MAINTENANCE AND ADJUSTMENTS
A.
GENERAL
Preventive maintenance includes normal servicing that will keep the hydraulic
hammer in peak operating condition and prevent unnecessary trouble from
developing. This servicing consists of periodic lubrication and inspection of the
moving parts and accessories of the unit. J&M equipment is engineered to provide
reliable operation and a long service life under normal operating conditions.
Equipment reliability and service life can be improved by following the maintenance
procedures in this manual.
Lubrication is an essential part of preventative maintenance, controlling to a great
extent the useful life of the hammer. Different lubricants are needed and some
components require more frequent lubrication than others. Therefore, it is
necessary that the instructions regarding types of lubricants and frequency of their
application be closely followed.
To prevent minor irregularities from developing into serious conditions that might
involve shut-down and major repair, several other services or inspections are
recommended for the same intervals as the periodic lubrications. The purpose of
these services or inspections is to assure the uninterrupted operation of the
hammer. Thoroughly clean all lubrication fittings and caps and their surrounding
surfaces before servicing. Prevent dirt from entering with lubricants and fuel.
The intervals given in the schedule are based on normal operation. Perform these
services, inspections, etc. more often as needed for operation under abnormal or
severe conditions.
