3.3 Operating the Equipment
CAUTION
- The maximum supply air pressure of this machine is 0.7 MPa. Using the machine with a supply air
pressure exceeding this limit will lead to death or bodily injury or physical damage due to machine
breakage. Do not set the supply air pressure over 0.7 MPa in any case.
1) Turn the knob of the air regulator counterclockwise for looseness, and then connect the air chuck to supply air.
<Note>
Using an air regulator permits adjusting the supply air pressure to the pump and reducing unnecessary pump
motion, thereby improving the work efficiency and extending the life of the pump.
When the knob of the air regulator is turned clockwise, the air pressure will be increased (the indicator of the
pressure gauge gradually goes from “0” to a larger number). When the knob is turned counterclockwise, the air
pressure will be reduced (the indicator of the pressure gauge goes back to “0”). In the normal operating condition,
the indicator of the pressure gauge is in the range of 0.3 to 0.5 MPa.
2) As the knob of the air regulator is gradually turned clockwise,
the pump is started when the supply air pressure reaches 0.2
or 0.3 MPa. The pump is operated for a while and the pump
and hose are filled with grease.
3) The first applied grease includes the internal air of the pump.
This is not a good condition.
Obtain a perfect condition by the next operation.
First open the check valve and operate the pump until
grease is discharged from a small hole under the check
valve. After grease is discharged in a perfect condition, close
the check valve. At this time, spread paper so that grease
may not come into touch with the hand, and dispose of the
discharged grease. (Fig. 5)
4) Set the supply air pressure to 0.5 to 0.7 MPa.
<Note>
The grease in which air is mixed is cloudy in white.
