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
broom so the tabs on the drive hub align with the slots on the broom.
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
the side broom.
TO CHECK THE SIDE BROOM SWEEP PATTERN
1. Park the machine on a smooth level surface and turn the Side Broom Switch to the “ON” position.
2. Place the Side Broom Lever in the “DOWN” position.
3. Move the Brooms Control Lever to the “ON” position.
4. While staying in place allow the side broom to sweep for a short period of time. (Allow enough time for the side
broom to leave a clean footprint on the floor).
5. Place the Side Broom Lever in the “UP” position.
6. Move the Brooms Control lever to the “OFF” position.
7. Back the sweeper away from the area where the Pattern was left.
8. Turn Key Switch to the “OFF” position and engage parking brake.
9. Leave operator’s compartment and check the pattern to determine the Floor Contact area.
10. Determine if adjustment to the side brooms height is necessary by examining the floor contact are broom should
contact the floor as shown in fig. 34 above.
If the contact area on the floor does not match the diagram, do one of the following:
- Lower the broom adjustment to increase the size of the pattern
- Raise the broom adjustment to decrease the size of the pattern.
TO ADJUST THE SIDE BROOM HEIGHT
Turn the side broom adjustment knob to change the side broom sweep height. Turn the adjustment knob
counterclockwise to INCREASE the sweep pattern width. Turn the adjustment knob clockwise to DECREASE the sweep
pattern width. Recheck for proper sweep pattern after adjustment.
TO CHANGE THE SIDE BROOM
Change the side broom when the bristles become worn to less than 3 inches length.
1. Park Machine on a smooth level surface, turn key switch to “OFF” Position and engage Parking Brake.
2. Place the side broom lever in the “UP” Position.
3. Remove the lock pin that holds the broom flange to the motor shaft.
4. Disassemble the flange from the broom by removing the screws that hold the flange to the broom.
5. Assemble the flange to the replacement Broom and fasten using the hardware removed.
6. Install the replacement broom on the shaft and insert the lockpin.

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.
3. Tighten Flap retaining screws while holding flap in position.
4. Drive sweeper on a smooth surface and recheck the flaps for proper floor clearance.

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)
