6.3 Adjusting the Upper Guides
First check that all of the roller guides are moving freely. 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.6.6).
Next set the roller guides as near as possible to the blade without
actually touching. This is done by unlocking the knurled 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 a hex
wrench
(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 rear 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.6.9A)
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 and so that 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 5 mm clearance
above the workpiece. After the desired position has been set tighten the
rise and fall lock knob.
Note:
Because this machine is able to take a range of different width
blades, the blades may track at different positions. After each alteration
of the cutting height never assume the guides are in the correct position.
If necessary, re-adjust the guides as shown above.
