7. Use eye protection. Always wear ANSI-approved impact safety goggles.
Wear a full face shield if you are producing flying wood chips.
8. Do not overreach. Keep proper footing and balance at all times. Do not reach
over or across running machines.
9. Maintain tools with care. Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and changing accessories.
Inspect tool air hoses periodically and, if damaged, have them repaired by an
authorized technician.The handles must be kept clean, dry, and free from oil
and grease at all times.
10. Disconnect air line. Unplug air line from the tool when not in use.
11. Avoid unintentional starting. Be sure the switch is in the Off (and locked)
position when not in use and before plugging air line in. Do not carry any tool
with your finger on the trigger, whether it is plugged in or not.
12. Stay alert. Watch what you are doing, use common sense. Do not operate
any tool when you are tired.
13. Check for damaged parts. Before using any tool, a part that appears
damaged should be carefully checked to determine that it will operate
properly and perform its intended function. Check for alignment and binding
of moving parts; any broken parts or mounting fixtures; and any other
condition that may affect proper operation. Any part that is damaged should
be properly repaired or replaced by a qualified technician. Do not use the tool
if any switch does not turn On and Off properly.
14. Replacement parts and accessories. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty. Only use
accessories intended for use with this tool. Approved accessories are
available from Harbor Freight Tools.
15. Do not operate tool if under the influence of alcohol or drugs. Read
warning labels if taking prescription medicine to determine if your judgment or
reflexes are impaired while taking drugs. If there is any doubt, do not operate
the tool.
16. Maintenance. For your safety, service and maintenance should be
performed regularly by a qualified technician.
17. Use tools with both hands when required. Many tools such as chain
saws, drills, routers, etc., require the use of both hands when operating. This
helps maintain tool stability and keeps hands away from the working area of
the tool.
18. Compressed air only. Never use combustible gas as a power source.

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 blades 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 must be supplied by the operator.

Oiler and Filter Connection
Dirt, water, and the lack of pneumatic tool oil are major causes for tool wear. Install
an optional oiler-filter, as illustrated below for 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 transport, a portable, rechargeable air
supply would make it easier to maneuver the garden for 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.
2. Turn the air pressure on at the air supply tank or compressor.
3. Brace yourself on the ground or ladder, then grasp the Pneumatic Shears by
the handle.
4. Place the open blades over the branch to be cut.
5. Pull the Blade Safety Latch (38) down to unlock the blades.

Maintenance
1. After each use, remove the air hose and wipe the Pneumatic Shears with a
clean cloth to remove any dirt and grease buildup.
2. To maintain tool life, always lubricate the air line by adding a few drops of
pneumatic tool oil to the air line before each use.You can also install the
automatic oiler-filter system, as illustrated on Page 5.
3. Before each use, drain water out of the air compressor tank and
condensation from the air lines. Refer to the Air Compressor Operator’s
Manual.
ManualTool Lubrication
1. Disconnect the Pneumatic Shears from the air supply and turn it so the Air
Inlet (12) fitting is facing upward.
2. Hold the Trigger Lever (22) in and place one teaspoon of pneumatic tool oil
into the air inlet (use SAE #10 weight oil if air tool oil is not available). Holding
the Trigger Lever in helps circulate the oil in the air motor.

a towel. Run for a few seconds. Excess oil with be blown out.
