Changing the Saw Blade
Put the table back to the level position if it has been tilted.
Move the motor brake selector switch to position (1), see fig 85
and 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 87, 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.

WARNING! BE VERY CAUTIOUS WHEN
YOU 'UNFOLD' THE BLADE; IT TENDS TO
'SPRING' OPEN, BLADE AND TEETH
GOING EVERYWHERE.
Also check that the blade did not "unfold" inside out. i.e. looking
at the right side front of the loop, the teeth should be on the
front of the blade and pointing down. If you can't arrive at this
view, turn the blade inside out from its current position and
look again.
MAKE SURE THE BLADE TEETH ARE
POINTING DOWN!
Open up all blade guides so that they are clear of the blade.
Hold the blade approximately midway on either side of the
loop and feed it into the table slot. When you get to the table
insert cutout void, work the left side of the loop into the slot in
the guard in the neck of the main saw frame. 'Wriggle' the right
hand side of the blade through the slot in the lower bearing
guide guards and through the guard on the upper blade guide
assembly, see figs 88-89-90.
