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.
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 every 500 working hours or once per year. Suitable
replacement elements are:
CANFLO RSE-30-10
GRESEN K-23018
LHA SPE-15-10
ZINGA AE-10
2. OIL LEVEL - 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 level gauge.
The H-40 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, but
to avoid any risk we suggest staying with Texaco Rando HD 46. If it is desired to change brands, it is
necessary to drain the tank and 1/3 refill it 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.
Hydraulic tank capacity is approximately 17 US gallons.
Recommended replacement oils:
Chevron AW Hydraulic Oil 46
Esso - NUTO H46
Mobil - Mobil DTE 25
Petro Canada - Harmony AW 46
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° above room temperature. Thus in a 70 F°
shop one might expect an oil temperature of about 120 F°. Oil temperature should never exceed
160 F°.
4. OIL PRESSURE - Oil pressure is factory set to 1200 psi on the H-40 and should not require further
