Controls are grouped in a central area at the rear of the machine. Bail Handle (A) When the scrubdeck is lowered to the floor, The Bail Handle Enables the brush motor and moves the machine forward once depressed.
Optional Hour Meter Minuteman offers an optional hour meter for the E17/E20. The optional kit replaces the power cord mounting bracket at the rear of the machine with one that contains an hour meter. Kit# K-E1720HM Optional Solution Solenoid Minuteman offers an optional solution solenoid for the E17/E20. The optional solenoid automatically turns off the solution flow when the brush motor is not active.
Circuit Breakers The circuit breaker is located at the bottom of the back panel of the machine.The 4-amp breaker (A) protects the main controls circuit, The 30-amp breaker (B) protects the brush motor circuit, and the 20-amp breaker (C) protects the vacuum motor circuit. A B C MAIN CONTROL BREAKER BRUSH MOTOR BREAKER VACUUM MOTOR BREAKER If any of the functions above are not operating, check if the circuit breaker buttons have tripped. Press to reset.
Rear Squeegee The rear squeegee is the main element of the conduit that transfers the spent solution into the recovery tank. A daily maintenance check of this component is essential to have optimum machine performance. The blade configuration has two usable edges and can be turned inside out to utilize the opposite side of the blade. If streaking occurs it is time to turn the blade to good edge or replace if this has already been done.
Handle Adjustment The E17/E20 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.
Solution Tank Drain Hose / Level Indicator 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. B A 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.
Brush Load / Unload Loading Brush To load the brush, first center the E17/E20 brush deck over the scrub brush. Lower the scrub deck by releasing the deck lift pedal. With the key turned on, pull the bail handle to spin the scrub brush onto the scrubdeck. Momentarily (1 to 2 seconds) turn the key to the “Brush Unload” position. If done correctly the brush should release from the scrub deck and fall to the floor.
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. A B C The float should be cleaned daily by thoroughly rinsing with a hose. Removal of the screened float is not necessary for daily maintenace.
The E17/E20 This machine was designed with total operator comfort and ease of use in mind. All machine components have been designed as a total system to efficiently clean dirty floors. The E17/E20 has two available scrub head types and sizes to fit specific applications. Please contact your Minuteman representative for specific recommendations for the correct scrub head type, size, and brush type and chemical applications.
Machine Operation To Turn on Machine: Turn key to operate position ( I ) To Turn on Vacuum: Lower squeegee into operate position, vacuum motor will turn on automatically. To Turn on Brush Motor: Move brush lift pedal from the “home” (down) position to the operating position (up). Depress the operator bail handle. Brush motor will turn on and assist to propel the machine forward. To Turn on Cleaning Solution: Move solution lever from closed (down) position up to the desired flow position.
After Use When finished scrubbing, lift the scrub deck and turn the solution lever off, water flow will cease. Lift the rear squeegee (the vacuum motor will turn off). Move the machine to a service area for daily maintenance and review items that may need service. Empty the solution tank, by disconnecting the solution tank drain hose from the barb fitting over a drain. Rinse the tank with clean water to prevent any build-up of dried chemicals that could clog the plumbing.
General Machine Troubleshooting Problem Poor water pick-up Poor scrubbing performance Inadequate solution flow or no solution to the floor Machine does not operate Possible Cause Worn or torn squeegee blades Recovery tank full Recovery tank drain hose leak Recovery tank lid gasket leak Debris caught in squeegee Vacuum hose clogged Using too much solution Recovery hose to squeegee or recovery tank disconnected or damaged Worn brushes Wrong brush or cleaning chemical Debris caught on scrub brushes Moving
