HYDRAULIC MAINTENANCE
There are only FIVE 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 - 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. Hydraulic tank capacity is approximately 17 US gallons.
The machine is shipped from the factory with Texaco Rando HD 46 hydraulic oil. Generally any brand of recognized
mineral 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 to
1/3 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
ESSO NUTO H46
Mobil Mobil DTE 25
Shell Tellus 46
Petro Canada Harmony AW 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 1500 PSI (10339 kPa) for H-40 and should not require further attention
except precautionary observation at start-up and every few days thereafter.
CLEANLINESS
The H-40 series design should endure heavy operating conditions and provide the customer with flawless machine
performance. To extend good performance some care is required, especially cleanliness. The following areas should be
kept clean of dirt, grease and chips:

CONTROL CONSOLE

DOOR CHARTS

WHEEL BOXES

BLADE GUIDES
NOTE: All parts should be cleaned before any repair or service is performed on them.
