Frequently Asked Questions - E30 Minuteman

How do I start the Minuteman E30 floor cleaner?

Turn the key switch to the ON position, then press the emergency stop button to release it (pull out). Use the throttle control to engage drive and adjust speed.

What type of cleaning solution should I use?

Use a non-foaming, neutral pH floor cleaner recommended for automatic scrubbers. Avoid harsh chemicals that may damage components.

How do I empty the recovery tank?

Turn off the machine, remove the recovery tank drain hose from its holder, and direct it to a floor drain. Open the drain valve to empty.

How often should I charge the batteries?

Charge the batteries after each use or when the battery discharge indicator shows low. Avoid deep discharge; charge for 8-12 hours.

How do I replace the brushes?

Turn off the machine and disconnect the batteries. Lift the brush deck, remove the brush retaining pins, and slide out the old brushes. Install new ones and secure with pins.

Why is the machine leaving streaks on the floor?

Check the squeegee blades for wear or damage. Ensure the solution flow is not too high and the brushes are clean. Adjust brush pressure if needed.

What should I do if the vacuum motor stops working?

Check the recovery tank float valve—it may have shut off the vacuum to prevent overflow. Empty the tank and restart. If problem persists, inspect the vacuum motor and fuses.

How do I clean the squeegee?

Remove the squeegee assembly by loosening the wing nuts. Use a damp cloth to wipe the blades and check for nicks. Reinstall and adjust the blade tension.

Can I use the E30 on carpet?

No, the E30 is designed for hard floors (tile, concrete, vinyl). Using it on carpet may damage the carpet and the machine.

In case it is intended to change the type of battery the charger has to be adjusted only by Minuteman contract workshops.

NOTICE

Charge the batteries properly before starting the machine for the first time. Minuteman cannot be held liable for battery damage resulting from failure to initially charge batteries.

Provide for sufficient ventilation of areas where batteries are charged. – Explosion hazard!

4 Suction hose
5 Fastening device
6 Washers for height adjustment

5.9.1 Cleaning the Squeegee

Check the squeegee (Fig. 12/1) daily and clean as necessary.

5.9.2 Change the Squeegee Blades

Check the inner and outer squeegee blades on the squeegee (Fig. 12/1) weekly for signs of wear. The squeegee blades can be used fourfold by turning them.

1. Lift the squeegee up.
2. remove the suction hose, loosen the two star-shaped knobs and remove the squeegee.
3. Unlock the fastening device (Fig. 12/5) and remove the outer squeegee blade. Turn the squeegee blade or install a new one. Change the inner squeegee blade in the same way.

Fig.12

Maintenance and Care

5.9.3 Adjusting the Blades Angle Adjustment

The angle adjustment is the decisive factor in ensuring that the squeegee blades on the squeegee lie evenly on the floor.

1. Park the machine on a level surface and lower the squeegee.
2. Loosen the counternut on the adjusting screw (Fig. 12/3) and adjust the squeegee using the adjusting screw so that the ends of the squeegee blades have contact with the floor. Figure A

Turn the adjusting screw counterclockwise: The clearance between squeegee blade and floor is reduced in the center.

Figure B

Turn the screw clockwise: The clearance between squeegee blade and floor is increased in the center.

1. Switch the machine on and check the suction pattern. When the machine is operating, the entire surface of the squeegee blades (center and outer areas) must be applied as evenly as possible.
2. Tighten the counternut on the adjusting screw at 5 lb ft.

Fig.13

Maintenance and Care

Height Adjustment

The height adjustment is set to 3 mm at the factory. If streaks are produced, despite an optimum angle adjustment, the clearance between the casters and floor must be adjusted by changing the number of washers on the holder.

In cases of very smooth floors, e.g. finished floors, PVC, linoleum, etc. Number of washers = 2. This corresponds to a clearance of approx. 2 mm.

In cases of very uneven floors, e.g. poorly laid tiles (water does not run off) Number of washers = 4. This corresponds to a clearance of approx. 4 mm.

The Squeegee 110 cm (7569) is equipped with two additional rollers which are adjusted at the factory to a distance of 10 mm to the floor by means of spacers.
