PRECAUTIONS WHEN HANDLING AUTO-GREASING SYSTEM
BLEEDING AIR FROM GREASE CIRCUIT
WARNING
When bleeding the air, the operation must be carried out by two workers who cannot see each other: one in the operator's seat
and one under the machine. When carrying out the operation, maintain contact with each other and check that you understand
the content of your partner's work. If the machine is moved without warning, there is danger that the worker operating under the
machine will be caught in the machine and suffer serious personal injury.
NOTICE
Always bleed the air from the grease circuit. If there is air in the grease circuit, the grease pressure will not rise to the specified
pressure, and this will lead to damage from insufficient lubrication at all parts of the machine.
1. Remove blind plug (2) from the tip of injector manifold (1) at the
rear right of the front axle of the machine.
2. Turn the starting switch ON.
3. Turn manual lube switch (3) ON.
4. Milky white grease mixed with air comes out from the hole for
blind plug (2) in manifold (1). When this milky white grease
changes to normal grease, turn manual lube switch (3) OFF.
5. Install blind plug (2) to manifold (1).
