Remove the packaging materials from around your machine and inspect it. If you discover the machine is damaged, please immediately call Customer Service at (570) 546-9663 for advice.
Inventory Clean Up The following is a description of the main components shipped with your machine. The unpainted surfaces are coated with a waxy oil to prevent corrosion during shipment. Remove this protective coating with a solvent cleaner or degreaser shown in Figure 4. For thorough cleaning, some parts must be removed. For optimum performance from your machine, clean all moving parts or sliding contact surfaces.
Site Considerations Moving & Placing Machine Workbench Load Refer to the Machine Data Sheet for the weight and footprint specifications of your machine. Some floors may require additional reinforcement to support both the machine, the workbench and the workpiece. To move your machine into position: 1. Move the shipping crate next to the mounting table or stand. 2. Remove the mounting bolts holding the mill to the bottom of the crate.
Mounting Assembly Once you have determined that the inventory is complete, mount the machine to a workbench through the holes in the base. We recommend that you cut a hole in your bench top to allow access to the under side of the base on the machine. This will be necessary for adjusting the Y-plane leadscrew. Refer to Leadscrew Backlash on Page 33.

To reduce the risk of serious injury when using this machine, read and understand this entire manual before beginning any operations. Damage to your eyes could result from using this machine without proper protective gear. Always wear safety glasses or a face shield when operating this machine.
Micro-Adjustment Handwheel: Provides fine control over vertical spindle travel. Longitudinal Travel Handwheels: Control longitudinal (X-Axis) travel of the table. Locking Knob: Engages/disengages the microadjustment handwheel. Cross Travel Handwheel: Controls cross (Y-Axis) travel of the table. Quill Downfeed Levers: Provide coarse control over vertical spindle travel. Table Locks: Lock the table in position along their respective axes. Travel Stops: Limit longitudinal table travel.
Collet/Arbor To remove a collet or an arbor: 1. DISCONNECT MACHINE FROM POWER! The Model G3358 features an R-8 spindle which accepts many industrial collets and arbors. To install a collet or an arbor: 1. DISCONNECT MACHINE FROM POWER! 2. Release the latches on the head cover and open it. 3. Make sure the tapered mating surfaces of the collet or arbor and the spindle are clean and free of grease or other impurities. 2. Loosen but do not remove the drawbar. 3.
Spindle Height The Model G3358 has coarse downfeed levers and a micro-adjustment handwheel. To operate the downfeed levers, simply pull forward and down on the lever nearest you. The spindle will go down until you stop pulling or until it hits the depth stop. To operate the micro-adjustment handwheel: 1. Tighten the locking knob located on the center of the hub for the downfeed levers (Figure 22). This transfers control from the downfeed levers to the micro-adjustment handwheel.
Headstock Height Depth Stop The headstock height on the Model G3358 can be adjusted for various applications. For best results during milling, keep the headstock fully retracted and set the headstock as low as possible. The depth stop is used to limit the range of downward movement by the drill bit or cutter. Maximum depth is 5". To adjust the headstock height: 1. To calibrate the depth stop: 1. Install the cutting tool, then make sure the spindle is drawn all the way up into the head.
Speed Changes 3. Loosen the two idler pulley bolts that hold the idler pulley in place so the pulley can move freely (Figure 27). The Model G3358 is capable of twelve different speed settings. Different types of cuts and materials require varying speeds. Refer to the chart in Figure 29 for appropriate cutting speeds. Idler Pulley Bolts To change spindle speeds: 1. DISCONNECT MACHINE FROM POWER! 2. Loosen the motor locking lever.

Return Spring The spring’s tail is located on the perimeter of the spring housing. This part may be sharp! Use leather gloves or a heavy shop towel to cover the tail while loading or unloading return spring pressure. Failure to use such precautions may result in personal injury. 4. Put on gloves and pull the spring cover out enough so the notches just clear the roll pin. Hold the spring cover tightly or the force of the spring will spin it out of your hands. 5. Rotate the cover to adjust the tension.
Leadscrew Backlash When you turn the handwheels to adjust the position of the table, you will notice slight play (backlash) in the handwheel before the table begins to move. If this play is greater than 0.008" (measured with the dial at the base of each handwheel), then you will need to adjust the leadscrews. These adjusters may require you to fabricate extensions for your hex wrenches. Make adjustments in small increments. Over-tightening to attempt to reduce backlash to less than 0.
