Manditory Periodic Maintenance; Troubleshooting - NSS Enterprises Wrangler 2012 AB Manuel De L'opérateur

Battery Do's and Don'ts:
You do not have to fully discharge the batteries
•
before charging. They do not have a "memory".
Plug the charger in anytime the machine is not in
•
use.
• NEVER let the electrolyte level fall below the tops
of the plates (flooded cell batteries). This will
damage your batteries almost immediately, and
void the battery warranty. They can tell if this
happened.
NEVER refill the batteries with well or tap water
•
(flooded cell batteries).
NEVER overfill the batteries (flooded cell batter-
•
ies).
NEVER let the batteries sit discharged overnight
•
(or between shifts).
ALWAYS check the electrolyte level about every 3
•
or 4 charge/discharge cycles BEFORE CHARGING.
ALWAYS refill the batteries with distilled water (if
•
needed) AFTER CHARGING.
ALWAYS fully recharge the batteries after use (un-
•
til the green LED comes on).
ALWAYS equalize the batteries (Flooded only) ev-
•
ery 30 days.
Opportunity Charging
Opportunity charging is charging the batteries when
an opportunity presents itself, such as during breaks,
and is done in addition to a full charge cycle.
Opportunity charging is recommended, as this extra
charging time will help raise the operating voltage of
the batteries, and will help ensure maximum runtime
and cycle life. When opportunity charging, equalize
weekly.
Monthly Maintenance (or every 100hrs)
Clean the battery terminals.
•
• Clean the seal between the Lid and the Recovery
Tank.
Washing Instructions
CAUTION - DO NOT SPRAY WATER ON ANY
PART OF THIS MACHINE, MACHINE COMPONENTS
COULD BE DAMAGED.
• Wipe down the machine's exterior surface with a
damp cloth.
All other servicing should be performed by an autho-
rized NSS Service Representative.
Mandatory Periodic Maintenance
It is mandatory that the following maintenance proce-
dure be performed at the described interval. Failure
to perform this procedure may result in poor machine
performance, component damage and failure. This
procedure should be performed by an NSS authorized
distributor or service center. Repairs not performed by
an unauthorized company will void the machine war-
ranty. If you require assistance finding an authorized
service center, contact NSS Enterprises.
After every 450-500 hours of operation you must
•
inspect vacuum motor carbon brushes for wear.
Replace the vacuum motor carbon brushes when
they are 7/16 in. [11 mm] in length.
After every 650-700 hours of operation you must
•
inspect the brush motor carbon brushes for wear.
Replace the brush motor carbon brushes when
they are 1/2 in. [13 mm] in length.
Wrangler 2012 DB only - After every 650-700
•
hours of operation you must inspect the drive mo-
tor (transaxle) carbon brushes for wear. Replace
the drive motor (transaxle) carbon brushes when
they are 3/8 in. [9 mm] in length.
