GA4040 100mm 1100W angle grinder

The GA4040 is a corded angle grinder manufactured by Makita.

In 2021 it as not listed on most of Makita's websites but was still listed on Makita India's website.

The machine is powered by a 1100 watt brushed electric motor.

Exterior

The body is barrel shaped with black rubber on the back and ventilation inlets on the sides.

The middle part is Makita teal colored plastic with a black slide switch that is used to activate the machine.

The front of the machine is the gear housing and is made out of aluminium. It has ventilation outlets on top and a black spindle lock button.

At the very front there is an indented arrow that indicates the turning direction. There are threaded inserts on each side to attach the side handle.

The gear housing can be unscrewed from the body and attached in four different positions. This is mostly useful for turning the body upside down to put the slide switch on the other side.

On the bottom of the gear housing is a 10 mm spindle on which the cutting disc or other tool can be screwed on. The disc is held in place with a lock nut for which a wrench is needed to loosen and tighten it.

Safety

Inside the gear housing is a vibration reduction system that Makita calls SJS (Super Joint System) II which absorbs some vibrations from the cutting disc to reduce the intensity of the vibrations passed on to the operator.
