| HOW TO RELEASE A BENT SPRING POLE WITH ZERO SNAPBACK |
| |

| .' \ '. NEVER cut here first |
| / \ \ |
| | SHAVE \ Pinned Tip Under Heavy Log |
| | UNDERSIDE \_______ |
| Root Base | (Compression) ( O ) <-- Heavy Fallen Trunk |
| =================|=================================================== |
| |
| STEP 1: POSITION YOUR BODY SAFELY |
| Stand to the SIDE of the sapling (ideally on the INSIDE of |
| the curve, at a 45-degree angle behind the apex), with your |
| head and chest completely out of the vertical plane of recoil. |
| |
| STEP 2: FIND THE OPTIMUM RELEASE POINT (THE 45-DEGREE BISECTOR) |
| Imagine a straight horizontal line along the pinned tip and a |
| vertical line up from the roots; bisect that 90-degree corner |
| at a 45-degree angle right through the apex of maximum bend. |
| |
| STEP 3: SHAVE THE UNDERSIDE (COMPRESSION WOOD) SLOWLY |
| Place the top of the chainsaw bar against the UNDERSIDE (inner |
| belly) of the curve at the 45-degree point. Make a series of |
| shallow, gentle shaving passes (or a narrow V-notch) across |
| the underside compression fibers. |
| |
| STEP 4: WATCH THE SAPLING FOLD GENTLY LIKE A HINGE |
| As you remove the compressed belly wood, the stretched outer |
| bark fibers on top stay intact and act as a soft strap hinge, |
| allowing the spring pole to relax and fold down smoothly with |
| zero violent snap. Once all tension is gone, sever the strap. |

| 3 SAFE ARBORIST METHODS TO BRING DOWN A HUNG-UP TREE |
| |
| METHOD 1: ROLL THE TREE OFF ITS HINGE WITH A CANT HOOK / PEAVEY |
| (Best for small-to-medium trees up to 25-30 cm / 10-12 in) |
| 1. Inspect overhead for loose dead widowmaker branches first. |
| 2. Leave a corner of hinge wood on the side you want the tree to roll |
| toward, and sever the rest of the hinge. |
| 3. Clamp a Cant Hook, Peavey, or Felling Lever onto the trunk at waist |
| height, stand on the uphill/safe side, and heave with your legs to |
| ROLL the trunk 90 to 180 degrees until its upper limbs unscrew out |
| of the supporting fork and the tree drops to the ground. |
| |
| METHOD 2: LEVER THE BUTT BACKWARD WITH A LONG WOODEN PRY POLE |
| (When the butt is resting on or just in front of the stump) |
| 1. Cut a stout green hardwood pole 3 to 4 meters (10 to 13 feet) long. |
| 2. Place a solid round log chunk on the ground 30 cm (12 in) in front |
| of the hung tree's butt as a fulcrum. |
| 3. Wedge the tip of the pry pole under the butt, stand to the side at |
| the far end of the pole, and lever the butt backward step by step. |
| |
| METHOD 3: WINCH / ROPE PULLER / TRACTOR WITH A REDIRECT PULLEY BLOCK |
| (MANDATORY for large trees > 30 cm / 12 in or tight hang-ups)|
| 1. Wrap a rated choker chain or arborist sling around the lower butt. |
| 2. Anchor a Snatch Block (redirect pulley) to a strong standing tree |
| at a 90-degree angle to the side. |
| 3. Run a wire winch cable or low-stretch bull rope through the pulley |
| to a Hand Winch (Tirfor / Maasdam), ATV winch, or Tractor located |
| at least 2x the tree's height away outside the fall zone. |

Naamne keewɗe naamneede¶
If a hung-up tree is in the middle of my woods away from houses, can I just leave it alone and let nature blow it down in the next storm?
**NO: leaving an unmarked hung-up tree standing in a woodlot is a lethal trap for children, hikers, hunters, dogs, or yourself months later.** Under **OSHA (`29 CFR 1910.266`), US Forest Service, and UK HSE (`AFAG 302`)** rules, you must bring a hung-up tree to the ground the same day using a cant hook, pry pole, or winch. If darkness is falling or you must fetch a winch, tractor, or arborist, you **MUST encircle the entire hazard zone (a radius of at least 2x the tree's height in all directions) with high-visibility DANGER flagging tape** until you return to winch it down.
Why should I never use a steel log-splitting wedge in a chainsaw felling cut to free a pinched bar?
Driving a hard **steel splitting wedge** into a chainsaw kerf while the chain is on the bar carries two major hazards: first, if the steel wedge touches the chainsaw chain, it **ruins the cutter teeth or snaps the chain**. Second, striking a steel wedge with a steel hammer or axe poll can launch **high-velocity steel shrapnel splinters** into your eyes or neck artery. Always carry two **high-impact ABS plastic or soft magnesium felling wedges (`20 to 25 cm / 8 to 10 inches` long)** in your pocket when operating a chainsaw.
What is a "Barber Chair" tree split, and how is it related to leaning trees and spring tension?
A **"Barber Chair"** occurs when a tree with a heavy **forward lean** splits **vertically up the middle of the trunk** before the felling back cut is finished: the rear half of the trunk kicks violently backward off the stump and pivots down onto the operator's head. To prevent a forward-leaning tree from barber-chairing, arborists use the **Bore-Cut (Plunge-Cut) with a Back Strap technique**: after cutting the front face notch (`70-degree open face`), bore the tip of the chainsaw bar straight through the center of the trunk behind the hinge, cut forward to set the hinge width, and then cut backward while leaving a **`3 to 5 cm (1.5 to 2 inch)` uncut holding strap at the back**, which is severed last from a safe angle.
When bucking a big uprooted windblown tree after a storm, why did the root ball suddenly slam back into the hole when I cut the trunk?
When a storm blows down a whole tree with a massive dirt-and-stone **root ball (`root plate`)** standing vertically at the base, the weight of the trunk is often the only thing counterbalancing the **3-to-10-ton root ball** from snapping back into its crater. If you sever the trunk close to an upright root plate, the **multi-ton root ball snaps 90 degrees backward into the hole like a giant mousetrap**, burying anyone in the crater while launching the cut trunk end **2 to 3 meters (6 to 10 feet) into the air**. Always **chock and brace the root plate**, never stand on the crater side, and make your first release cut far up toward the crown.
Do chainsaw protective chaps or trousers stop a battery-powered electric chainsaw the same way they stop a gasoline chainsaw?
**Standard kevlar/ballistic-nylon chainsaw chaps (`ASTM F1897 / EN ISO 11393 Class 1`) work by pulling out long fibrous threads that wrap around the drive sprocket and stall a two-stroke GASOLINE clutch.** However, many **high-torque brushless electric / battery chainsaws** have massive low-end electric torque and lack a centrifugal clutch, meaning an electric saw can cut further into standard Class 1 chaps before its overload sensor trips. Always wear **UL-certified Class 1 or Class 2 (`24 m/s`) multi-ply chainsaw chaps**, keep your left thumb wrapped around the front handlebar, and never operate any chainsaw one-handed.
