Lubrication
Lubricating the Machine
-
Use an all-purpose automotive grease.
-
Lubricate regularly, after 25 hours of normal operation.
-
Lubricate daily when operating in extremely dusty and dirty conditions.
-
Lubricate all bearings, bushings, and chains.
Several grease fittings are located on the machine and the tow-behind chassis (Figure 52, Figure 53 and Figure 54).
-
Clean the grease fittings.
-
Pump the grease into the bearings and the bushings.
-
Clean off the excess grease.
-
Clean and pack the wheel bearings every year or every 300 hours of operation
Daily Checks
At the start of each day, complete these safety checks before operating the machine. Report any safety problems to your supervisor. See the Safety Instructions in this manual for details.
Checking the Tires and Wheels
-
The recommended tire pressure for the tow chassis is 69 kPa (10 psi), or as recommended by the tire manufacturer. Refer to the tow vehicle operator's manual for the tow vehicle tire specifications.
-
Check for excessive wear or visible damage.
-
Check that the wheel bolts are tight and none are missing.
Checking the Rear Gate
Check that the adjustable section of the rear gate opens and closes without sticking.
Stowing and Checking the Jack Stands
-
Safely stow the jack stand(s) in the up position before traveling. On Truckster direct connect chassis stow the jack stands on the rear of the machine.
-
Check that the hitch pin and jack stand are not damaged, and the safety pin is in place. (Replace safety pins if missing or damaged).
-
Check that the hitch connections are not loose.
Checking the Hydraulic System
Warning
Hydraulic fluid escaping under pressure can penetrate skin and cause injury.
-
Make sure 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.
-
Seek immediate medical attention if fluid is injected into skin.
-
Check the hydraulic system for fluid leaks. If you find a leak, tighten the fitting, or replace or repair the damaged part.
-
Check the hydraulic hoses for wear or visible damage.
-
Check the hydraulic fluid level. Fill up if necessary.
Checking the Belt and Rear Gate Seals
-
Check all rubber seals for wear or damage. Replace or repair the seals if any leakage occurs.
-
Check and adjust the conveyor belt cleaning scraper. Ensure that the scraper is in full contact with the belt across its length.
Checking Other Components
-
Check the blades on the Twin Spinner discs for wear. Replace when they wear thin.
-
Check the Twin Spinner housing for signs of cracking or corrosion. Replace wear plates as required
-
Check that the safety decals are undamaged and legible, otherwise, replace them.
Hydraulic System
The machine is shipped from the factory filled with high-quality hydraulic fluid. Check the level of hydraulic fluid before the machine is first started and daily thereafter. The recommended replacement fluid is as follows:
Toro PremiumTransmission/Hydraulic Tractor Fluid (Available in 5 gallon pails or 55 gallon drums. See parts catalog or Toro distributor for part numbers.) |
Alternative fluids: If the specified fluid is not available, other universal tractor hydraulic fluids (UTHF) may be used, but they must be only conventional, petroleum-based products, not synthetics or biodegradable fluids. The specifications must fall within the listed range for all of the following material properties and the fluid should meet listed industry standards. Check with your fluid supplier to see if the fluid meets these specifications.
Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendation.
Material Properties: | |
Viscosity, ASTM D445 | cSt @ 40°C (104°F) 55 to 62 |
Viscosity Index ASTM D2270 | 140 to 152 |
Pour Point, ASTM D97 | -37°C to -43°C (-35°F to -46°F) |
Industry Specifications: API GL-4, AGCO Powerfluid 821 XL, Ford New Holland FNHA-2-C-201.00, Kubota UDT, John Deere J20C, Vickers 35VQ25, and Volvo WB-101/BM | |
Note: 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. 1 bottle is sufficient for 15 to 22 L (4 to 6 US gallons) of hydraulic fluid. Order Part No. 44-2500 from your authorized Toro distributor.
Maintaining the Conveyor Belt System
Checking the Conveyor Belt and Rollers
-
Check that the conveyor belt is tracking straight on the rollers and does not slip. Make adjustments if necessary. Refer to Adjusting the Tracking of the Conveyor Belt.
-
Check the front and rear roller bearings every 2 months for wear or visible damage.
-
Check the condition and tension of the drive chain and the sprockets.
Important: Check for trapped spreading material between conveyor bed, belt, and rollers. Refer to Washing the Machine.
Adjusting the Conveyor Belt Tension
Perform the tensioning procedure only if the belt is slipping, if it has been replaced, or if it has been loosened to replace other parts.
-
Place the belt’s V-guide in the guides of the front and rear rollers.
-
Tighten the 2 belt adjustment nuts evenly until the belt is snug.
Note: If necessary, remove the front idler roller cover and the rear chute cover.
-
Fully load the machine with the heaviest material you expect to use.
-
With 2 wrenches, hold the end of the tensioner rod stationary and then loosen the locking nut, which is the nut closest to the end of the rod (Figure 55).
-
Turn the conveyor belt on and check if the belt is slipping.
-
If so, stop the belt and tighten both adjuster nuts half a turn. Do not over-tension.
-
Repeat steps 5 and 6 until the conveyor belt stops slipping.
-
Tighten the locking nuts and install the yellow safety covers
Adjusting the Tracking of the Conveyor Belt
The conveyor belt system is self-tracking. Both the front and rear rollers have a groove in the middle for the belt’s V-guide to run in. Sometimes, the belt may track outside the grooves. To track the belt, do the following:
-
Determine which side the belt is tracking towards.
-
Remove the safety covers from both front corners.
-
On the side the belt is tracking towards, hold the end of the tensioner rod stationary, then loosen the locking nut and tighten the adjuster nut by 2 flats of the nut (Figure 55).
-
Tighten both locking nuts and turn on the conveyor belt.
-
Check the tracking movement. Repeat the above steps until the belt tracks back to the correct position.
Important: Be patient! Do not over-tension the belt.
-
Install both of the safety covers.
Washing the Machine
Salts, road tar, tree sap, fertilizers, or chemicals may damage the painted finish of the machine. Wash off these deposits as soon as possible with detergent and water. Additional cleaners or solvents may be needed, but ensure that they are safe for painted surfaces.
Warning
Flammable fluids and cleaners with toxic vapors are hazardous to your health.
Do not use flammable fluids or cleaners with toxic vapors. Follow the manufacturer’s recommendations.
Important: Do not use a high-pressure washer. This can remove paint, safety decals, and grease, and can also damage components.
-
Remove the option before cleaning and wash it separately.
-
Remove the handheld remote.
-
Wash the body of the machine with warm water and a mild detergent
-
Completely rinse off the detergent residue with clean water before it dries.
-
Remove the belt cleaning scraper assembly from the rear of the machine (Figure 56).
-
Raise the front of the machine as high as necessary.
-
If you have a truck-mounted machine, use the lift cylinder on the tow vehicle. (See the tow vehicle’s owner’s manual.)
-
If you have a tow-behind or Truckster direct connect chassis, use the jack stand on the chassis.
-
Fully open the rear gate and spray water inside the hopper assembly and the rear gate area. Inspect the side seals and replace if necessary.
-
Locate the clean-out decal on the front of the machine (Figure 57), using a garden hose, spray through the front guard mesh until the belly pan is completely clear of material (Figure 58).
Note: When the covers are removed for greasing, take the opportunity to wash out any trapped spreading material.
-
Inspect the hopper, bottom guard, conveyor belt, bed, and rollers to ensure that all trapped material is gone.
-
Lower the machine back into the normal operating position
-
Install the belt cleaning scraper assembly. Push the scraper mount bar onto the belt. Ensure that the scraper is as vertical as possible, but still in contact with the belt.
