On the Craftsman gas chainsaw model 316380180, the model number is printed on the product identification label (often called the rating tag). We typically see that label on the engine housing or main saw body, where it stays readable but protected.

Most common places to check

Look for a sticker or metal tag on these areas:

• Side of the engine/motor housing near the starter cover
• Rear handle area (back side of the saw body)
• Bottom of the saw body near the fuel and oil tanks
• Under or near the air filter cover
• Near the bar mounting area (clutch cover side)

For diagrams and model identification details specific to this saw, use the 316380180 operator’s manual.

What the label usually looks like

The tag normally includes the model number and other identifiers. Here is what to expect:

Item on label	What it’s used for	Example for this saw
Model number	Matching parts and instructions	316380180
Product type	Confirms equipment family	2-cycle gas chainsaw
Manual/series info	Helps match documentation	Operator’s manual reference

Tips to find it faster

These steps help you locate the label without missing it:

• Wipe dust and oil off the housing with a rag so the print is readable
• Use a flashlight and check recessed areas around covers and handles
• Rotate the saw and inspect both sides, not just the pull-start side
• Write the number down exactly as shown (all digits matter)

Why it matters

The correct model number ensures you get the right Craftsman parts (like a guide bar, chain, fuel filter, or carburetor) and the correct maintenance instructions for chain tensioning, bar and chain oil, and safe operation.

For the Craftsman 316380180 gas chainsaw, we use fresh unleaded gasoline mixed with 2-cycle engine oil at a 40:1 fuel-to-oil ratio. This model is a 2-cycle saw, so it does not use straight gas in the fuel tank; the oil must be mixed into the fuel.

Fuel mix you should use

• Use fresh unleaded gasoline (do not use old or stale fuel).
• Mix with 2-cycle engine oil at 40:1.
• Mix fuel in an approved fuel container, then fill the saw.
• Use bar and chain oil in the chain oil reservoir (separate from the fuel).

Quick mix chart (40:1)

Gasoline amount	2-cycle oil to add	Notes
1 gallon	3.2 fl oz	Common pre-measured bottle size
1/2 gallon	1.6 fl oz	Good for small batches
1 liter	25 mL	Handy metric reference

Don’t confuse fuel oil with bar and chain oil

This chainsaw uses two different oils:

• 2-cycle oil: mixed into the gasoline (engine lubrication)
• Bar and chain oil: goes in the oil reservoir (lubricates the bar and chain)

For capacities on the Craftsman 316380180, we follow the specs in the 316380180 operator’s manual.

Why it matters

Using the correct 40:1 mix helps the engine start easier, run cooler, and avoid premature wear. Straight gas (no 2-cycle oil) can damage a 2-cycle engine quickly, while too much oil can cause heavy smoke and poor performance.

A 42cc chainsaw does not have one fixed horsepower rating; horsepower varies by engine design and tuning. For the Craftsman model 316380180, the 316380180 owner's manual lists the engine displacement (42 cc) and other specs, but it does not publish a horsepower number.

What you can use instead (model 316380180)

These specs from the manual are the best way to compare real-world cutting capability:

• Engine type: air-cooled, 2-cycle
• Displacement: 42 cc (2.56 cu. in.)
• Guide bar length: 18 in.
• Fuel/oil mix ratio: 40:1
• Approximate dry weight: 14 to 15 lb

Spec	What it tells you	Why it matters
42 cc displacement	Engine size	Larger cc usually supports more torque under load
18 in. guide bar	Typical cutting capacity	Helps match the saw to limb and log diameter
14 to 15 lb (dry)	Handling and fatigue	Heavier saws can cut well but tire you faster

Typical horsepower range for 42cc saws

Most 42cc consumer 2-cycle chainsaws are commonly marketed around 2 to 3 HP. Use that as a general expectation, then rely on bar length, chain type, and condition to judge performance.

Why it matters

Horsepower is not measured or reported consistently across chainsaw brands, so it is easy to compare numbers that were calculated differently. For day-to-day use, a sharp chain, correct chain tension, and a clean air filter often make a bigger difference than a published HP figure.

Quick performance checks (no special tools)

• If cutting feels slow, inspect and clean or replace the air filter 753-08134.
• Confirm you are using the correct 40:1 fuel mix.
• Make sure bar and chain oil is flowing and the oil reservoir is filled.
• Verify the chain brake is fully released before cutting.

For the Craftsman gas chainsaw model 316380180, 40:1 is the better choice because it is the specified fuel/oil ratio for this saw. Mixing at 50:1 reduces oil content and can increase wear and overheating risk on a saw designed for 40:1; use the ratio listed in the 316380180 operator’s manual.

What to use for model 316380180

Use a 40:1 fuel-to-2-cycle-oil mix (that is 40 parts gasoline to 1 part 2-cycle oil). This matches the model’s specification and supports proper lubrication under load.

Quick mix chart (40:1)

Gasoline amount	2-cycle oil needed (40:1)
1 gallon	3.2 fl oz
2 gallons	6.4 fl oz
5 gallons	16 fl oz

Why 40:1 vs 50:1 matters

The ratio controls engine lubrication in a 2-cycle chainsaw. Too little oil (lean oil mix) can accelerate piston and cylinder wear; too much oil can increase smoke and carbon deposits.

Common symptoms of the wrong mix

• Hard starting or poor idle
• Loss of power under load
• Excessive smoke (often too much oil)
• Spark plug fouling
• Hot running or scoring risk (often too little oil)

Tips for best results

• Use fresh gasoline and a quality 2-cycle oil intended for air-cooled engines.
• Mix in an approved fuel container; add half the gas, add oil, shake, then top off and shake again.
• Do not store mixed fuel long-term; make only what you will use soon.
• If performance drops, check maintenance items like the air filter 753-08134 and fuel filter condition.
