OPERATION
PRE-OPERATION PROCEDURES
CHECK THE POWER SOURCE
1.Using a calibrated flowmeter and pressure guage, check
that the hydraulic power source develops a flow 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 thought No.
4 sign post, 2-1/2 inch square and up to 2-5/8 inch diame-
ter round post without requiring adapters. If you are driving
one of these types of post, orient the post into the tightest
fit 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 fittings or quick disconnects. It is a good practice
to connect return hoses first and disconnect 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 flow 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 in-
crease inside the hoses may make them difficult 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 firmly 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, pre-
heat the hydraulic fluid at low engine speed. When using
the normally recommended fluid, fluid temperature should
be at or above 50°F/10°C (400ssu/82 centistrokes) before
use.
Damage to the hydraulic system or post driver can result
from use with fluid that is too viscous or thick.

11
ACCUMULATOR TESTING PROCEDURE
To check or charge the accumulator the following equip-
ment is required:
Accumulator tester (Part Number 02835).
Charging kit assembly (Part Number 31254) (includes a
regulator, hose and fittings).
NITROGEN bottle with an 800 psi/56 bar minimum charge.
A. Remove the charging valve plug from the post driver.
B. Holding the chuck end of Stanley tester (Part Number
02835), turn the gauge fully counter-clockwise to ensure
the stem inside the chuck is completely retracted.
C. Thread the tester onto the charging valve of the
tool accumulator, (Do not advance the guage-end into the
chuck end. Turn as a unit.) Seat the chuck on the accumu-
lator charging valve and hand tighten only.
D. Advance the valve stem by turning the guage-end clock-
wise until pressure is read on the guage (charging pressure
should be 500-700 psi/34-38 bar).
E. If pressure is OK unscrew the gauge-end from the chuck
to retract the stem, then unscrew the entire tester assem-
bly from the tool accumulator charging valve. If pressure is
low, charge the accumulator as described in the following
section.
F. Install the charging valve cap (or plug).
CHARGING THE ACCUMULATOR
ACCUMULATOR CHARGING PROCEDURE
A. Perform steps A through D of the accumulator
testing procedure above.
B. 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.
C. Adjust the regulator to the charging pressure of 600
psi/42 bar.
Note:
It may be necessary to set the regulator at 650 to 700
psi/45-48 bar to overcome any pressure drop through
the charging system.
D. Open the valve on the charging assembly hose.
E. 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 charg-
ing valve.
F. 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.
G. Replace the o-ring plug.

EQUIPMENT PROTECTION & 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 circuit flow. 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 flow (see Specifications) in this manual for correct flow 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.
In addition to the Safety
Precautions in this manual,
observe the following for
equipment protection and
care.
