Depress the center pin in the accessory quick
connect for 60 - 90 seconds (minimum). The pump
will spray air and solution out until all of the air has
been forced from the solution lines. When all of the
air has been expelled you may resume your
cleaning operation.
NOTE: The solution pump will not prime through the
spray bar or an accessory too.
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
At the end of the day empty all liquids from both the
solution and recovery tanks. Rinse both tanks with
clean water to prevent chemical residue build up,
allow to air dry to prevent odors.
The solution tank can be emptied by: spraying the
liquid out through the spray bar, or using the clean-
out hose.
To use the clean-out hose remove the machine's
recovery hose, from the left elbow of the clear
dome. Replace it with one end of the cleanout
hose.
Remove the mesh filter from the front of the
solution tank and place the other end of the clean-
out hose in to the solution tank.
Turn on the vacuum motor and suction all of the
liquid into the recovery tank.
The recovery tank is emptied through a large
rubber hose at the back of the machine. Remove
the plug and drain the liquids according to your
local government regulations.
Rinse the tank clean of all debris. Position the
clear dome offset on the recovery tank to allow for
air-drying and prevent odor build up.
Remove any residue from the screen and float ball
to ensure proper operation. Replace float
assembly in recovery tank.
Store in a dry area.
Store with brush assembly up.
Check the drain hose for damage.
Remove the spray tips (1/4 turn) from the spray bar
and put them in a glass or plastic container with a
solution of 25% vinegar and water overnight to
remove any chemical residue.
Unplug the machine and inspect the brush
assembly (paying special attention to the ends of
the rollers) for buildup of carpet fibers, hair or other
materials.
Remove all debris from the brush. Failure to
remove this material can overload to the circuit
breaker, jam and break the belt, obstruct and
damage the bearings, or burn out the brush drive
motor.
Weekly Maintenance (25 Hours)
Verify all daily and weekly maintenance has been
performed.
Flush clean solution tank and hoses with a mixture
of 8 ounces (250 milliliters) white vinegar to one-
gallon (4 liter) warm water.
Remove and clean the fine mesh filter in the
bottom of the solution tank.
Check the vacuum shoe for any debris or
obstruction such as carpet fibers. Carefully
remove any debris to ensure the best air-flow and
liquid recovery.
Repair or replace any worn or damaged
components as needed.
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, machine component damage
and failure. This procedure should be performed by
an NSS authorized distributor or service center.
Repairs performed by an unauthorized company will
void the machine warranty. If you require assistance
finding an authorized service center, please contact
NSS Enterprises, Inc.
After every 750 hours of operation
Inspect the vacuum motor carbon brushes for
wear. Replace the vacuum motor carbon brushes
when they are 7/16in. (11mm) in length.
Check the belt for wear and tightness.
