Tennant Sweeper Scrubber M17

Warning: When servicing machine, use cardboard to locate leaking hydraulic fluid under pressure. High pressure fluid escaping from a very small hole can almost be invisible, and can cause serious injuries.

Consult a physician immediately if injury results from escaping hydraulic fluid. Serious infection or reaction can occur if proper medical treatment is not given immediately.

Check hydraulic hoses for wear and damage

Describe any wear or damage found on the hydraulic hoses

Contact a mechanic or supervisor if a leak is discovered.

Battery watering system (option): Check hoses and connections for damage and wear

The optional battery watering system provides a safe and easy way to maintain the proper electrolyte levels in the batteries.

Check the battery watering system hoses and connections for damage or wear after every 100 hours.

FOR SAFETY: Before leaving or servicing machine, stop on level surface, turn off machine, set parking brake, and remove key.

1. Lift the battery compartment cover open and engage the support.

2. Fully charge batteries prior to using the battery watering system. Do not add water to batteries before charging, the electrolyte level will expand and may overfl ow when charging. See CHARGING THE BATTERIES.

3. Connect the battery watering system hose to the water supply source.

NOTE: Water quality is important to maintain the life of the battery. Always use water that meets battery manufacturer requirements.

NOTE: The water supply to the battery water system must always be 7.57 LPM (2 GPM) or more. Use the purger to confi rm the water supply pressure. Refer to manufacturer Operator Manual for additional information.

Deflection is the amount of curl the overall squeegee blade has when the machine moves forward. The best deflection is when the squeegee wipes the floor dry with a minimal amount of deflection.

NOTE: Make sure the squeegee is level before adjusting the deflection. See LEVELING THE REAR SQUEEGEE.

Lower the squeegee and drive the machine several meters (feet) forward and slowly bring the machine to a stop.

FOR SAFETY: Before leaving or servicing machine, stop on level surface, turn off machine, set parking brake, and remove key.

Look at the amount of deflection or “curl” of the squeegee blade. The correct amount of deflection is 12 mm (0.50 in) for scrubbing smooth floors and 15 mm (0.62 in) for rough floors.

Lower the rear bumper door / step.

To adjust the overall squeegee blade deflection, loosen the lock knobs on both sides of the machine.

Raise the side brush assembly and turn off the machine.

FOR SAFETY: Before leaving or servicing machine, stop on level surface, turn off machine, set parking brake, and remove key.

Reach into the center of the brush and remove the cotter pin and washer holding the brush and the retainer to the hub.

Remove the side brush and retainer from under the side brush assembly.

Place the side brush underneath the side brush assembly and align the channel in the retainer with the retainer pin in the side brush hub.

Lift the side brush, retainer, and washer up onto the side brush hub and reinstall the cotter pin into the hub.
