SERVICE INSTRUCTIONS
SWEEPING SYSTEM SERVICE
MAIN BROOM
To prevent the broom from “setting” in one direction and to provide the maximum life of the broom it is recommended
that the broom be turned end for end periodically.
TO CHECK THE MAIN BROOM SWEEP PATTERN
Check the main broom sweep pattern after changing the broom or when poor sweeping performance is encountered
while sweeping.
1. While the machine is not moving, lower the main broom to the “SWEEP” position and let machine sweep in one spot
for a short period of time.
2. Before moving machine, raise main broom lever to the “UP” position and move the sweeper forward enough to see
the pattern left by the main broom bristles on the floor.
3. Check the width of the pattern on the floor to determine if the main broom requires adjustment.
- A normal sweep pattern left on the floor will be between 1 and 2 inches wide.
- A pattern that is more than 2 inches wide indicates the broom linkage needs to be adjusted “UP”
- A pattern that is less than 1 inch wide indicates the broom linkage needs to be adjusted “DOWN”
TO ADJUST THE MAIN BROOM HEIGHT
When changing the sweep height adjustment it is recommended that the bolt be adjusted 1 turn at a time. After
adjustment, recheck the sweep pattern to determine if further adjustment is necessary.
- Turn the adjustment knob counterclockwise to INCREASE the sweep pattern width.
- Turn the adjustment knob clockwise to DECREASE the sweep pattern width.
TO REPLACE THE MAIN BROOM
The Main Broom should be replaced when the bristles become worn to less than 2”. The main broom is held in place by
the right side broom door. This feature provides for easy removal and installation of the main broom without the need for
special tools or equipment. Follow the instructions below for main broom removal & replacement.
1. Park sweeper on a smooth level surface, engage parking brake, turn key switch “OFF”, place the main broom lever
in the “SWEEP” position.
2. Lift the door latch to open the right side broom door.
3. Swing the broom drive idler hub out to clear the main broom.
4. Remove the broom from the broom compartment.
5. Install the replacement broom. Pay special attention to the slots on the broom, it may be necessary to rotate the

6. Swing the idler hub to engage the main broom and close the access door. Check the door latch for proper
engagement when closed.
7. Check the Main Broom sweep pattern and adjust as necessary.
MAIN BROOM LEVEL ADJUSTMENT
The main broom level is factory set and should not need adjustment. If the level becomes out of adjustment and the
broom bristle contact pattern is not an even 2” to 3” wide, the broom arm lift frame will need to be adjusted. The frame
is supported by two plates located inside the broom doors. The carriage bolts that secure the plates to the frame will
need to be loosened. The frame can then be leveled and the bolts tightened.

FORM NO. 56043109 - MPV-60 - 7
SIDE BROOM
The Side Broom sweeping angle is not adjustable however the height of the side brooms can be adjusted to
compensate for wear as the broom becomes worn from use. Always check and adjust the sweep pattern after changing

HOPPER
The hopper houses the debris compartment, the dust control filter and the vibrating arm. 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 FLAPS
The dust flaps are very important to sweeping and dust control and are susceptible to damage and should be inspected
daily and maintained in good condition.
TO CHECK THE DUST FLAPS
The Dust Flaps are used on the Wheel Well, Broom Chamber and Broom Door. Inspect the Flaps daily and replace any
flap that shows signs of wear or deterioration. All flaps should be replaced when worn or damaged to the point that they
can no longer perform their normal function. The adjustable Flaps have slotted mounting holes to facilitate adjustment.
TO ADJUST THE DUST FLAPS
Adjust the flaps so there is a 1/8” to 1/16” Gap between the floor and the bottom edge of the flaps. The rear flap
adjustment is 1/16” (16 cm.) above the floor.
1. Park Sweeper on a smooth level surface and engage the Parking Brake.
2. Loosen the Flap retaining screws and adjust the flap to clear the floor and leave a 1/16” to 1/8” Gap.

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 of the filter is necessary when the filter shaker fails to adequately clean the
pleats.
TO CHECK THE DUST CONTROL FILTER
1. Park the sweeper on a smooth level surface, Turn the key switch to the “OFF” position and engage the Parking
Brake.
2. Raise the hopper lid for access to the filter compartment.
3. Turn the filter latch, lift the filter frame and remove the filter.
4. Inspect the panel filter for tears and clean or replace if necessary.
5. Reinstall the filter, lower the filter frame and engage the filter latch.
6. Close the hopper cover and lock the hopper cover latch.
TO CLEAN THE DUST CONTROL FILTER
Clean the dust control filter when the shaker fails to adequately clear the filter. The filter can be cleaned with
compressed air not to exceed 100 psi.
To clean the filter with compressed air, apply the compressed air to the top side of the panel to flush out the lodged dirt
from the filter pleats. Be careful to not damage the filter media while cleaning.
The filter can be cleaned with a solution of soap and water. If this cleaning method is used do not use the filter until it
has completely dried.
TO CHANGE THE DUST CONTROL FILTER
Change the filter panel when damage is evident.
1. Park the sweeper on a smooth level surface, Turn the key switch to the “OFF” position and engage the Parking
Brake.
2. Open the hopper cover latch and raise the cover to gain access to the filter compartment.
3. Turn the latch on the hinged frame counterclockwise and lift the frame.
4. Remove the filter panel.
5. Install replacement filter, lower the hinged frame and engage the latch.
6. Lower the hopper cover and lock the cover latch.
TO CHECK THE VIBRATION ARM
1. Inspect the arm daily to assure it is located directly over the bolt.
2. Inspect the arm to assure there is between 1/32” to 1/16” clearance between the bolt and the arm.
3. Inspect the gland nut to assure that it moves up and down with some drag, this will assure no leakage.
(Silicone on the nut may be necessary to prevent loosening while vibrating)

LP COMPONENTS
LP FUEL SYSTEM
The LP fuel system consists of several components not found on the gasoline system. The LP fuel system also contains
the associated mounting hardware and plumbing for the LP components. The major LP components are as follows (these
components are factory set, adjustments to these components should only be made by authorized service personnel):
1. Throttle plate & mixer
2. Combination water-heated vaporizer & regulator
3. Megajector
4. LP fuel tank, valves & fittings

LP VAPOR WITHDRAWAL SYSTEM
The liquid fuel flows from the tank under its own pressure to the pressure relief valve. This valve is normally closed,
which prevents fuel from escaping into the atmosphere. When the engine is running, LP then flows through the open
fuel lock (lock automatically closes when engine is shut down) and into the vaporizer/regulator where it is converted to
a gaseous state. (The regulator reduces the tank pressure and makes the flow more constant.) As the vaporized LP
moves through the Megajector, the Megajector meters the amount of LP necessary to be piped into the mixer where it is
then introduced into the air flow and 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 connections for leaks.
2. Open the LP storage tank valve.
3. Start the machine’s engine.
LP 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 pounds 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 be
temperature increase above the normal amounts. Excessive heat may cause the fuel to expand too much causing the
safety relief 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 re-qualification. D.O.T. fuel tanks must be re-qualified (checked) periodically. This
re-qualification must be recorded 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 filler 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.
Filler 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 of an 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 a 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 device.
- 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 shutoff valve on the tanks must be closed except when the engine must be on during
servicing.
