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

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

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

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

- 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

7-1 Check OIL

Check the Oil status before starting a

machine

pour the Oil when it is needed l after

checking oil status

OIL TYPE BREATHING AIR COMPRESSOR OIL

7-2 AIR SUCTION FILTER

Install the suction filter on the outside

Filter the dust of air

Use the ELEMENT after cleaning when it is

dirty

exchange ELEMENT when it is impossible to use

Using the soiled filter is not good for performance

power consumption and durability

7-3 DRAIN VALVE

Extract the water by opening the drain valve when job is finished

AUTO DRAIN VALVE is automatically opened when the COMPRESSOR is stoped

AUTO DRAIN VALVE isnt worked on condition of having a some trouble in the

SOLENOID VALVE

Be required spacial attention in winter

- Be careful of damaging the COMPRESSOR BODY and LINE by the frozen air line

- Use the hot stove to melt the frozen DRAIN VALVE

- Always operate the ELECTRIC HEATER(Option) in wintertime if there is needed

7-4 PRESSURE GAUGE

AIR PRESSURE GAUGE denotes the pressure of air serviced and OIL PRESSURE

GAUGE denotes that of LUBRICATION OIL

PRESSURE GAUGE is required of special attention for a shock not to smash

Immediately exchange on condition of being damaged

Exchange PRESSURE GAUGE to certified one

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

7-6 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

① ② ③ ④ ⑤

7-9 Checking items after operation

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
