6. Push in the choke (E) as far it will go. (Fig. 5-2F) 7. Hold the saw securely and tug sharply on the starter 4 times. The engine should start. 8. Let the engine run for 10 seconds to warm up. Press the trigger (F) and put it into idle. (Fig. 5-2G) 9. If the engine does not start up, repeat the above steps. IMPORTANT IDLING INFORMATION In some cases due to operating conditions (altitude, temperature etc.) your chain saw may need a slight adjustment to the idle speed. After warm up - See the User's Manual section 5-2, step 7 - If unit does not Idle after restarting 2 times, follow these steps to adjust idle. 1. Idle adjustment access (G). (Figure 5-2H) 2. Using a Phillips or slotted screwdriver - turn screw 1/4 to 1/2 turn clockwise (to the right). Unit should then idle properly. (Figure 5-2H) NOTE: If chain turns while idling - turn screw back to the left until chain stops and unit continues to idle. 5-1A C A B 5-2A 5-2B A 5-2C B 5-2D 5-2E C D 5-2F A 5-2G F 5-2F 5-2G G GASOLINE McCulloch 40:1 Ratio Lubricant 1 U.S. Gal. 3.2 oz. 95ml (cc) 5 Liters 4.3 oz. 125ml (cc) 1 lmp.

Make sure the on/off switch is in the “I” position. 2. Depress the primer bulb 10 times. 3. Set the throttle latch. Latch throttle advance: depress latch and hold squeeze throttle trigger release trigger and then the latch. 4. Pull the starter rope rapidly 4 times. The engine should start. 5. Release the throttle latch. The throttle latch will be released while you press the trigger. 6. If the engine still can not start, follow the step as “To start engine” section in this user manual. 5-4. TO STOP ENGINE 1. Release trigger and allow engine to return to idle speed. 2. Press STOP switch down to stop engine Figure 5-4A. NOTE: For emergency stopping, simply activate CHAIN BRAKE® and move STOP switch down. INERTIA CHAIN BRAKE® ACTION : NOTE: THIS SAW IS EQUIPPED WITH AN INERTIA CHAIN BRAKE.IF THE SAW KICKS BACK WHILE IN USE, THE INERTIA OF THE MOVING SAW WILL ACTIVATE THE BRAKE. A BRAKE BAND AROUND THE CLUTCH DRUM ACTIVATES AND STOPS THE MOVING CHAIN. 5-5. CHAIN BRAKE® OPERATIONAL TEST Test the CHAIN BRAKE® periodically to ensure proper function. Perform a CHAIN BRAKE® test prior to initial cutting, following extensive cutting, and definitely following any CHAIN BRAKE® service. TEST CHAIN BRAKE® AS FOLLOWS: 1. Place saw on a clear, firm, flat surface. 2. Start engine. 3. Grasp the rear handle (A) with your right hand (Figure 5-5A). 4. With your left hand, hold the front handle (B) [not CHAIN BRAKE® lever (C)] firmly (Figure 5-5A). 5. Squeeze the throttle trigger to 1/3 throttle, then immediately activate the CHAIN BRAKE® lever (C) (Figure 5- 5A). WARNING Activate the CHAIN BRAKE® slowly and deliberately. Keep the chain from touching anything; don’t let the saw tip forward. 6. Chain should stop abruptly. When it does, immediately release the throttle trigger. WARNING If chain does not stop, turn engine off and take your unit to the nearest Authorized Service Center for service. 7. If CHAIN BRAKE® functions properly, turn the engine off and return the CHAIN BRAKE® to the DISENGAGED position. 5-6. SAW CHAIN / BAR LUBRICATION Adequate lubrication of the saw chain is essential at all times to minimize friction with the guide bar. Never starve the bar and chain of oil. Running the saw with too little oil will decrease cutting efficiency, shorten saw chain life, cause rapid dulling of chain, and cause excessive wear of bar from overheating. Too little oil is evidenced by smoke, bar discoloration or pitch build-up. NOTE: Saw chain stretches during use, particularly when it is new, and it will occasionally be necessary to adjust and tighten it. New chain will require adjustment after about 5 minutes of operation. 5-7. AUTOMATIC OILER Your chain saw is equipped with an automatic clutch driven oiler system. The oiler automatically delivers the proper amount of oil to the bar and chain. As the engine speed increases, so does the oil flow to the bar pad. There is no flow adjustment. The oil reservoir will run out at approximately the same time as the fuel supply runs out. 5-4A 5-5A A B C 6 - GENERAL CUTTING INSTRUCTIONS 6-1. FELLING 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. FELLING A TREE: WARNING A retreat path (A) should be planned and cleared as necessary before cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of fall, as illustrated in Figure 6-1A. CAUTION If felling a tree on sloping ground, the chain saw operator should keep on the uphill side of the terrain, as the tree is likely to roll or slide downhill after it is felled. NOTE: Direction of fall (B) is controlled by the...
