16. LUBRICATION TO CRANE
Lubricate according to “Lubrication chart”
and keep the following instructions in mind
when carrying out lubrication.
Precaution when
carrying out lubrica-
tion
WARNING
• Do not carry out maintenance and inspection while temperature of
hydraulic oil is still high.
• Be sure to stop the engine to carry out lubrication.
• Temperature if both hydraulic and gear oils is high immediately after
crane operation so that accumulated high pressure still remains inside.
Uncapping the filling port, draining oil, and replacing filter while oil
temperature is high allow the hydraulic and/or gear oils to spout out
and a scald may result.
CAUTION
•
In order to ensure smooth oper-
ation of each part of the crane,
minimum wear, and longer
service life, be sure to supply
lubricant as well as hydraulic oil
which is indispensable to drive
hydraulic equipment.
•
Warranty will not be given, even
if it is within the period to be
applied, for failure to observe
the replacement of lubricant as
specified.
1.
Clean filling ports and grease nipples thor-
oughly before carrying out lubrication.
2.
Always supply new lubricant and prevent
dusts from entering inside.
3.
When supplying grease into each grease
nipple, be sure to inject it until old grease is
forced out of it.
