  • Safety: Loose or misaligned blades can be dangerous. Proper adjustment avoids injury.
  • Longevity: Keeping hedge shears adjusted maximizes their working life. This saves money and hassle.

How to Tell if Fiskars Hedge Shears Need Adjusting

With regular use, Fiskars hedge shears can get knocked out of proper alignment. Here are signs it’s time to adjust them:

  • The blades don’t line up correctly at the tips. There should be no gap between top and bottom blades.
  • Cutting requires extra effort or feels awkward. Properly aligned shears cut smoothly.
  • The blades crush or tear branches rather than cutting neatly.
  • The blades exhibit side-to-side looseness or wiggle.
  • The locking mechanism doesn’t hold the blades closed.
  • The lower blade doesn’t sit parallel to the upper blade.
  • The blades don’t cut all the way to the tip.

Any of these issues indicate it’s time to tune up Fiskars hedge shears with adjustments. Catching problems early makes correction easier.

How to Adjust Fiskars Hedge Shears – Adjusting Standard Manual Fiskars Hedge Shears

Fiskars manual hedge shears are simple but effective tools. With basic care, they’ll stay that way for years. Here’s how to adjust standard manual Fiskars hedge shears:

Step 1: Clean the Blades

  • Remove any debris, sap, or dirt buildup. Use a wire brush and wipe down with a clean rag.
  • Check for sticky residue. Remove it with mild dish soap and water.
  • Dry the blades thoroughly before adjusting or using.

Step 2: Align the Blades

  • Examine blade alignment. The cutting edges should meet precisely tip-to-base when closed.
  • If there’s a gap at the tip, use an Allen wrench to loosen the screw behind the pivot point.
  • Carefully realign the blades until their edges match up.
  • Tighten the screw just enough to hold the setting. Don’t overtighten.

Step 3: Set Proper Blade Tension

  • Test the blade tension by making test cuts in soft wood or thick stems.
  • If blades don’t close tightly, increase tension: Use an Allen wrench to tighten the tension screw clockwise. Make adjustments gradually.
  • If too much effort is required to cut, reduce tension: Turn the tension screw counterclockwise to loosen slightly.
  • Find the sweet spot where blades close firmly but cut smoothly.

Step 4: Lubricate Moving Parts

  • Put a drop of light machine oil on the pivot point and tension screw. Avoid getting oil on blade surfaces.
  • Open and close the shears a few times to distribute lubricant. Wipe off any excess.

Step 5: Check Results and Retighten

  • Make a few test cuts in scrap wood or branches. Adjust tension as needed until satisfied.
  • Firmly tighten tension screw and pivot screw while blades are closed. Don’t overtighten.
  • Examine blade alignment again and readjust if needed before using the shears.

With these basic steps, Fiskars manual hedge shears will cut like new. Perform adjustments promptly when problems arise to maximize their lifespan.

Adjusting Fiskars Geared Hedge Shears

Fiskars geared hedge shears build mechanical advantage into the design. Adjusting gear mechanisms takes a few extra steps. Here’s how to tune up geared Fiskars hedge shears:

Clean and Inspect

  • Disassemble: Release the latch and remove any protective covers.
  • Clean all parts with a wire brush, mild soap and water. Rinse and dry thoroughly.
  • Inspect: Check for damaged, bent or misaligned parts. Replace if needed.

Adjust Blade Alignment

  • With shears closed, check blade edges for gaps at tip or base.
  • If not perfectly aligned, loosen the pivot screw and realign.
  • Close shears and tighten screw while holding blades in proper position.

Set Blade Tension

  • Test tension by cutting some branches. The gearing should provide clean cuts without crushing.
  • If more tension is needed, turn the adjustment knob 1/4 turn clockwise at a time until optimal.
  • For less tension, gradually turn knob counterclockwise. Find the sweet spot.

Lubricate Gears

  • Put several drops of machine oil or lubricant on the gear teeth.
  • Work mechanism several times to distribute lube. Wipe away any excess dripping.


  • Return all covers and guards to original positions. Secure with screws.
  • Double check blade alignment. Give tension knob final tweak if necessary.

Proper maintenance keeps Fiskars geared hedge shears cutting smoothly season after season. Follow adjustment steps promptly when problems arise.

Adjusting Fiskars Power-Assist Hedge Shears

Fiskars power-assist hedge shears use a spring-loaded mechanism to reduce cutting effort. The added power still requires care and adjustments. Here’s how to adjust Fiskars hedge shears with power-assist mechanism:

  • Use a small brush and mild soap solution to clean housing, blades, gears. Avoid getting water into internal parts.
  • Dry all components thoroughly before proceeding.
  • Visually inspect for any worn, bent or damaged parts. Replace if needed.

Adjust Blade Alignment

  • With shears closed, check the blade edges for gaps at tip or base.
  • If alignment is off, locate the pivot screw(s) and loosen slightly.
  • Realign blades so edges match perfectly when closed.
  • Retighten pivot screws while holding blades in aligned position.

Check Blade Tension

  • Power on shears and make some test cuts in scrap wood. Watch out for moving blades!
  • If blades crush branches or don’t close tightly, increase tension via the adjustment dial or screw.
  • If too much hand pressure is needed, reduce blade tension gradually. Find optimal tension.

Lubricate Components

  • Put 1-2 drops of light machine oil on pivot points and tension adjustment screw.
  • Avoid getting oil on blade surfaces to prevent slippage.
  • Run shears to distribute lube. Wipe away excess dripping.

Reinstall Battery Pack

  • Confirm blade alignment and tension are set correctly.
  • Reinstall battery pack once adjustments are complete.
  • Make final test cuts and tweak tension dial as needed before resuming trimming.
