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
Exceptionally versatile tool for jobs like tire
scuffing, cleaning tire moldings, porting and
relieving engines, and general high-speed
polishing and grinding. Especially useful in
confined areas.
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 an air pressure from 5
to 7 bar (70 to 100 psi)

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 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 Fix/take away the insert tool
The figure below indicates how to fasten and
loose an insert tool. Before using this tool, one
should make sure that the insert tool is fixed in
the collet very tightly.
Loose
Fasten
One should also get a habit of checking the
weariness of the insert tool in order to increase
the efficiency and safety.
2.2 On-off device
To operate this tool, just push the lever toward
the tool itself. The tool continuously
reciprocates as one push the lever down and it
stops running 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 #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,
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.

Specific safety instructions
Warnings shall be given about any specific or unusual hazards associated with the use of the power tool. Such warnings shall indicate the nature of
the hazard, the risk of injury and the avoidance action to take.
General preparation and connection:
1. Before connecting the air hose, apply 4 to 5 drops of SAE#10-20 spindle oil at the air inlet. Also, every 3 to 4 hours of operation, oiling is
necessary. Twist Teflon thread tape to ensure a proper seal air inlet. Then tighten the air coupler into air tool.
2. The supplied compressed air must be clean and dry, with the appropriate oil mist. Use an air treatment unit; filter, regulator and lubricator.
3. Please refer Fig.1 illustration shows the correct mode of connection to the air supply system which will increase the efficiency and useful life of
the tool.
4. The quick connect coupling and hose must have sufficient air flow capacity. We recommend an air hose with a diameter of 10mm (3/8”).
5. To ensure a good performance. The operation pressure at the compressed air inlet should not exceed 6.3bar (90psi) (unless indicated
otherwise). Higher operating pressures may cause damaged or excessive wear. Operating pressures below 5.3bar may cause pressure or
power loss.
Risk of injury
1. Compressed air can inflict serious injuries. Therefore never point the air hose at another person or yourself.
2. Shut –off the air supply and disconnect the tool in case:
➢You want to change or replace accessories.
➢You want to clean, repair or maintain the tool.
➢The tool is not going to use for some times.
3. Check compressed air hose before use. If it is damaged, broken, torn, or deformed, the hose is not to be connected to the tool.
4. Always check the pneumatic couplings before using the tool. If they show signs of damage, fracture, cracking or excessive corrosion, the
respective tool or the air hose is not to be used.
5. Use only qualified adapters and connectors, In case of wear they are to be replaced immediately.
6. Only use air pipes that are fit for the use at maximum pressure.
Maintenance instruction:
1. Dry the filter (fig1) and the air inlet of the tool.
2. Lubricate the quick connect coupling to prevent blocking.
3. Air tool require lubrication throughout the life of the tool. The air motor and bearing uses compressed air to start the tool. The moisture in
