6. Activate the trigger. When the LPD is within reach,
grasp the handles.
7 When driving, make sure you are able to keep safely
balanced. Keep arms and legs clear of the post, if a
post breaks during operation the post driver with a
projecting broken shank will suddenly drop.
8 Avoid activating the post driver when it is
removed from the post and ground. This will lead to
increased hydraulic oil temperatures and seal wear.
9 DO NOT invert the post driver without first isolating
the hydraulic supply.
11 Do not continue to work if the hoses vibrate
abnormally.

12 Do not "ride" the machine, e.g. with one leg slung
over the handle. This could result in injury, especially if
the tool were to break.

are going to work. Look out for hidden cables and
pipes, e.g. electricity, telephone, water, gas, or sewage
lines.
14 If you suspect that the post has struc k a hidden
object, stop the machine immediately. Make sure there
is no danger before continuing with the work.
15 Only use the machine for the jobs for which it is
intended.
Be alert
Always concentrate on what you are doing. Use
common sense. Never operate the machine when you
are tired or under the influence of drugs, alcohol or
other substances which might affect your vision,
