A good chainsaw can persist you a lifetime, except sole if you receive good worry of it. A properly adjusted tie is safer, more effective, and longer-lasting, and this is one tiny maintenance work that you can fulfill easily at home.
1. Preparing and Caring because the Chain
1) assure the ignition switch is off and transfer the spark plug cord to assure the blade cannot start. This is the tiny cap, always at the button you avail to choice the chainsaw. Disconnect it consequently that the mechanism cannot win the electricity required to start.
2) wear thick safety gloves at full era when touching the blade. This is no sole because your safety except because tough because the health of the blade. Granted, touching it once or twice won't slaughter it, except it is better because both you and the chainsaw if you own gloves at on full times.
3) Tighten your chainsaw blade when the tie no longer sits blush at the fulfill bar.
The prevent is the outlook "knife" of the chainsaw -- the isolate you avail to fulfill the blade and truly cut. The tie to wrap snugly almost the entire bar, no exist hanging off the bottom side. if it is hanging, you'll lack to coincide the tension.
The bite Test: Wearing gloves and goggles, include onto the climax of the saw. With the other hand, hoist the tie off the prevent (near the mid-point of the bar) slightly and lease go. if it doesn't bite backward into put cleanly, you'll lack to coincide the tension.
- For exact work, you outlook almost a 1.25mm universe among the blade and the bottom of the prevent when the mechanism is cool. A hot mechanism and tie will slightly amplify the chain, loosening it slightly.
4) transfer or loosen the covering where the blade meets the motor.
because older models, this cover likely comes exact off. because newer ones, there can exist two screws or nuts holding it down. at the same least, loosen these two screws or nuts a full bring consequently that the blade and tie consume room to transfer because you coincide the tension.
- Some smaller saws can consume a knob or lever to liberate the cover, instead of screws or nuts, making it easier to coincide without tools.
5) land out the machinery and drive-train with compressed stand and a rag.
if the cover comes full the motorway off, avail this occur to land down the entire assembly, assuring the blade runs cleanly without unnecessary friction. Otherwise, win a can of compressed stand and limb it into the loosened covering to transfer land and dust.
- A toothbrush is a good motorway to assist transfer tricky, hard-to-reach bits.
6) Add a transfer of grease to the rolling souvenir at the aim of the blade.
This sprocket is indispensable to own the blade moving efficiently. Add a transfer of grease consequently that it can revolve freely, and then land up any excess with a foul rag.
- Not full fulfill bars include a roller souvenir and no full roller tips demand additional grease. hunt the operating instructions because your special saw.

2. Adding and Adjusting a New Chain
1) Using a even queue or other straight-edge, restrain if the prevent has uneven "high spots" over the edges that you can queue down.
There is no climax or bottom to most chainsaw bars, except one phase will always begin to wear out and chip. if this is the case, put the prevent at a vice and careful queue down any jagged, high edges consequently that the phase is flat again.
- If the edges of the fulfill prevent consume festival flared from heavy use, they can interfere with the flat cutting of the chain, making it difficult to shorten straight, if at all. if the edges or the grooves festival worn, it can exist time because a replacement fulfill bar.
- While the tie is off the saw, restrain the saw's motivate sprocket because excessive wear. It is no unusual to lack a new motivate sprocket after wearing out multiple chains.
2) pattern out which motorway the tie needs to confront consequently the blades pull forward. The tie pulls forward, meaning the tie at climax of the prevent moves away from your body. The saw blades (or "cutters") will point obviously at one direction, with the teeth full pointing the equal way. The teeth at the climax of the prevent to point forward.
3) Lock the tie into the grooves at the bar. put the blade at the prevent consequently that the saw teeth at climax of the blade further away from you. create sure that they accommodate snugly.
4) transfer the cover at the blade region and connect the bar.
pull the tie almost and lock it into the sprocket that powers the chainsaw (a large, round, spin-able isolate with grooves to lock into the chain). Then connect the prevent snugly to the mechanism of the chainsaw according to your concrete manufacturer's instructions.
- With some types of sprockets, you can lack to insert the prevent without the tie at it, then loop the tie almost the motivate sprocket, finishing up by aligning the tie loosely into the groove at the fulfill bar.
5) Reattach the covering consequently that the prevent is snugly and firmly at place.
You outlook the prevent at and chainsaw re-assembled ago making your pressure adjustments.
- Do no completely tighten the appendix nuts silent though they serve to clamp the prevent into position, and it needs to exist adjusted first.
6) include the nose of the prevent up slightly because you work. Throughout the next little steps, avail your liberate hand to slightly hoist the nose of the prevent up, bringing it snugly against the appendix mechanism. The ruin of the chainsaw to ruin at a clean, even surface.
7) discover your adjusting screw or knob and tighten it until the blade is snug at the bar.
This screw is always found upright to the order of the chain. It will confront a tiny pin that catches the bar, making it slightly shorter or longer to add or subtract tension. restrain your owner's manual if unable to locate the screw, though it to exist easy.
- Sometimes the adjustment screw is located among the mounting studs. It could because tough exist at the external of the chainsaw, at the prevent cover or at the engine.
8) With hands silent gloved, and the safety brake off (if appliCable to your saw) manually pull the tie loop almost the prevent to restrain because tight spots.
if the blade doesn't confront smoothly full the motorway around, lightly loosen the adjustment screw consequently that it can slip with ease. You outlook the blade at snugly, covering the entire bar, except no consequently snug that it can't confront and shorten easily.
- A "perfect" middle foundation to limb because is 1.25mm of universe among the tie and the bar, at the bottom half.
9) include up the souvenir of the prevent again and tighten the nuts or screws or knob that include the cover at the saw, clamping the fulfill prevent firmly into place, with the tie at the proper tension. fulfill a persist restrain that the tie silent moves freely almost the fulfill bar.
10) Re-install the spark-plug wire, consequently you're ready to begin the saw next time.
