Unpacking

Open shipping container and accessory boxes, and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Band Saw is assembled and running properly.

Compare the c ontent s of y our cont ainer wit h t he following parts list to make sure all parts are intact. Mi ssing parts, i f any, should be reported to your distributor. Read the instruction manual thoroughly for assembly, maintenance and safety instructions.

Read and understand the entire contents of this manual before attempting set-up

or operation! Failure t o co mply may cause serious injury.

Installation and Assembly

Remove all crati ng and plastic from around the band saw. Remove any lag screws or holding straps which secure t he band saw to the wood pallet.

Unpainted areas of the machine have been treated with a r ust prevent ative. This should be removed wit h a soft clot h and a mil d solvent . Do not use paint thinner, lacquer thinner, gasoline or mineral spirits; these will damage painted and plastic surf ac es. Do not use an abrasive pad.

Installing Motor

Mount the motor to the gearbox using the four M10 x 30 socket head c ap screws and f our M 10 lock washers, through the holes in the motor’s flange. See F i gure 1. The key in t he m otor shaf t must line up with the keyway in the gearbox opening.

Wheels and Leveling Stands

1. Slide the band saw at an angle so that the

edges hang over the sides of the pallet.

2. Insert t he axle thr ough the holes at t he right

end of the band saw cabinet (opposite the end where the lifting handle is mounted). See Figure 2.

3. Install a wheel and two f lat washers on eac h

end of the axle. Insert a spli t pi n through the hole in the axle and bend the ends of the split pin to secure the wheel on the axle.

4. Install t he two leveling stands at t he left end

of the band saw (the end where the lifting handle is mounted). See Figure 2. Screw the leveling stand i nto the hole beneath the band saw cabinet, and tighten the top hex nut against the bott om of t he cabi net.

5. The leveli ng st ands can be later adjusted for

level by r otating the stand and re-tighteni ng the hex nut against the c abinet.

6. Roll the band saw off the pallet.

Figure 1

Figure 2

Stock Stop

1. Insert t he stock stop rod i nto the hol e at t he

front of the base (Figur e 3) .

2. Secure the rod by tightening the hex cap

screw below the casting.

3. Slide the stock stop onto the rod, and

tighten the t humb screw. The stock stop can be mounted so it faces either direction.

Figure 3

Shut-Off Switch

Remove the screw and hex nuts which hel d the bow to the base during shipm ent. These should be retained in case of future transportation of the Band Saw.

The screw below the limit switch, shown in Figure 4, has been pre-set at the factor y so that the switch will contact the screw and stop the blade after each cutting operation.

Coolant Hose

Before operati ng, the coolant dr ain hose (Figure

5) must be connected to the coolant pan and the other end of the hose placed into the filter c up in the tank as shown.

The hose from the coolant pump i s attached to a valve which should be i nserted into the hole on the guide assembl y (see Fi gur e 17) .

Grounding Instructions

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

This mac hine m ust be grounded. I n the event of a malfuncti on or break down, groundi ng prov i des a path of least r esistance f or electric current to reduce the ri sk of el ectri c shock .

This band saw is pre-wired f or 115 volt and is equipped with an electric cord having an equipment-grounding conductor and a grounding plug si mil ar to that shown in Fi gure 6. The plug must be inserted int o a matching outl et that is properly installed and grounded in accordance with all local codes and ordinances.

Figure 4

Figure 5

Do not modify the plug provided. If it will not fi t the outlet, have the proper outlet installed by a qualified elec trician.

Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. The conductor, with insulation having an outer surface that is green with or without yellow stripes, is the equipmentgrounding conduct or. If repai r or replac ement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the machine is properly grounded.

Figure 6

115 Volt Operation

As received fr om the f actory, your band saw is ready to operate at 115 volt power, using an outlet and a plug that look similar to those illustrated in Figure 6.

A temporary adapter, which looks like the adapter illustrated in Figure 7, may be used to connect this plug to a two-pole receptacle as shown, if a properly grounded outlet is not immediately available. The temporary adapter should only be used until a properly

grounded outlet can be installed by a qualifi ed el ect rician.

The green colored rigid ear, lug or tab, extending f rom the adapter must be connec ted to a permanent ground such as a properly grounded outlet box, as shown in Figure 7.

Make sure the voltage of your power supply matches the specif ications on the m otor plate of the Band Saw.

Conversion to 220 Volt

If 220 volt, single phase operation is desired, t he following inst r uc tions must be followed:

Figure 7

1. Disconnect machine from power source.

2. Open the electrical box and change the

position of the fuse from the 115V slot to the 220V slot. An el ectrical drawing is included inside the elect rical box, and is also shown on page 31 of this manual.

3. The 115V att achm ent plug suppl ied wit h the

band saw must be repl aced with a UL-li sted plug suitable for 220 volt operation. The band saw must comply with all local and national codes after the 220 volt plug is install ed. The band saw with a 220 volt plug should only be connected to an outlet having the same configuration (Figure 8). No adapter is available or should be used with the 220 volt plug.

Extens ion cords

If an extensi on c or d is necessary, m ak e sure t he cord rating i s suitable for the am perage listed on the machine’s motor plate. An undersized cord will cause a drop in line voltage resulting in loss of power and ov erheating. Use only three wire extension cords that have three-prong grounding plugs and three- pole recept acles that accept the mac hine’s pl ug.

Use the chart in Fi gure 9 as a general guide in choosing the c orrect size cord. If in doubt, use the next heavi er gauge. The small er the gauge number, the heavier the cord.
