5.2 Adjust discharge
Discharge has been adjusted right at the factory. Do not adjust in general
condition. If it is necessary to adjust, do it refer to the above diagram. Turn the
handle in the direction indicated by fig. on it. After finishing adjust, tighten the
jam nut.
5.3 Maintenance of machine
Item
Substance and manner of maintenance
Period
1
Machine must keep clean and dry, regularly clear and
clean various positions of mechanism,
1/wk
2
It is necessary to clear and lubricate various movable
parts (various guide pillars) regularly.
1/wk
3
Check electrothermic tubes whether have some
damage, for this to survey the value of resistance at side
of contactor. If abnormal, change.
1/wk
4
Check various screws and nuts of connecting and tight
to see if loosed, in the light of conditions to tighten or
change.
1/2wks
5
Check various connection of wires to see if loosen or
cracked, then reconnecting or changing wires.
1/month
6
Overall check all of hold-down bolts, see their conditions
to tighten or change.
1/6months
7
Environment around the machine must be clean, dry
and no pollution.
Long term
8
Often observe the altitude of surface of hydraulic oil,
when lower than 3/4, fill up promptly.
Often
9
Often observe the temperature of hydraulic oil, it should
not be higher than 60
Often
10 After the machine runs for 1 year, should change
hydraulic oil, which grade is as 46# wear hydraulic oil.
1/year

1.Check various positions of oil pipes and connectors of pipes
between hydraulic cylinder and integrated unit, if there is any oil
leakage, then changing pipes, combined gaskets or “O” sealing
washers that are damaged.
2.Change hydraulic lock.
3.Check the position between pressure gauge and integrated unit, if
there is any oil leakage, make a correspondent treatment.
4.If there is no problem on what above mentioned, check inner
sealing washers of cylinder to see if damaged and make a
correspondent treatment.
5.Hydraulic oil is unclean, refilter it.

1. If temp. indicates 180
or minus or deviates from indoor temp.,
check thermistor, if damaged, change it.
2. Check connection wire of temp. transmitter.
3. If transmitter is damaged, change connection wire to stand-by
contact, when changing connection, care about the contact of sensor
must be correct; output tip of transmitter are changed
correspondently.
3. Change the transmitter.
