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 protective 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 fi ttings, caps, fi ller 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.
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 fl uid level in the hydraulic reservoir and refi ll if necessary.
Vibration loosens bolts - check carefully.
It is absolutely imperative that no dirt or other impurities be permitted
to contaminate the hydraulic fl uid. Any contamination will drastically
shorten the life of the high-pressure hydraulic system.
