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 which is 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. Any damage or leaks must be
rectified immediately, this is part of the daily maintenance and it is your responsibility
to help maintain a long reliable working life.

When tightening fittings always use two spanners when necessary and do not over
tighten. If a fitting persists in leaking it will need to be replaced.

Recommendations
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 cavitation or spongy operation occur the tank must be drained, and the tank
and suction filter thoroughly cleaned and dried before refilling with clean oil.
2.
The return line filter element should be replaced after the first 50 hours and thereafter
at 300-hour intervals
… or yearly. It is most important to replace the filter within these
intervals because once blocked, oil will bypass the filter element infiltrated, causing
pump & motor damage
3.
If any failure or replacement of hydraulic parts have occurred then the return line filter
must be replaced immediately
