7-10 Ambient conditions for preservation
Operate compressor at least 10 minutes per a week because Compressors not
running for a long time causes a failure of the machine
Keep the compressor being covered indoor where is dry and clean
Always clean the COMPRESSOR
Check the compressor periodically with maintenance table or decrease of life time
and bad performance will be caused
In case of keeping of COMPRESSOR in damp condition for a long time it needs
unloaded rotation to get compressor oil into the cylinder after removing of the filter
A compressor installed with UNLOAD EQUIPMENT needs oil lubrication after
removing of connection nipple
7-11 V-belt tension
Readjust new V-belt after the first 25 operating hours
The best tension for a belt drive is the lowest possible where the belt under
full load does not slip
A rough value for this is when the belt deflects 10 when pressed with thumb
pressure between the two pulleys

7-10 Ambient conditions for preservation
Operate compressor at least 10 minutes per a week because Compressors not
running for a long time causes a failure of the machine
Keep the compressor being covered indoor where is dry and clean
Always clean the COMPRESSOR
Check the compressor periodically with maintenance table or decrease of life time
and bad performance will be caused
In case of keeping of COMPRESSOR in damp condition for a long time it needs
unloaded rotation to get compressor oil into the cylinder after removing of the filter
A compressor installed with UNLOAD EQUIPMENT needs oil lubrication after
removing of connection nipple
7-11 V-belt tension
Readjust new V-belt after the first 25 operating hours
The best tension for a belt drive is the lowest possible where the belt under
full load does not slip
A rough value for this is when the belt deflects 10 when pressed with thumb
pressure between the two pulleys

7-10 Ambient conditions for preservation
Operate compressor at least 10 minutes per a week because Compressors not
running for a long time causes a failure of the machine
Keep the compressor being covered indoor where is dry and clean
Always clean the COMPRESSOR
Check the compressor periodically with maintenance table or decrease of life time
and bad performance will be caused
In case of keeping of COMPRESSOR in damp condition for a long time it needs
unloaded rotation to get compressor oil into the cylinder after removing of the filter
A compressor installed with UNLOAD EQUIPMENT needs oil lubrication after
removing of connection nipple
7-11 V-belt tension
Readjust new V-belt after the first 25 operating hours
The best tension for a belt drive is the lowest possible where the belt under
full load does not slip
A rough value for this is when the belt deflects 10 when pressed with thumb
pressure between the two pulleys

7-10 Ambient conditions for preservation
Operate compressor at least 10 minutes per a week because Compressors not
running for a long time causes a failure of the machine
Keep the compressor being covered indoor where is dry and clean
Always clean the COMPRESSOR
Check the compressor periodically with maintenance table or decrease of life time
and bad performance will be caused
In case of keeping of COMPRESSOR in damp condition for a long time it needs
unloaded rotation to get compressor oil into the cylinder after removing of the filter
A compressor installed with UNLOAD EQUIPMENT needs oil lubrication after
removing of connection nipple
7-11 V-belt tension
Readjust new V-belt after the first 25 operating hours
The best tension for a belt drive is the lowest possible where the belt under

7-10 Ambient conditions for preservation
Operate compressor at least 10 minutes per a week because Compressors not
running for a long time causes a failure of the machine
Keep the compressor being covered indoor where is dry and clean
Always clean the COMPRESSOR
Check the compressor periodically with maintenance table or decrease of life time
and bad performance will be caused
In case of keeping of COMPRESSOR in damp condition for a long time it needs
unloaded rotation to get compressor oil into the cylinder after removing of the filter
A compressor installed with UNLOAD EQUIPMENT needs oil lubrication after
removing of connection nipple
7-11 V-belt tension
Readjust new V-belt after the first 25 operating hours
The best tension for a belt drive is the lowest possible where the belt under
full load does not slip
A rough value for this is when the belt deflects 10 when pressed with thumb
pressure between the two pulleys

running for a long time causes a failure of the machine
Keep the compressor being covered indoor where is dry and clean
Always clean the COMPRESSOR
Check the compressor periodically with maintenance table or decrease of life time
and bad performance will be caused
In case of keeping of COMPRESSOR in damp condition for a long time it needs
unloaded rotation to get compressor oil into the cylinder after removing of the filter
A compressor installed with UNLOAD EQUIPMENT needs oil lubrication after
removing of connection nipple
7-11 V-belt tension
Readjust new V-belt after the first 25 operating hours
The best tension for a belt drive is the lowest possible where the belt under

7-10 Ambient conditions for preservation
Operate compressor at least 10 minutes per a week because Compressors not
running for a long time causes a failure of the machine
Keep the compressor being covered indoor where is dry and clean
Always clean the COMPRESSOR
Check the compressor periodically with maintenance table or decrease of life time
and bad performance will be caused
In case of keeping of COMPRESSOR in damp condition for a long time it needs
unloaded rotation to get compressor oil into the cylinder after removing of the filter
A compressor installed with UNLOAD EQUIPMENT needs oil lubrication after
removing of connection nipple
7-11 V-belt tension
Readjust new V-belt after the first 25 operating hours
The best tension for a belt drive is the lowest possible where the belt under
full load does not slip
A rough value for this is when the belt deflects 10 when pressed with thumb
pressure between the two pulleys

unloaded rotation to get compressor oil into the cylinder after removing of the filter
A compressor installed with UNLOAD EQUIPMENT needs oil lubrication after
removing of connection nipple
7-11 V-belt tension
Readjust new V-belt after the first 25 operating hours
The best tension for a belt drive is the lowest possible where the belt under
full load does not slip
A rough value for this is when the belt deflects 10 when pressed with thumb
pressure between the two pulleys

- In case of the motors being stopped by overload settle the problem and
press the reset bar then relay will run because relay is standardized by the reset
method of hand-operated
- Check the screw and Fasten it per 4 months
- Clean electromagnetic contact surface per 4 months to remove the reason of noise
- Adjust control circuits voltage to rated voltage of operating coil as exactly as
possible
7-7 MOTOR
Checking points
- Check if the motor shaft can smoothly rotate by the hand or not
- Check The Belt tension and specifications in case of exchanging it
- Check if the power supply(Voltage Frequency Phase)is conform to name plate
- Power connections are performed after verifying the conformity with that of
name plate
Check during Operation
- The operating current of continually used motor must be lower than marked
(name plate) current If the operating current is higher than marked current
check the motor
- In order to check the rotation direction and wiring operate motor under no
loading
- If the rotating direction is reversed interchange two lines among three lines

The filter is consist of three small size (1 2 3 step filtering) or big one size
(1 step filtering)
In case of the filter of small sizes change
A and B step filter with new one and
one step filter can be reused by cleaning
Change filter
- Turn the filter case to CCW with supplied
filter opener and resolve it
- Change new one after cleaning the inner space
- Carefully turn the filter case to CW not to
damage the o-ring

7-10 Ambient conditions for preservation
Operate compressor at least 10 minutes per a week because Compressors not
running for a long time causes a failure of the machine
Keep the compressor being covered indoor where is dry and clean
Always clean the COMPRESSOR
Check the compressor periodically with maintenance table or decrease of life time
and bad performance will be caused
In case of keeping of COMPRESSOR in damp condition for a long time it needs
unloaded rotation to get compressor oil into the cylinder after removing of the filter
A compressor installed with UNLOAD EQUIPMENT needs oil lubrication after
removing of connection nipple

7-6 Other safety Device
PRESSURE SWITCH
Can stop running of compressor in case of over pressured situation
CCW PRESSURE UP CW (CLOCKWISE)
CW PRESSURE DOWN CCW (COUNTER CLOCKWISE)
THERMAL RELAY
- In case of the motors being stopped by overload settle the problem and
press the reset bar then relay will run because relay is standardized by the reset
method of hand-operated
- Check the screw and Fasten it per 4 months
- Clean electromagnetic contact surface per 4 months to remove the reason of noise
- Adjust control circuits voltage to rated voltage of operating coil as exactly as
possible
7-7 MOTOR
Checking points
- Check if the motor shaft can smoothly rotate by the hand or not
- Check The Belt tension and specifications in case of exchanging it
- Check if the power supply(Voltage Frequency Phase)is conform to name plate
- Power connections are performed after verifying the conformity with that of
name plate
Check during Operation
- The operating current of continually used motor must be lower than marked
(name plate) current If the operating current is higher than marked current
check the motor
- In order to check the rotation direction and wiring operate motor under no
loading
- If the rotating direction is reversed interchange two lines among three lines

7-8 AIR CLEANING FILTER
Compressed air is purified by filter so you must change filter per every 50 hours
The filter is consist of three small size (1 2 3 step filtering) or big one size
(1 step filtering)
In case of the filter of small sizes change
A and B step filter with new one and
one step filter can be reused by cleaning
Change filter
- Turn the filter case to CCW with supplied
filter opener and resolve it
- Change new one after cleaning the inner space
- Carefully turn the filter case to CW not to
damage the o-ring

7-10 Ambient conditions for preservation
Operate compressor at least 10 minutes per a week because Compressors not
running for a long time causes a failure of the machine
Keep the compressor being covered indoor where is dry and clean
Always clean the COMPRESSOR
Check the compressor periodically with maintenance table or decrease of life time
and bad performance will be caused
In case of keeping of COMPRESSOR in damp condition for a long time it needs
unloaded rotation to get compressor oil into the cylinder after removing of the filter
A compressor installed with UNLOAD EQUIPMENT needs oil lubrication after
removing of connection nipple
7-11 V-belt tension
Readjust new V-belt after the first 25 operating hours
The best tension for a belt drive is the lowest possible where the belt under
full load does not slip
A rough value for this is when the belt deflects 10 when pressed with thumb
pressure between the two pulleys

7-10 Ambient conditions for preservation
Operate compressor at least 10 minutes per a week because Compressors not
running for a long time causes a failure of the machine
Keep the compressor being covered indoor where is dry and clean
Always clean the COMPRESSOR
Check the compressor periodically with maintenance table or decrease of life time
and bad performance will be caused
In case of keeping of COMPRESSOR in damp condition for a long time it needs
unloaded rotation to get compressor oil into the cylinder after removing of the filter
A compressor installed with UNLOAD EQUIPMENT needs oil lubrication after
removing of connection nipple
7-11 V-belt tension
Readjust new V-belt after the first 25 operating hours
The best tension for a belt drive is the lowest possible where the belt under
full load does not slip
A rough value for this is when the belt deflects 10 when pressed with thumb
pressure between the two pulleys
