9. Bandsaw Blade Set Up - Cont.
CAUTION!
Before carrying out any adjustments or
maintenance ensure that the machine is isolated and
disconnected from the electricity supply.
First check that all 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 grub
screws (Fig. 9.5, A) and moving the guide carrier
(Fig. 9.5, B) until the roller guides (Fig. 9.6, C) are just
behind the gullets (Fig. 9.6, B) of the blade.

Next set the roller guides (Fig. 9.7, A) as near as possible
to the blade (Fig. 9.7, B) without actually touching. This
is done by unlocking the nut on each side of the guide
adjustment (Fig. 9.5, D). Do not let the roller guides
actually touch the blade as this will adversely affect the life
of the blade.
Finally adjust the blade support roller (Fig. 9.7, A) to be
just clear of the back of the blade (Fig. 9.7, B). Do this by
unlocking the grub screw (Fig. 9.5, D).
When the correct adjustment is reached lock the blade
support roller in position.
