attention to the oil hole and groove in the bar, and the oil nole
in the bar mount on the machine
3 Check the guide bar for wear Remove light burrs with a flat file;
heavy burrs mean 'replace' - see next column
4 Oil the sprocket spindie with a few drops of chain oil, and
check that the sprocket isn't badly worn If it is, see return'.
5 Re-assemble the guide bar and chain, fitting the bar the
other w ay round.
This w ill distribute the wear evenly around the guide bar rails.

use
Saw Chain Sharpening
Sharpen the chain at regular intervals to get the best out of it
You w ill need a Black & Decker saw chain sharpening kit (see
'Accessories']
On each tooth, this is the cutter
and this is the depth-gauge, lim iting the depth ot cut to this
1 File from the inside to the outside of the cutters only
2.
Put the file-holder with its tile on a cutter, keeping thisjine
parallel with the chain ^

Make sure that the replacement is a
safety chain, and remember to soak it in chain oil for an hour
before fitting it See Accessories' for suitable chains
•
The guide bar with every second new chain, and at any
time it there is
-- spreading of the rails giving a very wide groove.
- uneven rail wear,
- heavily worn rails giving a shallow groove;
. - cracking of the bar surface This is due to overheating
caused by lack of oil
Return
your saw to Black & Decker tor replacement pads to be fitted
if - the sprocket is badly worn,
or - the cable is in poor condition
You should not dismantle
the machine other than as described in this leaflet
4 Sharpen all the cutters on one side, then move to the other side
of the saw and file the rest
D epth gauges
Check depth gauges every third sharpening You will need a
medium-grade flat file as welt as the filing gauge in the '
sharpening kit
1.
Put the filing gauge on the chain over each depth gauge in turn
2.
If a depth-gauge protects, file it level
3.
Finally, round oft the corners of the depth-gauges
