the necessary maintenance and service activities, the compressor is ready for further operation or storage. All other maintenance
and service works not described in the instructions manual must be carried out at the manufacturer's authorised service centre.
If the compressor malfunction or worn parts, which reduce the quality of the device's operation, are observed, do not carry out
repairs yourself or turn on the damaged compressor. For repair, contact the manufacturer's authorised service centre.
DAY-TO-DAY SERVICE ACTIVITIES
CAUTION! Allow the device to cool down completely before carrying out service activities. Turn off the compressor using the
power switch and then disconnect the power cord plug from the mains socket.
After the fi rst 50 hours, check that the tightness of all screw connections, especially of the screws in the compressor head and
the body, is correct.
Draining condensate from the tank (IX)
After fi nishing work, it is recommended to drain the pressure tank of oil condensate, water, and particles through the valve on a
daily basis. Before starting the draining process, turn off the compressor and unplug the power cord from the socket. Depressurise
the tank, e.g. using a blow gun. Point the blow gun to a safe place (away from people and animals) and pull the trigger until the
tank is empty. Then place a fl at vessel under the drain plug. Unscrew the condensate drain plug in a counterclockwise direction on
the bottom part of the tank. After draining the condensate from the tank, carefully screw on the drain plug. Do not dispose of the
condensate into the soil, river, lake, or sewage system. Dispose of the condensate at an environmentally hazardous substance
collection point.
Changing the oil
Oil in products with the catalogue numbers YT-23300 and YT-23305 should be changed after every 50 hours of the compressor
operation or when you notice in the oil indicator sight glass that the oil is spent (black). Use an air compressor oil with a viscosity
of SAE 15W40 for the compressor.
Oil in products with the catalogue numbers YT-23310 and YT-23320 should be changed once a year or when you notice in the
oil indicator sight glass that the oil is spent (black). Use an air compressor oil with a viscosity of SAE 15W40 for the compressor.
To change the oil, turn off the compressor and unplug the power cord plug from the socket. Prepare and place a suitable vessel
under the oil drain plug (V) so that when the tank is emptied, oil does not spill on the compressor components and the fl oor. Use
a spanner to unscrew the oil drain plug. If the oil does not drain completely, you can slightly tilt the compressor. Once the oil tank
has been emptied, the oil drain plug must be screwed. Pour in new oil so that the level is in the centre of the sight glass. It is for-
bidden to mix diff erent types of oil. If the oil level is too low (below the bottom of the sight glass), there is a risk of the pump seizing.
An oil level that is too high (top of the sight glass) or the use of the wrong type of oil poses the risk of oil entering the pneumatic
system with the air. Do not dispose of the oil into the soil, river, lake, or sewage system. Dispose of the used oil at an environmen-
tally hazardous waste collection point.
Safety valve (X)
The safety valve has been set at the factory to the maximum allowable pressure in the compressor tank. It is forbidden to perform
self-adjustment of the safety valve. If the safety valve is not working properly, contact the manufacturer's authorised service cen-
tre. Approximately every 30 operating hours or at least 3 times a year, make sure the valve is working properly. Turn off the com-
pressor and unplug the power cord plug from the socket. Unscrew the perforated outlet cap of the safety valve counterclockwise.
Carefully pull the cap outwards with your hand. If the valve lets air out, it means that it is working properly. Tighten the perforated
cap by screwing it clockwise. Ensure that the cap is screwed on correctly.
Adjusting the drive belt tension
The products with the catalogue numbers YT-23310 and YT-23320 have a drive belt. Check the belt tension every 100 hours of
the compressor operation and when a drop in compressor performance is noticed. It is forbidden to use the compressor with a
loose or over-tightened drive belt, as this can damage the compressor drive components.
CAUTION! Turn off the compressor and unplug the power cord plug from the socket before starting the belt tensioning
process.
Using an adjustable spanner, release the clips (XI) of the cover by carefully turning them 90 degrees to the right or left until the
clip is loosened. Release all cover clips. Remove the front part of the drive cover. Press the upper part of the drive belt (XII) with
a fi nger at a point between the drive wheels using a pressing force of approx. 3 kg. The correct defl ection of the belt at the control
point should be between 10 mm – 15 mm. If the drive belt tension is correct, you can proceed to the installation stage of the front
drive cover in reverse order to that described in the section describing the cover dismantling. If the belt tension needs to be adjust-
ed, use a hex wrench to loosen the mounting of the rear part of the drive cover to the compressor motor. Then, using spanners,
loosen the motor mounting until the motor can be moved freely in relation to the compressor. Adjustment is made by moving the
motor relative to the compressor. Set the correct belt tension by moving the motor to the right or left relative to the compressor. Bolt
all motor mountings and the rear cover mounting to the compressor motor. Ensure that all connections are securely screwed and
will not move during the compressor operation. You can proceed with the assembly of the front drive cover in reverse order to that
