NT 206-A00 10.11 Hydrive e
3. INSTALLATION (continued)
There are 2 versions of the HYDRIVE 2010, standard version
and selector valve version. (NOTE : Use a remote on / off
valve on hydraulic systems using the hydrive 2010 without
the selector valve).
The selector version features a manually operated spool
valve so that the high pressure oil (from the hydraulic pump)
can be switched between two possible hydraulic motors
(Motor 1 & Motor 2). The valve can also be set to neutral posi-
tion with the system unloaded, and the oil returning back to
the tank.
The selector version is designed for tanker applications
where both a compressor and pump may be installed on a
vehicle but operated separately. HYDRIVES are NOT suita-
ble for use with hydraulic cylinders.
The selector valve is NOT available for the HYDRIVE 2020
model.
The HYDRIVE 2010 is not designed for use with 2 motors
running simultaneously unless the system is designed to
allow multi motor operation.

NOTES
THE DRIVEN MACHINE, PUMP OR COMPRESSOR, WILL START AUTO-
MATICALLY WHEN THE HYDRAULIC PUMP IS ENGAGED UNLESS A
REMOTE ON/OFF CONTROL VALVE IS INSTALLED IN THE SYSTEM.
A cold start bypass protects the cooler and quickly warms the
oil to its normal working temperature.
