5) When coating with adhesive, clean the part and remove all oil and grease, then coat the threaded
portion with 2-3 drops of adhesive.
6) When coating with gasket sealant, clean the surface and remove all oil and grease, check that
there is no dirt or damage, then coat uniformly with gasket sealant.

hydraulic cylinders, pumps, or other hydraulic equipment or piping, always bleed the air from the
hydraulic cylinders as follows:
Start the engine and run at low idling.
(1)
Operate the control lever and actuate the hydraulic cylinder 4-5 times, stopping 100mm before the

actuated to bleed the air.)
After completing this operation, raise the engine speed to the normal operating condition.

If the hydraulic cylinder has been replaced, carry out this procedure before assembling the rod
to the work equipment.
Carry out the same operation on machines that have been in storage for a long time after
completion of repairs.
