MODEL 66-80 VIBRATORY DRIVER/EXTRACTOR
IV. MAINTENANCE AND ADJUSTMENTS
A. GENERAL
Preventive maintenance includes normal servicing that will keep the vibratory
driver, clamp and power unit 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.
Lubrication is an essential part of preventative maintenance, controlling to a great
extent the useful life of the unit. Different lubricants are needed and some
components in the unit require more frequent lubrication than others. Therefore, it
is important that the instructions regarding types of lubricants and frequency of
their applications 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 unit.
Thoroughly clean all lubrication fittings, caps, filler and level plugs and their
surrounding surfaces before servicing. Prevent dirt from entering with lubricants
and coolants. 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.
B. DAILY
1. Check the entire unit prior to and during set-up each day or at the beginning of
each shift.
2. Prior to starting the power unit or at the beginning of each shift, check the
following items:
a. Visibly inspect all bolts, nuts and screws including the bolts fastening the
hydraulic clamp to the vibration case to insure they are tight.
IMPORTANT: Vibration loosens bolts. Check carefully.
b. Tighten bolts holding gripping jaws in hydraulic clamp.
c. Grease plunger in hydraulic clamp with any good multi-purpose grease.
d. Check the oil level in the vibration case and add oil if required. The oil
level should be in the middle of the sight glass. Change oil if milky or
contaminated. DO NOT OVERFILL
e. Check the oil level in the hydraulic reservoir and refill if necessary.
CAUTION: It is absolutely imperative that no dirt or other impurities be
permitted to contaminate the hydraulic oil. Any contamination will
drastically shorten the life of the high-pressure hydraulic system.
