3. Maintenance Intervals
•Maintenance Intervals:
In a modular structure, the Minuteman System Maintenance determines the specific
technical proceedures to be preformed and sets the time interval between the two
maintenance cycles.
For each of the maintenance cycle, the replaceable parts are determined as well.
Further details described in the specific chapters.
•Minuteman System Maintenance K:
To be performed by the customer (in daily or weekly intervals) according to the maintenance
and care instructions as specified in the operating instructions.
The operator must be professionally instructed after delivery of the machine by selling
dealer.
•Minuteman System Maintenance I: (after every 125 hours of operation)
To be preformed an authorized Minuteman Service Center in accordance with the machine-
specific system maintenance.
•Minuteman System Maintenance II: (after every 250 hours of operation)
To be preformed an authorized Minuteman Service Center in accordance with the machine-
specific system maintenance.

4. Batteries & Wiring
•Battery Compartment
•The battery compartment is located under the
recovery tank. The battery compartment can be
accessed for servicing and maintenance by tilting the
recovery tank. Make sure the recovery tank is has
been drained before tilting.
•The battery compartment contains two 12 volt
batteries connected in series.
•Connect the batteries according the battery wiring
diagram to the right.
•The recommended batteries are two 12 volt, 105 Ah
deep cycle battery part number 956712 for the Wet
LeadAcid type or 12 volt 100Ah Gel Maintenance
Free is part number 956100. Do not useAutomotive
or Marine type batteries.
•When changing the type of battery (going to Gel from
Wet Lead Acid or visa versa) the battery charger will
need to be programmed accordingly. See Section 8.1
on Programming the Charger.

5. Recovery Float
•The Recovery Float and Filter is located inside of the tank,
•The filter should be checked after each use and cleaned if needed.
•Remove the three screws and the cover, to access screen float for more extensive cleaning.
•Failure to do so will reduce the vacuum performance of the machine.
•Using the machine without it in place or picking up dry material will damage the vacuum
motor.

Regularly scheduled lubrication of certain machine
parts should be performed to insure trouble-free
operation of the machine. Apply a generous amount
of grease into the fittings on the machine until grease
seeps out around the bearings. Wipe excessive
grease off with a towel.
The grease points are listed below:
1. Rear squeegee caster wheel axle (2)
2. Rear squeegee caster swivel (2)
Apply lubricant to:
1. The rear squeegee pivot points
2. The scrub deck linkages.

7. Charging Indicator
•The indicator will light during
the charging process.
•The red light indicates, the
batteries need a full charge.
•The yellow light indicates, the
batteries have received 80% of
their charge.
•The green light indicates, the
batteries are fully charged.
•The red light is flashing,
indicates the charger has

8.3 Battery Charger Trouble Shooting
(957745 Charger Only)
1. Does the battery charger turn on when plugged into the A.C. outlet?
2. Can you hear the cooling fan turn on? If not, check the A.C. outlet for power.
3. Try a different outlet, if needed.
4. If it still doesn’t turn on, inspect the A.C. cord. Repair if needed.
5. If theA.C. cord is Ok, check to see if the battery connector has been plugged in to
the machine’s connector.
6. Inspect the battery cables. Make sure they are clean and tight.
7. Test the voltage of the batteries; it must be above two volts minimum, before the charger
will turn on.
8. If everything above checks OK, and the charger still doesn’t turn on or doesn’t have any
output, replace the battery charger.
