LOADMASTER LEGACY 3 Series, Preventive Maintenance Manual

Page: 22 / 25

11 REPLACE THE TANK’S FILLER/BREATHER…YEARLY
There is a media inside this breather that will trap-out
airborne dirt. This inexpensive unit is a “throwaway”
part, don’t bother trying to clean it…just get a new one
from LOADMASTER and replace it. This breather is also
your oil fill neck and has a wire basket to stop big stuff
from falling into the tank when opened.
12 REPLACE THE HYDRAULIC FLUID…ONCE EVERY
OTHER YEAR
This would be the minimum change-out frequency. A
yearly change-out would be better. Modern hydraulic
fluids have additive and lubricity packages that will
deplete and wear down overtime. Always replace your
hydraulic fluid when you are doing a “pump change-out”
(along with a new return filter and suction filter).
Replace your hydraulic fluid if you had a “contamination
experience” such as a seized valve spool or if it has a
milky (water contaminated) appearance.
13 PRESSURE WASH THE UNIT TO REDUCE FIRE
RISK…WEEKLY
Well, at least once a month. Allowing any hydraulic fluid
to accumulate will make putting out any fires much
more difficult and also be a possible fire origin spot. A
clean LEGACY3 tends to be a better-maintained and
safer LEGACY3.
14
GREASE THE CONTROL RODS PLASTIC
BEARINGS…WEEKLY
If a lot of mechanical drag exists in the controls for the
valves that have the knockout positioners, it may cause
them to operate erratically. A regular greasing also
forces out (displaces) moisture that can attack the steel
shafting (corroding and pitting), thereby causing even
more drag. Sometimes, what is thought to be a
hydraulics problem is really a mechanical control
problem.
