SAFETY RULES
DANGER：
Indicates an imminently hazardous situation which, if not avoided, will result in death or serious
injury.
WARNING：Indicates a potentially hazardous
situation which, if not avoided, will result in death or serious
injury.
CAUTION：
Indicates a potentially hazardous situation which, if not avoided, will result in minor or
moderate injury.
NOTE：Alerts the operator to useful information.
It is essential that the operator of this tool take
the necessary precautions to prevent the level of danger
indicated by the symbols above. Any employer is also responsible for distributing this instruction manual and
ensuring that all users read, understand and follow
the directions as described in the manual, safety warnings,
etc.
DANGER
Use only filtered, lubricated, regulated compressed air
only. Use of a compressed or flammable gas as a
power
source may cause the stapler to explode and
cause death or serious injury.
Operate the tool within the specified air pressure
stated in the specifications and warning labels.
Sparks sometimes fly when the tool is used. Do not use
the tool near volatile, flammable materials such as
gasoline, thinner, paint, gas, adhes
ives, etc.; they will
ignite and explode, causing serious injury.
Do not carry the tool with your finger on the
trigger or hand it to someone in this condition.
Accidental firing can be extremely dangerous.

WARNING
Always disconnect the stapler fr
om the air supply before ANY KIND of adjustment, clearance of jams,
service, cleaning, re-locating and during non-operation.
Always wear safety goggles with side shields and hearing protection. Employers and users are responsible
for ensuring anyone near the stapler is also protected.
When the stapler is being loaded or is connected to the air compressor, never place your hand or any other
body part in the stapler discharge area.
Use only parts and fasteners recommended by specification. Do not modify the stapler without authorization.
CAUTION
Do not throw the tool, strike the body in any way or use the tool as a hammer to knock material in place.
NOTE
Do not use the tool if it is not loaded, as this will accelerate wear on the stapler.
Make sure all hoses and fittings are free from damage and dirt, replacing any necessary items.
LUBRICATION AND MAINTENANCE
CAUTION：
Do not store the stapler in cold weather as the valves and mechanisms may freeze up, causing
the tool to operate incorrectly.
Be sure to disconnect the stapler from the air supply before lubricating.
The stapler must be lubricated before the firs
t use, and before and after each additional use. Oiling prevents
rust and extra wear. Manual lubrication can be skipped if an Oiler is used.
An Oiler conveniently provides oil circulation that
also increases the efficiency and life of the tool. An Oiler
should be used if the stapler is used heavily or constantly. The Oiler should be checked daily for oil level.
NOTE
If operating in cold weather or below freezing, use permanent
antifreeze as a lubricant. Some drying agents
may damage o-ring and seals, be sure to check these.

AIR COMPRESSOR AND CONNECTIONS
NOTE：
The air pressure required depends on fastener size and type of material to be stapler. Never exceed
the air pressure recommended by specifications.
If stapler do not drive down tightly, adjust
to a higher pressure setting until satisfactory. Reduce air pressure
if the fasteners are being driven too deeply.
Adding Quick Connector on the stapler and Quick coupler on the air hose can improve performance.
WARNING OF DRIVING STAPLES
During the process of assembling the AIR HOSE, do not put your finger into the TRIGGER.
l It could cause the risk with an unexpected firing
Please get the DRIVER GUIDE tight on woods and then driving the TRIGGER.
l The staples can be driven with the driving the TRIGGER
OPERATING THE STAPLER
Add a few drops of high speed spindle oil or air tool oil into the air inlet.
Check the operation of the trigger, and load stapler into the magazine.
Connect the stapler to the air compressor.
Test the depth of stapler by d
riving stapler into a sample piece of wood. If the stapler do not reach the desired
depth, adjust the air pressure.
