USERS MANUAL
Stiff Leg Assembly
Oil stiff leg assembly pivot points and rollers every
two months.
1. Clean dirt from pivot points.
2. Place a few drops of oil at each pivot point and on
roller pins.
Tower Rings
Grease tower rings every six months. Dirt and plastic
dust can accumulate on rings and pedestal ring groves
causing towers to turn hard. Developing a bead of
grease between rings and pedestal ring grooves seals
out much of the dirt and plastic dust.
1. Wipe old grease and dirt from rings and pedestal
ring grooves.
2. Swing towers to one side of machine and position
against mainframe.
3. Use grease gun to apply grease to each grease fit-
ting (2 per ring) on rear half of each ring. Apply
enough grease so a small bead of grease develops
between ring and pedestal ring groove.
4. Swing towers to opposite side of machine and posi-
tion against mainframe. Then repeat Step 3.
5. Swing towers several times to work grease around
rings and pedestal ring grooves. If more grease is
needed, repeat the procedure.
NOTE: If tower still swings hard,
see
Troubleshooting Section — Towers Swing
Hard, Page 16; or, see following segment on
Cleaning Pedestal Ring Grooves.
Cleaning Pedestal Ring Grooves
If preceding procedures will not correct tower(s) that
swing hard, thoroughly clean pedestal ring grooves.
1. Swing towers to one side of machine and bolt towers
to mainframe using tower tie bolts.
CAUTION: Failure to properly bolt towers to
mainframe could result in operator
injury as well as damage machine.
2. Remove upper and lower rear halves of tower ring.
IMPORTANT: Mark each ring's location before
removing and note number and
location of shims that are between
front and rear halves of rings.
Rings and shims must be rein-
stalled in their original locations.
3. Wipe dirt and grease from rings and pedestal ring
grooves. Then wipe ring grooves with a solvent
soaked rag and wipe dry.
4. Apply grease to pedestal ring grooves.
5. Replace upper rear halves of rings and secure bolts
— snug only.
6. Remove tower tie bolts, swing towers to opposite
side of machine and reinstall tower tie bolts secur-
ing towers to mainframe.
CAUTION: Failure to properly bolt towers to
mainframe could result in operator
injury as well as damage to machine.
7. Remove upper rear halves of rings and repeat Step
3 on this side of machine.
8. Apply grease to pedestal ring grooves and to rear
halves of rings.
9. Replace upper and lower rear halves of tower rings
and tighten ring bolts.
IMPORTANT: Rings and shims must be rein-
stalled in their original position.
10. Apply a small bead of grease between rings and
pedestal ring grooves to keep much of the dirt and
plastic dust out of the ring area. See preceding
information on Tower Rings.
Eliminating Air In Hydraulic System
All air has been removed from hydraulic system at the
factory, but if hydraulic system is opened to replace a
system component, it is necessary to bleed air from
system prior to using it.
Bleeding Air In System At Quick Coupler
1. Separate quick coupler.
2. Place male end of quick coupler in container and
hold rag over container and quick coupler.
CAUTION: Wear safety glasses to protect eyes
from hydraulic oil in the event it squirts out
of container and past the rag.
3. Depress ball check at end of quick coupler against
bottom of container.
CAUTION: DO NOT have any pressure on the
system when pressing ball check on quick
coupler.
4. Press up button on control switch to pump air out of
system and continue until only hydraulic oil is being
pumped out.
5. Reconnect quick coupler.
6. Refill hydraulic fluid reservoir to within 1" (25mm)
of top with SUS215 viscosity 100 degrees F (38 C)
10W hydraulic oil or automatic transmission oil
with all other rams or towers fully retracted.
