3-4 LIFT CHAINS AND SLIDE BLOCKS
WARNING
Do not operate a unit on which any chain assembly is damaged or in need of re-
placement. Operating a unit with a damaged chain can cause severe injury or
death to personnel and damage to equipment.
Inspect all lift chains daily. Inspect for signs of wear, split leaves, loose pins, clevis dam-
age, and elongation. Replace any chain which is damaged in any way. Chain assemblies
may be ordered from your dealer or direct from the factory. Do not operate a unit on
which any chain assembly is damaged and in need of replacement.
Chain Elongation Inspection
One pitch of chain should measure 5/8 in. (1,5875 cm). Measure 20 pitches of chain. The
ideal measurement for 20 pitches of chain should be 12.5 in. (31,75 cm). Replace the
chain if 20 pitches measure over 12.75 in. (32,385 cm). Refer to Figure 3-4.

NOTE: It is recommended that chains be replaced every four years unless dam-
age or wear requires replacement at a lesser interval.
