Machine Maintenance; Daily Maintenance - NSS WRANGLER 2016 AE Instructions D'origine

 Take the machine to an approved disposal drain and
turn off all switches.
 Pull the flexible rubber drain hose out from behind the
brush motor. Raise the end of the hose above the
level of the recovery tank, loosen and remove the
hose drain plug. Carefully direct the drain hose into
the drain.
 When the recovery tank is empty, replace and tighten
the drain plug. Place the drain hose back behind the
brush motor. Do not obstruct the lift mechanism or
brush motor.
Special Cleaning
This machine may be used to perform special cleaning
jobs other than "normal" scrubbing.
Double scrubbing
 This procedure provides deeper cleaning on heavily
soiled floors. One or more cleaning passes are made
before picking up the chemicals with the squeegee.
This allows dwell time. Best results are achieved by
placing the brush motor in the heavy scrub position.
Caution: The floor surface becomes extremely slippery
in this operation. This machine should be operated only
in slow to medium speed and great care should be
taken when walking on this wet surface.
Stripping:
 This procedure is used to remove moderate build-up
of floor finish from the floor. The most aggressive
pads or brushes are used in this procedure.
 The stripper solution is applied to the floor with a mop
and then double scrubbed as described above.
Stripping solution should not be put into the solution
tank. Clean water from the solution tank is applied to
the floor to keep the chemicals and finish in a "liquid"
condition. The floor surface becomes extremely
slippery in this operation. This machine should be
operated only in slow to medium speed and great
care should be taken when walking on this wet
surface.

MACHINE MAINTENANCE

Routine maintenance is critical to ensure proper
machine operation and cleaning performance. Perform
all maintenance procedures as follows.
Always turn OFF all machine switches before
performing any maintenance.

Daily Maintenance

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 [120
to 175 mL] of defoamer chemical into the recovery
tank before resuming work. Vacuum the defoamer
into the empty recovery tank through the squeegee
vacuum 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 vacuum filter located under
the top metal plate. Every 50 hours.
Pad driver or brush
 Remove pad driver or brush from machine.
 Rinse with clean water to prevent chemical build-
up. Allow to air dry on 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.
 Inspect and clean float screen and small vacuum
filter above float.
 Check solution flow to pad driver/brush head.
Inspect and clean solution filter assembly.
 Flush solution tank and hoses with a mixture of 8
oz [250 mL] white vinegar to 1 gal [4 L] water.
 Repair or replace any worn or damaged
components as needed.
Monthly Maintenance (100 hours)
 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.
