5. CLEANING

MAINTENANCE

WARNING! 

BEFORE CLEANING YOUR AIR 

COMPRESSOR OR CARRYING OUT ANY 

MAINTENANCE PROCEDURE, MAKE SURE THAT IT 

IS DISCONNECTED FROM THE POWER SUPPLY TO 

PREVENT ACCIDENTAL STARTING.

Changing The Oil

The oil should be refilled for the first time after 100 hours of operation. 

Thereafter, the oil should be drained and refilled after every 500 hours 

of service. 

1.  Release any accumulated air pressure from the tank and ensure 

that it is disconnected from the power supply.

2.  Remove the oil drainage 

screw and use a vessel to 

collect the oil from the unit as 

it drains out.

Note: 

if the oil does not drain out 

completely, the compressor may 

be tilted slightly to facilitate this.

3.  Reattach the oil drainage screw.

4.  Remove the breather plug and 

fill the pump with oil up to the 

required level (approximately 

200ml). Ozito compressor 

oil or SAE 15W/40 oil or an 

alternative of the same quality 

is recommended.

5.  Screw the breather plug back 

into place.

6.  Dispose of the old oil in a responsible manner by taking it to 

an old oil drop off point. Check with your local council for more 

information. DO NOT dispose of old oil down the drain.

Cleaning

1.  We recommend that you clean the appliance immediately after you 

use it.

2.  Keep the safety devices free of dirt and dust as much as possible. 

Wipe the equipment with a clean cloth.

3.  Clean the appliance regularly with a damp cloth and some soft 

soap. Do not use cleaning agents or solvents; these may be 

aggressive to the plastic parts in the appliance. Ensure that no 

water can get into the interior of the appliance.

4.  You must disconnect the hose and any spraying tools from the 

compressor before cleaning. Do not clean the compressor with 

water, solvents or the like.

Draining The Pressure Tank

WARNING! 

RELEASE ALL AIR PRESSURE 

FROM THE TANK BEFORE OPENING THE DRAIN 

VALVE. TAKE CARE WHEN DISCHARGING AIR 

THROUGH THE SAFETY VALVE, DRAIN VALVE 

OR AIR OUTLETS. THE DISCHARGED AIR CAN 

CAUSE DUST, STONES, OR ANY OTHER FOREIGN 

PARTICLES TO BE BLOWN THROUGH THE AIR AT 

HIGH PRESSURE.

Air in the compressor tank causes water to accumulate. This must be 

drained off frequently to prevent corrosion and damage to the unit. 

This should be performed after each use and prior to the next 

use.

1.  Turn the drain valve plug 

anti-clockwise (when viewed 

from the bottom of the tank) to 

open it.

2.  Allow all of the water in the tank to drain out.

3.  Replace the drain valve plug and turn it clockwise to tighten it.

Note: 

The tank will not pressurise while the drain valve is open. 

Cleaning The Air Filters

The air filters prevent dust and dirt being drawn in. It is essential 

to clean these filters at least after every 100 hours in service. 

Clogged air filters will decrease the performance of the compressor 

dramatically.

1.  Allow the compressor to run and build up pressurised air in the 

tank. Once the motor has stopped running, turn the compressor off 

and disconnect it from the power supply.

2.  With an air hose and blow gun connected to the regulated pressure 

outlet, turn the pressure regulator until the regulated pressure 

gauge shows a pressure of around 3bar.

3.  Unscrew the wingnut on the 

air filter housing and remove 

the lid.

4.  Remove the filter sponge from 

the housing, tap it and spray 

it with the blow gun to remove 

any dirt. Re-insert it into the 

housing.

5.  Re-attach the lid and wingnut.
