Foreword
We are the manufacturer and exporter of air tools
since established. We have devote all our efforts
in improving quality and tools?life. As well as
the noise and vibration of tools. Bring all of you
working efficiences, profits, and enjoy using the
tool is our principle.
Features
This air tool is a pneumatic tool that injects high
efficiency into manual chipping, riveting, breaking
of concrete and asphalt etc. Your care in handling
it is, however, important if performance is to be
realized over a long period of time. This booklet is
prepared to equip you with the knowledge
necessary to keep it on the job efficiently.
1. Cautions for Use
1-1 Air pressure
Maximum performance is displayed at the proper
sanding speed, obtaina ble at a gauge pressure of
6.2 bar. Range-wise, this is an air pressure from 5
to 7 bar (70 to 100 psi)
57
1-2 Air line
Use a 3/8?air hose between the compressor and
the tool . Compressed air is cooled and its water
content sep arated, as soon as the air leaves the
compressor.

daily
A portion of the water content, however, is
condensed in the piping, and can enter the tool
mechanism, and may cause trouble. So, install an
air filter and an oiler between the compressor and
the tool. Use a 3 HP or larger compressor for each
sander.
1-3 Air hose
Clean the hose with a blast of compressed air
before connecting the hose to air tool. This will
prevent both moisture and dust within the hose
from entering the tool and causing possible rust or
malfunction. To compensate for unusually long
hose (over 25 ft), the line pressure should be
increased accordingly.
Drainage
1-4 The approved eye protector, ear -muff,
mouth-muffle, and gloves should be worn when
operate this tool.
1-5 The working place shall be well ventilated.
1-6 Release the on -off device in the case of
energy supply failure.
2. Operation, Adjusting And Replacing
Method
2-1 Inserting a chisel
First disconnect the air horse from this tool. I nsert
the desired chisel from the open end of the quick
change retainer so that the retainer could hold the
protuberance on the chisel shank. Secure the
retainer and the chisel to the gun body by screw
the retainer on the closed end in the clockwise
direction . Loose the retainer and the chisel from
the gun body by screw the retainer on the open
end in the reverse direction.

2-2 On-off device
Please note that the tool never running unless the
insert tool is properly fixed on the gun body. To
operate this tool, just push the trigger, which is on
the grip, down. The tool continuously reciprocating
as one push the trigger down and it stops running as
the trigger is released.
For the sake of safety, put it on hanger or on a soft
flat pad when not in use.
2-3 Replace and adjusting
There is no user serviceable part inside this tool.
Please send the tool to a qualified personnel or our
service section to repair or/and replace worn parts.
3. Maintenance
3-1 Lubrication
Before connecting the hose , apply 4 or 5 drops of
SAE #10 spindle oil at the air inlet. Use ofa thicker
oil can lead to reduced performance or malfunction.
If a thicker oil is used by accident, wipe it away
immediately. Also, every 3 or 4 hours of operation,
oiling is necessary.
3-2 Storage
Avoid storing the tool in a location subject to high
humidity. If the tool is left as it is used , the
residual moisture inside the tool can cause rust.
Before storing and after operation, oil the tool at
the air inlet with spindle oil and run it for a short
time.
3-3 Disposal
If the tool is too seriously damaged to be used
anymore, drop it in a resource recycling can. Never
drop it into fire.
3-4 Ordering service Parts
For further operational and handling information or
for replacement of parts and components, contact
the sale agent from whom you purchased the tool or
the service division of our company.
*In ordering parts and components, give each part
number, name and quantity.
Warning
1. This tool is not insulated for coming into contact
with electric power source.
2. It is forbidden to use this tool in explosive
atmospheres and do not put any combustible
material near the workpiece since it might emit
sparks when working on hard material.
3. Check the wear of the insert tool and the retainer
before operating this tool.
4. Working with this tool will generate dust,
depending on the material being worked on,
could be harmful to the operator
5. This tool can cause the ejection of particles at
chipping or demolishing work , hence the
operator shall wear appropriate protective device
and do not let other person near the work area.
6. The insert tool and the retainer on heavy types
are exposed to heavy strains and can after a long
period of use break due to fatigue.
7. Keep your body balance and beware of the break
of the severed workpiece.
8. If one needs to use the free hand, although it is a
source of vibration damage, we suggest place the
hand by holding the tool in the part between the
retainer and the grip and do not place the hand
on the rear part by pushing the tool. The former
posture provides the operator more balance than
the latter one.
9. Always disconnect the tool from the air power
source when maintenance, placing any insert
tool, and not in use.
10.Never carry the tool by hose and beware of a
whipping compressed air hose.
11.The workpiece shall be fixed by proper device.
