FILLING THE FUEL TANK
WARNING!
• Always stop the engine before filling the fuel tank.
• Do not smoke while filling the fuel tank.
• Fill the fuel tank in a well-ventilated area.
• Do not fill the fuel tank near sparks or open flame.
• Use only the fuel specified on the fuel tank decal.
MODEL 56459500, 56459502 (GASOLINE ENGINE)
On machines with gasoline engines, the fuel tank is located behind the Right Rear Access Door (19). A decal near the filler neck shows the proper fuel to use
in the machine. Before removing the cap from the tank, wipe all dust and dirt from the cap and from the top of the tank to keep the fuel as clean as possible.
Fill the tank with unleaded 87 octane regular gasoline. Fuel Tank capacity is 12 gallons (38 liters). Wipe up any gas spilled on or near the machine immediately!
MODEL 56459501, 56459503 (PROPANE ENGINE)
On machines with propane engines, the LP tank is located behind the drivers seat , open Right Rear Access Door (19). A decal on the door gives information
about the proper type of tank to be used on the machine.
To install the LP tank remove the tank bracket retainer pin and swing the bracket to the side. Mount a standard 33 pound (14.85 kg) vertical liquid withdraw propane
tank and secure in place with mount bracket and retainer pin.
Connect the fuel hose and open the shutoff valve slowly on the tank. Wear gloves when connecting or disconnecting the fuel hose. Shut the propane tank service
valve OFF when the machine is not in use.

INSTALLING THE SCRUB BRUSHES

Four Scrub Brushes (9) are shipped with the machine. To install them, first raise the brush drive assembly (start the engine, put the Brush Raise-Lever (32) in
the UP position, this will raise the brush mounting plates, then stop the engine). Slide the brushes under the mounting plates and lift them so that the lugs pass
through the slots in the holders. Lock the brushes in place by twisting them so they engage the spring locks.
CAUTION!
Be sure to install the correct brushes for your floor. Nilfisk-Advance will not be held responsible for any damage to floor surfaces.
Scarifier and Grinding Stone kits are available for use on this machine. See your Nilfisk-Advance Distributor for details.
CAUTION!
Use care when using scarifier discs and grinding stones. Nilfisk-Advance will not be held responsible for any damage to floor surfaces
caused by scarifiers or grinding stones.

FILLING THE SOLUTION TANK

Use the correct chemical solution for the job at hand. See your Authorized Nilfisk-Advance Distributor for types of cleaning chemicals and their applications.
Fill the solution tank through the Solution Tank Fill (20) with 55 gallons (208 liters) of clean water and the proper ratio of cleaning chemical. Mix powdered chemicals
with water in a bucket before putting them into the solution tank. Do not fill the tank over 3 inches (7.62 cm) from the top of the tank.
CAUTION!
Cleaning product must be low-sudsing and non-flammable.
ADJUSTING THE SOLUTION FLOW CONTROL VALVES
The two Solution Flow Control Valves (10) are adjustable to allow variable solution flow depending upon the type of floor to be scrubbed. A rough or absorbent
floor surface, such as unfinished cement, will require more solution flow than a smooth or finished floor surface.
To adjust the final solution flow to the Brushes (9) first turn the Key Ignition Switch (45) to the ON position (do not start engine), turn ON the Solution Switch (37)
and push forward the manual Solution Lever (34). Note: Start with the Solution Lever (34) about 1/3-1/2 open. Next press forward on the Drive Pedal (47) to
activate the solution solenoid valve this will start the solution flow. Then adjust the two Solution Flow Control Valves (10) so that cleaning solution is dispensed
evenly on both sides.
Note: Do not use too much solution, as it can affect sweeping effectiveness and pick-up performance.
