CAUTIONS WHEN WORKING
When disassembling or assembling
• Clean the machine before disassembly.
• Check the following items and record the results:
a. Model, machine serial number, hour meter.
b. Reason for repair, repair history.
c. Are the filters dirty?
d. The conditions of the fuel and oil.
e. Any damage or looseness to any part?
• Where necessary, draw alignment indicators to avoid
assembly errors. To avoid misconnection, place indi-
cators such as reference tags on pipes.
• Clean all disassembled parts and new parts, arrange
them neatly, and place indicators as necessary.
• Be sure to replace all seals and cotter pins with new
ones.
• Keep those parts that should not come in contact with
water or oil away from those with oil on the surface.
• When installing bearings, bushings and oil seals, a
press tool should be used. If a hammer is used, use a
cushioning material to avoid damage.
• Wipe all joining surfaces clean until there is no dirt or
dust adhering to them.
• Wrap the thread tight with seal tape starting 1 or 2
threads away from the thread end. The tape should be
overlapped by about 10 mm (0.39 in).
When removing/installing the hydraulic unit
• Make sure that the temperature of the hydraulic oil has
dropped and is cool enough to work with.
• To prevent the hydraulic oil from escaping under pres-
sure, release the residual pressure in the piping.
• Be sure to install caps or plugs on all openings in the
hydraulic unit to prevent dirt from getting into the unit
through them.
• The hydraulic oil adhering to the unit is often mistaken
for an oil leak, so wipe off the unit thoroughly.
• Be sure that no damage is caused to the plating on the
rod in the hydraulic cylinder.
• Removal and installation of the hydraulic cylinder
should be done with the rod fully retracted.
• Be sure to bleed the air after installing the hydraulic
cylinder. (
“4. Disassembly and assembly: Cylin-
der”)
• Always bleed the air when hydraulic oil is changed or
a hydraulic device is replaced. (

and assembly: Drive system”)
