Filling Reservoir
Pump hydraulic oil through an adequate filter into reservoir. Fill until
oil level indicator is
2 / 3 - 3 / 4 full. Inspect for leaks. Reservoir capacity is
70 liters (18.5 gal.). Approximately 55 liters (14.5 gal) will be needed for
the reservoir. If installation is completed with empty hoses, extra oil will
be needed to meet the
2 / 3 - 3 / 4 tank fill indicator requirement.
Hydraulic Oil
Harken recommends mineral-based, ISO 46 grade oil. Refer to Oil
Equivalent Table below. If HPU is primarily used in an extreme cold
weather environment, ISO 32 is suitable.
Characteristics of good quality, mineral-based hydraulic oil are:
• Good anti-wear performance
• Resistance to oxidation depredation
• Protection against rust and corrosion
• Resistance to foaming
• Ability to separate water rapidly
• Suitable for widely varying temperature conditions
• Good low temperature flow properties
• Retains viscosity/temperature characteristics while in service
• Universally available
Note: If the hydraulic installation was completed with empty hoses,
be sure to have extra oil on hand to top off the tank as the
hoses are filled.
Oil Level
Indicator
CAUTION! Never run the HPU pump without oil. This will void warranty.
When commissioning hydraulic equipment, it is extremely important to carefully follow each procedure to avoid premature system damage
and/or failure. Secure connections, ensure cleanliness, confirm proper fluid levels and perform all recommended tests. The following are
instructions to ensure proper commissioning of your Hydro 2.
