3. Maintenance
Due to its sturdy structure and the sealed ball bearings requiring no
extra lubrication, the general maintenance of Discotom-2 can be
confined to cleaning of the machine and the cooling system,
lubrication of the quick-clamping devices, oiling of the cutting table
and tightening (exchange) of belts.
Cleaning consists in removal of abraded particles from the cutting
table, the sieve and the bottom of the wheel chamber. After cleaning
unpainted surfaces should be oiled to avoid corrosion. Painted
surfaces may be cleaned with a damp cloth. The cooling water
should always contain a quantity of Additive for Cooling Fluid, the
required concentration being stated on the packing.
The quick-clamping device should be greased at intervals of two to
five days, depending on usage. The spindle tilting bearing (fig. 12.5)
should be greased through the nipple (fig. 13.3) every six months.
Belt tightening (belt exchange) is effected by detaching the front
plate and the rear part of the cabinet (the main switch must be
blocked with a padlock before the front plate is removed) and
slackening the four bolts securing the motor. Then the motor can be
pushed rearward to tighten the belts, after which the motor is
secured again. The pressure of a finger applied to the belts about
half-way between the pulleys must cause them to yield only approx.
10 mm. The belts should be tightened every six months, or so, or
whenever they screech under load.
