6 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.

Do not use pressured air for cleaning the machine; except 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 tank should be cleaned against chips to prevent them accumulating
onto the floor of the tank.
6.3 Monthly Maintenance

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 worn.

Check the condition of hydraulic systems (cylinders/pistons, pipes/hoses,
sealants and hydraulic couplings).
6.4 Six-Monthly Maintenance

Perform all monthly maintenance checks for six-monthly maintenance too.
And replace 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.
