Hydraulic fluid may be hot if system has been in operation. Allow time for system
to cool before performing maintenance or serious injury to personnel may result.
Hydraulic fluid may be under pressure. Use caution when disconnecting hydraulic
lines or components. Face shields or goggles must be worn or serious injury to
personnel may result.
Hydraulic fluid may be absorbed through the skin. Avoid prolonged exposure to
skin and wear long sleeves, gloves, and goggles or face shield. If hydraulic fluid

If hydraulic fluid gets on skin, wash thoroughly with soap and water. Wash hands
thoroughly prior to eating or smoking.
A steering hydraulic cylinder weighs (empty) 110 pounds (50 kg). Two people

and steering plate #5 or serious injury to personnel may result.
The following procedure is to be used for either streetside or curbside platform
steering cylinder. Repeat this procedure as necessary for other cylinder repairs.
Using two 36-inch (91 cm) clear hoses and a drain pan, bleed steering cylinder (1) at bleed valves (2) to relieve
