REQUIREME TS
a) Mounting Vibrators
See figure line art drawings for illustrations of
item numbers listed in parenthesis.
Angle bracket mounted vibrators are intended
to be mounted on a round bar having an
outside diameter of 2” to 2-7/8”. Generally
the vibrator tip should be angled downward 15
to 30 degrees. Attach the top clamp (23)
around the mounting bar and tighten the two
bolts (24), nuts (20) and lock washers (19).
Straight bracket mounted vibrators (page 9)
should be mounted with two isolators.
b) Hydraulic Hose Connection
The hydraulic hoses exiting the vibrator are
supplied with quick disconnects. Normally
the male quick disconnect is attached to the
pressure line, but this can vary. The smaller
diameter hose is the pressure. Always ensure
that these hoses are attached accordingly or
the oil seal in the hydraulic motor will fail
very quickly.
THE SEAL O THE HYDRAULIC
MOTOR WILL FAIL QUICKLY IF THE
HOSES ARE IMPROPERLY
CO
ECTED.

c) Oil filtration
The hydraulic oil must be properly filtered to
ensure proper operation and to prevent wear
and damage due to contaminates.
IT IS IMPORTA T THAT THE
HYDRAULIC FLUID BE PROPERLY
FILTERED TO 10 MICRO ABSOLUTE
(ISO 17/13 FLUID CLEA LI ESS). OIL
THAT IS OT PROPERLY FILTERED
MAY CAUSE DAMAGE TO THE
HYDRAULIC MOTOR.
d) Vibrator Performance and Oil Supply
Oil Pressure
Oil pressure will vary depending on oil tem-
perature, flow rate, oil viscosity and the
amount of hose connected between manifold
and vibrator. A vibrator in good condition
should operate with a pressure of 700 PSI to
1200 PSI at 4 GPM and 140° F.
Temperature
The hydraulic oil temperature should be
maintained between 100° F and 180° F
with 140° F being optimum.
U DER 100°F, EXCESSIVE PRESSURE
IS REQUIRED TO OPERATE THE
VIBRATOR AT ORMAL SPEEDS.
TEMPERATURES ABOVE 196° F
