♦
Oil supply:
If the oil supply of the power source
exceeds the flow prescribed, the engine's rpm
must be reduced, until correct oil flow is achieved.
Test equipment can be used, see Spare parts list.
♦
Oil flow divider:
If the oil flow cannot be
adjusted by lowering the rpm, an oil flow divider
must be installed. This will secure the post driver
the correct oil flow and lead excess oil back to the
tank (or to the operating valve block).
♦
Pressure relief valve:
To protect the post driver
against too high a pressure, the pressure relief
valve of the powerpack must be set in accordance
with the technical data. If that is not possible,
connection can be made by installing a separate
pressure relief valve. In case of doubt, contact
your nearest authorised workshop.
Starting the post driver
NOTICE
In cold conditions, warm up the post
driver by using it moderately for a few minutes
before start working.
1. Always use a suitable adaptor for the post and
for the post driver. Place the adaptor in the front
head of the post driver. See section "Adaptors".
2. Remove the protective caps from the
quick-release couplings.
3. Clean the quick-release couplings if needed and
connect the tail-hoses to the extension hoses of
the power source.
4. Insert the post into the post driver. It is possible
to use an optional drive cap.
5. Lift the post and post driver to a vertical position.
For long and heavy posts, two persons may be
required.
6. Activate the trigger by pressing the handles
down. When the post driver is within reach,
grasp the handles.
7. Avoid activating the post driver when it is
removed from the post. This will otherwise lead
to increased hydraulic oil temperatures and seal
wear.
8. Do not invert the post driver without first
isolating the hydraulic supply.
9. Do not continue to work if the hoses vibrate
abnormally.
10. Investigate the contents of the material in which
you are going to work. Look out for hidden
cables and pipes, for example electricity,
telephone, water, gas, or sewage lines.
11. Only use the machine for the jobs for which it is
intended.
Stopping the post driver
1. Stop pressing the handles and lift the handle
trigger.
2. Switch off the power supply.
3. Disconnect the hoses and fit the protective caps
on the quick-release couplings.
Disconnecting the post driver
1. Isolate the hydraulic supply.
2. Disconnect the hoses by pulling up the locking
rings and pulling up the couplings. Fit blanking
caps to the hoses.
When taking a break
♦
During all breaks you must place the machine in
such a way that there is no risk for it to be
unintentionally started. Make sure to place the
machine on the ground, so that it can not fall.
♦
In the event of a longer break or when leaving the
workplace: Switch off the power supply and then
bleed the machine by activating the start and stop
device.
Maintenance
Regular maintenance is a basic requirement for the
continued safe and efficient use of the machine.
Follow the maintenance instructions carefully.
