General Safety Instructions
Hydraulic fluid may be hot if system has been in operation. Allow system to cool
before performing maintenance or injury to personnel may result.
Hydraulic fluid may be under pressure. Use caution when disconnecting hydraulic
components or injury to personnel may result.
Hydraulic fluid may be absorbed through the skin. Wear long sleeves, gloves, and
goggles or face shield. If hydraulic fluid gets into the eyes, flush them immediately
with water and seek medical attention. If hydraulic fluid gets on skin, thoroughly
wash with soap and water. Wash hands thoroughly prior to eating or smoking.
Throughout this procedure, all fittings and openings must be capped or plugged
immediately after opening to prevent dirt and moisture or foreign material from
entering the hydraulic system or damage to equipment may result.
The hydraulic tank has a capacity of 16.5 gl (62.5 l). With the platform at road
height and gooseneck at coupling height, the hydraulic tank should contain
approximately 8 gl (30 l) of hydraulic fluid.
