INSTALLATION: HOLD-DOWN ASSEMBLY (PAGE 11)
SAS™ EXTREME™ AUTO PROCESSOR
GROUND
INSTALLATION OF SAS™ EXTREME™ AUTO PROCESSOR HOLD DOWN ASSEMBLY (HDA):
INSTALLATION SHOULD BE COMPLETED BY AN EXPERIENCED HEAVY EQUIPMENT MECHANIC
AFTER INSTALLATION, PRIOR TO OPERATION
1. Grease all pivot points with Stick and HDA resting on the ground and machine engine off.
2. Stay clear of pinch points. Slowly engage controls. Watch for interference. Stop if interference occurs.
a)
Test up and down
motions of HDA. Due to differences in machines and cylinder control valves, if
down cycle is not smooth, a jerking condition may occur.
Typically this can be rectified by installing simple flow control
valves on the hydraulic lines which feed the extend side of the
dozer cylinders. (Indicated by arrows). (see Hold Down Parts list
on separate page). Two flow control valves are included in parts
kit with Qty 2, SAS Part No. HV-FLW-D-EF30S : Thread #8 NPT
Install flow control valves with fittings between car body frame
hose connection and hydraulic hose. Turn settings to near zero.
Test motion. Slightly open valves uniform amount. Retest. Repeat
until jerking occurs, then turn back to achieve smooth motion.
b)
Test rotational clearance
with HDA raised incrementally higher. Stay clear of pinch points, overhead
electrical wires, and other structures, slowly and cautiously rotate cab and counter weight visually
checking for interference of lower cab and counter weight with HDA lifted at highest level.
Stop if interference occurs.
1. Remove existing dozer blade. Inspect pins and bushings. Replace as needed.
2. Hold Down Assembly (HDA) weight approximately 1,600 kg ( 3,500 LB ).
Eyelets in center of HDA is balance point. If excavator is sufficiently rated to
lift such, align stick with lifting eyelets. Using safe and adequately rated rig-
ging chains, keeping all persons clear, lift HDA off pallet. Move away from
shipping pallet and place on ground with block in place which will allow upper
surface of HDA to be level.
3. HDA should be set level as shown below for staging. Drive excavator up to
HDA and align lower pivot holes in dozer blade mount on excavator with holes
“A” in HDA. Insert and secure pivot pins into assembly.
4. With pivot pins inserted and secure, slowly extend dozer blade hydraulic cylin-
ders to align holes in rod end of cylinder to lift holes “B” in HDA. Keep clear of
pinch points. Insert and secure pivot pins into assembly.
5. Replace any guarding that may have been removed during the removal of the
dozer blade assembly.
SAS has no responsibility as to performance of excavator’s Hydraulic system or
structural adequacy or durability with this attachment.
