instructions provided are unclear or not
understood. Proper care is your responsibility.
Always follow all State and Federal health and
safety laws and/or local regulations.
To help prevent personal
injury, protective
equipment must be worn
during Post Driver
assembly, operation, and
maintenance. Personal
protective equipment
should include, but not
be limited to, safety glasses, hearing
protection, protective gloves, and steel toe
footwear.
Personal injury can result
from slips or falls. DO
NOT leave tools or parts
laying around the work
area, and clean up all spilled fluids
immediately.
Hazard Avoidance
Inspect this equipment before each
use. Make sure all hardware is
tight. Always replace worn or
damaged parts before use.
To avoid personal injury or death,
do not operate the Post Driver by
yourself. Always have another
person to control the machine or
power source.
Make sure all decals are securely
attached to the Post Driver and are
legible at all times. Always read
and understand all decals before
working on or operating the Post Driver.
Make sure all lock-pins
and transport supports
are secured in place
before transporting or
storing the Post Driver..While transporting,
never ride on or permit others to ride on the
Post Driver..
Improper operating
procedures can create risk
for the operator and
bystanders. DO NOT use the
Post Driver before making sure no one will be
endangered.
To prevent personal
injury or death, be aware
of overhead electrical
lines when operating the
Post Driver. Electrocution can occur even
without direct contact with overhead power
lines. Proceed cautiously around electrical
lines and utility poles.
To prevent personal injury
or death, always check for

Potential pinch points.
Keep hands clear of Post
Driver while operating.
Never place hand(s) on
top of a post when inserting it into
the Post Driver. Always close the safety arm
before driving the post.
To avoid personal injury
do not attempt to clean,
adjust, or lubricate the
Post Driver while it is in
motion.
The rubber debris guard helps
shield the operator from flying
debris that may be generated
during post driving. To avoid
personal injury, make sure the rubber debris
guard is securely attached to the Post Driver
before driving posts.
To avoid personal injury or death,
do not modify the Post Driver by
welding, drilling, or grinding. Do
not expose to extreme heat, such
as from a torch.
The main carriage channel
assembly is tall and heavy. To
avoid tip over, resulting in serious
injury or death, leave the overhead
lifting device attached to the main carriage
channel while assembling components.
To avoid serious injury or death, the
safety arm must be installed after the
Post Driver has been mounted on a
machine, or the freestanding Post
Driver has been secured to prevent tipping.
Hydraulic Hoses
Avoid damaging hydraulic hoses.
Avoid sharp bends and kinks when
routing hydraulic hoses. Using a
bent or kinked hose will cause
severe back-pressure. Sharp bends and
kinks can internally damage the hose,
leading to premature hose failure, resulting
in personal injury.
Do not drop heavy objects on
hoses. A sharp impact may cause
internal damage to the hose.
Applying pressure to a damaged
hose may cause it to rupture, resulting in
personal injury.
Mismatched couplings
and hoses can cause the
coupling to violently
disconnect from the hose
when placed under pressure; separating
with sudden, extreme force which can result
in property damage, personal injury, or
death.
Replace a hose if any of the following
conditions are present:
- End fittings that are damaged or leaking
- Outer coverings that are chafed or cut
- Wire shields that are exposed
- Outer coverings that are ballooning
- Flexible part of the hoses that are kinked
- End fittings that are displaced
Pressure can be trapped
in a hydraulic system.
Trapped pressure can
cause sudden movement
of an attachment. Use caution when
disconnecting hydraulic lines or fittings.
High-pressure oil that is released can cause
a hose to move violently while spraying oil.
Escaping high-pressure fluid can
penetrate the skin, causing serious
injury. Relieve pressure before
unhooking hoses. Check/tighten
all connections before activating hydraulics.
Never use your hand to check for leaks.

Safety Stop Adjustment
To avoid serious injury, inspect the
control valve safety stop before
using the Post Driver the first time
and/or before each daily use.
Adjust the safety stop as needed, per the
following procedure. Make sure all control
valve hardware is tight. Always replace worn
or damaged parts before use.
The control valve safety stop prevents
unintentional activation of the Post Driver
control valve and must be functional at all
times.
If the Post Driver is operational, make sure the
machine/power source is OFF, parking brake
is set, road lock pin is installed, and all
hydraulic pressure is released (zero pressure).
1. Attempt to push main hydraulic control
valve lever (G5) forward (away from
operator) without squeezing (pulling) yellow
tipped control valve safety lever (G7).
