TOWING OR PUSHING A DISABLED MACHINE
GENERAL INFORMATION
The machine’s drive propelling pump is manufactured with an
adjustabletowvalve. Thisvalvepreventsdamagetothehydraulic
systemwhen the machine is being towed/pushed short distances
without use of the engine.
To access the valve open the left front door panel and locate the
valve as shown on top front of the propelling pump. Use a pliers
or a 5/16” (8 mm) open end wrench to turn the valve 90 degrees,
this disengages the hydrostatic lock between the motor and
pump.
CAUTION!
The hydraulic propelling pump can be damaged if the ma-
chine is towed with the valve in the normal working position
(A).
Referencetheillustrations belowforthenormal working setting(A)
(vertical) and the free wheeling towing setting (B) (horizontal).
Note: Ifthetowvalveisleftinfreewheeling(B)(horizontal)position
the propelling pump can’t drive the machine FWD or REV. No
damage will result, just re-set valve to the normal working setting
(A)(vertical). NOTE:Towor push machine nofasterthananormal
walking pace (2-3 mph - 3-5 km/h) and for short distances only. If
the machine is to be moved long distances the drive wheel needs
to be raised off the floor and placed on a suitable transport dolly.

FUNCTIONAL OVERVIEW
The 2060 / SR 1800 sweeper has a forward-throw or dustpan designed sweeping system. In a forward throw design the broom is made
to rotate in such a direction that it will sweep the dirt and debris forward into a front-end hopper. The broom is driven by a drive lug
assembly, which is a lug mounted on a hydraulic motor, located on the left side of the broom housing. The right side of the broom is
mounted to an idler hub assembly, which swings out of the way to allow for easy broom removal. The drive and idler assemblies are
connected by a hex arm weldment, this arm is connected through a linkage to the broom lift lever, which raises and lowers the broom.
A side broom is used to sweep debris from edges or curbs into the path of the main broom. A hub mounted to a hydraulic motor drives
the side broom. The motor is mounted on a weldment that will allow for the correct side broom angle adjustment. The side broom is
raised and lowered by a cable that is connected at the side broom lever, runs through three pulleys and is connected at the side broom
weldment. The cable and pulleys are accessible by removing the right side hopper panel.
The main broom and side broom are driven by hydraulic motors. Electrically activated control valves control the hydraulic flow to the
motors. The main broom solenoid (L3) is energized when the main broom switch (S13), a NC switch is not activated. The side broom
solenoid (L4) is energized when the side broom switch (S14), a NC switch is not activated. The main and side broom motors will only
operateif thehopperdump doorinterlockswitch (S12)isclosed. If thehopperdump doorisclosed, orifthe hopperisraised, theinterlock
switch (S12) will open the circuit to S13 and S14, not allowing the solenoids L3 and L4 to energize, and will light up the Dump Door
Indicator Light.
The first accessory gear pump hydraulically drives the two motors. When L3 and L4 are not energized the hydraulic oil will bypass the
motors. The relief valve for the system is located inside the same block as the (L3) main broom solenoid valve. This relief valve is set
to open at 2500 PSI.

MAIN BROOM MAINTENANCE
SincetheMain Broom Motoralwaysturns in thesamedirection,the bristles onthebroom eventually becomecurved,reducingsweeping
performance. Sweeping performance can be improved by removing the broom and turning it around (end-for-end). This procedure,
known as “rotating” the main broom, should be done once every 30 hours of operation.
The main broom should be replaced when the bristles are worn to a length of 2-1/2 inches (6.35 cm). The main broom stop must be
re-adjusted when the broom is replaced.
NOTE: The machine should be stored with the Main Broom in the raised position.
WARNING!
The engine must not be running when performing this procedure.
To Rotate or Replace the Main Broom...
1Turn the Ignition Key Switch (52) OFF.
2Put the Main Broom Raise / Lower (ON / OFF) Lever (53) in the DOWN position.
3Open the Main Broom Access Door (15).
4Remove the large T-Bolt from the side of the broom idler arm. Pivot the idler arm assembly out of the main broom core.
5Pull the main broom out of the broom housing and remove any string or wire wrapped around it. Also inspect the skirts at the front,
back and sides of the broom housing. The skirts should be replaced or adjusted if they are torn or worn to a height of more than
1/4 inch (6.35 mm) off the ground.
6Turn the broom around (end-for-end) and slide it back into the broom housing. Make sure that the lugs on the broom drive hub
(left side) engage the slots in the broom core.
7Swing the idler arm assembly back into the broom core and re-install the T-Bolt that holds the idler arm in place.
8Close and latch the Main Broom Access Door (15).
To Adjust the Main Broom Height...
1Drivethemachinetoanareawithalevelfloorandsetthe
parking brake.
2PulltheMainBroomRaise/Lower(ON/OFF)Lever(53)
back and slide to the left and up to lower and start the
main broom. DO NOT move the machine.
3Letthemainbroomruninplacefor1minute. Thisallows
the broom to polish a “strip” on the floor. After 1 minute,
raise the broom, release the parking brake and move
the machine so that the polished strip is visible.
4Inspect the polished strip on the floor. If the strip is less
than 2 inches (5.08 cm) or more than 3 inches (7.62 cm)
wide, the broom needs to be adjusted.
5SeeFigure1. Toadjust,loosentheHandle(A)andslide
the Stop Bracket (B) up or down to lower or raise the
Main Broom. The farther the Lever (5) travels up in the
slot, the lower the Main Broom will be. Tighten Handle
(A) after adjusting the position of the Stop Bracket (B).
6Repeatsteps1-5untilthepolishedstripis2inches(5.08
cm) wide.
The width of the polished strip should be the same at
both ends of the broom. If the strip is tapered, move the
machine to a different area and repeat steps 1-5. If the
polished strip is still tapered, see broom level adjust-
ment.
