MACHINE INSPECTION

 Now that the machine is unpacked remember to
recycle all packing materials.
 Inspect the machine for damage or missing
components. If damage is found, contact the local
freight company to file a freight claim.

MACHINE COMPONENTS

Solution Tank
The solution tank is the lower part of the machine body.
It has a capacity of 30 gallons (114 liters).
 The amount of water in the tank is measured by the
solution gage, which is located in the clear plastic
tube at the right rear corner of the tank. This tube is
also used to empty the tank.
Recovery Tank
The recovery tank is the upper part of the machine
body. It has a capacity of 33 gallons (125 liters).
 A round clear view lid assembly closes off the
recovery tank's opening.
 The recovery tank has a foam sensitive float shut-off
assembly. As the water level rises, the float ball will
rise into the tube and shut off the airflow of the
vacuum. NOTE: The float shut-off assembly does
not shut off the vacuum motor.
Operator Control Panel
The operator control panel is located at the upper rear
area of the machine. This panel has components that
control various machine functions.
 In the middle of the panel are two (2) rubber twist
grips. These grips rotate forward and backward to
control the direction and speed of the machine. The
farther the grips are rotated, the faster the machine
will move. These twist grips have a feature that
returns the machine to the neutral position when the
handles are released.
 The left toggle switch turns on and off the vacuum
motor.
 The red button is the EMERGENCY STOP switch.
Pushing this button removes power from all motors.
The master power switch must be turned off, then
turned back on, to resume machine operation.
 The right toggle switch (or optional key switch) is the
Master Power Switch.
Battery Meter
The battery meter is located on the right side of the
operator control panel and shows the state of charge of
batteries during operation and recharge.
 When the batteries are fully charged, all of the bars
will be lighted.
 Normal working range is from fully charged down to
only red bars lighted.
 Operation can continue into the red zone; however,
66 dB(A)
the controller will turn off the brush and vacuum
motors once battery drops to a minimum level. The
machine can then be driven to a convenient charging
.367 m/s 2
location.
Rear Panel
 The solution control lever is located on the left of the
rear panel. This lever controls the solution valve and
the amount of liquids put on the floor while cleaning.
Pull up on the handle to open the valve. Push down
on the handle to close the valve.
 The top circuit breaker (25 A) is for the drive motor.
 The next circuit breaker (25 A) is for the vacuum
motor.
 The next two circuit breakers (30 A) are for the brush
motors.
 The bottom circuit breaker (25 A) is for the main
power to the controller.
 The right lift arm is used to raise and lower the brush
motor assembly. Brushes automatically turn on when
lowered, and the twist grips are moved.
Battery Compartment Drain Hose
This hose is located on the left side of the machine
inside the rear panel. The hose uses a pinch clamp to
hold the hose closed. This hose collects any spilled
liquids from the battery compartment area.
 Inspect hose for liquid level on a weekly basis.
 Dispose of liquids according to your local and federal
regulations.
Canister / Strainer Assembly
Attached to the valve, under the left side of the solution
tank is a canister strainer. It is designed to stop debris
from entering the solution solenoid.
If the water and chemical stops flowing during
operation:
 Turn off solution control valve on rear panel.
 Remove the canister and screen, and remove all
debris.
 Replace the screen and canister. Check for any liquid
leaks.
Solution Solenoid
Attached to the top of the brush deck is a solenoid valve
designed to stop solution flow when the machine is not
moving. If the water and chemical stops flowing:
 Check canister / strainer assembly for debris.
 Check manual lever.
Sidekick Chemical Dispensing (optional)
 On board chemical dispensing is available either
factory installed, or as a retrofit kit.
 Controls for chemical dispensing are located on the
Operator Control Panel.
