6280 PROCEDURES
HYDRAULIC FLUID LEVEL
• Machine is run at a low temperature and pressure.
• Check fluid level if there has been a leak, damaged or
ruptured hose or a loose fitting.
• Fluid level should be higher than the Return Line. See
Figure A. Or from the Filler Port, 1'' from the top of the
tank (See Figure B).
• Machines have a fluid level sight window. See Figure
A. The fluid should be in the middle to the top of the
window when the machine is sitting in a normal
operating position without a blade. If your machine
does not have a sight window, fluid should be 1'' from
the top of the tank.
ADDING OR CHANGING HYDRAULIC
FLUID
• Occasionally blow out the Filler Port Cap filter to
remove debris.
• Change or add fluid only when needed.
• To add fluid, unscrew Filler Port Cap from top of
machine (See Figure B).
• To change fluid, remove Filler Port Cap. Remove
drain plug from side of machine (See Figure C). A
container approximately two gallons in size will be
needed to drain fluid into (fluid will not be removed
from hoses).
• Machine has a straining system, but add fluid through
a filter or funnel with a screen to keep fluid clean.
• Use Texaco Rando 46 Hydraulic Oil Light, stock
#6280-1 or comparable.
TANK REMOVAL
