Inspect Parts Every Time You Sail
Inspect secondary lashing
at head of block to make
sure knot and stop knots
are holding tightly.
WARNING! Failure to inspect and correct block, and loop
or lashing can result in block breaking under load. Inspect
parts each time you sail. If parts are under load during long
passages, it is important to inspect them carefully while
in use.
Replace loops or lashings if there are signs of wear or if the colored tracers
fade from UV damage. Fading tracers indicate general UV degradation. Pull
loop out of mouth and inspect loop/lashing carefully for any signs of wear,
UV damage, fatigue, or strand separation. Replace loop if it shows signs of
UV damage or wear.
WARNING! Failure to replace damaged or weakened parts can
cause part to break under load. Replace all loops and lashings
every year, or if there is any sign of wear, UV damage, fatigue
or strand separation. If in doubt replace. Consult chart to match
strength of loop/lashing to block and load.
Disassemble using inner
race cutouts and split in
cage. IMPORTANT! Do
not force bearing cage.
See last page for details.
Lightly grease inner

Short Term Maintenance
Flush block and attach-
ments frequently with
detergent and fresh water.
Clean bearings by flushing
areas shown while rotating
sheave.
WARNING! If secondary lashing at head comes loose, block can
flip and cause line to jam, resulting in loss of control. Inspect
lashing often and redo if necessary.
Long Term Maintenance
