Record Power BS250 - Drive Belt and Blade Guide System Maintenance

10.2 Replacing the drive belt
Note: Circlip pliers are required for this
procedure
To replace the drive belt
slacken the
tension on the belt by loosening the
motor pivot Allen bolt on the back of
the machine, lifting the motor and re-
tightening the bolt
Fig.10.4. Ease the
drive belt off the motor pulley
Fig.10.5.
Ensuring that there isn't a blade fitted
now remove the lower bandwheel
by releasing the circlip from the hub
Fig.10.6. Remove the old belt and fit the
new one
. Once the drive belt is in place
re-fit the lower bandwheel
Fig.10.7. Now
tension the drive belt by loosening the
motor pivot allen bolt and lowering the
motor until adequate tension is applied
Fig.10.8.
Tip: As a guide the belt is correctly
tensioned when using the index finger
to impart reasonable pressure on the
belt should not deflect more than 1/4".
But like tensioning a blade a bandsaw
blade this is subjective and the best
test is if the belt is not slipping or
wearing excessively and there is
adequate power being applied to the
bandwheels then the drive belt is
tensioned correctly.
10.3 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 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 simply undo
the Allen bolt which is used to make
adjustment and slide the unit completely
out of the housing
Fig.10.9. This unit can
now be separated by unscrewing the
cylindrical slide piece
Fig.10.10. Replace
the bearing and reassemble.
To change the thrust bearing, undo
the Allen bolt completely and r
emove
Fig.10.11. The bearing itself can now be
replaced and refitted
.
When replacing components on the
lower guide assembly, undo the Al
len
bolt completely and r
emove Fig.10.12.
CAUTION!
Before carrying out any adjustments
or maintenance ensure that the
machine is isolated and disconnected
from the electricity supply.
