Check & Maintenance of Hydraulic System
a)
Check motor and pump for any damage.
b)
Check hoses and pipings for proper tightness
and make sure that there is no leakage.
c)
Checking Nylon tubes for hydraulic oil intake
and drain:
Retighten brass nut if it is loosened and
leakage is noticed around. If the leakage
continues after retightening, replace the
Nylon tube, nut and sleeve with a set of new
ones.
d)
Check oil tank for proper oil level and see if
the hydraulic oil has not been whitened or
emulsified.
Its whitish color means aeration in pump.
Re-tighten piping and correct the level of oil.
Emulsification means water in the hydraulic
oil. Replace the oil.
a)
Oil filter replacement (Fig.22)
Initial replacement: After 25 hours of operation
Thereafter: In every 500 hours of operation
CAUTION: Use genuine Mikasa filter paper
with 10 microns only. Replace it if suction
resistance has exceeded 254mmHg. (at
operating temperature of 60 degrees C)
b)
Hydraulic oil replacement
Though it depends on load, normally it should
be replaced in every 1,000 to 1,500 hours of
operation. Remove drain plug off oil tank and
hose joint to drain old oil before refilling it with
25 liters of recommended oil. Use care not to
allow dust, foreign matter or water to enter.
CAUTION: Dispose of the oil which pulled out
as the appropriate waste done regulations of.
Recommended wear resistant hydraulic oil:
Viscosity: ISO VG32 equivalent, for cold
region
ISO VG46 or 56 equivalent, for general
and warm region
(At the factory shipment, machine is filled with
Shell Tellus 46.)

Installing the Nylon tube (Fig.23)
●
Insert nut and sleeve to the Nylon tube.
●
Nylon tube should extend from sleeve end by
about 10mm.
●
Insert the Nylon tube straight all the way into
connection of the joint.
●
With the Nylon tube thus inserted, tighten nut
fully with fingers. Then, tighten it further with
wrench to leave 1 -1.5cm of thread of joint
remaining.
(Tightening torque: 100 -140kg-cm)
These are the two points to be carefully
watched during replacement work.
CAUTION:
●
Watch for insufficient depth of insertion
for sleeve and Nylon tube into joint.
●
Watch for insufficient tightening of nut.
