Hydraulic Fluid
Fill the hydraulic reservoir with the recommended fluid (Normally Automatic Trans-
mission Fluid. ATF - Type F ) to the indicated mark.
Hydraulic Fluid
Fill the hydraulic reservoir with the recommended fluid (Normally Automatic Trans-
mission Fluid. ATF - Type F ) to the indicated mark.
Alternate fluids are listed in the 'Recommended Hydraulic Fluids' section.
If long lengths of new hydraulic hoses that are not filled with fluid are connect-
ed, then additional fluid will have to be added after the lines have been filled.
An additional 2.3 gallons (8.7 Lt.) of fluid is required for every 100’ (50’ [12.7
m] hose set) of 3/4” (19 mm) diameter hose connected to the power supply.
Drain and refill after every 2000 hours.
If the oil becomes contaminated drain and refill more frequently.
A visual observation through the sight glass level indicator is required.
Hydraulic Hoses
Visually inspect the Hydraulic Hoses and replace if damaged.
For detailed testing, a test rig consisting of:
Male quick disconnect, 22 gpm (10 L/s) minimum capacity flow meter, 2000
psi (13790 kPa) pressure gauge, shut-off valve (rated at 2000 psi [13790
kPa]) and a female quick disconnect
May be coupled between the hoses.
Open the shut-off valve to full volume flow at low pressure which will be
obtained with ‘fill’ actuation of the control knob.
By closing down the shut-off valve of the test rig, reduced flow at a higher
pressure is obtained and full bypass pressure is obtained and indicated at
zero flow.
