6.3 Adjusting the Upper Guides
To adjust the upper blade guides, first position the guide
assembly relative to the blade, by slackening off the hex screw
(Fig.6.4A) and moving the guide carrier until the roller guides
are just behind the gullets of the blade (See Fig.6.4). Next
set the roller guides as near as possible to the blade without
actually touching. This is done by unlocking and locking the nut
on each side of the guide adjustment
(See Fig.6.4)
. Do not let
the roller guides actually touch the blade as this will adversely
affect the life of the blade. Finally adjust the thrust bearing to
be just clear of the back of the blade
(See Fig.6.7) . Do this by
unlocking the hex socket screw (Fig.6.5B). When the correct
adjustment is reached, lock the thrust bearing in position with
hex socket screw
(Fig.6.5B) .
6.4 Adjusting Lower Guides
To adjust the lower blade guides, first slacken off the hex socket
screw
(See Fig.6.8A)
, move the guide carrier casting so the
guides are just behind the gullets of the blade . Next set the
roller guides as near as possible to the blade without actually
touching. This is done by releasing the hex head socket screw
(See Fig.6.8B) on each side of the blade. Finally adjust the
thrust bearing to be just clear of the back of the blade
(See
Fig.6.9) . To do this first unlock the Hex socket screw (See
Fig.6.8C) then using the adjustment knob at the rear, position
the thrust bearing Fig.6.10 .
6.5 Adjusting the cutting height
Once the blade is set, the cutting height must be adjusted so
there is maximum guarding for the blade. Also so the blade
guides are providing optimum support to the blade.
To adjust the cutting height loosen the rise and fall lock knob
and turn the rise and fall handwheel to raise or lower the guide
post/upper blade guide assembly to the desired height
Fig.6.11 .
Note: The upper blade guide should provide approximately
5mm clearance above the workpiece. After the desired position
has been set tighten the ris and fall lock knob.
