14. Maintenance - Cont.
The Blade Guide System
In general usage it is advisable to carefully apply silicone
spray to the blade guides to ensure free movement of the
rollers, do not use oil or grease for lubrication as this will
attract dust and cause the rollers to jam. The blade guide
system is a consumable item and depending on usage will
wear and may need replacing.
CAUTION!
It is advisable that the blade has been
removed from the machine before replacing the blade
guide components.
When replacing components on the upper guide assembly,
loosen the guide carrier locking knob (Fig. 14.5, A) and remove
the whole assembly.
When replacing components on the lower guide assembly,
remove the pivot bolt (Fig 14.6, A) and then remove the
whole assembly.
To change the side roller guides (Fig. 14.5), unscrew the
locking ring (Fig. 14.5, A) and unscrew the roller support shaft
(Fig. 14.5, B). As the support shaft is removed from the guide
support casting, the guide roller will be extracted from the
shaft. Replace the roller and re-assemble.
For full details on adjustment of the blade guides please see
the bandsaw blade setup section of the manual.
The Table Insert
The table insert on a bandsaw is a consumable item
(Fig. 14.7 A) and will therefore need replacing periodically.
This procedure should be carried out with the bandsaw blade
removed. To replace the table insert simply push the old insert
out from underneath the table and fit the new one
into position.
The Bandwheel Tyres
The bandwheels on this machine have rubber tyres fitted to
the outer rim of the wheel (Fig. 14.8, B) to protect the set of
the blade when in use, also to provide drive and to stop the
blade slipping. As part of your regular service schedule inspect
the tyres for wear and damage and replace if necessary.
Again this is a consumable part of the bandsaw and will need
replacing periodically depending on usage. First remove the
blade from the bandsaw, then remove the bandwheel. Gently
ease the existing tyre from the rim taking care not to damage
the bandwheel. To fit the new tyre it is a good idea to heat the
tyre first in hot water, this softens the rubber up and makes
it easier to stretch it over the bandwheel. The tyres before
stretching are much smaller than the bandwheel and a good
deal of stretching is required to make them fit. It is advisable
to get help from a second person who can insert the wheel
into the tyre while it is fully stretched.
