Foreword
Sumake is a 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 thetool is ourprinciple.
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
p
repared to equip you with the knowledge
necessary to keep it on the job efficiently.
Operator‘s instruction
1. Cautions for Use
1-1 Air pressure
Maximum performance is displayed at the proper
sanding speed, obtainable at a gauge pressure of
6.2 bar. Range-wise, this is anair pressure from5
to7 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 separated, 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 a
n
air filter and an oiler between the compressor an
d
the tool. Usea 3 HP orlarger compressor for eac
h
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 whe
n
operate this tool.
1-5 The working place shall be well ventilated.
1-6 Release the on-off device in the case o
f
energy supply failure.
2. Operation, Adjusting And Replacing

t
thedesired chisel from the open end of the quic
k
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 scre
w
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 ope

2-3 Replace and adjusting
There isno user serviceable part inside this tool.
Please sendthe tool to aqualified personnel orour
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 of a 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 Orderingservice Parts

for replacement of parts and components, contact
the sale agent fromwhom you purchased the tool or
the service division of our company.

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,
couldbe 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
periodof use break due to fatigue.
7. Keep your body balance and beware ofthe break
ofthe 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
whippingcompressedairhose.
