OPERATION
PRE-OPERATION PROCEDURES
CHECK THE POWER SOURCE
1. Using a calibrated owmeter and pressure gauge,
check that the hydraulic power source develops a
ow of 7–9 gpm/26–34 lpm at 2000 psi/140 bar.
2. Make certain the hydraulic power source is equipped
with a relief valve set to open at 2100–2250 psi/140
bar.
INSTALLING ADAPTERS
1. The post hammer is designed to drive No. 1 through
No. 4 sign post, 2-1/2 inch square and up to 2-5/8
inch diameter round post without requiring adapters.
If you are driving one of these types of post, orient
the post into the tightest t in the post driver foot.
2. If you are driving smaller square or round post, insert the adapter to the post driver foot using two
½-hex head capscrews.
CONNECTING HOSES
1. Wipe all hose couplers with a clean, lint-free cloth
before making connections.
2. Connect the hoses from the hydraulic power source
to the tool ttings or quick disconnects. It is a good
practice to connect return hoses rst and discon-
nect them last to minimize or avoid trapped pressure
within the tool.
3. If hose couplers are used, observe the arrow on the
coupler to ensure that the ow is in the proper direction. The female coupler on the tool hose is the inlet
(pressure) coupler.
4. Move the hydraulic power source On/Off control
valve to the ON position to operate the tool.
NOTE:
If uncoupled hoses are left in the sun, pressure increase inside the hoses may make them difcult to
connect. When possible, connect the free ends of
the operating hoses together.
TOOL OPERATION
1. Observe all safety precautions.
2. Install the appropriate adapter as required.
3. Place the post driver foot rmly on the surface to be
driven.
4. Press the lever assembly on handle to start the post
driver.
NOTE:
On Remote ON/OFF Valve Models Place the post
driver on/off control valve in The ON position to
start the post driver.
NOTE:
Adequate down pressure is very important.
5. When the post is fully set in the ground, release the
lever assembly on handle.
COLD WEATHER OPERATION
If the post hammer is to be used during cold weather,
preheat the hydraulic uid at low engine speed. When
using the normally recommended uid, uid tempera-
ture should be at or above 50°F/10°C (400 ssu/82 centistrokes) before use.
Damage to the hydraulic system or post driver can result
from use with uid that is too viscous or thick.

Val ve
Accumulator Tester (P/N 02835) Location Of C harging Valve
ACCUMULATOR TESTING PROCEDURE
To check or charge the accumulator the following equipment is required:
• Accumulator Tester (Part Number 02835).
• Charging Kit Assembly (P/N 31254); (includes a
regulator, hose and ttings).
• NITROGEN bottle with an 800 psi/56 bar minimum
charge.
1. Remove the charging valve plug from the post driver.
2. Holding the chuck end of Stanley tester (P/N 02835),
turn the gauge fully counter-clockwise to ensure the
stem inside the chuck is completely retracted.
3. Thread the tester onto the charging valve of the tool
accumulator (do not advance the gauge-end into
the chuck end; turn as a unit). Seat the chuck on the
accumulator charging valve and hand tighten only.
4. Advance the valve stem by turning the gauge-end
clockwise until pressure is read on the gauge (charg-
ing pressure should be 500–700 psi/34–38 bar).
5. If pressure is OK unscrew the gauge-end from the
chuck to retract the stem, then unscrew the entire
tester assembly from the tool accumulator charging
valve. If pressure is low, charge the accumulator as
described in the following section.
6. Install the charging valve cap (or plug).
ACCUMULATOR CHARGING PROCEDURE
1. Perform Steps 1 through 4 of the Accumulator Test-
ing Procedure above.
2. Connect the chuck of the charging assembly to
the charging valve on the accumulator tester or, if
preferred, remove the tester from the tool charging
valve and connect the charging assembly chuck directly to the tool charging valve.
3. Adjust the regulator to the charging pressure of 600
psi/42 bar.
NOTE:
It may be necessary to set the regulator at 650–
700 psi/45–48 bar to overcome any pressure drop
through the charging system.
4. Open the valve on the charging assembly hose.
5. When the accumulator is fully charged close the
valve on the charging assembly hose and remove
the charging assembly chuck from the accumulator
tester of tool charging valve.
6. If the accumulator tester has been used, be sure to
turn the gauge-end fully counterclockwise before removing the tester from the charging valve of the tool.
7. Replace the O-ring plug.

TOOL PROTECTION & CARE
NOTICE
In addition to the Safety Precautions found in
this manual, observe the following for equipment
protection and care.
• Make sure all couplers are wiped clean before connection.
• The hydraulic circuit control valve must be in the
OFF position when coupling or uncoupling hydraulic tools. Failure to do so may result in damage to
the quick couplers and cause overheating of the hydraulic system.
• Always store the tool in a clean dry space, safe from
damage or pilferage.
• Make sure the circuit PRESSURE hose (with male
quick disconnect) is connected to the IN port. The
circuit RETURN hose (with female quick disconnect)
is connected to the opposite port. Do not reverse cir-
cuit ow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts
with replacement parts recommended by Stanley
Hydraulic Tools. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated ow (see Specications) in
this manual for correct ow rate and model number.
Rapid failure of the internal seals may result.
• Always keep critical tool markings, such as warning
stickers and tags legible.
• Do not use the tool for applications it was not designed for.
• Tool repair should be performed by experienced
personnel only.
• Make certain that the recommended relief valves
are installed in the pressure side of the system.
• Do not use the tool for applications for which it was
not intended.
