CHECK THE OIL TANK’S FILL LEVEL…DAILY 

 

The tank has a sight level gauge that is used to confirm 
the correct amount of hydraulic fluid is in the system. 

 

Checking procedure: 

1-

 

Retract the ejector blade fully forward towards cab. 

2-

 

Tailgate fully lowered closed and latched. 

3-

 

The slider cylinders must be fully retracted (slider fully up) 

and sweep cylinders fully retracted (sweep rotated up). 

4-

 

PTO disengaged (diesel can be on or off). 

5-

 

Now  read  the  tank’s  fill  level  gauge.  The  amber  colored 
hydraulic oil’s level should be visible 

6-

 

Fill to the upper black line (with all cylinders retracted).

 

 
DO NOT 

OVERFILL

 THE TANK. Oil will spray out of the 

tank’s filler/breather if overfilled. 
 
Be certain to position the ejector, tailgate, and compact 
blades  are  as  described  above 

before

  sighting  the 

gauge. This will position the “cylinders” to assure you do 

not overfill. 

 

Use  a  name  brand  hydraulic  fluid  in  an  AW46  grade 

whenever you add fluid.

CHECK  THAT  THE  SUCTION  LINE  VALVE  (GATE 

VALVE) IS FULLY OPEN…DAILY 

 
The leverarm of the full-port ball valve must be “parallel” 

to its body to be fully open

CHECK 

THE 

“PLUMBING” 

FOR 

EXTERNAL 

LEAKS…DAILY 

 
Hydraulic fluid is flammable and messy. When fluid is on 
the  shop  floor  or  on  the  LEGACY3  it  can  cause  injuries 

from slipping and falling. Inspect the LEGACY3’s various 
fittings,  hoses,  tubes  for  any  evidence  of  oil  escaping. 

Often by retorquing the hose end or fitting you can stop 
the leakage. Sometimes a hose or fitting will need to be 
replaced. 

 

5

 

CHECK  THE  PUMP  AND  VALVES  FOR  EXTERNAL 
LEAKAGE…DAILY 

 
The  LEGACY3  uses  “0-ring  boss”  ports  on  all  the  valve 

ports and the pump. Leakage here is usually going to be 
correctable  by  retightening  the  attached  fittings.  In 
some rare cases the o-ring may be nicked or extruded, 

replace the o-ring or install fresh fitting. The valves have 
a  group  of  o-rings  seals  between  their  cast  sections.  If 

oil seems to be weeping out between sections, try to re-
torque  (evenly)  the  valve  tie-rod  bolts  first  (loosen 

valve’s mounting foot  bolts first). The pump  has  a seal 
on  its  input  shaft  that  could  eventually  weep  oil.  This 
must be replaced if this is happening. 

 
The most difficult job in fixing a leak is identifying where 

the oil is 

really

 

escaping. Gravity, road travel blow-age, 

etc  can  fool  you  into  misidentifying.  If  in  doubt,  wash 
area and keep looking until confident. 

 
6

 

CHECK  THE  ROD  CYLINDERS  FOR  EXTERNAL 

LEAKAGE…DAILY 

 

Rod cylinders have a bearing and seal system where the 
rod  itself  leaves  the  barrel.  Repair  if  leakage  occurs 
here. 

 
7

 

INSPECT THE STEEL TUBE RUNS FOR DAMAGE AND 

LOOSE CLAMPING…DAILY 

 
If  a  tube  is  impacted,  it  may  become  damaged.  Check 

for this. Replace damaged  tube so they do not  rupture 
later. 

 
8

 

CHECK  FOR  A  FULLY  CHARGED,  ACCESSIBLE  FIRE 
EXTINQUISHER…DAILY 

 
Hydraulic fluid is flammable and could ignite if it sprays 

upon the diesel’s hot exhaust surfaces. 
 

9

 

INSPECT  THE  HOSES  FOR  ABRASIONS,  RUB 
SPOTS,ETC…DAILY 

 

Identifying  possible  hose  weaknesses  and  repairing 
them promptly will reduce the possibility of a hose burst 
later on. 
 
10

 

REPLACE 

THE 

IN-TANK 

SUCTION 

STRAINER…YEARLY 

 

Near the floor of the oil-tank (submersed) is the suction 
filter/strainer. Whenever the tank has been drained of oil 

(for  whatever  reason),  remove  this  filter  and  replace  it 
(or  clean  it  if  in  otherwise  good  condition).  Make  sure 
the  3-PSI  bypass  valve  is  “free”  and  will  fully  seat 

closed.
