Introduction

The FK350 and FK350-SX are circular saws designed to provide a reliable solution to the needs of machine shops and production environments that work with steel or iron. The FK350 is manually operated: after clamping the material in the vise, the operator presses the trigger handle starting the blade, and brings the operating lever downward to cut the material. The SX offers both semi-auto and manual mode. When in semi-auto mode, operator positions material, and then presses the cycle-start button. The saw control system activates the vise and clamps the material, and brings the head down completing the cut. The head then is raised and the vise released, completing the cycle. An optional foot switch is available to facilitate convenient cycle-start. The FK350 and FK350-SX can perform miter cuts up to 45º to the right or left.

FK350 Features

FK350 Cold Saw

FK350-SX Cold Saw

Features

Miter Cutting Head

The miter cutting head is the unit that cuts the material and consists of a cast iron base, blade support unit and guard, transmission unit, and motor. The depth of cut is set by adjusting the depth cut stop. The miter cutting head swivels and locks into -45º, 90º, and +45º by means of a locking mechanism. Depressing the mechanism overrides the lock, permitting the head to adjust

to any position between -45º and +45q.

Figure 1

Miter Position Lock

The miter position lock secures the miter cutting head from movement. The miter is secured when the lock is pushed all the way to the left and can be positioned when the lock is moved to the right.

Self-centering Vise

The self-centering vise holds the work piece in place during cutting. The work piece is secured in the vise by turning the vise handles.

FK350 Controls

The control panel consists of the Power (On/Off) switch and High/Stop/Low switch, and an integral coolant system. To operate the machine, the Power switch must be set to on and the High/Stop/Low switch must be set for Hi or Low. Then depress the trigger handle to start.

FK350-SX Controls

This machine features a 2-speed motor, feed speed control, an integral coolant system, and two modes of operation; manual mode, and semi-automatic mode. In semi-auto, the complete cut cycle is initiated via push button. The semi-auto cut cycle closes the vise clamping the material, powers the head down completing the cut, then raises the head, and opens the vise. In manual mode, head up/down, and vise open/close is initiated by switches.

Flood Coolant System

The coolant pump must be submerged before operating to prevent damage to the pump.

Coolant is dispensed directed onto the saw blade from a coolant fitting on the upper blade guard. Coolant is provided through tubing from the coolant pump (Figure 2) in the machine base.

Adjust the coolant flow valve on coolant fitting to achieve desired flow. When the coolant switch is in the ON position, flow starts when the drive motor is started. Turning off the coolant switch stops coolant flow.

This coolant system can operate with either a soluble oil base coolant or water-soluble synthetic coolant. Coolant should be changed regularly. Some recommended brands are DoAll and Lenox. These coolants are available at your local industrial distributor.

Trigger Handle

The trigger handle (Figure 1) is located on the operating lever used to raise and lower the saw.

It contains a micro-switch, which is activated when the operator depresses the run trigger.
