SAFETY INSTRUCTIONS 12. Using the machine demands attention. Failure to operate tow vehicle safely may result in an accident, tipover of tow vehicle and serious injury or death. Drive carefully. To prevent tipping or loss of control: A. Use extreme caution, reduce speed and maintain a safe distance around sand traps, ditches, creeks, ramps, any unfamiliar areas or other hazards. B. Watch for holes or other hidden hazards. C. Use caution when operating tow vehicle on a steep slope.
SAFETY INSTRUCTIONS 16. Be sure machine is in safe operating condition by keeping nuts, bolts and screws tight. the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result. 17. Make sure all hydraulic line connectors are tight, and all hydraulic hoses and lines are in good condition before applying pressure to the system. 19.

LOOSE PARTS NOTE: Use this chart as a checklist to assure all parts have been received. Without these parts, total set-up cannot be completed. DESCRIPTION QTY. Tongue Assembly Lynch Pin Clevis Pin Wire Harness (3 pc.
SPECIAL TOW VEHICLE INSTRUCTIONS Special Instructions for Workman (3000/4000) and other utility tow vehicles (tractors): IMPORTANT: Do Not attempt pulling the Topdresser 2500 when loaded with material, with the standard Workman (3000/4000) hitch. It is only rated to 1500 lbs. and may bend or damage the cross tube axle support or rear spring shackles. Always use the H.D. Drawbar Kit Model 44212 or H.D. Frame Drawbar Model 44213. 1.
SET-UP INSTRUCTIONS INSTALL TONGUE (Fig. 1 & 2) INSTALL WIRE HARNESS (Fig. 4) 1. Install tongue into topdresser receiving tube and secure each end with a clevis pin and (2) lynch pins (Fig. 1). 1. Plug topdresser wire harness into connector on topdresser solenoid valve. 2. Secure appropriate terminals of tow vehicle harness to tow vehicle battery (+ or -). IMPORTANT: Make sure harness is connected to correct terminals on battery. 3.
BEFORE OPERATING CHECK HYDRAULIC SYSTEM FLUID Mobil EAL 224H is available, in 5 gallon containers (Part No. 100-7674) from your local Toro Distributor. If you wish to use an alternate biodegradable and nontoxic hydraulic fluid, first the hydraulic tank, filter, all lines, hoses, motors and pumps must be completely drained to insure that the new oil will fully circulate and coat all components in the hydraulic system, and reduce the chance of gelling or stratifying in certain portions of the circuit.
BEFORE OPERATING CHECK TIRE PRESSURE Mobil EAL224H does not contain hazardous substances reportable under CERCLA. Since all oil spills are reportable, even a spill of this vegetable oil-based product must be reported to the National Response Center (the U.S. Coast Guard). Local environmental agencies should also be consulted to clarify local requirements. The tires are over-inflated for shipping. Therefore, release some of the air to reduce the pressure. Correct air pressure is 20-30 psi.
CONTROLS GATE METERING CONTROL HAND CONTROL SWITCH The knob and handle on left rear side of machine are used to adjust and lock the gate into the desired open height position. Activating hand control switch starts and stops the flow of material from topdresser. 1. Loosen the adjusting handle enough to allow knob to slide freely in slot. 1 2. Set the gate into the desired position and tighten the handle to lock into position. 2 RATE SCALE Use rate scale to determine desired flow rate.
OPERATING INSTRUCTIONS GENERAL inclines or grades whenever possible. DO NOT DRIVE across the face if at all possible. There is a risk of upsetting the vehicle, which can result in serious injury or death. 1. The Top Dresser 2500 is ground driven, so it will need to be towed in order to check out operation of belt and brush. Factory checks are performed on a powered roller drum. WARNING 2. Top dressing works best at 2 to 8 miles per hour (mph).
OPERATING INSTRUCTIONS 14. Before servicing or making any adjustments to the top dresser: CAUTION A. Stop the tow vehicle and set the parking brake. The interlock switches are for the operator's protection, so do not bypass them. Check op eration of the switches daily to assure interlock system is operating on the Workman. If a switch is malfunctioning replace it before oper ating. Regardless whether switches are oper ating properly or not, replace them every two years to assure maximum safety.
OPERATING INSTRUCTIONS DANGER As a general rule, position the weight of the load evenly from front to rear and evenly from side to side. Transporting or topdressing with a full load can cause shifting of the sand. This shifting hap pens most often while turning, going up or down hills, suddenly changing speeds or while driving over rough surfaces. Shifting loads can lead to tipovers. Use caution when transport ing or topdressing with a full load.
LUBRICATION GREASING BEARINGS The Topdresser 2500 has 13 grease fittings that must be lubricated with a No. 2 Lithium based grease. Lubricate annually or after every 200 hours of operation. The grease fitting locations and quantities are: Roller shaft bearings (4) (Fig. 9), Brush shaft bearing (1) (Fig. 9), Pivot bearings (4) (Fig. 10) and Wheel bearings (4) (Fig. 10). (2) (2) IMPORTANT: Lubricate the bearings to maintain a slight leakage between bearings and housings.
MAINTENANCE JACKING TOPDRESSER 3. Fill reservoir with approximately 2.5 gallons (9.5 l) of hydraulic fluid. Refer to Checking Hydraulic Fluid. 1. The jacking points on the topdresser are the skids. IMPORTANT: Use only hydraulic fluids specified. Other fluids could cause system damage. 2. Any load material must be removed from hopper before working under raised topdresser. 3. Do not work under topdresser without jack stands supporting it. 4. Check level of fluid and add enough to raise to proper level.
MAINTENANCE WARNING Keep body and hands away from pin hole leaks or nozzles that eject high pressure hydraulic fluid. Use cardboard or paper to find hydraulic leaks. Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid acci dentally injected into the skin must be surgical ly removed within a few hours by a doctor famil iar with this form of injury or gangrene may re sult. 1 Figure 15 BRUSH ADJUSTMENT 1.

Pivot hopper rearward and lean against wall, ladder, etc. Do no allow hopper to rest against rear of machine as damage may result to brash or hydraulic couplers (Fig. 26). 1. Chain cover 2. Remove master link from chain and remove chain from small sprocket (Fig. 23).
MAINTENANCE HYDRAULIC SYSTEM DIAGNOSTICS Flow Rates and Performance Checks - Since the Top Dresser 2500 uses ground driven hydraulics, it is necessary to tow the unit to do these performance tests. Rather than using a flow meter to measure hydraulic circuit flow, an approximation can be determined by measuring the brush speed with a rotating contact RPM indicator. See table for flow rate values. 2 HYDRAULIC FLOW RATES AND SPEED TABLE 2 1 Figure 28 1. Lifting rod 2. Slider bed mounting capscrews 8.
MAINTENANCE Bleeding and Priming of Hydraulic System Bleed/drain lines are provided for the drive pumps and belt motor. This helps purge the system of air, hot oil and to circulate clean oil into the hydraulic drive loops. An auto-fill line runs from the reservoir to a special port at the control module with a low resistance check valve.
TROUBLE SHOOTING A. Difficulty in connecting or disconnecting control wires: Wrong connector on tow vehicle. An additional harness may be acquired from your distributor. On/off connections switched with brake wiring. B. Topdresser hard to pull with tow vehicle: Wheel motors (pumps) not turning. Plumbing reversed. Brake solenoid activated (check wiring). Hydraulic oil hot. C. Hydraulic leaks: Fittings loose. Oil filter loose. Fitting missing o-ring. Reservoir over filled. D.
