Foreword
Sumake is a manufacturer and exporter of air tools since established. We have devote all our effort in
improving quality and tools life. As well as the noise and vibration of tools. Bring all of your working efficiency,
profits and en oy using the tool is our principle.
Operator's instruction
1.Main Applications
The most popular 1/2" drive impact wrench It combines compact size and light weight with high
torque to meet a wide range of applications It is ideal for overall automotive service, body shop, farm
and light truck work
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 3/4" 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 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 started 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 Ad uster
You can ad ust 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 Rotating Direction
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 sub ect 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 short time.
4-3 Disposal
If the tool is too seriously damaged to be used any more, drop it in a resource recycling can. Never drop
it into fire.
4-4 Ordering service Parts
For further operational and handling information or of 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 ad usting 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 ma or reason of serious in ury 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 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.
