Hydraulic Hose Installation Instructions
WARNING
JKeep hands and body away from pres- surized lines. Use paper or cardboard, not body parts to check for leaks. Wear safety goggles. Hydraulic fluid (oil) under pres- sure will easily penetrate skin and can cause serious injury or death.
JMake sure that all operating and service personnel know that in the event hydraulic fluid penetrates skin, it must be surgically removed within a few hours by a doctor familiar with this form of injury, or gangrene, serious injury or death can result. CONTACT A PHYSICIAN IMMEDI-
ATELY IF FLUID ENTERS SKIN OR EYES.
JMake sure all hydraulic hoses, fittings and valves are in good condition and not leaking before starting power unit or using equipment. Check and route hoses care- fully to prevent damage. Hoses must not be twisted, bent sharply, kinked, frayed, pinched, or come into contact with any moving parts. Operate moveable compo- nents through full operational range to check clearances. Replace any damaged hoses immediately.
J Air in hydraulic systems can cause erratic operation and allows loads or equipment components to drop unexpect- edly. Before operating or allowing anyone to approach the equipment, purge any air in the system by operating all hydraulic functions several times after connecting equipment, connecting hoses, or doing any hydraulic maintenance.
Refer to page 11. A hose kit is available that will attach the loader feed lines directly into the rear tractor hydraulic ports. Prepare each hose assembly
(1)by attaching a 90° swivel (2) and male quick- disconnect (3) onto the end of hose (without protector sleeve). Attach the opposite end of the hydraulic hose (with protector sleeve) into the loader feed lines.
Refer to illustration on page 10 for the proper orienta- tion of the hoses.
Connect the end of the hose with the quick disconnect coupler into the female couplers on the rear of the tractor to complete the circuit, as shown in Figure 7.

Once all hoses are connected, start the tractor and run the loader valve lever to check for leaks and purge any remaining air from the hydraulic system.
Check to be sure the valve handle directions correspond with the motion of the loader. See chart on page 11.
Once all hose routings are verified, identify each circuit by placing a matching colored band around the male and female quick disconnect couplers. The color coded bands will make
Attach the plastic tie straps (included in kit) around the hoses to keep them tightly bundled and away from contact with the ground or other moving parts on the tractor or loader. Be sure that adequate slack is left in the hoses so they can move as the loader moves through it’s full range of motion.
Refer to either the 195 or 215 Loader Operator’s Manual to complete the loader installation.
