Safety Precautions ❏ Keep the working area 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.
Safety Precautions (cont.) ❏ 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.
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 10w-30 / 10w-40 / 15w-40 non-synthetic engine oil before use or serious damage will occur.
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 / 10w-40 / 15w-40 non-synthetic engine oil. Fill to the correct level before use. 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.
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.
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 the side.
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.
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 park brake before leaving the controls. 3. Shut off the engine by pressing the on/off switch.
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.
❏ 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. Transportation The stump grinder is designed to be transported via a van or small trailer. The machine is equipped with grab bars that are to be used for both lifting the machine and strapping it down.
