4 insTallaTion anD oPeraTinG insTrucTions
Digga Trenchers are designed for cutting narrow, straight trenches in the soil prior to laying electrical, telephone and cable lines, or water
and gas pipe. The DIGGA Trencher attaches to the tool bar/quick-attach mechanism of your Machine. Due to this arrangement, thorough
knowledge of the machinery controls is necessary for machine operation. Read and understand your machine operator’s manual for
information regarding machine operation before attempting to use the Trencher. When a Digga Trencher is purchased from Digga or a
DIGGA Dealer/Distributor the frame/attachment is matched for suitability and compatibility to the ow, pressures & load ratings of the original
machine it was purchased for. For tment of the Digga Trencher to other machines you must rst contact your DIGGA dealer and receive written
conrmation to ensure you do not incorrectly t the Cleana Angle Broom to a machine with higher, pressure or rated load capacities than
what the Digga Trencher was designed for. Warranty will be void if the Digga Trencher is tted to an alternative machine without rst
receiving written conrmation from your DIGGA dealer. Exceeding the recommended max ow, pressure, or rated load capacity of the
Digga Trencher as stated on the serial tag will void all warranty.
Check the work site and identify the extent of the work to be carried out and note any possible hazards or constraints, Underground
cables, services etc. DIAL 1100 Before you dig. Review the job at hand and determine the chain type is appropriate for the intended
digging conditions. Ie. Do not use cup teeth in medium to hard conditions, Diggatac is the correct selection.
The Trencher is not a chainsaw and must not be used above ground for cutting, shearing or any other use but what the Trencher has been
designed for.
NOTE: IT IS IMPORTANT TO MAKE SURE THE LOCKING MECHANISM ON YOUR QUICK ATTACH IS
ENGAGED, THEREFORE LOCKING THE ATTACHMENT ONTO THE MACHINE.
SAFETY FIRST!! READ AND UNDERSTAND THE SAFETY INSTRUCTIONS BEFORE BEGINNING ANY
TRENCHER MOUNTING.

DO NOT LOCK THE AUXILIARY HYDRAULICS OF YOUR MACHINE IN THE “ON” POSITION.
FAILURE TO OBEY THIS WARNING COULD RESULT IN DEATH OR SERIOUS INJURY.
SAFETY FIRST!! READ & UNDERSTAND THE SAFETY INSTRUCTIONS BEFORE BEGINNING
ANY TRENCHER OPERATING.
Never lift this product:
● Above the operator’s eye level OR to a height where visibility is obstructed, which ever is lower.
FAILURE TO OBEY THE FOLLOWING PROCEDURES COULD RESULT IN DEATH OR
SERIOUS INJURY.
8. Make sure the couplers are fully connected and locked.
9. Route the hoses in such a fashion as to avoid pinching or chang.
10. Check the Chain teeth are not worn. Ensure all worn parts are replaced. Worn parts will become ineffective and severely diminish the
overall performance of the Trencher.
11. The machine is now ready for use.
TO CUT A TRENCH
1. Before operating the trencher, ensure the Crumber bar is pinned in the locked back position.
2. Raise the Trencher so the trencher is horizontal to the ground, with the trencher at approx 200mm off the ground start the rotation
of the chain. Ensure the chain is rotating freely before engaging full RPM.
3. Take the machine to full RPM. With the machine at full RPM engage the trencher into the ground.
4. It will take approximately 1m of trenching before you can operate at the desired depth. With the Crumber Bar still pinned in the
locked back position slowly crowd the trencher over to the desired depth whilst reversing the parent machine.
5. Once the desired depth has been reached. Raise the trencher, stop chain rotation. Use the pin to lock the Crumber Bar forward in
the trenching position. Lower the trencher and continue.
The Crumber has springs to give constant down pressure on the bottom of the trench in order to scoop all spoil missed in
the initial cut of the chain, throwing it back onto the chain to be carried back to the surface.
WHILE CHAIN IS MOVING ALL BYSTANDERS MUST BE A MINIMUM OF 6M/20FT AWAY. IT IS THE
RESPONSIBILITY OF THE OPERATOR TO ENSURE ALL SAFETY PROCEDURES ARE FOLLOWED

8PM-000005 - Trencher Operators Manual - December 2012
If starting a trench with the Crumber Bar in the trenching position it will take approximately 2m of trenching before you can operate
at the desired depth. Do not apply excessive downward pressure on the Crumber Bar while beginning a trench. This will cause the
spring to over extend as it is going down the rst part of the trench resulting in Crumber failure and damage.
6. The Trencher is designed to operate with the depth adjustable ‘foot’ on the ground. Do not apply excessive pressure to the foot.
Under no circumstances should the front of the machine be lifted off the ground by the Trencher.
● The trencher is designed to cut straight trenches, it cannot be used for cutting trenches around corners. However if desired
a curved trench can be achieved by cutting in a slow wide arc.
● The parent machine is to be reversed when trenching. You cannot trench while driving forward.
● If the trencher stalls while digging, move forward or raise slightly to free the trencher then continue. Do not continually stall the
trencher. Allow the trencher time to cut and clear spoil.
● Never use earth chains when digging in difcult hard ground conditions.
● Always check chain condition and ensure teeth are tightened before use.
● Never continue to dig if the chain begins to jump (due to incorrect style/type of teeth used in harder ground conditions)
CAUTION: DO NOT RAPIDLY ENGAGE FORWARD AND REVERSE OR ON/OFF ROTATIONAL
MOVEMENT TO CLEAR THE TRENCHER. THIS ACTION CAN CAUSE CAVEATATION OF THE
MOTOR AND VOID MOTOR WARRANTY.

REMOVAL AND STORAGE
1. Set the attachment on the ground and follow the standard shut down procedure in your loader operators manual.
2. With the loader OFF, disengage the attachment lock pins, release hydraulic pressure from the auxiliary hydraulic system and
disconnect the hydraulic couplers from the loader.
3. Start the machines engine and make sure that the lift arm is lowered and in contact with the loader frame.
4. Roll the attachment mechanism forward and slowly back up until the attachment is free from the machine.
5. Remove and store the attachment in a dry and protected place. Leaving the Digga Trencher outside will materially shorten its life.
WHEN ATTACHMENTS NOT ON PARENT MACHINE:
It is a requirement of the Australian Work place Health and Safety act 1995 that safe systems of work are employed when handling
any attachments. Complete compliance with Work place Health and Safety issues is compulsory and all due care and attention must
be observed at all times in any method of moving, transporting or storing any such device when not attached to a parent machine. We
recommend attachments are well secured when being moved or in transit and furthermore prior to moving, storing, loading/unloading or
parking it is suggested that the attachment is strapped/secured to a pallet or enclosed in a suitable container to minimise any movement or
loss of the load during such activity. NO responsibility for loss or damage to persons or property in any regard can be attributed to Digga.

Escaping uid under pressure can have
sufcient force to penetrate 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 uid 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.

SCRAPER SHOE REPLACEMENT
SCRAPER SHOE (PLASTIC)
The Scraper shoe is designed to be able to ip end for end when worn. This gives the operator an
extended use before replacing. To either ip or replace the shoe remove the 3 bolts. With a new shoe,
it may be at when purchased. To mould this into an arc form simply place shoe between the jaws of a
vice and over bend , replace bolts – bottom rst.
HEAVY DUTY SCRAPER SHOE (METAL)
The Heavy Duty scraper shoe is designed to be used with the Hydrive XD and the Bigfoot XD.
3. When pressing the new bearing in ensure the drift used is
the correct size. ie; The drift must sit against the outside shell of
the bearing being careful not to damage the ring that holds the
bearing together, make sure the bearing is sitting against the lip on
the opposite side of the nose roller and replace circlip.
NOTE: A HAMMER IS NOT RECOMMENDED FOR THIS PROCEDURE AS IT CAN DAMAGE THE
NEW BEARING.

SEAL REPLACEMENT
Before the seal can be replaced remove
retaining collar and sprocket as shown in
sprocket replacement. Then remove the
key and seal protector. Place a screwdriver
between outside of seal and inside of
housing. Tap gently with a hammer until
the seal can be levered out Fig 1. Inspect
the inside of the housing for damage and
if damaged or burred, clean up with emery
cloth.
Proceed to t the seal by using a large punch
and gently tap the seal into place ensuring
the seal is punched in evenly (see Fig 3). This
is very important as any misalignment could
cause damage to the seal and promote a leak.
The seal must be ush with the end of the
housing. Replace seal protector, key, sprocket
and retaining collar. Rell the planetary with
gear oil (See lubrication for correct amount,
grade of gear oil, and oil lling procedures).
Before the seal can be replaced run
some grease around the inside lip of the
seal for lubrication to the shaft. Ensure
there are no burrs on the shaft between
the end of the shaft and the end of the
housing. File if necessary. Using loctite
243 (or equivalent) run a small bead
around the outside of the seal see
Fig 2.

PLANETARY GEAR OIL
The Trencher Planetary Unit is a sealed Unit. If there is any sign of oil leaks please contact your nearest DIGGA dealer before carrying out
any repairs, as there can be other causes for seal leaks.
The Planetary Drive Unit in the Trencher uses the Gear Oil (Valvoline EPG320) for lubrication of gears and bearings. The unit holds 600ml
of gear oil. The gear Oil should be drained and replaced after the rst eight (8) months of use from purchase. Thereafter every twelve
(12) months or 1000 hours – which ever comes rst. Contact your nearest DIGGA Dealer for Gear Oil change procedure.
● Continuous operating temperature must not exceed 80°c.
● During extended stationary periods (one month or more), the unit should be run monthly to immerse all internals in oil, thereby
preventing corrosion.
● Oil should be changed when hot, to prevent a build up of sludge deposits. Flush interior of unit with uid recommended by oil
companies.
● Check for leaks regularly and if an oil leak is detected contact your nearest DIGGA Dealer for remedy instructions.
● Use only the prescribed oil when relling. Valvoline EPG320 Gear Oil.
● DO NOT mix oil of different viscosity, NOT even those of the same brand.
● NEVER mix mineral and synthetic oils.
● Cleanliness is necessary when changing oil.
