RULES FOR SAFE OPERATION SYMBOL The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols, and their explanations, deserve your careful attention and understanding. The safety warnings do not by themselves eliminate any danger. The instructions or warnings they give are not substitutes for proper accident prevention measures. SYMBOL MEANING DANGER: Failure to obey a safety warning will result in serious injury to yourself or to others.
RULES FOR SAFE OPERATION • Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw’s chain stops moving when the trigger is released. WARNING: KICKBACK may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse reaction, kicking the guide bar up and back towards the operator.
RULES FOR SAFE OPERATION OTHER SAFETY PRECAUTIONS ELECTRICAL SAFETY WARNINGS • Do not operate a chain saw with one hand! Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chain saw is intended for two-handed use. • Since the tool is double-insulated, a 2-wire extension cord (an extension cord without a ground) may be used.
RULES FOR SAFE OPERATION ELECTRICAL SAFETY WARNINGS (CONT’D) • Examine the electrical switches. Do not use the chain saw if the switches do not properly turn on and off. Do not attempt to make any repairs to the electric switches. Take your saw to a Sears or other qualified service dealer. • CORD SETS: Make sure your cord set is in good condition, with a cord that is heavy enough to carry the current that your unit will draw.

RULES FOR SAFE OPERATION cont. KICKBACK SPECIFICS KICKBACK SPECIFICS Pinch Kickback WARNING: Kickback can lead to dangerous loss of control of the chain saw and result in serious or fatal injury to the saw operator or to anyone standing close by. Always be alert. Rotational kickback and pinch-kickback are major chain saw operational dangers and the leading cause of most accidents. Pinch kickback can occur when the saw chain is pinched along the bottom or top of the guide bar.
STARTING/STOPPING INSTRUCTIONS WARNING: Never operate the saw without the bar and Oil Reservoir Inspection Spot chain properly installed. Oil Cap STOPPING INSTRUCTIONS The saw motor will automatically stop when the trigger is released. To restart the motor, you will have to depress the LOCK/OFF button and squeeze the trigger. STARTING INSTRUCTIONS 1. Fill the oil reservoir with correct chain and bar oil (Fig. 3). Use a funnel, wipe up any spills and make sure no dirt gets into the tank.
OPERATING INSTRUCTIONS FELLING WARNING: Felling is the term for cutting down a tree. Small trees up to 6-7 inches (15-18cm) in diameter are usually cut in a single cut. Larger trees require notch cuts. Notch cuts determine the direction the tree will fall. Never walk in front of a tree that has been notched. Make the felling cut (D) from the other side of the tree and 1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C) (Fig. 9).
OPERATING INSTRUCTIONS When bucking on a slope, always stand on the uphill side. 1. Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting into the ground (Fig. 13). 2. Log supported on one (1) end: First, cut from bottom (underbuck) 1/3 diameter of log to avoid splintering. Second, cut from above (overbuck) to meet first cut and avoid pinching (Fig. 14). 3. Log supported on both ends: First, overbuck 1/3 diameter of log to avoid splintering.
MAINTENANCE AND REPAIR INSTRUCTIONS MAINTENANCE SCHEDULE WARNING: To prevent serious injury, never perform maintenance or repairs with unit running. Always service and repair a cool unit. Perform these required maintenance procedures at the frequency stated in the table. These procedures should also be a part of any seasonal tune-up. A good preventive maintenance program of regular inspection and care will increase life and improve performance of your chain saw.
MAINTENANCE AND REPAIR INSTRUCTIONS Install Saw Chain REPLACING THE GUIDE BAR WARNING: CAUTION: Disconnect the chain saw from power source before checking or adjusting the chain saw tension. Always use protective gloves when handling the saw chain. 1. Spread the chain out with the cutting edges (H) of the chain pointing in the DIRECTION OF ROTATION. 2. Fit chain into groove of guide bar. NOTE: The chain must be installed in the correct direction (Fig. 20). These instructions are for replacing a bar.
MAINTENANCE AND REPAIR INSTRUCTIONS SAW CHAIN TENSION ADJUSTMENT WARNING: Always use protective gloves when D handling the saw chain. Proper tension of saw chain is extremely important and must be checked before starting, as well as during any cutting operation. Taking the time to make needed adjustments to the saw chain will result in improved cutting performance and prolonged chain life. NOTE: A new chain and bar will need readjustment after as few as 5 cuts.
MAINTENANCE AND REPAIR INSTRUCTIONS CHAIN AND BAR LUBRICATION The Chain Brake® is a safety feature which is activated if pressure is applied against the guard or when, in the event of kickback, the operator’s hand strikes the lever. When the Chain Brake® is activated, chain movement abruptly stops and the power supply to the motor is immediately cut off. The purpose of the Chain Brake® is to reduce the possibility of injury due to kickback.
MAINTENANCE AND REPAIR INSTRUCTIONS CHAIN BRAKE® TEST DOUBLE INSULATION Before cutting with your saw, the Chain Brake® should be tested as follows: A. Make sure the Chain Brake® is disengaged (Fig. 26). B. Place the saw on a firm, flat, dry surface that is clear of any debris. Do not let the saw come in contact with any objects. C. Plug the unit into the power source. D. Grasp the front handle (not the Chain Brake®/Hand Guard Lever) with your left hand. Thumb and fingers should encircle the handle. E.
MAINTENANCE AND REPAIR INSTRUCTIONS GUIDE BAR MAINTENANCE Maintenance Procedures Frequent lubrication of the guide bar is required. Proper maintenance of the guide bar, as explained in this section, is essential to keep your saw in good working condition. Most guide bar problems can be prevented merely by keeping the chain saw well maintained. Incorrect filing and non-uniform cutter and depth gauge settings cause most guide bar problems, primarily resulting in uneven bar wear.
MAINTENANCE AND REPAIR INSTRUCTIONS CHAIN MAINTENANCE WARNING: Never have more than 3 links removed from a loop of chain. This could cause damage to the sprocket. WARNING: Unless you have experience and specialized training for dealing with kickback (see Safety Precautions), always use a lowkickback saw chain, which significantly reduces the danger of kickback. Low-kickback saw chain does not completely eliminate kickback.
TROUBLESHOOTING UNIT WILL NOT START CAUSE ACTION 1. Unit is unplugged 1. Check cord to make sure it is plugged into an electrical outlet 2. GFCI in outlet has tripped (if used) 2.
