Wrangler 2016 AB, Operation Manual

After every 

450-500 hours

 of operation you must inspect 

vac 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 drive motor (transaxle) carbon brushes for wear. 

Replace the drive motor (transaxle) carbon brushes when 
they are 3/8 in. (9 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.

Battery Charger

The onboard battery charger supplied with this 
machine is capable of charging lead acid batteries 
from 185 to 350ah capacity.  There is no need to 
change algorithms or settings based on battery 
manufacturer, or battery size. 

The charger can also be set to charge flooded (wet) 
cell, AGM, or Gel batteries.  LED’s on the charger 
indicate which type of battery the charger is set to 
charge.  One setting is for Flooded and AGM 
batteries, the other setting is only for GEL batteries.  

Depending on the battery charger model, the charger 
can operate on 100/115/230 VAC 1ph 50/60 HZ 
power, and will automatically detect these input 
voltages.  Before connecting the battery charger to 
power, check the label on the battery charger to verify 
the proper input power. 

Determining Your Battery Type 

CAUTION:  DIFFERENT BATTERY TYPES HAVE 
DIFFERENT CHARGING REQUIREMENTS.  
FAILURE TO PROPERLY IDENTIFY YOUR 
BATTERY TYPE, AND SET THE CHARGER 
ACCORDINGLY WILL RESULT IN BATTERY 
DAMAGE, AND VOID THE WARRANTEE. 

Your machine may have been ordered with batteries 
installed at the NSS factory.  The standard battery 
type, normally supplied by NSS, is the Flooded (wet) 
cell lead acid battery.  Gel and AGM sealed batteries 
may also be available at customer request. 

Flooded (wet) batteries can be easily identified by the 
removable cell caps.  Removing the caps allows 
inspection of the liquid electrolyte (sulfuric acid) level 
in each cell. 

AGM (Absorbed Glass Mat) batteries are sealed, 
maintenance free batteries.  They do not have cell 

caps intended for removal.  Look for 

“AGM” 

printed 

on the tops or sides of the batteries.   

Gel (gelled electrolyte) batteries are also sealed, 
maintenance free batteries. They do not have cell 
caps intended for removal.  Look for 

“GEL” 

printed

on 

the tops or sides of the batteries. 

Battery Charger Indicator LED’s 

Your battery charger is equipped with LEDs that 
indicate the following: 



Battery Type Setting.  Either of these two 
LEDs will be illuminated, anytime the charger 
is plugged in, to signal which type(s) of 
batteries the charger is configured to charge.  
The two options available are: 

o

  Wet / AGM:  When this LED is 

illuminated, the charger is configured 
to charge either flooded (wet), or AGM 
batteries. 

o

  Gel Cell.  When this LED is illuminated, 

the charger is configured to charge 
Gel batteries ONLY.  

EXCEPTION:  

Trojan AGMs are to be charged 
with the Gel setting.



State of Charge Indicators.  Four additional 
LEDs provide information about the charge 
level of the batteries during charging. 

o

  30%, 60%, 90% and 100%. 


