SAFETY SECTION GENERAL SAFETY INSTRUCTIONS AND PRACTICES A careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and observing certain precautions. The first section of this manual includes a list of Safety Messages that, if followed, will help protect the operator and bystanders from injury or death.
Page 6 NiteHawk Sweepers use balanced and matched s ystem components for Curb Brooms, Pick-up heads, and other components. These parts are made and tested to NiteHawk specifications. Non-genuine or “will fit” parts do not consistently meet these specifications. The use of non-genuine or “will fit” parts may reduce Sweeper performance, void Sweeper warranties, and present a safety hazard.

Make sure the Truck’s steering, brakes, wheels good condition and operate properly.
Page 12 Sweep at a speed that allows you to safely operate and control the Sweeper. Safe sweeping speed depends on street condition and the type and amount of debris being collected. Normal ground speed range is between 1 and 3 mph. Slow down for corners, curbs, parked cars, protruding signs and other obstacles.
Page 13 Air enters the fan housing inlet with great force. Caution should be used when the power module is running and the hopper is raised. To avoid being pulled into the fan, do not wear loose clothes, or position yourself, or allow others near the fan housing inlet.
Page 14 Do not allow the Sweeper to come in contact with potentially dangerous and/or hazardous material. Such hazards may include, but are not exclusively limited to, the following: • Fire Hazards- Fuel spills, burning material, • Chemical Hazards- Chemical spills, discarded chemical containers, batteries, •...
Page 15 Allow Sweeper passengers only in situations where their presence is involved in the sweeping operation (operator training, supervision, maintenance inspection). Never carry passengers whose presence distracts from the safe operation or transport of the Sweeper. Passengers must be seated securely and belted in the cab’s passenger seat.
Page 16 Use extreme caution when operating the Sweeper in traffic. To alert motorist of the Sweeper’s presence, the Sweeper is equipped with warning signals. Optional electrical lights, flashers and a warning bar light, strobe, or beacon may be positioned on top of the cab. Use all equipped warning signals to alert motorist and pedestrians of the Sweeper’s presence and relatively slow speed.
Page 17 MAINTENANCE AND SERVICE SAFETY INSTRUCTIONS AND PRACTICES Periodically inspect all moving parts for wear and replace when necessary with authorized service parts. Look for loose fasteners, worn or broken parts, and leaky or loose fittings. Make sure all pins have cotter pins and washers. Serious injury may occur from not maintaining this Sweeper in good working order.
Page 18 Never attempt to repair, lubricate, adjust, clean, remove obstructions or perform any other type of service to any Sweeper component while the Sweeper is in motion or while the Truck engine is running. Completely shut down the sweeping components and the Truck engine and wait for all motion to come to a complete stop before servicing the Sweeper.
Page 19 Water pressure generated by the high pressure water pump has the potential to inflict serious injury. Never attempt to repair a pump or hose or tighten a connection while the system is pressurized. Always shut down the Truck engine and relieve water pressure by activating the system before performing any repairs to the high pressure water system.
Page 20 5. Avoid spilling fuel. Fuel is expensive and can damage plastic and painted surfaces. Clean up spilled fuel immediately. 6. Store fuel and all oils at a site protected from moisture, dirt, and other contaminants. (SWM-18) Never run the Truck engine in a closed building or without adequate ventilation.

Page 29: Overrides
Overrides Curb broom models are equipped with manual override buttons on each valve. In case of an electrical failure, push in the override button located on the ends of the directional valves for the function you wish to operate (see fig. 9 below). Manual overrides are discussed in greater detail on page 44-45.
Page 30: Curb Broom Use And Adjustment
CURB BROOM USE AND ADJUSTMENT The curb broom extends beyond the width of the wheels of the truck on all models. Care should be taken to avoid a collision with the broom and any stationary object. When the broom motor is on the fan speed will decrease slightly. Increase the power setting to 90 or 100 to compensate for the slight diversion of power.
Page 31: Turnbuckle Adjustment
Turnbuckle Adjustment The curb broom turnbuckle adjusts how far the broom extends and retracts. Adjusting how far the broom extends also affects how far the broom retracts and vise versa. To extend the broom further, remove the turnbuckle from the curb broom arm, loosen the two jam nuts and spin the turnbuckle counterclockwise and reinstall.
Page 32: Curb Broom Bristle Block Removal And Installation
Loosen the jam nut on the relief valve and turn the screw counter-clockwise for more speed and clockwise for less. Note that this relief valve also controls the speed at which the broom extends and retracts. Every ¼ turn of the relief valve is equal to 400 psi. Adjusting the relief valve all the way in will void your warranty and could cause damage to your curb broom cylinder.
Page 33: Safety Stand Use
SAFETY STAND USE Never work under a raised hopper without a safety stand or counterbalance. Always remove safety stand before lowering hopper. Failure to do so could cause damage to your cylinder yolk and dump-frame. MAINTAINING THE SWEEPER UNIT Maintenance Schedule Monthly Weekly Maintenance Annual Maintenance...
Page 34: Weekly Maintenance
WEEKLY MAINTENANCE Checking the Hydraulic Fluid Level The hydraulic fluid sight glass is located on the hydraulic reservoir on the passenger side of the unit. The reservoir is full when the fluid level is halfway up the Fluid Sight Glass. Fig.
Page 35: Checking For Leaks
O-ring. The hydraulic system on your NiteHawk Sweeper is vented so it is not uncommon to have a mist of fluid on top of your reservoir; this can sometimes be mistaken for a leak. If a leak does occur call the NiteHawk Service Line at 1-800-448-9364.
Page 36: Checking Pick-Up Head Flaps For Wear
The pick-up head flaps are in need of adjustment when there is a ¼” gap between the pavement and the bottom of the flaps. Your NiteHawk is designed to make flap height adjustment quick and easy. As the flaps wear and a gap appears between the ground and flaps, simply remove one of the skid spacers from each side of the head to allow the flaps to come in contact with the ground.
Page 37 Fig. 19 – Bottom view of Pick-Up Head with Flaps. 3. Note that most of the bolts face toward the back of the truck. Also take note of which bolts face different directions. 4. To prevent confusion, remove, mark and replace only one flap at a time, taking note of which side of the metal strips the flap is on.

MONTHLY MAINTENANCE Main Hydraulic Pump Belt Replacement NH Raptor The main hydraulic pump is attached to the engine of the truck chassis with a series of brackets. The automatic spring loaded tensioner is designed to eliminate the need for periodic belt tensioning.
Page 39: Fresh Air Blower Belt Adjustment
Dust Suppression System (if equipped) The NiteHawk dust suppression system uses 8 Whirljet® hollow cone nozzles that spray a fine mist of water to control the amount of dust the sweeper kicks up during normal operation. The water is pumped from an onboard storage tank to pressurized lines with nozzles located in different areas of the truck.
