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.
OIL AND FUEL INFORMATION OIL AND FUEL MIXING INSTRUCTIONS To Obtain Correct Fuel Mix: Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded gasoline in a separate fuel can. Use a 40:1 fuel/oil ratio. Do not mix them directly in the engine fuel tank. See the table below for specific gas and oil mixing ratios. Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use fresh (less than 60 days old) clean unleaded fuel.
STARTING/STOPPING INSTRUCTIONS IMPORTANT: Experience indicates that alcohol blended with fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine when in storage. To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until fuel lines and carburetor are empty.
STARTING/STOPPING INSTRUCTIONS STOPPING INSTRUCTIONS 1. Release the trigger and allow the engine to return to the idle speed. 2. Move the STOP switch to the STOP position (Fig. 4). F C E NOTE: For emergency stopping, push the lever of the chain brake lever/hand guard (C) forward and move the STOP switch up (Fig. 3, 4). STARTING A COLD ENGINE B 1. Slide the STOP switch down (Fig. 4). The red choke lever (H) has 3 positions: Positions 1, 2 and 3 (Fig. 6). 2.
STARTING/STOPPING INSTRUCTIONS WARNING: Activate the CHAIN BRAKE® slowly and deliberately. Keep the chain from touching anything; don’t let the saw tip forward. WARNING: L If chain does not stop, turn engine off and take your unit to the nearest Authorized Service Center for service. CHAIN BRAKE TEST 1. Place saw on a clear, firm, flat surface. 2. Start engine. (Refer to previous page) 3. Grasp the rear handle (A) with your right hand (Fig. 10). 4.
OPERATING INSTRUCTIONS FELLING Never walk in front of a tree that has been notched. When felling, keep at least 2 tree lengths away from your fellow workers. 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. Make the felling cut (D) from the other side of the tree and 1.5 - 2.
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. 17). 2. Log supported on 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. 18). 3. Log supported on both ends: First, overbuck 1/3 diameter of log to avoid splintering.
MAINTENANCE AND REPAIR INSTRUCTIONS MAINTENANCE SCHEDULE NOTE: Maintenance, replacement, or repair of the emission control devices and system may be performed by a Sears or other qualified service dealer.

MAINTENANCE AND REPAIR INSTRUCTIONS SAW CHAIN TENSION ADJUSTMENT WARNING: CAUTION: A new saw chain stretches, requiring adjustment after as few as 5 cuts. This is normal with a new chain, and the interval between future adjustments will lengthen quickly. Always use protective gloves when 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.
MAINTENANCE AND REPAIR INSTRUCTIONS MAINTENANCE REQUIREMENTS CHECK FOR DAMAGED OR WORN PARTS Check a Sears Service Center for replacement of damaged or worn parts. NOTE: It is normal for a small amount of oil to appear under the saw after the engine stops. Do not confuse this with a leaking oil tank. B • STOP Switch - Ensure STOP switch functions properly by moving the switch to the STOP position. Make sure the engine stops; then restart engine and continue.
MAINTENANCE AND REPAIR INSTRUCTIONS OIL FILTER SPARK PLUG NOTE: Drain oil reservoir before changing filter NOTE: For efficient operation of saw engine, spark plug must be kept clean and properly gapped. 1.

MAINTENANCE AND REPAIR INSTRUCTIONS STORING A CHAIN SAW Sprocket Tip Lubrication CAUTION: Storing a chain saw for longer than 30 days requires storage maintenance.

Remove the fuel tank cap slowly to release any pressure in tank.
MAINTENANCE AND REPAIR INSTRUCTIONS GUIDE BAR MAINTENANCE: Chain Lubrication Most guide bar problems can be prevented merely by keeping the chain saw well maintained. Insufficient guide bar lubrication and operating the saw with chain that is too tight will contribute to rapid bar wear. To help minimize bar wear, the following guide bar maintenance procedures are recommended.
