Cleaning the squeegee
Check the squeegee (A) daily and clean as necessary.
- Pull off the suction hose (D).
- Loosen the two star-shaped knobs (B).
- Remove the squeegee (A).
Changing the squeegee blades
Check the inner and outer squeegee blades on the squeegee (A) weekly for signs of wear. The squeegee blades can be reused by turning them (can be turned for 4 total uses). Parts ›
- Pull off the suction hose (D), loosen the two star-shaped knobs (B) and remove the squeegee.
- Unlock the fastening device (E) and remove the outer squeegee blade. Turn the squeegee blade or install a new one, as necessary. Change the inner squeegee blade in the same way.
Adjusting the squeegee blades: angle adjustment
The angle adjustment is the decisive factor in ensuring that the squeegee blades on the squeegee lie evenly on the floor.
- Park the machine on a level surface and lower the squeegee.
- Loosen the lower wing nut (B) on the adjusting screw (A) and adjust the squeegee using the adjusting screw so that the ends of the squeegee blades still have contact with the floor. By turning the adjusting screw (A) counterclockwise, the clearance between squeegee blade and floor is increased in the center (Fig. 1). When turning the adjusting screw (A) clockwise, the clearance between squeegee blade and floor is reduced in the center (Fig. 2).
- Switch the machine on and check the suction pattern. When the machine is in operation, the entire surface of the squeegee blades (center and outer areas) must be applied as evenly as possible.
- Tighten the lower wing nut (B) on the adjusting screw (A) against the metal bracket to lock in the pitch setting.
Adjusting the squeegee blades: height adjustment
If streaks are present, despite an optimum angle adjustment, the clearance between the caster wheels and floor must be adjusted by changing the number of washers underneath the bracket that holds the wheel. The squeegee height is preset at the factory to 0.08 in (2 mm).
In cases of uneven floors, e.g. grouted tile, etc., try the 0.12 in (3 mm) illustration for washer configuration. In cases of very uneven floors, e.g. poorly laid tiles (water does not run off), configure as shown in the 0.16 in (4 mm) illustration.
Keep the extra washers by installing them above the bracket as shown.
The drawing is labeled in millimeters only: 2 mm is 0.08 in, 3 mm is 0.12 in and 4 mm is 0.16 in.
Handle adjustment
The handle was designed with operator comfort in mind. The angle and horizontal position of the handle can be adjusted to suit the needs of the operator.
Angle adjustment
The handle angle can be adjusted without tools by loosening the Angle Adjustment Knob (A) on each side and rotating the handle to the desired position. There are 5 angular positions 11.25° apart for a total of 45° between the minimum and maximum position.
Horizontal adjustment
The horizontal position can be adjusted by removing the 4 Mounting Bolts (B) (2 each side) with a 9/16” socket and sliding the Mounting Plate (P) to one of the 3 available positions. The machine is shipped from the factory in position 1.
Aqua-Saver solution control
In order to consistently conserve water when using Aquastop brushes, the guide will stop the solution control lever at a low rate setting. This setting may be adjusted by loosening the knob, adjusting the lever, and retightening the knob. Slide the knob all the way forward to dispense maximum solution.
Solution tank drain hose
The solution tank may be drained by removing the Solution Tank Drain Hose (A) from the Hose Barb (B) and routing the hose to a floor drain.
Solution level indicator
The Solution Tank Drain Hose also serves as a water level indicator for the solution tank. The amount of water remaining in the solution tank can be seen through the clear drain hose. Level markers molded into the solution tank are positioned at 1/4, 1/2, 3/4, and full levels.
Solution fill filter
The Solution Fill Filter (B) should be cleaned regularly. To remove, simply open the Solution Tank Lid (A) and pull the filter out.
Screened float
If the recovery tank (C) is overfilled or a large amount of foaming is present, the screened float (B) blocks the vacuum intake inside the tank protecting the vacuum motor and internal electronics from water damage. It is essential to keep the float in working order through regular maintenance.
The float should be cleaned daily by thoroughly rinsing with a hose. Removal of the screened float is not necessary for daily maintenance.
At least once a month the screened float should be completely removed, cleaned, and checked for any damage to the seal or metal screen.
Screened float removal
The screened float is positioned between the vacuum manifold (A) and recovery tank (C). The screened float (B) can be accessed by removing the 1.5” bolt (D) and two 1.25” bolts (E) that attach the manifold to the recovery tank using a 7/16” socket.

In-line solution filter assembly
The solution solenoid, which shuts off solution flow when the bail handle is released, is protected from debris by the in-line filter assembly. The filter assembly is located at the rear of the machine on the left hand side, just under the solution tank. It is important to check and clean the screened washer inside the assembly regularly to ensure proper solution flow. To open, unscrew the assembly (Note that the cone of the washer is facing out toward the rear of the machine). Remove washer and rinse, reinsert and screw assembly together, tightening by hand. Overtightening with tools may damage the plastic threads.
