RHINO PD-39 User manual

Your Rhino Air Operated Post Driver has only three moving parts, the handle assemblies and the piston which strikes
directly on the post to be driven. Your post driver is very efficient and, with reasonable care and maintenance, will give
you trouble-free service.
It is VERY IMPORTANT to understand that your driver is a very powerful machine; it has to be to drive posts into the
ground.
You must read and understand your post driver operating instructions before using your unit. It is also very important
that you make sure all operators are trained to operate your post driver safely. If you or any operator doesn’t under-
stand any of the instructions, call Rhino collect at [phone] and we will be happy to answer any questions.
WARNING – AVOID SERIOUS INJURY OR DEATH,
READ BEFORE USING YOUR POST DRIVER!
WARNING UNDERGROUND UTILITIES: Be absolutely sure you know where all underground utilities are before
driving so you can avoid hitting them while driving a post into the ground. Utilities include but are
not limited to Electric, Gas, Telephone, Water, Sewer, TV Cable, Lawn Sprinklers, Etc. Hitting an
underground utility could be EXTREMELY DANGEROUS for the operator and others.
WARNING AIR PRESSURE: You must use a Filter-Regulator-Lubricator combination with your Rhino Air
Operated Post Driver. The use of the pressure regulator is required for safety. Set the pressure regu-
lator at 90 PSI (6.4 kg/cm2). Higher air pressures will not make your driver perform better. High air
pressure could cause your post driver to lift off and fall from the post causing serious injury or
death. Do not tie down the throttle valve so it will not shut off when released. If the throttle valve
does not stop the unit immediately when released, repair or replace it. Slowly squeeze the air throttle
valve lever to start the driver. Opening the throttle valve slowly will prevent a violent start of the dri-
ver. Never use anything to keep the throttle valve lever in the open position other than the operator’s
hand. For safety, the valve must close, stopping the drive, when the operator releases the valve lever.
WARNING CHUCK SIZING: A chuck or chuck adapter that is too large for the post being driven may contribute
to a condition which would allow the post driver to fall from the post causing serious injury or death.
Do not use a chuck or chuck adapter that is too large for the post being driven. The post should be
loose in the chuck or chuck adapter with a minimum of 1/8" (3 mm) clearance and not over 5/8"
(15.9 mm) clearance. The post driver piston should hit the post as squarely as possible. If the fit is
too loose, damage may be caused to the driver, its chuck or chuck adapter causing your driver, its
chuck or chuck adapter to fail. Chucks and chuck adapters wear out and should be replaced as
needed. Inspect your driver’s chuck and chuck adapters frequently. If you are in doubt, return your
chuck, chuck adapter, or any other part to the factory, freight prepaid, for a free inspection.
WARNING SAFETY EQUIPMENT: Do not operate the post driver unless the operator and any others near the
post driver are wearing hard hats, safety glasses, safety shoes, ear protection, back supports, anti-
vibration gloves, and 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.
WARNING SAFETY CHECKS: Check your driver daily for loose bolts, cracks, bulges or abnormalities in welds,
castings, chuck or chuck adapters, top cover plate, piston, air line, or any other part. Do not repair
any parts. Immediately replace worn or defective parts with new parts. Do not run the unit with worn
or defective parts. If you are in doubt, return your driver, chuck, chuck adapter, or any other part to
the factory, freight prepaid, for a free inspection.
Model PD-39 Air Operated Post Driver
OPERATING & SERVICE INSTRUCTIONS

WARNING REMEMBER ALWAYS PUT SAFETY FIRST! Do not operate the post driver if any unsafe conditions
are present.
CAUTION Do not put anything but a post into the chuck on your driver.
CAUTION Do not operate your post driver unless it is on a post to be driven. Operation of the driver without it
driving on a post could damage it.
WARNING If your post driver’s warning label is marred or destroyed, replace it immediately. Simply call Rhino
LABELS: Tool Company and we will send you a new warning label at no charge.
LUBRICATION: YOU MUST OIL YOUR POST DRIVER WHILE IT IT IS OPERATING. Set the lubricator on your Filter-
Regulator-Lubricator in the air line to the post driver so it will deliver approximately 10 drops of oil
per minute. Preferably the Filter-Regulator-Lubricator should not be separated from the driver by
more than 25 ft. of hose. Make certain that any new air hose between the Filter-Regulator-Lubricator
and the post driver has been thoroughly lubricated. The procedure for lubricating the hose is as fol-
lows - Remove the air hose from your post driver and (CAUTION!) AFTER SECURING THE AIR LINE
S0 IT CAN’T WHIP AROUND TO INJURE SOMEONE, open the lubricator wide open so that a steady
stream of oil runs into the air stream after the throttle valve has been activated.
Actuate the air throttle valve and run the air through your hose until an oil film is felt coming out of
the air hose where it connects to the driver. Periodically check to make sure your driver is receiving
oil. Air and oil will be exhausted through the chuck. If in doubt, remove the air line from the driver
and using the same procedures stated above check to see if an oil film is being exhausted from the
hose end that connects to the driver. If oil is coming out of the hose, reconnect the air hose to the
driver.
Use SAE 5 wt. oil in cold weather (in very cold conditions you may want to dilute your SAE 5 wt. oil
to provide proper lubrication), SAE 10 wt. oil for mild weather to 80 degrees and SAE 20 wt. oil for
hot weather.
AIR SUPPLY: You must have an adequate supply of clean air at the proper pressure. Air supplied to your post dri-
ver must be filtered. Drain water from the air compressor air tank prior to use. Use a Filter-
Regulator-Lubricator to help remove water, rust and other particulate from the air supply. It will
greatly increase the life of your post driver and decrease maintenance costs.
PD-39 AIR REQUIREMENTS: 42 CFM (1.19 m3/min.) @ 90 PSI (6.4 kg/cm2)
AIR HOSE: It is recommended that you use a 3/4" double braid air hose with an oil resistant lining to supply air
to your post driver.
GENERAL INSTRUCTIONS _________________________________________________________________________
1. Blow out air lines before coupling them to your post driver. This precaution will help remove any dirt that may
have entered an open hose. CAUTION: Do not turn on pressurized air through an unsecured air line; the air line
could whip around causing serious injury.
2. Check your Filter-Regulator-Lubricator. Make sure the regulator is set at no more than 90 PSI (6.4 kg/cm2). See
(WARNING: AIR PRESSURE), for instructions. Make sure the filter has been drained and the lubricator filled with
the proper weight oil. See (LUBRICATION), for instructions.
3. Do not use a chuck or chuck adapter that is too large for the post being driven. See (WARNING:
CHUCK SIZING), for instructions. If the fit is too loose it is not safe to operate the driver, damage
may occur to the driver and the driver may batter the end of the post.
4. Place the driver over the post to be driven and grasp the handles firmly. Slowly squeeze the air
throttle valve lever to start the driver. Opening the throttle valve slowly will prevent a violent start of
the driver. As the driver starts, pull down on the spring loaded handles. Because the driver is light-
weight, a downward pressure of 10 to 15 lbs per handle is required to reach driving efficiency. Never
-2-

tape, wire, etc., the throttle valve lever open or try to operate without a firm grip on both handles. Your throttle
valve can be used to control the speed of driving. The more air your driver receives the faster it will hit the post up
to maximum speed. See (AIR SUPPLY). PD-39 AIR REQUIREMENTS: 42 CFM (1.19 m3/min.) @ 90 PSI (6.4
kg/cm2)
5. Keep dirt out of the chuck. It could enter the unit causing damage. If dirt gets into the chuck, disconnect the driver
from the air supply, remove the chuck and clean the dirt out. Be careful to keep dirt out of the driver during re-
assembly and be sure the bolts holding the chuck are tight and properly torqued. See the bolt torque chart and
drawing below for proper bolt torque and lock washer assembly.
Make certain the surfaces are free of dirt, oil and grease. It is important to install compression washers properly or
they will not lock the bolt or nut securely. Place the compression washer with the center of the cone next to the bolt
head or nut being tightened (See DRAWING). Then tighten the bolt or nut with a torque wrench until the proper torque
for the size of bolt being tightened is reached (See BOLT TORQUE CHART). Check bolt and nut tightness daily.
If you are driving the same temporary posts time after time, the posts will tend to fill with dirt after a few drives.
The dirt may be pumped out the top of the post into your driver. Rhino Tool Company suggests you pinch the lower
end of the post together, which will keep the dirt out.
There are several benefits to doing this. It will decrease the weight of your temporary post stock by hundreds of
pounds making it easier to handle the posts, it eliminates the mess of dried dirt falling out of the posts and eliminates
hundreds of pounds of extra weight being hauled time and again by your trucks and trailers which saves you fuel.
SERVICE INSTRUCTIONS _________________________________________________________________________
1. Check air pressure setting regularly.
2. Check oil supply regularly; fill when needed.
3. Drain and clean air filter regularly, especially in winter.
4. Check to see that the water is drained from the air compressor reservoir regularly.
5. Check the bolts on your post driver daily to make sure they are tight. Do not over torque the bolts (See BOLT
TORQUE CHART). If you disassemble the driver, during reassembly, after tightening the bolts on the top cover of
the PD-39 with the proper torque, make sure the unit isn’t connected to the air supply, then with the throttle valve
open to allow air movement in and out of the driver, cycle the driver’s piston up and down by hand to make sure it
is not binding. This can be done through the bottom of the chuck. If the piston binds at any place during the cycle,
loosen the top cover and re-torque with an alternating sequence like you would the head on an automobile engine.
Do not run the driver if the piston binds. Feel free to call the factory with any questions.
6. Both of your Model PD-39 spring-loaded handles should be lubricated periodically. To lubricate the handles, refer
to the parts drawing for the Model PD-39 and follow the procedure outlined below.
A. Loosen and remove hose fitting Part No. 606605.
B. Remove the 4 cap screws Part No. 500000 from both handles.
C. Gently tap the handle keeper Part No. 70180 downward to remove it from the bottom handle tubes.
D. Carefully remove both handles. (Do not attempt to remove springs Part No. 610011 from the handles.)
E. Clean all parts with solvent and dry.

8. When you store your post driver between jobs put extra oil in the air line and blow it into the unit. Slowly roll the
driver over to allow the oil to coat all inside surfaces, then stand the driver upright, to allow any condensation
to drain. If you store the driver for a prolonged period, it should be oiled every month or so depending on the
humidity.
9. Immediately replace any damaged or worn parts with new ones. If you think your driver, or any other Rhino prod-
uct or part is not performing properly, let Rhino or your Rhino dealer, distributor, or representative know. If you
don’t know what is wrong with your Rhino unit, you can send it, freight prepaid, to Rhino and we will examine it
free and let you know what is wrong, if it can be fixed and how much, if anything it will cost to repair it. This is a
Rhino service at no charge to you. Remember, freight must be prepaid and please call first so we are looking for
your unit. If there is nothing wrong with your unit or if your unit is repaired Rhino always replaces all bolts, lock
washers, and gaskets and there is a charge for those parts along with reassembly. Replace damaged warning
labels immediately. Call Rhino and we will send you a new label, no charge.
You have purchased a quality, rugged post driver and if you give your Rhino Model PD-39 Air Operated Post Driver
reasonable care, it will give you efficient, trouble-free post driving.
