3ASSEMBLY PROCEDURES
It is very important that your new DR8700 Fold
Series Disc Ripper be properly assembled, ad-
justed, and lubricated before use. Illustrations to
assist with the assembly process are provided in
Section 2, “Standard Specifications”. Illustra-
tions are provided in this section to show proper
shank, disc gang, and mounting bracket spacings.
Remove paint from grease fittings and replace any
that are damaged or missing. Be sure to replace
bolts, clips, etc. in the same place from where they
were removed.
To insure assemblies are aligned, insert all
bolts and leave the nuts loose until completion
of final assembly. Use lockwashers or flat wash-
ers where called for. Spread all cotter pins.
After completion of final assembly, tighten all
nuts evenly to prevent misalignment, distortion, or
binding. Tighten all bolts and nuts to the recom-
mended torques shown in Table 2-1, “Standard
Bolt Torques.”
DANGER
DISC BLADES ARE EXTREMELY
SHARP. EXERCISE EXTREME CARE
WHEN WORKING ON OR NEAR DISC
BLADES. DO NOT ALLOW DISCS TO
ROLL OVER OR FALL ONTO ANY
BODILY PART. DO NOT ALLOW
WRENCHES TO SLIP WHEN WORK-
ING NEAR DISC BLADES. NEVER
PUSH WRENCHES TOWARD DISC
BLADES. DO NOT CLIMB OVER MA-
CHINE ABOVE DISC BLADES. FAIL-
URE TO STAY CLEAR OF DISC
BLADE EDGES CAN CAUSE SERIOUS
PERSONAL INJURY OR DEATH.
WARNING
DO NOT ATTEMPT TO LIFT HEAVY
PARTS (SUCH AS THE FRAME, DISC
GANGS, ROCK SHAFT, AND PULL
HITCH) MANUALLY. USE A HOIST OR
A FORK LIFT TO MOVE THESE
PARTS INTO POSITION.
DANGER
TO PREVENT ACCIDENTAL LOWER-
ING:
1. ALL HYDRAULICALLY ELEVATED
EQUIPMENT MUST BE LOCKED OUT
USING THE CYLINDER LOCKOUTS:
2. LOWER EQUIPMENT TO THE
GROUND WHILE SERVICING OR
WHEN IT IS IDLE.
FAILURE TO TAKE MEASURES TO
PREVENT ACCIDENTAL LOWERING
MAY RESULT IN SERIOUS PER-
SONAL INJURY OR DEATH.
CAUTION
BE SURE DEPTH STOPS ARE EQUAL
LENGTHS ON ALL CYLINDERS. US-
ING UNEQUAL DEPTH STOP
LENGTHS CAN CAUSE PERMANENT
EQUIPMENT DAMAGE.
CAUTION
BE SURE TO BLEED THE HYDRAU-
LIC SYSTEM OF ALL AIR IN LINES
AFTER INSTALLATION. FAILURE TO
BLEED THE SYSTEM OF ALL AIR
CAN RESULT IN IMPROPER MA-
CHINE OPERATION.
