SAFETY INSTRUCTIONS
(continued)
HYDRAULIC CONTROL VALVE &
MOUNTING BRACKET PARTS DRAWING
Please remember it is important that you read and heed the safety signs on the post driver, and the safety rules
set forth. Clean or replace all safety signs if they cannot be clearly read and understood. They are there for
your safety as well as the safety of others. The safe use of this machine is strictly up to you, the operator.
All things with moving parts are potentially hazardous. There is no substitute for a cautious, safe-minded
operator who recognizes potential hazards and follows reasonable safety practices. The manufacturer has
designed this driver to be used with all its safety equipment properly attached, to minimize the chance of
accidents. Study this manual to make sure you have all safety equipment attached.
Make sure that all operating and service personnel know that in the event hydraulic fluid penetrates the skin,
it must be surgically removed within a few hours by a doctor familiar with this form of injury, or gangrene may
result.
If a safety shield or guard is removed for any reason, it must be replaced before the machine is again operated.
Before servicing the machine, engage the parking brake or place the transmission in “Park”, shut off the trac-
tor and remove the key. Relieve all hydraulic pressure in lines.
When the use of hand tools is required to perform any part of assembly, installation, adjustment, maintaining,
repairing, removal, or moving the driver, be sure the tools used are designed and recommended by the tool
manufacturer for that specific task.
Personal protection equipment including hard hat, safety glasses, safety shoes, and gloves are recommended
during assembly, installation, operation, adjustment, maintaining, repairing, removal, or moving the driver. Do
not allow long hair, loose fitting clothing or jewelry to be around moving parts.
Always use two people to handle heavy, unwieldy components during assembly, installation, removal, or
moving the driver.
Never place any part of your body where it would be in danger if movement should occur during assembly,
installation, operation, maintaining, repairing, removal, or moving the driver.
Never place yourself between the tractor and post driver while implement is in operation.
Do not walk or work under a raised driver ram unless it is securely blocked or held in position. Do not depend
on the tractor hydraulic system to hold the driver ram in place.
Never leave post driver ram in the raised position. Always lower ram to the ground or to the transport position
and install the transport lock pin before transporting or storing.
A heavy load can cause instability of the tractor. Use extreme care during travel. Slow down on turns and
watch out for bumps. The tractor may need front counter-weights to counter-balance the weight of the driver.
Do not allow riders on the driver or tractor at any time. There is no safe place for any riders.
NOTE: Post Drivers prior to S/N 2656 (HPD-16)
and S/N 2987 (HPD-20) used valve #814473 (Gresen).
