Symptom Explanation/Procedure
Post lodged in the
driver
In the event that a driven post ares and becomes lodged within the chuck, follow these steps:
1. Turn engine off. Remove the four 5/16” lower body bolts and separate the lower body casting from the driver body.
2. Slide the lower body casting down the post to expose the ared top of the post. With the proper cutting tool for the type
of post, cut through the post below the ared portion.
3. Once the ared portion is removed, slide the lower body casting off the post and reassemble it to the driver. Please
follow bolt tightening procedure and use threadlocker.
Recommendation: Do not use “thin-wall” or light gauge round post with the Fence Pro™. It is very likely to flare
this type of post at full throttle.
Drives post slow
or sluggish engine
performance:
Typically this is resulting from improper driver storage or over-lling the oil causing the oil to seep into the combustion
chamber. Position the driver vertically, remove the dipstick to check oil level. (See page 6) If you need to remove some oil,
dispose of it properly. If oil is at proper level, follow the procedure listed in “Pull-start is frozen or hard to pull.”
Pull-start is frozen
or hard to pull:
This typically results from oil seeping into the combustion chamber from improper driver storage or overlling the oil reservoir of the en-
gine. Remove spark plug and pull hand grip several times until it pulls freely. Replace the spark plug. Check the oil level in oil reservoir
to ensure proper level (page 6). Follow starting procedure. It is not unusual, for blue smoke to be emitted from the engine, let the engine
run until smoke clears.
Proper Storage: Do not lay horizontally on the driver side or resting on the engine. If the unit cannot be stored securely in the upright position, place the
chuck on a at surface, leaning toward the engine side until it is supported by the shroud and chuck. Position the driver on an angle with
the top handle at the topmost point.

Do not lend or rent
your post driver with-
out the instruction manuals. Be sure that
anyone using it understands the informa-
tion contained in these manuals.
Do not use this post
driver for any purpose
other than driving posts into the ground.
Misuse may result in personal injury or
property damage, including damage to the
machine.
Minors should never
be allowed to use this
power tool. Bystanders, especially chil-
dren, and animals should not be allowed in
the area where it is in use. Any bystanders
or crew without proper safety equipment
should keep a distance or 20 feet (6.00m)
from the driver when it is in operation.
NEVER let your
power tool run unat-
tended. When it is not in use, shut it o
and make sure that unauthorized persons
do not use it.
Do not operate this
post driver unless the
operator is wearing safety glasses, safety
shoes, hearing protection, gloves or any
other safety equipment advised by, ANSI,
NIOSH, OSHA, or any other safety
regulatory agency, or the employer or the
owner of this post driver.
Hearing protection is required as the
post driver emits noise at 100 dB level.
Bystanders should, at a minimum, wear
safety glasses and hearing protection while
in the presence of this power tool during
operation. If not wearing protective gear,
bystanders should keep a distance of 20
feet (6 m) from the post driver while in
operation.
Prolonged use of a
power tool (or other
machines) exposing the operator to vibra-
tions may produce white nger disease
(Raynaud’s phenomenon) or carpal tunnel
syndrome. These conditions reduce the
hand’s ability to feel and regulate tem-
perature, produce numbness and burning
sensations and may cause nerve and circu-
lation damage and tissue necrosis.
Not all factors contributing to white nger
disease are known, but cold weather,
smoking and diseases or physical condi-
tions that aect blood vessels and blood
transport, as well as high vibration levels
and long periods of exposure to vibration
are mentioned as factors in the develop-
ment of white nger disease. In order to
reduce the risk of white nger disease and
carpal tunnel syndrome, please note the
following:
• The Fence Pro™has been designed with
Rhino®CIS™anti-vibration handles to
reduce the transmission of vibrations
created by the machine to the opera-
tor’s hands. An anti-vibration system is
recommended for those persons using
power tools on a regular or sustained
basis.
• The handle opposite the throttle handle
has been tted with an EPDM foam
grip further dampening vibrations.
• Wear gloves and keep your hands warm.

FORE USING YOUR POST DRIVER
Visually inspect your Fence Pro™Post
Driver before use. The interior of the
chuck tube should be checked for obstruc-
tions, damage or wear to the chuck tube
and anvil inside. The outer surfaces of the
driver should also be inspected for any
defects. Do not use the Fence Pro™if there
is any damage or wear until the damage or
wear is corrected and repaired.
Check all uid levels, i.e. engine oil and
fuel and ll as needed as per manufac-
turer’s specications. (Fig. 1)
Proper oil level is essential
to the proper operation of

OPERATING INSTRUCTIONS

Lock the throttle by depressing the trigger
and while the trigger is depressed, push in
the button next to the thumb switch. Hold
the button in and release the trigger. The
throttle is now in the high idle position
(Fig 2).
To start a WARM engine, leave the choke
lever in the OPEN position and do not
lock the throttle into the high idle position.
Press the priming bulb repeatedly until
fuel can be seen in the clear-plastic fuel
return tube (Fig 4).
Slide thumb switch on throttle handle
down or into the ON position.
Grasp the starter grip lightly until you
feel resistance, then pull briskly in the
direction of the arrow as shown in Fig. 5.
Return the starter grip gently.
Do not extend the
starter rope to its full
length as it can cause damage the recoil
mechanism.
An operator should
never wrap the starter
rope around their hand. This will cause
serious injury.
Do not allow the starter grip
to snap back against the
engine. Return it gently to prevent
damage to the starter.
If the choke lever was moved to the
CLOSED position to start the engine,
gradually move it to the open position
as the engine warms up. As the engine
warms up also release the high idle lock
by slightly depressing the trigger and then
immediately releasing it. Use caution as to
not engage the clutch. Dry-Firing (running
the post driver without striking a post)
will shorten the life of the post driver and
could cause damage.

OPERATING INSTRUCTIONS

Hot Restart
If the engine is operated at higher ambient
temperatures, then turned o and allowed
to sit for a short time, it may not restart on
the rst pull. If necessary, use the follow-
ing procedure: Failure to follow instruc-
tions can result in personal injury.
IMPORTANT
SAFETY
PRECAUTION
Turn the engine switch to the OFF position
before performing the following proce-
dure. This will prevent the engine for start-
ing and running at maximum speed when
the throttle is in the MAX. speed position.
If the engine starts with the throttle in the
MAX. speed position, the post driver will
operate at maximum power. This may
result in personal injury and damage to the
post driver.
1. Turn the engine switch on the post
driver to the OFF position.
2. Move the choke lever to the OPEN
position.
3. Hold the throttle in the MAX speed
position.
4. Pull the starter grip 3 to 5 times.
Follow the STARTING THE ENGINE
procedure on the previous page and start
the engine with the choke lever in the
OPEN position.
Driving A Post:
Holding the post driver with your left
hand on the foam grip and your right hand
on the throttle will position the driver to
direct the engine exhaust away from the
operator (Fig 6) (See Exhaust Warning).
Insert a post into the Fence Pro™making
sure the end of the post to be driven is in
the correct location on the ground. (Fig. 7)
Position the driver aligned and centered to
the post. If not aligned properly, damage
could be caused to the driver or the post.
Apply steady downward pressure to the
handles and apply enough throttle to
engage the clutch and hammer.
Once you are condent that the post is
driving straight, apply full throttle to the
driver until the post is driven to the desired
depth.
Release the trigger dropping the engine
RPM back to idle before removing from

the post. When the engine has returned to
idle, proceed to the next post repeating the
previous method of driving a post.
Installing a Chuck Adapter
Chuck Size: A chuck or chuck adapter
that is too large for the post being driven
may damage the driver and may batter
the end of the post. Using the appropri-
ate chuck adapter will align the post to
optimum striking position. This prevents
damage to the driver. See the chart below
to specify the appropriate adapter for your
application. Chucks and chuck adapt-
ers wear out and should be replaced as
needed. Inspect your driver’s chuck and
chuck adapters frequently.
The Rhino®Fence Pro™equipped with the
Rhino®Chuck-Lok™Adapter System. It is
comprised of a master chuck, the locking
nut and two-piece adapters.
ALWAYS HAVE
THE LOCKING
NUT IN PLACE WHEN DRIVING
POSTS: The Chuck-Lok™locking nut
should always be tightened onto the
master chuck to protect the chuck threads,
even when not using an adapter. Failure
to do so exposes the chuck to possible
damage.
The two-piece adapter design is a solu-
tion for the occasional ared post. Should
a post are and lodge inside the chuck
when using the adapter, in most cases the
operator can loosen the locking nut letting
it slide down the post, then lift the driver
o the post. The operator can quickly
re-insert the adapter, secure them with the
locking nut and resume driving posts. See
Fig. 8 for steps for installing Chuck-Lok™
adapters.

Servicing Crankshaft and Piston
Lubrication
The crankcase cover(p/n 300132) is
designed for easy, “no tool” inspection
and maintenance (Fig. 9). To remove the
cover, grip it tightly with your hand and
twist it left (counter-clockwise.) Use cau-
tion not to lose or damage the O-ring Seal
(p/n 301617).
DO NOT USE A
HAMMER OR
WRENCHES TO
LOOSEN THE COVER AS IT MAY
CAUSE DAMAGE TO THE DRIVER.
Visually inspect the color and amount
of Rhino®Pro Series Lubricant inside
the crankcase. There should be a ring of
Rhino®Pro Series Lubricant collected to
the wall inside the crankcase. Should the
depth of the ring from the wall inward
measure 1/8" (3 mm) or less (Fig. 10) this
indicates the Lubricant is low. The maxi-
mum level should not be more than 1/4" (6
mm). If the amount of Lubricant appears
to be low, add a small amount of Rhino®
Pro Series Lubricant. Use only Rhino®Pro
Series Lubricant (p/n 300500.)

SERVICE INSTRUCTIONS

DO NOT OVER-
FILL RHINO®PRO
SERIES LUBRICANT AS IT CAN
DAMAGE THE DRIVER AND THE
HONDA ENGINE.
If the Rhino®Pro Series Lubricant is
discolored, very dark or black, the post
driver will need further maintenance. This
is detailed in the section titled “Service of
the Hammer and Anvil.”
In the event of complete removal of old
Lubricant and adding fresh Lubricant (Fig.
11) rotate the crankshaft with connect-
ing rod and crank pin until the crank pin
is in the 12:00 o'lock position, then add
Rhino®Pro Series Lubricant (p/n 300500).
The level of Rhino®Pro Series Lubricant
should be to the bottom of the crank pin
head. When the required service has been
performed in the crankcase, inspect the
o-ring seal and replace it on the crankcase
cover. Position the crankcase cover on
the Fence Pro™body carefully to start the
threads and once in the thread groove,
with your hand twist to the right (clock-
wise) until it is securely in contact with
the post driver body.
HAND TIGHTEN
ONLY. DO NOT
OVERTIGHTEN. Do not use tools,
such as a hammer or wrench, to tighten
the crankcase cover as it will damage the
driver.
Service of the Hammer and Anvil
The tools required for servicing the ham-
mer and anvil are, a 9/64" hex wrench, a
1/4" hex wrench, a 7/8" deep well socket
with handle, a torque wrench that reads
in inch/pounds (Nm), threadlocker primer
and threadlocker.
Remove the four (4) bolts (p/n 300702-4)
in the bottom of the lower driver body (p/n
301034). Use caution as the handle tubes
(p/n 300232) have anti-vibration springs
(p/n 610010-4) installed and they are
under tension. When the lower driver body
is removed, it should appear as shown
in Fig. 12. The anvil o-ring retainer (p/n
301110) will sometimes be removed with
the lower driver body or remain in place.
Remove the anvil o-ring cup (p/n 301090)
and the anvil (p/n 301160). This can be

accomplished by pushing a 1" dowel rod
or hammer handle into the chuck tube
from the opposite side. When the parts
are removed, note the order of assem-
bly, position of large retainer radius,
and disassemble for inspection. Check the
anvil for any wear. The anvil o-ring (p/n
301616) should be replaced at this time.
Clean the anvil and carefully replace the
anvil o-ring. Fig 13 shows an anvil with
the o-ring in place.
Remove the large retainer o-ring seals
(p/n 301614-2) and the large retainer (p/n
301100) from the anvil o-ring cup. Inspect
the large retainer. The large retainer o-
ring seals should be replaced at this time.
Replace the large retainer if there are any
signs of damage or excessive wear.
The anvil o-ring retainer can be removed
from the end of the cylinder in the post
driver body (p/n 301015) by hand. Use
caution as it can become sharp with use
of the driver. Remove the hammer (p/n
301080), piston and connecting rod
(p/n 301075) by removing the crank pin
(p/n 300050). Access to the crank pin
is achieved by removing the crankcase
cover, which is described in the section
titled “Servicing Crankshaft and Piston
Lubrication” shown in the previous pages
of this manual. Remove the crank pin us-
ing the 7/8" deep well socket.
THE CRANK PIN
HAS LEFT-HAND
THREADS.
Use caution holding the connecting rod
and crankshaft (p/n 300040). The connect-
ing rod and crankshaft can be damaged.
Use a small wood or plastic block to keep
the crankshaft from rotating. When the
crank pin is removed, the piston, con-
necting rod, hammer can be removed by
pushing the connecting rod down into the
cylinder until it can be removed from the
bottom of the post driver body. Note orien-
tation of the hammer. The small end of the
hammer is toward the anvil as shown in
Fig. 14. Clean and inspect the hammer for
damage or excessive wear. The hammer
o-ring Seal should be replaced at this time.
Clean and inspect the piston and con-
necting rod. Insert the crank pin into the
bearing on the connecting rod. If there
is excessive play between the two, the
connecting rod and piston assembly and
possibly the crank pin should be replaced.
Check the movement in the bearing in
the piston side. If there is excessive play
the connecting rod and piston assembly
should be replaced. The piston o-ring seal

Clean and inspect the chuck tube and low-
er driver body assembly (p/n 301034) for
any damage or excessive wear. Replace
if necessary. Lubricate chuck tube with
Rhino®Pro Series Lubricant. Lubricate the
anvil with Rhino®Pro Series Lubricant.
Insert the anvil with new anvil o-ring into
chuck tube, making certain that the anvil is
seated into the chuck tube. Insert the anvil
o-ring cup into the chuck tube. Replace the
chuck tube o-ring (p/n 300608) and insert
the chuck tube o-ring onto the chuck tube.
It should look like Fig. 17.
Remove the handle tubes (p/n 300232)
from the handle cups and remove and
clean and lubricate with Rhino®Pro
Series Lubricant all four (4) anti-vibration
springs (p/n 60010-4.) Check all handle
cups for wear. Clean and lubricate the
upper and lower cups the handle tubes
t into with a small amount of Rhino®
Pro Series Lubricant (p/n 300500). Insert
the anti-vibration springs into the handle
tubes.Assemble the handle tubes into the
upper handle cups. Insert the chuck tube
into the post driver body, taking care to
insert the handle tubes into the handle
cups on the lower driver body. When parts
are inserted in the proper position, there
will be resistance from the anti-vibration
springs to seat the lower driver body on
to the post driver body. This is normal.
Follow the threadlocker procedure on
page 14 to prepare the bolts. Insert and
hand thread the four (4) lower body bolts
through the lower driver body into the
post driver body. Use a 1/4” hex wrench
to tighten the bolts in a star pattern until
the lower driver body is seated on the post
driver body. Check for any misalignment
or binding when joining the parts.
DO NOT USE EXCESSIVE FORCE.
Using a torque wrench set to 132 lb/in
(14.9 Nm) for stainless bolts or 251 lb/in
(28.4 Nm) for black oxide bolts, tighten to
the correct torque. Perform a visual check
of the post driver. Reconnect the spark
plug wire to the spark plug. Check that the
engine has the proper amount of oil. Start
the engine using the proper procedure and
test the post driver.
