2004/108/CEE On “Electromagnetic Compatibility”. 1.2 Warranty Scotchman Industries, Inc. will, within two years of the date of purchase, replace F.O.B. the factory or refund the purchase price for any goods which are defective in materials or workmanship, provided the buyer, at the seller’s option, returns the defective goods freight and delivery prepaid to the seller, which shall be the buyer’s sole and exclusive remedy for defective goods.
2.0 GENERAL MACHINE INFORMATION 2.1 Machine Identification Data MODEL - GAA-500-90 DT20 ___________________________ SERIAL NUMBER ___________________ YEAR OF MANUFACTURE ➢ NOTE: IN ORDER TO REQUEST SPARE PARTS, WHETHER COVERED BY THE WARRANTY OR NOT, ALWAYS INDICATE THE MODEL AND SERIAL NUMBER OF THE MACHINE, AS WELL AS THE NAME OF THE PART AND THE PART NUMBER THAT APPEARS IN THE FOLLOWING PARTS DIAGRAMS WITHIN THIS MANUAL.
BEFORE signing the delivery paperwork. If damage is seen, refuse the shipment and notify Scotchman. DO NOT ACCEPT DAMAGED EQUIPMENT. This makes filing damage claims with the shipping company impossible and will make the customer responsible for the damage repair costs.

Once the machine is connected, verify that the saw blade rotation is away from the operator when the operator is standing in front of the machine. If the saw blade rotation is wrong, swap two phases of incoming power to the machine. Then check for proper rotation again. ➢...
4.3 Pressure Regulator The air inlet location is shown below. The air regulator must be set at 6.5 to 7.2 bar (90 to 105 psi). The red knob on top is used to turn the air supply on or off. Do not add oil to the regulator. The pneumatic components of this machine are internally lubricated with grease.
4.5 Belt Removal and Installation To remove the belt, simply roll it off the pulleys. Do not loosen the motor. Do not pry on the aluminum pulleys or they will get damaged. If the motor has been loosened or removed, it must be realigned. Use a straight edge across the end of the motor pulley and spindle shaft pulley to align the pulleys back again.
4.7 Priming/Adjusting the Coolant Mister The following procedure explains how to adjust the coolant mister or prime the system if it has run out of coolant. This job requires 2 people in order to safely perform. Make sure to adhere to the following instructions.
4.8 Cleaning the Coolant Mister The coolant mister can be removed and disassembled for cleaning. It works on a venturi principle. Some of the blade cylinder supply air is diverted to the mister when the blade is advancing up. The air flow through the venturi creates suction that draws the oil from the bottle on the exterior of the machine.
4.9 Blade Advance Oleo-Pneumatic System The oleo-pneumatic system for the blade advance on a GAA machine is a sealed system. It must be filled with AW32 or 10w non-foaming hydraulic oil. This system can be customer serviced, but it requires advanced hydraulic tools and is therefore usually replaced as a complete assembly pre-filled.
4.10 Feed Shuttle Oleo-Pneumatic System The oleo-pneumatic converter must be filled with AW32 or 10w nonfoaming hydraulic oil through the threaded plug above the sight glass on the rear of the machine until the level reaches the center of the sight glass.
5.0 INSTRUCTIONS FOR USE 5.1 Proper and Improper Use This is an automatic cold saw especially designed for cutting non-ferrous material. The use of this machine for cutting ferrous materials is strictly forbidden and may lead to machine damage as well as serious injury.
5.3 Operation of the Machine MANUAL MODE: One cut at a time. 1. Turn on power at the disconnect switch. The green power lamp (F) should illuminate. 2. Turn the auto/manual switch (O) to the center “hand” position for manual mode. 3.
*Note: These counters are programmed devices specifically for the GAA-500-90. If the advanced programming is inadvertently modified from the factory default, contact Scotchman for programming instructions to return the counter to the Scotchman factory settings. 5.5 General Rules and Safety Checks ➢...
5.6 Drill Setup The Drill on a GAA 500 90 DT20 is a complex piece of equipment. It has a two stage advance speed control to handle fast approach and working speed, two stage tool speed to handle drilling and tapping speed, total stroke control, and up/down sensors.
➢ Whenever any part has to be replaced, use an original replacement part and use lubricants as recommended by Scotchman in the table above. ➢ Follow the maintenance schedule as listed above. ➢ Note: In case of any doubt or problem, do not hesitate to contact Scotchman: (605-859-2542).

If the motor has a solenoid friction brake (in the fan shroud), it is a single voltage motor and must be replaced. Dual Voltage Motor Wiring (BRAKELESS MOTOR ONLY) 230 V (Delta) 460 V (Wye)
6.5 PLC and Sensor Troubleshooting and Adjustment Note the PLC on the GAA-500-90-NF is equipped with indicator lamps for the operator to determine which inputs and outputs are active. Inputs are on the top row. Outputs are on the bottom row. Viewing these lamps are very helpful in determining issues.
