Use a funnel when filling the tank and wipe up any spills. Do not let sawdust or other dirt enter the oil tank. The oil filler cap is located adjacent to the front handle. The cap must be tight to ensure proper operation of the oil pump. An automatic pump delivers oil to the barand chain whenever the chain saw is operated. When new and after the tank has been emptied, or after periods of disuse, it may be necessary to prime the pump. This is done by usingthe right handtocontinually runthe saw, and at the same time pressing down on the filler cap with the heel of your left hand covering the small venthole for 5 seconds. Observe all safety precautions.See FIG.20. FIG 11 CHAIN BRAKE OPERATION The brake is actuated if pressure is applied against the lever when, as in the event of “kickback,” the operator's hand strikes the lever. When the brake is actuated, chain movement stops abruptly and the power supply to the motor is cut off, CAUTION: Purpose of the CHAIN BRAKE is to reduce the possibility of injury due to “kickback” but it cannot provide the measure of protection intended if the saw is operated carelessly. CAUTION: Hand placement is important. ALWAYS grip front handledirectly behindthe handguard/chain brake lever (See FIG. 16). The CHAIN BRAKE is disengaged (the chain can move) when the brake lever is pulled back and locked. (FIG. 17). This is the normal running position. The CHAIN BRAKE is engaged (chain is stopped) when the brake lever is in the forward position. (FIG. 18) Before cutting with your saw, test the CHAIN BRAKE as follows: 1. Place the saw on a firm flat surface. 2. Follow the correct procedures to operate the saw. 3. Grasp the rear handle firmly with the right hand. 4. With the left hand, hold the front handle (not the CHAIN BRAKE lever) firmly. (FIG. 16) 5. Squeeze the trigger so that the chain begins to move, then activate (push forward) the CHAIN BRAKE lever (FIG. 18). CAUTION: Activate the CHAIN BRAKE SLOWLY and DELIBERATELY. Be careful to keep the chain from touching any surface: don’t let saw tip forward. 6. The chain should stop abruptly. NOTE: If the chain doesn't stop, shut off the motor. Take the saw to your B & D dealer for repair or replacement of the CHAIN BRAKE. FRONT HANDLE t HANDGUARD/CHAIN- FIG. 17 FIG. 18 10 SAVE THESE INSTRUCTIONS BAR & CHAIN INSTALLATION All Models. REMOVE LOOSE PARTS from the plastic bag. The combination wrench is the only tool you need. STUDY THE ILLUSTRATIONS to become familiar with the parts and their positions (FIG 8). BE CERTAIN SAW IS UNPLUGGED from power supply. SUPPORT SAW on its side with sprocket facing up. CHECK THAT THE ADJUSTER SCREW ASSEMBLY IS IN ITS SLOT. Ensure that the adjuster nut is positioned as far to the rear as possible with the lug pointing outwards ready to engage in the hole in the guide bar. (FIG. 9) Wearing gloves, mount the chain on the guide bar with the cutters facing forward on the top of the bar (FIG. 11) 7 ENSURE ADJUSTER NUT IS POSITIONED at the rear of the slot. HOLD THE CHAIN SNUGLY on the guide bar with one hand (FIG. 12). WITH THE GUIDE BAR AT A SLIGHT UPWARD ANGLE to clear the mounting bolt, enter the loop end of chain into the housing and over the sprocket. If necessary, guide the loop of chain with a finger of your other hand. SLIP THE GUIDE BAR DOWN over the mounting bolt and set it on the mounting pad. MAKE SURE THAT THE LUG ON THE ADJUSTER NUT ENTERS THE HOLE in the, guide bar. (Severe damage will result if the lug is not property located). INSTALL BAR PLATE AND WASHER on bar bolt, and secure with hex nut finger tight. STAND SAW UPRIGHT and turn adjuster screw clockwise to move bar outwards and tighten chain (FIG. 10) YOU ARE NOW READY to adjust chain tension. FIG. 9 TURN ADJUSTER SCREW CLOCKWISE TO TAKE UP CHAIN SLACK FIG. 10 CUTTERS MUST FACE IN DIRECTION OF ROTATION FIG. 11 8 ADJUST CHAIN TENSION With saw unplugged, using gloves and with the bar nut fingertightsothat bar can move: DRAW THE CHAIN along the bar rails by hand while turning the adjuster screw clockwise to increase the chain tension. Cold tension is correct when the chain side links are touching the bar rails, and the chain can be pulled along the bar without binding. (FIG. 13) TIGHTEN MOUNTING NUT with wrench to lock the bar at proper chain tension. MAINTAIN CHAIN TENSION A new chain and bar will break in and need re-adjustment after as little as five cuts. This is normal, and the interval between adjustments will lengthen quickly. Patience, to unplug the saw and adjust the chain, will result in longer life and improve cutting performance. After the break-in period, the chain will tend to droop when hot. This is normal and the chain should not be adjusted unless the drive links are close to coming out of the bar grooves (See FIG. 14). When this occurs, unplug the saw, loosen bar mounting nut, adjust tension of warm chain to a maximum droop of Va" (FIG. 15). Tighten nut. Note: Correct ch...
