Choice of ground rod driver
The A/C range of the LGRD is a heavy-duty,
hydraulically
powered
designed for driving ground rods of various
lengths. The high power-to-weight ratio and low
vibration reduce operator fatigue and increase
productivity. Included is a remote double-acting
operating valve that allows operation on either
open-center
or
closed-center
systems. The LGRD-RV 25 can drive rods up to
25 mm (1") in diameter. The LGRD-RV16
accommodates rods up to16 mm (0.625") in
diameter.
Year of manufacture: See the ID-tag.
Correct working methods
Note:
Low/High
Temperatures. In
conditions, warm up the ground rod driver by
light use for a few minutes before starting work.
1. Start the power source.
Note: Allow the power source to run for a few
minutes to warm the hydraulic fluid.
2. Remove the protective caps from the quick -
release couplings.
3. Clean the quick-release couplings if needed
and connect the tail-hoses to the extension
hoses of the power source (see operating
manual of the power source).
4. Slide the ground rod into the LGRD as shown.
5. Lift the ground rod and driver to a vertical position
as shown. For long and heavy rods, two persons
may be required.

6. To start the tool, move the control spool on the
remote control valve to the ON position. When the
LGRD is within reach, grasp the handles.
7 When driving, make sure you are able to keep safely
balanced. Keep arms and legs clear of the rod, if a rod
breaks during operation the ground rod driver with a
projecting broken shank will suddenly drop.
8 Avoid activating the ground rod driver when it is
removed from the rod and ground. This will lead to
increased hydraulic oil temperatures and seal wear.
9 DO NOT invert the ground rod driver without first
isolating the hydraulic supply.
11 Do not continue to work if the hoses vibrate
abnormally.
12 Investigate the contents of the material in which you
are going to work. Look out for hidden cables and
pipes, e.g. electricity, telephone, water, gas, or sewage
lines.
13 If you suspect that the rod has struck a hidden
object, stop the machine immediately. Make sure there
is no danger before continuing with the work.
14 Only use the machine for the jobs for which it is
intended.
Be alert
Always concentrate on what you are doing. Use
common sense. Never operate the machine when you
are tired or under the influence of drugs, alcohol or
other substances which might affect your vision,
reaction ability or judgments.
