For greater heat dissipation, less noise, and lower cost of maintenance, the engine shall have individual replaceable wet sleeve cylinder liners. The engine shall be protected by a dual safety element dry type air cleaner with restriction indicator that alerts operators that it is time to service the the air cleaner. Engine shall be filled with 50/50 mixture anti-freeze/water mixture for cold weather operation or storage. The engine shall drive the blower fan by a heavy duty five groove power belt, without the use of a step-up auxiliary gearbox. The power belt provides ease of maintenance and is more cost effective than a step up type gear box. ---PAGE BREAK--- Page 13 of 21 page 2 of sweeper specifications SWEEPER ENGINE – cont. Meets Specs. YES NO To minimize noise and vibration, the entire joined engine, coupling and Fan assembly shall be isolation mounted on the auxiliary frame. The engine shall be enclosed and surrounded by the front part of the sweeper body, by two fiberglass access doors. One at the right-hand side and one at left-hand side of the sweeper body. These doors will provide access to the serviceable items without tilting the body. A fluid coupler shall be installed between the auxiliary engine and the power belt drive, which allows for smooth starting and stopping of the engine. The coupler prevents the momentum of the fan system from driving the engine when the engine is turned off. A Turbo II Engine Precleaner shall be installed on air intake prior to filter.

Replacement of the blower housing must not require any cutting and welding of the housing and or hopper. The blower shall be mounted on heavy-duty re-greaseable bearings, capable of being greased from ground level. Greasing of the bearings must be possible without tilting the hopper. Any grease lines from a remote grease fitting shall be at least 5/16 inch ID to allow for a free unrestricted flow of grease to the bearings. ---PAGE BREAK--- Page 14 of 21 page 3 of sweeper specifications Meets Specs. YES NO III. SUCTION NOZZLE AND HOSES The suction nozzle pick-up area shall be a minimum of 174 sq. in. with Suction nozzle width a minimum of 30 inches. The suction hose shall have a quick disconnect coupling, not requiring any tools, at the lower area, near the suction nozzle. This is to allow easy access to both the suction nozzle and suction hose for inspection and cleaning when obstructions occur. The quick disconnect must be accessible without tilting the hopper. The entire suction hose quick disconnect section and hose transition piece into the suction hose gate valves must be of a bolt-on design for easy maintenance and service. All metal components, nozzle, tube, etc. shall be constructed of abrasion resistant steel for longer life in an abrasive environment. Cast aluminum components or components using rubber liners are not acceptable due to shorter service live. The suction hose shall be not less than 11 inches inside diameter allow to allow for larger objects and large quantities of debris to enter the suction hose. The suction hose shall extend a minimum nine inches beyond the wheel track for increased performance closer to the curb and better visibility of the nozzle from the cab. The nozzles shall have a replaceable wear edge for wear due to rubbing if/when the nozzle comes into contact with the curb. An integral automatic “jackknife style” gate valve shall be bolted on the top of the suction hose where the material enters the hopper. The gate valve is automatically activated with the suction nozzle activation and prevents material from dropping back down the nozzle tubes when the vacuum is stopped. The gate valve also prevents material/debris from being dropped into the suction nozzle when the sweeper is traveling. The jackknife style gate valve is of such a design that it cleans itself from debris. It is operated by a heavy-duty air cylinder that activates the gate valve. This cylinder shall be similar to other air cylinders used in the air system of the sweeper for interchangeability of parts and easy service. The suction nozzle shall ride on two heavy-duty caster wheels. These caster wheels shall be of a pivoting design. This allows the nozzle to move sideways, better for staying in the path of debris and following road contours, as well as improving service life. Non-pivoting caster wheels are not allowed as they have a reduced service life. The suction nozzle shall be equipped with an auto shutter controlled by a Switch on the sweeper control consol. This shutter allows easy entry to large Objects and large quantities of leaves. The shutter must be replaceable as a Separate part, rather than replacing the entire suction nozzle. Suction nozzles That pivot in the back creation a shutter opening in the front, or suction Nozzles that have no shutter as part of their design shall not be allowed. ---PAGE BREAK--- Page 15 of 21 page 4 of sweeper specifications SUCTION NOZZLES & HOSES – cont.

The side broom shall be 36 inch in diameter, with hydraulically driven rotation. The side broom shall be pneumatically raise, lowered and suspended by heavy duty pneumatic cylinders that are common with other pneumatic cylinders on the sweeper for ease of service and maintenance. Adjustable down pressure shall be pneumatically controlled by the operator from the cab. The broom hydraulic drive motor shall provide not less than 4500 in/lbs. of torque for digging power. The side broom assembly shall have greaseless pivot pin for ease of maintenance. The side broom assembly shall be supported in the storage position by a Transport hook. The side broom operation shall be controlled from in the cab by simple rocker switches. To prevent exposure to accidental laceration by the bristle tips, side broom shall retract with wire bristle tips unexposed. No exception will be allowed to this safety requirement. V. EXTENSION BROOM The extension broom shall be 54 inches long, 16 inches in diameter, disposable and reversible. The extension broom shall be hydraulically driven (with relief valve), and be pneumatically raised, lowered, and suspended.

The hopper rear door shall be hinged at the top of the door and opened by means of a hydraulic cylinder. The hopper rear door should open at a minimum angle of 90 degrees to be perpendicular to the hopper opening for maximum dumping action. The City of Douglas has evaluated many styles and considers this design to be the most effective for dumping and cleaning. Exceptions to this requirement will not be acceptable. Hydraulic cylinder movement shall be controlled by the use of two hydraulic valve levers on the right-hand side of the hopper. This method is used in order to view the discharging of debris out of the hopper during dumping for maximum safety. For maximum operator safety the rear hopper door shall have an external door prop. No exception to this safety requirement shall be excepted. ---PAGE BREAK--- Page 17 of 21 page 6 of sweeper specifications HOPPER – cont. Meets Specs.
