Troubleshooting/FAQs
Issue / FAQ Resolution/Answer
Ensure the start up sequence has been followed (Page 11).
My machine will not start
I can’t activate the Hydraulics
Immobiliser pin from factory is 1945
If machine still will not star t contac t dealer
There are many reasons as to why your 2Go may not work when pressing the
button on the switch panel. Here are some of the possible reasons:
• If the left hand pod is lifted and put back down when machine hydraulics are
“on”, machine hydraulics will disable and not function again until side pod
down and machine in neutral.
• The left hand pod is in the raised position
• There is a fault on the keypad
• Engine isn’t switched on
• If there is an error on the machine and an error code is displayed on the LCD
screen – which would inhibit the hydraulics
• If none of the above, contac t dealer
.
Can I open the Quick Hitch with the
attachment on the ground?
Why is there an audible buzzer in the cab
when I’m lif ting a large load?
Can I disable the lif t overload warning
indicator when not object handling?
The Quick Hitch can be opened with the attachment on the ground. Follow the
instructions previously (Page 13) and at step 4 follow 4a-4b
The lif t overload warning sys tem has detected a load that is near the limits of
the machine, reduce load to prevent machine overturn
To disable lif t overload warning indicator when not object handling press button

Troubleshooting/FAQs
Issue / FAQ Resolution/Answer
500hrs Greasing – Does it mat ter if
greased every day?
No, this only prolongs the life fur ther
500hrs Greasing – Do the bush need to be
replaced at 500hrs?
500hrs Greasing – After the first 500hrs
does the bush then need greasing daily?
500hrs Greasing – Without daily greasing
what cleans all the dir t out of the bush?
Can you dig to dozer?
Why do the tr acks tread look different to
other tracks?
No, just grease and continue work
No, the bush wont need grea sing until the next 50 0hrs
Machine is fitted with a one way seals stopping dirt entering the bush,
but allows old grease out when greasing
Digging to dozer can not be done while machine dig end is central to the dozer.
To dig to dozer slew machine over to the side then use the boom swing to
offset the boom enabling digging up to the dozer
The tread pattern on the tracks is intentional to give the below benefits:
• The Bridgestone tracks will last longer than any other brands
• The reduction in rubber retains life span but reduces waste material
• Reduces lateral slippage, safer operation when traversing slopes
• Allows ef ficient mud release for better grip and less cleaning
• Provides good ride comfor t

Are the old 8040 -8065 at tachments
compatible?
The pick up geometry has changed to enable compatibilit y with competitor
