Shift into a lower gear before starting up or down a hill. – Avoid sudden stops and starts. Do not go from reverse to forward or forward to reverse without coming to a complete stop. – Do not attempt sharp turns or abrupt maneuvers or other unsafe driving actions that may cause a loss of control.
When applying sand, refer to the Sand Application Rate (page 15) for additional information. wheel goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard. • Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine. • Avoid starting, stopping, or turning the machine on slopes.
Operating Tips • The topdresser material application system is • g012651 Figure 12 1. Gate edge Preparing for Cold Weather Operation • Although limited by the traction of the drive tires, you may use the machine in cold weather. With certain limitations, you may use the machine to apply a salt/sand mixture on pavement for ice control. The PVC conveyor belt material becomes very stiff in cold weather and requires more power to operate belt.
inclines, or grades whenever possible. Do not drive across the face of a slope if possible. There is a risk of overturning the machine, which can result in serious injury or death. • WARNING Tipping or rolling the tow vehicle on a hill will cause serious injury. – If engine stalls or you lose headway on a hill, never attempt to turn tow vehicle around. – Always back straight down a hill in reverse gear. – Do not back down in neutral or with the clutch depressed, using only the brakes.
After Operation After Operation Safety • Park the machine on a firm, level surface; engage the parking brake; shut off the engine; remove the key; and wait for all movement to stop before leaving the machine. • Avoid soft ground because the jack leg could sink and cause the machine to tip over. • Do not disconnect the machine from the tow vehicle on hills, or without engaging the optional jack. • When disconnecting the machine, always chock the wheels to prevent movement.
Maintenance • Ensure that the machine is in safe operating condition by keeping nuts, bolts, and screws tight. If possible, do not perform maintenance while the engine is running. Keep away from moving parts. Do not check or adjust the chain tension when the tow vehicle engine is running. Carefully release pressure from components with stored energy. Support the machine with blocks or jack stands when working beneath it. After maintaining or adjusting the machine, ensure that all guards are installed.
5. Lubrication When working on the wheels, pivot them up or down to expose wheel bolts. Important: If you remove the wheels and installed them, torque wheel bolts as specified in Torqueing the Wheel Bolts (page 21). Incorrect bolt torque could result in failure or loss of the wheel. Grease Specification No. 2 Lithium based grease Greasing the Bearings and Bushings Service Interval: Every 200 hours/Yearly (whichever comes first) 1. Perform the steps in Preparing for Maintenance (page 19). 2.
Drive System Maintenance Checking the Tire Air Pressure Service Interval: Before each use or daily 1. Perform the steps in Preparing for Maintenance (page 19). 2. Check the tire air pressure. g012653 Figure 15 You should measure 138 to 207 kPa (20 to 30 psi) air pressure. Note: We do not recommend lubricating the drive chains unless they become stiff from rust. If the chain rusts, lightly lubricate it with a dry-type lubricant.
3. Rotate motor sprocket assembly (Figure 16) until the wheel-drive chain deflects 3.2 mm (1/8 inch). Note: Access to chain is through cutout in lower side of axle cradle. Important: Do not over tension the chain or it will wear prematurely. Do not under-tension the chain or it will cause sprocket wear. 4. Tighten mounting bolts. Note: We do not recommend lubricating the drive chains unless they become stiff from rust. If the chain rusts, lightly lubricate it with a dry-type lubricant.
Belt Maintenance Tensioning the Conveyor Belt When conveyor belt is adjusted properly, the compressed length of each compression spring should be 4-7/16 inches (112 mm). Adjust conveyor belt as follows: g012663 Figure 20 1. Belt-roller shafts 1. Empty the hopper. 2. Perform the steps in Preparing for Maintenance (page 19). 3. Loosen rear jam nut (Figure 19). 2. 35-1/4 inches (895 mm) Replacing the Conveyor Belt Preparing to Machine 1. Empty the hopper. 2.

Hydraulic System Maintenance Hydraulic System Safety • Seek immediate medical attention if fluid is injected into skin. Injected fluid must be surgically removed within a few hours by a doctor. • Ensure that all hydraulic-fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system. • Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.
4. The proper hydraulic fluids must be specified for mobile machinery (as opposed to industrial plant usage), multiweight-type, with ZnDTP or ZDDP antiwear additive package (not an ashless-type fluid). If level is low, add the specified fluid to raise level. Changing the Hydraulic Fluid Important: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 20 ml (2/3 fl oz) bottles.
Brush Maintenance Important: Do not overfill the reservoir with hydraulic fluid. 8. Install reservoir cap (Figure 35). Checking the Brush for Position and Wear Replacing the Hydraulic Filter Service Interval: Every 40 hours Brush must make enough contact with conveyor belt to disperse top-dressing material but not restrict the rotation of the brush. A piece of stiff paper can be inserted between the conveyor belt and the brush to check the adjustment. .
Cleaning Thoroughly clean the machine, especially inside the hopper. Clean the hopper and conveyor belt area free of any sand particles. g012658 Figure 38 1. Brush motor 3. Slide brush into position at right side, and snug the nuts. 4. Slide brush into position at left side, and snug the nuts. 5. Insert a piece of stiff paper between the brush and the conveyor belt. The brush must be the same height from side to side. 6. If the brush position is correct, tighten nuts.
Storage • Park the machine on a hard, level surface; engage the parking brake; shut off the engine; remove the key; and wait for all movement to stop before leaving the machine. • When the optional jack is installed, rotate it from the horizontal (traveling) position, to the vertical position. • Thoroughly clean the topdresser, especially inside the hopper. The hopper and conveyor belt area should be free of any remaining sand particles. • Tighten all fasteners.
Troubleshooting Problem Difficulty in connecting or disconnecting control wires Topdresser is hard to pull with traction unit Hydraulic leaks Belt and/or brush does not function Possible Cause 1. The traction unit has the wrong connector. 1. Purchase an additional harness from your authorized Toro distributor. 2. The on/off connections are switched with brake wiring. 2. Correct connections. 1. The wheel motors/pumps are not turning. 1. The hydraulic plumbing is reversed. 2.
