The LGRD requires an oil flow of 25-30 l.p.m. and then
works at a pressure of 105-125 bar.
Disconnecting the ground rod driver
WARNING
Hydraulic oil at pressure can injure you. Follow
the instructions below for connecting the hoses.
1 Stop the hydraulic supply.
2
Disconnect the hoses by pulling up the knurled
locking rings and pulling up the couplings. Fit blanking
caps to the hoses.
Hydraulic hoses
For connecting the ground rod driver the hydraulic hose
shall be approved for a working pressure of at least 140
bar and have a ½" inner diameter. To resist exterior
wear and tear we recommend using a 2-layer hydraulic
hose.
The connection on the ground rod driver marked with a
P (pump) is the entry point for oil, and that marked with
a T (tank) is the exit point.
Quick release couplings
In the original, hydraulic hoses are fitted with
Flat-Face quick release couplings.
This kind of quick release coupling is stronger and
easier to clean. The quick release couplings are fitted
so that the male connection supplies the oil and the
female connection receives the oil.
Quick release couplings shall be approved for a
minimum 140 bar working pressure.
This section is intended as a
guide to using the ground rod
driver
WARNING
Never lean against the ground rod driver in order not
to loose foothold, if the rod should break by accident,
or if the rod suddenly sinks.
WARNING
Never rest the rod in a driver on your foot or
against your body.

WARNING
Please read the maintenance
instructions carefully before using the
hydraulic ground rod driver for the first
time.
When working in some materials
particles can fly. Make sure no one
else is within the work area.
Use recommended protective clothing
and equipment to protect yourself
from flying particles.
Stop the hydraulic power source
before change the rod.
Disconnect the hydraulic power
source before the ground rod driver
is serviced.
Always use rods with suitable
dimensions for the ground rod
driver.
Rods that not fit well in the driver
during driving can cause injury. Never
use rods that are much worn or are
damaged.
Always
wear
protective
protective footwear and ear protectors
when using the ground rod driver.
CAUTION
Do not operate the LGRD without pressure
being applied e.g. Do not press the remote
control valve (RC) on the LGRD in the air.
Such
repeated action
damage to the LGRD. If the energy supply
to the LGRD is interrupted, release the
remote control valve (RC) immediately to
prevent damage.
