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 the tool is our principle.
Operator‘s instruction
1. Main Applications
This tool has a strong traction power and light
weight only 1.5 kgs. All rivets from 3/32” to
3/16” in all kind of material can be applied with
this tool. This advantage performance make you
job easily.
2. Cautions for Use
2-1 Air pressure
Maximum performance is displayed at the proper
sanding speed, obtainable at a gauge pressure of
6.2 bar. Range-wise, this is an air pressure from 5
to 7 bar (70 to 100 psi)
57
2-2 Air line
Use a 3/4“ 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. 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 on oiler between the
compressor and the tool. Use a 3 HP or larger
compressor for each sander.

2-3 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.

2-4 Inserted tools
Use only the socket or adapter which are in good
condition for use. The intended socket and
adapter for this air tool could are stated as
“Square Drive” on the specification list.
2-5 The approved eye protector, ear-muff,
mouth-muffle, and gloves shall be worn when
operate this tool.
2-6 The working place shall be ventilative.
2-7 Release the on-off device in the case of
energy supply failure.
3. Operation Method
3.1 On-off device
The on-off device is on the inner or outer contour
of the grip. It is a “hold-to-run” type. This tool
stops rotation within few sec, after releasing the
lever. For the sake of safety, place it on a level
plate or on hanger after it completely stops.
3.2 Torque Adjuster
You can adjust the torque by rotating the
knob which indicated by 1 to 6. “1” indicates
the
smallest torque output and “6”indicts the largest
torque output.
3.3 RotatingDirection
One shall make sure the direction of rotation
before actuate this tool. The “F”indicts foreword
and the “R“ indicts reverse. Forward is defined
as clockwise direction seen from the operator‘s
position.
4. Maintenance
4-1 Lubrication
Before connecting the hose , apply 4 or 5 drops
of #60 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,
wash it away immediately. Also, every 3 or 4
hours of operation, oiling is necessary.
4-2 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.
4-3 Disposal
If the tool is too seriously damaged to be used
anymore, drop it in a resource recycling can.
Never drop it into fire.
4-4 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. The power toll shall not be used in potentially
explosive atmospheres.
2. Disconnect the air hose before changing or
adjusting any inserted tools.
3. Prevent long hair or loose clothing from
drawing in while operate this tool.
4. Keep your body in well balanced position and
always wear gloves to reduce the risk of crushing
caused by torque between handle and workpiece.
5. Unexpected direction of rotating could cause a
hazardous situation.
6. Slip/Trip/Fall is a major reason of serious
injury or death. Beware of excess hose left on the
walking or work surface.
7. Wearing eye/face protector could reduce the
danger to person from high speed splinters being
emitted from this tool in the case of inserted tool
failure or emitted from the workpiece.
8. Wearing mouth-muff could avoid inhaling dust
or handling debris from work process that can be
harmful to your health.
9. Excessive high air pressure and too much free
rotation may speed the wear of this tool and
might cause danger situation.
