Key Components
Cutting blade - the sharpened, beveled blade that moves past the counter blade to make the cut.
Counter blade - supports the branch during bypass cutting and must not be sharpened.
Blade lock knob - secures the blade gear and helps hold the cutting assembly in position.
Locking knob - secures the cutting blade and is removed with the included hex wrench during blade replacement.
Trigger switch - cycles the cutting blade after the tool has been switched on.
On/Off switch - must be switched on before the trigger can operate the pruner.
Handle - provides the main one-handed grip for controlled pruning.
LED work light - illuminates the cutting area while the powered tool is operating.
Battery compartment - locks the compatible 20V ECOSHARP® battery into the pruner.
Battery indicators - four LEDs show approximately 25%, 50%, 75%, or 100% charge.

Unpacking & Inspection
-
Check the carton contents
Confirm the pruner, battery, charger, whetstone, both wrenches, hard shell case, and manual are present.
-
Inspect for shipping damage
Examine the housing, switches, battery, charger cable, blade, counter blade, knobs, and case before use.
-
Confirm the blade is secure
The cutting blade is pre-installed. With the battery removed and gloves on, verify the blade, cover, lock knob, and locking knob are fully seated and tight.
-
Keep packaging away from children
Plastic bags, foils, and small parts can create a suffocation hazard.
Battery Charging
-
Remove the battery
Press the battery push-lock button and pull the battery out of the compartment.
-
Connect the charger
Plug the charger into a suitable AC outlet, then connect the charger plug to the charge socket on the battery.
-
Watch the charger indicator
The indicator is red while charging and turns green when charging is complete.
-
Disconnect in the correct order
Unplug the charger from the wall outlet first, then disconnect the charger plug from the battery.
Starting, Cutting & Stopping
-
Install the charged battery
Slide the battery into the compartment until it clicks securely into place.
-
Check the cutting area
Make sure the blade is clear of people, animals, wires, and other objects. Wear eye protection and protective gloves.
-
Switch the tool on
Press the On/Off switch before touching the trigger.
-
Make one controlled cut
Place only one branch within the blade's rated capacity, keep your free hand away, and pull the trigger. Release and press the trigger again for the next cut.
-
Stop the pruner
Release the trigger. Wait at least five seconds before restarting to avoid heat buildup and motor damage.
-
Finish safely
Before storage, close the cutting blade while the pruner is still powered on. Press and hold the trigger until the blade closes, keep the trigger held, and press the On/Off switch to power the unit off while the blade remains closed. Once the blade is fully closed and the unit is off, release the trigger, remove the battery, and wait for all movement to stop before cleaning, carrying, or storing it.
Pruning Tips
Cut one branch at a time
Do not bundle stems or crowd several branches into the blade.
Leave room above a bud
Make the cut at least 0.3 in. (8 mm) above the bud so the wound can heal properly.
Slope the cut away
Angle the cut away from the bud so rainwater can run off.
Remove stems at the branch point
When removing an entire stem, cut back to the location where it branches.
Keep the cutting path visible
Use the LED work light as an aid, but never cut where wires, hard objects, or the branch's far side cannot be checked.
Safe Operating Practices
Protect your eyes and hands
Wear safety glasses with side shields, protective gloves, sturdy footwear, and appropriate work clothing.
Keep the free hand away
Never hold a branch close to the cutting point or reach between the blade and counter blade.
Use only for pruning
Use the tool for suitable stems, twigs, and branches within its rated cutting capacities. Do not use it as a general-purpose cutter.
Keep the tool dry
Do not expose the pruner, battery, or charger to rain, moisture, or wet conditions.
Remove the battery before service
Disconnect the battery before blade handling, cleaning, inspection, maintenance, transport, or storage.
Cutting Blade Replacement
-
Remove the locking knob
Use the included hex wrench to remove the locking knob that secures the cutting blade.
-
Remove the blade gear
Use the included socket wrench to remove the blade gear from the blade lock knob.
-
Open and lay the pruner flat
With the blades open, place the pruner on a stable surface and remove the two screws securing the blade cover.
-
Remove the cutting blade
Wearing gloves, grasp the cutting blade and pull it away from the blade bolt and counter blade.
-
Install the recommended replacement
Reassemble the blade bolt, new cutting blade, and counter blade in the sequence shown in the operator's manual. Ensure the rack gear teeth contact the pinion.
-
Reassemble and check
Reinstall the blade cover, blade lock knob, blade gear, and locking knob in reverse order. Confirm the blade is fully seated and every fastener is secure before reinstalling the battery.
Blade Sharpening
-
Remove the battery and open the blade
Wear protective gloves and hold the open pruner securely with the beveled cutting edge accessible.
-
Set the whetstone angle
Place the included whetstone against the beveled edge at approximately 15 degrees.
-
Use one-direction strokes
Move smoothly from the base of the blade toward the tip four to five times. Do not use a back-and-forth sawing motion.
-
Remove the burr
Turn the pruner over and slide the whetstone flush along the flat side only to remove the burr created during sharpening.
-
Check the result
Do not over-sharpen. Inspect the edge frequently and replace a blade that is bent, cracked, heavily worn, or otherwise damaged.
Cleaning, Lubrication & Storage
Remove sap and trimmings
Wipe the tool with a soft cloth moistened with mild soap. Do not immerse any part of the pruner or allow liquid inside the housing.
Lubricate the center bolt
Apply oil around the center bolt, then open and close the tool about ten times to work the oil into the cutting assembly.
Inspect the blade and fasteners
Do not operate with a loose, dull, bent, cracked, or damaged blade. Confirm the cover, knobs, blade bolt, and gear are secure.
Prepare for extended storage
Fully charge the battery and clean the pruner. Before removing the battery for storage, close the cutting blade: with the unit powered on, press and hold the trigger until the blade closes, keep the trigger held, and press the On/Off switch to power the unit off. Once the blade is fully closed and the unit is off, release the trigger, remove the battery, and store the kit in its case in a secure, dry place between 41°F and 104°F (5°C-40°C).
