TAKE SAFETY SERIOUSLY

Ranch Pro™Trouble Shooting

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 thread locker solution.

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.” It also is good practice to wipe

clean the engine after use.

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 engine.

Remove spark plug and pull hand grip a 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: When storing your Ranch Pro™ do not lay it 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 the at surface, lean it toward the engine

side until it is supported by the shroud and chuck. This will position the driver on an angle with the top handle at the

topmost point.

INTRODUCTION

The Rhino®Ranch Pro™gas powered

driver is designed to drive fence posts,

ground rod, form pins, and other like items

into the ground. Uses, other than those

intended, can result in injury to the opera-

tor as well as those around the operator.

Damage to the driver and to the surround-

ing area may result as well.

This post driver is intended for use by pro-

fessional installers. Never allow children

to operate this tool.

Most accidents can be prevented if you

follow all instructions in this manual and

on the post driver. The most common haz-

ards are discussed below, along with the

best method to protect yourself and others.

UNDERGROUND

UTILITIES: Driving

a post into an underground utility can be

EXTREMELY DANGEROUS, exposing

the operator and those around to poten-

tially life threatening danger. Damage to

surrounding property can also occur as a

result of a post being driven into an under-

ground utility. Be absolutely certain that

you are aware of all underground utilities

in the area in which you intend to drive

posts. Ensure that a certied locating ser-

vice has identied all underground utilities

prior to beginning your project. Failure to

do so can be catastrophic. Underground

utilities include but are not limited to:

Electric, Gas, Telephone, Water, Sewer,

TV Cable, Lawn Sprinklers, etc.

GASOLINE: Gaso-

line is HIGHLY

FLAMMABLE and EXPLOSIVE. You

can be burned or seriously injured when

handling fuel.

EXHAUST: The ex-

haust from the engine

contains poisonous carbon monoxide gas

that can build up to dangerous levels in

closed areas. Breathing carbon monoxide

can cause unconsciousness or death. Never

run the engine in a closed or even partly

closed area where people may be present.

The engine exhaust

from this product

contains chemicals known to the State of

California to cause cancer, birth defects or

other reproductive harm.

ENGINE

MAINTENANCE:

Improperly maintaining the engine on this

power tool, or failure to correct a problem

before operation, can cause a malfunc-

tion in which you can be seriously hurt or

killed.

In accordance with the engine owner’s

manual, always perform a pre-operation

inspection of the engine before each use

and correct any problem.

DRIVER

MAINTENANCE:

Improperly maintaining the driving

mechanism on this power tool, or failure

to correct a problem before operation, can

cause a malfunction in which you can be

seriously hurt or killed.

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.

NEVER let your

power tool run unat-

tended. When it is not in use, shut it off

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 (6.00m) 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 affect 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:

• Ranch 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.

• Ensure that the EPDM foam and the

spring dampening system are in good

working condition.

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), and threadlocker.

Remove the four (4) bolts (p/n 300702-4)

in the bottom of the lower driver body (p/n

300031). Use caution as the handle tubes

(p/n 301232) 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

300110) will sometimes be removed with

the lower driver body or remain in place.

Remove the anvil o-ring cup (p/n 300090)

and the anvil (p/n 300160). This can be

easily 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 and disas-

semble for inspection. Check the anvil for

any wear. The anvil o-ring (p/n 300606)

should be replaced at this time. Clean the

anvil and carefully replace the anvil o-

ring. (Fig 13).

Remove the large retainer o-ring seals

(p/n 300604-2) and the large retainer (p/n

300100) from the anvil o-ring cup.

Inspect the large retainer. The large retain-

er 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

caution as it can become sharp with use of

the driver.

Remove the hammer (p/n 300080), piston

and connecting rod assembly (p/n 300075)

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 using 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 con-

necting rod and crankshaft can be dam-

aged. Use a small wood or plastic block to

keep the crankshaft from rotating. When

the crank pin is removed, the piston and

connecting rod assembly, hammer can be

removed by pushing the connecting rod

down into the cylinder until it can be re-

moved from the bottom of the post driver

body. Note orientation 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 exces-

sive 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 or side movement 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 (p/n 300600-2) should

be replaced at this time. (See Fig. 15.)

Clean and inspect the cylinder and crank-

case for any damage or wear. Replace any

damaged parts. Lubricate the cylinder,

piston, and connecting rod with Rhino ap-

proved grease (p/n 300500.)

RECOMMENDED

THREADLOCKER

PROCEDURE: Clean any residue from

the bolts and internal bolt threads with

acetone or solvent. Apply threadlocker

primer to the bolt holes and bolt threads

and allow the primer to dry. Follow

with an application of threadlocker to

the bolt hole threads.

ing the crank pin. Insert the connecting

rod, with the piston attached, into the

cylinder. Push the piston up the cylinder

until the bearing in the connection rod

aligns with the threaded hole for the crank

pin. Insert the Crank Pin through the bear-

ing and start the threads into the Crank-

shaft by hand. These are LEFT-HAND

THREADS. Tighten the crank pin using

the 7/8" deep well socket. Torque to 360

inch/pounds (40.6 Nm).

(Fig. 10) Rotate crankshaft with con-

necting rod, piston and crankpin until the

crankpin is in the 12:00 o'clock position.If

grease has been completely removed add

2.75 oz or 81.32 ml of Rhino®Pro Series

Grease or until level with the bottom of

the crankpin head. (See Caution: Do not

overll grease on page 12) Close the

crankcase by placing the crankcase cover

o-ring seal onto the crankcase cover. Place

the crankcase cover onto the post driver

body, start the thread, and twist to the

right (clockwise) with your hand until it is

secure against the post driver body. (See

Caution: Do Not Overtighten on page

12)

Lubricate the cylinder and hammer with

Rhino approved grease (p/n 300500.)

Insert the hammer into the cylinder, taking

note of the small end to the anvil as shown

in Fig. 13. Push the hammer into the

cylinder making room to insert the anvil

o-ring retainer. Apply grease to the anvil

o-ring retainer and place the small end into

the cylinder. The grease should hold it in

place.

Lubricate with grease and assemble the

large retainer and the two (2) large retainer

o-ring seals in the order shown in Fig. 16

and assemble into the anvil o-ring cup.

Insert o-ring into anvil o-ring cup, then

insert large retainer, followed by inserting

the other o-ring.

Clean and inspect the chuck tube (p/n

300156) and lower driver body (p/n

300031) for any damage or excessive

wear. Replace if necessary. Lubricate

chuck tube with grease. Lubricate the

anvil with grease. Insert the anvil with

new anvil o-ring into chuck tube, mak-

ing 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

Remove the handle tubes (p/n 301232)

from the handle cups and remove and

clean and lubricate with grease all four

(4) anti-vibration springs (p/n 610010-4.)

Check all handle cups for wear. Clean and

lubricate the upper and lower cups the

handle tubes t into with a small amount

of grease. 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 resis-

tance 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 13. 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. Torque the lower body bolts to

132 inch/pounds (14.91 Nm).

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.
