Replacing V-Belts

1.DISCONNECT LATHE FROM POWER!

2.Perform Steps 2–3of the previous proce- dure.

3.Loosen the three top adjustment hex nuts, then raise the motor up by evenly rotating the hex nuts underneath the motor mounting plate until there is enough slack in the V-belts to roll them off the motor pulley.

4.Replace both V-belts at the same time, properly tension them as instructed in the previous procedure, then replace the access panels and secure the left side door.

Checking/Cleaning

Coolant System

Coolant is a potent and extremely poisonous solution to humans and animals. Use personal protective equipment when handling coolant to prevent infections or poisoning.

A screen in the splash pan keeps large swarf under the bedway where it can be removed dur- ing daily cleaning. However, smaller swarf washes down into the coolant tank where it is separated from the pump by a wall inside the tank. If this swarf builds up higher than the wall, then it over- flows into the pump chamber and clogs the pump. Regular cleaning of the reservoir will ensure the swarf never flows over the separating wall.

A small amount of coolant is lost during normal operation. Check the coolant tank daily and fill it if necessary. In addition, coolant eventually becomes rancid or contaminated with dangerous microbes, which makes it unsuitable for further use. When this happens, drain, clean, and refill the tank.

Checking Coolant Tank

When checking the coolant tank, the goal is to make sure there is enough coolant, the swarf level in the first chamber of the tank is not too high, and the coolant has not become contaminated.

Always use non-flammable water-based coolant to avoid explosions when the fluid comes in contact with hot metal chips from the milling operation. For best results, always follow the coolant manufacturer's recom- mendations for coolant/water ratios.
