Machine Overview
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. This also allows the operator to automatically load the brush when the scrub deck is lowered
over the brush.
Handle Adjustment Knobs
(B) Allows the handle position to be raised or lowered.
Key Switch
(C) Controls the machine’s power (Brush Unload/Off/On) with a key for safety . This switch, when turned counter clock-
wise, operates the auto brush unload when scrubdeck is in the raised position. When it is turned to the ON position,
the machine will operate.
Squeegee Lift Lever
(D) When actuated to the top position, the squeegee is lowered and the vacuum motor turns on. When locked in the
bottom position, the squeegee is raised and the vacumm motor shuts off.
Solution Control Lever
(E) This lever controls the rate at which solution is dispensed. Moving the lever up will increase the amount of solution.
Moving the lever down will decrease the solution rate. Moving the lever all the way down shuts off solution flow.
Battery Gauge
(F) This gauge activates to show power is on when the key switch is on.

Machine Overview
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 that runs when
the brush motor is on.

Machine Overview
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.
Kit# K-E1720S
In-Line Solution Filter Assembly
The optional 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.

Cleaning the Squeegee
Check the squeegee (A) daily and clean as
necessary.
1. Pull off the suction hose (D).
2. loosen the two star-shaped knobs (B).
3. 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 turned 4 times to use
all 4 edges.
1. Pull off the suction hose (D), loosen the two star-
shaped knobs (B) and remove the squeegee.
2. 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.
16
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.
1. Park the machine on a level surface and lower
the squeegee.
2. Loosen the lower wing nut (B) on the adjusting screw (C) 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 (C) counterclockwise, the clearance between squeegee
blade and floor is increased in the center (Fig.
1). When turning the adjusting screw (C) clockwise, the clearance between squeegee blade
and floor is reduced in the center (Fig. 2).
3. Switch the machine on and check the suction
pattern. When the machine is in operation, the
full edge of the squeegee blades (center and
outer areas) must be applied as evenly as possible.
4. Tighten the lower wing nut (B) on the adjusting screw (C) against the metal bracket to lock
in the pitch setting.

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
2mm.
In cases of very uneven floors, e.g. grouted
tile, etc., try 3mm illustration for washer
configuration.
In cases of very uneven floors, e.g. poorly laid
tiles (water does not run off) ,, configure as
shown in 4mm illustration.
Keep the extra washers by
installing them above the bracket
as shown.

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 1 1.25° ap art
for a total of 45° between the minimum and maximum position.

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.
Machine Overview
A
B
The float should be cleaned daily by thoroughly rinsing with a hose.
Removal of the screened float is not necessary for daily maintenace.
At least once a month the screened float should be completely
removed, cleaned, and checked for any damage to the seal or metal
screen.
WARNING: Damage to the machine may occur if operated
without the screened float properly in place.

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.
