SAW CHAIN TENSION ADJUSTMENT
Continued
2.Turn adjusting screw clockwise until all slack is out of chain (see Figure 5). Note: There should be no gap between side links of chain and bottom of guide bar (see Figure 6).
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.
FILLING OIL TANK
1.Remove oil cap.
2.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.

Make certain you read and understand all Important Safety Information, pages 2 through 4.Improper use of this chain saw can cause severe injury or death from fire,electrical shock,or body contact with moving chain, or falling wood.
EXTENSION CORDS
Use proper extension cords with this saw. Use only extension cords marked for outdoor use. The cord must be marked with suffix W or
Use proper sized cord with this saw. Cord must be heavy enough to carry current needed. An undersized cord will cause voltage drop at saw. Saw will lose power and overheat. Follow cord size requirements listed below.

Keep cord away from cutting area. Make sure cord does not catch on branches or logs during cutting. Inspect cords often. Replace damaged cords.
The extension cord may come undone from the power cord during use. To avoid this, make a knot with the two cords as shown in Figure 7.
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.
CUTTING WITH THE CHAIN SAW
1.Connect saw to extension cord. Connect exten- sion cord to power supply.
2.Make sure section of log to be cut is not laying on ground. This will keep chain from touching ground as it cuts through log. Touching ground with moving chain will dull chain.
3.Use both hands to grip saw. Always use left hand to grip front handle and right hand to grip rear handle. Use firm grip. Thumbs and fingers must wrap around saw handles (see Figure 9).
4.Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet.
5.When ready to make a cut, press in switch lockout with right thumb and squeeze trigger (see Figure 9). This will turn saw on. Releasing trigger will turn saw off. Make sure saw is running at full speed before starting a cut.
