mechanism (as
explained earlier in this section) where it will be most efficient and easy to
use.
Mark off the area to be trenched out. This can be done with powdered lime, chalk, or a guide string and stakes. Block off the area from all
bystanders if possible.
STARTING THE TRENCH
Position the skid steer with the trencher boom directly over the center
of the trench layout. It will take about 4' of trenching before the trencher
will be able to operate at the desired level, so plan for this and position the
trencher about 4' behind where you want the actual trench to start.
NOTE: The skid steer is driven in
trench driving the skid steer forward.
Raise the trencher with the skid steer loader arms and tilt the trencher
at a 45° angle. (See Figure #6) Position the unit so that the digging teeth
are just above ground level.
Set the skid steer throttle at half speed. Start the digging chain by
engaging the skid steer auxiliary hydraulic system.

Raise the trencher so that the auger rides above the ground level to
leave the spoil beside the trench. The higher the auger, the closer to the
trench the spoil will be placed. You may find that it generally takes less
power to run the digging chain if the auger runs 3" - 6" (inches) off the
ground, and thus increasing the potential footage of trench produced per
hour. The higher you want the auger, the more vertical you will have to tilt
the trencher to achieve the same trench depth. (See Figure #10)
FIGURE #10
TRENCH
With the desired trench depth reached, advance the skid steer throttle
to the desired engine RPM (we suggest full throttle for maximum digging
power). Continue creeping the skid steer in reverse. Monitor the skid steer
hydraulic oil pressure and temperature gauges as you trench. If hydraulic
oil temperature or pressure gets too high, reduce skid steer creeping speed
to reduce the load on the auxiliary hydraulic system.

IMPORTANT: Trying to trench at a speed faster than the auxiliary hydraulic
system can handle could cause the trencher to stall. Continued stalling in a
short period of time can cause excessive oil temperature which can lead to
pump failure. Do not try to trench too much too quickly. If oil temperature
becomes too hot, stop the trencher and allow the oil to cool.
STALLING THE TRENCHER
If the trencher stalls while digging, move the skid steer forward
slightly to free the trencher. You may be able to free up the digging chain
by changing its direction of travel with the auxiliary hydraulic controls.
Repeated stalling of the trencher will cause oil to overheat rapidly and
should be avoided.

SKID STEER TRENCHERS
TURNING WHILE TRENCHING
Gradual turns can be made while trenching. However, the tightness
of the turn is directly proportional to the angle and length of the boom. In
other words the greater the angle of the trencher boom to the ground level,
the sharper the turn that can be trenched. (See Figures #11 & #12) Also
the shorter the boom length the sharper the possible turn. Remember, the
greater the increase in boom angle the higher the unit will have to be raised
out of the trench to keep a unified trench depth. Shallow boom angles will
severely limit turning ability.
IMPORTANT: Turning too tightly while trenching will cause the trencher to
jam in the trench and stall, leading to excessive oil temperatures. Turning
too tightly can also cause the trencher boom to bend. Take it easy when
turning. Proceed slowly with caution.

MAKING SHARP TURNS
To make sharp turns and 90° angles you will have to dig two
trenches. Dig the first trench as you normally would. Then reposition the
unit and dig the second trench at the appropriate angle. Be sure to take
into account the extra lead-in space needed for the trencher to get down to
the desired trench depth. (See Figure #13)

RECOMMENDED DIGGING ANGLES
A 90° digging angle is recommended for use in rock and frost conditions, and when trenching sharp corners. The 90° angle reduces excessive
side pressure on the boom and digging chain when trenching corners. (See
Figure #14)
A 60° - 65° digging angle is recommended for normal trenching. At
this angle there will be less carry-over, and a cleaner trench bottom can be
maintained than at a 90° angle. (See Figure #14)

reason, YOUR SAFETY! There are a few instances where
removal may be necessary however. In these cases operate
with extreme caution. Reinstall the crumber bar and crumber
shoe as soon as possible.
You can use your trencher to dig under obstacles such as sidewalks.
To do so, remove the crumber shoe and bar assembly and start your trench
as before within a foot of the sidewalk. With the crumber bar and shoe
removed you can start the trench vertically without any lead-in space.

ENDING A TRENCH
When you have dug your trench, remember that the trencher boom is
at an angle, and that you must continue trenching until the end of the boom
has dug past the proposed end of the trench. Once the end of the trench
has been dug, keep the trencher running and lift the skid steer loader arms
to lift the unit clear of the trench. When the trencher has cleared the
trench, disengage the auxiliary hydraulics to stop the trencher. Drive the
skid steer away from the trench.
TRANSPORTING THE TRENCHER
When transporting the trencher, remember to keep the trencher as
low to the ground as is practical. The lower the trencher rides, the more
stable the skid steer will be. You do not want the trencher so low that the
digging teeth touch the ground in rough terrain. Shut off the trencher before moving it away from the trench. Never transport the trencher around
the job site or anywhere else while the digging chain is moving.
TRENCHER PERFORMANCE
Remember that your trencher's performance is directly related to the
power available at you skid steer's auxiliary hydraulic system. If the trencher seems to lack power or speed, it may be due to your skid steer's lack
of sufficient auxiliary power.
Trencher performance is also related to how well it's maintained,
digging tooth wear, and type and size of digging chain, crumber boom and
shoe used. For more information on proper maintenance and chain wear
see Section L. For information on chain, sprocket, boom, and crumber
options see Sections I and J. If problems arise see "Trouble Shooting"

GENERAL INFORMATION
This section is devoted to digging chain options for your trencher. In
it you will find a listing of all the chain options available. You will also find
information on replacement parts, chain assembly, and chain conversion.
These options will increase the flexibility of your equipment, and make your
trenching job easier.
There is some basic information about the trencher and it's digging
components that you should know before you try to order any options. This
information is given here for your convenience. With it you will be able to
better understand the rest of this section.
CHAIN PITCH
J
The digging chains may be divided into groups by pitch. The pitch of
the chain is the distance between the centers of the holes in the chain links
(See Figure 1). The word pitch can also be used to describe the length of
the chain.
FIGURE #1 FIGURE #2
8 PITCH OF CHAIN
DISTANCE BETWEEN HOLE
CENTERS = PITCH
The 617 Trencher has a heavy weight chain with a tensil strength of
50,000 pounds and a pitch of 2.00".
There is one thing that you must understand about chain pitch. You
can not intermix components of different pitches. You cannot substitute
chain links of different pitches in a digging chain. Nor can you use a digging chain of one pitch, with a driver sprocket of a different pitch. Attempting to do so will cause the chain to "jump" off the sprocket continuously.

DIGGING CHAIN OPTIONSDIGGING CHAIN OPTIONS

COMPONENT SIZE
The size of the digging component is based on the depth of the
trench it will dig with auger at ground level and a 60° boom digging angle
(See Figure 3). For example, a 36" boom is not necessarily 36" long. The
36" length means it will dig a trench 36" deep with the augers in their float
position and at a 60° digging angle.
FIGURE #3
J
36" BOOM

DIGGING STATIONS
Digging chains are made up of a series of individual links pinned
together. Every link has a special "Digging Station" link. These links are
designed so that the digging teeth can be attached to the basic chains (See
Figure 4). Digging chains may be purchased in any length, with or without
teeth. All chains, teeth, spacers and assorted digging hardware may be
purchased separately.

This completes the basic information on digging chain options. The
rest of this section contains specific information on digging chains and parts
available, complete with part numbers. Again it may be noted that these
options are designed to increase the flexability of your equipment and to
make your trenching jobs easier. We offer them to better serve your trenching needs.

2.00" PITCH DIGGING CHAIN ASSEMBLIES
GENERAL INFORMATION
This page contains a listing of all of the 2.00" pitch digging chain
assemblies offered for your trencher. Each chain assembly comes with all
necessary teeth and spacers already installed. Just thread the chain onto the
trencher and fasten the two ends together with the pin and keeper pin included
in the assembly. A crumber shoe of the appropriate width is also included in
the chain assembly.
Before you order a new chain, be sure to check for compatibility with
corresponding components. You may need to order more than just a chain
assembly. You must use a digging boom of the same digging depth as the chain.
The crumber bar must also be of the same digging depth. The digging sprocket
must also be of the same pitch as the chain. All of these components must
match for the trencher to function properly.
Bare 2.00" pitch digging chain (without teeth, spacers, or hardware) can
be ordered in any desired length under the part number 79018. Just use this
number and then specifiy the length desired in pitches (example, 54 pitches of
chain would be needed for a 36" boom).

2.00" PITCH CHAIN REPLACEMENT PARTS
GENERAL INFORMATION
You can purchase individual chain links and pins for your trencher.
These can be used to repair a damaged chain, or lengthen and modify an
existing chain. Below is a diagram of the chain’s basic components with
their descriptions and corresponding part numbers. Use these numbers
when ordering. You can also order a complete bare chain (without teeth
and spacers) in any length desired. The chain is ordered under part number
79018 for 2.00" Pitch. Just specify the length you want in pitches. (See
“2.00” PITCH DIGGING CHAIN ASSEMBLIES” chart located in this section.)
When pinning links of chain together, first tap the pin through the
connector link with the perfectly round holes and then on through the inner
link. Place the second connector link in position, you will note that the end
of the pin has one side flattened. Rotate the pin until its flat side lines up
with the corresponding flat side of the connector link hole and tap the pin
on through. Place the chain keeper pin into the hole at the end of the main
pin and tap down tight. Finally, bend the end of the keeper pin over to
secure it in place.

2.00" PITCH DIGGING TOOTH STATION SEQUENCE
GENERAL INFORMATION
Every second link on a digging chain is a special link called a digging
station. These digging station links are designed so that digging teeth can
be bolted onto them in a variety of configurations. It is the number and the
make up of these different digging stations that make each chain unique.
The following tables show the number of digging stations there are in
each available 2.00" pitch digging chain. The digging tooth make up of
each digging station is given in code. The key to the code is located at the
below. Thus these charts will tell you what kind of digging tooth arrangement is at each digging station on each digging chain assembly. The actual
parts break down on each digging tooth arrangement is shown on the "Digging Tooth Station Break Down" diagrams located in this section following
the charts.

2.00" PITCH DIGGING CHAIN WIDTH CONVERSIONS
GENERAL INFORMATION
Digging chains can be modified to dig trenches in a variety of widths. By modifying an
existing chain, it can be used to dig the width you want and thus save going the expense of a whole
new digging chain assembly. This can be a considerable cost savings, however it is more work
than just installing a new digging chain assembly.
The information given below is a complete listing of all the possible chain width conversions
for 2.00" pitch chain for your trencher. Included in the listing is a break down of all the parts
(including part numbers and quantities) needed to make the conversion. Simply install the new
parts (and rearrange the old parts) so that the finished chain construction follows that described
in the “Digging Tooth Station Sequence” chart and the “Digging Tooth Station Break Down”
diagrams for 2.00" pitch chain (located elsewhere in this section).
It should be noted that this information only applies to modifying chains of the same length
and pitch. All components must be of the same pitch. You cannot intermix components of different
pitch.

MAINTENANCE
GENERAL MAINTENANCE
GENERAL INFORMATION
Your trencher was designed to be virtually maintenance free. Very
little effort is needed to keep it in top condition. It is however important to
follow these procedures to get full performance and longevity out of the
trencher.
LUBRICATION
The only lubrication your trencher needs is the greasing of the
headshaft end bearing. The bearing should be lubricated with an SAE multipurpose grease every 8 hours of operation. A grease zerk is installed in the
bearing to facilitate this task.
NOTE: Not all trenchers require lubricating of the headshaft bearing. Some
units have a sealed bearing that requires no maintenance. These units can
be identified by the absence of a grease zerk in the bearing.
IMPORTANT:
parts such as the digging chain or the idler wheel will only attract dirt, resulting in increased wear.
EVERY 40 HOURS OF OPERATION
Every 40 hours of operation the trencher should be inspected for
loose nuts, capscrews, bearings etc. Tighten as required, replace where
necessary. Clean equipment of all dirt, oil, grease, etc. This will assist you
in making visual inspections and help avoid overlooking worn or damaged
components. Keep all safety decals clean and legible. Replace if damaged
or worn.
DIGGING TOOTH REPLACEMENT
Sharp teeth are important to good performance. When teeth wear
out, production will drop sharply, increasing wear and tear on other components.
Cup teeth wear on the tip and side bulge in varying amounts. Wear
patterns change with different digging conditions. The following patterns
and captions are approximate and should be used as a guide to help you
determine your own best cost/benefit tooth replacement time. Normal
replacement should be made between 30% and 60% reduction in performance. Replacement is a bolt-on procedure. See Section J.
DO NOT lubricate any other part of the trencher! Lubricating

STORAGE
617 TRENCHER
GENERAL INFORMATION
The following storage procedures will help you to keep your trencher
in top condition. They will also help you get off to a good start the next
time your trencher is needed. We therefor strongly recommend that you
take the extra time to follow these procedures whenever your trencher will
not be used for an extended period of time.
PREPARATION FOR STORAGE
1. Clean the trencher exterior thoroughly, removing all mud, dirt, and
grease.
2. Tighten all loose bolts, nuts, and set screws.
3. Touch up unpainted and exposed areas with paint to prevent rust.
4 . Coat the digging chain with a thin covering of oil. Operate chain for a
short period to work the oil into the pins.
5 . Store the trencher in a dry and protected place. Leaving the trencher
outside, exposed to the elements will materially shorten its life.
6 . Inspect trencher for visible signs of wear, breakage or damage. Order
any parts required and make necessary repairs to avoid delays when
starting next season.
7 . Replace operating decals if damaged or in unreadable condition.
REMOVING FROM STORAGE
1. Remove all protective coverings
2. Check hydraulic hoses for deterioration and if necessary, replace.
3. During cold weather, operate the trencher slowly for a short time
before placing the unit under full load.

TROUBLE SHOOTING
617 TRENCHER
GENERAL INFORMATION
Your trencher was designed to be as simple and as trouble free as possible.
The purpose of this section is to help you in the event that a problem does develop.
Why we cannot possibly cover every problem that might occur, you will find that
those that are most common are covered here.
PROBLEM: Digging chain will not turn
POSSIBLE CAUSE AND REMEDY:
1. Quick coupler not completely engaged. Check to see that all couplers are
matched pairs and engaged correctly. Check coupler hook-up information
(See Section E) for proper hydraulic hose routing.
2.
3.
4.
5.
6. Hydraulic motor failed. Be sure you have hydraulic flow to the motor. If oil
7.
Quick coupler failure. Check couplers for dirt, rust, or other contaminates
that could effect coupler engagement. Clean or replace couplers as needed.
Obstruction in hydraulic hose. Remove hydraulic hoses and couplers one at
a time and check flow through hose by blowing through the hose or by pour-
ing hydraulic fluid through the hose. Clean or replace hose as needed.
Skid steer relief valve stuck open. Have relief valve serviced and checked by
an authorized dealer.
Skid steer auxiliary valve not operating properly. See skid steer operator's
manual or dealer for information and help.
flow to motor is good, but motor will still not turn when detached from trencher
headshaft, remove motor and have it serviced or replaced as needed.
Headshaft bearings failed. Inspect headshaft bearings for free movement.
Check for binding or foreign matter jamming bearing. Clean or replace as
necessary.
8.
Boom end bearing failed. Inspect boom end bearing for free movement.
Check for binding or foreign matter jamming bearing. Clean or replace as
necessary.

9. Digging chain to tight. Digging chain should only be tight enough to remain
on sprockets while turning under load. Their should be some sag in the
chain. If too tight, loosen chain by the adjusting nut(s) on the boom.
10.
11.
PROBLEM: Trencher does not dig fast enough
POSSIBLE CAUSE AND REMEDY:
1.
2.
3.
Sand build-up in tooth root of sprocket. Sand can build up in the sprockets
effectively increasing the chain tension. Raise the boom out of the ditch and
reverse the digging chain on the trencher, then run the trencher out of the
trench to clear the sprockets. Reinstall the chain in its correct digging direc-
tion and readjust chain tension.
Digging sprocket clamp loose on headshaft. Observe if the headshaft is
turning. If shaft is turning but sprocket is not, stop the trencher and tighten the
sprocket clamp.
Digging teeth worn. See maintenance Section L in this manual. Inspect
teeth and replace as needed.
Skid steer relief valve set too low. See skid steer operator's manual and or
dealer for proper relief valve service and adjustment.
Quick coupler or hose restriction. Inspect couplers and hoses for dirt, rust,
and other contaminates and repair or replace as needed.
4. Hydraulic system over heating. Shut the trencher and skid steer down and
allow oil to cool. Repeated stalling of the trencher will cause the oil to over
heat. Avoid excessive stalling.
5.
PROBLEM: Hydraulic oil over heating
POSSIBLE CAUSE AND REMEDY:
1.
Cutting a ditch size beyond the ability of the skid steer. Your trencher is
powered by oil from the skid steers auxiliary hydraulic system. The horse-
power transmitted through the auxiliary hydraulics is substantially less than
that of the engine.
Skid steer relief valve set too low. See skid steer operator's manual and/or
dealer for proper relief valve service and adjustment.

2. Quick coupler or hose restriction. Inspect couplers and hoses for dirt, rust,
and other contaminates and repair or replace as needed.
3. Motor or hose size not balanced to skid steer. A hose or a motor that is too
small can cause added internal friction and resultant heat build-up. Check
mounting kit parts list and diagram (See Section E) for proper hose size and
type.
4.
Skid steer not equipped with oil cooler or sufficient sump capacity. Check
with your skid steer dealer for information and availability of auxiliary cooling
and sump kits. Install if available. If not available stop skid steer and tren-
cher and allow them to cool when they get too hot.
