PM-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 difcult 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.
