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.
Features
1. Finishing of flat surfaces, curved surfaces, and
corner can be freely performed by changing the
shoe.
2. Since it is small, lightweight, and balanced so
that the grinding surface is stable, extremely fine
finishing is possible.
3. The grinding speed can be freely adjusted by
raising or lowing the lever according to the
application.
4. Rear exhaust eliminates flying dust and noise.
Operator‘s instruction
1. Main Applications
Finishing metal carts and products.
Finishing welded surface.
Trimming parts.
Filleting.
Finishing steel cabinets and furniture.
Foundation finishing prior to coating.
Finishing plastic products, glass, and
earthenware.
Finishing stone and decorative wood products.
Finishing sashes and other building material.
Light and medium duty auto, ship and aircraft
finishing.
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)

2-2 Air line
Use a 3/8“ air hose between the compressor an
d
the tool . Compressed air is cooled and its wate
r
content separated, as soon as the air leaves th
e
compressor. A portion of the water content
,
however, is condensed in the piping, and ca
n
enter the tool mechanism, and may cause trouble
.
So, install an air filter and on oiler between th
e
compressor and the tool. Use a 3 HP or large
r
compressor for each sander.

2-3 Air hose
Clean the hose with a blast of compressed ai
r
b
efore connecting the hose to air tool. This wil
l
prevent both moisture and dust within the hos
e
from entering the tool and causing possible rus
t
or malfunction. To compensate for unusuall
y
long hose (over 25 ft), the line pressure should b
e
increased accordingly.

2-4 Sandpaper
The specification of sandpaper ranges from # 4
0
to # 200. Also note that, the maximum operatin
g
speed which the sandpaper can afford shall b
e
higher than the rotation speed of this tool.
2-5 The approved eye protector,ear-muff
,
mouth-muffle, and gloves shall be worn whe
n
operate this tool.
2-6 The working place shall be ventilative.
2-7 Release the on-off device in the case o
f
energy supply failure.
3. Operation, Adjusting And Replacing
Method
3.1 On-off device
The on-off device is under the grip of this tool. It
is a “hold-to-run” type. You can also adjusting
the running speed by raising or lowering the
lever. This tool stops rotation within few sec,
after releasing the lever. For the sake of safety,
put it on a soft cloth or on hanger after it
completely stops.
3.2 Replace the sandbelt
Disengage and remove the sandbelt from the idle
pulley after pushing the idle pulley in the
direction shown below. Replace a new one and
keep your hand away from the idle pulley. Then
push the tension bar indicated on the drawing
and the sandbelt will be propped into the ready
position.
idle pulley tension bar
3.3 Adjusting tracking
If the sandbelt is not centered on the idle pulley,
adjust the hexagon socket head bolt on the idle
pulley bracket with accessory hexagon wrench
key until centering is correct. Turn the hexagon
socket counter clockwise, the belt is moved
toward the bracket, and vice versa.

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 a
t
the air inlet with spindle oil and run it for a short
4-3 Disposal
If the tool is too seriously damaged to be use
d
anymore, drop it in a resource recycling can.
