SAFETY PRECAUTIONS
• Keep the working area clean and well lit.
• Do not operate the stump grinder in the presence of flammable liquids, gases or dust.
• Keep children and bystanders away while operating the stump grinder. Keep the area
free of all distractions.
• Only responsible, properly instructed indivuals should operate this machine.
• Inexperienced operators must always be carefully supervised.
• Do not expose stump grinders 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 grinders may
result in serious personal injury.
• Use safety equipment. Always wear eye protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce 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.
• Always wear earplugs to protect your ears.
• 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 extraction and collection of dust, ensure these are
connected and properly used. Use of these devices can reduce dust related hazards.
• Check stumps to be removed for embedded nails, wire, metal fence posts and other
metallic objects and for rocks or 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 cutting wheel for damage or missing teeth and replace as
necessary.

OPERATION
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-30/ 15w-40
non-synthetic engine oil. Fill to the correct level before use.
The engine is shipped without oil. Fill to the correct level before use. 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
1. Lock travel wheel by pulling brake lever fully back.
2. Make sure throttle is in slow position.
3. If the engine is cold, move the choke lever to the closed position.
4. Raise the cutter wheel 4 to 5 inches off the ground by pushing downwards on the
handle bar, hold it in that position.
The next step may cause the cutter wheel to rotate, keep everyone away.
5. Pull the starter rope lightly until resistance is felt then pull briskly. Do not allow the
rope to snap back, return it by hand to prevent damage to the starter.
6. Move the choke lever to the open position.
The next step causes the cutter wheel to rotate, keep everyone away.
7. 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 influences 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 the controls when the cutting wheel is rotating.
Operating Tips!
• Use smooth, comfortable side to side movements while operating.
• When it is desired to cut smaller roots, it may be more effective to do so before rather
than after cutting the stump.
• 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 to 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.

• 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 done 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 regularly.
• 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 regularly 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.
