PREOPERATION PROCEDURES
DAILY MAINTENANCE CHECKS
Check for loose or missing fasteners. Tighten or replace
as needed. See Torque Specications in the ASSEMBLY
section of this manual.
Check to be certain that the ow control valve on the car-
rier is set to the proper ow for the compactor. See the
SPECIFICATIONS section of this manual.
Check shock mounts for cracks or tears. Rotate shock
mounts 180° when fatigue tears begin to show at top outer
crease of the shock mount. This will prolong the life of the
shock mount.
Check for abrasion and hydraulic leaks at ttings and hos-
es. Replace defective hoses and ttings. Adjust hoses
and tighten ttings so the hoses do not deect into contact
with structure during use.
DO NOT USE BARE HANDS TO CHECK OR SEARCH
FOR HYDRAULIC LEAKS AROUND HOSES AND FIT-
TINGS. PINHOLE LEAKS CAN PENETRATE THE SKIN.
TO INSPECT FOR LEAKS, DEPRESSURIZE THE SYS-
TEM, CLEAN AROUND SUSPECTED AREA, REPRES-
SURIZE THE SYSTEM, AND VISUALLY CHECK FOR
LEAKS.
Lubricate bearings with two pumps of grease every 40
hours of operation. A greasing location is provided in both
bearing carriers.
Inspect pins and bushings for correct t and lubrication.
Check level of hydraulic reservoir on carrier.
Make certain that quick couplers are fully engaged and
leak free.
PRE-INSTALLATION INSTRUCTIONS
Test the carrier hydraulic system to verify that the system
is operating at the manufacturer's specied capacity and
pressure ratings.
Be sure the uid and lter in the hydraulic system are
clean.
When tightening pipe threads, be careful that any seal-
ant used (Teon ® tape, etc.) does not enter the hydraulic
system. Foreign matter introduced into the system may
damage hydraulic valves, motors and pumps.
Follow instructions to install the Stanley priority valve in
the carrier hydraulic system. the warranty is in effect only
if the valve and compactor are installed as outlined in the
valve kit installation instructions. Major modications or
equipment substitution will cause the warranty to be void
unless prior engineering approval has been granted by
Stanley Hydraulic Tools.
The Stanley priority valve is a metering (to the hydraulic
tool) pressure compensating valve that controls the ow
to the attachment and gives the primary system (i.e. back-
hoe functions) full operating pressure. Diverter valves or
simple ow control valves will not perform all of these re-
quired functions.
Note:
On carriers where priority valves are not used, check
with your local Stanley distributor for an adapter kit to
equip your carrier for a specic model of compactor.
LOW-TEMPERATURE WARM-UP PROCE-
DURE
When the weather gets cold, the shock mounts on com-
pactors can become stiff. In severe weather, where the
ambient temperature is below freezing for extended peri-
ods, shock mounts can even become brittle. Therefore, it
is necessary to warm the shock mounts prior to using the
compactor. To warm the shock mounts follow these steps:
1. After starting the carrier, warm up the system until hy-
draulic lines are warm to the touch.
2. With the carrier at idle, place the compactor at on the
ground, and using a slight down pressure to keep the com-
pactor in place, turn the compactor on. DO NOT place a
load on the compactor during this procedure.
3. When the ambient temperature is below freezing, the
compactor should be operated on the ground with a slight
down pressure (no load) for at least one minute before
putting it to work.
