exactly in the centre of the tyre. This adjustment
is effected by turning the Tracking Adjuster Knob
(J, Fig. 11).
Screwing ‘in’ (clockwise), will cause the upper
wheel to tilt inwards at the top slightly, which in
turn causes the blade to run on the front of the
wheel. Screwing anticlockwise, has the opposite
effect.
The sequence of adjustment is as follows:
Ref: Fig’s. 12 and 13
1. Apply tension to the blade by screwing the
tension adjuster knob clockwise until the blade
feels firm on its’ run between the two wheels.
2. Turn the upper wheel clockwise, by hand, and
observe the reaction of the blade, and its
position on the tyre of the upper wheel
3. If the blade begins to move towards the front
edge of the tyre, (i.e. towards you as you look
at it), slowly turn the adjuster knob anti-
clockwise, causing the upper wheel to tilt
outwards at the top, thereby causing the
blade to move further towards the back edge
of the tyre. Conversely, if the blade tends to
run towards the back edge of the tyre, turn
the alignment knob clockwise.
Tracking is correct when the blade runs
precisely in the middle of the wheel.
NOTE:
Should you have difficulty in moving the tension
adjuster, it is possible that the Guide Screw, (arrowed
in fig 14) is too tight. Slacken it off slightly using the
Hex. wrench supplied, to free off the mechanism. Do
not leave this screw too loose, it should be firm, but
the trunnion must be free to move up and down.
When tracking is correct, it is necessary to adjust
the Blade Guides as follows:
B. Blade Guide Adjustments.
(Ref Figs 12 & 13)
NOTE:
a. Blade Guides should be inspected regularly for
wear or chipping. When replacing guides replace
all guides at the same time, both upper and lower.
b. In order to obtain satisfactory results, it is important
that the Blade Guide adjustments are properly
maintained at all times. Before carrying out these
adjustments, the blade must be correctly
tensioned, and tracking properly.
1. Upper Blade Guides
The Guide Block (K), carries the Blade Guides
(C1) and the Blade Support Bearing (E).
The Blade Guides provide side support for the
blade, and are adjusted as follows:
1.1 Lower the Upper Guide Block to its lowest
position and secure it.
Check the position of the Blade Guides. They
should be positioned so that they run in the
middle of the flat portion of the blade and
must NOT come into contact with the teeth
(see Fig.15).
Slacken off the screw (F), if necessary, using
the Hex. wrench provided. This allows the
guide housing to move in or out as required
Fig. 14
It is essential that this
adjustment is carried out
correctly, as it has a direct
bearing on the ability of
the saw to cut in a straight
line.
