Changing The Saw Blade - Axminster HBS200N Manual

Operating Instructions
Do not try to cut too quickly; the correct cutting
speed, if one could be so precise, would never see
the blade pushed back against the thrust bearing.
The saw would cut and clear the saw line at the rate
the work piece was fed into it. If you notice that you
require more and more pressure to effect the cut,
and the blade is in continual contact with the thrust
bearing, the chances are the blade is becoming blunt.
Check and change if necessary.
Do not let go of the work piece; if you have to change
your grip, make sure one hand is holding the material
at all times.
9. If you are cutting long pieces of material think
about sawing cutouts (i.e. a saw cut from the edge
of the material to the saw line) along the saw line
so that you can discard the off cuts as you progress
down the saw line.
10. Observe the old woodworkers' adage of never
allowing your hand/fingers within one handbreadth
of the blade.
11. If you have to cut very small pieces of material,
arrange or manufacture some form of 'shoe' to carry
the timber. If the work piece is exceptionally small,
find something to use as a sacrificial carrier and
mount the work piece on it with double sided tape,
or similar.

Changing the Saw Blade

DISCONNECT THE SAW
FROM THE MAINS SUPPLY!
Put the table back to the level position if it has been
tilted. Set the upper blade guide assembly
approximately midway in the throat. Open the top
and bottom covering doors. Remove the fence and
guide rail and place safely aside. Slacken the blade
tension by turning the blade tensioning wheel
anti-clockwise, until the blade can be easily slipped
off the wheels, see fig 30.
Remove the blade carefully, "wriggling" it clear of the
upper blade guard, and out through the slot in the
table. NOW is an excellent time to clean out the
interior of the machine, remove the impacted 'crud'
from the tyres, apply a little light oil to the screw
12. Remember to check the blade tension after a
new blade has been 'working' for 30-60 mins. The
blade will 'stretch' slightly when new.
13. Do not release the tension on the saw blade
when work is complete. The blades and the main
saw frame do not respond kindly to frequent large
changes in stress and tension. Only release the
tension to change the blade or if the blade is to be
removed because the machine is to be 'mothballed'
for a lengthy time period.
The blade in tension over a long period of non-use
will cause the tyres to develop 'flat' spots. Open the
saw cut, either by pulling apart or driving a wedge
in close to the back of the blade. Try to "wriggle" the
blade free of the saw. If this is not possible; check
that the saw is free in the cut, start the saw, allow it
to run up to speed and 'cut out' as quickly as possible.
The removal of the 'off cut' may well prevent the saw
jamming again if you resume the original cut.
WARNING! IF THE SAW JAMS!
SWITCH OFF IMMEDIATELY.
Slacken the blade by turning the
tensioning wheel anti-clockwise
threads of the blade tensioner, and the tracking
control. The pivots and the slides of the top wheel
