P-M… SAFETY SYSTEMS AND 

OVERALL LEGACY “3” 

 

1 & 2 CHECK THE BACKUP ALARM TO BE IN GOOD WORKING 
CONDITION...EVERY DAY 

 

The LEGACY3 has a back up alarm (grommet mounted) in the upper 
“light  bar”.  This  backup  alarm  is  wired  to  sound 

not  only  with  the 

transmission in reverse, but also whenever the tailgate raises up about 
a foot above fully closed. Repair this important system immediately if it 

does not “sound” when (a) the tailgate is raised upward about a foot 

or  (b)  when  the  chassis  transmission  is  shifted  into  reverse.  See  the 

Table  of  Contents  to  locate  the  wiring  schematic  to  aid  in 

troubleshooting this system.

CHECK  THE  “DRIVER  SIGNALLING  BUZZERS”  TO  BE  IN 
GOOD WORKING CONDITION…EVERY DAY 

 

There  are  two  “button  switches”.  One  switch  is  on  the  left  side  of 

tailgate and one on the right side of tailgate. They are labeled “driver 
signal”. One “buzzer” is mounted under the dash and is controlled by 

either  “driver  signal”  switch.  Repair  immediately.  See  Table  of 
Contents  for  wiring  schematics  to  aid  in  troubleshooting  this  signal 

system.  The  wiring  scheme  is  for  either  of  these  switches  to  “make 
ground”. 

 
4

 

CHECK  THE  SIDE  STEPS  TO  BE  SECURELY  ATTACHED, 

FLAT 

AND 

STRAIGHT, 

AND 

NOT 

IMPACT 

DAMAGED…EVERY DAY 

 

LOADMASTER  has  these  fabricated  steel  parts  listed  in  the  PARTS 

MANUAL. Repair or replace these steps as needed. 

 

5

 

CHECK  THAT  THE  VARIOUS  LIGHTS  AND  SIGNALS 
NEEDED  FOR  SAFE  STREET  TRAVEL  ARE  IN  GOOD 
WORKING CONDITION…EVERY DAY 

 

Some of these lights are mounted to the LEGACY3 body and some are 

a part of the chassis. See the Table of Contents for wiring diagrams (if 
needed) to troubleshoot a wiring problem. Most often a simple “lamp” 

(bulb) replacement is needed. 

 

6

 

CHECK THAT THE “GATE AJAR” IN-CAB PILOT LITE IS IN 
GOOD WORKING CONDITION…EVERY DAY 

 

This  “gate ajar” light will properly illuminate whenever  the tailgate is 

raised up about 1-2 foot. There is a wobble-stick switch located at the 
tailgate to body hinge on driver’s side of body (left side). This wobble-

stick limit switch’s  job is to control the “gate ajar” pilot light. This pilot 
light is the only light mounted in the “rocker switch” panel in the cab. 

The wobble-stick limit switch is wired NC (normally closed) and is held 

open when the tailgate is almost fully down. See Table of Contents to 
locate the wiring schematic to help trouble shoot. 

 
7

 

CHECK  THAT  THE  GRAB  HANDLES  ARE  SECURELY 

ANCHORED…EVERY DAY 

 

Look for any evidence of structural cracks. Repair if needed. 

 
8

 

CHECK  THAT  THE  BODY  ACCESS  DOOR’S  LADDER, 

HINGES,  AND  LATCH  ARE  IN  GOOD  CONDITION…EVERY 
DAY 

 

The ladder’s fasteners must be snug and the hinges not worn. Once a 

month  a  little  grease  on  the  slam-latch’s  bolt  will  assures  a  good 
action. Repair worn or failed parts. 

 

9

 

CHECK  THE  INFORMATIONAL  DECALS,  THE  SAFETY 
DECALS  AND  OTHER  LABELS  TO  BE  READABLE,  CLEAN, 

AND IN GOOD CONDITION…EVERY DAY 

 

Make  a  photocopy  of  the  decals  shown  in  this  manual.  Walk  around 
the  LEGACY3  and  circle  in  red  any  that  need  replacement. 

LOADMASTER has them in stock. Replace immediately. 
 

If you repaint either mask-off the decals or order a complete fresh set 
from LOADMASTER. They are not particularly expensive.

 

 
10

 

CHECK  THE  HYDRAULIC  SYSTEM  FOR  ANY  EXTERNAL 

LEAKS…EVERY DAY 

 

Hydraulic  fluid  is  flammable  and  messy.  It  can  cause  people  to  lose 
good footing and  fall… on the  LEGACY3 and on the shop floor.  Look 

for leaky connections, pump shaft leaks, valve leakage, etc and repair 
immediately. 

 

Check  the  hoses  for  rubout  spots  that  can  later  cause  sudden  hose 
failure.  Check  the  steel  tube  runs  for  impact  damage.  Repair 

immediately.

 

 

11

 

CHECK THAT THE KNOBBED HAND LEVERS MOVE FREELY 
AND  RETURN  FREELY  TO  THEIR  CENTERED-NEUTRAL 

POSITONS…EVERY DAY 

 

The  two  hand-levers  at  the  body-mounted  valve  (tailgate  raise/lower 

and ejector extend/retract) are spring-centered. Make sure the spring 
itself (by itself) can return the spool to neutral-centered position. If the 

operator  must  add  his  own  force  to  get  to  neutral,  the  spool  needs 

repair.  The 

option  hand  levers  of  the  tailgate-mounted  valve  are  the 

same  types  of  operation…spring-centered.  The  two  controls  for  the 

hopper  blades  (sweep  and  slide)  have  knockout  positioners  that 
properly “hold” the spool shifted, then release when pressure rises to 

their pressure settings. 

 

Troubleshoot  and  repair  any  spool  operation  that  is  not  as  described 
above. 

 
12

 

CHECK  THAT  THE  LEGACY3  ITSELF  AND  THE  TRUCK 

CHASSIS ARE CLEAN AND FREE OF DEBRIS…MONTHLY 

 

Actually make sure it is clean EVERY DAY. LOADMASTER suggests you 
pressure wash the LEGACY3 

at least MONTHLY. A weekly wash is even 

better.  Keeping  your  LEGACY3  clean  will  promote  paint  durability, 
significantly reduce your fire risks, reduce slippery hands and feet, and 

give the truck’s operator a sense of order and professionalism. Also, all 
of  the  service/maintenance  people  will  then  have  better  working 

conditions. Stale garbage matter is foul and nasty. 
 

Some debris will “blowby” the ejector blade settle on the cab’s side of 
the  ejector.  Shovel  this  debris  to  the  outside  once  a  week.  Always 

“park”  the  ejector  blade  fully  rearward  (towards  the  tailgate)  before 

entering the body. 

 

DANGER…Shutdown the diesel and place the ignition keys in 

your pocket before entering the body access door! 

 
When  pressure  washing,  do  not 

directly  “blast”  the  electrical 

components  such  as  the  various  switches…you  may  water  damage 
them. 

 
When  pressure  washing,  always  keep  both  feet  squarely  on  the 

ground. The LEGACY3’s painted steel surfaces will become extremely 

SLIPPERY when doused in soapy water! 

 

Shutdown  the  diesel  and  place  the  ignition  keys  in  your 

pocket before doing any cleaning.
