2-3. Periodic Inspection List
Fig. 2-2
Note:
When the machine is overhauled, replace the parts referring to the
above list.
2-4. Appling Oil and Grease
When replacing or assembling the parts, use oil and grease while
referring to the following.
On Oil
• Be sure to use the specified grease only. (If oil of different viscosity
is used, it can cause various troubles.)
Oil: Part No. 7-661-018-18
(Mitsubishi diamond oil hydro fluid NT-68)
• The oil used for bearings must not contain any dust or other
materials, otherwise excessive abrasion and seizure of the bearing
could occur.
• A drop of oil means the amount of oil as shown in the illustration
in the right, which is the amount that is attracted to the top of a
rod of 2 mm diameter.
On Grease
• Be sure to use the specified grease only. (If oil of different viscosity
is used, it can cause various troubles.)
Floil grease: Part No. 7-662-001-39
• Be sure to use grease into which dust is not mixed.
• The amount of grease is 1 to 1.5 mm diameter in length.
