Changing the Saw Blade
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 and remove the table insert.
Remove the table stabilising bolt, release the blade
tension by pulling the quick release lever towards you,
see fig 83, the blade can be easily slipped off the wheels.
Remove the blade carefully, ‘wiggling’ it clear of the upper
blade guard and through the plastic lower 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 threads of the blade and drive belt tensioners and
the tracking control. The pivots and the slides of the top
wheel mounting assembly and the captive stub axle of
the drive belt tensioner in its slot could likewise be lightly
oiled. If you are fitting a new blade, it will have been
supplied to you “folded”, bound together in this
configuration with tape or tie wrap.
1. Make sure you have read and fully understood the
general instructions and safety precautions in the
preceding pages of this manual.
2. Before connecting the machine to the supply; check
the machine for obvious signs of damage, paying
particular attention to the plug and the power cable.
Check that the blade you are using is the correct one
for the job in hand. Change the blade if necessary.
Check the blade is not damaged; is clean, sharp, tracks
properly and is correctly tensioned.
3. Set the upper blade guide to approximately 12mm
(1/2”) above the height of the work piece.
4. Check there are no foreign objects e.g. old nails,
screws, small stones etc embedded in the material you
are about to cut.
5. Remove all accessories, tools etc., that have been used
to set the machine.
6. Ensure the machine is switched off. Plug the power
cable into a correctly rated switched socket outlet. If
extension leads are being used, check these for
damage, do not use if damaged. Switch on. Allow
the saw to run up to speed.
7. Make sure that the material you are about to cut is
within the machine’s capacity, and the cut you are
about to make is within the blades’ capabilities, e.g.
do not try to cut a 1” radius curve using a 5/8” blade.
8. Make sure the blade is not in contact with the material
when you start the saw. Do not try to cut too quickly;
the correct cutting speed, would never see the blade
pushed back against the thrust be aring, 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, chances are the blade
is becoming blunt. Check and change if necessary.
9. 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.
10. 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.
11. Observe the old woodworkers’ adage of never
allowing your hand/fingers within one
handbreadth of the blade.
12. If you have to cut very small pieces of material,
use a push stick.
13. Remember to check the blade tension after a new
blade has been ‘working’ for 30-60 mins. The blade
will ‘stretch’ slightly when new.
14. 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 constant changes in stress
and tension. Only release the tension to change the
blade or once work has finished for the day.
The blade in tension over a long period of non-use
will cause the tyres to develop ‘flat’ spots.
WARNING! IF THE SAW JAMS!
SWITCH OFF IMMEDIATELY.
