TOOL USE AND CARE
1. Use the correct tool for the job. Do not force a tool or attachment to do the work of a larger
industrial tool. Maximize tool performance and safety by using the tool for its intended task.
2. This tool was designed for a specific function. Do not modify or alter this tool or use it for an
unintended purpose.
3. Securely hold this tool using both hands, unless it is designed for single hand use.
Using a tool with only one hand can result in loss of control.
4. Maintain tools with care (see Maintenance).
5. Remove adjusting keys and wrenches from the tool before operation or connecting it to a power
source. A wrench or key that is left attached to a rotating part of the tool increases the risk of
personal injury.
6. Avoid unintentional starts. Be sure that the throttle/ignition switch is in the neutral or OFF
position when not in use and before connecting it to any air source.
7. Do not carry the tool with fingers near or on the trigger/switch.
AIR COMPRESSOR
Ensure the compressor used with the tool can supply the required Cubic Feet per Minute at the required
PSI (see Specifications).
1. Use proper size and type of air pressure line and fittings.
2. Use only clean, dry, regulated compressed air at the rated range as marked on the tool.
CAUTION! Do not use an air source other than an air compressor to power this tool.
3. Always use an air regulator, an in-line
filter and a moisture trap in your
compressed air system. These
accessories will increase the tool’s life
and keeps the tool in good working
condition. See the diagram for
recommended components of
an air line.
4. Avoid using an air hose that is too long.
The longer the hose, the lower the
pressure that reaches the tool, possibly
causing it to cease functioning.
As well, a longer hose can become a
tripping hazard.
5. Air tool CFM consumption ratings
are based upon a 25% duty cycle. If
you require continuous duty, a larger
compressor is required.

AIR SOURCE INSTALLATION
WARNING! Never use pure oxygen, carbon dioxide, combustible gases or any bottled gas as an air
source for a tool. Such gases are capable of causing an explosion and serious injury to persons.
1. Set the air pressure regulator on the air compressor to the recommended PSI level (see
Specifications). Do not exceed the tool recommended air pressure. Excess pressure could
result in damage to the tool, to your workpiece or serious injury.
2. Prepare a standard 1/4 in. air connector for use with your tool. Wrap the threaded portion of
the air connector with thread tape. Wrap in a clockwise direction so it will not unravel when
attaching to a quick connector. Attach it to the tool air inlet and tighten.
3. Attach a standard quick connector to the air source’s hose. Attach the air hose to
the tool’s air connector.
4. Check the air line and its connections for air leaks. Do not use the tool until you have
repaired all air leaks.
DISCONNECTING AIR SOURCE
WARNING! Failure to follow these steps could result in severe injury, tool or property damage.
Disconnect tool from air source before cleaning, servicing, changing parts/accessories or
when not in use.
1. Turn hopper regulator to the OFF position.
2. Turn the air regulator to the OFF or L position.
3. Turn off the air compressor.
4. Disconnect the air pressure hose.
5. Discharge any residual pressure inside the tool.

AIR TOOL LUBRICATION
CAUTION! NEVER use a penetrating oil to lubricate the tool. Penetrating oil may act as a solvent that
will break down the grease and cause the tool to seize up.
1. All air tools are packed in grease to prevent corrosion of internal parts during shipping and
storage. We recommend you clean this out to have optimum performance from your new air
tool. Add a generous amount of air tool oil in the air inlet, and then run the tool under no load
until exhaust is clear to remove packing grease.
2. It is very important that the tool is lubricated. Without lubrication, the tool will not work
properly and parts will wear prematurely. Manually adding a drop or two of air tool oil into the
tool’s male connector once a day is better than using an automatic in-line lubricator. In-line
lubricators should only be required when there are multiple users of the same tool.
3. Air tool oil is the only recommended lubricant for use in all air tools. Do not use other types of
lubricants to oil your tools. Using the wrong lubricant will cause premature tool failure
and/or loss of power. Substitutes may harm the rubber compounds in the tool’s O-rings
and other seals.
4. Keep the airline lubricator filled and correctly adjusted. The in-line lubricator should be regularly
checked and filled with air tool oil. Proper adjustment of the in-line lubricator is performed by
placing a sheet of paper next to the exhaust ports and holding the throttle open approximately
30 seconds. The lubricator is properly set when a light stain of oil collects on the paper.
Excessive amounts of oil should be avoided.
5. Avoid adding too much air tool oil during normal use. Too much oil can cause premature power
loss and eventual tool failure. The tool will need to be taken apart by a qualified technician and
cleaned of excess oil.
6. In the event that it becomes necessary to store the tool for an extended period of time
(overnight, weekend, etc.), it should receive a generous amount of lubrication at that time.
The tool should be run for approximately 30 seconds to ensure oil has been evenly distributed
throughout the tool. The tool should be stored in a clean and dry environment.

AIR TOOL PRECAUTIONS
1. Air tools produce more noise than their electric counterparts. Extended exposure to this noise
may cause hearing loss.
a. Wear ear protection gear to eliminate or reduce the noise.
b. If possible add a muffling device to the air tool’s exhaust.
2. Do not operate this tool if the air hose is damaged.
a. Inspect the tool’s air line for cracks, fraying or other faults before each use.
b. Discontinue use if a hissing can be heard from the air line or connectors while operating
the tool.
c. Take the following steps if either of the above situations occur:
i. Tag or mark the tool as 'defective' or 'out of service' until repaired.
ii. Contact a qualified person repair or replace the defective component/hose.
3. Prevent damage to air hose by observing the following:
a. Never use the hose to carry the tool.
b. Keep the air hose of the tool and the tool’s work path while in operation. The hose should
always stay behind the tool.
c. Keep the hose away from heat, oil, sharp edges or moving parts.
d. Do not allow people, mobile equipment or vehicles to pass over unprotected air hose.
i. Position air hose away from traffic areas.
ii. Place hose in reinforced conduit.
iii. Place planks on either side of the hose to create a protective trench.
e. Do not wrap hose around the tool as sharp edges may pierce the hose or cause cracks if
wound too tight. Gently coil the hose and either hang on a hook or fasten with a device to
keep hose together when storing.
4. An air hose under pressure that is damaged or disconnected from an air tool may whip around
and cause damage to the work area or personal injury. Secure the compressor’s air hose to a
fixed or permanent structure with clamps or cable ties.
