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. | 2 |
• 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 | 3 |
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. | 3a |
• To replace the chain, check to make | |
sure that the slot in the guide bar is |
|
over the two location pins shown in |
|
figure 3a and that hole below the slot | Locating Pins |
is located over the adjustment pin. | |
• Place new chain in groove of guide | Adjustment Pin |
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 | 4 |
|
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. |
| |
• To adjust 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 |
| 6 |
used for chain and bar lubrication. |
| |
The 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 |
|
|
lubricate the chain whenever replacing a |
| |
fully discharged battery with a fully charged one. | ||
