Pole pruners serves as an essential home landscape maintenance tool. This pruning tool features a sharp curved hook above a second sharp blade attached to a long rope that extends down the pole. The C-shaped blades fit around medium sized tree branches to aid pruning of hard to reach branches. Landscapers yank hard on the rope after positioning the branch in the center of the blades. Pole pruners consist of an aluminum pole and often telescope to reach higher branches. Maintaining a pole pruner requires cleaning after use, oiling moving parts/blades and sharpening blades as necessary.
Wear thick gloves to protect hands from the sharp serrated edges of the saw blade.
Moisten a cleaning rag with a small amount of WD-40 lubricant. Wide the blade carefully to remove dirt and debris that accumulated with use. Apply a light spray to the hinges and other moving parts of the pole pruner. Wrap the cord around the pole and store upright, making sure to avoid rubbing the saw blade against the wall or other items. Proper storage prevents dulling of the saw blade.
Remove rust from the blades by scrubbing the areas with a stiff wire brush. Apply lubricant with a soft rag after rust removal to inhibit future rust formation.
Service the pole pruner yearly by carefully examining the entire aluminum pole to check for defects. Check the rope lanyard for fraying and replace if necessary. If branch removal becomes difficult, check cutting surfaces for dullness that may require sharpening.
Secure the saw blade between the clamps of a vise with the serrated side facing up. Wear goggles to protect your eyes from any metal shavings.
Apply the round file to each tooth of the saw blade, angling the blade with the beveled edge of the saw. Press lightly with the file back and forth across each tooth. Flip the saw blade over and lightly sand any protruding rough edges. Pole pruner blades should need infrequent sharpening since the serrated blade design inhibits dulling of the cutting surface.
