The handle attachment may havesuffered wear and tear but wehave
to ensure it is in good condi-tion both comfortable and quietto use
for hours at a time.
(1) Remove the machine from its case. The handle arm will will
be folded down.
(2) Place the handle in its working position by lifting the arm
and clicking into place. To release pull the small spring stud.
On older machines, the handle isheld in the latched position by
apin inside the bracket, ratherthan the spring stud.
If the spring inside the bracket isbroken and the pin does not
holdthe handle arm in position, eitherchange the handle from
anyspares you may have, or note iton the refurbishment record onthe
outside of the case and NetleyMarsh will change it.
Make sure the wooden handle isfree from worm or splits andturns
freely on the spindle. If it isstiff apply some penetrating oiland
leave for a while.
Check that the wooden handle isturning on its spindle, not
thatthe spindle is turning with it. Thespindle should be securely
heldin the crank handle lever, neitherturning with the wooden
handle,nor being loose.
(3) A possible solution to correct this problem is torest the
end of the handle
on a metal object andtighten the joint using apunch and
hammer.
If the handle is in poor conditionor refuses to budge, it could
bemore productive to exchange itfor a better quality spare unit.
Ifyou dont have a spare, highlightthe problem on the refurbish-ment
record on the outside of thecase and we will replace the unitfrom
our stock at Netley.
It is worth noting that some han-dle units vary in size and are
notinterchangeable between differ-ent models. In particular,
thebracket length varies. If youchange handles between models,make
sure that the driver armengages with the balance wheelwithout
fouling the bobbinwinder when it is latched down.
(4) Detach the handle mechanism from the machine body by undoing
the single screw bolt.
The machine you are working onhas probably stood idle for
anumber of years and the oil in thehandle gear housing may
havebecome gummed.
(5) Remove the cover plate to reveal the internal gear mechanism
and make sure the workings are clean and free from grime and any
odd bits of lint or thread.
After cleaning, turn the handleslowly through a complete turn.If
there is resistance at any point,examine the teeth and clean outany
debris.
Apply a drop of oil before replac-ing the cover plate. There are
oil-ing holes in both the drive armand the main gear. Apply a
dropof oil to each and run for a fewturns.
(6) Hold the reassembled unit inyour left hand and ensurethe
whole mechanism runs smoothly and easily.

(7) See that the small hinged flap on the rear drive arm turns
back easily and is properly cushioned.
This flap locates between thespokes of the balance wheel
andengages the machine ready foruse.
(8) Older machines have a thinleather sleeve on the end of
thehinged flap to cushion andsilence the action. If the leather
isworn out or missing the machinewill be noisy.
(9) To re-cushion the hingedflap, trim off any excessleather and
press a tight fittingsmall piece of plastic tubing over the
arm.
(10) More modern machineshave a fibre pad with a smallmetal
plate and screw to hold itin place.
If the pad is missing or badlyworn, replace it if you have
anyspares. Otherwise, note it on therefurbishment record on the
out-side of the case and Netley Marshwill change it.
Put the refurbished handlemechanism with its fasteningscrew to
one side until the rest ofthe refurbishment has beendone.
