Check fabric. Weak or torn areas may be
repaired by a cement patch or machined
patch. All material used to repair the cover
must be the same as the original material.
Check strength of fabric. Grasp a small fold
of fabric between thumb and forefinger of
each hand, gripping it closely so tips of
forefingers touch. Tug material several times.
If it does not rip, it is reparable. If it tears
on first tug, test several areas for extent of
wear. Weak sections must be replaced.
Check for spots and stains. Nonwear spots
and stains are all right if fabric has been
brushed clean. Repair fabric where fabric
strength has been weakened by mildew,
sap, or dirt stains.
Check fabric. Repair opened seams, runoff
stitching, and broken threads. Restitch worn
Check webbing straps. Repair or replace
worn, frayed, or torn straps.
Check buckles. Replace buckles that are bent,
broken, or missing.
Check for slide fasteners (zippers). Replace
zippers that are rusted or do not work
