Pre-Operation Checks

You must check everything before using a screw air compressor. This helps you stay safe and makes the machine work well. Using a checklist stops problems and keeps things running right. Sollant makes compressors that are easy to care for and last a long time. These checks are simple to do.

Power Supply Inspection

Look at the power supply before starting the compressor. Make sure wires and plugs are tight and not loose. Check for damage or wear on all cables. If you see broken wires or loose ends, fix them now. A good power source keeps the motor safe and stops sudden shutdowns.

Tip: Always use the right voltage and circuit protection for your screw air compressor. This lowers the chance of electrical problems.

Oil Level and Lubrication

The right oil level and good lubrication help your screw air compressor work well. You should:

Keep the oil level close to full.
Do not let oil drop below two-thirds full.
Use good lubricant and check oil often.
Never use old or bad oil because it causes more wear.

Both the amount and quality of oil are important. Not enough oil or bad oil makes parts wear out faster. Checking often helps you find leaks or low oil early. Sollant compressors have clear oil gauges and easy-to-reach oil tanks.

Safety Devices

Safety devices keep you and your machine safe. Before you start, check all safety valves, pressure relief devices, and emergency stops. You should:

Check the safety valve every year to follow safety rules.
Make sure covers and guards are in place.
Test emergency stop buttons to see if they work fast.

Sollant compressors have strong safety features that are easy to check. Never skip these checks because they stop accidents and damage.

Cooling System

A good cooling system stops your screw air compressor from getting too hot. You need to:

Make sure the fan and radiator are clean and not dusty.
Check that water flows well if it uses water cooling.
Look at hoses and connections for leaks or blocks.

If the cooling system does not work, you might have:

Broken inside parts
Shorter life for the compressor
Less air and weaker performance
More energy use and higher costs

Sollant compressors have tough cooling systems for hard jobs, but you still need to check them every time.

Air Filters and Pipes

Clean air filters and pipes help your screw air compressor work better. You should:

Check air filters for dirt or clogs. Change them if needed.
Look at pipes, hoses, and fittings for leaks or damage.
Listen for strange sounds or shaking that could mean trouble.
Check for missing O-rings, worn valve packing, or bad seals.

Dirty filters make the compressor work harder and get hotter. Bad filters let dirt into the oil, which wears out parts faster. Sollant compressors have easy-to-clean filters and strong pipes, so these checks are quick.

Note: Checking filters and pipes often keeps your compressor working well and saves money on repairs.

Startup Procedures

Starting your screw air compressor the right way helps you avoid problems and keeps your equipment safe. Follow these steps to make sure your machine runs smoothly every time.

No-Load Start

Begin with a no-load start. This means you start the compressor without any air demand. You should:

Check inside the compressor for any objects left during shipping.
Make sure you use the correct circuit breaker and wires. The power supply must connect properly, and the indicator light should turn on.
Look at the oil level. It must stay above the red warning line before you start.
Inspect all connection points for leaks. Check for air, oil, or water leaks.
Press the ‘Start’ button to turn on the compressor.
Watch as the compressor begins to run. The intake valve opens, and the exhaust pressure pointer rises.
After starting, check the oil level again to make sure it stays normal.
Look again for leaks at all connection points.

Tip: Always start your screw air compressor under no-load conditions. This protects the motor and other parts from sudden stress.

Initial Monitoring

After you start the compressor, pay close attention to how it runs. Listen for any strange sounds or vibrations. Watch the control panel for warning lights or error codes. Sollant compressors have easy-to-read displays that help you spot problems early. If you hear odd noises or see anything unusual, stop the machine and check for issues.

Gradual Load Application

Once you confirm everything works well, you can apply load slowly. Here is how you do it:

Turn on the cold dryer if your system uses one.
Let the compressor run without load for about 10 seconds.
The machine will switch to loaded mode. The display changes from ‘Automatically unloaded’ to ‘Automatically loaded.’
Check all indicators to make sure values stay within safe limits.
Record important numbers, like pressure and temperature, in your logbook.
Let the compressor run for 7-10 minutes. The air tank pressure will rise slowly.
Open the manual drain valve under the air tank to remove any water.
Your startup is now complete.

Note: A slow and careful startup helps your screw air compressor last longer and work better.

Monitoring During Operation

Watching your screw air compressor while it works helps you find problems early. This stops damage and keeps your machine running well. Sollant compressors have smart control panels and easy-to-read screens.

Instrument Readings

Check the instrument readings often when the compressor is on. Look at the pressure, temperature, and oil level gauges. Write these numbers in your logbook. This helps you notice changes that could mean trouble.

Take vibration readings every three months during maintenance.
Once a year, record all main readings for long-term tracking.
Checking often helps you find problems and keep your compressor working well.

Sollant compressors have simple panels. You can see all important data quickly. This makes it easy to watch your machine.
