SERVICE
A correctly adjusted pruner will put the knife blade in the
full open position when hydraulic power is supplied with
the trigger in the off position. There should be no contact
between the hook and link bar when the knife blade is in
this position.
TESTING FOR OPERATION & PERFORMANCE
27. Connect the pruner to a hydraulic source which pro-
duces 3-9 gpm/11-34 lpm at an operating pressure up to
1000-2000 psi/70-140 bar.
28. Turn on the hydraulic source and squeeze the trigger
on the pruner. The knife blade should complete a full cut.
29. Release the trigger. The knife blade should retract to
the full open position.
30. Observe the link bar during the operation of the pruner.
The link bar should not contact the hook at anytime during
operation. If it does, go to the adjustments section of these
instructions and adjust the pruner as necessary.
