HYDRAULIC MAINTENANCE
There are four items of routine maintenance associated with the hydraulic system of the V-25APC. With proper mainte-
nance the hydraulic system of the V-25APC should provide years of reliable service.
1.
OIL FILTER
- Ten micron filtration of the hydraulic oil is provided by a spin on type filter mounted on the tank
return line as shown below. The element should be changed every 500 working hours or a minimum of at least once per
year. Suitable replacement elements are:
CANFLO - RSE-30-10
GRESEN - K-23018
LHA - SPE-15-10
ZINGA - AE-10
2.
OIL LEVEL
- The oil level should be maintained in the upper half of the level gauge. Normally the rate of oil con-
sumption will be very low and it should be unnecessary to add oil more often than at filter changes. Add oil only to the top
line on level gauge. The hydraulic tank capacity is 8 US gallons.
NOTE:
The V-25APC is shipped from the factory with Texaco Rando HD 46 oil. Generally any brand of recognized min-
eral hydraulic oil with the same properties should be compatible with Texaco Rando HD 46 oil, but to avoid any risk we
suggest staying with Texaco Rando HD 46. If it is desirable to change brands, it is necessary to drain the tank and to fill
to1/3 with the new oil. Operate through several full strokes of each cylinder, drain the tank again, and finally fill the tank
with the new brand.
Recommended replacement oils:
Chevron - AW Hydraulic Oil 46
Conoco - Super Hydraulic 46
Mobil - Mobil DTE 25
Esso - NUTO H46
Shell - Tellus 46

HYDRAULIC OIL CHANGE -
Oil visual inspection should be conducted with every filter change for the following
signs of degradation: Milky or hazy oil colour
Burnt smell
Varnish or sludge formation
Increased viscosity
If one of the above is observed, oil should be changed. It is recommended to change the oil after 6000 hours of operation
or every 2 years.
4.
OIL TEMPERATURE
- Oil temperature is indicated by a thermometer contained in the level gauge. Oil tempera-
ture during steady operation should stabilize at about 50 - 55°F (10
˚
- 13°C) above room temperature. Thus in a 70°F
(21C) shop one might expect an oil temperature of about 120°F (49°C). Oil temperature should never exceed 160 F°
(71°C).
5.
OIL PRESSURE
- Oil pressure is factory set to 1000 psi and should not require further attention
Filter
Hydraulic tank and manifold assembly
are mounted on a door located on the
infeed side of the base. The level and
temperature gauge is found on the
front of the door.
