Pruner: Won't Telescope or Binds

Your pruner’s clamps lock the drive shafts in place when telescoping. If the clamp no longer tightens down and locks the shafts in place, you will need to replace it. To do this, simply remove all the screws holding it around the drive shaft housing, and replace it with a new compression clamp.

The knob tightens and loosens the pressure on the compression clamp that allows you to extend or retract the drive shaft. If the knob breaks or strips, simply replace the knob with a new one by unscrewing the old one all the way off and installing a new one.

The shafts of your pruner transmit the power from the engine to the pruner head. If a shaft is binding, you will need to repair or replace it. To begin this process, first loosen the locking nuts and handle that secures both upper and lower drive shafts together. Then, loosen the screws on the pruner head or engine housing, and remove the center screw. Next, remove the old shaft and replace it with a new one. Re-insert the new shaft into the engine housing or pruner head by lining it up with the aligning hole, and tightening the screws down. Re-insert the aligning screw and tighten it down, then re-attach the 2 drive shafts back together and tighten down the locking nut and handle.
