HYDRAULIC MAINTENANCE
There are only FOUR items of routine maintenance associated with the hydraulic system.
1. OIL FILTER - Ten micron filtration of the hydraulic oil is provided by a spin on type filter mounted on the
tank return line . The element should be changed after the first 50 Hours of operation and then every 500 working
hours. Suitable replacement elements are:
CANFLO RSE-30-10
GRESEN K-22001
PARKER 921999
ZINGA AE-10
2. OIL LEVEL & REPLACEMENT- The oil level should be maintained in the upper half of the level gauge.
Normally the rate of oil consumption 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 the gauge. In general, if the oil level is maintained and the filter is
changed as recommended, there is no need to change the oil unless there are visible signs of degradation such as;
Rapid darkening of oil.
Milky or hazy oil colour.
Varnish or sludge formation.
Burnt smell from the oil.
However, if the machine is exposed to extreme temperature variation and high humidity, then the oil should be
changed every 2000 operating hours or at least once a year. To change the oil, it is necessary to drain the tank (a
drain plug is found on the bottom of the tank) and fill it to 1/3 full level with the new oil, operate through several fully
automatic cycles with the index set to full stroke and the head to full rise. Drain the tank again, and finally fill the
tank with the new oil. Hydraulic tank capacity is approximately 8 US gallons.
Recommended replacement oils: Chevron AW Hydraulic Oil 46
Esso NUTO H46
Mobil Mobil DTE 25
Texaco Rando HD 46
Shell Tellus 46
3. OIL TEMPERATURE - Oil temperature is indicated by a thermometer contained in the level gauge. Oil
temperature during steady operation should stabilize at about 50 - 55 F° ( 10-12°C ) above room temperature. Thus
in a 70 F° (20°C) shop one might expect an oil temperature of about 120 F° (50°C) Oil temperature should never
exceed 160 F° (70°C)
4. OIL PRESSURE - Oil pressure is factory set to 500 PSI (3263 kPa) and should not require further
attention except precautionary observation at start-up and every few days thereafter.
CLEANLINESS
The heavy duty design should endure heavy operating conditions and provide the customer with flawless
machine performance. To extend good performance some care is required especially as cleanliness is concerned.
The following areas should be kept clean:
- Control console free of dirt and grease.
- Door charts free of dirt and grease.
- Wheel boxes free of chips.
- Blade guides free of chips.
- Outfeed table free of chips.
- A large chip build-up should be avoided in the base of the saw.
NOTE: All parts must be cleaned before any repair service can be performed on them.
