Checking the Oil Level and Adding Bar and Chain Oil
Maintenance Service Interval | Maintenance Procedure |
---|---|
Before each use or daily |
|
After each battery drain cycle |
|
Important: Use only bar and chain oil (sold separately).
-
Shut off the chain saw and remove the battery pack; refer to Removing the Battery Pack.
-
Check the oil level in the window. If the oil does not fill the window, add bar and chain oil as needed (Figure 26).
-
Place the chain saw on a flat surface with the oil cap facing up.
-
Clean the area around the oil cap (Figure 26).
Note: Ensure that you do not allow debris/wood chips to enter the oil tank.
-
Unfold the wing-nut tab on the oil cap tab, remove the cap, and pour bar and chain oil into the chain saw until the oil fills the tank (Figure 26).
Important: Do not fill the chain saw higher than the bottom of the fill neck.
-
Clean up any spilled oil, secure the oil cap, and fold the wing-nut tab down.
-
Ensure that oil is flowing to the chain; refer to Checking the Flow of Bar and Chain Oil.
Checking the Chain Brake
Maintenance Service Interval | Maintenance Procedure |
---|---|
Before each use or daily |
|
After each battery drain cycle |
|
-
Engage the chain brake by moving the chain brake forward to the STOP position (Figure 27).
-
Prepare to test the chain saw operation; refer to Before Using the Chain Saw.
-
Attempt to start the chain saw. If it starts, take the chain saw to an Authorized Service Dealer for repair.
-
Disengage the chain brake by moving the chain brake rearward to the OPERATING position (Figure 27).
Checking the Flow of Bar and Chain Oil
Maintenance Service Interval | Maintenance Procedure |
---|---|
Before each use or daily |
|
-
Prepare to use the chain saw; refer to Before Using the Chain Saw.
-
To ensure that oil is flowing to the chain, point the nose of the chain saw a few inches from a surface (e.g. paper, cardboard, a stump) and run the chain saw; you should be able to see a light spray of oil on the surface (Figure 28).
-
If oil is not flowing, ensure that there is oil in the tank and that the area under the side cover is clean; refer to Checking the Oil Level and Adding Bar and Chain Oil and Servicing the Guide Bar, Chain, and Drive Sprocket.

Adjusting the Chain Tension
Maintenance Service Interval | Maintenance Procedure |
---|---|
Before each use or daily |
|
After each battery drain cycle |
|
Ensure that the chain is properly tensioned.
A loose chain shortens the life of the drive sprocket and the guide bar and may cause the chain to fall off.
An overtightened chain overheats the guide bar and chain, causing rapid wear, and may burn out the motor or break the chain.
The chain tension is correct when you are able to use a gloved hand to pull the chain smoothly around the guide bar. The chain should remain in contact with the bottom edge of the guide bar.
Also, check the chain tension of a new chain after a few cuts; a new chain usually stretches and requires adjustment after a few cuts.
Danger
Contact with the chain saw teeth can cause serious personal injury.
-
Remove the battery pack before adjusting or maintaining the chain saw.
-
Always wear gloves when adjusting or maintaining the chain saw.
-
Place the chain saw on a level surface and remove the battery pack; refer to Removing the Battery Pack.
-
Allow the saw chain to cool.
Important: Do not tension a hot chain; it may contract as it cools, resulting in an overtightened chain.
-
Inspect the guide bar for bends or damage, replace if necessary.
-
Ensure that the chain brake is in the OPERATING position (Figure 27).
-
Using the onboard multitool, loosen the captive nuts on the side cover, but do not remove it (Figure 30).
-
Hold up the tip of the guide bar (Figure 29).
-
Using the onboard multitool, adjust the chain tension, and then secure the side cover to the chain saw by tightening the captive nuts (Figure 30).
-
To tighten the chain, turn the chain tensioning screw clockwise (Figure 29).
-
To loosen the chain, turn the chain tensioning screw counterclockwise
Adjust the chain tension until the chain touches the bottom edge of the guide bar, then pull the chain away from the bottom edge of the guide bar; a properly adjusted chain can only be pulled 3.2 to 6.4 mm (1/8 to 1/4 inch) away from the guide bar, and snaps back on release.
If the chain is not properly tensioned, loosen the side cover and repeat steps 5 through 8.
-
-
Use a gloved hand to pull the chain around the guide bar. A properly tensioned chain should move smoothly and remain in contact with the bottom edge of the guide bar.
-
Check the chain tension again and repeat this procedure if necessary.

Servicing the Guide Bar, Chain, and Drive Sprocket
Maintenance Service Interval | Maintenance Procedure |
---|---|
Before each use or daily |
|
Yearly or before storage |
|
Danger
Contact with the chain saw teeth can cause serious personal injury.
-
Remove the battery pack before adjusting or maintaining the chain saw.
-
Always wear gloves when adjusting or maintaining the chain saw.
-
Place the chain saw on a flat surface and remove the battery pack; refer to Removing the Battery Pack.
-
Remove the side cover by loosening the 2 captive nuts that secure the cover (Figure 30).
Note: The captive nuts do not separate from the side cover; loosen them until the cover can be removed.
-
Loosen the chain by turning the chain-tightening screw counterclockwise (Figure 30).
-
Separate the chain from the guide bar and set them aside.
-
Remove the clip and drive sprocket from the chain saw (Figure 31).
-
Clean any debris from the area under the side cover.
-
Inspect the drive sprocket; if it is excessively worn or damaged, replace it.
-
Install the drive sprocket and clip.
-
Check the oil outlet (Figure 31) for debris and clean the area if necessary.
-
Clean the guide bar and chain; use a wire or a small flat-head screwdriver to remove dirt and debris from the groove along the edge of the guide bar, starting from the sprocket on the front end and moving rearward.
Ensure that the oil channel in the bar that aligns with the oil outlet on the chain saw is clean so that oil can flow freely to the chain (Figure 32).
-
Inspect the guide bar and chain; if the bar is bent, the grooves are damaged, or if the sprocket on the front end does not rotate freely, replace the guide bar; if the chain is excessively worn or damaged, replace it.
-
Install the guide bar and chain; refer to Installing the Guide Bar and Chain.
-
Ensure that oil is flowing to the chain; refer to Checking the Flow of Bar and Chain Oil.
Installing the Guide Bar and Chain
Danger
Contact with the chain saw teeth can cause serious personal injury.
-
Remove the battery pack before adjusting or maintaining the chain saw.
-
Always wear gloves when adjusting or maintaining the chain saw.
-
If the side cover is installed to the machine, loosen the 2 captive nuts securing the side cover to the machine and remove it (Figure 33A and Figure 33B).
-
Place the chain around the drive sprocket on the front end of the guide bar, with the cutting edge of the chain teeth on the top of the bar facing forward as shown in the diagram on the side cover of the chain saw (Figure 33C).
-
Feed the chain around the guide bar and align the chain into the groove of the guide bar.
Note: If you are installing a new chain, flip the guide bar to avoid uneven wear.
-
Position the open loop of the chain (not on the guide bar) around the drive sprocket on the chain saw and install the guide bar and attached chain onto the chain saw as shown in Figure 33C.
Important: Ensure that the chain adjusting stud is inserted into the hole indicated by the arrow in Figure 33C. You may need to rotate the chain tensioning knob to fit the stud into the hole in the guide bar.
-
Install the side cover, but do not fully tighten the captive nuts (Figure 33D).
-
Adjust the chain tension; refer to Adjusting the Chain Tension.

Sharpening the Chain
Maintenance Service Interval | Maintenance Procedure |
---|---|
Before each use or daily |
|
Yearly or before storage |
|
A sharp chain ensures better cutting performance and longer battery life.
The chain needs to be sharpened or replaced if you must force it onto the wood, or if it produces sawdust instead of full wood chips.
Contact an Authorized Service Dealer to have the chain sharpened or replaced.
Service
Should the chain saw need service, take the tool to your Authorized Service Dealer.
