11. Replace spark plug wires and any covers removed. Fill
reservoir to "max" line with hydraulic oil.
12. Follow hydraulic system bleeding instructions and
inspect for leaks before putting unit back into service.
Hydraulic System Bleeding
WARNING!
If air is present in the hydraulic
system, such as after a fluid or filter change,
machine controls may be unresponsive or erratic.
Use extreme caution when operating unit until it is
fully bleed of air.
1. Block front tires and lift rear wheels off ground to prevent
machine from moving while drive is engaged. Do not use
park brake.
2. Ensure reservoir is filled to max line and start engine at
low idle.
3. Watch reservoir level, shutting off machine when it drops
to "min" level line.
4. Refill the unit and restart engine, again watching for oil
level to drop. Note: level may drop very quickly at first,
triggering the low oil light on the dash.
5. Throttle up engine once level stabilizes at idle. As you
check and add hydraulic oil, begin to engage hydraulic drive
levers. Run both forward and backward to circulate oil in the
system. Note: shutting down and restarting the engine will
allow for faster bleeding.
6. Move the hydraulic cylinders by moving all 3 control
handles. Watch for moving attachments.
7. When oil level stabilizes and controls respond consistently
unit can be dropped to the ground and driven.
8. Drive unit carefully; check hydraulic oil level often. Do not
overfill.
Electric System
Fuse Location
1. Main fuse for the machine is located at the battery under
the main rear cover. Note a second fuse is in the same
locatoin for powering the optional laser grading system.
The main system fuse and laser system fuse are both a 20
amp ATC style fuse.
2. A secondary fuse is located under the dash for the
auxiliary power system. It is a 7.5 amp ATC style fuse.
Relay Location
1. There are 2 relays under the dash of the machine.
• The left one powers the cooling fan for the hydraulic system.
• The right one powers the low hydraulic oil indicator light.
Battery Inspection/Jump Starting
1. The battery is located under the main rear cover.
2. Disconnect laser grading system and any other
electrical accessories.
3. Ensure terminals are tight and clean.
4. Battery should have 12.4v minimum reading with key
switch off.
5. Replace with like size and capacity battery.

Note: The ABI Force fuel system contains emissions related
components as regulated by the US EPA and California Air
Resources Board. Any modification of emissions related
components is not permitted and may violate the law.
Replacing the Fuel Filter (every 200 hours)
1. Remove Left side cover.
2. Locate filter in front of engine under frame rail.
2. Remove clamps and replace with Kohler PN 25 050 42-S or
exact match only.
