| CAUTION: Sharp moving blade. Always wear protective | |
gloves when installing or removing the chain. The chain is sharp | ||
and can cut you when it is not running. |
| |
• | Place the saw on a firm surface. |
|
| Rotate the two allen head screws |
|
| counterclockwise with the wrench |
|
| provided as shown in figure 2. |
|
• Remove sprocket cover, bar clamp, |
| |
• | and allen head screws. |
|
To remove the chain, rotate the screw |
| |
| in the front of the housing using the |
|
| flat screwdriver end of the wrench as |
|
| shown in figure 3. Turning the screw |
|
| counterclockwise allows the guide |
|
| bar to recede and reduces the |
|
| tension on the chain so that it may be |
|
• | removed. |
|
Lift the worn chain out of the groove |
| |
• | in the guide bar. |
|
Flip guide bar over. |
| |
• | To replace the chain, check to make |
|
| sure that the slot in the guide bar is |
|
| over the two location pins shown in | LOCATING PINS |
| figure 3a and that hole below the slot | |
• | is located over the adjustment pin. | ADJUSTMENT PIN |
Place new chain in groove of guide | ||
| bar and around sprocket. Make sure saw teeth are facing correct | |
| direction by matching arrow on chain with graphic on housing | |
| shown here. |
|
• Rotate the screw in the front of the housing clockwise to increase | ||
| the chain tension as in Figure 3. |
|
• Replace sprocket cover, bar clamp, and allen head screws. | ||
• Follow instructions for adjusting the chain tension. | ||
Adjusting Chain Tension |
| |
• | With the saw still on a firm surface |
|
| check the chain tension. The tension |
|
| is correct when the chain snaps back |
|
| after being pulled 1/8 in. (3mm) away |
|
| from the chain bar with light force |
|
| from the middle finger and thumb as |
|
| shown in figure 4. There should be |
|
| no “sag” between the guide bar and |
|
| the chain on the underside as shown in | 5 |
• | figure 5. | |
Toadjust saw chain tension, loosen allen |
| |
• | head screws. |
|
Rotate the screw in the front of the |
| |
| housing using the flat screwdriver end of |
|
| the wrench as shown in figure 3. |
|
• Do not | ||
| and will reduce the life of the bar and chain. Overtensioning also | |
| reduces the amount of cuts you will get per battery charge. | |
• Once chain tension is correct, tighten allen head screws to clamp bar. | ||
• When the chain is new check the tension frequently (after | ||
| disconnecting battery) during the first 2 hours of use as a new chain | |
| stretches slightly. |
|
Chain Oiling |
| |
• A high quality bar and chain oil or |
| |
| SAE30 weight motor oil should be |
|
| used for chain and bar lubrication. The | 6 |
| use of a vegetable based bar and chain | |
| oil is recommended when pruning trees. |
|
| Mineral oil is not recommended |
|
| because it may harm trees. Never use |
|
| waste oil or very thick oil. These may |
|
• | damage your chain saw. |
|
Lubricate the whole chain evenly before |
| |
| each use as shown in figure 6. Also |
|
10 | lubricate the chain whenever replacing |
|
a fully discharged battery with a fully charged one. | ||
