MAINTENANCE
5. BRAKES
The brake pedal and the parking brake operate the
two self-centering rear axle disc brakes. With the
parking brake set, the brakes should hold machine
from moving with full throttle in either forward or
reverse. This brake check should be performed in
the pre-run check before each days operation. The
disc and calipers should be inspected every 200
hours of operation for cracks and disc wear. The
disc brakes should be adjusted so that the disc pads
are as close to the disc as possible, without causing
brakes to drag.
FOR SAFETY: Before leaving or servicing
machine; Stop on level surface, set parking
brake, turn off machine and remove key.
1. Remove batteries from machine. (Refer to
section on BATTERY REMOVAL).
2. Jack up rear of machine and support on jack
stands. (Refer to section on JACKING
MACHINE).
3. Once machine is secure on jack stands, release
parking brake.
4. Locate the brake adjustment screw on each
brake caliper.
5. Loosen the lock nut and turn the adjusting screw
to adjust each brake so pad just contacts brake
disc. Repeat on opposite side. Adjust both
sides for equal contact. Arms should be in same
position relative to each other.
6. Lower machine and reinstall batteries.
6. TIRES AND WHEELS
Inspect tires for proper inflation, cuts and abrasions.
Tires should be inflated to 60 psi (4 bars) front and
rear (pneumatic tires only).
Check lug nuts for tightness. Lug nuts should be
tightened to 80 foot-pounds (11 kg-meters). Wheels
should be checked for cracked or bent rims.

7. SOLUTION STRAINERS
The solution strainers are located behind each front
wheel of the FlexCat3. The solution strainers protect
the solenoid valve from debris. If there is little or no
solution flow to the ground, check the strainers for
debris. Drain the solution tank and clean the solution
strainers. To remove the strainer, turn the bottom
part of the strainer counterclockwise until the bottom
is separated. Clean out the debris from the wire
mesh and re-assemble. Make sure the O-ring gasket
is in place when re-assembled.
8. FLOAT SWITCH
The float switch is located inside the recovery tank.
The purpose of the float switch is to notify the user
that the recovery tank is full. When the float switch is
activated, the scrub brush motors and solution flow
will stop, the scrub deck will raise, the squeegee will
rise after 60 seconds, and the vacuum motor will
turn off 10 seconds later.
