Operation Information
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
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.
