Adjustments for LHFS-210003 Pruners
Wear eye protection when operating
or servicing this tool.
Failure to wear eye protection can
result in serious eye injury from
flying debris or hydraulic oil.
Do not dress the blade or inspect, adjust or clean
tool when it is connected to a power source.
Accidental start-up can result in serious injury.
Failure to observe these warnings can result in
severe injury or death.
Tension Adjustment
Follow the tension adjustment procedure carefully.
Too little tension between the hook and blade may
result in damage to the tool.
The hook and blade must fit together snugly. If the fit is
too tight, the cutter does not perform properly. If the fit
is too loose, the tool does not cut cleanly.
1. Disconnect the tool from the power source.
2. Remove items 1–6 and 7–9 in numerical order. See
the Cutter Head Disassembly illustration.
3. Set the tension to a heavy amount of drag as
follows:
Without connecting the tool to a hydraulic power
source, move the blade by hand. Tighten or loosen
item 13 until the cutter produces a moderate
amount of drag when the blade is moved by hand.
4. Assemble in reverse numerical order.
Notes:
• Tighten the hardware so that the blade and hook fit
together snugly.
• If the slot in the bolt lock (9) does not line up with
the hole in the hook (17), turn the bolt lock over. This
allows it to line up.

Closure Adjustment
The closure adjustment is set at the factory and should
not be adjusted until repeated blade sharpening or new
blade installation makes it necessary.
When closed, the blade should overlap about 1/3 of the
face of the cutter hook.
1. Disconnect the tool from the power source.
2. Remove cap screws and washers, as shown. Insert
one of the cap screws into the blind hole and tighten
until the entire cutter head assembly is loose on the
extension tube.
3. Slide the cutter head assembly up or down on the
tube until the blade overlaps 1/3 of the face of the
hook.
4. Remove the cap screw from the blind hole.
5. Install the cap screws and nuts at their original loca-
tions. Tighten securely.
6. Connect the tool to the power source and actuate
several times. The action should be smooth and
uniform from fully open to fully closed. Snug up any
loose linkage hardware.
