GENERAL INFORMATION
Bleeding the hydraulic system
The Operating Temperature references the internal
temperature of the motor. Take into consideration
the following requirements:
•
21°C (70°F) – Operate the Vibro at reduced
speed while below this temperature
•
27°C (80°F) – Ideal working temperature.
•
70°C (158°F) – Avoid going over this Operating
Temperature for improved service life
•
85°C (185°F) – Highest permissible intermittent
Operating Temperature
•
-35°C (-31°F) – Lowest permissible Operating
Temperature
•
60°C (140°F) – Temperature difference between
the motor and the hydraulic fluid
The Operating Temperature may be measured from
the hydraulic fluid returning from the motor. Case
drain fluid temperature will also have an effect.
Operating Temperatures
Bleeding Clamp Hoses
1.
When the vibrator and hydraulic clamp are
shipped with all hoses attached (between
vibrator and clamp and five main hoses
connected to the vibrator), the hoses are
usually full of oil and may be used immediately.
However if any of the clamp hoses are
connected at the job site or if air is present in
hoses they must be bled prior to operation
2. Start and warm up the hydraulic power unit.
3. With the power unit warmed-up and running at
1500 RPM loosen the clamp close hose at the
hydraulic clamp. Turn the clamp switch on the
remote control pendant to close. Wait until only
oil flows from the connection at the hydraulic
clamp. When oil flows without air tighten the
connection.
4. Repeat step 3 with the clamp open line.
5.
After the line has been bled, alternately turn
the clamp switch to close and open to insure
that the clamp is working properly. It may be
necessary to bleed the line more than once.
Filling Vibrator Pressure Hoses
1. Start and warm up the hydraulic power unit.
2. With the engine warmed up and running at
1000RPM turn and hold the vibrator switch in
reverse. The hoses will fill in approximately 5
minutes.
Caution: If vibration begins in the vibrator, stop
immediately and recheck hose connections.
Before operation it is necessary to bring
the power units hydraulic oil to a working
temperature of 80
0F. To start and warm up the
power unit follow the steps below.
1.
On the main control panel turn main power
switch to the on position.
2. Press and hold engine start/stop button
until engine in running. This should only
take a few seconds.
3.
Idle power unit in drive until oil temp is
above 80
0F before doing hard work. Failing
to do so may cause seal failures, leaks and
excessive pressures through the hydraulic
system.
