PREOPERATION
PROCEDURES
CHECK HYDRAULIC POWER
SOURCE
1. Using a calibrated fl owmeter and pressure
gauge, check that the hydraulic power source de-
velops a fl ow of 3-9 gpm/11-34 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/145-155 bar minimum.
CHECK TOOL
1. There should be no signs of leaks.
2. The tool should be clean, with all fi ttings and
fasteners tight.
CONNECT 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 fi ttings or quick disconnects. It
is a good practice to connect the return hose fi rst
and disconnect it last to minimize or avoid trapped
pressure within the tool.
3. Observe fl ow indicators stamped on hose cou-
plers to be sure that oil will fl ow in the proper direc-
tion. The female coupler is the inlet coupler.
NOTE:
The pressure increase in uncoupled
hoses left in the sun may result in making them

PREPARATION FOR INITIAL
USE
Each unit as shipped has no special unpacking or
assembly requirements prior to usage. Inspection
to assure the unit was not damaged in shipping
and does not contain packing debris is all that is
required.
OPERATION
diffi cult to connect. When possible, connect
the free ends of operating hoses together.
4. Observe all safety precautions.
5. Move the hydraulic circuit control valve to the
“ON” position to operate the tool.
1. Observe all safety precautions.
2. For fl anged posts, position the base weldment
on a fl at surface with the post engaged in the jaws
of the tool.
3. For solid or square posts, position the base
weldment on a fl at surface and wrap a chain
around the post. Place the chain in the slots on the
post puller frame.
4. Actuate the control lever from the “NEUTRAL”
position to the “UP” position until the post raises
approximately eight inches.
5. Move the control lever from the “UP” position
past the “NEUTRAL” position to the “DOWN” posi-
tion. This releases the jaws (or chain) from the post
and lowers the lift frame weldment down to the
base weldment (bottom of post).
6. Repeat steps one through fi ve until the post is
fully removed.
If the post puller is to be used during cold weather,
preheat the hydraulic fl uid at low engine speed.
When using the normally recommended fl uids,
fl uid temperature should be at or above 50 °F/10°C
(400 ssu/82 centistokes) before use.
Damage to the hydraulic system or post puller can
result from use with fl uid that is too viscous or thick.
