HOW TO SWEEP
The sweeper is intended for use on hard relatively at surfaces such as cement, asphalt, and wood block
oors. 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 lter shaker control button for 20 to 30 seconds, the
lter shakers will unload accumulated dust from the lter 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 appropriate PARTS LIST and follow instructions in the 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 appropriate PARTS LIST and follow instructions in the SIDE BROOM
section of this manual.

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 lter 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. Re ll 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 speci c gravity per day over a 30 day period. The battery should be given
a booster charge when a speci c 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 speci c gravity of the individual cells in the batteries. When checking the
speci c 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 signi cant difference of speci c gravity between the cells.
The speci c gravity of the electrolyte should measure 1.285 when fully charged.
Check items for proper operation. If service is required, please contact an authorized

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 oor.
3. Check the width of the pattern on the oor to determine if the main broom requires adjustment.
-A normal sweep pattern left on the oor 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, re-check the sweep pattern to determine if further adjustment is necessary.
-Turn the adjustment knob counter-clockwise 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.

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 (part
number 2-00-05187) that secure the plates to the frame will need to be loosened. The frame can then be
leveled and the bolts retightened.

HOPPER
The hopper houses the debris
compartment, the dust control
lter and the removable
dust baf e. For maximum
performance and service life,
keep the hopper clean and
inspect the seals and aps
daily. Clean the hopper prior
to parking the sweeper at the
end of the day. A clean hopper
will make inspecting the aps
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 lter should be checked daily for damage and cleaned if necessary. A damaged lter must
be replaced to prevent damage to other dust control system components. Inspect the lter for tears in the
lter media or excessive dirt lodged in the pleats. A tear in the lter media will allow dirt to pass through the
lter and can be easily seen as a dirty patch on the top side on the lter. Cleaning the lter is necessary when
the lter 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 “O” position and engage the
parking brake.
2. Raise the hopper lid for access to the lter compartment.
3. Turn the latch, lift the lter frame and remove the lter.
4. Inspect the panel lter for tears and clean or replace if necessary.
5. Reinstall the lter, lower the lter frame and engage the lter latch.
6. Close the hopper cover.
TO CLEAN THE DUST CONTROL FILTER
Clean the dust control lter when the shaker fails to adequately clear the lter. The lter can be cleaned with
compressed air not to exceed 100psi.
To clean the lter with compressed air, apply the compressed air to the top of the panel to back ush the
lodged dirt from the lter pleats. Be careful to not damage the lter media while cleaning. The lter can
be cleaned with a solution of soap and water. If this cleaning method is used do not use the lter until it is
completely dried.

DUST FLAPS
The dust aps 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 aps are used on the wheel well, broom chamber, and broom door. Inspect the aps daily and
replace any ap that shows signs of wear or deterioration. All aps should be replaced when worn or
damaged to the point that they can no longer perform their normal function. The adjustable aps have slotted
mounting holes to facilitate adjustment.
TO ADJUST THE DUST FLAPS
Adjust the aps so there is a 1/8” to 1/16” Gap between the oor and the bottom edge of the aps. The rear
ap adjustment is 1/16” (16 cm.) above the oor.
1. Park Sweeper on a smooth level surface and engage the Parking Brake.
2. Loosen the Flap retaining screws and adjust the ap to clear the oor and leave a 1/16” to 1/8” Gap.
3. Tighten Flap retaining screws while holding ap in position.
4. Drive sweeper on a smooth surface and recheck the aps for proper oor clearance.
