See Saw Chain Tension Adjustment. WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain. IMPORTANT: Do not clamp chain saw in vise during assembly. The plastic hardware bag should include: • two guide bar bolts • two guide bar nuts • one Phillips-head tapping screw 1. Lay chain out flat. 2. Install front hand guard onto saw body. Do this by pressing two mounting stand-outs on hand guard into hex-shaped holes in saw body (see Figure 2). Insert tapping screw through hand guard and into saw handle. Tighten screw firmly. 4. Turn adjusting screw counterclockwise (see Figure 3). Continue to turn adjusting screw until adjusting block is to rear of adjusting plate. 5. Install guide bar onto saw body. Place rear of guide bar between adjusting plate and sprocket support. IMPORTANT: Make sure to insert adjusting block into oval adjusting hole on guide bar. 6. Line up holes on sprocket support with center slot on guide bar and holes in saw body. 7. Insert guide bar bolts through front hand guard, saw body, center slot of guide bar, and sprocket support. Attach guide bar nuts to guide bar bolts. IMPORTANT: Tighten guide bar nuts finger tight only. Make sure adjusting block is in oval adjusting hole on guide bar. 8. Place chain around drive sprocket, then along top groove of guide bar and around guide bar nose. Note: Make sure cutting edges of chain are facing the right direction. Position chain so cutting edges on top of guide bar face guide bar nose (see Figure 3). 9. Adjust saw chain tension. Follow steps under Saw Chain Tension Adjustment. CAUTION: Do not place chain on saw backwards. If chain is backwards, saw will vibrate badly and will not cut.

A new chain will stretch. Check new chain after fi rst few minutes of operation. Allow chain to cool down. Follow steps below to readjust saw chain tension. 1. Before adjusting chain, make sure guide bar nuts are only finger tight (see Figure 2, page 8). Also make sure adjusting block is in oval adjusting hole on guide bar (see Figures 2 and 3, page 8). 2. Turn adjusting screw clockwise until all slack is out of chain (see Figure 4). Note: There should be no gap between side links of chain and bottom of guide bar (see Figure 5). 3. Wearing protective gloves, move chain around guide bar. Chain should move freely. If chain does not move freely, loosen chain by turning adjusting screw counterclockwise. 4. After chain tension is correct, tighten guide bar nuts firmly. If not, guide bar will move and loosen chain tension. This will increase the risk of kickback. This can also damage saw. Note: A new chain will stretch. Check new chain after first few minutes of operation. Allow chain to cool down. Readjust chain tension. SAW CHAIN TENSION ADJUSTMENT WARNING: Unplug chain saw from power source before adjusting saw chain tension. WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain. WARNING: Maintain proper chain tension always. A loose chain will increase the risk of kickback. A loose chain may jump out of guide bar groove. This may injure operator and damage chain. A loose chain will cause chain, guide bar, and sprocket to wear rapidly.

Fill oil tank with SAE #30 motor oil. Note: For temperatures below 30°F, use SAE #10 oil. For temperatures above 75°F, use SAE #40 oil. 3. Replace oil cap at once. Tighten oil cap firmly for good seal. This will avoid oil seepage from tank. 4. Wipe off excess oil. Note: It is normal for oil to seep when saw is not in use. Empty oil tank after each use to prevent seepage. WARNING: Read and understand this owner’s manual before operating this saw. Make certain you read and understand all Important Safety Information. Improper use of this chain saw can cause severe injury or death fromfire, electrical shock, or body contact with moving chain, or falling wood. OILING CHAIN Always check oil level before using saw. Do not attempt to operate the oil system while saw is in operation. To oil chain, press squeeze bulb. Oil will feed onto the guide bar and chain. Press squeeze bulb at least once before each cut. Check oil level often by looking at oil sight level hole. Oil sight level hole is on left side of saw, between front handle and front hand guard.
