The numbers on an OREGON chainsaw chain are meant to provide information about the specific components of the chain. Generally, these numbers refer to the chain’s pitch, gauge, chain type, and file size.
The pitch is the distance between drive links, the gauge is the width of the drive link that fits into the guide bar groove, and the type is the shape and size of the drive links and their corresponding cutter teeth.
Pitch is usually the first number. It is followed by two numbers that represent the gauge (the first number is the whole number gauge and the second number is the decimal gauge). The third number is the chain type, which indicates the style of chain used.
Finally, the last number is the file size, which specifies the size of the round file used for sharpening the cutter tooth.
The numbers are typically located on the drive link itself. Therefore, the exact numbers will depend on the specific chain model and size of the chainsaw being used. It’s important to use the correct chain for the chainsaw size and motor power, as a wrong-sized chain can be inefficient and possibly hazardous.
What does the G mean on Oregon chain?
The “G” on an Oregon chain refers to the chain gauge, or thickness. Chains vary in thickness depending on the size of the guide bar the chain is designed for and how much power the saw requires. Oregon chains are designed to require less power, produce less noise, create a smoother cut, and last longer than standard chains.
The “G” in the chain part number typically indicates what gauge the chain is. For example, a 75LG chain indicates that it is a 0.050″ gauge, 81VXL indicates 0.043″ gauge, and 91VG indicates 0.050″ gauge.
Each gauge is specifically designed for use with certain bar sizes and engines.
How do I know my chain size in OREGON?
In order to determine the chain size in OREGON, you will need to measure the distance between three consecutive rivets on the chainsaw chain and compare that measurement against a chart that is provided by OREGON.
You will typically measure the distance between two inside rivets and one outside rivet; the measurement is then compared to the list of chain sizes provided by OREGON. To obtain an accurate measurement, it is important to use calipers or a ruler that is marked in inches.
Additionally, you should ensure that the chain is clean and straight before taking the measurement. Once the size has been determined, you can then purchase the correct size of chainsaw chain for your saw.
How do you read the specs on a chainsaw chain?
Reading the specs on a chainsaw chain involves understanding the chain type, gauge and the drive link count. The chain type refers to how thick and aggressive the chain is and will affect how well it cuts.
You’ll need to know whether the chainsaw is designed for low, standard or professional use. Typically, low-use chainsaw chains are less aggressive, less thick and have fewer drive links. Standard-use chainsaws are thicker and more aggressive and usually have more drive links.
Professional chainsaw chains are thicker still, even more aggressive and have more drive links.
The chain gauge is the thickness of the chain blade. The gauge will be a number such as 0.050 inches or 1.3 mm. A thicker gauge chain is better for longer bars and bigger cutting jobs.
The drive link count is the number of metal pieces that fit into the chainsaw’s guide bar. Typically, the higher the drive link count, the better the chainsaw will operate. A higher drive link count can also reduce the chances of kickback.
Knowing the drive link count will make it easier to buy the right replacement chain.
When reading the specs of a chainsaw chain, it’s important to note the number of teeth and the pitch. Teeth refer to the number of ridged cutting edges along the chain. Larger numbers of teeth will mean a smoother cut, but a slower cutting speed.
The pitch is the amount of space between the teeth and its unit of measurement is usually a fraction of an inch or millimeter. The combination of the number of teeth and the pitch will determine how quickly the chain will cut through wood.
By knowing the chain type, gauge, drive link count, number of teeth and pitch, you’ll be able to read the specs of a chainsaw chain accurately.
How do you use OREGON chainsaw guide?
Using an Oregon chainsaw guide is a straightforward process, but it is important to take all necessary safety precautions first, including wearing protective gloves and eye and hearing protection. Begin by selecting the size of chainsaw guide that best suits the project.
There are two types of chainsaw guides offered by Oregon – adjustable and fixed-length models. The adjustable options are more versatile, allowing you to make precise cuts between 1/4 inch to 4-1/4 inches in width.
Once the appropriate chainsaw guide is chosen and ready for attachment, make sure that the tension is adjusted properly. With the machine turned off and its chain brake activated, loosen the nut on the rear of the guide so that you can touch its lower rail without resistance.
Place the guide’s lower rail onto the chainsaw’s chain and make sure it is seated securely, then re-tighten the nut to secure it.
To use the guide, turn on the chainsaw’s power switch and activate the chain brake. When you are ready to make the cut, push down on the handle at a steady pace and follow the guide as it progresses through the material.
Be sure to keep the saw’s chain moving away from the guide, as allowing the chain to make contact with the guide may cause serious damage.
When the cut is complete, turn the chainsaw off and deactivate the chain brake. Finally, remove the guide from the chainsaw, being sure to wear the appropriate protective gear while doing so. With proper use and maintenance, you can count on the Oregon Chainsaw Guide to provide reliable service for many years to come.
What is the difference between .325 and 3/8 chain?
The difference between. 325 and 3/8 chain is the size of the chain. 325 chain is smaller than 3/8 chain, and the size is measured in the distance between the inner plates (the drive links). 325 chain has a 3/8-inch pitch between drive links, and 3/8 chain has a.
404-inch pitch between the same drive links. This larger size in the 3/8 chain gives it more strength, durability and capability to run faster than. 325 chain. Additionally, 3/8 chain can carry a greater load than.
325 chain, making it a better option for heavier applications and larger equipment.
How do I identify my OREGON chainsaw bar?
Identifying the bars of your OREGON chainsaw is relatively simple. First, take a look at the etches on the side of the bar for the OREGON logo and bar model number. If you have trouble finding it, try shining a light directly onto the side of the bar.
The logo and model number should be visible once a light is shined on the bar. If the bar is a bit worn down, then you may need to manually measure the bar size. Measure the bar length and the width of the groove at the top of the bar where the chain fits.
Have this information handy when shopping for a replacement bar or guide bar. OREGON has a wide range of sizes as well as various styles, such as narrow-kerf, semi-chisel, and full chisel, for different types and brands of chainsaw.
With this information, you should be able to easily identify the correct bar for your chainsaw.
What chainsaw pitch is best?
The best pitch of chainsaw to use depends on the project you are working on. The pitch is determined by the number of teeth per inch (TPI) on the chain. Generally, most chainsaws use a 3/8 inch pitch, meaning there are 3 teeth every 8 inches on the chain.
This is a good all-around pitch for most projects, allowing for an effective balance between cutting ability and speed.
For cutting harder woods such as oak, a. 404 inch pitch should be used for more cutting power. Those tackling big projects with extra-large trees will want to use a. 050 inch pitch for the greatest cutting ability.
For lighter material such as firewood, a. 325 inch pitch will offer faster speeds.
Ultimately, the best chainsaw pitch to use is the one that best suits the task at hand. Consider the project and use the proper pitch for the best results.
How do you identify a Stihl chain?
To identify a Stihl chain, you will need to locate the chain’s model number and size, which are located on the drive link at the end of the chain. Additionally, you will want to look for the gauge or the thickness of the drive link, the pitch of the chain, and the type of cutter the chain uses.
You can also identify Stihl chains by the needlenose shapes that you will find at the bottom of the cutters. Furthermore, the specific chain will be stamped with Stihl markings indicating it is an OEM part of the Stihl brand.
Once you have these pieces of information, you can compare them to Stihl parts catalogs or websites to accurately identify the chain.
What qualifies as traction tires in OREGON?
In Oregon, traction tires are defined as tires that have a tread depth of at least 3/16 inch when measured in any two adjacent major grooves of the tires. This includes all lugs, snow tires, and sand tires.
The tires must also either have an asserted M+S (mud and snow) designation, be of a design that is registered in the Oregon Department of Transportation’s traction tire database, or contain a pace number from the Oregon Department of Transportation’s traction tire database.
All tires must be in good condition and be capable of providing traction on snow and ice. Additionally, vehicles must carry two sets of traction tires when required in Oregon.
How do you read an Oregon chain?
Reading an Oregon chain involves identifying the chain pattern and size, and then measuring the chain on a ruler or measuring tape. To identify the chain pattern, look for alternating small and large teeth.
To measure the chain size, determine the two most extreme distances between the teeth, then measure each side from the inside and outside edges with a ruler or measuring tape.
Once you have your measurements, you will need to determine the chain pitch and chain gauge. The chain pitch is the distance between three successive rivets divided by two, and the chain gauge is the thickness of the bar.
Generally, Oregon chain is either. 325 or. 375 pitches and. 063 or. 058 gauges. A. 325 pitch chain with. 063 gauge is more common for saws, while. 375 pitch with. 058 gauge is more common for electric chainsaws and pole saws.
Once you have identified the Oregon chain pattern and size, you will need to find a replacement chain that matches these specifications. Check the owner’s manual to ensure the replacement chain is compatible with your saw or chainsaw, and follow the manufacturer’s instructions to install the chain.
Can I use Oregon chain on a Stihl chainsaw?
Yes, you can use an Oregon chain on a Stihl chainsaw. In fact, Stihl and Oregon both make high-quality replacement chains that are designed to fit all major brands of chainsaw models. Oregon replacement chains feature their patented chain designs, like their low-vibration, low-kickback X-Cut technology, and their unique Micro-Chisel design for improved performance.
In addition, these chains come in a variety of sizes and styles, making them an ideal solution for all types of saws. Regardless of the brand of your chainsaw, you can trust that Oregon replacement chains will fit securely and provide superior performance.
What size file do you use on a 3/8 chain?
Most chainsaw manufacturers recommend using a 3/8-inch-pitch chain, which corresponds to a 3/8-inch-type chain file. The size of the file varies depending on the type of chain and the depth of the teeth.
For instance, a. 325-inch chain file will work for a 3/8-inch-pitch chainsaw chain with a. 325-inch grove size. For a 3/8-inch-pitch chain with a. 404-inch grove size, then a. 404-inch chain file is the best fit.
To determine the specific size your chain requires, you should refer to the manufacturer’s owner’s manual or the specific chain that you have. When choosing a chain file, it is important to buy one that is designed for chainsaw use as it will have the right shape and teeth in order to work properly with your chain.
