Hydraulic Installation

Never modify or alter any of the equipment, whether mechanical, electrical, or hydraulic, 
without Stellar Industries’ approval.

Do not touch or grab any hoses that could be under pressure.  Release 

system pressure before attempting to make adjustments or repairs.

Do not attempt service or repair when PTO is engaged.

Disassemble and assemble hydraulic components on a clean surface.

Clean all metal parts in a nonflammable cleaning fluid.  Then lubricate all components to 
aid in assembly.

Hydraulic fluid expands when heated.  This raises the pressure in an 

unventilated tank.  Release the tank pressure before removing the cap completely.  Failure 
to do so may cause the oil to shoot out of the tank very rapidly and cause severe burns.

Do not rely on the hydraulic fluid to support the boom or crane.  If 

hydraulic fluid escapes, the boom or crane can fall immediately.  Make sure the ground or 
blocking is supporting the boom before performing any maintenance or repair. 

Contaminants in a hydraulic system affect operation and will result in 

serious damage to the system components.  Dirty hydraulic systems are a major cause of 
component failures.

If evidence of foreign particles is found in the hydraulic system, flush the system.

When installing metal hydraulic tubes, tighten all fittings finger tight.  Then , in order, tighten 
the fittings at the rigid end, the adjustable end, and the mounting brackets.  After tubes 
are mounted, install the hoses.  Connect both ends of the hose with all fittings finger tight.  
Position the hose so it does not rub the machine or another hose and has a minimum of 
bending and twisting.  Tighten fittings in both couplings.

Due to manufacturing methods, there is a natural curvature to a hydralic hose.  The hose 
should be installed so any bend is with this curvature.
