charging, add only enough water to cover the top of 
the internal plates.  After charging, add only enough 
water to bring the level to the bottom of the fill tube. 



Do not 

overfill the battery liquid, this will cause 

electrolyte (acid) spill.  Spilled electrolyte (acid) can 
cause machine damage and personal injury.  Clean 
and dispose of spills immediately. 



Every cell

 of every battery must be checked and 

replenished (if needed) once per week 



See the battery-warning sheet (page 2) for more 
details.

Battery Packages 

The Wrangler 2016 is a 24-volt system and is available 
with two battery packages. 



  Four (4) 6 volt, 235 Amp Hour Batteries – NSS-PCS.  



  Two (2) 12 volt, 145 Amp Hour Batteries - SPE. 

Solution and Recovery Tanks



  The recovery tank is emptied through a large rubber 

hose at the front of the machine.  Remove the plug 
and drain the liquids according to your local and 
federal regulations. 



Every time

 you empty the recovery tank, we 

recommend that you add at least 4 to 6 ounces of 
defoamer chemical into the recovery tank before 
resuming work.  Vacuum the defoamer into the empty 
recovery tank through the squeegee vac hose. 



  At the end of the day empty all liquids from both 

solution and recovery tanks.  Rinse both tanks with 
clean water to prevent chemical residue build-up, 
allow to air - dry to prevent odors. 



  Remove any residue from screen and float ball to 

ensure proper operation.  Replace float assembly in 
recovery tank. 



  Check clear lid for airtight seal. 



  Check the drain hose for damage. 



  Inspect and clean the vac filter located under the top 

metal plate.  Every 50 hours. 

Pad driver or brush



  Remove either pad driver or brush from the machine 

after use. 



  Rinse with clean water to prevent chemical residue 

build-up.  



  Allow to air dry on a peg or upside down on a shelf or 

rack. 



  Inspect for wear or damage. Repair or replace as 

needed. 

Squeegee Assembly 



  Remove squeegee assembly from machine. 



  Rinse with clean water to prevent chemical residue 

build-up.  ***NOTE: prolonged exposure to some wax 
stripper brands may degrade the squeegee material.  
Rinsing after use in a wax floor stripping application is 
highly recommended. 



  Allow to air dry, it can be stored on top of the machine 

for drying. 



  Inspect the squeegee assembly, linkage, and vacuum 

hose, for wear, damage or obstruction. Repair or 
replace as needed. 



  Check for debris from squeegee hose at entrance to 

recovery tank. 

Weekly Maintenance (20 hours) 



  Verify all daily maintenance has been performed. 



  Check battery terminals and cable connections.  

Tighten as needed.  Loose connections are 
dangerous and can cause personal injury and 
machine damage 



  Clean any corrosion from battery terminals and 

cables. 



  Drain all liquids from battery compartment.  Dispose 

of according to local and federal regulations. 



  Check solution flow to pad driver and / or brush.  

Remove, inspect and clean solution filter assembly. 



  Flush solution tank and hoses with a mixture of 

8oz/250 ml white vinegar to 1 gal/4 l water. 



  Repair or replace any worn or damaged components 

as needed. 



  Inspect and clean float screen and small vac filter 

above float. 

****CAUTION****

Inspect and replenish battery water in every cell in 
every battery weekly.  Failure to maintain proper 
electrolyte level in every cell of every battery will cause 
premature battery failure, and void the warrantee. 

Monthly Maintenance (100 Hours) 



  Equalize your batteries 

(Flooded only).

  To equalize 

the batteries, after they have been fully charged, 
unplug the charger (from the wall outlet), and plug it 
back in.  The charger will skip thru the first few 
phases of the charge cycle, and run thru the finish 
phase.  This will balance out all the cells in the 
batteries, and provide maximum battery life.  THIS 
STEP IS ESPECIALLY IMPORTANT IF YOU 
PRACTICE OPPORTUNITY CHARGING. 



  Verify all daily and weekly maintenance has been 

performed. 



  Lube the caster and swivel bearings.  Spray with 

Silicone Lubricant. 



  Inspect all mechanical linkages, pivot points and ball 

joints for freedom of movement.  Use a penetrating 
spray lubricant that is water resistant. 

 Do not

 use 

WD-40 lubricant. 



  Inspect all fasteners (bolts, screws, nuts) at 

mechanical linkages, pivot points and ball joints for 
tightness.  Tighten as needed. 



  Clean polyethylene body components to remove 

chemical and liquid residue and maintain a “like new” 
appearance. 

Mandatory Periodic Maintenance 

It is 

mandatory

 that the following maintenance procedure 

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 warranty.  If you require 
assistance finding an authorized service center, contact 
NSS Enterprises.
