Daily maintenance
Carry out the following checks daily before using the machine.
1 Check that nuts and screws are tight.
2 Check that the air hose is in full working order and in good
condition.
3 Start the power source and check that the power cutter
functions by starting the machine with the switch in the
rear handle. Check that the blade stops when the switch
is released.
4 Checking the blade guard
5 Check the condition of the cutting blade.
6 Check the tension of the drive belt.
7 Check that the available compressor provides the correct
air pressure, 7 bar and the correct air volume of 2.8-3.5
m3/min for K40 and 2.0-2.4 m3/min for K30.
8 Use an air hose that is at least 3/4' (19 mm).
9 Blow any dirt and moisture out of the hoses before
connecting the machine.
10 Connect the air hose to the machine and secure the
couplings. Turn on the air pressure and check that there is
no leakage.
11 Turn off the air supply and release the pressure before
using the machine. Check that the oil container is filled
with oil intended for pneumatic machines. When an oil
dispenser container is not used, you can pour a small
quantity of oil directly into the air hose. When the machine
is then started the motor will be lubricated by the oil blown
through the motor.
12 Use a compressor with a moisture separator.
13 Inspect the water adjustment control.
14 Check the function of the water filter.
Motor repairs can be extremely expensive.
Motor failure can be caused by the following:
1 Use of the machine without an oil dispenser container
connected.
2 Condensation water in the air supply, caused by
condensation in the hoses, compressor tank, valves, etc.
Condensation results in rust attack on the metal parts
inside the motor.
3 Dirty air hoses or pneumatic couplings.
4 Uncleaned air system. Cleaned refers to pouring a small
quantity of oil into the hoses and starting the machine so
that the oil is blown through the motor. The oil rinses out
all moisture and protects the motor parts. Oil for
pneumatic machines must be used. Ask your dealer for
the right type of oil.
Do not use engine oil or hydraulic oil.
