MAINTENANCE

MAINTENANCE

Stop the engine, ensure the blades stop rotating, and remove spark plug wire before performing any maintenance. When replacement parts are required, use genuine Classen parts. Failure to do so may result in product malfunction and possible injury to the operator and/or bystanders, and voids the warranty. Carbon monoxide present in the exhaust is an odorless and deadly gas. Never start or run the engine where exhaust fumes can collect. Provide enough fresh air to keep fumes from getting too strong. Replace any warning decals that become illegible immediately.

Maintenance Procedure

Each Use

Tighten any hardware (nuts, bolts, etc.) that are found loose.

X

Replace any broken or missing hardware (nuts, bolts, etc.)

X

Check engine oil

X

Check engine air filter

X

Check tire pressure

X

Check blades for damage and wear

X

Ensure seed gate opens and closes freely

X

Check for debris near wheels and under machine

X

Check to see that set screws on pulley are tight

Check condition of belts, guards, blades for damage or wear

Lubricate all linkages

Every 25 Hours
X X X X

MAINTAINING TIRE PRESSURE
Check the tire pressure before each use. The maximum air pressure is not to exceed 40 psi (176 kPa).

LUBRICATING LINKAGES
Every 25 hours lubricate all linkages with dry-film Teflon lubricant. NOTE: Use a dry coating lubricant to avoid attraction of dirt.
BLADE ROTATION
Check the blades before each use. If the blades are worn on one side, it is possible to rotate them.

1. Turn the engine to the OFF position, ensure the blades stop rotating, and remove the spark plug cable.
2. Thoroughly inspect the blades for cracks and wear. If a blade is worn, it is recommended to rotate or replace all blades at once. If blades are installed at different lengths, then slicing application will not be consistent. Additionally, the blades may inadvertently be lowered beyond 1/4″ into the ground, resulting in damage to the machine.
3. Remove two bolts and nuts holding a blade. Rotate the blade 180°, so the beveled side of the blade

180°
faces away from the shaft assembly. 4. Reinstall on shaft with bolts and nuts in orientation
removed. 5. Repeat for all blades. 6. Reinstall Blade Assembly following `Blade Assembly

Grease front wheel bearings: 1. Turn engine to the OFF position, ensure the
blades stop rotating, and remove the spark plug cable.
2. Use two people for this step. One person pushes down on the handles until the front wheels are slightly elevated off of the floor. The second person inserts a block of wood under the front hopper. Do not lower machine onto block until the second person is away from the machine.
3. Remove the wheel e-rings and washers on both front wheels. Remove wheels and keys, do not lose wheel keys.
4. Connect the grease gun and pump approximately 0.1 ounces of grease (one standard pump) into each bearing. NOTE: Over-packing a bearing with grease can result in overheating of bearing and premature wear.
5. Slide wheels on machine and align the wheel keyhole with the shaft keyhole and reinsert keys. Reinstall washers and e-rings.
6. Use two people for this step., One person push down on the handles until hopper is slightly elevated off of block. The second person removes block, When the second person is away from the machine, carefully lower the machine.

Classen Warranty Statement
2-Year Limited Warranty
This Classen Product is warranted against defects in materials and workmanship for a period of two (2) years from the date of purchase from an authorized dealer under the following terms and conditions. Schiller Grounds Care’s responsibility under this limited warranty is restricted to repairing or replacing, at its option, any covered part found to be defective in material or workmanship during the warranty period. All parts replaced under warranty will be considered as part of the original product and any warranty on the replaced parts will expire coincidentally with the original product warranty.
SCHILLER GROUNDS CARE, INC. MAKES NO EXPRESS OR IMPLIED WARRANTIES, REPRESENTATIONS, OR PROMISES EXCEPT THOSE CONTAINED HEREIN. THERE ARE NO OTHER WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. ALL WARRANTIES OTHER THAN THE EXPRESS WARRANTY SET FORTH ABOVE ARE SPECIFICALLY DISCLAIMED. THE DURATION OF ANY IMPLIED WARRANTY, INCLUDING MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, IS LIMITED TO THE DURATION OF THIS WRITTEN LIMITED WARRANTY.
To Obtain Warranty Service – Warranty service must be performed by an authorized Classen dealer. To locate a dealer, please visit: www.classenturfcare.com and click on FIND A DEALER. For further assistance, write or email the Technical Services Department of Schiller Grounds Care
Schiller Grounds Care, Inc. 1028 Street Road Southampton, PA 18966 techservicesupport@schillergc.com
ABOUT YOUR WARRANTY
The warranty period begins on the date of purchase by the original retail or commercial customer from an authorized Classen dealer and is not transferable. Warranty service must be performed by an authorized Classen dealer. If a warranty replacement becomes necessary, the authorized dealer must be prepared to provide the physical component for verification (freight prepaid) upon request from Schiller Grounds Care. Warranty service will be performed without charge to the original purchaser for parts and labor. The original purchaser is responsible for the expense of delivering the equipment, part, or accessory to and from an authorized dealer’s service center. The purchaser is responsible for any premium charged for overtime labor requested by the purchaser and for any service and/or maintenance not directly related to any defect covered under this limited warranty. Proof of purchase will be required to substantiate any warranty claim. Without proof of the initial purchase date from an authorized dealer, the manufacturing date of the product will be used to establish the warranty period.
EXCLUSIONS
This warranty only covers defects in materials or workmanship.
Engines and Other Manufacturers – Schiller Grounds Care makes no warranty with respect to engines or engine parts such as spark plugs, lubricants, starters, and carburetors. The engine warranty is covered by the engine manufacturer. Consult the Operator’s Manual for the engine provided with your product or ask an authorized dealer for the terms and conditions of these warranties. Schiller Grounds Care makes no warranty with respect to other parts not of its manufacture such as tires, batteries, gearboxes, or similar. These other parts may be covered by the warranties of their respective manufacturers.
Wear Items – This limited warranty does not cover damages or defects from normal wear and tear. This limited warranty does not include routine maintenance and normal maintenance parts, including but not limited to tires, batteries, transmissions, clutches, filters, gearboxes, blades, tines, belts, chains, cables, or bearings.
Negligence and Improper Maintenance or Repair – This limited warranty does not cover any equipment that has been subject to lack of reasonable and proper maintenance, misuse, lack of proper storage, or accidents. This limited warranty does not cover any damage to the equipment that is caused by a freight carrier or is the result of failure to follow the operating instructions within the Owner’s Manual. This limited warranty does not cover any defects due to repairs, modifications, or alternations made to the product by anyone other than Schiller Grounds Care or its authorized dealers. In addition, this limited warranty does not cover repairs made necessary due to a lack of proper protection during storage. This limited warranty does not cover damage caused by the use of parts, supplies, or accessories, including, without limitation, filters, spark plugs, carburetors, ignition, drive belts, brakes, gasoline, fuel, oil, or lubricants, which in the reasonable judgment of Schiller Grounds Care, are either incompatible with the product, adversely affect its operation, performance, durability or are other than as recommended in the Operator’s Manual or other operational instructions provided by Schiller Grounds Care.

Classen Warranty Statement
Improper Use – This limited warranty does not cover any Classen Product, part, or accessory that (i) has been subject to misuse, abuse, neglect, negligence, or accident, or that has not been assembled, operated, or maintained in accordance with the operating or maintenance instructions specified in the Operator’s Manual; or (ii) has been altered or modified so as to adversely affect its operation, performance or durability, or that has been altered or modified in ways not approved by Schiller Grounds Care. To the extent permitted by law, neither Schiller Grounds Care nor any company affiliated with it makes any warranties, representations, or promises as to the quality, performance, or freedom from defect of the Classen Product, part, or accessory covered by this limited warranty. The authorized dealer makes no warranty of its own and such dealer has no authority to make any representation, warranty, or promise on behalf of Schiller Ground Care or to modify the terms or limitations of this limited warranty in any way. Other Exclusions – This limited warranty does not include reconditioned, refurbished, used, or demonstration equipment. This limited warranty excludes failures due to acts of nature beyond the manufacturer’s control. Extended Warranty – Schiller Grounds Care disclaims responsibility for any separately purchased extended warranty. ALL WARRANTIES OTHER THAN THE EXPRESS WARRANTY SET FORTH ABOVE ARE SPECIFICALLY DISCLAIMED. THE DURATION OF ANY IMPLIED WARRANTY, INCLUDING MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, IS LIMITED TO THE DURATION OF THIS WRITTEN LIMITED WARRANTY. Disclaimer of Consequential Damage – Schiller Grounds Care disclaims any responsibility for incidental or consequential damages including, but not limited to, the expense for gasoline, the expense of delivering the product to an authorized service dealer, the expense of returning the product to the purchaser, mechanic’s travel time, telephone charges, rental of a like product during the repair timeframe, travel, loss of revenue, loss of time, or inconvenience. SCHILLER GROUNDS CARE, INC. DISCLAIMS ALL LIABILITY FOR INDIRECT, INCIDENTAL, AND/OR CONSEQUENTIAL DAMAGES IN CONNECTION WITH THE USE OF THE CLASSEN PRODUCTS COVERED BY THIS LIMITED WARRANTY. SOME STATES DO NOT ALLOW LIMITATIONS ON HOW LONG AN IMPLIED WARRANTY LASTS AND/OR DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE LIMITATIONS AND EXCLUSIONS MAY NOT APPLY TO YOU. THIS WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS, AND YOU MAY ALSO HAVE OTHER RIGHTS WHICH VARY FROM STATE TO STATE.
