Carburetor Adjustment

A carburetor which is out of adjustment will adversely affect the performance of the engine, therefore it is important that the carburetor always be maintained in perfect adjustment.

Carburetor adjustment should only be made when the engine is at operating temperature.

  1. Adjust the stop screw so that the exhaust pressure is the same for both the right and left side. If the engine speed does not decrease when the stop screw is screwed out, loosen the lock nut and screw in the cable adjuster about one turn. The engine rpm at this point is 1,200 rpm.
  2. Starting with either the right or left carburetor, manipulate the pilot screw and find the point of highest rpm; the same should be done with the opposite carburetor. Turning the pilot screw in will give a lean fuel air mixture, turning the screw out will give a rich mixture. The pilot screw should be set at a point of one turn out from full close.
  3. After completing the adjustment in paragraph 2 above, recheck the exhaust pipe pressure on both the right and left sides and if necessary, readjust the stop screw as was done in paragraph 1.
  4. Repeat the procedure from paragraph 1 through 3 several times so that the pilot screw is set to give the optimum mixture, while the stop screws are set to provide the specified rpm and the same exhaust pressure on both the right and left sides.
  5. Next, make the adjustment so that the right and left throttle valves will both move by the same amount when the throttle grip is moved slightly. This adjustment can be made by placing your hand under the carburetor and noting the movement of the throttle lever, or by observing the movement while the throttle grip is slowly moved and checking to see that the throttle levers start moving at the same time. If adjustment is required, loosen the lock nut and perform the adjustment with the throttle cable adjuster .

How Does a Recoil Starter Work on a Lawn Mower?

The recoil starter assembly on a lawn mower allows the operator to start combustion on the mower’s engine. When the recoil starter system is engaged, the operator can crank the engine by hand and get it going fast enough to start all the internal operating systems on the mower. This starter assembly is a critical part to the mower, and without it the mower will not start.

The Starter Rope

The only visible part of the recoil starter system is the starter rope. This rope sits either on the front handle or on the mower’s engine and it allows the operator direct access to the starter system. When the operator pulls out on the starter rope, the rope engages the starting mechanism and gets the engine turning fast enough for the ignition module to generate a spark to ignite the fuel in the cylinder. This starter rope wraps around a pulley system, which allows it to be pulled out and recoil automatically into the engine.

The Pulley System

The pulley system on a lawn mower’s recoil starter usually sits below the starter cover on top of the engine. In the center of the pulley, a recoil spring connects to the pulley through a hook. When the starter rope gets pulled off the pulley and out of the engine, the recoil spring stretches out. When the operator lets go of the rope, the recoil spring snaps back and the rope recoils onto the pulley. This allows the operator to continuously pull the rope to get the engine moving faster and faster toward combustion.

The Flywheel

The recoil starter system on a lawn mower mainly serves to operate the mower’s flywheel. The flywheel sits on the starter side of the mower, on the end of the crankshaft. On the outer ring of the flywheel two magnets help generate magnetic energy as the flywheel spins around the crankshaft. When the magnets build up enough magnetic energy, they connect with the ignition module, firing off the high voltage spark required for combustion. So, as the operator pulls out on the starter rope, they are really turning the flywheel.

The Crankshaft

The crankshaft is a metal stub sitting in the center of the flywheel that powers all of the mower’s moving parts through compression. As the flywheel rotates, it also turns the crankshaft, which helps move the piston up and down inside the cylinder. This up and down pumping pulls more gas and air into the engine, and pushes out heated gases and excess fuel from the system. If the crankshaft can’t spin fast enough the entire engine will shut down, so it’s crucial to pull hard on the starter rope to get it all moving fast enough for combustion to begin.

Spindle Applications

Features:

  • Small diameter cutters offer great opportunity to benefit from HS technology.
  • Thorough evaluation of application required to determine if HS makes sense.
  • Cutter generally limits use of high speed, not spindle system.
  • HS cutting of soft materials possible but requires sufficient spindle stiffness and power.
  • Mold & Die applications benefit with superior surface finish and great quality.
  • Micro-drilling application requires high speed and accuracy, not speed alone.
  • Partner with knowledge, experience and high quality products key to success.

Our high speed spindles are used in a wide variety of applications. High speed cutting is used to improve quality, reduce cycle time, and increase manufacturing efficiency. Simply put, rotating a cutter faster will permit the cutter to perform the work faster, as long as the maximum operating limits of the cutter are not exceeded.

Any application requiring the use of a small diameter cutter can benefit from using high speed technology. Whether the need is for micro-drilling or micro-milling on a Swiss style CNC lathe, engraving on a machining center, or mold & die finishing with a small diameter ball-nose end mill, running a small cutter at higher RPM will generally save time and improve your process.

In soft materials, there are few limits to cutter speed, however, higher RPM usually requires higher spindle power. For example, machining aircraft aluminum components can benefit when using high speed cutting technology, including superior surface finish and thin walls, as long as the spindle motor has sufficient rigidity and power to support the resulting high material removal rates.

In mold and die applications, the cutter speed will be limited based on the cutter material and coatings. So, high speed is typically used for semi-finishing and finishing operations, with a very small contact area during cutting. This process results in an exceptional surface finish that minimizes or eliminates hand finishing, saving time, cost, and optimizing final part accuracy.

One very popular high speed application is micro-drilling, often required for medical and electronic component parts. A standard machine tool cannot perform this operation in a reasonable time, and often struggles to maintain acceptable quality. An high speed spindle, with exceptional accuracy (less than 1 micron runout), can perform this operation at a fraction of the time and maintain the highest quality, while also extending tool life.

To apply high speed technology to your manufacturing operation, it is critical to work with a partner that has the proven knowledge and experience to successfully advise and direct your efforts.

Square vs. Round Trimmer Line

Homeowners and professionals have an opportunity to buy many different kinds of trimmer line. These lines come in a plethora of shapes and sizes; picking the one that’s best suited for your model and your needs can get complicated. When deciding whether to use square or round trimmer line, you should always refer to your owner’s manual for size and line recommendations before making any purchases.

Square

With four sharp edges, square trimmer line cuts faster and more efficiently. The square-edged line works well if you have tall, thick and heavy patches of weeds. The downside to square line is it breaks off quicker when it contacts stones, fences, curbs and buildings. Square line also has a tendency to jam in the spool retainer if the line isn’t replaced properly.

Round

Round trimmer line is smooth and will wear down less quickly. Most cutting occurs at the very tip of the line, so when round line contacts hard surfaces, like sidewalks or trees, it will break off less. The round line is also simpler to load into the spool retainer during line replacement, which may save time in the long run if you have a lot to trim.

Star

The star or five-sided line uses this shape to make cutting even faster. Again, the same rules apply with the square model string: quicker cutting but faster wear.

Diameter

All of the lines come in a wide variety of diameters. Industry standard on most models is .080 millimetres. This diameter measures the thickness of the line. If you’re having problems with the square line breaking too quickly, you may increase the diameter size one increment. If, on the other hand, your line is jamming or fusing together inside the spool retainer, you can reduce the line size by one notch. Check with your owner’s manual for maximum line diameter; overloading can damage the driveshaft.

Considerations

Square trimmer line is quite similar to round trimmer line, and it really comes down to preference and feel. Their difference lies in the amount they will wear out. Consider how much you need to use the trimmer, over what physical conditions, how long each job will take you and how often you will need to replace your line. Both lines are relatively inexpensive, so you can experiment for the best results.

Air Filter General Use and Application

Air Filters are used and design into gas/air flow systems to remove particulates from the air flow to what is termed as “air conditioning.”

The use of filters is a simple technique of removing and preventing air born particles from clogging heating/cooling fins or radiators to as small as 0.1 micron which could cause significant performance degradation in the air flow system as well as damage the heat exchanger system.

Air filters and filtration techniques are used for a wide variety of purposes, some of which include:

  • Improving the occupants breathable environment.
  • Protecting  a facilities walls, ceiling, equipment etc. from air-born particle damage.
  • Protecting the contents of occupied building spaces such as; items of artistic historic or cultural value.
  • Elimination or minimizing fire hazards.
  • Improving shelf life of perishable food products by removing airborne mold.
  • Removing airborne bacteria from controlled environment such operating rooms.
  • Filtering or removing air born particulates which could damage sensitive micro electronic devices within clean rooms.

Installation Instructions for a Weed Eater Trimmer Line

Installing new trimmer line is a quick process that shouldn’t take you more than a few minutes.

1. Check the manual to locate the correct type of line to use in your model of trimmer. While most models use round line of varying diameters, which is sold in considerable lengths, others use shorter, precut pieces of line made to fit the specific model of trimmer, or spools preloaded with trimmer line.

2. Remove the cap of the trimmer to access the spool. While many models have one cap release latch on either side that you press to remove the cap, others require you to pull on the tap button. Still others simply require that you pull the worn line out of two sets of holes that hold it in place. Remove any remaining line when you disassemble the spool from the cap.

3. Check the manual to determine the proper length of line to wind around the spool. Most models recommend a specific length that varies between 16 and 26 feet. Weed Eater sells preloaded spools of trimmer string for models that accept them.

4. Insert the tip of the string into a guide hole and wind the remaining line around the spool in the direction indicated by an arrow on the spool, and feed the tip of the line through the outlet hole. When using the precut 24-inch lengths of trimmer line, feed the line into the two guide holes and out the side hole exits. Pull the string taut and ensure that an even length extends on each side.

5. Place the spool back into the head of the string trimmer. Replace the cap that holds the spool in place. Plug the string trimmer back into the electrical outlet or reattach the spark plug wire. Resume trimming.
