Worx WG307 chainsaw Parts

An Oregon chain can fit a Worx WG307 only if it matches the exact chain specs your saw requires (pitch, gauge, and drive link count). For safety and proper oiling, we follow the WG307 requirements listed in the WG307 owner's manual and match any Oregon chain to those specs.

How to confirm fit (what to match)

Check these three items before buying any replacement chain:

• Pitch (spacing of the chain links)
• Gauge (drive link thickness)
• Drive link count (number of drive links)
• Bar length compatibility (chain must match the guide bar)
• Intended use (pruning vs. heavier cutting)

If any one of these does not match, the chain will not track correctly on the guide bar and can cut poorly or bind.

Why we recommend sticking to the manual

Your Worx saw documentation emphasizes safe handling and correct chain setup, including checking chain tension and using the specified replacement bar and chain. A chain that is slightly off-spec can:

• Increase kickback risk
• Wear the guide bar and drive sprocket faster
• Reduce cutting speed and cause rough cuts
• Interfere with the automatic oiler (chain and bar can run dry)

For safe operation practices, we also recommend reviewing how to prevent chainsaw injuries.

Quick compatibility checklist

Use this table as a final double-check before you purchase an Oregon chain.

What you’re checking	Where to find it	What must match
Pitch	Bar stamp or manual	Exact value
Gauge	Bar stamp or manual	Exact value
Drive links	Old chain count or packaging	Exact count
Bar type	Existing guide bar	Must be compatible

After installing any chain: must-do steps

Once you install a replacement chain on the WG307, do these checks before cutting:

• Unplug the saw before adjustments
• Set correct chain tension (snug, but still moves freely)
• Confirm cutting teeth face the correct direction
• Fill the oil tank with bar and chain oil
• Verify a slight oil presence on the chain and bar during use

Why it matters

A correctly matched chain protects the motor, guide bar, and oiler system, and it keeps cutting performance consistent. The right chain fit is also one of the biggest factors in safe, predictable cutting.

Yes. Worx electric chainsaws like the WG307 are a solid choice for typical homeowner cutting and pruning because they are simple to operate, require less routine engine maintenance than gas saws, and are designed for consumer use. For safe, consistent performance, follow the operating and maintenance steps in the WG307 owner's manual.

What the WG307 is best for

The WG307 is built around homeowner tasks where control and basic upkeep matter most.

• Pruning branches and cutting small logs
• Light yard cleanup after storms
• Occasional trimming where quick setup is important
• Users who prefer corded electric power over fuel mixing
• Owners who want straightforward chain lubrication and tension checks

What “good” depends on (quick checklist)

A chainsaw feels “good” when it cuts efficiently and stays safe and predictable.

What you care about	What to look for	Why it matters
Cutting performance	Sharp chain, correct chain tension	Faster cuts, less motor strain
Reliability	Intact power cord, smooth handle action	Prevents sudden stoppages and unsafe operation
Ease of ownership	Simple lubrication routine	Reduces wear on the guide bar and chain
Safety	Working trigger lockout, proper technique	Lowers kickback and injury risk

Maintenance that makes a Worx electric chainsaw perform well

From the WG307 manual guidance, consistent lubrication and basic inspections are key.

• Fill the oil tank with bar and chain oil before use; never run with an empty tank.
• Check the oil level window and confirm a slight oil presence on the chain and guide bar during operation.
• If the chain and bar look dry, clear the bar oil hole and recheck oiling.
• Inspect before and after each use for cord damage, proper chain tension, and adequate lubrication.
• Unplug the saw when not in use, before cleaning, and before changing accessories.

Why it matters

Most “bad chainsaw” complaints come from setup and upkeep issues (dull chain, loose chain, or poor lubrication), not the brand. Keeping the chain sharp, properly tensioned, and lubricated helps the WG307 cut better and reduces overload on the motor.

For the Worx WG307 electric chainsaw, we use bar and chain oil (chain oil) in the oiler tank. The manual specifies that bar and chain oil of any brand can be used, and the saw should never be operated with an empty oil tank. See the WG307 owner's manual for the fill procedure and oiling checks.

What oil to use (and what to avoid)

Use the same type of lubricant you would use on a gas chainsaw bar and chain.

• Use bar and chain oil (also called chain oil)
• Use new, clean oil only
• Do not use recycled or old oil
• Do not run the saw with an empty oil tank
• If you are unsure at the store, look for bottles labeled bar and chain oil

Quick fill and check steps

Follow the safety steps in the manual; the key points are:

1. Unplug the tool before filling.
2. Open the oil filler flap and fill the reservoir with bar and chain oil.
3. Close the filler flap securely.
4. During use, check the oil level window and refill as needed.
5. Periodically inspect the bar and chain; a slight oil presence should be visible.

Automatic oiler check: what “normal” looks like

The manual notes this saw uses a lower chain speed than a conventional chainsaw, so it uses less oil, but it still must always have oil.

What you see	What it usually means	What to do
Light oil film on bar/chain	Oiler is working	Keep cutting; recheck level periodically
Bar/chain look completely dry	Oil not reaching the bar	Clean/check the bar oil hole; confirm tank has oil
Oil seems to pump out when not cutting	Handle is being pushed repeatedly	Avoid pumping the handle when not cutting

Why it matters

Correct chain lubrication reduces friction and heat, helps the chain cut smoothly, and prevents motor overload and premature wear of the bar and chain.

Yes. Worx makes chainsaws, including the Worx WG307 electric chainsaw, which is designed for consumer cutting tasks like pruning branches and cutting small logs (typically up to about 4 inches in diameter). For model-specific operation and safety details, use the WG307 owner's manual.

What the WG307 is designed to do

Worx positions this model for light-duty, homeowner use where control and safety are priorities.

• Prune branches and trim limbs
• Crosscut small logs for cleanup work
• Use a guide bar and saw chain with an automatic oiler system
• Run on electric power (unplug before adjustments or maintenance)
• Support safer handling with proper PPE (eye, hearing, and hand protection)

Key operating and safety basics (quick checklist)

These are the most important habits we recommend for the WG307 before you cut.

• Keep the chain properly tensioned; re-tension if you see a gap between chain and guide bar
• Keep the chain sharp, clean, and lubricated
• Fill the oil tank with bar and chain oil before use; never run with an empty tank
• Periodically confirm oil is reaching the chain and bar during operation
• Unplug the saw before touching the chain, adjusting tension, or filling oil

Common “chainsaw” terms you will see in the manual

Term	What it means	Why it matters
Guide bar	The bar that supports and guides the chain	A worn bar can make cutting harder and damage the chain
Drive sprocket	Toothed part that drives the chain	Often replaced with the chain to maintain proper drive
Automatic oiler	System that oils the bar and chain	Prevents poor cutting performance and motor overload

Why it matters

Choosing the right chainsaw type helps you cut more safely and avoid premature wear. With an electric model like the WG307, chain tension and lubrication are the two biggest day-to-day factors that affect cutting performance and motor load.

If your Worx WG307 electric chainsaw runs but won’t cut, the most common causes are incorrect chain tension, a dull chain, the chain installed backward, or lack of bar-and-chain oil. Correcting tension and lubrication usually restores normal cutting performance.

Quick checks (do these first)

• Unplug the saw before inspecting the chain, bar, or sprocket.
• Confirm the chain is installed in the correct direction (a backward chain will not cut).
• Check chain tension; a chain that is too tight can bind and stop cutting.
• Check the oil level window and refill with bar-and-chain oil; running dry causes poor cutting and motor overload.
• Look for oil on the chain and bar during operation; they should not appear completely dry.
• Clear debris from the chain access area and bar oil hole.

Chain tension and chain direction

Chain tension that is set incorrectly can cause poor cut quality or a saw that “runs but does not cut.” Set tension so the chain moves freely by hand (with gloves) but stays seated on the guide bar.

Symptom	What it usually means	What to do
Motor runs, little or no cutting	Chain installed backward	Reinstall chain in correct direction
Chain won’t rotate freely	Chain too tight	Reduce tension per the manual
Cuts slowly, makes fine sawdust	Chain is dull	Sharpen or replace chain

For the exact adjustment method for the WG307, follow the WG307 owner's manual.

Lubrication problems that stop cutting

The WG307 must have bar-and-chain oil in the tank. If the chain and bar look dry during use, remove the bar and chain and make sure the bar oil hole is not blocked. Operating without oil leads to poor cutting performance and can overload the motor.

Why it matters

A properly tensioned, correctly installed, well-lubricated sharp chain cuts faster and safer, and it reduces wear on the sprocket, guide bar, chain, and motor.
