WARNING: Failure to follow the proper protocols listed in the manual may cause personal injury to the operator or damage the equipment.

Safety Precautions

• Work area should be clean and well lit.

• Do not operate the stump grinder in the presence of flammable liquids, gasses, or dust.

• Keep children and bystanders at least 50 feet away while operating the stump grinder.
  Stop the engine when another person or pet approaches.

• Only responsible, properly instructed individuals should operate this machine.

• Inexperienced operators must always be carefully supervised.

• Do not expose the stump grinder to rain or wet conditions.

• Stay alert, watch what you are doing and use common sense when operating a stump grinder.
  Do not use a stump grinder while you are tired or under the influence of drugs, alcohol, or medication.
  A moment of inattention while operating any stump grinder may result in serious personal injury.

• Use safety equipment. Always wear eye protection. Safety equipment such as a dust-mask, non-skid safety shoes, hard hat, and hearing protection used for appropriate conditions will reduce risk of personal injuries.

• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts.
  Loose clothes, jewelry or long hair can be caught in moving parts.

• Use ear protectors or ear plugs rated for at least 20 dba to protect your hearing.

• Do not start the engine until the machine is in the cutting position next to the stump.

• Do not overreach. Keep proper footing and balance at all times.
  This enables better control of the stump grinder in unexpected situations.

• If devices are provided for the collection of dust extraction, ensure that that these devices are connected and properly used. Use of one of these devices can reduce dust related hazards.

• Check stumps to be removed for embedded nails, wire, metal fence posts, rocks, and other buried impediments which may become dangerously thrown or cause unexpected machine movements when hit by the cutting wheel.

• Make sure that all shields and guards are in place and are in good condition prior to operating the machine.
  Check the cutting wheel for damage or missing teeth and replace as necessary.

• Ensure that everyone in the vicinity is aware of the danger zone associated with this machine.
  Any person must avoid the danger zone at all times when the machine is in operation.
  

• Make sure that no one is working on, underneath, or close to the machine before starting the engine or beginning to move the machine. Make sure that the area is free of personnel.

• Don’t make alterations or modifications to your stump grinder.

• Check with your local council and utility providers for the locations of buried pipes and cables where applicable.
  Do this before operating the machine.

Fuel Safety

WARNING: Pay attention and use extreme care while handling fuel.
Fuel is extremely flammable and the vapors are highly explosive

• Never remove the fuel cap or add fuel with the machine running.
  Stop the engine and allow engine and exhaust components to cool before refueling or storing.

• Add fuel outdoors in an open area. Do not smoke while adding fuel.

• Fill your engine with engine oil (check Kohler Manual for oil type) before use or serious damage will occur.

• Never refuel or store the machine in a place where there is an open flame, spark, or other ignitable objects.

• If you spill gasoline, do not attempt to start the engine.
  Move the machine away from the area of the spill and avoid creating any source of ignition until the gas vapors have dissipated.
  Wipe up any spilled fuel to prevent a fire hazard and properly dispose of the waste.

• Always make sure the fuel cap is securely tightened and replace before starting.

• If the fuel tank needs to be drained, it should be done outdoors.

• The muffler and engine become very hot and can cause severe burn. Do not touch.

Used to loosen the bow handle, make adjustment to bow handle, and tighten to keep secure.
| Top lever is Choke and bottom lever is Fuel.
Choke is used to close the air way and enrich the fuel mixture ratio. This is used during cold starts to assist the engine during start up.
The Fuel lever is to allow fuel from the gas tank to the carb.
It is also used to shut off the machine.
| Engine recoil starter.
Used to pull start the engine.
| Oil reservoir dip stick.
There is one on each side of the engine and they both go into the same reservoir.
This is used to fill the engine with oil.
Can also be used to check and make sure the correct amount of oil is used.
The bolt on the bottom left of the photo is used to drain the oil.
Use aluminum foil to direct the oil to a container to keep the unit clean.

Operations

Adding Oil to the Engine

1. Only fill the fuel tank to a level 15mm lower than the top of the fuel tank. Do not overfill.

2. Use the dipstick to check the oil level. Use 10w-30 engine oil (Kohler manual will list other options depending on environment).
   Fill to the correct level before use.

3. Both yellow fill plugs go to the same reservoir. Fill with whichever side is accessible.
   

NOTE: The engine is shipped without oil.
Operating the engine with no oil or oil at a low level will destroy the engine.
This is not covered under warranty.

Starting the Engine

• Lock the travel wheel by pulling the brake lever back fully.
• Make sure throttle is in slow position.
• Make sure emergency stop pull is installed and palm stop switch is reset by twisting right.

Do not allow the rope to snap back. Set it back by hand to prevent damage to the starter.

• If the engine is cold, move the choke lever to the closed position.
• Raise the cutter wheel 4 to 5 inches off the ground by pushing downwards on the handle bar and hold it in that position.

This next step may cause the cutter wheel to rotate. Keep everyone away.

• Pull the starter rope lightly until you feel resistance, then pull briskly.

• Or insert key in ignition and turn to start position. Once the engine fires, release key and it will go to the on position.

• Move the choke lever to the open position.
  The next step causes the cutter wheel to rotate. Again, keep everyone away.

• Move the throttle to fast. If the engine is cold, allow the engine to idle (throttle set to slow) for a few minutes before cutting

Removing Stumps

• Remove all loose pieces of wood, stones, wire and other debris from the area before beginning stump removal.

• Wind direction should be considered, as it will influence the direction in which dust and wood chips are directed.

• Never operate the grinder after dark. There will be no adequate light for the operator to use the grinder safely.

• Always allow a cold engine time to warm up before cutting a stump.

• Only the portion of cutting wheel within the 80-degree area shown below should engage the stump.
  Never undercut the stump or use the bottom of the cutting wheel for cutting purposes.
  

• Never leave controls when the cutting wheel is rotating.

• Do not angle engine more than 25 degrees while in operation.
  Doing so can cause damage to the engine.
  

Operating Tips

• Use smooth and comfortable side to side movements while operating.

• When you need to cut smaller roots, it may be more effective to do so before cutting the stump, rather than after.

• Should the chip build-up become excessive when cutting, shut off the machine, wait for the cutting wheel to stop rotating, retract the machine from the stump and rake away the chips.
  It is also possible to use the cutter wheel to push chips off the side.

• In order to prevent any of the wheels becoming stuck in the hole.
  Move the grinder to the other side of the stump to continue removal or by filling the hole with chips before continuing.

You will want to prepare the grinder at the stump by placing it into position with the cutting wheel near the top edge of the stump.
(See image below)

Removing Roots

1. Make sure the throttle is set to fast. The cutter wheel will accelerate to cutting speed.
2. Swing the cutting wheel to one side, then lower it into the nearest roots that are buried at the foot of the stump.
3. Swing the cutting wheel before each sweep until the roots are sufficiently removed.
   

Cutting the Full Stump

1. Make sure the throttle is set to fast. The cutter wheel will accelerate to cutting speed.
2. Direct the cutter wheel against the stump, beginning with the nearest top corner of the stump. Steadily sweep it across the stump left and right, cutting away a ½ inch of wood with each sweep.
3. Raise and lower the cutter wheel between sweeps by lowering and raising the control handle.
4. Roll the machine forward and back by pushing and pulling on the control handle.
   To do this, release the brake. Relock it when the machine has been repositioned and continue cutting.
   
   Continue with the final removal of roots
   Cut the remaining roots as described in step 2 until satisfactorily removed.

Shutting Off the Grinder

1. When stopping the machine after normal operation, lower the engine speed to slow and press the emergency switch.
2. Set the brake before leaving the controls.
3. The fuel line lever is also an On/Off switch for the engine.

Standard Shutdown Procedure
In consideration of your own safety and that of other, you should always use the following normal shutdown procedures before departing from the controls for any reason including cleaning, servicing, transporting, or inspecting the stump grinder.
Never deviate from this procedure unless instructed in this manual or in an emergency that requires it.

WARNING: A rotating cutting wheel is very dangerous.
Stand at controls and ensure that the cutting wheel comes to a complete stop before doing anything else.

1. Move the engine throttle to the slow position.
2. Push the emergency (on/off) switch to stop the engine.
3. Set park brake before leaving controls.

Emergency Shutdown Procedure

1. Immediately press the emergency (on/off) switch to stop the engine.
2. Be sure to allow all moving parts to come to a complete stop.
3. Pull the brake lever to engage the brake.
4. Rectify the emergency situation and return to normal operation.

Emergency Stop Reset
Reinstall emergency stop pull and twist the palm stop switch to the right.
Palm stop switch will pop up when reset.

Maintenance

• Make sure all nuts, bolts, and screws are tightened.

• Never store the equipment with petrol in the tank inside a building where fumes can reach an open flame or spark.
  Allow the engine to cool before moving the grinder.

• To reduce fire hazards, keep the engine and petrol storage area free of grass, dirt, and excessive grease.

• Replace worn or damaged parts for safety. If the fuel tank has to be drained, this should be outdoors.

• Regularly check the oil level and add some oil or replace it if necessary.

• Frequently check the grinder and ensure that all bark and dirt deposits are removed from beneath the deck.

• Lubricate the wheel axle and the bearings with grease about once per season.

• Check the cutting wheel often. In order to achieve clean work, the blade should always be sharp and well balanced.

• Check the tightening of all bolts and screws at regular intervals. Nuts and bolts that are worn out or badly tightened can damage the engine or the frame.

• If the grinder hits an obstacle violently, stop the grinder and take it to a specialist for inspection.
