The Hydraulic Oil Reservoir is mounted directly behind the cab.
This fully baffled tank contains approximately 200 litres (45 gallons) of oil, (see lubrication section).
It is this oil, which is the lifeblood of the machine, and, because of this, it must be kept exceptionally clean.
A 'Suction Filter’ fitted on the right hand side of the tank top, filters the oil before it enters the 'boost pump'. All
return oil, except wheel motor drainage, passes through a 'Return Filter’ fitted on the left hand side of the tank
top. Wheel motor drain oil passes through a separate magnetic filter located in front of the Compressed Air
Tank.
A level gauge is fitted to the left side of the tank, and contains a thermometer.
The oil level must always be between the min/max lines on this level gauge. The oil reservoir temperature
should stabilise between 50°C - 80°C.
When topping up the reservoir, use a clean container and the correct grade of oil -
NOT UNIVERSAL
TRACTOR OIL.
If the vehicle Horn sounds and the Electronic Dash Display shows a normal Oil Temperature (below 80°C),
STOP IMMEDIATELY and check the Oil Level. A float switch is fitted to the side of the tank which, when the Oil
Level drops dangerously low, the vehicle horn will sound. Investigate the cause and fix before continuing.
Test Horn Daily.
All filters must be changed after the
first 10 hours
and, thereafter, every 250 hours or when the clogging
indicator shows a blockage, whichever comes first.
SAM LTD ONLY RECOMMENDS THE USE OF SAM SUCTION AND RETURN FILTERS.
When changing oil filters, always change the O Ring with the correct one supplied.
A sample of hydraulic oil should be analysed at the beginning of each season to ascertain as to whether the oil
should be changed or not. Your oil supplier can usually carry this out.
Water is the usual cause of contamination in hydraulic oil and can normally be traced back to condensation in
the oil tank.
If emulsified oil is present, it is instantly recognisable as a milky yellow translucent liquid in the sight gauge.
The oil must be changed IMMEDIATELY.
Every time the tank is emptied, the opportunity should be taken to clean the strainers within the tank.
Only 'lint free' cleaning material should be used inside the hydraulic tank.

The vehicle Horn will also sound if the Transmission Oil Temperature becomes excessive, which will also be
indicated on the Electronic Dash Display (the pointer will be above 80°C and the warning symbol will be
illuminated red.
Should the Horn ever sound for this reason, DO NOT STOP, as this will trap the excessively hot oil within the
'closed loop' circuit, simply reduce speed by approximately 25% by pulling back the joystick. The Horn will
stop sounding after approximately 5 minutes.
