IMPORTANT SAFETY INFORMATION Warning – When using an electric chain saw, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and injury to persons, including the following: READ ALL INSTRUCTIONS. Make sure you read and understand all instructions Important Safety Information on pages 2 through 4. Improper use of this chain saw can cause severe injury or death from fire, electrical shock, and body contact with moving chain, on falling wood.
10. Before cutting, always provide the following: Clear work area Secure footing Planned retreat path from falling tree 11. Inspect tree before cutting down. Make sure there are no dead limbs or branches that may fall on you. 12. To reduce the risk of electric shock, this saw has a polarized plug (one blade is wider than the other).This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet of your extension cord, reverse the plug.
16. Carry chain saw from one place to another • With saw stopped and unplugged • By holding front handle (never use hand guard as handle) • With finger off trigger • With guide bar and chain to rear KICKBACK SAFETY PRECAUTIONS Warning – Kickback may occur when the nose or tip of the guide bar touches on object, or when the wood closes in the cut. Tip contact in some cases may cause a lightning fast reverse reaction, kicking the guide bar up and back towards the operation.
EXTENSION CORDS If you use an extension cord, be sure to use one heavy enough to carry the current your electric saw will draw. An improper gauged extension cord will cause a drop in wire voltage resulting in loss of power and overheating. Use only extension cords having an electric rating not less than the rating of the product. The following table shows the correct size to use depending on cord length and machine ampere rating.
ASSEMBLY WARNING - Check the chain tension before each use. Always use protective gloves. Installing the Guide Bar and saw chain 1. Loosen the locking knob counter clockwise and remove the sprocket cover 2. The adjust block should already be attached to the guide bar. Make sure the adjust block is turned all the way counter-clockwise and then put the saw chain on the guide bar. 3. P lace the guide bar onto the bar studs and the chain around the sprocket.
Chain Lubricating Oil Use high quality chain lubricating oil to minimize wear between the saw chain and guide bar while in use. We recommend using SAE No. 30 in the summer and SAE No. 10 in the winter or when cutting resinous wood. Check the oil level prior to each use. Oil tank capacity: 90 cc (3.1 fluid ounces) WARNING - Never use waste or reclaimed oil. This results in damage to the oil pump, saw chain and guide bar.
CUTTING INSTRUCTIONS Before use: Check that the chain brake works properly and is not damaged. Visually inspect the entire saw to ensure all components are free from damage and work properly. Check the chain tension and adjust if necessary. WARNING - Always follow safety procedures. Use the chainsaw only for cutting wood and not other types of materials. Do not use the chainsaw as a lever for lifting, moving or splitting objects.
WARNING - A majority of kickback accidents occur during limbing. WARNING - Never attempt to cut logs while they are in a pile or when a couple of logs are lying together. Such attempts drastically increase the risk of kickback which can result in serious or fatal injury. When bucking, do not stand on the log. Make sure the log will not roll downhill. If bucking on a slope, stand uphill of the log. Limbing – the removal of branches from a felled tree. (Fig.16) Do not use the nose of the guide bar.
MAINTENANCE Guide Bar and Oil Holes Clean guide bar before use. Follow instructions for removing and installing guide bar and saw chain. Remove guide bar and clean groove of the guide bar with a small screwdriver. Clean oil holes with a wire (see below). Check the sprocket and the clutch and clean the bar mount area before installing the bar. Guide bar with sprocket nose should be lubricated with grease using a lubricating syringe.
