OPERATION

2--12
SQUEEGEE SWITCH
The squeegee switch, in conjunction with a
hydraulic flow sensing device, and the scrub
brush lever, controls the position of the rear
squeegee.
To raise the squeegee, flip the switch toggle
forward into the “Squeegee Up” position. This
position cannot be overridden by the hydraulic
flow sensing device.
To lower the squeegee, flip the switch toggle back
into the “Down” position. The squeegee will lower
when the machine starts moving in the forward
direction. When traveling in the reverse direction,
the hydraulic flow sensing device overrides the
squeegee switch and raises the rear squeegee.
This prevents the rear squeegees from being
damaged when traveling in reverse. The
squeegee switch should always be in the “Down”
position when scrubbing.
SCRUB BRUSH LEVER
The scrub brush lever controls the scrub brush
motors. To start the scrub brushes rotating in their
normal direction, pull the lever into the “ON”
position. To stop brush rotation, move the lever
into the “OFF” position.
To start the scrub brushes rotating opposite their
normal direction for double scrubbing, push the
lever into the “REVERSE” position.
SCRUB HEAD POSITION LEVER
The scrub head position lever controls the
position of the scrub head. To raise the scrub
head, pull the lever back into the “RAISE”
position. To stop scrub head movement move the
lever to the “HOLD” position. To lower the scrub
head, push the lever into the “LOWER” position.
SRS LIQUID LOW LEVEL LAMPS
The SRS liquid low level lamps include two
indicating lamps. The cleaning solution lamp lights
when the cleaning solution level is low. The
recycling solution lamp lights when the recycling
solution is low.

SRS CLEANING SOLUTION FLOW KNOB
The SRS cleaning solution flow knob controls
the pumping of cleaning solution into the solution
flow to the floor. The “LOW”, “MED”, and “HI”
levels indicate the rate of cleaning solution flow.
The “LOW” level causes the pump to deliver
one-fourth flow capacity, “MED” level one-half
capacity, and “HI” level full pump capacity of
cleaning solution into the solution flow to the floor.
The “OFF” position shuts off the cleaning solution
flow.
ENGINE CHOKE KNOB -- CONTINENTAL
ENGINES
The engine choke knob is present on gasoline
powered machines. The knob controls the engine
choke. To aid the starting of a cold engine, close
the engine choke by pulling the knob out. After the
engine has warmed up, push the knob in to open
the engine choke, allowing the engine to run
normally at its operating temperature and speed.
Using the choke on a warm engine is not
necessary.
