   Important: The Workman hydraulic system operates on Dexron III automatic transmission fluid. This fluid provides gear and bearing lubrication as well as fluid for operating the hydraulic system.When the remote hydraulic system quick couplers are connected, hydraulic fluid flows from the machine to the vehicle. If the hydraulic fluid in the machine is not the same or equivalent to the fluid in the vehicle, component damage to the transaxle or hydraulic system may result.Check for fluid compatibility and take appropriate action if the machine is subsequently used in conjunction with any other product using fluids other than Dexron III ATF.

   Warning

   Hydraulic fluid escaping under pressure can penetrate skin and cause injury.

   • 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 pin-hole leaks or nozzles that eject high-pressure hydraulic fluid.

   • Use cardboard or paper to find hydraulic leaks.

   • Safely relieve all pressure in the hydraulic system before performing any work on the hydraulic system.

   Important: Check the hydraulic fluid level after installation of the topdresser. Check the operation of the topdresser, then check the level of the hydraulic fluid again. Operation of a vehicle with low fluid level can damage the pump, remote hydraulics, power steering, and vehicle transaxle. Use Dexron III automatic transmission fluid if additional fluid is needed.

4. Start the vehicle engine and test the rotation of the conveyor and the brush. Place the remote hydraulics lever of the vehicle in the RUN position. The rotation should be as shown in Figure 18. If the rotation is backwards the quick couplers need to be reversed.

   

   Figure 18

   Important: Ensure that the hoses are routed away from any moving, sharp, or hot components.

5. Visually inspect the hydraulic system for leaks, loose fasteners, missing parts, and improperly routed lines. Make all repairs before operating.

The black knobs on the left rear side of the machine are used to adjust and lock the gate into the desired open height position.

1. Loosen the locking knob (Figure 19) enough to allow it to slide freely in the slot.

2. Set the gate knob (Figure 19) into the desired position and tighten the locking knob to secure the adjustment.

Use the rate scale (Figure 19) to determine the desired flow rate. Refer to Sand Application Rate.

A selection of Toro approved attachments and accessories is available for use with the machine to enhance and expand its capabilities. Contact your Authorized Service Dealer or authorized Toro distributor or go to www.Toro.com for a list of all approved attachments and accessories.

To ensure optimum performance and continued safety certification of the machine, use only genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers could be dangerous, and such use could void the product warranty.

The machine has 5 grease fittings that must be lubricated with a No. 2 lithium grease.

The grease fitting locations (Figure 21) and quantities are: Roller shaft bearings (4) and Brush shaft bearing (1).

Important: Lubricate the bearings to maintain a slight leakage between bearings and housings. Too much grease can cause overheating.

Note: We do not recommend lubricating the drive chain unless it becomes stiff because of rust. If the chain rusts, you can lubricate it lightly with a dry-type lubricant.

Figure 21

Check the hydraulic lines and hoses for leaks, kinked lines, loose mounting supports, wear, loose fittings, weather deterioration, and chemical deterioration. Make all necessary repairs before operating.

The brush must make enough contact with conveyor belt to disperse the topdressing material but not restrict the rotation of the brush. You can insert a piece of stiff paper between the conveyor belt and the brush to check the adjustment. The brush must be the same height from side to side. Check the brush adjustment weekly for wear. The bristles of the brush will wear under normal conditions and the distance from the brush to conveyor belt should be maintained to prevent uneven wear of the brush.

Note: If using moist topdressing materials, you may need to adjust the brush so that the bristles will whisk material from between the conveyor belt lugs without severely contacting the smooth portion of the belt.

1. Loosen the nuts securing the bearing housing (Figure 22) to the right side of the machine.

   

   Figure 22

3. Slide the brush into position on the right side. Finger tighten the nuts.

4. Slide the brush into position on the left side. Finger tighten 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 adjustment is correct, tighten the nuts. If not, repeat the procedure.

Adjust the chain tension so that it deflects 3 mm (1/8 inch). Do not overtighten the chain; this will cause chain wear. Do not operate with a loose chain, this will cause sprocket wear.

Important: The fasteners on the covers of this machine are designed to remain on the cover after removal. Loosen all of the fasteners on each cover a few turns so that the cover is loose but still attached, then go back and loosen them until the cover comes free. This will prevent you from accidentally stripping the bolts free of the retainers.

1. Remove the chain cover assembly and spacer (Figure 24).
