g Check the torque of the attachment bolts for the engine; tighten
them, if necessary.
For more information concerning the engine, you can find it in the book deliv-
ered with this machine.
2. Carriage:
Lubricate all mechanical moving parts in the system. Check that all
nuts and bolts have been correctly tightened.
3. Pump system
• Cleaning the high-pressure control:
When the high-pressure valve has been closed, the pressure gauge
should not indicate any pressure. Similarly, if the spray gun is connect-
ed and closed, the pressure gauge should not indicate any pressure. If
the pressure gauge does indicate a pressure, this implies a leakage in
the system or that the one-way valve may be dirty or damaged. In
which case stop the machine, unscrew the hose coupling and clean or
replace the one-way valve. Also, check the condition of the O-ring and
gasket.
Regularly clean the high-pressure control. Carefully remove all dirt!
Proper maintenance will increase the service life of this part.
• Changing the pump oil:
Change the pump oil in the high-pressure pump after every 1000
working hours (or at least once a year).
For more information concerning the pump, you can find it in the enclosure de-
livered with this machine.
8.4 Maintenance wheel bearings and wheel nuts.
After the first 50-100 km the wheel nuts must be checked on a good seat. If
the seat is not good, pull the wheel nuts with a torque setting of 110Nm.
Aluminium rims: 100Nm!
After every 5000 km this must be repeated. Also, check the play on the bear-
ings.
If there is any play on the bearings, we recommend advising our service de-
partment.
Supply the wheel nave after every 10000-km with new grease. Advise our ser-
vice department. You can combine this with a thoroughly service maintenance
of your machine.
8.5 Check the brake drums and the brakes.
Proceed as follows:
1. Disconnect the brake cables and hose and check that the brakes oper-
ate smoothly.
2. Rotate the brake drum in the normal direction and fasten the adjusting
nut until the brake drum starts rubbing. Then rewind the nut approx.
one third of a turn.
3. Connect the brake cables and fasten them on the brake horizon with a
safety nut (when the hand brake has been operated, the brake horizon
has to be below the main frame).
4. Attach the brake hose to the brake horizon and lock it by means of two
safety nuts.
