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.
The safety arm is spring loaded. 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. 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.
