MAINTENANCE
The maintenance schedule is listed below on the
basis of daily, weekly, monthly and six-monthly
intervals. Utmost care should be given to the
maintenance. Poor maintenance or neglecting
some of its requirements will result in premature
machine
failure
and/or
unsatisfactory
performance.
6.1.
Daily Maintenance
Clean/empty the chip reservoir whenever
necessary.
Use suitable brush with soft bristles. Do
not use hard materials to clean the
machine.
Check whether the emergency stop button
functions properly. Check that the entire
wheel covers other safety guards are in
place and fixed properly.
Check the wear on the teeth of the saw
blade.
Check the level of coolant.
Don not use pressured air for cleaning the
machine; expect for unblocking the
coolant pipes.
6.2.
Weekly Maintenance
Clean the wheels, vise, slides and
bearings.
Pull the movable jaws of the vise back
and clean the slides, beds and other
moving components and lubricate with
thin grease.
Apply grease to the main vise roller drive
mechanisms gearbox and vise roller
bearings. Check the condition of these
mechanisms and clean them if necessary
before applying grease. Use EP type
grease for vise roller drive mechanisms
gearbox.
Test the quality/condition of the coolant
and water/boron oil ratio; if necessary
renew it.
Non-painted parts should be wiped with a
clean cloth and oiled with protective
machine oil to prevent rust.
Coolant thank should be cleaned against
chips to prevent them accumulating onto
the floor of the tank.
6.3.
Monthly Maintenance
Check the level of hydraulic oil from the
site gauge. If the level drops below
indicated min. line, add hydraulic
system oil of grade 46.
Check the conditions of saw blade guide
bearings and carbide pressure pads at the
ends of guide arms. They should be
replaced when they become worn or
loose.
Check the gaps in the bearings of the
wheels. Replace them if they are won.
Check the condition of hydraulic systems
(cylinder/pistons, pipes/hoses, sealants
and hydraulic couplings.)
6.4.
Six-Monthly Maintenance
Perform all monthly maintenance checks
for six-monthly maintenance too. And
replaces those parts of the machine that
do not function as expected or that are
excessively worn.
Check the work stock feeding rollers for
wear and renew them if necessary.
Check the vise roller drive mechanisms
gearbox; renew the worn gear wheels if
necessary.
6.5.
Periodic Maintenance
Renew the wheel bearings.
Renew the carbide pressure pads and the
saw blade guide bearings.
Check the viscosity/condition of the
hydraulic oil. Renew if it is necessary.
Check the worn/damaged/malfunctioning
components that do not function properly.
