Installation, Maintenance, Service & Part List Manual

Coolant System Diagnostics
The coolant system consists of a 115 volt coolant pump, coolant tank and various hoses that supply coolant
to various aspects of the machine. See drawing 27557 located in the rear of the manual.
Coolant capacity is approximately 55 litres.
5.10.1
Coolant pump
The coolant pump serves 2 purposes. It supplies coolant to the cutting tool and also washes swarf away
from the rear of the table so the ATC can move freely. If the coolant wash is not working properly to clean
swarf away, it could lead to the ATC not moving forward enough which may lead to error messages or a
possible machine crash when changing tools.
5.10.2
Coolant Wash Nozzles
The coolant wash nozzles supply coolant to the rear of the table via 2 nozzles. The nozzles are flexible and
should be positioned to provide effective clearing of swarf from the path of the ATC to ensure reliable ATC
operation.
5.10.3
Chip Coolant Screen
The coolant tank contains a mesh screen to filter out any swarf or debris from the coolant return. See
drawing 27557, item 8. Depending on the machine usage, and the material being machined, this screen
may need to be cleaned at various intervals. If the coolant is not draining fast enough and causes low
coolant flow, the screen needs to be cleaned. The screens simply rests on top of the coolant tank.
5.10.4
Coolant Hoses
There are 2 coolant hoses attached to the coolant pump. One hose delivers coolant to the nozzle on the
head and the second; to the coolant wash nozzles.
5.10.5
Coolant Drain Plug
There is a drain plug near the bottom left corner on front of the machine to permit draining of the coolant
tank.
5.10.6
Coolant level Sight Gauge
An external, coolant level sight gauge is mounted on the front of the coolant tank. It gives the operator an
easy way to visually check how much coolant is in the tank.
5.10.7
Rear Drain Plug
At the rear of the machine, there is a drain plug in the floor that can be removed to drain any coolant that
collects in the rear compartment of the machine. Over time, some coolant may accumulate in this area.
5.11
Service Codes
Warning!
Certain service codes must be performed when servicing certain items on the 2 OP. Failure to do so can
lead to machine crashes and expensive repair work. Do not work on the TRAK 2 OP unless you have
been trained on these service codes.
Please see the table at the end of this section for the list of service codes that must be run when certain
machine components are worked on.
Service codes are broken down into the following groups: software, machine setup, diagnostics, user
options/defaults.
The table below is a quick summary of the service codes; more detailed information follows.
