Oil Supply
•
Daily before starting up check oil level in tank reservoir.
•
It is a good practice to constantly keep an eye on the tank level gauge,
(this can be seen from the tractor seat) as a pipe burst could empty the
tank within minutes.
•
A pump or motor starved of oil will be damaged beyond repair.
•
Replace oil if signs of contamination occur (discoloured)
•
Contamination can be reduced by:
•
Thoroughly cleaning around reservoir cap before removing.
•
Using a clean container when replenishing the system.
•
Regularly servicing the filtration system.
•
Never allowing oil level to fall below the sight gauge.
•
Daily inspect all hydraulic connections and fittings to be in good order.
Any damage or leaks must be rectified immediately, this is part of the
daily maintenance and is your responsibility, to maintain a long reliable
working life.
•
When tightening fittings always use two spanners when necessary and
do not over tighten. If a fitting leaks it will need to be replaced.
Filtration Maintenance
The machine is protected by a suction strainer and a low-pressure full flow
return line filter.
1. The suction filter is permanently fixed in the reservoir tank. Should
symptoms of pump cavitations or spongy operation occurs, the tank
must be drained, the tank and suction filter thoroughly cleaned and
dried before refilling with clean oil.
2. The return line element should be replaced after the first 50 hours and
thereafter at 300-hour intervals. It is most important to replace the filter
within these intervals because once blocked, oil will bypass the filter
element infiltrated.
3. When tightening fittings always use two spanners when necessary and
do not over tighten. If a fitting leaks it will need to be replaced.
