CHAPTER VI: 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.
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.
2- WEEKLY MAINTENANCE

Clean the wheels, vice, slides and bearings.

Pull the movable jaws of the vice back and clean the slides, beds and other moving
components and lubricate with thin grease.

Apply grease to the main vice roller drive mechanisms gearbox and vice roller bearings. Check
the condition of these mechanisms and clean them if necessary before applying grease. Use EP
type grease for vice 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.
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 worn.

Check the condition of hydraulic systems (cylinders/pistons, pipes/hoses, sealants and
hydraulic couplings).
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 vice roller drive mechanisms gearbox; renew the worn gear wheels if necessary.
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.

Renew the worn/damaged/malfunctioning components that do not function properly.
