4. RULES FOR CONDUCTING SERVICE WORK
3
In order to avoid deficient reassembly, know normal status of installation before removing or disasem-
bling any part. Level check or replacement of vibrator oil should be carried out on level ground.
Each time disassembly is made involving oil seal, gasket, packing, o-ring, lock washer or the like,be
sure to replace them with new ones.
Mating surfaces of vibrator case and compaction plate should be sealed with liquid gasket (Clean and
de-grease the mating surfaces thoroughly).
For tightening bolts and nuts, use the specified standard torque and bonding agent (Loctite or the like).
For such bolts and nuts that are not specified, see Table of Tightening Torque. (Before coating with
Loctite, clean the screw with gasoline or thinner.)
NOTE:
All the screw in use with this machine are right handed.
Disassembly work should be conducted where it is free from dust.
Where bonding agent such as Loctite has been in use and screw is hard to loosen, heat it with torch
lamp or the like. Such heated bolt must be replaced with new one, which is of high-tension type as
specified.
Use proper tool in proper manner.
