Product Specific Safety Precautions
1. Always stabilize yourself on the ladder or platform before handling and
activating the Pneumatic Garden Shears. A second person may be helpful
to stabilize the tool user when he is climbing a ladder or getting on a platform.
2. Use great caution when cutting shrubs to avoid amputating fingers,
hands or arms. The b lades activate under high pressure. Once the trigger is
pulled, the pneumatic function of the cuttings blades will not stop until the cut
is complete.
3. Always disconnect the air line immediately after use. Squeeze the trigger
after the air line is disconnected to release any residual air in the chamber.
4. Wear work gloves to protect your hands.
Warning: The warnings, cautions, and instructions discussed in this instruction
manual cannot cover all possible conditions and situations that may occur. It
must be understood by the operator that common sense and caution are factors
which cannot be built into this product, but m ust be supplied by the operator.

Oiler and Filter Connection
Dirt, water, and the lack of pneumatic tool oil are major causes for tool w ear . Install
an optional oiler-filter, as illustrated belo w f or better performance.
1. Connect the air tool, air hoses, filter, and oiler to the Compressor Air Outlet
as illustrated below .
The filter and oiler (not supplied) are recommended but not mandatory for
operation. Also, for ease of air supply tr ansport, a portable, rechargeable air
supply would make it easier to maneuver the garden f or trimming.
If the filter and oiler are not used, connect the air hose directly to the 1/4 inch,
18 NPT connector located at the Air Inlet (12) fitting. Also, a few drops of
pneumatic tool oil must be added through the Air Inlet (12) before each use.
Note: Use pipe thread seal or Teflon tape on all threaded connections.
Operation
1. Place the air supply, sufficient length of air hose , and Pneumatic Shears near
the tree or shrubs to be trimmed.
