8-2.2. TRIMAST Free Lift Chain
1. Fully lower the lift carriage.
2. Turn off the key switch (6, Figure 12-22 ) and dis-
connect the batteries.
WARNING: Before attempting any adjustment, make
certain power is disconnected.
3. Loosen lower jam nuts (2, Figure 8-1 ), located
above the mounts of cylinder (44, Figure 8-3 ), to
allow for adjustment of middle jam nuts.
4. Break the lower jam nuts (2, Figure 8-1 ), located
below the mounts of the cylinder, free from the
middle jam nuts (2).
5. Take up slack in both lift chains with middle jam
nut (2,
Figure 8-1 ). Strive for equal tension on
both chains.
6. Align anchors (1) so each clevis pin (4) is parallel
to the mast.
CAUTION: At least 3 full threads must be present
below lower nut (2,
Figure 8-1 ) after
adjustment.
7. Tighten jam nuts securely while maintaining align-
ment of clevis pins (4).
8. Reconnect the batteries and turn on the keyswitch
(6,
Figure 12-22 ).
9. Test chain by operating carriage. If slack is still
apparent, repeat above procedure.
8-2.3. TRIMAST Secondary Lift Chain
1. Fully lower the lift carriage.
2. Turn off the key switch (6, Figure 12-22 ) and dis-
connect the batteries.
WARNING: Before attempting any adjustment, make
certain power is disconnected.
3. Loosen jam nuts (2, Figure 8-1 ), the mount of
outer mast (25, Figure 8-3 ), to allow for adjust-
ment of middle jam nut.
4. Break the lower jam nuts (2, Figure 8-1 ), located
below the mount of outer mast free from the mid-
dle jam nuts.
5. Take up slack in both lift chains with middle jam
nut (2). Strive for equal tension on both chains.
6. Align anchors (1) so each clevis pin (4) is parallel
to the outer mast (25,
Figure 8-3 ).
CAUTION: At least 3 full threads must be present
below lower nut (2,
Figure 8-1 ) after
adjustment.
7. Tighten jam nuts securely while maintaining align-
ment of clevis pins (4).
8. Reconnect the batteries and turn on the keyswitch
(6,
Figure 12-22 ).
9. Test chain by operating carriage. If slack is still
apparent, repeat above procedure.
8-3. LIFT CHAIN WEAR INSPECTION.
Both lift chains should be replaced when either chain
is worn enough to increase it’s length by 3% or more.
To make this determination proceed as follows.
Using a section of chain that sees the most frequent
operation over the chain sheaves, isolate a vertical
portion under tension from the weight of carriage and
forks.
Measure the distance between pin centers on 20 verti-
cal links. If the section measures 12.88” or more, the
chain should be replaced.
New chain anchor pins should be installed when
chains are replaced. Never replace a partial section of
chain and never repair chain. Refer to paragraph
8-4.
when installing new chain.
