INTRODUCTION
INTRODUCTION
This manual will help you get the most from your American-Lincoln™ - Alto sweeper / scrubber. Read it
thoroughly before operating the machine.
P ARTS AND SERVICE
Repairs, when required, should be performed by your Authorized American-Lincoln™ - Alto Service Center,
who employs factory trained service personnel, and maintains an inventory of American-Lincoln™ - Alto
original replacement parts and accessories.
Call the AMERICAN-LINCOLN / ALTO INDUSTRIAL DEALER named below for repairs or service. Please
specify the Model and Serial Number when discussing your machine.
(Dealer, affi x service sticker here.)
NAMEPLATE
The Model Number and Serial Number of your machine are shown on the Nameplate, located on the wall of
the operator’s compartment. This information is needed when ordering repair parts for the machine. Use the
space below to note the Model Number and Serial Number of your machine for future reference.
MODEL _____________________________________
SERIAL NUMBER _____________________________
Note: Reference the separately supplied engine manufacture’s maintenance and operator manual for more
detailed engine specifi cation and service data.
UN-CRATING
Upon delivery, carefully inspect the shipping crate and the machine for damage. If damage is evident, save all
parts of the shipping crate so that they can be inspected by the trucking company that delivered the machine.
Contact the trucking company immediately to fi le a freight damage claim.

MACHINE OPERATION
FIGURE 1
YOUR 7765/7760 MACHINE HAS BEEN SHIPPED COMPLETE, BUT DO NOT ATTEMPT TO OPERATE WITHOUT FOLLOWING
THESE INSTRUCTIONS.
PREPARING THE MACHINE FOR OPERATION
1. Connect and tighten battery cables.
2. Fill the tank with REGULAR GRADE unleaded gasoline; Diesel fuel if equipped with diesel engine.
WARNING
Never fi ll tank while engine is running. Always be sure fuel container and sweeper are
electrically connected before pouring fuel. This can easily be done by permanently attaching one end of an insulated wire to
the container with battery clip on the opposite end.
3. Check engine crankcase oil level. Although properly lubricated at factory, check before starting engine. No special brand oil is
used. Recommended number of operating hours before the initial oil change is the same as normal. See Maintenance.
4. Check radiator coolant level. Permanent type antifreeze is added at the factory to provide protection to approximately -35° F (37°
C). To retain this protection level, always mix 1 part water to 1 part antifreeze.
5. Check oil level in the hydraulic reservoir located at center of machine beside the engine. Oil fi ll level should be two (2) inches (5
cm.) below fi ller neck assembly. If oil is required, add HYDRAULIC FLUID ONLY, automatic transmission fl uid FORD type “F”. After
the fi rst 50 operating hours, service must be performed on your engine to insure future high performance and trouble-free operation.
See Maintenance.

OPERATIONS OF CONTROLS AND GAUGES
BRUSH ROTATION SWITCH
The Brush Rotation Switch is located on the console to the left of the steering wheel in the “SCRUBBING” section. This switch reverses
the rotation of the scrub brushes. This switch has two positions, “NORMAL” and “REVERSED”. This switch can not be activated unless
the Scrub Brush Lift Switch is in the “LOWER” position. The switch will light when activated.
BRUSH PRESSURE SWITCH
The Brush Pressure Switch is located on the console to the left of the steering wheel in the “SCRUBBING” section. This switch applies
additional downward pressure to the scrub brushes. This switch has two positions, “NORMAL” and “HEAVY”. This switch can not be
activated unless the Scrub Brush Lift Switch is in the “LOWER” position. The switch will light when the switch can be activated.
SQUEEGEE BLADE SWITCH
The Squeegee Blade Switch is located on the console to the left of the steering wheel in the “SCRUBBING” section. This switch in the
position marked “LOWER” will lower the squeegee and activate the squeegee vacuum. This switch in the “RAISE” position will stop the
squeegee vacuum and raise the squeegee. A switch activated by the forward-reverse foot pedal will automatically raise the squeegee if
it is in the lowered position and the machine is in reverse.
HIGH RECOVERY WARNING LIGHT
The High Recovery Warning Light is located on the console to the left of the steering wheel beside the
“SCRUBBING” section. The recovery warning light will illuminate approximately 5 minutes before the recovery tank is full, giving ample
time to complete the scrubbing cycle before the mechanical fl oat shuts off the vacuum to the recovery tank.
LOW SOLUTION WARNING LIGHT
The Low Solution Warning Light is located on the console to the left of the steering wheel beside the “SCRUBBING” section. The Solution
Warning Light will illuminate when the solution tank is empty, marking the end of the
scrubbing cycle.
