MACHINE PREPARATION
YOUR SWEEPER HAS BEEN SHIPPED COMPLETE, BUT DO NOT ATTEMPT TO OPERATE WITHOUT
READING AND FOLLOWING THESE INSTRUCTIONS.
PREPARATION
1. Uncrate the sweeper and carefully remove packing material.
2. Inspect the battery connections.
3.^ Fill fuel tank with appropriate fuel.
3.* Install motive power batteries. (See Battery Installation Instructions)
4.* Charge batteries using instructions provided with charger. (See Battery Charging Instructions)
WARNING
Risk of personal injury. Never fill fuel tank while engine is running. Always be sure gasoline container and sweeper
are electrically connected prior to pouring fuel. This can easily be done by providing an insulated wire (Perma-
nently attached to the container) with a battery clip attached to the other end.
4.^ Check engine crankcase oil level.
5.^ Check radiator coolant level. Permanent type antifreeze is added at the factory to provide pro tection
to approximately -35° F (-2° C) To retain this level of protection always add 1/2 part water to 1/2
part antifreeze.
6. Check fluid level in hydraulic reservoir which is located in the engine compartment. The hydraulic
reservoir is full when fluid can be seen in the sight glass on the side of the reservoir. To get an accurate
reading the hopper must be in the “DOWN” position. If fluid is required add HYDRAULIC FLUID ONLY.
Use Ford Automatic Transmission Fluid Type “F”.

+
The charging system light illuminates to indicate a charging system fault. When this occurs
the sweeper charging system is not working properly and must be serviced by a qualified
service technician.
DUST CONTROL LIGHT
The Dust Control Light Illuminates to indicate that the dust control filter is clogged. When this
occurs, stop sweeping and use the filter shaker to clear dirt and debris from the filter. After
using the filter shaker continue sweeping.
HOPPER TEMPERATURE LIGHT
When the temperature of the air moving through the dust control system in the hopper ex
ceeds 140° F, an automatic protection feature shuts down the dust control fan and illuminates
the hopper temperature light. When this occurs shut down the sweeper and carefully investi
gate for a possible fire in the hopper. The temperature switch must be manually reset.
DUMP DOOR LIGHT
The dump door light will illuminate when the dump door is not fully open. The light warns the
operator to open the hopper dump door completely before sweeping. Do not sweep when the

HELPFUL HINTS FOR SWEEPING
SIDE AISLES
MAIN AISLE
P4134/0001
P4134 FIGURE 31
HOW TO SWEEP
The sweeper is intended for use on hard relatively flat surfaces such as cement, asphalt, and wood block floors.
Exercise care when maneuvering to keep wheels from dropping off curbs or into pot holes. Do not sweep over
obstructions.
WARNING
Do Not Turn The Steering Wheel Sharply When The Machine Is In Motion. The Sweeper Is Very Responsive To
Movement Of The Steering Wheel. Do Not Make Sudden Turns.
The sweeper is designated for dry sweeping conditions. Wet clay and muddy type material will adhere to
surface of sweeping chamber and hopper. Sweeping performance will degrade if these surfaces are not kept
clean. Large heavy objects such as bricks, large stone, and iron parts should not be swept. Damage to the
main broom or other sweeping system components is possible. String, rope, wire or metal strapping longer than
18 inches should not be swept. These items have a tendency to wrap around moving parts. This can cause
damage or degrade sweeping performance.
SWEEPING GUIDELINES
In actual sweeping, there is no single pattern that can be set forth in this manual. Each installation has its own
conditions, and the operator can readily set his own pattern using these guidelines.
-Pick up large debris before sweeping with machine.
-Use the machine to sweep debris from narrow aisles into main aisle.
-After the machine has made a sweeping run, push the filter shaker control button for 20 to 30 seconds, the filter
shakers will unload accumulated dust from the filter media.
-Sweep debris from main aisle.
-Overlap of broom paths when sweeping. This will eliminate leaving dirty patches.
-Empty hopper when the sweeper leaves debris, while sweeping
-Sweep in straight paths. Do not bump posts. Do not scrape the sides of the machine.
NOTE
Replace main broom when bristles are worn to 1.75 inch (3.5 cm) length. To order replacement brooms, see MAIN
BROOM section of this manual. Replace side broom when bristles fail to sweep debris into the path of the main
broom. To order replacement brooms, see SIDE BROOM section of this manual.
SWEEPING VARIOUS TYPES OF DEBRIS
For heavy sand, dirt, or excessive scattered debris, travel slowly with machine to allow main broom to deliver
best results. Do not expect a completely clean surface on the first pass under these conditions. Sometimes it
is necessary to have extra broom pressure where debris is excessively heavy. See “Main Broom Adjustment” for
information on adjusting broom to a “heavy” sweeping pattern. Material that adheres to the sweeping surface:
This type of wet or sticky material will require more broom pressure.

See the LP instructions in this manual for fueling and service instructions on the LP fuel system and replacement of tanks. Use the pre-start check-list and follow the service chart for daily check points. Read and follow
the safety precautions to assure safe, trouble free operation. Gasoline powered machines use regular grade
unleaded gasoline. Turn the engine off before dispensing fuel into the gasoline powered machine.
WARNING
To prevent possible fire: Never fill fuel tank while engine is running. Always be sure gasoline container and
sweeper are electrically grounded before dispensing gas. This can be done by permanently attaching an insulated
wire with a battery clip on the end to the gasoline container.
WARNING
All internal combustion engines give off harmful fumes and gases while running. Do not start or run the engine in
an enclosed area where the exhaust gases can accumulate. Avoid breathing these gases as they contain poison-
ous carbon monoxide which can endanger your health or life if inhaled steadily for even a few minutes.
WARNING
Check for gas odor before and during starting operations. If gas odor is noticed, stop and check for leaks or
component malfunctions in the fuel system. Check fuel supply hoses for proper connection and signs of abrasion.
Do not start engine when gas odor is present.
WARNING
Keep cigarettes, sparks, and open flame away when working on LP equipment, use caution when inspecting for
gas leaks or when LP tanks are present.
WARNING

MACHINE STORAGE
GASOLINE POWERED MACHINES
Machines to be stored over 30 days should be completely drained of fuel to prevent gum deposits forming on
essential carburetor parts, fuel filter and tank.
The use of a fuel additive, such as STA-BIL, or an equivalent, will minimize the formation of fuel gum deposits
during storage. Such an additive may be added to the gasoline in the fuel tank of the engine.
The following procedure should be used to prepare the machine for storage:
1. All fuel should be removed from the tank. Run the engine until it stops from lack of fuel.
2. While engine is still warm, drain oil from the crankcase. Refill with fresh oil.
3. Remove spark plug, pour approximately 1/2 ounce (15 grams) of engine oil into cylinder and crank slowly
to distribute oil. Replace spark plug.
4. Store in a clean and dry area.
BATTERY POWERED MACHINES
All wet batteries will slowly discharge on standing and will discharge much faster when warm than when cold.
At normal temperature of 80ºF (26ºC) loss of capacity by self-discharge, starting with a fully charged battery,
may amount to an average of .001 specific gravity per day over a 30 day period. The battery should be given a
booster charge when a specific gravity falls .040.
Do not discharge the batteries excessively. Excessive discharge can cause polarity reversal of the individual
cells in the battery which will lead to complete failure of the batteries.
Use a hydrometer to monitor the specific gravity of the individual cells in the batteries. When checking the
specific gravity of the batteries, you should not see a large difference between individual cells. The batteries
may need to be replaced if the battery shows a significant difference of specific gravity between the cells.
The specific gravity of the electrolyte should measure 1.285 when fully charged.

HOPPER
The hopper houses the debris compartment, the dust control filter and the removable dust baffle. For maximum
performance and service life, keep the hopper clean and inspect the seals and flaps daily. Clean the hopper
prior to parking the sweeper at the end of the day. A clean hopper will make inspecting the flaps and seals
much easier and will prevent premature deterioration of hopper components. Do not leave the hopper full of
debris while in storage or when parked for extended periods of time
TO CLEAN HOPPER
Once the hopper has been emptied the insides of the hopper should be rinsed out with water.
TO CHECK HOPPER SEALS
The Hopper seals are important to positive dust control while sweeping. Damaged seals will reduce vacuum
pressure at the broom. Inspect for cuts, tears and proper positioning of the seal material. Replace all seals that
become damaged.
DUST CONTROL FILTER
The dust control filter should be checked daily for damage and cleaned if necessary. A damaged filter must be
replaced to prevent damage to other dust control system components. Inspect the filter for tears in the filter
media or excessive dirt lodged in the pleats. A tear in the filter media will allow dirt to pass through the filter and
can be easily seen as a dirty patch on the top side on the filter. Cleaning the filter is necessary when the filter
shaker fails to adequately clean the pleats.

ENGINE SERVICE
ENGINE AIR INTAKE SERVICE
The importance of maintaining the air filter cannot be overemphasized. Dirt ingested through improperly installed
or serviced, or an inadequate air filter element will wear out the engine more than long hours of operation. Even
a small amount of dirt will wear out a set of piston rings after a few hours of operation. Operating with a clogged
air filter element also causes the fuel mixture to be richer, which can lead to formation of harmful sludge deposits
in the engine. Always cover the air intake when the air filter is removed for servicing. Do not neglect servicing
the air filter. Use only approved replacement parts. Keep all other air intake components such as hoses and
clamps secure and in good condition to prevent ingestion or unfiltered air.
CAUTION
Over maintenance can cause more damage than good. Removing the air filter element more often than is needed
may allow contaminants to enter the engine unnecessarily.

LP GAS SYSTEM
The propane powered Model 6150 fuel system has been modified to operate on LP vapor fuel instead of gas.
The LP fuel system consists of several components not found in a regular gasoline system. The LP fuel system
also contains the associated mounting hardware and plumbing for the LP components. The major LP component are as follows:
-An LP carburetor
-A combination water heated vaporizer and regulator
-A combination LP fuel line filter and lock off valve
-A LP fuel tank, fittings, and relief valves
These components are factory set. Attempts at adjusting these components should only be made by authorized service personnel.
LP LIQUID WITHDRAWAL SYSTEM
The liquid LP fuel flows from the LP tank under its own pressure to the pressure relief valve. This valve is
normally closed, which prevents LP fuel from escaping into the atmosphere. This LP gas is then piped to the LP
fuel filter lock. The fuel filter lock removes unwanted tank scale and deposits from the LP gas. The vaporizer
converts the liquid LP fuel into gaseous LP fuel. This gaseous LP fuel is sent to the primary regulator. The
primary regulator reduces the pressure o f the LP fuel tank and makes the flow more constant. The secondary
regulator reduces LP gas pressure to the level required by the carburetor. From the secondary regulator, the LP
fuel is piped to the carburetor where it is finally metered into the air flow which is sent to the combustion chamber.
LP CHECKLIST
This checklist can be performed quickly and should be done before every use. Be sure to make all necessary
checks as listed on the Maintenance Chart as discussed earlier.
1. Check connectors for leaks.
2. Open the LP storage tank valve.
3. Check the regulator.
4. Start the machine’s engine.

LP GAS VAPORIZER-REGULATOR QUICK CHECK
1. Turn the ignition switch on.
2. Open the radiator cap.
3. Check the coolant for bubbles. If bubbles are present, the vaporizer may have a leaking gasket or developed
a pinhole leak allowing the LP fuel to enter the cooling system.
LP FUEL TANKS
Standard D.O.T. LP fuel tank sizes have 14, 20, 33.5, and 43.5 pond capacities. The liquid volume permitted in
these containers is less than the total volume of the cylinder. This provides for expansion of the LP fuel should
there be a temperature increase above the normal amounts. Excessive heat may cause the fuel to expand too
much causing the safety valve to vent some LP fuel, relieving internal tank pressure.
Each tank is marked showing the type of construction (liquid or vapor), the manufacturer, the date of manufacture, the capacity, the weight, and the date of requalification. D.O.T. fuel tanks must be requalified (checked)
periodically. This requalification must be recorder and maintained for the life of the container.
LP fuel tanks are equipped with the following approved valves and fittings:
-Safety Relief Valve - This is a spring loaded valve that relieves excessive pressures which may develop in
the tank due to unusual conditions.
-Liquid Service Valve - Liquid is withdrawn from the tank through this valve. The LP tank may be filled
through this valve if the tank is not equipped with a filter valve.
-Excessive Flow Valve - This valve is part of the Liquid Service Valve. It is mounted inside the tank and
prevents LP fuel from leaving the LP tank in the event of accidental breakage of external fittings or hoses. It
permits flow in either direction but stops outward flow if that flow becomes excessive.
-Filter Valve - This valve is optional. If this valve is not present , the tank if filled through the service valve
-Liquid Level Gauge - This gauge is optional.
USE AND CARE OF LP TANKS
If an LP tank is damaged or leaking, it should be immediately removed to a designated safe area and the proper
personnel should be notified. Do not attempt to make repairs to the cylinder regardless of its conditions.
Repairs must be made by qualified personnel.
The care a LP tank receives has a direct bearing on how long the tank can be used safely. LP tanks must not
be dropped, dragged, or slid across any surface. To move the LP tank, use a hand truck or roll the tank on its
foot ring while it is being held in position slightly off the vertical.

LP TANK CARE
CHANGING LP TANKS
Refueling machines with LP tanks is an important process. Refueling is accomplished by replacing the empty
LP tank with a full one.
The tank changing operation presents an opportunity for the machine operator to carefully inspect the tank, tank
fittings, the fuel lines and fuel line fittings. If abnormal wear is detected, the operator should report these findings
to the appropriate personnel for immediate action.
TO BEGIN CHANGING THE LP TANK
-Park the machine in a designated safe area and set the parking brake.
-Close the tank valve.
-Remove the quick-disconnect coupling from the tank valve.
-Inspect the machine’s fuel lines and the quick disconnect coupling for damage or abnormal wear.
-Remove the empty tank from the holding service
-Inspect the tank and tank fittings for damage or abnormal wear. Handle the tank carefully. It must not be
dropped or mishandled.
-Store the LP tank in a designated safe area.
-Select a filled LP tank and observe for damage or leaks.
-Carefully install the filled tank in the machine so that the tank centering pin enters the aligning hole in the
tank collar. This assures that the tank is positioned properly and allows for proper operation of the safety
relief valve, liquid level gauge, and service valves.
-Fasten the tank retaining bracket so that the tank is locked into position.
-Reconnect the fuel line to the tank servicing coupling.
-Open the service valve slowly and check for leaks. If a leak is found, close the valve immediately and notify
the appropriate personnel.
-If no leaks are detected, the engine is ready to start. Do not start the engine unless the operator is in
position with the directional control pedal in the neutral position.
STORAGE OF LP FUEL TANKS
Whether the storage is inside or outside, the LP tanks should not be in the vicinity of combustible materials or
high temperature sources such as ovens or furnaces. This may cause the heat to raise the pressure of the fuel
to a point where the safety relief valves would begin operation. Care should be taken to ensure that the cylinders
are stored in such a manner that if the safety relief valves are triggered, the vapor will be relieved rather than any
liquid.
Valves on empty tanks must be closed during storage and transportation. Similar precautions should be taken
in storing machines fitted with LP fuel tanks. They may be stored or serviced inside buildings provided there are
no leaks in the fuel system and the tanks have not been overfilled. If machines are being repaired inside a
building, the shut-off valve on the tanks must be closed except when the engine must be on during servicing.
