4. RULES FOR CONDUCTING SERVICE WORK
1. In order to avoid deficient reassembly, know normal status of installation before removing or
disassembling any part. Level check or replacement of vibrator oil should be carried out on level
ground.
2. 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.
3. Mating surfaces of vibrator case and compaction plate should be sealed with liquid gasket (Clean and
de-grease the mating surfaces thoroughly).
NOTE:
All the screw in use with this machine are right handed.

5. Disassembly work should be conducted where it is free from dust.
6. 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.
7. Use proper tool in proper manner.
8. Remove (-) battery terminal first before disassembling and connect (-) battery terminal lastly.

4. Clean the screw before coating with Loctite. 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.
