servicing the UltraGrind
Proper maintenance of the UltraGrind is the
responsibility of the owner and/or the operator.
Be sure to go through this checklist on a regular
basis:
Check oil level.
Check and clean air and dust filters.
Keep machine clean and lubricated.
Clean entire machine after each use, including
under the gear drive assembly—engine must be
cool before water is used to prevent warping and
other damage.
Clean carburetor air filters after four hours running
time, and clean or replace daily before operation.
Check for wear on drive plates and flex hubs daily,
replace if damaged.
Promptly report any damaged or worn parts to
supervisor.
Servicing and adjusting of the propane fuel system
should only be done by a trained, authorized
professional.
f. engine maintenance meter
This multi-function meter acts as a preventive
maintenance tool, which benefits you with increased
fuel economy, less down-time and longer engine life.
The meter’s displays are:
Hour meter: Displays total run hours when machine
is off.
tachometer: Indicates engine RPM during operation.
service alert: The display flashes to alert you to lube
and change the oil at 25 hour intervals. The service
alert only flashes during operation and it warns
you to change the oil for only two hours. After the
two hours is reached, the alert will automatically
reset to the next 25 hour interval. Therefore, it is
recommended that a separate maintenance log be
kept to track oil changes.
maintenance log be kept to track oil changes.
Remember that being safe is a full-time, every
day job. follow all information posted on the
machine and the lpG tank.
never allow anyone to operate this machine
who has not read or cannot understand the
given instructions.
G. troubleshooting the electrical system
1. Check all wire connections for obvious
problems. Remove LPG tank, then remove
battery box cover. Check all connections
visibly and physically. If any “loose”,
damaged or unconnected wires are noticed,
replace or repair as needed.
2. Check the battery posts and wires. Always
wear a face shield, safety glasses and
protective clothing when working around
a battery. The gases can be explosive and
the acid is highly corrosive to metals, cloth
and ALL HUMAN TISSUE (skin, eyes, etc.)
If the battery post(s) are corroded, remove
the wires and clean posts and wires.
Applying some axle grease on the posts
of the battery after they are cleaned will
slow down the battery corrosion process.
If nothing obvious is noted, a more detailed
investigation is warranted. Before any such
troubleshooting begins, the following things
should be done:
a. Replace propane LPG tank with one from
a machine that runs.
b. Charge the battery or provide an absolute
source of 12 volt DC power capable of
50 amperes total output. (A pair of good
jumper cables from your car or truck
battery will suffice.) Equip yourself with
an inexpensive 12 volt test light.
c. If the trouble seems to be in the electrical
control equipment, you may disconnect
the starter from the system so as to check
the system without spinning the engine.
d. Battery rundown. A common problem
is letting the battery run down. What
usually happens is that it takes the crew a
few jobs to get used to the whole system,
so the machine is stopped and started
quite often. Key left in On position, when
engine is turned off, will result in battery
running down—dying.
never attempt to adjust the fuel system of a
propane engine! if equipped with an emission
monitoring or controlling system, never
attempt to disconnect or circumvent it.
promptly report problems to supervisor.
