Guidelines
When you measure the voltage at solenoids,
make sure the hydraulic lines and components
are fully installed.
Use an ohmmeter to measure wiring continuity
to solenoids. Use an ammeter to measure for
the correct current to the solenoids and
contactor coils.
Unless otherwise directed, disconnect
the battery connector when you
examine electrical circuits or
components with an ohmmeter.
Electrical current can damage to the
ohmmeter.
Visually inspect all hydraulic lines and
components for:
• Leaking connections or connectors
• Loose or broken fittings
• Damaged tubing, hoses, vents, or seals
Inspect the hydraulic system for the correct
pressure and that the relief valve is functioning
correctly. See “Hydraulic Pump Pressure Relief
Valve Adjustment” on page 7-103.
Check the hydraulic reservoir fluid level. If
necessary, add fluid; fill until fluid is visible to
within 1 in. (25.4 mm) below the fill port elbow.
The usable reservoir capacity is 0.9 qt. (0.85 L).
See “Lubrication Equivalency Chart” on
page A-2.
N
OTE: Always check hydraulic fluid level with
forks fully lowered and when hydraulic
fluid is cold.
Cap any open hydraulic lines to prevent
contamination.
