MAINTENANCE
Hydraulic System.
High pressure Filter.
For additional protection to the Proportional Valves,
that control the Robotic Arm, a High Pressure Filter
‘
A ’, is installed between the Hydraulic Tank and the
Proportional Valves. It is mounted on the left side of
the tractor, aft of the left front wheel.
The Filter Cartridge should be change after the
initial
25 hours of operation , and then every 100 hours , or
at any time the Gauge ‘ B ’ on the Filter indicates that
the filter efficiency is reduced. When the Filter
Cartridge reaches this point, a switch in the filter head
‘closes’, and the ‘
RED ’ Indicator Flag is activated. Also
a signal is sent to the Control Panel Display to warn
the operator that ‘filter service’ is necessary.
Main In–Tank Filter.
It is recommended that the In-Tank Filter Element is
changed
every 750 hours.
•
Before loosening the bolts in the Top Plate ’ C ’,
open the Filler Cap ‘ D ’ to relieve tank
pressure.
•
Press ‘DOWN’ on the Top Plate, against
spring pressure, at the same time turn it
‘counter clockwise’ to remove it.
•
Check the Top Plate O-Ring ‘ E ’. Replace it if it
is damaged.
•
Clean the Magnet ‘ F ’ of any metallic residue.
•
Remove the used Cartridge ‘ G ’ from the tank.
Install a new Cartridge. Check that the O-Ring
is correctly seated in the Top Plate and all
surfaces are clean.
•
Refit the Top Plate by pressing ‘DOWN’ and
turning ‘clockwise’ to locate it against the bolts
and tighten the bolts.
IMPORTANT
When the Filter or Filler Cap are removed during
service, cover the tank openings to prevent any dirt,
debris or other contaminants from entering the tank.
It is recommended that the Hydraulic Oil is changed
very 750 hours or annually, when the Main Filter is
changed.
•
Always drain the oil into an approved
container.
•
Clean and replace the ‘magnetic’ drain plug.
•
Refill the tank using only an approved
hydraulic oil as shown on page 35.
•
Fill to the correct level indicated on the Sight
Glass ‘
H ’, on the oil tank. DO NOT overfill.
IMPORTANT
To ensure maximum cooling, do not stack sod on the
front tractor weights. If more front weight is needed
add more weights, or ballast the front wheels.
