HRD-1 and HRD-58 Hydraulic Ground Rod Drivers
Description
The HRD-1 and HRD-58 Greenlee Utility Ground Rod
Drivers are heavy-duty, hydraulically powered recip-
rocating tools 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 hydraulic systems.
The HRD-1 can drive rods up to 25 mm (1") in
diameter. The HRD-58 accommodates rods up to
16 mm (0.625") in diameter.

IMPORTANT SAFETY INFORMATION
SAFETY
ALERT
SYMBOL
This symbol is used to call your attention to
hazards or unsafe practices which could result in
an injury or property damage. The signal word,
dened below, indicates the severity of the hazard.
The message after the signal word provides infor-
mation for preventing or avoiding the hazard.
Immediate hazards which, if not avoided, WILL
result in severe injury or death.
Hazards which, if not avoided, COULD result in
severe injury or death.
Hazards or unsafe practices which, if not avoided,
MAY result in injury or property damage.
Read and understand all of the
instructions and safety information
in this manual before operating or
servicing this tool.
Failure to observe this warning
could result in severe injury or
death.

IMPORTANT SAFETY INFORMATION
Wear a hard hat when using this
tool.
Failure to observe this warning
could result in serious injury or
death.
Tool and accessory may be hot
during and after operation. Allow to
cool before handling, or handle with
heat-resistant gloves.
Contact with hot surfaces could
result in serious injury.
Electric shock hazard:
This tool is not insulated. When
using this unit near energized
electrical lines:
• Use only certied non- conductive
hoses and proper personal
protective equipment.
• Select and maintain the hydraulic
uid to meet the minimum dielec-
tric standards required by your
safety department.
Failure to observe this warning
could result in severe injury or
death.
Do not disconnect tool, hoses, or ttings while the
power source is running or if the hydraulic uid is
hot. Hot hydraulic uid could cause serious burns.
Do not reverse hydraulic ow. Operation with
hydraulic ow reversed can cause tool malfunc-
tion. Connect the supply (pressure) hose and return
(tank) hose to the proper ports.
Failure to observe this warning could result in
severe injury or death.
Do not change accessories, inspect, adjust or
clean tool when it is connected to a power source.
Accidental startup could result in serious injury or
death.
Serious injury could result if the operator does not
maintain control of the tool.
• Wear slip-proof gloves when operating this tool.
• Maintain a rm grip on the tool, using both hands
at all times.
• Do not lock the trigger in the power-ON position.
Operator cannot stop tool when the trigger is
locked.
Failure to observe these warnings could result in
severe injury or death.
Accumulator is charged with nitrogen under high
pressure. This pressure must be unloaded before
dismounting.
Failure to observe this warning could result in
severe injury or death.

Vibration hazard:
Apply just enough pressure to do the work.
Applying excess pressure to the tool can cause
operator discomfort or temporary numbness.
Failure to observe this precaution may result in
injury.
These tools can weigh more than 25 kg (55 lb)
and
require two persons to lift and transport.
Failure to observe this precaution may result in
injury.
Hydraulic oil can cause skin irritation.
• Handle the tool and hoses with care to prevent
skin contact with hydraulic oil.
• In case of accidental skin contact with hydraulic
oil, wash the affected area immediately to remove
the oil.
Failure to observe these precautions may result in
injury.
• Inspect the hydraulic hoses and couplings every
operating day. Repair or replace if leakage,
cracking, wear, or damage is evident. Damaged
hoses or couplings may fail, resulting in injury or
property damage.
• Use this tool for manufacturer’s intended purpose
only. Use other than that which is described
in this manual may result in injury or property
damage.
• Make sure all bystanders are clear of the work
area when handling, starting, and operating the
tool. Nearby personnel may be injured by ying
or falling debris or by ying parts in the event of a
tool malfunction.
IMPORTANT SAFETY INFORMATION
Procedure for connecting or disconnecting
hydraulic hoses, ttings or components:
1. Move the ow lever on the power source to the
OFF position.
2. Stop the hydraulic power source.
3. Follow the sequence under “Hose
Connections” to prevent pressure buildup. In
case some pressure has built up, loosen hoses,
ttings or components slowly.
Emergency stop procedure:
1. Release the trigger.
2. Shut off the hydraulic power source.
Note: Keep decals clean and legible. Replace decals
when necessary.
When disposing of any components (hydraulic hoses,
hydraulic fluid, worn parts, etc.), do so in accordance
with federal, state, and local laws or ordinances.

• Hydraulic ow: 30 l/min (8 gpm)
• Pressure relief: 160 bar (2300 psi)
• Back pressure: 28 bar (405 psi)
Failure to observe this warning could result in
severe injury or death.
• Optimal performance occurs at maximum ow.
• Maximum hydraulic uid temperature must not
exceed 70 °C (158 °F). A sufcient oil cooling
capacity is needed to limit the hydraulic uid
temperature.
• Hydraulic ow must not exceed 30 l/min (8 gpm).
Install a ow meter in the return line to measure the
rate of hydraulic ow before using the tool.
• Pressure relief valve setting must not exceed
160 bar (2300 psi) at your tool’s maximum ow.

Viscosity Index ...............................................Min. 100
Standard mineral or synthetic oil can be used.
When the tool works continuously, the oil temperature
will steady at a certain level called the oil working
temperature. Depending on the nature of the job and
the cooling capacity of the system, the oil working
temperature will be 20 °C to 40 °C (68 °F to 104 °F)
above the air temperature. At working temperature,
the oil viscosity must be within the ideal area. The
tool may not be operated if the oil viscosity is not
within the allowable area or if the temperature is not
within –20 °C to 70 °C (–4 °F to 158 °F).
The viscosity index expresses the dependence of the
viscosity on the temperature. Thus, a high viscosity
index is preferable so that the oil can be used within
a wide temperature interval.

Typical Setup
Hose Connections
Do not disconnect tool, hoses, or ttings while the
power source is running or if the hydraulic uid is
hot. Hot hydraulic uid could cause serious burns.
The remote valve can be used
on both open-center and
closed-center systems by
adjusting the OC/CC selection
spool.
• For open-center pump
operation, use a at head
screwdriver to turn the spool
counterclockwise until it
backs into the snap ring.
• For closed-center operation, tighten the spool in the
clockwise direction until snug.
When connecting or disconnecting the remote
valve, always ensure that the valve is in the off
position and the system is depressurized.
Failure to observe this warning could result in
severe injury or death.
Connecting Remote Valve
When connecting the remote valve to the system,
connect lines in order as numbered in the diagram
below (1–2–3–4).
Disconnecting Remote Valve
When disconnecting the remote valve, remove lines in
reverse order of the numbering in the diagram below
(4–3–2–1).
