MAINTENANCE SAFETY
In general
- Maintain machine according to manufacturer’s schedule and instructions for maximum safety and best results.
- Park the machine on level ground.
- Never allow untrained personnel to service machines.
- Guards should only be removed by qualified maintenance technicians for maintenance/service. Replace when work is complete.
- Adjust or repair only after the engine has been stopped and the blade has stopped moving.
- Disconnect spark plug wire(s) before doing any maintenance.
- Replace parts if worn, damaged, or faulty. For best results, always replace with parts recommended by the manufacturer.
- Do not dismantle the machine without releasing or restraining forces which may cause parts to move suddenly.
- Provide adequate support, e.g. jack stands for lifted machine or parts if working beneath.
- Do not put hands or feet near or under rotating parts.
- Clean up spilled oil or fuel thoroughly.
- Replace faulty mufflers.
- To reduce fire hazards, keep the engine, muffler, and fuel storage area free of grass, leaves, debris buildup or grease.
Blades
The sod cutter blade is sharp and can cut. Use extra caution when handling.
Remove obstructions with care. Wrap the blade or wear gloves.
- Only replace the blade. Nev-straighten or weld.
- Keep other persons away from blades.
Fuel
- Gasoline and diesel fuels are flammable; gasoline vapors are explosive. Use extra care when handling.
- Store only in containers specifically designed for fuel.
- When refueling or checking fuel level:
- Stop the engine and allow to cool;
- Do not smoke;
- Refuel outdoors only;
- Use a funnel;
- Do not overfill;
- If fuel is spilled, do not attempt to start the engine until the spill is cleaned up and vapors have cleared.
- Replace caps on fuel containers and tanks securely.
Sparks from static electricity can start fires or cause explosions. Flowing fuel can generate static electricity. To prevent static electricity sparks:
- Keep fuel containers electrically grounded. Do not fill containers in a vehicle or on a truck or trailer bed with a plastic liner. Fill containers on the ground away from the vehicle.
- When practical, remove petrol (gas) powered equipment from the truck or trailer and refuel it on the ground. If equipment must be refueled on the truck or trailer, refuel from a portable container rather than a dispenser nozzle.
- Keep the dispenser nozzle in contact with the rim of the fuel tank or container opening until fueling is complete. Do not use a nozzle lock-open device.
Storage Safety
- Stop the engine and allow to cool before storing.
- Drain the fuel tank outdoors only.
- Store fuel in an approved container in a cool, dry place.
- Keep the machine and fuel containers in a locked storage place to prevent tampering and to keep children from playing with them.
- Do not store the machine or fuel container near heating appliances with an open flame, such as a water heater, or an appliance with a pilot light.
- Keep gasoline (petrol) storage area free of grass, leaves and excessive grease to reduce fire haz-ard.
- Clean grass and debris from cutting units, drives, mufflers and engine to help prevent fires.
SET UP/MAINTENANCE
SET UP INSTRUCTIONS
To prevent injury, wear appropriate eye protection and stand clear when
cutting banding. Banding is under ten-sion and may snap back when cut.
- Remove crate top, ends, sides and plastic covering the unit. Remove the banding attaching the sod cutter to the pallet.
- Roll the sod cutter off the pallet. The unit can also be driven off the pallet, but first read the Safety, Con-trols, and Operation sections of your manuals, then check the oil and add fuel.
- Dispose of pallet, box, and banding in a responsible manner.
GENERAL MAINTENANCE
To keep the sod cutter in good operating condition, perform the following:
- Keep blade sharp; a sharp blade cuts cleaner, faster and more uniformly and places less load on the machine. Sharpen cutting edge on bevel or top side only.
- Keep drive belt at proper tension and free of oil and dirt at all times.
- Check engine oil level and air filter element daily.
- Check for loose bolts and connections.
- All grease fittings are pressurized type. Use a good grade Lithium Base Grease or equivalent. Grease eccentric arms sparingly every 4 hours of service, all others daily. Wipe off all grease fit-tings before and after each greasing (there are a total of 8 grease fittings).
- To make sure the chain on the front drive wheels is tight, you will need to remove the chain guard to check this. If tightening is required, loosen nuts and bolts on the 3/4” pillow block bearings and push the bearings toward the back of the sod cut-ter until chain is tight. Make sure both bearings go back evenly to keep jackshaft running even with the frame. After doing this, retighten nuts and bolts on the bearing and replace the chain guard.
- Engine (refer to manufacturer’s owner’s manual).
Engine Oil Level Check
- BEFORE CHECKING OIL:
- make certain the engine is level
- the engine switch is in the OFF position
- the sod cutter blade is NOT engaged
- the drive wheels are disengaged.
- Remove the filler cap/dipstick and wipe it clean.
- Insert and remove the dipstick without screwing it into the filler neck. Check the oil level shown on the dipstick.
- If the oil level is low, fill to the edge of the oil filler hole with the recommended oil. SAE 10W-30 is recommended for general use. Refer to engine oil recommendations in engine manual for other viscosities and information.
- Screw in the filler cap/dipstick securely.
Transmission Oil Level Check
- Check the transmission oil level with the engine stopped and in a level position.
- Remove the filler cap/dipstick and wipe it clean.
- Insert and remove the dipstick without screwing it into the filler hole. Check the oil level shown on the dipstick.
- If the oil level is low, add oil to reach the upper limit mark on the dipstick. Use the same oil that is recommended for the engine, SAE 10W-30.
- Screw in the filler cap/dipstick securely.
STORAGE
STORAGE INSTRUCTIONS
WARNING
To prevent possible explosion or ignition of vapor-ized fuel, do not store
equipment with fuel in tank or carburetor in enclosure with open flame (for
example, a furnace or water heater pilot light).
Daily Storage
- Check engine oil level and air filter element daily.
- Check oil level in gear case. Hydro gear uses 20W50 oil.
- Close fuel valve at bottom of fuel tank.
- Clean cutting blade (grass, dirt, etc.).
Extended Storage
Before the equipment is put into storage for any period exceeding 30 days:
- Drain all fuel from fuel tank and lines (use a hose or fuel line, routed from fuel tank shut-off to proper container).
- Start engine and run until all fuel is used from the carburetor float bowl.
- While engine is warm, check the transmission oil and refill with the proper weight of oil corre-sponding to the season when the equipment will next be used.
- Remove the spark plug and squirt a small quan-tity of engine oil into the cylinder. Turn the engine over a few times to distribute the oil.
- Lubricate all lubrication fittings.
- Clean and oil cutting blade to prevent rust.
To put equipment into operation after an extended storage:
- Fill fuel tank with clean fresh fuel.
- Check crankcase oil level, and start engine.
- Check fuel system for fuel leaks.
WARNING
- When replacement parts are required, use genuine Classen parts or parts with equivalent characteris-tics, including type, strength and material. Failure to do so may result in product malfunction and possible injury to the operator and/or bystanders.
- Carbon monoxide present in the exhaust is an odor-less and deadly gas. Never start or run the engine inside where exhaust fumes can collect. Provide enough fresh air to keep fumes from getting too strong.
- Replace any warning decal that becomes illegible immediately.
