SCRUB DECK REMOVAL
(Refer to the “Scrub Head Group” in the parts manual)
1. Lower deck to floor.
2. Disconnect
horn.
3. Remove right skirt.
4. Remove solution line.
5. Disconnect scrub motors from wiring harness.
6. Disconnect actuator barrel from wiring harness.
7. Disconnect actuator wires.
8. Remove actuator from top.
9. Remove two bolts (KEY 16 SCRUB HEAD LIFT
GROUP) to frame.
10. Remove ball joint linkage from front of scrub
deck lift brackets.
11. Jack machine up at front.
12. Slide deck out.
NOTE: When installing the scrub deck it is important
to adjust actuator properly. To provide maximum
clearance for removing/installing brushes without
binding or bottoming out actuator, adjust actuator
such that in raised position there is 1/8” to 1/4” (3mm
to 6mm) clearance from top of scrub head mounts to
bottom of frame.
SCRUB DECK SKIRT AND SIDE SQUEEGEE
(Refer to the “Scrub Head Group” in the parts manual)
The design requires the use of a side squeegee to
direct scrub solution to the main squeegee. The
side squeegee is spring loaded allowing constant
contact with the floor. The deflection of the side
squeegee is controlled at front by a guide that
contacts the floor and at rear by an adjustment knob.
Check the blade and guide for damage and wear.
The
QUICK©
uses a scrub deck skirt to contain the
solution around the scrub brushes. The scrub deck
shirt is self-adjusting by means of its accordion
design. As the brushes wear the skirt assembly will
automatically remain in contact with the floor.
The skirts should be inspected weekly for wear and
damage. Replace the skirts when it becomes
cracked, torn or brittle. The skirt may be removed by
loosening the nut on retaining band at center rear of
scrub head.
SQUEEGEE ASSEMBLY
(Refer to the “Squeegee Group” in the parts manual)
The
QUICK©
steering geometry and the design of
the squeegee assembly allows the squeegee
assembly to follow the track of the scrub of the scrub
head even in hard turns.
The assembly rides on the floor supported by two
wheels which follows changing levels in the floor.
Down pressure and squeegee flair is constant in
relation to the floor. Spring pressure is applied to
squeegee to maintain good contact with the floor.
(Refer to “Adjusting Squeegee”)
Rollers are mounted on each end of the squeegee
assembly to assist in rolling by obstacles.
The squeegee assembly is easily removed from lift
mechanism for service and transport.
