CARPET FITTER
MAKE YOUR WRENCH WORK HARDER
The open-ended jaws of a spanner are for use where access is restricted or when fasteners are in
line as in pipework. Use the ring-end of a spanner for initial loosening and final tightening, where
access is available, because it offers maximum strength and grip to reduce the risk of damage to
the nut.
When freeing a ‘frozen’ or ‘rusted on’ nut never use a hammer or extend the length of the span-
ner by using a piece of pipe; you will damage both the spanner and the fastener, instead use a
lubricating oil.
Whether tightening or freeing off a fastening you can apply more power and control by pulling
the spanner toward you and if it accidentally slipped off the nut there is less risk of injury.
For best performance from an adjustable wrench avoid selecting an oversized wrench for the
fastener. Close the jaws of the wrench onto the flats of the nut and then gently move the wrench
forward and back at the same time further tightening the adjusting knurled wheel until the fit to
the nut is without movement; this will minimise damage to the fastener. Always rotate so that the
force is directed toward the fixed jaw.
• Never use a hammer for additional leverage
• Don’t use open-ended spanners or adjustable wrenches to free off a ‘frozen’ nut or to finally
tighten a nut; use a ring spanner instead.
• Keep spanners free from oil to prevent slippage
