Once the engine has built up speed, pivot the grinder toward the side of the stump, with a fairly light touch feed straight into the stump. As soon as you feed in, start to swing to the side until you feel the wheel drop off the edge of the stump. Change direction and swing back the other way until you feel it reach the other edge of the stump. As you swing to the side listen to the engine. Provide enough feed to give it a moderate load. If you hear any belt or clutch squealing you are pushing too hard. If you can’t swing it to the side, raise the grinder up. WARNING Keep hands and feet away. Contact with wheel rotating teeth will cause serious personal injury. You can cut roots off by plunging straight through them. When grinding larger stumps, chips may begin to build up under the wheels. Release brake and pull machine towards you so that the "chip pile" is directly under the cutting wheel.

FUEL SAFETY Never refuel while the engine is hot or running. Never smoke or allow naked flames into the area while refuelling. Never inhale fuel vapour. In case of petrol spillage move the machine away from the area of spillage. Always mop up as quickly as possible, and change your clothes if you get fuel on yourself. Always store fuel in a purpose-made sealed container, in a cool, safe place well away from the work area. Avoiding static electricity. Static electricity can initiate from ungrounded gasoline tanks or containers, from flowing gasoline, and from persons carrying a static electric charge. Avoid static electricity by using a portable container made of metal or conductive plastic. It will dissipate the charge to ground more readily. Fill container on the ground. Never fill the container while it is inside a vehicle or on the vehicle bed. Always place container on the ground to be filled. Always dissipate static charge from your body before beginning the fueling process by touching a grounded metal object at a safe distance away from fuel sources. Keep fuel dispenser nozzle in contact with the portable container at all times while filling at a service station. Never fill the grinder's gas tank directly from the service station's fuel dispenser pump – the grinder's tank is not grounded and the high velocity flow of gasoline from a fuel pump can cause static electric build-up.

IDENTIFIER Throttle Control Lever Operator Presence Handle Bar Operator Presence Handle Bar Throttle Control Lever Manual Storage Adjustable Brake Lever Make sure that everyone is warned of what you are doing. Survey the area of work and ensure that there are no stones or any other objects near the tree stump or roots that may interfere with your work. Also check there Before using the machine check the area where the work is going to be carried out. Clear the area of everything that could get in the grinder’s way – stones, metal objects etc. Prepare the machine by locking the handle bar in the upright position. To do it, position T-handle knob and eyebolt so it is on the back side of the hinge bracket, then tighten T-handle knob finger tight. Repeat on other side. To fold it back, turn T-handle knob counterclockwise to loosen. Swing knob and eyebolt to the outside, on both sides of handle. Carefully fold handle downward until it comes in contact with the rubber stops. Now place stump grinder into position with cutting wheel near the front-top edge of the stump. Use brake lever on handle to lock the wheel brake. Turn Fuel to ON position by pushing the bottom knob towards right. If this is first use of the day then switch the choke to the ON position by moving the upper knob towards left. Turn engine switch to the ON position and grip operator presence bar and handle bar together in left hand. Grip the engine pull lead handle and pull gently until you feel the “bite”, then pull on the lead sharply to overcome the pressure, prevent kickback and switch on the engine. Repeat the procedure, if necessary, with the throttle lever in intermediate position. Once the engine is running, return the throttle lever to idle position and gently release the choke lever.
